Scientists sue NASA, Caltech over deep new background checks

Jet Propulsion Laboratory scientists and engineers sued NASA and the California Institute of Technology on Thursday, challenging extensive new background checks that the space exploration center and other federal agencies began requiring in the wake of the Sept. 11 terror attacks. The lawsuit was filed in U.S. District Court in Los Angeles by 28 plaintiffs. Many have worked on such projects as the Mars rovers, the Galileo probe to Jupiter and the Cassini mission to Saturn, but none are involved in classified work, according to the suit. It seeks class-action status to represent similar JPL employees.
