After spending months in space Sunita Williams and Butch Wilmore are set to return to Earth But how will gravity impact their bodies Here’s what happens after re-entry

Nasa astronauts Sunita Williams and Butch Wilmore, after spending more than eight months in space, are expected to return to Earth on March 19. After returning, however, the two astronauts might find it difficult to readapt life on land due to Earth’s gravity.

Sunita Williams and Butch Wilmore flew to the International Space Station's Boeing Starliner on June 5 last year and have been stuck since due to technical problems with the spacecraft.
