Scientists are calling it an "epic result," and NASA announced the news at a press conference today. The success is despite the many twists and turns GP-B has experienced in its long life, from conception in 1959 to its eventual launch in 2004. It required new innovations along the way, including technology that can reduce drag, temperature fluctuations and magnetic influences on orbiting satellites. GP-B technologies are used in GPS equipment and were used on NASA's Cosmic Background Explorer mission, which determined the cosmic microwave background. After finally launching in 2004, GP-B ran out of funding in 2008 before researchers in Saudi Arabia stepped in.
