An EVA selfie. The space suit makes it very difficult to get a good selfie. I tried several today. http://t.co/GvMEOj3ewu— Rick Mastracchio (@AstroRM) April 23, 2014 NASA astronaut Rich Mastracchio aboard the International Space Station took a seriously impressive selfie Wednesday during an EVA—short for Extra-Vehicular Activity. That’s astronaut-ese for spacewalk. As one might imagine, the confines of a spacesuit make it difficult to snap a proper selfie, but he was able to pull it off after a few tries. Mastracchio may win for coolest selfie ever with this one.
