 The payload fairing for SpaceX's upgraded Falcon 9 rocket, set to debut this summer on a launch from California, is being tested inside the world's largest vacuum chamber in Ohio as the burgeoning space transportation company breaks in to the commercial launch market.

 The 17-foot-diameter shroud was built entirely by SpaceX for the company's next-generation Falcon 9 rocket - called the Falcon 9 v1.1 in SpaceX's parlance.

SpaceX is testing the fairing inside the world's largest vacuum chamber at NASA's Plum Brook Station in Sandusky, Ohio. The cavernous chamber, which can simulate the pressure, temperature and radiation environments of space, has been used to test U.S. and European launcher fairings, Mars landers and International Space Station hardware.

The Hawthorne, Calif.-based space transportation company released a video of the fairing test Thursday, showing the shroud's two clamshell-like halves separating in high-speed camera views.

The 43-foot-tall fairing will enclose satellites in the first few minutes of launch as the Falcon 9 rocket flies through the lower atmosphere. Once the launch vehicle reaches thinner air resistance at the edge of space, it will jettison the fairing to let go of the extra mass.

Elon Musk, SpaceX's CEO and chief technology officer, said the payload fairing is made of carbon fiber with an aluminum honeycomb core. He called it "the lightest material choice possible" in an email with Spaceflight Now.

The fairing tests continue at Plum Brook, according to Christina Ra, a SpaceX spokesperson.

The Falcon 9 v1.1's upgraded Merlin engine completed qualification for flight earlier this year. The Merlin 1D engine produces more thrust than SpaceX's previous Merlin engines, and its design is more robust for reusability, higher production rates and lower cost, according to SpaceX.

The Falcon 9 rocket's first stage is powered by nine Merlin engines. SpaceX redesigned the upgraded Falcon 9's first stage to arrange the engines in a circular pattern instead of the "tic-tac-toe" three-by-three engine matrix used on the first-generation Falcon 9 booster.

A vacuum-rated Merlin 1D engine with an expansive nozzle will propel the Falcon 9 v1.1's second stage.

SpaceX's Falcon 9 qualification testing, which is not yet complete, is also verifying the structural integrity of the new rocket's first stage tanks, which are stretched to hold more liquid oxygen and kerosene propellants than previous Falcon 9s.

The maiden flight of the Falcon 9 v1.1 is scheduled for July from Vandenberg Air Force Base, Calif., with the Canadian Space Agency's Cassiope communications and space weather research satellite.

The upgraded Falcon 9's first launch from Cape Canaveral, Fla., will come in August with the SES 8 communications satellite. It will be SpaceX's first launch into geostationary transfer orbit, a high-altitude elliptical orbit commonly used by communications satellites transiting to operational positions over the equator.

All of SpaceX's Falcon 9 launches to date have flown to low Earth orbit on test flights or NASA-sponsored missions to resupply the International Space Station with the Dragon spacecraft.

Unlike most satellites, launches of the Dragon capsule do not use a fairing.

Spacecraft Are 33rd and 34th GEOStar Satellites Produced for Customers Around the Globe

In June and July, Orbital delivered the Thaicom-6 GEOStar communications spacecraft to one of Orbital's newest customers, Thaicom PLC of Thailand, and the SES-8 spacecraft to SES of Luxembourg, a repeat GEOStar customer for Orbital. A hybrid Ku- and C-band spacecraft based on Orbital's GEOStar-2 spacecraft bus design, Thaicom-6 will provide a full range of end-to-end satellite communications services over Southeast Asia and Southern Africa, including direct-to-home and digital TV services.
Also based on Orbital's GEOStar-2 design, SES-8 will provide Ku-band communications for South Asia and Indo-China and Ka-band communications for the Asia-Pacific region.
Generating approximately five kilowatts of payload power, the hybrid satellite is the sixth GEOStar satellite to be ordered from Orbital by SES. Both SES-8 and Thaicom-6 are scheduled for launch on Falcon 9 rockets from Cape Canaveral, Florida later in 2013.
SES-8 and Thaicom-6 represent the 33rd and 34th GEOStar-based satellites ordered by customers around the globe. Optimized for small- and medium-class satellite missions, Orbital's highly successful GEOStar communications satellites provide up to eight kilowatts of payload power and can accommodate virtually all types of commercial communications payloads. Orbital expects to confirm orders for several new GEOStar communications satellites from new and repeat customers in the coming months.

PARIS — Satellite fleet operator SES will await a detailed briefing from SpaceX on why SpaceX's new-version Falcon 9 failed to perform a planned reignition of its upper stage — crucial for deployment of the SES-8 satellite awaiting a Falcon 9 launch — during its Sept. 29 demonstration flight, SES spokesman Yves Feltes said Oct. 2.
In an interview, Feltes said Luxembourg-based SES nonetheless still expects SES-8 to be the payload on the next Falcon 9 launch. The mission, scheduled to take place in the coming weeks, will be the Falcon 9's first to geostationary transfer orbit, the dropoff point for most telecommunications craft.
Among the new features to be proved during the maiden flight of the Falcon 9 v1.1 rocket was the ability of its upper stage to perform a second ignition. While it was not needed for the Sept. 29 mission, which deployed multiple satellites to low Earth orbit, it is a necessary feature for launches into geostationary transfer orbit.
Hawthorne, Calif.-based Space Exploration Technologies Corp. (SpaceX) has a backlog of more than $1 billion in commercial satellite launches, more than half of which is for owners of geostationary-orbiting telecommunications satellites.
SpaceX's low prices relative to the competition — even compared with the Chinese Long March vehicle — have enabled the company to amass a healthy commercial backlog despite having never launched to geostationary transfer orbit.
SpaceX officials said after the Sept. 29 launch that the nonignition of the upper stage did not appear to be of a sort to delay the SES flight for very long. Feltes said SES is will hoping for a launch as soon as October, but added that if it slipped to November the company was willing to wait.
The fact that SES will be awaiting details from SpaceX "does not mean that we reject the flight as a qualification flight," Feltes said. "We still plan to be on the next Falcon flight, once SpaceX has solved the problem. But we need a technical explanation. We do need reignition of the stage for our satellite."
The shutdown of the U.S. government has rendered moot the date of SES-8's launch from Cape Canaveral Air Force Station, Fla. Feltes said no new launches are moving forward during the shutdown. SES-8's manufacturer, Orbital Sciences Corp. of Dulles, Va., is weighing whether to send the satellite to Florida aboard a truck once SES has authorized its shipment to the spaceport.

Цитировать SES Reviewing Falcon 9 Upper Stage Reignition Abort Ahead of SES-8 Launch
 
 Posted by Amy Svitak 1:38 PM on Oct 02, 2013  
  SpaceX says its Falcon 9 v1.1 upper stage aborted an attempted reignition of the new Merlin vacuum engine during Monday's debut of the upgraded rocket. Second-stage reignition is necessary for Falcon 9 to deliver payloads to geostationary transfer orbit (GTO).  

"The second-stage engine initiated ignition, got up to about 400 psi, encountered a condition it didn't like and initiated an abort," SpaceX spokeswoman Emily Shanklin said Oct. 2. "We need more time to review the data before we come to any sort of definitive conclusion, but we are confident we will be able to address it before the next flight," she said, adding that the abort "wasn't anything fundamental" and that a planned late-October launch of the SES-8 satellite for Luxembourg fleet operator SES "is still on track to launch in about a month."

SES says it is now discussing the reignition abort with SpaceX ahead of the launch, which could also be delayed by the U.S. government shutdown as it affects operations at Cape Canaveral AFS, where the Orbital Sciences Corp.-built SES-8 spacecraft is to be launched.

ЦитироватьNew Falcon 9 Falls Short On Stage Functions

SpaceX engineers will have some changes to make on the company's new Falcon 9 v1.1 launch vehicle before its next mission, following lessons learned from its Sept. 29 demonstration flight.
A preliminary test of an innovative reusable-booster concept intended to hold down costs showed the need for more work after an uncontrollable spin apparently hampered pre-spashdown braking. The vehicle also aborted a planned restart of its upper-stage engine during the otherwise successful debut of the upgraded rocket.
With more than $1 billion in commercial-launch backlog, restarting the Merlin 1D vacuum engine that powers Falcon 9's upper stage is critical to delivering government and commercial satellite payloads to geostationary transfer orbit (GTO), the destination of most commercial telecom spacecraft. But SpaceX CEO/Chief Technology Officer Elon Musk downplayed the upper-stage restart, characterizing it as an "optional" part of the flight profile.
"We essentially saw the engine initiate ignition, get up to about 400 psi, and then it encountered a condition it didn't like, and we think it may have been due to an extended spin start—maybe, this is speculative—and so it initiated an abort of the restart," Musk said post-launch. "We have all the data from the restart, so I'm confident we'll be able to sort it out and address it before the next flight."
That mission is expected to loft the new rocket's first GTO mission—the SES-8 telecommunications satellite for fleet operator SES—late this month.

