Final spacewalk completed
by colleen on May.18, 2009, under SM4
In seven hours, 2 minutes, astronauts John Grunsfeld and Drew Feustel completed all tasks for the fifth and final spacewalk of SM4. They installed batteries, removed and replaced a Fine Guidance Sensor (FGS) that helps point the telescope and they added three NOBL (New Outer Blanket Layers) for thermal protection.
Upon heading for Atlantis’ airlock, Grunsfeld wished Hubble a “good voyage.”
