NASA's most-flown shuttle, Discovery, landed for the final time today at the Kennedy Space Center in Florida. Over the course of 39 missions spanning the course of 26 years, Discovery traveled 148,221,665 miles. Career highlights: Launched the Hubble telescope, delivered new modules to the International Space Station. NASA's other two remaining space shuttles—Endeavour and Atlantis—are scheduled for the glue factory later this year. [ABCNews, Image of Discovery above the northwest coast of Morocco via AP]

Two weeks ago, NASA spokespeople acknowledged that the $6 billion Hubble Space Telescope had stopped transmitting data back to Earth.

Five of the six "redundant components" activated this week haven't been powered up since 1990. Before you type this is not news, read Nasa's carefully crafted PR prose from 1999. Look how much we've gotten used to commodity PC hardware since then:
