Negotiated locations of ACIS operational and survival heaters with members of ISIM Thermal Tiger Team. The heaters were moved from the -Z wall of the SS to the +Y and -Y walls of the SS. The new locations reduce the overall thermal gradient from the heaters to the coldest DEA/DPA box walls and preclude the survival heaters turning on during a 2-hour eclipse.
The completion of the stress analysis CDRL continues to be delayed as a result of more tasks assigned related to tiger team activities and action items. Heavy ACIS Tiger Team activities have required significant effort to support the PSMC base plate redesign. In addition, the delayed stress analysis now overlaps with the scheduled GSE drawing review and associated analysis which causes additional delays. These delays are not considered critical since no stress concerns have arisen and all components analyzed to date continue to show significant positive margins.
