On Wednesday, June 14, 2016, the Cygnus OA-6 cargo ship departed the ISS after completing 80 days berthed at the station.
The cargo ship was released by the station’s robotic arm and unberthed from the nadir port of Unity Node1.
After it separated to a safe distance from the station, the SAFFIRE experiment was conducted to better understand how flames will behave in weightlessness and improve fire safety techniques for future spacecraft.
On June 22, the cargo ship will be deorbited for a harmless disposal over the South Pacific.
The next Cygnus cargo mission to the station will launch atop the redesigned Antares rocket.