Спойлер

Longer term, SpaceX wants to reuse hardware to hold down costs. The Falcon 9 v1.1 flight included an attempt to slow the hypersonic first stage for a controllable descent to the Pacific Ocean. Before launch, Musk gave this only a slim chance of working on the demo flight, but it seems it was at least partially successful.
Following main-engine cutoff, burnout and separation, with the stage likely slowing well below Mach 10, three of its nine engines were intended to fire to decelerate the booster for its initial descent. A single engine was then due to fire to perform a final braking maneuver just before the stage impacted the ocean at a slow, landing-like speed.
While the initial high-altitude retrofire sequence appeared to work to plan, Musk said the stage "actually ended up spinning to a degree that was greater than we could control with the gas thrusters, and it centrifuged the propellant. It caused the boost stage to run out of propellant before hitting the water. So it hit the water relatively hard."
The stage lacked the landing gear that Musk says would help stabilize a reusable unit. SpaceX's reusability plan builds on a vertical landing and recovery system that has undergone initial tests at the company's facility in McGregor, Texas, using the Grasshopper demonstrator. Although only a foreshortened Merlin 1D-powered first stage, the Grasshopper's precise maneuvers and landings have bolstered confidence in the concept.
"Between this flight and Grasshopper tests, we now have all the pieces of the puzzle to bring the rocket back home," said Musk. "If things go super well, then we will be able to re-fly a Falcon 9 stage before the end of next year."
SpaceX plans to test a larger version of the Grasshopper, also dubbed the Falcon 9R (reusable)—with nine -1Ds more representative of the upgraded production launch vehicle—at a specially constructed site at Spaceport America in New Mexico.
As for the upper-stage abort, Musk said the Merlin 1D has been successfully reignited "dozens of times" during ground tests, but he conceded the company still needs to address minor technical issues associated with operating the engine in the vacuum of space.
"We just need to iron out the differences between restarting in vacuum and in microgravity versus restarting on the ground," he noted. The issue could delay the launch of the SES-8 satellite by "a few extra weeks, to make sure we're super-confident of the second-stage restart," he added.
Musk said the Falcon launch vehicle that will loft SES-8 is at SpaceX's Cape Canaveral AFS launch facility.
"We're ready to go with SES, with a steady cadence of launches thereafter," he said, which would include the Thaicom 6 anticipated later this year, followed by SpaceX's third cargo resupply mission to the International Space Station (ISS) in February.
SES is discussing the reignition abort with SpaceX, and at press time it had not yet shipped the Orbital Sciences Corp.-built spacecraft to the Cape, which ceased operations last week with the U.S. government shutdown.
Beyond reusability and upper-stage reignition, there were several other key milestones for the upgraded Falcon 9. It successfully delivered the first of six payloads into orbit 14 min. after it left the pad. These included the Canadian-built CAScade, Smallsat and IOnospheric Polar Explorer (Cassiope) satellite, Canada's first space environment sensor suite.
Major modifications to the new Falcon include the more powerful Merlin 1D engines, arranged for the first time in an "Octaweb" pattern with a central engine surrounded by eight other engines, rather than the former 3 X 3 configuration of previous Falcons. The Octaweb thrust structure also supports the higher thrust of the Merlin 1D, each of which develops 147,000 lb. thrust at sea level, rising to 161,000 lb. at altitude. Total thrust at launch is 1.3 million lb., increasing to 1.5 million lb. in vacuum.
Each kerosene-fueled engine is fed via a single-shaft, dual-impeller turbopump. The fuel is also cycled to provide regenerative cooling of the thrust chamber and expansion nozzle, as well as serving as the pressurized fluid to control the thrust vector actuators.
The 227-ft. vehicle incorporates extended fuel tanks as well as improved avionics and a larger, 43 X 17-ft.-dia. payload fairing. The demo was the first SpaceX flight from space launch complex SLC-4E, a former Titan 4 pad the company is leasing from the Air Force.
Aside from the faster-than-hoped-for splashdown of the first stage, the flight was not without its share of drama. Reports based on information from SpaceTrack, a satellite tracking and space situational awareness service, indicated a larger-than-expected debris field in the orbital path of the vehicle, with up to 20 discrete objects in view. The tracking data led to speculation that the second stage may have disintegrated shortly after payload deployment.
"We have no reason to believe there was an explosion of any kind," SpaceX declared, noting that following insertion of the satellites to the correct orbit, "the Falcon 9 second stage underwent a controlled venting of propellants and the stage was successfully safed. During this process, it is possible insulation came off the fuel dome on the second stage, and is the source of what some observers incorrectly interpreted as a rupture in the second stage."
The company adds that it "will continue to review to help identify the source of the extra debris, but our data confirms there was no rupture of any kind on the second stage."

If they can test the fix on the ground, they will test a different stage first, then apply those changes to the SES-8 second stage. It's always easier to do things in the factory when you have all of the required tools and fixtures handy.

ЦитироватьSpaceX Status: Most of SpaceX's current focus is on the upcoming salvo of missions, with the second launch of their upgraded Falcon 9 v1.1 aiming to follow up the success of the Cassiope mission (http://www.nasaspaceflight.com/2013/09/spacex-debut-falcon-9-v1-1-cassiope-launch/).

 The launch vehicle – and its passenger, the SES-8 satellite (http://www.nasaspaceflight.com/2013/10/ses-8-florida-next-falcon-9-v1-1-launch/) – are both undergoing launch processing at SpaceX's SLC-40 complex. However, the launch date has since slipped to a NET (No Earlier Than) November 22 launch date, per L2′s SpaceX sectio (http://forum.nasaspaceflight.com/index.php?board=60.0)n.
Efforts into the Upper Stage re-start investigation are ongoing, following its issue during the Cassiope mission. While the Canadian satellite was successfully deployed, a re-start of the stage was attempted as part of SpaceX's fully-reusable launch vehicle aspirations (http://www.nasaspaceflight.com/2013/10/musk-plans-reusability-falcon-9-rocket/).
The relevance to the SES-8 mission is the requirement to re-start the upper stage as part of the satellite's mission profile. It is understood the stage re-starts without issue during ground testing, but may have a unique issue once in the cold vacuum of space (http://www.nasaspaceflight.com/2013/10/ses-8-florida-next-falcon-9-v1-1-launch/).
With the delay to the SES-8 mission, the prospect of the next flight of the F9 v1.1 – carrying the Thaicom-6 satellite (http://www.nasaspaceflight.com/2013/10/spacex-realign-falcon-9-missions/) – occurring just one month later are all-but gone.
A separation of 30 days between launches is understood to be a hard limit (http://www.nasaspaceflight.com/2013/10/spacex-realign-falcon-9-missions/), resulting in the Thaicom-6 mission having to avoid the holiday period and re-target for a launch in the new year.
All launch dates are subject to change, with the realigned target of November 22 for SES-8 a preliminary placeholder, subject to approval from the Eastern Range. Should approval be granted, the launch window will stretch from 13:28 to 15:28 local time, per L2.

ЦитироватьTasked with lofting the SES-8 satellite into a geostationary orbit, the launch date has slipped a few times due to work relating to an issue observed during the Cassiope mission – specifically the restart of the second stage in space.

While the restart wasn't a mission requirement for Cassiope's successful deployment, it is required for the SES-8 mission, which has the ultimate goal of reaching a GEO destination.

Z6With the Eastern Range approving a launch date target of November 22, SpaceX lined up their pre-launch tasks, with L2 information noting a Wet Dress Rehearsal (WDR) set for November, 12 – followed by the Static Fire (Hot Fire) on November 14.

However, updated L2 information has noted the WDR was "scrubbed/cancelled", allowing for it to become part of the Static Fire test. This was soon followed by the launch date moving to a preliminary date of November 25.

Reasons for the latest slip are not fully clear. However, it is understood to include working Range approval for pre-launch events surrounding the upcoming MAVEN launch and ongoing work to complete the upgrades to the SLC-40 launch site for the Falcon 9 v1.1.

