Second of five Hubble spacewalks under way

CAPE CANAVERAL, Fla., May 15 (UPI) -- Two U.S. astronauts worked Friday to install six gyroscopes and a new set of batteries in the Hubble Space Telescope, NASA officials said.

Mike Massimino and Mike Good took the second of five spacewalks aimed at repairing and upgrading the telescope for the last time, Florida Today reported.

Their work, scheduled to last 6 1/2 hours, was assisted from inside the shuttle Atlantis by astronauts John Grunsfeld and Drew Feustel, who completed the mission's first spacewalk Thursday, NASA said.
