During Wednesday's fast-track spacewalk, NASA astronaut Rick Mastracchio complained that his arms were too short to take a selfie. But that didn't stop him from trying, or from sharing the results.
"The spacesuit makes it very difficult to get a good selfie. I tried several today," Mastracchio tweeted hours after he and a crewmate, Steve Swanson, replaced a bad backup computer box on the International Space Station.
Taking a space selfie was a toughie indeed, not only because Mastracchio was wearing a bulky spacesuit but also because he was in the space station's shadow, silhouetted against that bright blue planet in the background. But all things considered, Mastracchio's selfie is probably worth keeping in the photo album, along with his other shots.