  WASHINGTON — Space Exploration Technologies Corp.'s (SpaceX) first launch of a commercial telecommunications satellite will be delayed to Nov. 25 from Nov. 22, SpaceX President and Chief Operations Officer Gwynne Shotwell said Nov. 13.
"We wanted a little bit more time to make sure the launch site was ready for us, and we wanted to give the [launch vehicle] crew a little more rest," Shotwell said during a press event at NASA headquarters here.
The event was held to mark the end of NASA's Commercial Orbital Transportation Services Program, a development effort that helped fund new rockets and spacecraft from SpaceX and Orbital Sciences Corp. now being used to resupply the international space station.
Shotwell would not be more specific about the delay.
SpaceX's customer for the Florida launch is satellite fleet operator SES of Luxembourg, who is entrusting its SES-8 communications satellite to the Falcon 9 v1.1 rocket's maiden launch to geostationary transfer orbit, the drop off point for most commercial communications satellites. The launch will take place from Cape Canaveral Air Force Station's Launch Complex 40.
SpaceX has accrued a substantial backlog of commercial communications satellite launches, and a successful launch of SES-8 will open the door for the company to begin fulfilling those orders.
Falcon 9 v1.1, the latest version of the company's nine-engine Falcon 9 rocket, made its debut Sept. 29 from Vandenberg Air Force Base, Calif., when it launched the Canadian Space Agency's Cassiope space-weather satellite. On that flight, Falcon 9's upper stage failed to reignite — something it will have to do in order to get SES-8 to geostationary transfer orbit.
Meanwhile, Shotwell said work is progressing on the Falcon 9 v1.1 that will launch Thailand's Thaicom 6, another communications satellite bound for geostationary transfer orbit.
"The elements [of Falcon 9] are ready and we're going to start shipping them to the Cape right after a static fire test on Nov. 19," Shotwell said. "And we will continue to hold the Thaicom 6 launch date of Dec. 20."

ЦитироватьFrozen Igniter Marred Last Outing, SpaceX Confirms on Eve of Watershed Falcon 9 Launch
 By Peter B. de Selding | Nov. 22, 2013

"The igniter fluid lines froze after longer exposure to cold oxygen," SpaceX said of Falcon 9 v1.1's Sept. 29, 2013 debut. "This never happened on the ground because ambient air kept the lines warm. We've added insulation and made sure that cold oxygen can't impinge on the lines." Credit: SpaceX

PARIS — The Sept. 29 reignition failure of the SpaceX Falcon 9 v1.1 rocket was caused when the engine's igniter fluid lines froze following exposure to oxygen and prevented a full second burn, SpaceX and other industry officials said.
While the Sept. 29 flight completed part of its mission — delivering a Canadian research satellite into low Earth orbit — it did not complete a full qualification of its upper stage's reignition capability, which will be indispensable for the rocket's imminent entry into commercial market for geostationary-orbiting telecommunications satellites.
Nonetheless, because the reignition anomaly appears so basic, and the fix so simple — adding thermal insulation — insurance underwriters and satellite fleet operator SES of Luxembourg have agreed to proceed with the launch of the SES-8 telecommunications satellite without seeing a flight demonstration of the reignition capability.
SES-8, which is insured for $200 million, is in final preparations for a Falcon 9 v1.1 launch the week of Nov. 25 from Cape Canaveral Air Force Station, Fla. SES paid a premium of about $24 million for the policy.
Much is riding on this flight beyond SES's satellite.
SES is the world's second-largest commercial satellite fleet operator with 50-plus spacecraft in orbit. Merely replacing this capacity means the company launches three or four satellites per year. Any expansion, and SES is expanding, means more-frequent launches.
SES's three to four annual launches is part of a total global commercial market of between 20 and 25 launches per year.
A successful SES-8 mission that fully demonstrates Falcon 9's performance to geostationary transfer orbit, the destination of most telecommunications satellites, would open the commercial market to  Hawthorne, Calif.-based Space Exploration Technologies Corp. (SpaceX).
SpaceX already has a backlog of commercial launches valued at more than $1 billion, about half of which is for satellites heading to geostationary orbit. The other half is made up launches of low-orbiting spacecraft.
SpaceX Chief Executive Elon Musk said following the Sept. 29 flight that the Falcon 9 v1.1 upper stage had demonstrated its reignition capability on multiple occasions during ground tests, and that the Sept. 29 failure could simply be one of being accounting for all the conditions of the space environment.
That explanation turns out to be correct. In response to SpaceNews inquiries, SpaceX on Nov. 21 issued a statement confirming what industry officials have been saying for several weeks:
"The igniter fluid lines froze after longer exposure to cold oxygen," SpaceX said. "This never happened on the ground because ambient air kept the lines warm. We've added insulation and made sure that cold oxygen can't impinge on the lines."

We heard Elon say that the SpaceX contract with SES requires full expendable-style performance. Does this mean
that SES will be able to load more prop into its tanks? If some performance had been reserved for booster stage re-lights, would the SES-8 tanks have been only partly full? What would this do to spacecraft lifetime?

What other considerations go into this requirement as a contract consideration, as opposed to a technical necessity?

The injection orbit for SES-8 is called a super-synchronous GTO (GTO = Geosynchronous Transfer Orbit) which means that the apogee is above the GEO synchronous altitude of 35,786 km. (A satellite in a circular orbit at GEO altitude has an orbit period of 1 day, matching the Earth's rotation rate). A typical GTO (like you get off of Ariane, Land Launch, Sea Launch, and some other launchers) is an ellipse that has apogee at or near GEO altitude and perigee altitude of somewhers between a couple of hundred kilometers to a few thousand kilometers. It is then up to the satellite to use onboard thrusting to raise perigee up to GEO.

The super-synch GTO also has a fairly low perigee, but it's apogee is usually 10's of kilometers above GEO. This means the satellite's orbit has higher energy. So even though you have to now both raise perigee to GEO and lower apogee to GEO, there is still a fuel savings. For the SES-8 mission, most of the Falcon 9's performance will go into putting the spacecraft in an orbit over 80,000 km altitude at apogee. Some of the rocket's performance will also lower the orbit inclination from about 28 degrees (the lattitude of Cape Canaveral) to a little under 21 degrees, also reducing the amount of fuel that the satellite will require to get to its final orbital slot.

The SES-8 satellite's propellant tanks will be loaded as full as possible for the Falcon 9 to acheive the desired injection orbit. Again, since this is a high energy orbit, less proplellant will be required in the satellite than for a typical GTO to get the satellite to the desired orbit.

Kevin-rf - Yeah those drawings always bug me, too. The Earth is also always too big for a satellite being at GEO altitude. All I can say is artistic license does not reflect physical reality. (maybe I should add that saying to my signature  :) ).  However there are some satellites (e.g. Loral's FS-1300) which do deploy solar arrays very soon after launch and remain like that throughout the orbit raising period. But I don't know if the reflectors are deployed at that time or if they wait until the satellite gets to GEO.

LurkerSteve - 27 STAR-2's and no STAR-3's, yet. The STAR-3 will be fine on an F9. But the injection orbit won't be as high as the SES-8 or Thaicom-6 missions. It still may be able to reach super-synch, just not as high as 80,000+ km.

ЦитироватьWhat is SES-8's mission?

SES-8 will be co-located with NSS-6 at 95 degrees East to provide growth capacity over Asia and the Pacific region.

SES-8 will support the rapid growth of markets in South Asia and Indo-China through its high performance beams, as well provide expansion capacity for DTH applications and deliver SD and HD channels to the region.

SES-8
The SES-8 mission will launch the SES-8 commercial telecommunications satellite, an Orbital Sciences GEOStar-2 spacecraft.  This hybrid Ku- and Ka-band spacecraft weighs 3,138 kg (6,918 lbs) at launch. This mission will be the first Falcon 9 launch to a geosynchronous transfer orbit, delivering the satellite to a 295 x 80,000 km orbit at 20.75 degrees inclination.
 
The satellite will provide communications coverage of the South Asia and Asia Pacific regions. Co-located with NSS-6 at SES's 95 degrees East orbital slot, its high performance beams will support rapidly growing markets in South Asia and Indo-China, as well as provide expansion capacity for direct-to-home (DTH), very small aperture terminal (VSAT) and government applications. The satellite is expected to provide 5 kilowatts of power to its payload of 33 Ku-band transponders.

ЦитироватьLaunch Sequence
The launch sequence for Falcon 9 is a process of precision necessitated by the rocket's approximately one-hour launch window, dictated by the desired orbit for the satellite.  If the one-hour time window is missed, the mission will be attempted on the next day.
 
A little less than four hours before launch, the fueling process begins—liquid oxygen first, then RP-1 kerosene propellant. The plume coming off the vehicle during countdown is gaseous oxygen being vented from the tanks, which is why the liquid oxygen is topped off throughout the countdown.
 
Terminal countdown begins at T-10 minutes, at which point all systems are autonomous. The SpaceX Launch Director at the Cape Canaveral Air Force Station gives a final go for launch at T-2 minutes and 30 seconds. At T-2 minutes, the Air Force Range Control Officer confirms the physical safety of the launch area and provides the final range status. One minute before liftoff, the launch pad's water deluge system,
dubbed "Niagara," is activated.  Fifty-three water nozzles set low on the launch pad provide a curtain of water flowing at 113,500 liters (30,000 gallons) per minute.
 
