Videos: Previewing SpaceX’s eighth International Space Station resupply launch

Concluding 80 days attached the International Space Station, the commercial Cygnus cargo ship will be detached to fly away Tuesday for an unprecedented onboard fire experiment before re-entering the atmosphere next week.

NASA has directed Boeing and SpaceX to halt activities under contracts awarded last month to build commercial space taxis to ferry astronauts to the Space Station while the U.S. Government Accountability Office reviews a protest of NASA’s decision filed by Sierra Nevada.

Boeing has reshuffled a sequence of test flights planned for the company’s CST-100 Starliner capsule after stuck valves inside a test version of the ship’s service module caused a fuel spill in June, delaying the commercial spacecraft’s first unpiloted orbital demo mission until late this year or early 2019, and moving back the first crew launch to mid-2019, a company official said Wednesday.
