Astronaut Mike Hopkins, Expedition 38 Flight Engineer, is shown in this handout photo provided by NASA as he participates in the second of two spacewalks which took place on December 24, 2013, released on December 27, 2013.

He was joined on both spacewalks by NASA astronaut Rick Mastracchio, whose image shows up in Hopkins' helmet visor.
