Last voyage for Hubble's keeper

On May 12, John Grunsfeld and six other astronauts commanded by Scott Altman are scheduled to ride to the Hubble Space Telescope's rescue one last time aboard the shuttle Atlantis. This will be the fifth and last time astronauts visit Hubble. When the telescope's batteries and gyros finally run out of juice sometime in the middle of the next decade, NASA plans to send a rocket and drop it into the ocean.

If all goes well, Hubble will be left at the apex of its scientific capability. As chief Hubble repairman for the past 18 years, Grunsfeld has been intertwined with the Hubble telescope physically, as well as intellectually and emotionally.

Full story from the New York Times.
