Watch the Falcon 9 and Crew Dragon arrive at the launch pad (members only)

A NASA-funded satellite that launched last year on the third flight of SpaceX’s Falcon Heavy rocket has begun a sequence of thruster firings to begin falling out of orbit after successfully demonstrating the effectiveness of a non-toxic fuel that could fly on future space missions.

Closing out a three-day chase from a launch pad in Virginia, Orbital ATK’s Cygnus cargo freighter arrived Thursday at the International Space Station with nearly 7,400 pounds of equipment, delivering food, a quantum physics experiment, and CubeSats for later deployment in orbit.

An unpiloted space plane developed by Sierra Nevada Corp. will join cargo carriers built by SpaceX and Orbital ATK to resupply the International Space Station beginning in 2019, NASA announced Thursday.
