This paper will describe the scope and the state of the JPL MUSES CN rover design. The following topics will be included: 1) rover system description and its intended operations on the surface of the asteroid, 2) rover electrical subsystems and 3) rover mechanical subsystems.
A new remote sensing instrument, the Submillimeterwave Limb Sounder, has been developed to simultaneously measure ClO, HCl, O3 and HO2 from high altitude balloon and aircraft platforms. The instrument is a double sideband heterodyne radiometer measuring atmospheric thermal emission spectra near 640 GHz from the Earth's limb. The instrument was flown in April and October, 1991 and in February, 1992 on high altitude balloon platforms over the southwestern United States.
The vertical profiles of ClO, HCl, HO2, and O3 were determined from thermal emission measurements by a balloon-borne spectrometer operating near 640 GHz. Results are in broad agreement with previous measurements and models, but differ significantly with model photochemistry for the ratio of ClO to HCl.