Three seconds before launch, the nine Merlin engines of the first stage ignite. The rocket computer commands the launch mount to release the vehicle for flight, and at T-0 Falcon 9 lifts off, putting out 1.3 million pounds of thrust.  

Flight
The vehicle will pass through the area of maximum aerodynamic pressure—max Q—approximately 80 seconds into flight. This is the point when mechanical stress on the rocket peaks due to a combination of the rocket's velocity and resistance created by the Earth's atmosphere. 
 
Approximately 178 seconds into flight, the first-stage engines are shut down, an event known as main-engine cutoff, or MECO. Five seconds after MECO, the first and second stages will separate. Seven seconds later, the second stage's single Merlin vacuum engine ignites to begin a 5 minute, 20 second burn that brings the satellite into a parking orbit. The fairing that protects the payload is deployed early in this burn. Eighteen minutes after injection into the parking orbit, the second stage will relight for just over one minute to carry the payload to its geosynchronous transfer orbit.
 
Satellite Deployment
Approximately five minutes after the second burn (at the 32 minute, 53 second mark after launch), the SES-8 satellite is deployed into orbit.

Technicians are in the final stages of readying a SpaceX Falcon 9 rocket for launch Monday on the launcher's first mission to geostationary transfer orbit with a commercial communications satellite for television broadcasters in India and Southeast Asia.

The 224-foot-tall rocket will be rolled to the launch pad and erected vertical ahead of Monday's launch, which is set for a 66-minute launch window opening at 5:37 p.m. EST (2237 GMT) from Cape Canaveral's Complex 40.

SpaceX CEO Elon Musk says the launch will be the Falcon 9's "toughest mission to date," according to a post on his Twitter account.

"Requires coast + upper stage restart + going to 80,000 km altitude (~1/4 way to moon)," Musk wrote on Twitter.

The 6,918-pound mass of the SES 8 communications satellite gives the Falcon 9 ample performance to boost the spacecraft into a high-altitude "supersynchronous" transfer orbit. The high orbit will help SES 8 save propellant when it uses an on-board propulsion system to circularize its orbit at an altitude of 22,300 miles over the equator.

The weather forecast for Monday calls for an 80 percent chance of acceptable conditions for launch.

"Winds weaken and become more easterly through the day on Monday, decreasing below liftoff constraints by the launch window opening," Air Force meteorologists wrote in a forecast summary Saturday. "There is a low lightning threat, but coastal showers could be in the area. The primary concerns for launch day are cumulus clouds and liftoff winds."

The outlook predicts scattered cloud layers at 3,000 feet and 20,000 feet with isolated showers in the area. Winds will be out of east at 15 knots with gusts to 22 knots, and the temperature is forecasted to be 69 degrees Fahrenheit.

The forecast worsens Tuesday, with just a 30 percent chance of good weather for launch.

Ready to test the commercial mettle of the Falcon 9 rocket, SpaceX engineers are preparing to loft a television broadcasting satellite into orbit from Cape Canaveral on Monday in a mission that could usher in a new paradigm in the global launch services industry.

 With a 6,918-pound communications satellite nestled in its nose, the Falcon 9 rocket is scheduled to lift off at 5:37 p.m. EST (2237 GMT) Monday from Cape Canaveral Air Force Station, Fla.

Спойлер

The SES 8 spacecraft, built by Orbital Sciences Corp. and owned by SES of Luxembourg, will be deployed from the Falcon 9 upper stage about a half-hour later on a 15-year mission to broadcast high-definition television to homes in India, Vietnam, Thailand and other parts of Southeast Asia.
The Falcon 9's first commercial satellite launch is sure to be widely-watched by rocket and satellite operators. Officials with SpaceX and SES say that is for good reason.
"Whether or not this launch is successful, I'm confident we will certainly make it on some subsequent launch," said Elon Musk, SpaceX's CEO and chief designer, in a meeting with reporters Sunday in Cocoa Beach, Fla. "I don't want to tempt fate, but I think it's going to have a pretty significant impact on the world launch market and on the launch industry because our prices are the most competitive of any in the world."
On its website, SpaceX advertises launch costs between $56 million and $77 million for a Falcon 9 flight. That is less than SpaceX's chief competitors, the Proton and Ariane 5 rockets, which run about $100 million and $200 million per launch.
Operated and sold by the European Arianespace launch provider, Ariane 5 rockets typically launch two satellites at a time, bringing its price-per-payload in line with the Russian Proton vehicle marketed by U.S.-based International Launch Services.
"In order for the other launch companies to compete, they, therefore, will have to improve their designs and really strive to have next-generation rocket technology," Musk said. "So I think SpaceX could be a powerful forcing function for the improvement of rocket technology, not just the stuff we do ourselves, but in that we will force other rocket companies to either develop new technology that's a lot better, or they have to exit the launch market."
SES is the world's No. 2 commercial satellite operator measured by fleet size, and the firm got a deal after agreeing to be on the first Falcon 9 launch to geostationary transfer orbit, according to Martin Halliwell, SES chief technical officer.
Halliwell would not disclose what SES paid for the flight, but he said the contract value was in the lower range of the price spectrum posted on SpaceX's website.

 "This is really rocking the industry. Everybody has to look out," Halliwell said Sunday. "There are a lot of people who hope that SpaceX is going to fail. If you look towards the Ariane, if you looks towards Proton, for example, I think they are shaking in their shoes. I really do. Because if this is a success, the whole industry is going to be turned upside down. I don't mean this one particular launch, but if it now becomes the norm that this is the type of launch vehicle that is going to be provided, everybody is going to have to look to their cost space and they're going to have to change their attitude as the way to go forward."
Based in a Los Angeles suburb, SpaceX builds its rockets and engines side-by-side in a cavernous factory formerly used to build fuselages for Boeing 747 jumbo jets. Musk established the company in 2002 and has followed an ethos of vertical integration, with the vast majority of each Falcon 9 rocket built by SpaceX engineers.
Until now, SpaceX's success at undercutting the prices of its competitors in the commercial launch business has not been matched by execution, at least by launches into the types of orbits favored by communications satellite companies.
Six of SpaceX's Falcon 9 rockets have launched to date. Five of the rockets flew under the banner of a public-private partnership with NASA to develop the Dragon privately-owned cargo spacecraft to service the International Space Station, replacing some of the resupply capacity lost with the retirement of the space shuttle.
SpaceX is now making good on a $1.6 billion contract with NASA covering 12 operational cargo missions using Falcon 9 rockets and Dragon logistics carriers. Two of the flights are in the books, with the third resupply sortie set for launch Feb. 22.
But the launch of SES 8 could be SpaceX's most daunting yet.
Monday's launch will be the first time SpaceX has tried to put a satellite into a high-altitude orbit. The Falcon 9 is targeting a sweeping elliptical orbit arcing as high as 86,500 kilometers, or 53,748 miles, above Earth.
 (https://img.novosti-kosmonavtiki.ru/90617.jpg)

 The "supersynchronous" transfer orbit puts SES 8 on the way toward its final circular orbit 22,300 miles over the equator. At that altitude, orbital mechanics dictates a satellite's velocity matches the rate of Earth's rotation. Such an orbit is ideal for communications satellites because it allows users on the ground keep antennas aimed at the same spot in the sky.
The liquid-fueled engine on SES 8 will handle the rest of the maneuvers to reach the 22,300-mile-high geostationary orbit, arriving there Dec. 6 for in-orbit testing of the craft's 24 transponders before entering service in January.
Monday's launch comes with new challenges for SpaceX, which has compiled a flight history of six successful Falcon 9 launches in six tries since 2010.
All of the Falcon 9's preceding missions have carried payloads to orbits no higher than 1,000 miles. Boosting SES 8 more than 80 times higher requires two burns of the launcher's second stage engine, and SpaceX's record there is mixed.
On a Sept. 29 test launch of SpaceX's next-generation Falcon 9 - sporting upgraded engines, stretched propellant tanks, a triply redundant avionics system and a bulbous payload shroud - the launcher released its passengers into polar orbit as designed after one burn of the rocket's upper stage.
Purely as a test objective, SpaceX programmed the upper stage Merlin 1D engine to re-ignite a few minutes later, but the engine's computer controller aborted the restart.
"We always knew there was some risk with the restart, so we made sure that on the first mission a restart was not necessary for orbit insertion," Musk said. "On this mission, a restart is necessary for orbit insertion, so there is a greater bar of difficulty for this mission."
Musk said engineers found the problem was in the plumbing that feeds igniter fluid into the engine's thrust chamber. Between the Falcon 9's two upper stage burns, the fluid lines froze.
"What appeared to be the case on the last mission was that the igniter lines froze due to impingement from the liquid oxygen bleed," Musk said. "There's a liquid oxygen chill that occurs during coast, and the igniter fluid freezes at a relatively high temperature. Obviously, what we've done to correct that is to insulate those lines and ensure the liquid oxygen bleed does not impinge on the lines."

