Overhauling the Hubble Space Telescope requires much more than astronaut elbow grease in zero-G: More than 60 new tools had to be created in a multimillion-dollar effort that involved trips to the hardware store - and to the toy box.
The tools took their share of the spotlight during this week's briefings on NASA's final Hubble servicing mission,conducted at Goddard Space Flight Center in Maryland as well as Johnson Space Center in Houston.
'We had to develop a whole new class of tools for spacewalking,' said astronaut John Grunsfeld, who will be making his third service call on the Hubble during next month's mission.
At Goddard,we got an up-close look at the gizmos in action from the engineers who developed them for Grunsfeld and the Atlantis mission's other spacewalkers.
One of the indispensible items for Hubble's handymen will be the Mini Power Tool, a shiny pistol-shaped screwdriver/drill that has an LED light at the tip to illuminate the space telescope's innards

The bottom line is texting is at least 4 times more expensive than transmitting data from Hubble, and is likely to be substantially more than that.
- University of Leicester space scientist Nigel Bannister

If wireless providers applied the same per-byte pricing scheme they use for SMS texting to other data transmitted over their cellular networks it would cost nearly $6,000 to download a single 4 MB song. Yet, the price of text messaging has doubled industry-wide in the last three years.
Why?
A good question. And one that's finally being asked by Congress
