Live coverage: SpaceX supply ship returns to Earth

SpaceX plans to build its massive BFR rocket boosters and spaceships inside a cavernous new factory at the Port of Los Angeles, officials announced this week.

A Russian Soyuz-2.1a rocket rolled out to a launch pad Monday at the Baikonur Cosmodrome in Kazakhstan, ready for the first crewed flight to use the modernized Soyuz booster configuration. Liftoff with two Russian cosmonauts and a veteran NASA astronaut is scheduled Thursday on an expedition to the International Space Station.

Keith Gendreau, an astrophysicist at NASA’s Goddard Space Flight Center, recently spoke with Spaceflight Now about a new experiment on the International Space Station to demonstrate X-ray communications in space for the first time.