 Halliwell said SES engineers were "embedded" with the SpaceX propulsion team over the last two months, tracing the cause of the engine issue and inspecting the repair work on the upper stage assigned to the launch of SES 8.
"It's given us a real feel-good factor," Halliwell said Sunday.
The launch Monday is the first flight of the improved Falcon 9, known as version 1.1, from Florida. The Sept. 29 mission lifted off from Vandenberg Air Force Base, Calif.
According to Halliwell, the mission's insurers signed off on the launch. "We have 100 percent insurance on this one," he told CBS News in an interview Friday.
SES 8 will be stationed next to the NSS 6 satellite at 95 degrees east, expanding television broadcast programming over South Asia and Indo-China, beaming TV channels into homes for Dish TV, IPM TV and AVG, three major pay TV operators in India, Thailand and Vietnam.
SES says the region is ripe for growth, and a low-cost launch vehicle helps make the business case for pursuing emerging markets.
"We chose SpaceX and we chose to be the first commercial user for SpaceX for a certain reason," Halliwell said. "We know as we go forward into these growth markets, it's absolutely critical that we have a cost-effective and efficient way to get to orbit. That's really what SpaceX brought us."
The fresh satellite will mark the 55th spacecraft to be launched for SES.
"There's still the potential, since it's a new rocket, for something to go wrong," Musk said Sunday. "With any orbital launch, because the passing grade is 100 percent, you can't issue a recall or software patch or something. It's all or nothing. There's always some risk associated with the flight not working, so we're very appreciative that SES would place a bet on SpaceX here."

PARIS — Satellite fleet operator SES's chief technical officer on Nov. 24 gave a ringing endorsement of launch services provider SpaceX some 24 hours before SpaceX's Falcon 9 v1.1 rocket makes its first-ever attempt to place a satellite in commercial geostationary transfer orbit.
In a press briefing with SpaceX Chairman Elon Musk and SpaceX President Gwynne Shotwell, SES's Martin Halliwell went so far as to say Luxembourg-based SES's relations with Hawthorne, Calif.-based Space Exploration Technologies Corp. (SpaceX) are in some ways better than SES's relations with its traditional launch-service providers.

Спойлер

Halliwell said SpaceX opened its doors to SES following the debut flight of the Falcon 9 v1.1 rocket on Sept. 29, a mission that was designed to prove the new Falcon's ability to restart its upper stage — which will be necessary for the flight of the SES-8 satellite, now scheduled for Nov. 25.
But the upper stage failed to restart when its igniter fluid lines froze in the cold temperatures of space and by virtue of their proximity to the motor's liquid oxygen. Shotwell said the company has added thermal insulation to prevent a recurrence of the anomaly.
But she declined to delve into details of what happened, saying U.S. technology transfer regulations forbid full disclosure of the matter.
Halliwell said that SES is not worried about the Sept. 29 problem.
"We've worked extremely closely with SpaceX people to see exactly what's been done" since the Sept. 29 flight, Halliwell said. "We've had extraordinary access to the engineering work that has been done. We are confident that all the risk has been retired."
Halliwell, sounding every bit as gung-ho about SpaceX as Musk and Shotwell, said the SpaceX business model featuring launch prices that are substantially lower than the competition's will be "a game-changer" for the commercial satellite industry. "It's going to shake the industry to its roots."
SES's is the world's second-largest satellite fleet operator, with 50-plus spacecraft in orbit. Its endorsement of SpaceX has given the Falcon 9 v1.1 an added dose of credibility in a market that is not known for risk-taking.
Without mentioning either the Arianespace launch consortium of Europe, which markets the Ariane 5 rocket; or International Launch Services of the United States, which markets Russia's Proton vehicle – both regular SES suppliers – Halliwell said SpaceX has caused the established rocket providers to be "rather worried about their future and how they have organized themselves for the future."
The U.S. Air Force has tentatively agreed to let the Falcon 9 v1.1 rocket into the stable of rockets the U.S. military uses once the vehicle has completed three successful flights.
Two of the three need to be consecutive flights, Showell said. Sh said the Sept. 29 flight counts as the first of these insofar as its mission, to launch a Canadian research satellite into low Earth orbit, was a success.

ЦитироватьMusk: Falcon 9 Will Capture Market Share

November 24, 2013

With just over 24 hr. to go, Space Exploration Technologies (SpaceX) founder Elon Musk says the company's new Falcon 9 v1.1 rocket is ready to launch its first commercial payload to supersynchronous transfer orbit Nov. 25 fr om SpaceX's Launch Complex 40 at Cape Canaveral AFS, Fla.

A successful launch of the SES-8 commercial communications satellite could help SpaceX unseat United Launch Alliance (ULA), the Boeing Co.-Lockheed Martin joint venture whose Atlas V and Delta IV rockets hold a virtual monopoly on launching Pentagon, NASA and intelligence community payloads.

"We're hoping to provide a forcing function for increased competitiveness in the launch vehicle industry and potentially for improving the technology across the board," Musk stated in a pre-launch conference call with reporters Nov. 24, adding that SpaceX competitors will have to quickly catch up or risk losing "significant market share" to the Falcon 9.

Спойлер

"They are now going to need to improve their rocket technology in order to compete, and that's a good thing for the future of space," Musk says.

The launch window for the Nov. 25 mission opens at 5:37 p.m. EST, when the Falcon 9 v1.1 is expected to carry the Orbital Sciences Corp.-built SES-8 satellite to supersynchronous transfer orbit for Luxembourg-based SES, the world's second largest commercial fleet operator by revenue. A supersynchronous orbit is one wh ere the apogee is significantly greater than geosynchronous altitude.

"To have the increased apogee altitude allows us to optimize the fuel usage on the satellite and to maximize our on-orbit station-keeping fuel lifetime for the remainder of the mission," says SES Chief Technology Officer Martin Halliwell. "We've done it many, many times before."

Accurate orbital insertion of SES-8 is critical to SpaceX, which is counting on three successful Falcon 9 v1.1 missions -- including two to be launched consecutively – in order to obtain U.S. government certification to launch sensitive national security payloads.

A Sept. 29 debut of the upgraded Falcon 9 rocket from the company's new launch site at Vandenberg AFB, Calif., successfully lofted an experimental Canadian science satellite to low Earth orbit. However, frozen igniter fluid lines were to blame for the failure of an upper-stage restart of the new Merlin 1D vacuum engine during the first Falcon 9 v1.1 launch.

According to SpaceX spokeswoman Emily Shanklin, the company did not detect the fluid line problem during ground tests because "ambient air kept the lines warm." It is unclear whether thermal testing was conducted. "We've added insulation and made sure that cold oxygen can't impinge on the lines" in future missions, she says.

The failure was the result of a "pretty straightforward error," according to Barry Matsumori, vice president of commercial sales and business development. He spoke Nov. 14 at Aviation Week's A&D Programs conference in Phoenix. The additional insulation did not require requalification work, he says.

SpaceX President Gwynne Shotwell says the Sept. 29 mission still counts as the first of three required for U.S. Air Force certification. The Air Force, however, has not confirmed this and officials there say they are continuing to analyze data from the mission to determine its eligibility.

SES-8 will be followed closely by another Falcon 9 v1.1 launch to a supersynchronous transfer orbit, this time for a Bangkok-based fleet operator Thaicom.

Musk says for SES-8, SpaceX will not attempt to recover the Falcon 9 v1.1's first stage booster, as was the case during the Sept. 29 launch.

"On this mission we actually are sacrificing the ability to recover the first stage to maximize the performance margin for the SES satellite," he says. Halliwell says the company has worked closely with SpaceX to ensure the success of the SES-8 launch.

"The entry of SpaceX into the commercial market is a game changer and it's going to shake the industry to its roots," Halliwell says. The fact that SpaceX can be so cost competitive to give us the same level of performance as other launch vehicle providers is important to us. All the other launch vehicle providers are looking with great interest at this launch."

Halliwell says SES, which has booked three future satellite launches on SpaceX rockets, values the extremely close relationship the two companies have forged. "We invest a lot in our spacecraft," Halliwell says. "To have that close relationship with our launch service providers is extremely important. We've managed to develop that with SpaceX, to a greater extent than our existing launch service providers."

