THEMIS MISSION PRE-SHIP REVIEW ESA C. Carlson, M. Ludlam, J. Mc. Fadden University of California - Berkeley MPSR ESA- 1 UCB, Oct 26, 2006
Overview • Instrument Status • Problem Failure Reports • Calibration Data MPSR ESA- 2 UCB, Oct 26, 2006
Instrument Status MPSR • All ESA instruments are fully functional • There are no outstanding issues or problems for the ESA. • ESA survived the environmental tests and is ready for launch. ESA- 3 UCB, Oct 26, 2006
Problem Failure Reports 4 PFR’s raised since last review – all are GSE/script/commanding related – i. e. not instrument related. PFR 212 – Radiation source not correctly installed during F 3/F 4 Probe Thermal Vacuum. Source was installed the wrong way round. ESA HV check out was still possible without the source. Problem was corrected for the F 5/F 1 Thermal Vacuum test. CLOSED. PFR 213 – No 459 (Electron Burst Rate) Data being received during functional test whilst in Thermal Vacuum. Tracked down to a script error. Script corrected and re-run and verified that 459 was received. CLOSED. PFR 214 – Readback problem with MCP Housekeeping. At nominal setting the MCP HV supply incorrectly read full scale. Traced to a problem in the ITOS database calibration for this value. CLOSED. PFR 220 – Energy tables not written correctly. During the uploading of the tables there were some commanding issues with the probe. The script was re-run from the beginning and problem was corrected. Tables were not reloaded for a full thermal vacuum cycle and no data corruption was seen. CLOSED. All previous ESA PFRs closed. MPSR ESA- 4 UCB, Oct 26, 2006
