US Cargo Ship Set to Depart Space Station, Live NASA TV Coverage

One month after launching from NASA's Wallops Flight Facility in
Virginia, Orbital ATK's Cygnus cargo spacecraft is set to leave the International Space Station at 8:20 a.m. EST Monday, Nov. 21. Live coverage
of the spacecraft departure will begin at 8 a.m. on NASA Television and
the agency's website.

Cygnus arrived at the space station Oct. 16 with more than 5,100 pounds
of cargo to support science experiments from around the world. The spacecraft will be detached from the Earth-facing side of the station's Unity module using the Canadarm2 robotic arm, operated by ground controllers. Robotics controllers will maneuver Cygnus into place, and then Expedition 50 robotic arm operators Shane Kimbrough of NASA and Thomas Pesquet of ESA (European Space Agency) will give the command for its release.

Experiments delivered on Cygnus supported NASA and other research investigations
during Expeditions 49 and 50, including studies in biology, biotechnology, physical science and Earth science - research that impacts life on
Earth. Investigations included studies on fire in space, the effect of lighting on sleep and daily rhythms, collection of health-related data,
and a new way to measure neutrons.

Five hours after departing the station, the Saffire-II experiment will intentionally ignite a fire inside a module aboard the uncrewed spacecraft. The second in a series of three, the experiment allows researchers to
study a realistic fire on an exploration spacecraft. Instruments on the
Cygnus will measure flame growth, oxygen use and more. Results could determine microgravity flammability limits for several spacecraft materials, validate NASA\u2019s material selection criteria, and help scientists understand
how microgravity and limited oxygen affect flame size. The investigation
is important for the safety of current and future space missions.

Cygnus also will release four LEMUR CubeSats from an external deployer
on Friday, Nov. 25, sending them to join a remote sensing satellite constellation
that provides global ship tracking and weather monitoring.

The spacecraft will remain in orbit until Sunday, Nov. 27, when its engines will fire twice, pushing it into Earth's atmosphere, where it will burn
up over the Pacific Ocean.