With a dozen launches on its manifest next year, Shotwell says the company will be looking for new launch sites and investing heavily in production capability. She says SpaceX is currently producing one vehicle per month, but that number is expected to increase to "18 per year in the next couple of quarters." By the end of 2014, she says SpaceX will produce 24 launch vehicles per year.

2030 GMT (3:30 p.m. EST)
SpaceX founder Elon Musk told reporters this afternoon that officials have signed off on the fix to resolve the problem that aborted an upper stage engine restart test on the Falcon 9's last launch in late September.
The Sept. 29 launch from Vandenberg Air Force Base in California was a success, delivering Canada's Cassiope space weather research and communications demonstration satellite into polar orbit as planned.
But SpaceX attempted to re-ignite the Falcon 9's upper stage Merlin 1D engine as a test, and the restart was aborted.
"What appeared to be the case on the last mission was that the igniter lines froze due to impingement from the liquid oxygen bleed. There's a liquid oxygen chill that occurs during coast, and the igniter fluid freezes at a relatively high temperature," Musk said. "Obviously, what we've done to correct that is to insulate those lines and ensure the liquid oxygen bleed does not impinge on the lines. We looked carefully to see if there were any other possible issues that were a near-miss that we could encounter on this flight. We could not find any. We reviewed it with the SES technical team and they seemed comfortable as well."
The launch of SES 8 requires the upper stage restart to boost the satellite into a high-altitude transfer orbit on the way to a final operating position in geostationary orbit 22,300 miles above the equator.
Martin Halliwell, chief technical officer of Luxembourg-based SES, said he was comfortable the issue is behind SpaceX.
"We believe we've retired all the risk," Halliwell said this afternoon in a meeting with media in Cocoa Beach, Fla. "We've looked at the first stage, the first stage lights up OK, works perfectly. We've looked at the second stage ... we've looked at that and we're comfortable with that.
"We've worked extremely closely with the SpaceX team and we'd like to thank them for the openness and the comaraderie they've shown us during this entire process," Halliwell said. "It's been quite extraordinary, quite honestly, very different from working with some of the other launch vehicle providers."
According to Halliwell, SES engineers analyzed data on the upper stage engine provided by SpaceX and inspected the repair work on the igniter system.
"We've had our crews crawling all around the engine space," Halliwell said. "They've been embedded with the SpaceX propulsion team ... it's given us a real feel-good factor."
In order to comply with U.S. arms trade regulations, SES had to restrict the engineering team working with SpaceX on the engine anomaly to U.S. citizens.
SpaceX said engineers from NASA and the U.S. Air Force also reviewed data from the engine. "It was not a complicated issue to fix," said Gwynne Shotwell, SpaceX's president. "We're glad we caught it on a mission wh ere we were only demonstrating that [capability]."
 
1730 GMT (12:30 p.m. EST)
 The weather forecast hasn't changed much since yesterday.
There is still an 80 percent chance of favorable weather during Monday's launch window, which opens at 5:37 p.m. EST and closes at 6:43 p.m. (2237-2343 GMT).
The primary concerns at launch time are thick clouds and cumulus clouds, according to U.S. Air Force meteorologists.
"Blustery conditions behind a cold front peak this afternoon as winds slowly swing northeasterly increasing the coastal shower threat overnight. As the front makes its way into South Florida, winds continue to weaken and turn more easterly through the day on Monday decreasing below liftoff constraints," forecasters wrote Sunday.
"There is a low lightning threat, but coastal showers could be in the area. The boundary to our south is quick to return to our area in response to a low pressure system developing in the northern Gulf of Mexico which strengthens and moves east. There is a slight chance clouds ahead of this system could encroach on the spaceport towards the end of the window so thick clouds have been added and winds removed as concerns."
Launch time conditions should be partly cloudy with scattered cloud layers at 3,000 feet, 8,000 feet and 20,000 feet. Isolated showers are possible, and the temperature is forecast to be 69 degrees Fahrenheit. Winds will be out of the east at 15 knots with gusts to 22 knots.

 The weather outlook for this evening's launch window continues to show an 80 percent chance of favorable conditions, with partly cloudy skies, breezy winds and a chance of isolated showers in the area.
The 66-minute launch window opens at 5:37 p.m. EST (2237 GMT), just after sunset at Cape Canaveral.
The outlook calls for scattered clouds at 3,000, 8,000 and 20,000 feet, winds out of the east at 15 knots gusting to 22 knots, and a launch time temperature of 69 degrees Fahrenheit.
"Easterly winds and light coastal showers will continue today, but there is a very low threat of lightning. Elsewhere, a low pressure system has developed in the Gulf of Mexico and will move rapidly east towards the Florida Panhandle. There is a slight chance that thick clouds ahead of this system could encroach on the Spaceport towards the end of the window," Air Force meteorologists wrote in a forecast issued this morning.
"Primary launch day concerns are cumulus clouds with onshore flow showers and thick clouds," forecasters said.
If today's launch is scrubbed due to weather or a technical problem, SpaceX does not plan to make another launch attempt until Thursday - Thanksgiving Day in the United States.
The Federal Aviation Administration, which grants launch licenses to commercial rocket operators, has not approved launch on Tuesday or Wednesday because those are two of the busiest travel days of the year.
The forecast Thanksgiving Day also shows an 80 percent chance of favorable weather conditions, with the only concerns being liftoff winds and cumulus clouds.  
 
1445 GMT (9:45 a.m. EST)
 SpaceX technicians rolled the Falcon 9 rocket out of its hangar and mounted the booster and its transporter-erector atop Cape Canaveral's Complex 40 launch pad overnight, plugging into electrical and propellant lines ahead of the start of the countdown today.
The 224-foot-tall rocket is one of the tallest in the world. The Falcon 9's first and second stages measure 12 feet in diameter, and the SpaceX-built payload fairing housing the SES 8 communications satellite is 17 feet in diameter (5.2 meters) and 43 feet tall.
Made of two clamshell-like halves that open and fall away about 4 minutes after liftoff, the fairing is adorned with the U.S. flag on one side and the SES corporate logo on the other side.
Today's launch marks the first flight of the upgraded Falcon 9 rocket, known as version 1.1, from Cape Canaveral after the configuration first launched from Vandenberg Air Force Base in California on Sept. 29.
In an interview in September, SpaceX CEO Elon Musk said engineers added simplicity, reliability and capacity to the previous version of the Falcon 9, which flew successfully five times.
Here is part of our story on the Falcon 9 v1.1 from September:
Musk said the redesigned Falcon 9 is the prototype for a reusable rocket SpaceX envisions could drastically reduce launch costs, decreasing the price of a Falcon 9 flight even lower than SpaceX's advertised rate, which undercuts competing rockets, such as the Russian Proton and Europe's Ariane 5 launcher.
It is this version of the Falcon 9 that SpaceX hopes will safely deliver astronauts to orbit on the way to the space station, beginning as soon as 2017.
Reliability is paramount in the launch business, and cost and schedule are right behind in a matrix of concerns for rocket buyers.
Musk said SpaceX answered these appeals, and added power and efficiency to the Falcon 9's Merlin engines to loft heftier payloads into higher orbits.
SpaceX engineers installed a triple-redundant flight computer in the Falcon 9 rocket, adding another level of confidence in the launcher's avionics. They also wrote new software for the computer, which is based on a flight-proven unit from SpaceX's Dragon cargo-carrying space station freighter.
"You could put a bullet hole in any one of the avionics boxes and it would just keep flying," Musk said.
Designers adjusted the connection points between the Falcon 9's first and second stages, replacing nine hardware interfaces and three spring-like pusher elements - pneumatic devices which ensure stage separation occurs - with three connectors with integrated pushers.
"We go from 12 things that can go wrong to three at the point of staging," Musk said.
The Falcon 9 v1.1 is powered by 10 Merlin 1D engines - nine on the first stage and one on the second stage - each generating 147,000 pounds of sea level thrust. The vacuum-rated upper stage engine, sporting a niobium nozzle to radiate engine heat, produces 161,000 pounds of thrust once out of the atmosphere.
The Merlin 1C engine, used on all five of the Falcon 9's previous missions, was capable of firing with 95,000 pounds of thrust at sea level.
Along with greater performance, the Merlin 1D is easier to manufacture thanks to high-efficiency processes, increased robotic construction and a reduced parts count, according to SpaceX's press kit.
SpaceX upgraded the propellant injection system inside the Merlin 1D, replacing two valves dedicated to fuel and oxidizer with a single unit to improve reliability and save weight.
Musk said the Merlin 1D engine weighs in at less than 1,000 pounds.
"If we don't have the world record for thrust-to-weight ratio, we're very close," Musk said.
Musk's rocket team modified the engine arrangement on the first stage, an effort he said allows engineers to remove aerodynamic manifolds around the perimeter of the rocket.
Earlier Falcon 9s featured a square "tic-tac-toe" layout of the nine first stage engines arrayed in a three-by-three pattern. The Falcon 9 v1.1 uses what SpaceX calls an "octaweb" design, with eight engines surrounding a center engine in a circular pattern.
According to Musk, engineers installed ablative bumpers between the engines to prevent a mishap with one engine from damaging another.
The first stage upgrades also include a heat shield and stretched propellant tanks for the Merlin engines' supply of kerosene and liquid oxygen.
"We put a stronger heat shield at the base of the rocket to better enable the first stage to survive the high dynamic pressure on re-entry," Musk said.
The new Falcon 9 first stage is 60 percent longer but has the same diameter as the Falcon 9's previous version, permitting the rocket to be fabricated with the same tooling already inside SpaceX's rocket factory in Hawthorne, Calif.

