Task Outcome Summary

Abstract

This task powered-on the CE (CE_OFF_BOOT) and then performed the state transitions (CE_BOOT_OPR, MIPS_OPR_MRDY, MIPS_MRDY_MOBS) to bring MIPS to the Observe state. A thermal anneal was performed on the 24 µm array, and temperature data saved via a dump-diagnostic-data command. The temperature curves in this campaign (B) were different from those seen in Campaign A1 because teh conductance of the MIPS baseplate was lower in B due to the lower baseplate temperature. Temperature data from the anneal performed at the end of Campaign B (mips-990) are also presented here.

Analysis

Confirmation of the success of the state transitions was done by monitoring the real-time telemetry from the spacecraft on the DMD screens at the SSC. No unexpected errors were generated during these transitions, confirming succesful entry into Observe state. Temperature data during the 24 µm anneal were collected. These were converted to engineering units (K), and plotted as a function of time. Tables of minimum, maximum, and temperature change are also generated.

Results

The following are binary data files, temperature plots and tables of temperatures for each of the anneals:

MIPS-990 Anneal Results

Conclusions

The Campaign B turn-on of the CE and MIPS was succesful.

The MIPS thermal anneal heaters continue to behave nominally. There have been slight changes in the thermal conductances in the area covered by the MIPS temperature sensors since campaign A. Temperatures during the two 24 µm anneals in Campaign B were nearly identical with each other.

Output and Deliverable Products
