Will wait until results are put together (next week) and paperwork submitted. - Added COMM obtained so that next 2 part maneuver at 240:0228 will be done with real-time contact. Goldstone COMM (DSS-24) now runs from 240:0210 to 240:0800. This COMM period also covers real-time commanding to deploy and insert HETG. - HETG launch lock release and insertion expected to take three hours or less after OBSID 52 is complete (~240:0435) and OBSID changed to 1098. - Added COMM will be requested for HETG retraction to be done via CAP and SAP in real time. 2) Notes on review of P8B load - P8B picks up at 240:0750 3:50am on Saturday, terminating the 1098 observation in the new load at that time. It runs to 242:0456 which includes OBSID 1199, during which time the HETG retraction procedure will be executed in real time via real time commands. - HETG (Herman Marshall) wants to run observation 1199 at best focus, not at a defocus which had earlier been planned. The defocus command is in the load, moving the FA to step +171 at 240:0158. It was decided that the SIM focus would be changed in real time via a CAP. E. Vrem will assist HETG team in writing the CAP, which should be ready for review tomorrow AM.
