Indian-origin astronaut Sunita Williams, 59, will now return to Earth from the International Space Station (ISS) after late March or April 2025. NASA confirmed the delay, ensuring the safety and well-being of all crew members aboard the ISS.

Reason Behind the Delay

NASA announced that the SpaceX Crew Dragon spacecraft, initially scheduled to launch earlier, will now take off no sooner than late March. This adjustment follows earlier delays caused by safety issues with the Boeing Starliner spacecraft that carried Ms. Williams to the ISS in June. Originally planned as a 7-to-10-day mission, her stay has been extended by nearly a year.

Effects of Extended Space Stay

Prolonged stays in microgravity affect the human body, including loss of bone density, muscle mass, and changes in organs like the heart and eyes. Astronauts undergo rigorous post-return rehabilitation to readjust to Earth’s gravity. However, NASA emphasized that Ms. Williams is in good health, engaging in weight training and maintaining her fitness aboard the ISS.

Williams’ Stellar Space Career

This mission marks Ms. Williams’ third spaceflight. Over her illustrious career, she has spent more than 517 days in space and previously held the record for the most time spent on spacewalks, logging over 51 hours of extra-vehicular activity (EVA).

NASA’s Crew Transition Plan

NASA's decision to delay the Crew-10 mission aligns with operational priorities. Crew-9, which includes Sunita Williams, will hand over duties to the Crew-10 team upon their arrival, ensuring a seamless transition for ongoing experiments and maintenance aboard the ISS.

Space Station Well-Prepared

NASA confirmed that the ISS received two resupply missions in November, delivering essential items like food, water, clothing, and holiday supplies. Rumors about Ms. Williams’ health were dismissed, with assurances of her active participation in training and maintaining her fitness.

Anticipation for 2025

As the ISS continues to serve as a hub for groundbreaking research, Ms. Williams’ delayed return highlights the operational complexities and meticulous planning required for space missions. Her eventual return will mark another milestone in her extraordinary career.
