In the conquest of space today, it is robots, not humans, who get the glory. Describes missions that represent the foreseeable future in space exploration: sensor-filled craft and remotely operated devices going where people can't. The program features Deep Impact, a comet-blasting probe; Cassini-Huygens, pioneer of Saturn's moon, Titan; Robonaut, a machine designed to perform human tasks; Ranger, a huge mechanical spider that could conceivably repair the Hubble Space Telescope; the Hubble itself, aging but carrying on; and the planned Webb Space Telescope, Hubble's eventual successor on the vanguard of deep-space science.
