Sunita Williams Return Date: How NASA plans to her back and what happens to her body after 10-month wait in Space

NASA astronauts Sunita Williams and Butch Wilmore are finally preparing for their return to Earth after an extended stay on the International Space Station (ISS). Originally meant to last just ten days, their mission stretched to nearly ten months due to technical issues with Boeing's Starliner spacecraft. Now, they will travel back aboard SpaceX’s Crew Dragon capsule, with their journey home scheduled for mid-March.

The Crew-10 Mission and Transition Plan

Their return is part of a carefully coordinated crew transition. Crew-10, consisting of NASA astronauts Anne McClain and Nichole Ayers, JAXA astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov, is set to launch on March 13 at 5:18 am IST. This team will relieve Crew-9, allowing Williams and Wilmore to return.

Once Crew-10 arrives and completes a handover process that could take up to a week, Williams and Wilmore will board the Crew Dragon Freedom spacecraft. Their departure from the ISS is tentatively set for March 16 at 6:30 pm IST, but the timeline is subject to change based on weather conditions.

Why the Extended Stay?

Williams and Wilmore originally launched aboard Boeing’s Starliner capsule in June 2024 for its inaugural crewed flight test. The mission was supposed to last just over a week, but problems with the Starliner’s helium leaks and propulsion system led to repeated delays.

NASA eventually decided to return the Starliner to Earth without a crew. It landed safely in New Mexico in September 2024, leaving Williams and Wilmore stranded at the ISS until an alternative return plan was arranged.

What will adjusting to Life Back on Earth be like for Sunita Williams?

Spending nearly ten months in microgravity will take a toll on their bodies. Former NASA astronaut Leroy Chiao explained that astronauts experience “baby feet” upon returning, as foot calluses wear off in weightlessness. “You basically lose the thick part of your skin,” Chiao said.

Beyond that, astronauts often struggle with dizziness and nausea. Terry Virts, another former astronaut, described it as feeling “really heavy and really, really dizzy.” The body needs weeks to readjust to Earth’s gravity.

The delay in bringing Williams and Wilmore home also stirred political debate. Former U.S. President Donald Trump and SpaceX CEO Elon Musk criticised the Biden administration, arguing that NASA had not acted quickly enough to resolve the situation. However, NASA maintained that safety was the top priority.

The return journey will be closely monitored by NASA and SpaceX. The spacecraft will re-enter Earth’s atmosphere before splashing down in the Atlantic Ocean. Weather conditions and de-orbiting procedures will determine the exact timing.

As Williams and Wilmore prepare for their long-awaited return, their mission highlights both the challenges of spaceflight and the importance of flexibility in space exploration. For now, all eyes are on the upcoming Crew-10 launch, which will set the final stage for their journey home.
