Editor’s Note: This advisory was updated on April 16 to reflect changes to the time of the What’s on Board science briefing, the briefing participants, and the weight of the Cygnus spacecraft.
NASA’s commercial partner Northrop Grumman is scheduled to launch its Antares rocket carrying its Cygnus cargo spacecraft to the international Space Station at 4:46 p.m. EDT Wednesday, April 17. The launch, as well as briefings preceding and following liftoff, will air live on NASA Television and the agency’s website.
Loaded with 7,600 pounds of research, crew supplies and hardware, this Northrop Grumman’s 11th commercial resupply NASA-contracted mission. It will launch from Virginia Space’s Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility.
About two-and-a-half hours after launch, an automated command will initiate deployment of the spacecraft’s solar arrays. Full deployment will take approximately 30 minutes.
The Cygnus spacecraft, dubbed the SS Roger Chaffee, will arrive at the space station Friday, April 19. At about 5:30 a.m., Expedition 59 NASA astronaut Anne McClain will grapple the spacecraft using the station’s robotic arm. She will be backed up by David Saint-Jacques of the Canadian Space Agency. NASA astronaut Nick Hague will monitor Cygnus systems during its approach. After capture, ground controllers will command the station’s arm to rotate and install Cygnus on the bottom of the station’s Unity module.

Media registration for the launch and associated activities is closed. However, media may participate via phone in the What’s on Board briefing and prelaunch and postlaunch news conferences. Media interested in participating must contact Gina Anderson at gina.n.anderson@nasa.gov for call details.
Media already registered to attend launch activities at Wallops can get more information on schedules, facility hours of operation, remote camera setup, and more at:
The Cygnus spacecraft is scheduled to remain at the space station until July 23, when it will depart, deploy NanoRacks customer CubeSats, and then have an extended mission in orbit until December before it will dispose of several tons of trash during a scheduled fiery reentry and destruction in Earth’s atmosphere.
This will be the final mission under Northrop Grumman’s Commercial Resupply Services (CRS-1) contract with NASA before starting the CRS-2 contract missions this fall. Under Northrop Grumman’s contract, the company will fly 11 missions.
