One of the strangest experiences in space is one of the simplest on Earth: sleeping. On the shuttle, you strap your sleeping bag to the wall or the ceiling or the floor, wherever you want, and you get in. It's like camping. The bag has armholes, so you stick your arms through, reaching outside the bag to zip it up. You tighten the Velcro straps around you to make you feel like you're tucked in. Then you strap your head to the pillow—a block of foam—with another Velcro strap, to allow your neck to relax. If you don't tuck your arms into the bag, they drift out in front of you. Sometimes you wake up in the morning to see an arm floating in front of your face and think, "Whoa! What is that?" until you realize it's yours.

The NASA astronaut was out on a spacewalk with crew member Steve Swanson to replace a backup computer box on the International Space Station when he decided to take a photo.

"The space suit makes it very difficult to get a good selfie. I tried several today," Mastracchio said of the photo.

NASA has hired artist Ted Southern and his company Final Frontier Designs to design lightweight, cost-effective spacesuits for civilian travelers. Previously to this, Ted’s most high-profile work was probably the elaborate, glitter-covered wings you ignore during theVictoria’s Secret fashion show. He’s also designed costumes for Cirque du Soleil and Broadway. So yes, space is about to get fabulous.
