Although they still need to re-deploy Hubble to orbit on Tuesday, the STS-125 astronauts performed the fifth and final EVA today, and completed all the planned upgrades for the telescope. I was busy today moving my daughter home from school, so I didn't get to follow any of the final EVA, but the summary I read on SPACE.COM indicates that it went extremely well. As an optical engineer as well as a space and astronomy enthusiast, I'm especially happy to know that the world's best-known and most-loved optical system is ready to take on the universe for another five years or more.The NASA photo above shows John Grunsfeld on today's final EVA.
