NASA AND SPACEX AGREE DEMO-1 IS GO FOR MARCH 2
By Marcia Smith | Posted: February 22, 2019 11:59 pm ET | Last Updated: February 23, 2019 12:16 am ET
...
The outstanding issue that worries Russia is that SpaceX's Crew Dragon (or Dragon-2) does not have a separate software "box" to ensure the spacecraft will not collide with ISS if other systems fail.  Gerstenmaier explained that NASA is confident that redundant systems on the spacecraft are sufficient.  He conceded that Russia raised the issue in December, but he did not follow through with them during the 35-day partial government shutdown and hence the issue arose today.  He is certain they will agree once they have all the relevant information.
...
In fact, one takeaway from the briefing is that NASA is not looking at this simply as a test flight, but an actual mission to the ISS and the safety of the ISS crew is paramount.  This is the first Dragon spacecraft that will dock with ISS instead of berthing to it.  The cargo version of Dragon maneuvers close to ISS and then is captured by astronauts using the robotic Canadarm2 and emplaced onto a docking port by ground controllers.  Crew Dragon will dock with ISS using its own propulsion system.  It will dock to an International Docking Adapter (IDA) that was delivered to ISS on a cargo Dragon flight in 2016.  This will be the first time it is used.

NASA gives go-ahead for SpaceX commercial crew test flight
by Jeff Foust — February 22, 2019
...
He said the concern was about what would happened if there was a failure of the main computers of the spacecraft on approach, and how it would perform a "breakout" maneuver to avoid the station. He said the computers on Crew Dragon are fault tolerant, but that the mission team will "look a little more rigorously" at fault detection procedures. "I don't think it will be a problem once we go through the details of why it's safe," he said.

There are several other issues with this Crew Dragon spacecraft, said Gerstenmaier. "The vehicle is not fully qualified," he said. "But we know the hardware is good enough to go do this demonstration flight. In fact, we want it to go to flight to see if there's something else we missed, and we fully expect to learn some things on this flight."

Among those issues, he said, is with the spacecraft's Draco thrusters. Kathy Lueders, manager of NASA's commercial crew program, said a thruster failed on an earlier Dragon cargo mission. "The SpaceX folks have done a tremendous amount of testing over the last four or five months," she said, isolating to operations at very low temperatures. "We're totally avoiding that condition on this mission by controlling the operational parameters of the mission."

She added, though, that she had signed off on all the risks associated with the flight by mitigating them or concluding they were acceptable. "I feel like we've closed out all of our requirements with the space station program," she said. "I will tell you that I'm ready to fly now."

Weather Prediction: 80 Percent 'Go' for Saturday Launch

Stephanie Martin
Posted Feb 26, 2019 at 5:52 pm


SpaceX's Crew Dragon at Launch Complex 39A

SpaceX is set to launch its Crew Dragon spacecraft on a Falcon 9 rocket, the first launch of a space system designed for humans built and operated by a commercial company through a public-private partnership, on a flight test to the International Space Station (ISS) at 2:49 a.m. EST on Saturday, March 2.

For a launch Saturday, meteorologists with the U.S. Air Force 45th Space Wing are predicting an 80 percent chance of favorable weather. Weak high pressure in advance of a front moving southeast into the area is expected during the launch window with a low probability for rain and weak surface winds and only slight concerns of any cumulus cloud or thick cloud rule violations during the instantaneous launch window.

Forecasters expect good weather for Crew Dragon test launch Saturday
February 26, 2019 | Stephen Clark

The first official launch weather outlook issued Tuesday by U.S. Air Force meteorologists predicts an 80 percent chance of favorable conditions for the predawn liftoff Saturday of SpaceX's Crew Dragon spacecraft on a test flight to the International Space Station.

The weather outlook for Saturday's launch calls for partly cloudy skies, breezy winds from the west-southwest, and mild temperatures. The only slight concern is with potential violations of the cumulus cloud and thick cloud launch weather rules.

Liftoff of the human-rated capsule — flying without astronauts this time — is scheduled for 2:49:03 a.m. EST (0749:03 GMT), roughly the moment the Earth's rotation brings launch pad 39A at the Kennedy Space Center under the space station's orbital path.

Mission managers could adjust the launch time by a few seconds in the coming days based on updated tracking of the space station's orbit. The precise launch time Saturday will enable the Crew Dragon spacecraft to reach the orbiting research complex for an automated docking at 6 a.m. EST (1100 GMT) Sunday.

"Relatively dry southwesterly flow will keep rain probabilities low, with surface winds relatively weak," forecasters from the Air Force's 45th Weather Squadron wrote in an outlook issued Tuesday. "The forecast yields only slight concerns of any cumulus cloud or thick cloud rule violations during the primary launch window on Saturday. Maximum upper-level winds will be from the west near 80 knots at 45,000 feet."

