Description

In the conquest of space today, it is robots, not humans, who get the glory. This group of NewsHour segments describes missions that represent the foreseeable future in space exploration: sensor-filled craft and remotely operated devices going where men and women 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.
