STS-125 astronauts Mike Massimino and Mike Good are just leaving the airlock to start the fourth EVA of the ongoing Hubble servicing mission. The Atlantis astronauts are doing amazing work on this mission. EVA's one and two were pretty tough - they accomplished their tasks, but they ran into problems that caused the EVA's to run long. Yesterday's third EVA was expected to be even tougher, with the unprecedented on-orbit circuit board replacement repair of the ACS camera considered a long shot for success. But astronauts Grunsfeld and Feustel accomplished all phases of this repair in about three hours of the six and a half hour space walk.
The picture here is from EVA #1 and shows Andrew Feustel reflected in the John Grunsfeld's helmet visor. There are tons of great high resolution digital photos at NASA's Space Shuttle Gallery including STS-125 photos as recent as yesterday (EVA #3).
