Science Meeting Summary
A
meeting summary, extended abstracts, and
select presentations will be available soon at: http://lasp.colorado.edu/sorce/July02ScienceMeeting.html.
At
the end of the meeting Tom Woods summarized the relevance
of the discussions to SORCE. There were three aspects of
the discussions that are connected to the SORCE program:
validation of the solar irradiance time series, solar irradiance
modeling, and atmosphere/climate modeling. A summary of
these connections as grouped by the SORCE instruments is
below. The EUV region, which is not measured by the SORCE
instruments, and thus not listed, will be measured during
the SORCE mission by the TIMED Solar EUV Experiment (SEE).

Tom
Woods summarizing the SORCE Working Group Meeting.
The
SORCE team is planning to have another science meeting shortly
after the December launch to discuss initial results and
data validation. Next summer the SORCE science working group
will meet for more in-depth scientific discussions.
SORCE
Mission Status
The
month of July has been extremely busy with continuous Environmental
Testing to make sure the SORCE spacecraft is prepared to
tolerate the actual launch and survive in the mission environment.
Tests completed in July include vibration, acoustic, and
pyro-shock separation system. In addition the Solar Array
Panel Illumination tests were successfully completed, as
well as a Flight Software upgrade to version 6.0.
The Thermal Vacuum test is the final major test to be completed.
After a final inspection the Vacuum Chamber doors will be
closed on August 2, and the pumpdown will begin. The Instrument
Module will undergo tests in this special environment for
three weeks. Details will be included in the August SNS
Newsletter.
Countdown
to Launch - December 1
(as of July 30, 2002)
Orbital's
Pegasus XL will launch SORCE into space.
