Both Suni Williams and Butch Wilmore are in good health on the ISS, NASA confirms, despite tabloid rumors suggesting otherwise.

Suni Williams and Butch Wilmore, the two NASA astronauts who have been stuck at the International Space Station for more than 150 days and counting, are speaking out amid health concerns, reassuring the public they are doing well and explaining how they keep themselves healthy.

A recent photo of Williams aboard the ISS sparked rumors about her health, restoring the media's habit of prying into the appearance of women astronauts.

NASA astronaut Suni Williams says her weight is stable aboard the International Space Station, rebutting tabloid claims that her orbital stay has made her emaciated.