 We're reporting live fr om Cape Canaveral Air Force Station. Weather is still favorable for launch this evening, and there are no issues being worked at this point in the countdown.
The mission's primary payload is the 6,918-pound SES 8 communications satellite for SES of Luxembourg.
Clouds blanketed Cape Canaveral throughout the day are thinning out, but conditions are blustery with stiff winds out of the east.
          
2107 GMT (4:07 p.m. EST)
 T-minus 90 minutes. The countdown continues tracking toward an on-time liftoff at 5:37 p.m. EST (2237 GMT).
Today's launch is the second flight of SpaceX's upgraded Falcon 9 rocket, which features more powerful engines, a protective payload fairing for satellite passengers, stretched fuel tanks, and a more robust avionics system.
The upgraded rocket, known as the Falcon 9 v1.1, first launched Sept. 29 on a demonstration flight from Vandenberg Air Force Base, Calif.
All of the Falcon 9's previous launches originated from Space Launch Complex 40 at Cape Canaveral Air Force Station, Fla.
Today's flight is from Space Launch Complex 40, which was formerly used by the Air Force's Titan 4 rocket until its last flight from Florida in April 2005. SpaceX took over the pad and launched the first Falcon 9 rocket from there on June 4, 2010.
The second Falcon 9 launch on Dec. 8, 2010, sent SpaceX's first Dragon capsule into space on a two-orbit test flight for SpaceX's commercial cargo services to the space station. The December 2010 flight did not go to the space station, but it demonstrated Dragon's avionics and heat shield, culminating with splashdown in the Pacific Ocean.
SpaceX's next launch on May 22, 2012, launched the Dragon spacecraft on a NASA-sponsored test flight to the International Space Station. The 9-day Dragon mission delivered cargo to the space station and returned hardware from orbit with a splashdown in the Pacific Ocean on May 31.
On Oct. 7, 2012, SpaceX launched its fourth Falcon 9 rocket on the first operational Dragon resupply flight to the space station. The three-week mission delivered 882 pounds of cargo to the complex and returned to Earth on Oct. 28 with 1,673 pounds of equipment.
A Falcon 9 launch on March 1, 2013, put up another automated Dragon cargo craft en route to the space station with 1,869 pounds of supplies. It arrived at the outpost March 3 and stayed for 23 days before coming back to Earth with 2,668 pounds of return cargo.
The most recent Falcon 9 launch on Sept. 29 from California deployed Canada's Cassiope space weather research and communications demonstration satellite into polar orbit.
          
2000 GMT (3:00 p.m. EST)
 The Falcon 9 rocket is fully fueled with super-cold liquid oxygen and kerosene propellants. Both stages are being replenished with cryogenic oxidizer until the final minutes of the countdown to replace propellant that gradually boils off due to the warm ambient temperatures in Florida.                   
SpaceX says the webcast of today's launch will begin at 5 p.m. EST (2200 GMT), about 37 prior to liftoff, and continue through cutoff of the second stage engine.
We will have the live webcast on this page.

1940 GMT (2:40 p.m. EST)
 Everything is on schedule for today's Falcon 9 launch from Cape Canaveral Air Force Station, Fla.
Preliminary checks on the 224-foot-tall launcher are underway, and propellants are being loaded into the Falcon 9 rocket. Both stages of the Falcon 9 burn kerosene and liquid oxygen.
Check out a countdown timeline (http://www.spaceflightnow.com/falcon9/007/countdowntimeline.html) for more details on prelaunch activities

 At this point in the countdown, the SES 8 communications satellite should be transferring to internal power.         
Liquid oxygen topping continues on the Falcon 9 rocket's first and second stages.
 
2204 GMT (5:04 p.m. EST)
 See our Facebook (http://www.facebook.com/spaceflightnow) page for quick images of today's countdown to launch!
          
2157 GMT (4:57 p.m. EST)
 T-minus 40 minutes. No problems reported in the countdown. Ground systems, the launch vehicle, the SES 8 payload and the weather are all cooperating for an on-time launch this evening.
The latest weather brief showed conditions are "green" for an on-time liftoff.
          
2147 GMT (4:47 p.m. EST)
 T-minus 50 minutes. Today's launch is heading for a "supersynchronous" transfer orbit with an apogee, or high point, of 86,500 kilometers (53,748 miles) and a perigee, or low point, of 295 kilometers (183 miles).
The 6,918-pound SES 8 satellite is destined for a slot 22,300 miles above the equator in geostationary orbit at 95 degrees east longitude, where its Ku-band and Ka-band payload will beam direct-to-home television broadcasts and other services to India, Southeast Asia and surrounding regions for 15 years.
Today's mission marks the first SpaceX Falcon 9 launch with a satellite heading for a geostationary transfer orbit. Such an orbit requires two burns of the Falcon 9's upper stage Merlin 1D engine, first to place the satellite into a low-altitude parking orbit, then to raise its apogee to geostationary altitude or higher.

Цитировать2220 GMT (5:20 p.m. EST)
 T-minus 17 minutes and counting. The Falcon 9 rocket stands 224 feet tall and measures 12 feet in diameter. At liftoff, its nine Merlin 1D first stage engines will generate about 1.3 million pounds of thrust.    
 
2217 GMT (5:17 p.m. EST)
 T-minus 20 minutes and counting. The final poll of the 20-person launch team will begin at T-minus 13 minutes before the countdown enters the final phase.

ЦитироватьЧастная американская компания SpaceX отложила запуск усовершенствованной двухступенчатой ракеты Falcon-9, которая должна была вывести на орбиту первый коммерческий спутник SES-8. Запуск должен был состояться 25 ноября с космодрома на мысе Канаверал (штат Флорида) в 17:37 по местному времени (02:37 26 ноября по времени Москвы).

"Стартовое окно" было открыто в течение часа, операторы SpaceХ трижды начинали обратный отсчет, но каждый раз запуск срывался по различным причинам технического характера. Так, в последний раз проблема возникла в первой ступени ракеты и была связана с системой подачи жидкого кислорода. В следующий раз Falcon попробуют запустить на орбиту 28 ноября, передает ИТАР-ТАСС.

 Nothing stands in the way of today's Falcon 9 launch at this time, and the official weather forecast has improved with a 90 percent chance conditions will cooperate for liftoff at 5:39 p.m. EST (2239 GMT).
"A low temperature of 42 degrees F at the launch pad this morning will quickly increase to the mid-60s by noon," Air Force forecasters said. "Winds will be from the north-northeast gusting to 25 knots during the daylight hours, diminishing to 10 knots after sunset."
The only concern is that winds will exceed launch constraints, but there's just a 10 percent chance that will happen.
Weather will be blustery at launch time with a temperature of 63 degrees Fahrenheit and winds out of the north-northeast at 15 knots gusting to 22 knots.

There has not been a Thanksgiving Day launch from Cape Canaveral since 1959, when an Atlas-Able launch vehicle lifted off with the Pioneer P-3 lunar probe. The mission ended in a launch failure.

The last Thanksgiving launch from U.S. soil occurred in 1991 from Vandenberg Air Force Base in California, when an Atlas E rocket successfully lofted an Air Force weather satellite into orbit.

 Kerosene and liquid oxygen are being pumped aboard the two-stage Falcon 9 rocket. Both stages burn the mix of liquid propellants to fuel 10 Merlin 1D engines.
SpaceX says the webcast of today's launch will begin at 5 p.m. EST (2200 GMT), about 39 prior to liftoff, and continue through the first cutoff of the second stage engine about 10 minutes into the mission.

