      The RHESSI mission consists of a single spin-stabilized
      spacecraft in a low-altitude orbit inclined 38 degrees to
      the Earth's equator. The only instrument on board is an
      Germaniun imaging spectrometer with the ability to obtain high
      fidelity solar images in X rays (down to 3 keV) to gamma rays (1 MeV).
  
      RHESSI provides an angular resolution of 2 arcseconds at
      X-ray energies below ~40 keV, 7 arcseconds to 400 keV,
      and 36 arcseconds for gamma-ray lines and continuum above 1 MeV.
  
      RHESSI was launched on 5 February 2002.
