Cygnus Cargo Craft Fires Engine for Limited Reboost Station – Space Station

Northrop Grumman’s Cygnus space freighter, with its prominent cymbal-shaped solar panels, is shown attached to the space station.

On Saturday, June 25, Northrop Grumman’s Cygnus completed its first limited reboost of the International Space Station. Cygnus’ gimballed delta-speed motor was used to adjust the space station’s orbit through an increase in the space station’s altitude. The maneuver took 5 minutes, 1 second and raised the station’s altitude by 1/10 of a mile at apogee and 5/10 of a mile at perigee. This Cygnus mission is the first to offer this enhanced capability as a standard service for NASA, following a test of the maneuver that was conducted in 2018 during Cygnus’ ninth resupply mission. Cygnus arrived at the orbital outpost in February and is expected to depart the space station on Tuesday, June 28, where it will burn up harmlessly in Earth’s atmosphere. NASA TV coverage for the launch will begin at 5:45 a.m. EDT on NASA televisionthe agency’s website and Nasa app.
