The STS-125 mission's first spacewalk concluded Thursday at 4:12 p.m. EDT, the National Aeronautics and Space Administration said.
During the seven-hour, 20-minute excursion, astronauts John Grunsfeld and Drew Feustel removed the Hubble Space Telescope’s Wide Field Planetary Camera 2, or WFPC 2, and installed the Wide Field Camera 3, or WFC 3.
They also swapped out the Science Instrument Command and Data Handling Unit, installed a soft capture mechanism, lubricated three of the shroud doors, and one of the three latch-over center kits. They had some difficulty with the other two, installing a latch repair on one of the bolts, and partially installed a second lock. That door is now secure for when it's revisited on the mission's third spacewalk.
