STS-125 MS5 Feustel and MS3 Grunsfeld during EVA1

S125-E-007221 (14 May 2009) --- What appears to be a number of astronauts, because of the shiny mirror-like surface of the temporarily-captured Hubble Space Telescope, is actually only two -- astronauts John Grunsfeld (left) and Andrew Feustel. The mission specialists are performing the first of five STS-125 spacewalks and the first of three for this duo.
