In a mission marking the end of an era, NASA astronaut and former virus hunter Kate Rubins, using NASA’s last currently contracted seat on a Russian Soyuz spacecraft, blasts off Wednesday with two cosmonaut crewmates on a flight to the International Space Station.

This media briefing comes as NASA is potentially within a week of making its final decision on how to bring the Starliner CFT crew home. The agency is debating on if Starliner is determined to be safe or if NASA astronauts Barry “Butch” Wilmroe and Sunita “Sunni” Williams will return on a SpaceX Crew Dragon spacecraft.

As soon as next year, NASA plans to launch a CubeSat the size of a microwave oven into a unique elliptical orbit around the moon as a scout for the future lunar Gateway, a mini-space station NASA intends to use as a staging point for crewed lunar landings beginning as soon as 2024.
