  2. Fermi Gamma-ray Space Telescope Mission Status S. Ritz

  3. Early Morning, 11 June 2008

  4. Launch! • Launch from Cape Canaveral Air Station 11 June 2008 at 12:05PM EDT • Circular orbit, 565 km altitude (96 min period), 25.6 deg inclination.

  5. A moment later…

  6. And then…

  7. Events • 60-day checkout period went extremely well in all respects. No major outstanding issues. • One 4-minute anomalous event on 31 July caused a LAT turn-off • cause very likely understood, mitigations put into place. reactivation was very quick. • Science operations officially started 14 August • nominal mission is now 2% complete :-) • we’ve come a long way since our last meeting! • Flight Operations Team doing a spectacular job • 2nd LAT FSW update, GBM FSW patch upcoming. Several S/C FSW patches (GPS patch successful), including SSR rewind patch last week. • In sky survey, as planned. Autonomous repoints will start in October, pending LAT & GBM FSW uploads and additional algorithm tuning. • FSSC now releasing LAT ASP results and GBM data

  8. Additional Topics • Reaction Wheel Assembly (RWA) update • Rick Harnden, the Fermi Program Scientist at NASA HQ, will be stepping down in October. Many thanks to him for years of help … and welcome Ilana Harrus! • Conjunction Assessment and Prop system • A time of transitions • most project people have moved on (but we know where they are!). Some are at a reduced level through December. • Others (including Systems personnel) staying on ~full-time to help through December. • Sustaining Engineering work will continue through the mission. • Kevin Grady, Al Vernacchio tying up loose ends, available as needed • Mission Director is Bob Sodano • Mission operations processes are in place • Observatory handover complete. Many thanks to our GD colleagues! • Mission-level public affairs coordination moving to Science Directorate: Frank Reddy (many thanks to Rob Gutro!). Lynn Cominsky (SSU, LAT collaborator, E/PO lead) continues science press functions.

  9. Fellowships • NASA HQ recently decided to consolidate individual mission Fellowships. Fermi+Chandra programs are merged to Einstein Fellowships, administered by CXC at CfA. • Charter Fellows have now started: • Nathaniel R. Butler (Berkeley) • Vasiliki Pavlidou (Caltech) • Uri Keshet (Harvard) • Telecon with Don and Peter and Chip and Josh + Project Science personnel on 27 August • Please give input now on peer panel suggestions!
