Orbital ATK successfully launched their Cygnus spacecraft towards the International Space Station this morning. The spacecraft named J.R. Thompon is carrying 7,385 lbs of cargo to the station and is scheduled to be captured on Thursday by the stations Canadarm 2. As with the previous Cygnus launches the spacecraft was given a name this time “J.R. Thompson”
S.S. J.R. Thompson
For each CRS mission, it is a tradition at Orbital ATK to name the Cygnus cargo spacecraft for an individual who has furthered our nation’s human spaceflight programs. For our OA-9 mission, we are proud to announce that the OA-9 spacecraft will be named after J.R. Thompson, a distinguished leader in the aerospace industry and a member of our Orbital ATK family. Throughout his life, J.R. held prominent positions at NASA, the Marshall Space Flight Center, and Orbital Sciences. We are honored to celebrate his life with the upcoming launch of the S.S. J.R. Thompson.
The launch was originally scheduled to liftoff on Sunday 20th but was delayed a day to allow the teams additional time to perform inspections and tests of the system to ensure a successful launch today.
This was the first launch for Orbital ATK this year, the 8th overall for the Antares rocket and the 10th for the Cygnus spacecraft. After the Orb-3 launch failure in October 2014, Orbital launched two Cygnus spacecraft on United Launch Alliances Atlas V.
Following a one day delay, due to a wayward plane during the countdown yesterday, Orbital ATK successfully launched their Cygnus spacecraft, S.S. Gene Cernan today for an International Space Station rendezvous on Tuesday.
This was the second Cygnus launch on the companies own Antares 230 vehicle, which uses the Russia RD-181 engines. This was the seventh launch of Antares with six successfully completing their missions and one failure. That failure led to the redesign of the Antares rocket which caused a two-year delay in launches, during that time Orbital made use of United Launch Alliances Atlas V to launch Cygnus to the ISS.
This morning at 11:14 AM EDT United Launch Alliance (ULA) successfully launched another Orbital ATK Cygnus spacecraft towards the International Space Station (ISS). This was the third Cygnus that ULA has launched for Orbital and at the present time the last.
Named after the late John Glenn, former Astronaut and US Senator who passed away last December. The launch was delayed several times to allow ULA time to address some issues with the launch vehicle and pad, and then to accommodate the hectic ISS schedule. The vehicle is carrying 3,459 kg (7,626 lb) of cargo to the space station and will spend at least 80 days at the station before being released. After it is successfully completed its mission another of the Saffire experiments will be performed, where a controlled fire will lite. Once that is complete the vehicle will burn up in the atmosphere.
The countdown proceeded smoothly this morning with an on-time launch, which concluded when the Cygnus spacecraft was delivered to orbit.
This was ULA’s 71st Atlas V, 36th 401 config, 4th launch of 2017 and 119th consecutive successful launch keeping their perfect 100% record.
As a side note, this was the last launch for NASA PAO George Diller who has been the voice of NASA for many launches in the past. We hope that he has a great and long retirement and will miss hearing his commentary.
Last night United Launch Alliance (ULA) launched an Orbital ATK Cygnus spacecraft towards the International Space Station (ISS). This is the second Cygnus that has launched on an Atlas V rocket and will be the heaviest payload the Atlas V has ever launched. Even with the heavier payload ULA didn’t require any Solid Rocket Boosters as Cygnus is only launching to Low Earth Orbit.
Continuing in the tradition of previous Cygnus launches Orbital ATK named this vehicle the S.S. Rick Husband in honor of Col. Rock Husband USAF.
Update: After the launch a number of people noticed that the burn time on the Centaur upper stage was almost a minute longer than originally planned. ULA has since announced that this was caused by the first stage RD-180 engine shutting down 5 seconds earlier than originally planned requiring the Centaur to compensate for the difference. They are investigating why the engine shutdown early and don’t currently know if this could impact the next Atlas V launch.
More than a year after the catastrophic failure of the Antares Launch vehicle which resulted in the lose of the Cygnus Cargo vehicle and its payload Orbital’s enhanced Cygnus vehicle lifted off from Cape Canaveral today with the help of an United Launch Alliance Atlas V rocket. The launch which was delayed three times due to inclement weather finally lifted off this afternoon when the Atlas V RD-180 came to life.
Orbital elected to purchase two Atlas V launches to allow it to resume its Commercial Resupply contract with NASA for the International Space Station while the enhancements to its Antares rocket continue. Orbital were also able to introduce there enhanced Cygnus vehicle which can carry an additional 1,200-1,500 kg of cargo depending on launch vehicle.
