NASA astronaut and cosmonauts return after 245 days in space

What happened: NASA astronaut Jonny Kim and cosmonauts Sergey Ryzhikov and Alexey Zubritsky have safely returned to Earth after spending 245 days aboard the International Space Station.

Why it matters:

  • Their long-duration mission contributes valuable data on human health and performance in space.
  • The return marks a successful international collaboration between NASA and Russian space agencies.

MNN Take: Extended stays on the ISS help scientists understand the effects of microgravity on the human body, which is crucial for planning future deep space missions.
