The Solar Probe mission will be developed under the NASA Outer Planets Program using X-2000 system technology. The present design uses non-nuclear power systems, with the prime mission from 0.5 AU on the inbound pass, to a perihelion of 4 R-s, to 0.5 AU on the outbound pass. A full complement of both in situ and remote sensing instrumentation will be flown, including high resolution disk imaging, These high-technology lightweight instruments have been partially developed under a NASA NRA program and NASA PIDDP funding. The data rates will be greater than 100 kbps over the solar poles.
