Live In Orbit: Astronauts Suited Up For 3rd Walk

Two NASA astronauts are suited up in the airlock of shuttle Atlantis, preparing to head outside on the third of five spacewalks to service the Hubble Space Telescope.

Atlantis lead spacewalker John Grunsfeld and mission specialist Drew Feustel have donned protective spacesuits and are preparing to depressurize the airlock. That will set the stage for the opening of the airlock hatch and an excursion aimed at installing a new science instrument on Hubble and repairing another.

The astronauts are running a bit behind schedule. They were slated to embark on the spacewalk at 9:16 a.m. but the spacewalk probably won't start before 9:30 a.m.
