The space shuttle Atlantis launched today for STS-125, a mission to repair and upgrade the enormously successful Hubble Space Telescope for another five years of service.[youtube]'s a challenging mission involving five spacewalks and repairs on instruments that NASA says "were never designed to be repaired in space" and were actually "specifically designed not to come apart." Best of luck to everyone involved, especially the brave astronauts.There's a longer video with more angles and commentary here.
