Date: Mon, 19 Aug 2002 19:04:11 -0400 From: Kimberly Strong To: MANTRA email list Subject: MANTRA 2002 - Monday, August 19 Status MANTRA 2002 - Monday, August 19 Status Greetings from Vanscoy, New arrivals today - Stephen Brown from York U Pointing System - hardware all in place, reaction wheel rotates gondola - four serial data ports are now working (allows two for MAESTRO-B) - mechanical and electrical integration to gondola complete - need to do integration/test with SPS-B1, MAESTRO-B, and MSC FTS - need to modify software to integrate reaction wheel and set up automation of measurements MSC SunPhotoSpectrometers (SPS-B1, SPS-B2) - mechanical and electrical integration complete - transient current spike was measured - don't appear to need modifications to power supplies for flight instruments - working on covers for power supplies - need to insulate power supplies and instruments - absolute and wavelength calibration on August 20 MAESTRO-B - still investigating at noise issue, but getting signal - integration planned for today - need to make lid and insulate, and do calibration U of Denver FTS - mechanical and electrical integration complete - needs alignment, then solar measurements to test detector alignment and set gains MSC FTS - need to modify software to use 19200 kbaud line and to check downlinked data packets (~1 day) - need to do alignment (1-2 days) - need to do solar scan and set gains (~1/2 day) - need to do electrical integration and integrate with pointing system (~1/2 day) - SIL to add third contact closure to enable turning off FTS while downloading data (~30 minutes/scan to downlink) - considering addition of new system to monitor thermistors, voltages, and FTS test points, time permitting MSC OH Spectrometer - now working again with new version of software and new memory - need to complete electrical integration (data) - planned for today - needs alignment and focussing - decided to move the OH mount on the gondola to ensure correct azimuth pointing, so no need to add sun sensor MSC Emission Radiometers - mechanical and electrical integration complete - calibration done today, went well - need to make covers for viewports, check preflight LN2 fill Service d'Aeronomie SAOZ - made sunset direct sun and zenith sky measurements yesterday and did mercury lamp test today - ready to fly - SIL to test harness for mounting on flight train today - need to check for interference between GPS antenna and upper CIP Ozonesondes - no flight today Ground-based MSC Brewer - continuing direct sun measurements Ground-based York U AOTF spectromter - set up, new wooden housing complete, almost ready to start measurements Ground-based U of T zenith-sky spectrometer - continuing zenith-sky measurements - investigating scattered spikes in CCD signals - yet to set up telescope for night-time observations Ground-based MSC SPS-G - set up on roof today, tracking the sun, should start measurements tomorrow Overall schedule: Monday August 19 - should complete payload integration, except MSC FTS August 20 or 21 - mechanical and electrical integration of MSC FTS Tuesday August 20 - test SPS-B1, MAESTRO-B, MSC FTS with pointing system Weds. August 21 - instrument alignment/calibrations with sun, RFI test Thursday August 22 - hanging test with crane (morning) Thursday August 22 - dry run (9 PM to 1 AM) Saturday August 24 - flight ready All for now.
