Video: Soyuz MS-01 leaves the space station for landing

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.

NASA and SpaceX officials are moving forward with preparations to launch the next commercial Crew Dragon mission to the International Space Station next week after a Flight Readiness Review Thursday, pending a final evaluation of a discovery by SpaceX that it has potentially been loading slightly more propellant than expected into its Falcon 9 rockets.

Ax-4 will mark the first time an astronaut from India or Poland visits the International Space Station. The mission will be commanded by former NASA astronaut Peggy Whitson, making her second trip to the ISS on behalf of Axiom Space.
