For the second time in a month, NASA has delayed the planned launch of a Hubble Space Telescope servicing mission to give engineers more time to ready a replacement for a balky pointing device on the observatory. |

For the second time in a month, NASA has delayed the planned launch of a Hubble Space Telescope servicing mission to give engineers more time to ready a replacement for a balky pointing device on the observatory.
Shuttle Columbia and crew of seven astronauts–including former Georgia Tech professor Michael Massimino–now are slated to blast off Feb. 28 on a mission to outfit the flagship telescope with new solar arrays, a critical power switching unit and an advanced planetary camera.
Once targeted for launch on Feb. 14, the flight initially was pushed back to Feb. 21 so that engineers could ready a spare for one of four actuators that play a key role in precisely pointing the telescope at celestial targets.
Mission specialists Massimino and Jim Newman will carry out the repair work, and two other astronauts, John Grunsfeld and Richard Linnehan, also will conduct servicing jobs on the telescope during the 11-day flight. |
