Hubble to be even Hubbleyer

"The terrific thing about NASA chief Michael Griffin’s decision to launch a Hubble servicing mission—the telescope’s fifth since 1990—isn’t simply that the spacecraft will be able to limp along for another four years.

After astronauts visit Hubble on this latest mission (set to launch no earlier than May 2008), the telescope will be more powerful than it has ever been, thanks to some incredible new instruments being tested now.

If all goes well, the servicing mission should keep the new, improved Hubble working until 2013, when its successor, the James Webb Space Telescope, is set to launch."

You get all this (and more) for the price of 2 days military ops in Iraq.
