#Now in 2009, astronauts John Grunsfeld & Drew Feustel (SciAstro & Astro_Feustel) replace some of Hubble's original batteries with new ones, which help the spacecraft store energy collected by its solar panels. #SM4live https://www.flickr.com/photos/nasahubble/28162761821/in/album-72157670398668456/
#Now in 2009, astronauts John Grunsfeld (SciAstro) & Drew Feustel (Astro_Feustel) install the Cosmic Origins Spectrograph, the most sensitive spectrograph ever flown on Hubble. #SM4live https://www.flickr.com/photos/nasahubble/33963974698/in/album-72157670398668456/
#Now in 2009, astronauts John Grunsfeld & Drew Feustel remove COSTAR (Corrective Optics Space Telescope Axial Replacement), which corrected Hubble's vision since 1993. It's no longer needed because all of Hubble's instruments now have a correction built …
#Now in 2009, astronaut Mike Good replaces one of Hubble's original battery units with a new one. These batteries allow the solar-powered observatory to store energy for use when Hubble is in Earth's shadow. #SM4live https://www.flickr.com/photos/nasahubble/27562324923/in/album-72157670398668456/
#Now in 2009, astronauts Mike Massimino (Astro_Mike) and Mike Good begin the 2nd spacewalk of Hubble's last servicing mission. Their goal is to install new gyroscopes and batteries on the spacecraft. #SM4live https://www.flickr.com/photos/nasahubble/28143691036/in/album-72157670398668456/
