We have officially cleared the Orbiter for re-entry as the the thermal protection system appeared to be in great shape.
Astronauts John Grunsfeld and Drew Feustel are already 2 hours into a planned six-and-a-half-hour spacewalk today to install a new wide-field camera and a replacement data processing computer. The spacewalkers also plan to install new handles on Hubble equipment bay doors to improve access and a grapple fixture that will permit future astronauts, or a robotic spacecraft, to latch onto the telescope so it can be driven out of orbit at the end of its life.
