STATUS:
03.14.08
SPACECRAFT Status
AIM progressed to the normal pointing mode using
an on-board ATS at 17:17 GMT on March 8, 2008 after having
gone into “SAFE hold” on February 7th. All spacecraft
systems are showing nominal operations, and the instruments
were turned back on Friday, March 14th.
INSTRUMENT Status
All instruments have been off the past week
due to the spacecraft “Safe Hold” condition, but
were reactivated Friday, March 14th as part of the recovery
ATS.
The SOFIE instrument operated flawlessly from
turn-on in May 2007 until the spacecraft “SAFE hold”
event on February 7, 2008, collecting nearly 99% of all spacecraft
occultation events. It is now back on as of 16:05 GMT March
14, 2008 and collecting science data. The first public data
release started March 14, 2008 with the release of 2007 May
and June data. Processing of all measurements taken through
February 7, 2008 will be completed by March 15th and the release
of all data up to the Feb 7th “SAFE hold” will
be complete by March 21st. Data products for this release
include temperature, pressure, water, ozone, and methane mixing
ratio profiles, and particulate extinction profiles at 10
wavelengths.
All CIPS data collected through February 7,
2008, when the spacecraft entered “SAFE hold”,
have been processed and examined. The CIPS instrument was
turned back on following the “SAFE hold” event
at 18:06 GMT March 14th. The CIPS instrument has worked flawlessly,
collecting data over the Northern 2007 and most of the Southern
2007/2008 cloud seasons. CIPS data have been cited in many
general publications due to its unprecedented images of Polar
Mesospheric Clouds. CIPS data for the first two PMC seasons
are available on the AIM web site.
The CDE instrument was turned back on
following the “SAFE hold” event at 20:04 GMT March
14th. The CDE data versions for Levels 2 and 3 are being incremented
to version 2. Level 1 will remain at version 1. This version
change will fix a pointing issue in calculating mass as well
as adding an extra parameter to the Level 2 file. This will
take effect on Friday, March 14, when CDE returns to normal
science mode.
