STS-125 EVA#4 Summary of the fourth spacewalk

STS-125 Crew Completes Fourth Spacewalk

STS-125 mission specialists Mike Massimino and Mike Good completed the missions fourth spacewalk today at 5:47 p.m. EDT. The spacewalkers continued repairs and improvements to the Space Telescope Imaging Spectrograph (STIS) that will extend the Hubbles life into the next decade. The spacewalk lasted 8 hours, 2 minutes.

Massimino and Good replaced a low-voltage power supply board, which contains a failed power converter. Due to this power supply failure, STIS has been in safe mode since August 2004.

A delay caused by a bolt removal issue forced the spacewalkers to cancel the installation of a new protective thermal insulation panel on Hubble. Ground controllers are working various options for the fifth and final STS-125 spacewalk on Monday scheduled for 9:16 a.m.
