  1. SIERRA Payload Preliminary Design Review Lesli Monforton NASA ARC BAER Institute July 17, 2008

  2. SIERRA NosePayloads • Primary Payload: NASA ARC; Hyperspectral – Stephen Dunagan • Piggyback Payload 1: NASA Wallops FRC; Microspectrometer – Geoff Bland • Piggyback Payload 2: University of Colorado; Laser - James Maslanik Laser • Additional Instrumentation: NASA ARC; CMIGITS III - Paul Bui

  3. Hyperspectral Payload Stephen Dunagan • Specim ImSpector • Imperx Camera • Data System • Data Disk

  4. Nose Layout Notes • Upper Shelf - Vibration Isolated (Lord 150APL Series Mounts) 1/8 7075 T6 • Lower Shelf - Vibration Isolated (Lord 150APL Series Mounts) 1/8 7075 T6 • CM3, HMR 3000 require Hard Mounting • Also directly mounted: GPS Antenna, Microspectrometer Lenses, K&Z Pyrometers-All to Top or Bottom Skin of Nose • All Drawing do not show Fiberglass Skin & Aeromat Thickness for Clarity
