SIC has two redundant NSSC-Is, only one can be on at a time . SIC has two redundant STINTs (interface units), paired with the NSSC-Is . Redundant unit has been off since launch . SIC has 8 memory units, each with 8k 18 bit words . Either NSSC-I can access full complement of memory . Gathers science data from SIs and forwards on to spacecraft for recording or downlink . Gathers and formats engineering data from SIs and forwards on to NSSC-I and spacecraft . ... Previous slide . ...
... The science from both these missions contributed to three of the Nobel Prizes Giacconi (2002), Mather, and Smoot (2006) - awarded for NASA-based science. ... We encourage NASA to seek new launch capabilities to fill this strategic gap in moderate lift rockets to enable the Explorer program to continue launching missions with significant science payoff but reduced costs and timescales compared to large strategic missions. ... 18 Appendix B: Explorer Missions 1989-present (From PILMSS) No . ...
ST-ECF Instrument Science Report WFC3-2005-17 Ground tests of the WFC3 UVIS grism S. S. Larsen, H. Bushouse, J. R. Walsh March 2005 ABSTRACT The fundamental parameters of a slitless dispersing element are the geometrical configuration of the spectral orders, the dispersion relation relating pixel offset to wavelength and the sensitivity of each order. ... Orders from -8 to +8 are labeled. ... The flux in the -1st order varies between 20% and 60% of that in the +1st order over the wavelength range. ...
