Well, if you're gonna put a portrait of your mug on Instagram for the whole world to see, this is the way to do it. Taken from outside the ISS during one of the two spacewalks required to replace a faulty water pump, this selfie-like portrait (it is NOT a selfie, contrary to just about every headline you'll read) was uploaded to NASA's Instagram account yesterday.
NASA astronaut Rick Mastracchio just arrived on the ISS last week (with the Olympic torch in tow, no less), and even though he wasn't one of the astronauts who got to take the Olympic torch for a spacewalk/photo shoot, he wasted no time starting to upload photos from orbit.
All of the photos he's uploaded (gallery below) are awesome for one reason or another, but one in particular has gotten a bunch of attention. Uploaded yesterday, the photo above shows the view Mastracchio and his fellow astronauts have while exercising on the ISS.
