Federal courts can sometimes hear cases arising under state law pursuant to diversity jurisdiction , state courts can decide certain matters involving federal law, and a handful of federal claims are primarily reserved by federal statute to the state courts. Both court systems have exclusive jurisdiction in some areas and concurrent jurisdiction in others. The U.S. Constitution safeguards judicial independence by providing that federal judges shall hold office "during good behavior"; in practice, this usually means they serve until they die, retire, or resign. A judge who commits an offense while in office may be impeached in

Several redesigns to reduce cost were conducted in the early 1990s, stripping away much of its functions. Despite calls for Congress to terminate the program, it continued, in large part because by 1992 it had created 75,000 jobs across 39 states. By 1993, President Bill Clinton attempted to significantly reduce NASA's budget and directed costs be significantly reduced, aerospace industry jobs were not lost, and
