NASA astronauts Sunita Williams and Barry Wilmore arrived at the International Space Station on June 5 on Boeing's Starliner spaceship. They both were scheduled to return to Earth in the same spacecraft in 8-10 days.

The extended stay means she will be celebrating her birthday in space. The 1965-born former US Navy pilot turns 59 on September 19.

NASA astronauts took off in the Boeing Starliner spacecraft on June 5 with an aim to test the Starliner's capabilities for commercial space travel. NASA administrator Bill Nelson said the spaceflight in Starliner is risky.

Sunita Williams mother Bonnie Pandya said that the delay in her daughter's return doesn't bother her much, as she knows that her daughter is safe.

Indian-origin NASA astronaut Sunita Williams, while interacting with school students in India in 2018, said that she became a pilot inspired by Tom Cruise's Top Gun movie.

Sunita Williams' husband Michael Williams is a pilot and is currently a police officer in Texas. She has done Bachelor of Science in Physical Science in 1987. Studied Master of Science in Engineering Management in 1995.

Speaking about how being in space affects human body, Williams revealed that though there are several mitigation methods that NASA has in place, there are some things like radiation that astronauts cannot completely avoid.
