Astronaut Christina Koch returns to earth after staying 328 days in space

NASA astronauts Christina Koch, who has spent nearly 11 months in space on the longest spaceflight by a woman landed back on Earth on February 6.

Koch conducted the first female spacewalk with fellow astronaut Jessica Meir. Koch landed back with two of her International Space Station (ISS) crewmates, Expedition 61 commander Luca Parmitano of the European Space Agency (ESA) and cosmonaut Alexander Skvortsov of the Russian space agency Roscosmos.

NASA astronaut said for her first spacewalk: “We caught each other’s eye. We knew that we were really honored with this opportunity to inspire so many, and just hearing our voices talk to Mission Control, knowing two female voices had never been on the loops, solving those problems together outside. It was a really special feeling.”

Koch completed six spacewalks in which two are with Meir. She spent 42 hours and 15 minutes outside of the station. She spent most of her time in research and experiments.

The space station acts as an orbiting laboratory. It can be used to test how different aspects of human life on Earth react to the lack of gravity.

Koch achieved various things during her stay of 328 days in space. During her stay for 328 days, she studied how long-term spaceflight affects the human body.

If an astronauts stayed for a long time in space it causes the loss of muscles and bones because of the lack of gravity. Various previous and current studies have focused on how to mitigate this and how can we prevent this from happening.

Koch was part of the vertebral investigation in which they studied preventative medicine and exercise to prevent these things.

Kidney cell investigation is another study they did on spaceflight. Kidney stones and osteoporosis happened because of bad health of the kidney.

Koch also worked on the Microgravity Crystals investigation. Christina also studied plant biology in space. She studied how the plan grows in space.

Koch excelled astronaut Peggy Whitson’s previous record of 288 days. NASA astronaut Scott Kelly still holds the all-time record with 340 days in space.
