Indian-origin astronaut Sunita Williams has broken the record for total spacewalking time by a woman by logging 62 hours and 6 minutes of spacewalk.

Williams and her colleague Butch Wilmore, who have been stranded on the International Space Station (ISS) since June 2024, conducted a spacewalk on Thursday.

The duo ventured outside the ISS to remove degraded radio communications hardware and collect samples that may show whether microorganisms exist on the exterior of the orbiting laboratory.   

The spacewalk began at 7:43 am Eastern Time (ET) and concluded at 1:09 pm ET, lasting 5 hours and 26 minutes.  

It was the ninth spacewalk for Williams and the fifth for Wilmore.

“NASA astronaut Suni WIlliams just surpassed former astronaut Peggy Whitson’s total spacewalking time of 60 hours and 21 minutes,” NASA said in a post on X.

She surpassed Whitson’s record for total spacewalking time by a female astronaut. Williams now has 62 hours and 6 minutes of total spacewalk time, fourth on NASA’s all-time list, according to NASA.

In 2012, during a trip to the ISS, Williams became the first person to finish a triathlon in space, during which she simulated swimming using a weight-lifting machine and ran on a treadmill while strapped in by a harness so she wouldn’t float away.

Williams, 59, and Wilmore went on what was meant to be an eight-day mission to the ISS aboard Boeing’s Starliner in June 2024.

However, technical issues including helium leaks and thruster malfunctions meant that the Starliner was unsafe for their return.

NASA plans to bring them back to Earth in late March aboard a spaceship built by SpaceX, a rival company of Boeing.Despite these setbacks, the astronauts have continued their work aboard the ISS while awaiting a safe journey home.
