In an attempt to end rumours, Indian-origin NASA astronaut Sunita Williams, who has been in space since June, said that she weighs the same as she did when she arrived at the International Space Station (ISS).

The "rumours" started floating following her recent images where she looked weaker and thinner after spending at least 150 days in space.

The images triggered concerns about the rapid weight loss of Williams.

"...I think my body has changed a little bit but I weigh the same...," Williams, who is the Space Station Commander, told the media in a video interview that was shared by NASA.

"There are a lot of changes that go on here... It's funny, I think there's some rumours around that I am losing weight and stuff... No, I am actually right at the same amount... we go weigh ourselves, we have a spring mass... Butch and I weigh ourselves the same way that I was when I got up here," she said.

Williams and her fellow astronaut Barry (Butch) Willmore have been at the ISS for nearly five months now.

They launched aboard Boeing's Starliner spacecraft on June 5 for its first crewed flight and arrived at the space station on June 6. 

However, facing delays, space debris threats, helium leaks and technical glitches, the Starliner spacecraft on which they travelled is stuck there.
