AIM continues to operate smoothly. All of the systems are nominal and we have had daily periods of uplink receiver bitlock. The work on the Relative Time-tagged Sequences made significant progress this week as we continue to improve spacecraft autonomous operations. After a thorough review by the flight team, these sequences are loaded into our ground computer and transmitted to the spacecraft whenever we experience bitlock.
The SOFIE instrument is working perfectly and autonomously with all engineering and science parameters remaining within their nominal range. 100% of science measurements are being transmitted and ingested into the SOFIE data system. Level 2 data is now released through March and level 1 data through April 8.
The SOFIE cosmic smoke data analysis continues, including the removal of contaminant ozone absorption from band 3. The results have been processed for 2007 in both hemispheres and compared to model results. Presentations covering the latest SOFIE PMC and smoke results were given at the recent AIM science team meeting.
CIPS continues to provide excellent science data from all four cameras. Further, our analysis of on-orbit calibration data shows that camera sensitivity has changed less than 0.5% since launch. CIPS data sequencing automatically switched from the Southern to Northern Hemisphere on the first day of spring, as planned
CDE is on and collecting dust impact data following the completion of the Recovery ATS. Temperatures and voltages are nominal. CDE Version 2 data processing is being implemented for Levels 1 (Charge) and 2 (Mass).
AIM Science Team Meeting
The AIM Science team met April 14-16 at Hampton University.
Presentations included a status of the spacecraft operations and
autonomous capability, the instrument operations and data processing,
and the ongoing science investigations. In addition a “data access”
workshop was held including presentations by LASP and GATS
representatives and Hampton University students developing data search
and access tools.
AIM Receives NASA's Group Achievement Award
The AIM team has been selected to receive a NASA’s Group Achievement Award “For outstanding achievement in developing and launching the Small Explorer mission to study the phenomena of polar mesospheric clouds.” Dr. Russell, the principal investigator, will accept the award on behalf of the team May 8th during the 2008 Agency Honor Awards Ceremony at NASA Headquarters.
