8. Tom Marshburn
This amazing image of NASA flight engineer Tom Marshburn was captured on May 11, 2013, during a five-and-a-half-hour spell of extravehicular activity (EVA). Marshburn posted the picture on his Twitter feed two days later as he was returning home from Expedition 35 to the International Space Station. The tweet stated, “Leaving is bittersweet. It’s been an unbelievable ride.” And the way the astronaut seems to be staring down at Earth glowing beneath him in the picture, it’s easy to see why he might say such a thing. What’s more, although Marshburn hasn’t actually confirmed that he took the photo himself, it has nevertheless been described as an “unbeatable” or “ultimate” selfie by online viewers.
7. Steve Robinson
The image mirrored in NASA flight engineer Steve Robinson’s helmet here is Space Shuttle Discovery’s heat shield. On August 3, 2005, Robinson was in the middle of performing a never-before-accomplished repair job on the shield, located beneath the shuttle, when he took the picture. This was just one of three spacewalks completed by Robinson on Discovery’s STS-114 mission, and it was totally unexpected. Considering the work done and the photograph, it seems to have been a good day at the office for the astronaut.
6. Joseph R. Tanner
The Sun, the Earth, the stark blackness of space and the International Space Station’s multifunctional Canadarm2 can all be seen in this exquisite self-portrait by NASA mission specialist Joseph R. Tanner. The photo was taken on September 12, 2006, on the first of two mission spacewalks for Tanner, who may have taken a break from working on trusses and solar arrays to snap the picture. Tanner logged more than 13 EVA hours during the 2006 Space Shuttle Atlantis STS-115 mission alone.
