STS-125: Flight Day 5
One down, four more spacewalks to go! Astronauts Michael Massimino and Michael Good are now 5 hours into the second spacewalk to swap out the Hubble Space Telescope's six stabilizing gyroscopes and three of its aging nickel-hydrogen batteries. They're running a little behind schedule, but Mission Control has determined that the astronauts have a few more hours of spacesuit consumables, giving ample time to get the planned battery replacement task completed today!
