Hubble Trouble & Triumph
Max Mutchler (Space Telescope Science Institute) February 8, 2005 at the Maryland Science Center

Hubble was designed to be serviced in orbit by astronauts

Hubble servicing missions:

1993 1997 1999 2002 2007? 2010?

Wide Field Camera 3 (WF3) and the Cosmic Origins Spectrograph (COS): already built and ready to go, along with new batteries and gyroscopes

Can a robot service Hubble?

De-orbit module and......"Dextre"

The Hubble Origins Probe (HOP) is a proposed 2.4 meter free flying space telescope. The HOP concept is to replicate the design of the Hubble Space Telescope with a much lighter unaberrated mirror and optical telescope assembly HOP will fly the instruments originally planned for the 4th HST servicing mission as well as a new very wide field imager, enhancing the original science mission of Hubble.

February 8, 2005

After detailed examination of the astronomical evidence that was presented to it, the committee concluded that NASA should commit to a Hubble serving mission that accomplishes the objectives of the originally planned SM-4 mission. A shuttle servicing mission is the best option for extending the life of Hubble and preparing the observatory for eventual robotic de-orbit; such a mission is highly likely to succeed. The committee concluded that the difference between the risk faced by the crew of a single shuttle mission to the ISS, already accepted by NASA and the nation, and the risk faced by the crew of a shuttle mission to HST is very small. Given the intrinsic value of a serviced Hubble, and the high likelihood of success for a shuttle servicing mission, the committee judges that such a mission is worth the risk. Over its lifetime, the HST has been an enormous scientific success, having earned extraordinary scientific and public recognition for its contributions to all areas of astronomy. Hubble is the most powerful space astronomical facility ever built.

Senator Mikulski Vows to Fight for Hubble
"Hubble's best days are ahead of it, not behind it. That's why I am so disappointed that President Bush has failed to include funding in this year's budget for a servicing mission that would extend the life of the Hubble. I led the charge last year to add $300 million to NASA's budget for a Hubble servicing mission, and I plan to do it again. I will fight in the United States Senate this year to fund a servicing mission to Hubble by 2008, a mission that would potentially increase Hubble's power and efficiency by a factor of 10 and allow us to look back almost to the beginning of the universe."
