Deep Space 2 is part of NASA's New Millennium Program, which develops cutting-edge technology and flight tests it to reduce the risk for future missions. Since DS2 probes' contain first-of-a-kind instruments and systems, "just getting them to the launch pad was a measure of success," said Gavit. Review boards will be set up within NASA and JPL to study the cause of the apparent loss and explore ways to prevent a recurrence.
