NASA will livestream a news conference following astronaut Christina Koch's return to Earth. The 41 years old American astronaut landed in Kazakhstan aboard the Russian Soyuz MS-13 spacecraft on February 6 after spending 328 days aboard the International Space Station. She was a Flight Engineer for Expeditions 59, 60 and 61 and set the record for the longest single continuous stay in space for a woman. Koch also performed the first all-female spacewalk with Jessica Meir on October 18 2019, as part of a lengthy series of upgrades to the ISS’ power systems and physics observatories.
