Astronauts Michael Massimino and Michael Good are out in space this morning giving the Hubble Space Telescope new gyroscopes and batteries in the second of five scheduled spacewalks.  The gyroscopes are an integral element of the pointing system of the Hubble and approximately half were not working.  The new batteries replace Hubble’s original 20 year old batteries.

Yesterday, astronauts had trouble removing the bolt that held the the old Wide Field and Planetary Camera 2 to the inside of Hubble.  But after applying a little good old fashioned elbow grease, the astronauts were able to remove the bolt & the old camera.  For an interesting story regarding their bolt trouble, see here.
