Doxsey/STScI) 8:00 AM December 8 342:13:00 Summary of recent activities: The EVA crew for today was Kathy Thornton and Tom Akers. The started the EVA at roughly 10:15 pm, they seem to be starting a little earlier each evening. The first task was COSTAR installation. The STOCC commanded the HSP off. The EVA crew opened the aft shroud doors and disconnected the HSP electrical connections. They undid the mounting latches and carefully removed the HSP, the clearances were fairly tight, an inch or two, in some places. The HSP removal went smoothly. They practiced a re-insertion with the HSP and then took it to the temporary parking spot. They then opened the axial SIPE and removed the COSTAR. The COSTAR was then taken over and very carefully installed in the HST. There was no problem with the fit, it went in very smoothly. The latches were fastened and then the connectors fastened. As the crew closed and fastened the doors the STOCC carried out a very short aliveness test of COSTAR, which was successful. The crew had no difficulty closing the aft shroud doors. They then stored the HSP in the axial SIPE and closed it up for return to earth. The next task was the installation of the co-processor. While the EVA crew was getting set up the STOCC safed the SIs and powered down the DF224. The door to the DF224 compartment was opened and the handles removed from the DF224. The co-processor was attached and the connectors between it and the DF224 were mated. The co-processor was firmly fastened and the compartment door closed. The STOCC began the co-processor aliveness and functional tests. After and initial delay due to bad communications links, the tests proceeded and completed successfully. The EVA crew then removed two panels of MLI (multi-layer insulation) from a no longer critical spot in the carrier structures in the payload bay and took them into the cabin when the EVA was completed. Several of the astronauts then used some patterns faxed up from the ground to make two caps for the old magnetometers from the MLI. (On TV it looked a little like a summer camp arts and crafts session). These caps will be installed during EVA 5 and should prevent more pieces from floating away from the old magnetometers. After completing the co-processor tests, the STOCC will recover the SIs from safe and execute the COSTAR functional test. This test exercises several COSTAR functions, including a small motion of the DOB (deployable optical bench). At this point, these activities should be occurring at roughly 9:00 - 10:00. Near-term plans: The orbit re-boost will take place this evening, just prior to the start of the last planned EVA. During this EVA the SADE-1 will be replaced, the GHRS redundancy kit will be installed, the magnetometer caps will be installed, and the solar arrays will be deployed.
