The Antares rocket is now undergoing final assembly and testing at Wallops Island, while the Cygnus spacecraft is being prepared for shipment from Orbital's Dulles, VA production facilities to the Wallops launch site in September. The Orb-3 flight is expected to deliver its heaviest cargo manifest yet, with 5,050 pounds (2,290 kilograms) of cargo and payloads to be sent to the ISS.
ЦитатаISS Commercial Resupply Services Mission (Orb-3)Launch Date: No Earlier Than October 20, 2014Launch Site: MARS Pad 0A at NASA Wallops Flight Facility, Wallops Island, VAMission InfoLaunch Site: MARS Pad 0AAntares Launch Sequence: Approximately 10 minutesCygnus ISS Rendezvous: Targeted October 25Cygnus Stay at ISS: Approximately five weeksMission Overview An Antares rocket carrying Orbital's Cygnus cargo logistics spacecraft is scheduled to lift-off from Pad-0A at the Mid-Atlantic Regional Spaceport at Wallops Island, Virginia no earlier than October 20, 2014. Targeted launch time on October 20 is 9:29PM (Eastern). Antares will boost Cygnus to its initial target orbit, from which Cygnus will use its on-board thrusters to raise its orbit to rendezvous and berth with the International Space Station (ISS) approximately 3 days after launch. For this mission Cygnus will carry approximately 2,290 kg (5,050 lbs.) of cargo to the ISS for NASA.Orb-3 is the fourth Cygnus cargo mission to the ISS and the fifth Antares launch in the last 18 months.About AntaresThe two-stage Antares space launch vehicle utilizes a liquid-fueled first stage powered by two Aerojet Rocketdyne AJ26 engines and a solid motor ATK CASTOR 30XL upper stage to boost Cygnus into orbit. The powered launch sequence will last about ten minutes from liftoff through the separation of Cygnus from the launch vehicle. This mission is the first to use the larger, more powerful CASTOR 30XL second stage motor.Cygnus Mission DescriptionAfter separation from Antares, Cygnus will deploy its solar arrays and undergo initial check-out. The spacecraft will conduct a series of thruster burns to raise its orbit to bring it within 4 km of the ISS prior to receiving authorization to autonomously rendezvous with the station. When the vehicle approaches to within 12 meters, the astronauts will use the station's robotic arm to grapple Cygnus and berth it to the Harmony node of the station. Cygnus is planned to remain berthed at the ISS for approximately five weeks during which time the station crew will load Cygnus with materials for disposal. At the end of the mission Cygnus will depart the station and reenter the Earth's atmosphere.Viewing the LaunchThe Orb-3 launch will be broadcast on NASA TV and webcast on www.nasa.gov on launch day. In addition, NASA TV will provide live coverage of the rendezvous and berthing of Cygnus with the ISS.You can follow the launch on Twitter @orbitalsciences and on Facebook.
ЦитатаDue to the impending arrival of Hurricane Gonzalo on the island of Bermuda, where an essential tracking site used to ensure public safety during Antares launches is located, the previously announced "no earlier than" (NET) launch date of October 24 for the Orb-3 CRS mission to the International Space Station for NASA is no longer feasible.Once the hurricane has passed Bermuda, a team from NASA's Wallops Flight Facility Range will return to the tracking site to assess the situation and begin the process of re-enabling the site's functionality to support the launch.Today, Orbital and NASA together established a NET October 27 for the launch of the Orb-3 mission from the Mid-Atlantic Regional Spaceport at NASA Wallops. However, depending on the impact of the storm on Bermuda's essential infrastructure systems such as transportation, power and communications, the launch date could be moved later. The launch schedule has been established in order to build flexibility into the overall mission schedule.For an October 27 launch, lift-off time of the Antares rocket is targeted for 6:44 p.m. (EDT). The rendezvous and berthing of Cygnus with the ISS remains on November 2, with grapple of the spacecraft by the station's robotic arm at approximately 4:58 a.m. (EST).

