Mission Sim 1 This was the first of the Mission Simulations. It executed during the first week in December, 2001. Only two instruments were available on the spacecraft at the time of this mission simulation: CFI and the NGIMS brassboard. We constructed a very simplified encounter sequence as the primary instrument test. See the file msim1_seqdescription.asc for a brief outline of the CFI imaging in this test. See the file msim1_ops_overview.msw for an operations overview of the entire mission simulation I. An overview of the results of the test is available in /harch/meetings/ sciteammtg_011502.pdf.
