NASA's Expanding Field of Vision 

Tags: Sessions, Science

NASA is hoping to get a better look at the history of universe as they expand the capabilities of the Hubble telescope. Michael Weiss, deputy program manager of the Hubble Space Telescope Program at NASA’s Goddard Space Flight Center, talked about how the new equipment will provide images from the ultraviolet, infrared, and near-infrared spectrums. The upcoming shuttle mission, which will be the fourth to service the telescope since it’s launch, will add a new wide field camera, replace gyros, repair equipment that has failed, and more.

Weiss talked about the challenges in repairing equipment sealed behind more than 100 small screws no one had anticipated removing. Plus the added difficulty of doing so in a zero gravity environment where a lost screw could irreparably damage incredibly expensive equipment while wearing the less-than-sleek space suits required for any extra vehicular activity (EVA). But in the final analysis, the effort is expected to be well worth it. Referencing a credit card, he joke, “EVA overhead: 3 1/2 hours. Changing a card: 5 minutes. Science recovery: Priceless.”
 
I found the transfer of technology impressive. Did you know you likely have a piece of technology at home or in your pocket (particularly if you’re reading this while attending the 2009 conference) that can be traced back to the original Hubble mission? Makes my digital camera a bit more interesting.
 
Other Hubble technology has been applied in other fields, including medicine. A device initially designed to eliminate damage to tools and parts during service missions is now used by brain surgeons to control torque. Apparently, you CAN have your head screwed on too tight!
 
The presentation included videos of NASA scientists explaining the challenges they faced in figuring out how to repair the equipment. You can view them online at www.nasa.gov/hubble.
