The timeline below contains the most up-to-date information RE: the HST Jupiter campaign's mission timeline and predicted impact times of each P/SL9 fragment [based on Chodas, Yeomans, et al.]. (1) HST orbit since January's SOT meeting Using the most recent HST ephemeris supplied by Dave Taylor (SPSS), all orbit visibility periods occur approximately 7 minutes earlier (than based upon the information available at the SOT meeting). This "slip" does not affect the currently planned science for the Jupiter campaign. However, the following orbits graze SAA contour 5 (this was not known at the time of the January SOT meeting): orbit 87 202:06:02 -- 3 min Hammel WFPC 102 203:06:09 -- 2 min Hammel WFPC 117 203:06:17 -- 1 min Hammel WFPC (2) Delta_t_tot Changes for Impact Times (since Jan.

day 197 is July 16. All times are UT (at Earth). Orbit times are from the extrapolation done on Feb 4, 1994. Impact times are from the 1 Feb. JPL posting. All times subject to change due to uncertainty in extrapolation of HST's orbit and in prediction of impact times. Note that FGS control cannot be used between 197:06 and 198:13, due to the proximity of the Moon. Each orbit (visibility period) lasts 52 min. In the SAA duration column, ending time labeled "end" means it lasts until the visibility period of the HST ends. The numbers of the orbits here are rather arbitrary. Orbit # 1 here corresponds to orbit No. 23031 from HST's numbering convention.
