Stranded astronauts Barry 'Butch' Wilmore and Sunita 'Suni' Williams are nearing their return date, and have now revealed the hardest factor of their nine-month stay aboard the International Space Station (ISS).

NASA astronauts Suni Williams and Butch Wilmore have said they were unaware of any offer by Elon Musk to bring them back to Earth early, in a press conference from the International Space Station (ISS) on Tuesday.

On a crisp January evening, as the International Space Station (ISS) streaked across the sky at 17,500 miles per hour, Charline Giroud, an amateur astrophotographer and biochemist at the University of Oxford, pointed her telescope toward the heavens. Her goal was ambitious: to capture an image of an astronaut during a spacewalk.
