Fourth spacewalk today
by colleen on May.17, 2009, under SM4
Astronauts Mike Massimino and Mike Good will conduct SM4’s fourth spacewalk today, focusing on the repair of the STIS instrument (Space Telescope Imaging Spectrograph). A power supply failure in 2004 rendered the “black hole hunter” inoperable. Watch NASA’s video about the STIS repair.
