After six months working on the International Space Station, NASA astronaut Kate Rubins is returning to Earth tonight alongside her mission colleagues Sergey Ryzhikov and Sergey Kud-Sverchkov. NASA will have live coverage through the night of the crew’s departure from ISS and return to Kazakhstan.

NASA is buying SpaceX’s Starship rocket a $2.9 billion ticket to the Moon, and the ramifications of that decision are plentiful. The Washington Post was first to report that Starship is NASA’s sole choice for the Artemis human landing system for astronauts going to the Moon. The agency later held a press conference with reporters during which it made the news official while adding more color to the story. NASA has also published a source selection statement written by Kathy Lueders detailing specifics around its decision.

NASA will soon have a new second-in-command leading America’s space agency. The Biden administration announced its intent to nominate former astronaut Pam Melroy for the role of deputy administrator.

NASA is actively working on Artemis, a space exploration program that includes a mission to send the first woman and first person of color to the Moon during this decade. Astronauts will travel from Earth in NASA’s Orion spacecraft which will launch on the space agency’s Space Launch System rocket. SLS gives Orion the boost it needs to reach the Moon, but Orion doesn’t touch down on the lunar surface. A third vehicle called a human landing system is needed to transport astronauts to the surface of the Moon. One year ago, NASA selected three potential partners for providing the human landing system for Artemis 3, the first mission in the program that includes walking on the Moon.

Later today, the U.S. space agency will officially announce which partner it will proceed in funding for development. Ace Washington Post space reporter and author Christian Davenport has scooped the 4 p.m. EDT press conference with source selection details. According to Davenport, SpaceX has won the contract with its Starship-based human landing system bid.

Apple is launching its first podcast series connected to an original series on its Apple TV+ video streaming service.

Launch service startup Astra successfully reached space with its Rocket 3.2 vehicle for the first time in December. Now the satellite launch company is setting its sights on a new target: the New York Stock Exchange. Astra plans to join the small but growing list of publicly traded space companies this year.

SpaceX will conduct its third mission to send astronauts to space on April 20 from Launch Complex 39A at Kennedy Space Center in Florida. A Falcon 9 rocket and Crew Dragon spacecraft will send two NASA astronauts, one JAXA astronaut, and one ESA astronaut to the International Space Station. The mission called Crew-2 will be the first SpaceX flight for a European Space Agency astronaut and the second for a Japan Aerospace Exploration Agency astronaut.
