Astronaut Mike Hopkins

On Dec. 24, 2013, NASA astronaut Mike Hopkins, Expedition 38 Flight Engineer, participated in the second of two spacewalks.

These spacewalks were spread over a four-day period, which were designed to allow the crew to change out a faulty water pump on the exterior of the Earth-orbiting International Space Station. He was joined on both spacewalks by NASA astronaut Rick Mastracchio, whose image shows up in Hopkins' helmet visor.