Officials from NASA and SpaceX will convene a launch readiness review Wednesday to discuss the status of launch preparations. If managers clear the Crew Dragon spacecraft and its Falcon 9 launcher for liftoff Saturday, the rocket is scheduled to roll out of SpaceX's hangar at pad 39A some time Thursday for the trip up the ramp to the launch mount.

An erector will raise the Falcon 9 rocket vertical for final servicing and countdown preparations.

With a good weather forecast, officials are hopeful the rocket can take off early Saturday. Backup launch opportunities are available March 5 and March 9, when the space station's position in its orbit would allow the Crew Dragon to reach the outpost the day after launch. Then the Crew Dragon demonstration flight would have to stand down until after the launch of a three-person space station crew March 14 from Kazakhstan aboard a Russian Soyuz rocket.

A long-range forecast predicts a wetter weather pattern early next week, and forecasters expect a 40 percent probability of conditions preventing a launch attempt on the backup opportunity March 5.

Assuming an on-time launch and docking this weekend, the Crew Dragon spacecraft will depart the space station March 8 and return to a parachute-assisted splashdown in the Atlantic Ocean around 240 miles (390 kilometers) east of Cape Canaveral. A newly-outfitted recovery ship, with hardware and experts to secure the Crew Dragon after it returns to Earth, will retrieve the capsule and bring it back to port.

Спойлер

The upcoming Crew Dragon test flight is a major checkout of SpaceX's human-rated spacecraft, which the company developed in partnership with NASA. The U.S. space agency has a $2.6 billion contract with SpaceX to fund the design, development and testing of the Crew Dragon spacecraft.

NASA has a similar contract worth $4.2 billion with Boeing, which is developing its CST-100 Starliner crew capsule, giving U.S. astronauts two transportation providers to low Earth orbit, and ending NASA's reliance on Russian Soyuz vehicles for the job.

Following the unpiloted test flight, SpaceX will refurbish and refuel the same Crew Dragon vehicle for an in-flight abort test this spring. The abort demonstration will verify the spacecraft can fire its escape thrusters to fly away from a failing booster in flight.

Then a new Crew Dragon vehicle will be prepared for launch with a two-man team of NASA astronauts as soon as July. NASA shuttle veterans Robert Behnken and Doug Hurley will fly the Crew Dragon to the space station on a second test flight — known as Demo-2 — before the commercial spaceship is certified to begin regular crew rotation flights to the research outpost.

The SpaceX Falcon 9 rocket carrying the company's Crew Dragon (although without astronauts on this mission) on its Demo-1 flight test to the International Space Station will lift off fr om the same historic site wh ere astronauts first launched to the moon. Launch Complex 39A at NASA's Kennedy Space Center in Florida is also the site of dozens of space shuttle launches that helped build the orbital laboratory.

Launch Complexes 39A and B were constructed in the 1960s. Both launch pads have a long history of supporting launches for the Apollo and Space Shuttle Programs. Launch Pad 39A was the launch site for 11 Saturn V Apollo missions, including Apollo 11, the first Moon landing. The pad also was the launch site for 82 space shuttle missions, including STS-1, the first shuttle launch, the STS-125 final servicing mission for the Hubble Space Telescope, and STS-135, the final shuttle mission.

After the space shuttle was retired in 2011, NASA began the process to transform Kennedy Space Center from a historically government-only launch facility into a multi-user spaceport for both government and commercial use. On April 14, 2014, the agency signed a property agreement with SpaceX of Hawthorne, California, for use of the launch site for the next 20 years.

SpaceX upgraded and modified the launch pad to support its Falcon 9 and Falcon Heavy rockets. The company also built a horizontal processing hangar at the base of the pad to perform final vehicle integration prior to flight. The first SpaceX launch from the pad was the company's 10th commercial resupply services (CRS-10) mission for NASA. A SpaceX Falcon 9 launched a Dragon cargo spacecraft on CRS-10 on Feb. 19, 2017. The Dragon delivered about 5,500 pounds of supplies to the space station, including the Stratospheric Aerosol and Gas Experiment (SAGE) III instrument to further study ozone in the Earth's atmosphere. NASA and SpaceX combined have launched more than 100 missions from Pad 39A.

Because of NASA's partnership with SpaceX within the agency's Commercial Crew Program, Launch Complex 39A will once again be the site of crewed missions to the space station.

NASA also is partnered with Boeing to return crewed missions to the space station; the company will launch its CST-100 Starliner spacecraft on a United Launch Alliance Atlas V rocket a few miles down the shoreline, from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

By relying on industry trips to low-Earth orbit, NASA can concentrate on developing rockets and spacecraft for missions to the Moon and Mars.

