More Incredible Images from the Space Station 'Emergency' EVA

The image above could go down as an iconic shot of space exploration. Taken during the 'emergency' spacewalk last Saturday to fix the leaking ammonia coolant in the pump and flow control system for the International Space Station's power-supplying solar arrays, visible is astronaut Tom Marshburn taking a look at planet Earth. He shared the picture today on

Twitter

, saying, "Leaving is bittersweet. It's been an unbelievable ride. Can't wait to see what's next!"

Marshburn is scheduled to return back to Earth later today along with ISS commander Chris Hadfield and cosmonaut Roman Romanenko.
