The Cygnus spacecraft successfully departed the International Space Station three months after arriving at the space station to deliver about 7,500 of scientific experiments and supplies to the orbiting laboratory.
Within 24 hours of its release, Cygnus will begin its secondary mission, hosting the Spacecraft Fire Safety Experiment – IV (Saffire-IV), which provides an environment to safely study fire in microgravity. It also will deploy a series of payloads. Northrop Grumman flight controllers in Dulles, Virginia, will initiate Cygnus’ deorbit to burn up in Earth’s atmosphere Friday, May 29.