The mission will originate from the Mid-Atlantic Regional Spaceport (MARS) at NASA's Wallops Flight Facility in eastern Virginia. Lift-off of the Antares rocket is scheduled for 6:45 p.m. (EDT), with rendezvous and berthing with the ISS early in the morning on November 2. Taking advantage of Cygnus' operational capabilities, Orbital is launching the Orb-3 mission to orbit several days earlier than necessary to preserve schedule flexibility and time its arrival at the station to conform to other visiting vehicle operations. The Cygnus spacecraft is fully fueled and loaded with most of its cargo bound for the ISS and has been mated with the Antares rocket that will launch it into low-Earth orbit. The remaining time sensitive "final load" cargo will be placed onboard tomorrow, prior to fairing encapsulation, which is also scheduled for tomorrow. On Friday, October 24, the Antares rocket will be rolled out from the Horizontal Integration Facility to the MARS launch pad 0A located about a mile away. Orb-3 Cygnus Spacecraft Named for Deke SlaytonA decorated U.S. Air Force pilot and NASA astronaut, the late Donald "Deke" K. Slayton was a champion of America's commercial space program. To salute Slayton's significant contributions to American leadership in space, Orbital has named the Cygnus spacecraft for the Orb-3 mission the SS Deke Slayton. More information about Deke Slayton is available here.Viewing the LaunchWeather permitting, the launch of Antares from Wallops Island, VA on October 27, 2014 may be visible along the East Coast. The Maximum Elevation Map shows the maximum elevation (degrees above the horizon) that Antares will reach depending on your location. The further away you are from the launch site, the closer to the horizon the rocket will be. If you are in Washington, DC the highest point Antares will reach is approximately 10 degrees above the horizon. The contours shown stop below 5 degrees. It is unlikely that you'll be able to view the rocket when it is below 5 degrees due to buildings, vegetation, and other terrain features.Time of First Sighting Map shows the rough time at which you can first expect to see Antares after it is launched. It represents the time at which the rocket will reach 5 degrees above the horizon and varies depending on your location. Using this map when observing from Washington, DC shows that Antares will reach 5 degrees above the horizon approximately 90 seconds after launch (L + 90 sec).Maximum Elevation MapFirst Sighting MapThe Orb-3 launch will be broadcast on NASA TV and webcast on www.nasa.gov on launch day.

It will also be the fourth cargo delivery mission to the ISS by a Cygnus spacecraft, including the 2013 demonstration flight. For Orb-3, Orbital will deliver its largest load of cargo to date, carrying approximately 5,050 pounds (2,290 kilograms) of cargo to the ISS for NASA. At the conclusion of the Orb-3 mission, the company will have carried a total of 13,378 pounds (6,078 kilograms) of essential supplies, equipment and scientific experiments to the ISS and will have removed 13,444 pounds (6,097 kilograms) of disposal cargo, a vital capability for the maintenance and operation of the Station.About AntaresThe two-stage Antares space launch vehicle utilizes a liquid-fueled first stage powered by two Aerojet Rocketdyne AJ26 engines and a solid motor ATK CASTOR 30XL upper stage to boost Cygnus into orbit. The powered launch sequence will last about nine-and-a-half minutes from liftoff through the separation of Cygnus from the launch vehicle. This mission is the first to use the larger, more powerful CASTOR 30XL second stage motor.Cygnus Mission DescriptionAfter separation from Antares, Cygnus will deploy its solar arrays and undergo initial check-out. The spacecraft will conduct a series of thruster burns to raise its orbit to bring it within 4 km of the ISS prior to receiving authorization to autonomously rendezvous with the station. When the vehicle approaches to within 12 meters, the astronauts will use the station's robotic arm to grapple Cygnus and berth it to the Harmony node of the station. Cygnus is planned to remain berthed at the ISS for approximately five weeks during which time the station crew will load Cygnus with materials for disposal. At the end of the mission Cygnus will depart the station and reenter the Earth's atmosphere. Image GalleryAn image gallery with photos of the launch campaign is available here. About Commercial Resupply ServicesUnder a $1.9 billion CRS contract with NASA, Orbital will use Antares and Cygnus to deliver up to 44,000 pounds (20,000 kilograms) of cargo to the ISS over eight missions, including the mission currently underway, through late 2016. For these missions, NASA will manifest a variety of essential items based on ISS program needs, including food, clothing, crew supplies, spare parts and equipment, and scientific experiments.

