Visit_Comments: Mars will be acquired by blind pointing.  No ACQ is used.  GHRS spectra will be obtained,
                to search for the signature of the CO Cameron band in absorption at 2060A wavelength.  There
                will be two settings of G200M, which overlap in covering the band between 2060 and 2070A.
                The two settings extend the continuum coverage to longer and shorter wavelengths than would
                be possible in a single setting, while optimizing photon collection in the band itself and
                reducing sensititivity to bad diodes within the band.  Note that V for Mars on June 1, 1995
                is given in the target list.
