STScI Integrated Scheduling System

Bench Timing Testing of Phases 1-5 completed (T. Wheeler)

––Essential for SMGT-readiness certification

––Target Acquisition FSW component not yet tested

––Unique Timing SMS and Reconfiguration SMS-suite

>>FUV and NUV completed successfully

––STScI Commanding Certification SMS

>>NUV completed successfully

>>FUV Commanding Certification identified minor issue

••Hand-edited SMS ran successfully

>>FUV testing requires FUV detector ETU

>>Will re-test remotely (including Target Acquisition) within 6 weeks

––Testing and results are very positive!

STScI Thermal-Vac Support

STScI Coordination with IDT (STScI lead: Sembach)STScI Coordination with IDT (STScI lead: Sembach)

OPUS support of Thermal-VacOPUS support of Thermal-Vac

––MOU requires STScI to deliver T-Vac version of OPUS two months inadvance of T-Vac – on-track

>>Require test (simulator) target acquisition images 2-4 weeks in advance of thisdate if OPUS delivery is to include target acquisition functionality

>>Minor T-V logistics issues being worked (e.g., additional k/w)

>>Coordination ongoing with IDT – all nominal

STScI Staffing Support at T-VacSTScI Staffing Support at T-Vac