Weather Forecast Remains 80 Percent 'Go'; Prelaunch Briefing Set for Thursday

Anna Heiney
Posted Feb 27, 2019 at 1:13 pm

Three days remain until the planned liftoff of a SpaceX Crew Dragon spacecraft on the company's Falcon 9 rocket—the first launch of a commercially built and operated American spacecraft and space system designed for humans. Liftoff is targeted for 2:49 a.m. EST on Saturday, March 2, from Launch Complex 39A at the agency's Kennedy Space Center in Florida. The Demo-1 mission to the International Space Station serves as an end-to-end test of the system's capabilities.

The launch weather forecast continues to look promising; meteorologists with the U.S. Air Force 45th Space Wing predict an 80 percent chance of favorable weather at launch time. Thick clouds or cumulus clouds that would violate launch requirements are the primary weather concerns.

NASA will host a prelaunch briefing at Kennedy at 4 p.m. EST on Thursday, Feb. 28. The briefing will be broadcast live on NASA TV. See the full briefings and events schedule, including briefing participants, at https://go.nasa.gov/2GBCB5A.

SpaceX
Demo-1

SpaceX will launch a crew capable Dragon, known as Crew Dragon, on a test mission to the International Space Station. There will be no crew aboard, but the Dragon will dock autonomously to the station. The objectives of this mission are to demonstrate most of the capabilities of their crew transportation system. 

Demo-1 Mission Objectives:
• Demonstrate on-orbit operation of the avionics system, docking system, communications/telemetry systems, environmental control systems (pressure, thermal, humidity, etc.), solar arrays and electrical power systems and the propulsion systems • Demonstrate performance of the Guidance, Navigation and Control systems of the Falcon 9 and Crew Dragon through ascent, on-orbit, and entry • Determine acoustic and vibration levels, and loads across the Crew Dragon exterior and interior • Demonstrate launch escape trigger monitoring • Demonstrate end-to-end operations performance 

Major highlights include, but are not limited to: 

The Launch Pad:
They will lift-off from Launch Complex 39A (LC-39A) which has been greatly modified to accommodate their rocket's and spacecraft's unique requirements and operations. This includes a hangar for horizontal assembly, a new crew access arm, and a number of new rocket servicing equipment unique to Falcon 9.

The Rocket:
Falcon 9 – Block 5, which includes an updated and improved Merlin 1D Engine. SpaceX has evolved its Falcon 9 rocket over the years, incorporating incremental improvements until the current Block 5 version designed for crew missions, including improved thrust and densified propellants. 

The Spacecraft:
Crew Dragon is longer and heavier than its cargo predecessor as it needs to safely accommodate four astronauts to and from the space station. This first demonstration mission is autonomous with cargo and mass simulators to help collect data such as loads, accelerations, vibrations temperatures and pressures all over the spacecraft – inside and out. This data will provide designers with the data they need to validate that this spaceship can do the job it was designed to do. One of the key new items on Crew Dragon is the addition of eight SuperDraco abort engines, which give the spacecraft a capability it never had before: escaping an unlikely emergency situation on the launch pad or during ascent. 

Operations:
Often overlooked, pre-flight processing, launch, mission in-flight, landing and recovery operations are all as integral to safe space missions as the hardware that is used. SpaceX flight controllers, sometimes called ground operators, have control of the vehicle from countdown to recovery – with NASA keeping a watchful eye. The Crew Dragon will actually dock with the station, while the cargo Dragon would be grappled by the space station's robotic arms, all Crew Dragon missions will completely autonomously dock and undock, with crew intervention capability to manually fly, if needed. 

Re-entry and Landing:
After undocking and re-entry, Crew Dragon will utilize four parachutes to gently touch down in the Atlantic Ocean and be recovered by a brand-new recovery vessel. SpaceX is required to get the crew and spacecraft out of the water in less than an hour after splashdown.

Filled with about 400 pounds of crew supplies and equipment, Dragon will remain docked with space station for five days. 

RETURN FLIGHT
Crew Dragon will autonomously undock with the International Space Station on Friday, March 8 at approximately 2:30 a.m. EST. About five hours after Dragon departs the space station it will conduct its deorbit burn, which lasts up to 15 minutes. It takes about 35 to 40 minutes for Dragon to re-enter the Earth's atmosphere and splash down in the Atlantic Ocean, which is currently targeted for approximately 8:45 a.m. EST. Crew Dragon will utilize an enhanced parachute system, including four main chutes, to gently land in the Atlantic Ocean before being recovered and returned to Port Canaveral, Florida.
