TITLE :Orbiting Satellites Project
WEEK OF :July 28 to August 3, 1994
All spacecraft subsystems performed nominally this week. The power subsystem was reconfigured several times as a result of the science plan taking us from Jupiter to the star Alpha Erindani and then back to Jupiter again. The Jupiter observations required special configurations due to their high antisun and spacecraft roll requirements. All three batteries have shown small differential voltage changes as a result of the reconfigurations, but these were expected and, given their small magnitude, are of no present concern. ATC load testing also continues. The most recent load had four macros with a total of 563 commands. A new GSFC CMS delivery and an EPPS fix should improve the overall testing process in the coming week.
No new problems or incidents to report. Scanner C was turned off, the short wave spectrometer's count rate shutdown value was increased, and the unused sections of the Deep Survey detector were blanked to maximize the science data bandwidth for the Jupiter/comet observation.
EUVE will observe the M dwarf star Wolf 630 until August 7th.
