NASA’s Astronaut Christina Koch comes back to Earth after record stay in space

After spending 328 days on the International Space Station (ISS), NASA astronaut Christina Koch returned back to Earth yesterday after completing the longest ever single spaceflight by a woman.

Koch arrived in space in March 2019 alongside European astronaut Luca Parmitano and Russian cosmonaut Alexander Skvortsov. During the 11 month mission, Koch performed various experiments including studying the effects of microgravity on Mizuna mustard greens, combustion, bioprinting, and kidney diseases. In addition, Koch herself was a research subject to determine the long-term effects of spaceflight on the human body.