Цитировать2039 GMT (3:39 p.m. EST)
 T-minus 2 hours and counting. The Falcon 9 rocket is fully fueled with super-cold liquid oxygen and kerosene propellants. Both stages are being replenished with cryogenic oxidizer until the final minutes of the countdown to replace propellant that gradually boils off due to the warm ambient temperatures in Florida.
All weather rules are currently observed "green" for launch, and there continues to be a 90 percent of acceptable conditions during this evening's 65-minute window opening at 5:39 p.m. EST (2239 GMT).

Цитировать2139 GMT (4:39 p.m. EST)
 T-minus 60 minutes and counting. This launch was delayed from Monday after several technical problems held up the countdown, forcing a scrub.
The last glitch was in the first stage's liquid oxygen pressurization system. A SpaceX spokesperson says engineers modified the countdown sequence to eliminate the fluctuations seen during the last attempt.
The fix included improved controls for ground operators to pressurize the tank and for topping it with liquid oxygen, the spokesperson said.

ЦитироватьEngine Inspection on Tap after SpaceX Scrubs Thanksgiving Launch  
By Peter B. de Selding (http://www.spacenews.com/users/peter-b-de-selding) | Nov. 29, 2013

PARIS — SpaceX will take several days to examine the causes of a slower-than-expected increase in pressure in the Falcon 9 rocket's first stage cryogenic oxygen tank that forced a last-second scrub of  its planned Nov. 28 launch of the SES-8 telecommunications satellite.
The first of two countdown aborts occurred at T minus zero second — the moment of ignition of the first-stage engines. SpaceX had hoped to nail down the issue within the time it took to restart the countdown at T minus 13 minutes, but at T minus one minute 48 seconds decided that this countdown too should be aborted.
"We called manual abort. Better to be paranoid and wrong. Bringing rocket down to borescope engines," SpaceX Chief Executive Elon Musk tweeted after the second abort of the day.
Space Exploration Technologies Corp. (SpaceX) will now give itself " [p]robably at least a few days" to examine what happened before making another attempt, Musk said Nov. 28 via Twitter. "Depends on whether we need to pull the turbopumps." The launch will be the second of SpaceX's new Falcon 9 v1.1 rocket and the company's first attempt at placing a satellite into geostationary transfer orbit.
The Nov. 28 abort followed a Nov. 25 countdown stop, in the final few minutes before liftoff, because of an oxygen-pressurization issue.
Flight attempts from the Cape Canaveral Air Force Station, Fla., spaceport were suspended for two days, on Nov. 26 and 27, because of heavy commercial air traffic congestion on the eve of the U.S. Thanksgiving holiday.
The U.S. Federal Aviation Administration had given SpaceX authorization to fly on Nov. 28 and 29, but the company wants to give itself more time to get to the bottom of the issue. 
The mission's goal is to place the SES-8 telecommunications satellite, owned by fleet operator SES of Luxembourg, into a supersynchronous transfer orbit from which SES-8 will power its own way to final geostationary position.
SpaceX had not announced a new target launch date as of early Nov. 29.

ЦитироватьHypergolic ignition is one of the neat concepts in rocketry that don't have a great parallel in day-to-day life. It's an rare thing that would be scary if it was something that happened often. Hypergolic simply means that, when exposed to each other, two chemicals will burst into flame without a spark or other ignition source.

 The ignition process on a rocket engine is critical and must be of high reliability. On a vehicle with multiple engines, if 8 out of 9 lit but one was just dumping un-lit propellant out the end, the fire fr om the others would ignite that propellant. The fire would then travel up into the engine wh ere it would create a massive pressure spike, definitely destroying the engine and possibly destroying engines nearby. In propulsion testing the euphemism for this is a "hard start" leading to "rapid unplanned disassembly".

 SpaceX is solving the problem of absolute ignition reliability by using hypergolic ignition. They use a mix of two chemicals, triethylaluminum and triethylborane, aka TEA-TEB. Each is basically a metal atom (aluminum or boron) holding on to three hydrocarbon molecules (tri-ethyl), ready to break at a moment's notice.

 These two chemicals will spontaneously and near instantaneously burst into flame upon contact with oxygen. It can be oxygen in air or liquid oxygen in a rocket engine. The boron in the TEB is what causes the green flame when the engines start. To start the engine, LOX is flowed through the rocket injector into the chamber from the vehicle's tank, TEA-TEB is injected into the chamber to create ignition, then RP-1 (fancy kerosene) is flowed in from the vehicle tank to start burning. The flows are increased, thrust is made, and the rocket launches.

 To save weight on the first stage apparently they are flowing the TEA-TEB from a tank on the ground. Elon's tweet was "Abort was caused by oxygen in ground side TEA-TEB. Upper stage on separate internal circuit, so doesn't face same risk."

 So there was some oxygen that inadvertently got in the TEA-TEB tank. Could have just been atmospheric oxygen that got in when the tank was refilled, or could have been a bit of oxygen that flowed back in from a previous engine test. That would then react with the TEA-TEB in the tank and reduce its concentration, so that the tank then contained a mix of TEA-TEB and combustion products.

 In other words, it was like they expected 180 proof TEA-TEB but only got 100 proof. The fire in the engines was monitored and was less than the launch computer expected, so it shut the engines down rather than proceeding to full thrust.

 The other common approach for igniting restartable liquid engines is the "spark torch igniter". A spark plug ignites normal propellants in a little rocket engine, which fires into the big rocket engine. This is what most of the smaller New Space rocket companies use because working with hypergols is unpleasant. Hypergolic chemicals are expensive, usually poisonous, some are carcinogenic, and by nature any spills or contamination can result in unexpected fires.

 In theory, hypergols are more reliable. In practice, that seems to not necessarily be the case.

В итоге вывод Falcon 9 в безвоздушное пространство перенесли на День благодарения. Казалось бы — отличный повод! Но ракету SpaceX опять постигла неудача. Эксперты не успели убедиться в 100% безопасности подъема объекта в небо, поэтому изобретение скандально известного Элона Маска осталось на земле.

Что мне подсказывает, что от попадания туда кислорода давление наоборот должно повысится от горячих газообразных продуктов реакции - вплоть до взрыва.

Цитироватьif Triethylborane is strongly pyrophoric, how would it be contaminated with oxygen?

Easily  (https://img.novosti-kosmonavtiki.ru/90773.webp)
Of course, if you just expose TEA/TEB to air - it is going to be a fire. But if you lower the amount of air available by order of magnitude (or two (https://img.novosti-kosmonavtiki.ru/84445.webp) ) - there will be no fire, just a fast reaction of part of TEB with O2.
So, if you have in the TEA/TEB line a B-nut which is not tightened all the way - you have a LEAK of O2 going inside. This will spoil the igniter.
BTW, moisture (water condensate) inside these lines would have the same spoiling effect.

So, strictly speaking, "Triethylborane contaminated with oxygen" = TEB contaminated with *products* of oxidation.
This reduces pyrophoric activity.

«РТ-Химкомпозит» разработал орбитальное пусковое горючее ПГ-2

Холдинговая компания «РТ-Химкомпозит» разработала высокоэффективную технологию производства орбитального пускового горючего ПГ-2.

Предприятие «ГНИИХТЭОС», входящее в холдинг «РТ-Химкомпозит», наряду с производством продукта, проводит весь комплекс исследований по определению качественных показателей используемого сырья для его производства, а также контрольные испытания по аттестации горючего ПГ-2 и его паспортизацию.

«Мощность созданного производства пускового горючего способна обеспечить потребности космической отрасли в данном продукте», - отметил генеральный директор «РТ-Химкомпозит» Сергей Сокол.

Орбитальное пусковое горючее ПГ-2 сегодня используют ОАО «НПО «ЭНЕРГОМАШ» имени академика В.П. Глушко» (г. Химки Московской области), РКК «Энергия» (г. Королев Московской области), КБХА (г. Воронеж) и др.

Газогенератор запускается, газ поступает на турбину ТНА и через теплообменник в камеру расширения ЖРД. Обороты турбины увеличиваются, под возросшим давлением разрывается диафрагма, открывается топливный клапан и вслед за горючим в камеру сгорания входит гипергольная жидкость, которая, контактируя с окислителем, производит спонтанное воспламенение, и ЖРД начинает работать.

DELAY. Launch has been pushed back to Tuesday to allow more time to finish work on the Falcon 9 rocket.

"All known rocket anomalies resolved," SpaceX CEO Elon Musk posted on Twitter. "Will spend another day rechecking to be sure."

The launch window Tuesday is unchanged. It opens at 5:41 p.m. EST (2241 GMT) and extends 86 minutes.

The weather outlook Tuesday calls for good weather with just a 10 percent chance conditions will forbid launch.

The forecast for Tuesday predicts scattered clouds at 10,000 feet, southeast winds at 10 knots and a launch time temperature of 68 degrees Fahrenheit.
