The Northrop Grumman Antares rocket, with Cygnus resupply spacecraft onboard, launches from Pad-0A, Saturday, Feb. 15, 2020 at NASA’s Wallops Flight Facility in Virginia.

The solar arrays have successfully deployed on Northrop Grumman’s Cygnus spacecraft that is on its way to deliver approximately 7,500 pounds of science and research, crew supplies, and hardware to the International Space Station. This is the company’s 13th contracted cargo resupply mission with NASA.

Cygnus is scheduled to arrive at the International Space Station at approximately 4:05 a.m. EST on Tuesday, Feb. 18. NASA TV coverage of the spacecraft’s approach and arrival to the orbiting laboratory will begin at 2:30 a.m. on NASA Television and the agency’s website. NASA Flight Engineer Andrew Morgan will grapple Cygnus and NASA astronaut Jessica Meir  will be acting as a backup. After capture, the spacecraft will be installed on the Unity module’s Earth-facing port. NASA TV coverage of the spacecraft’s installation will begin at 6 a.m. EST.

Liftoff of Antares Rocket and Cygnus Spacecraft!

Northrop Grumman’s Cygnus resupply spacecraft is on its way to the station with about 7,500 pounds of science investigations and cargo after launching at 3:21 p.m. EST on Saturday, Feb. 15, from NASA’s Wallops Flight Facility in Virginia. At the time of liftoff, the International Space Station was flying 258 statute miles over the western Pacific, northeast of the Northern Mariana Island.

The spacecraft launched on an Antares rocket from the Virginia Mid-Atlantic Regional Spaceport’s Pad-0A at Wallops.

Northrop Grumman named the NG CRS-13 Cygnus spacecraft after former astronaut Robert Henry Lawrence Jr. Major Lawrence was selected in honor of his prominent place in history as the first African American astronaut.

This is Northrop Grumman’s 13th cargo flight to the space station and will support dozens of new and existing investigations.
