Jet Propulsion Laboratory: Annual Report 2000

Year 2000 began with an intense period of self-examination for the Jet Propulsion Laboratory. Late in the previous year, two Mars-bound missions failed as they were arriving at the red planet, disappointing engineers, scientists and the public at large. After a probing series of internal and external reviews, a redesigned Mars program emerged that is intended to be more robust and more tightly coupled to the questions that scientists are attempting to answer. NASA expressed a significant vote of confidence in JPL by assigning an ambitious project to the Laboratory - to design, build and fly twin rovers to Mars in 2003. Among other missions and research programs, the news was more gratifying. Another Mars orbiter completed its first year of mapping operations, gathering more pictures than those collected over the entire missions of the two Viking orbiters. Stalwart spacecraft such as Galileo continued to deliver scientific discoveries, while a new generation of smaller solar system exploration missions got under way. In Earth sciences, a growing array of spaceborne instruments and satellites gave us new perspectives on the home planet, including an imaging radar mission on the Space Shuttle and two JPL instruments that began science operations after their launch on NASA's Terra orbiter in late 1999. In astronomy and physics, a JPL-built camera continued to perform flawlessly on NASA's Hubble Space Telescope, offering previously unglimpsed views of the deep universe.
