NASA is building 3 specialized tracking stations to record the wideband radioastronomy data that this spacecraft will produce. Multiple penetrator mission to study the crust structure and thermal construction of the moon's interior. NRAO is building similar ground stations for tracking. These two spacecraft will coobserve radio sources in conjunction with ground based VLBA radio telescopes. Separate orbiter and lander missions continuing the Mars Surveyor program.
Mars orbiter to observe interaction between Martian atmosphere and the solar wind.
Small Explorer mission to survey starburst galaxies, where star formation is taking place at a high rate. High resonance and sensitivity X-ray astronomy. Stardust will collect cometary dust and volatiles as well as interstellar dust, returning samples to Earth in 2006. Asteroid rendezvous and sample return. Proposed new start in FY 1998.