ЦитатаOrbital Sciences cleared for final Antares launch prepsBY STEPHEN CLARKSPACEFLIGHT NOWPosted: October 22, 2014Orbital Sciences Corp. is set to launch its next commercial resupply flight to the International Space Station on Monday after inspections revealed a rocket tracking station in Bermuda weathered a direct hit from Hurricane Gonzalo last week. Liftoff of Orbital's third commercial cargo flight to the orbiting research laboratory is set for 6:45 p.m. EDT (2245 GMT) Monday from launch pad 0A at the Mid-Atlantic Regional Spaceport at Wallops Island, Va. A two-stage Antares launcher -- with Orbital's Cygnus cargo carrier enshrouded in its nose -- is scheduled for rollout from a horizontal rocket integration hangar to pad 0A on Friday, officials said Wednesday. The Antares rocket will ride horizontally on a self-propelled mobile transporter for the one-mile trip from the horizontal integration facility to the launch pad. Hydraulic pistons will rotate the Antares booster and Cygnus cargo craft vertical on top of the pad's launch mount, and technicians will make final electrical and fluid connections between the rocket and the launch pad. "The Cygnus spacecraft is fully fueled and loaded with most of its cargo bound for the ISS and has been mated with the Antares rocket that will launch it into low Earth orbit," Orbital Sciences said in an upd ate Wednesday. "The remaining time-sensitive 'final load' cargo will be placed onboard tomorrow, prior to fairing encapsulation, which is also scheduled for tomorrow (Thursday)." The launch was delayed from Friday as Hurricane Gonzalo approached Bermuda, the home of a tracking facility required to receive telemetry from the Antares rocket as it accelerates into orbit over the Atlantic Ocean. Hurricane Gonzalo's eye passed over Bermuda late Oct. 17 as a Category 2 storm, bringing damaging winds, battering waves and heavy rains to the British island territory. Workers secured the communications equipment before the hurricane's arrival and returned this week to bring the tracking station back online. Hurricane Gonzalo churns in the Atlantic Ocean on Oct. 16 as seen from the International Space Station. Credit: NASA Orbital and NASA set Monday as the target launch date for the cargo mission after an inspection of the Bermuda tracking station. The automated Cygnus supply ship will separate from the Antares rocket's second stage about 10 minutes after liftoff, deploy its electricity-generating solar panels and begin a series of thruster burns to catch up with the space station. Officials opted to schedule the Antares launch earlier than necessary for the Cygnus spacecraft's Nov. 2 docking opportunity, choosing to give the launch team multiple launch attempts and still preserve an on-time arrival at the space station. The Cygnus spacecraft will approach the football field-sized station Nov. 2, carefully flying within 30 feet of the complex as astronauts take control of the lab's robotic arm to reach out and capture the cargo capsule. A Russian Progress supply ship is se t for launch Oct. 29 from the Baikonur Cosmodrome in Kazakhstan, with docking to the space station expected about six hours later, precluding Orbital's cargo capsule from getting to the complex within two days of launch -- the normal schedule for logistics flights operated by Orbital Sciences and SpaceX. The flight is Orbital's third logistics mission to the space station. Known as Orb-3, the mission follows Orbital Sciences cargo launches in January and July, and a test flight to the station in 2013. The company has five more resupply flights under contract with NASA. The Orb-3 Cygnus spacecraft -- dubbed the SS Deke Slayton after the Mercury astronaut and a trailblazer in commercial spaceflight -- will carry about 5,050 pounds of experiments, supplies, food and other cargo to the space station. It will stay attached to the space station until early December, when it will depart and drop back into Earth's atmosphere to burn up and dispose of trash. The Oct. 27 launch will incorporate an upgraded Castor 30XL upper stage on the Antares rocket, giving the launcher a capability to lift heavier spacecraft -- and more space station-bound cargo -- into orbit. Built by ATK, the solid-fueled Castor 30XL motor is longer than the Castor 30 stages flown on the Antares rocket's four previous missions, allowing Orbital to carry up more than 1,000 extra pounds of cargo to the space station. Orbital plans to introduce enhancements to its Cygnus spacecraft on the company's next resupply flight next spring, including a larger cargo module, a new circular solar array design, and lighter structural materials. The upgrades will allow Cygnus to haul nearly three tons of supplies to the space station. Follow Stephen Clark on Twitter: @StephenClark1.
