Nearly three months after delivering several tons of scientific experiments and supplies to the International Space Station, Northrop Grumman’s autonomous Cygnus cargo craft is scheduled to depart the International Space Station on Monday, May 11.

Live coverage of the spacecraft’s release will air on NASA Television and the agency’s website beginning at 11:45 a.m. EDT, with release scheduled for 12:08 p.m.

Flight controllers on the ground will send commands to robotically detach Cygnus from the Earth-facing port of the Unity module, maneuver it into place, and release it from the Canadarm2 robotic arm. Station commander Christopher Cassidy of NASA will monitor Cygnus’ systems as it moves away from the orbiting laboratory.

Dubbed the “SS Robert H. Lawrence,” Cygnus arrived at the station Feb. 18 for the company’s 13th cargo mission with about 7,500 pounds of supplies and science experiments ranging from research with cell cultures and bone loss to demonstration of a new miniature scanning electron microscope (SEM) with spectroscopy. Cygnus launched on Northrop Grumman’s Antares rocket from NASA’s Wallops Flight Facility on Wallops Island, Virginia.
