1 eMAS-IR: First Three Test flights (ER-2 809: 22, 28, 30 August 2012) 1.22 Aug: Roll-correction was not enabled for this flight. Some data collected Aug: The Stirling cooler hangs during taxi flight, mission aborted after takeoff. Minimal data collected. 30 Aug: Stirling hangs but remotely re-set; system then operates continuously Demonstrated basic instrument functionality and ground support procedures Remote instrument control via new NASADT/EIP/Iridium system NPP VIIRS Under-flight Ground validation at Tahoe site (radiosondes, VSWIR & TIR radiometers, ASTER SST buoys Links to the quick-looks:

10 Issues to Address: Vacuum integrity (replace valves, O-rings, pumping aparatus) New Helium Leak Detector to deliver ~9/24) Remaining external data ingest: Synchro roll signal (back-up to POS-AV) IRIG-B time code, RS-232, misc. temps and voltages) Scanhead thermal regime Minco Heater operational? excessive cooling from the air-scoop Cryo-cooler shut-down on taxi BB calibration BB#1 reporting cuts off at -30C, which was reached on 8/30 when set to ‘Ambient’) Aeroglaze paint reflectivity measured by JPL 60-Hz noise coupling investigation: Induce vibration externally Inspect power supply, cryo-controller, and grounding circuitry design High Frequency noise in Ports 1 &2 Spectral alignment needed in Ports 1 &2; Gain adjustments in various bands
