Satellite Refueled By Another Satellite in Space

This event is interesting. Two satellites have successfully come together so that one can refuel the other. The ASTRO satellite was designed with this in mind, but this is the first test of its capabilities. Besides a few minor glitches, it appears that we may now be able to refuel satellites in space (well orbit). This is a huge improvement, as it means that satellites will no longer have to die. They can continue to be used until something actually breaks rather than running out of energy. Now, I cynically believe that NASA will still want to send up satellites, because they will have newer, better or just different technology, but the more prosaic satellites like the GPS satellites will benefit from this new technology. Anything that doesn't become obsolete will be able to work up there longer, if not forever. This is probably cheaper than sending up a duplicate, although maybe not, depending on how costly it is to send ASTRO up to refuel another satellite.
