This afternoon (Aug. 6), over three months after it arrived in orbit, the Northrop Grumman Cygnus cargo spacecraft successfully undocked from the International Space Station and proceeded to drift off into the vacuum of space to begin the second part of its mission.
NASA astronauts Nick Hague and Christina Koch used the space station's Canadarm2 robotic arm to undock the spacecraft and send it on its way. The Cygnus separated from Canadarm2 at 12:15 p.m. EDT (1615 GMT).

Launched on April 17, 2019, the Cygnus CRS-11 cargo vessel docked with the space station on April 19. When it arrived, NASA astronaut Anne McClain and Canadian Space Agency astronaut David Saint-Jacques used the Canadarm2 to grapple the craft. The Cygnus, known as the S.S. Roger Chaffee, ferried 7,600 lbs (3,442 kg) of supplies, including science experiments and necessities for the crew, to the station.

Among the science equipment and scientific experiments sent to the station, two Astrobee robots were launched aboard Cygnus (and were joined by a third earlier this summer). Now, one of those little robots has started to fly and begin learning how to assist astronauts on board.
