Time to celebrate!
SORCE in orbit 6 months!


Mission Update –
The days and months have flown by since SORCE was launched January 25th. We certainly have something to celebrate and be proud of! This is a great achievement and everyone is looking forward to a very long and scientifically rewarding mission.
The SORCE team is very pleased with SORCE’s progress to date and they are delighted to be on the way to meeting the mission long-term science objectives. These objectives are: 1) to extend the current 24-year record of TSI measurements, 2) to establish a data set of SSI with daily measurements over the wavelength (color) range from 1 nm to 2000 nm, and 3) to improve our understanding of the Sun’s variability and its effect on our atmosphere and climate.

Spacecraft and Instrument Status –
All spacecraft systems continue to perform exceptionally well. The spacecraft is in its nominal Sun pointing mode, and is making two scheduled ground contacts each day. New experiment commands are up-loaded daily to the spacecraft, and the quality and quantity of solar data continues to expand.
Operating in normal mode, SORCE instruments are making excellent daily solar observations, with nightly stellar observations for calibration. Scientists and engineers continue to verify the instrument calibrations and data processing software. The preliminary data products generated are reviewed as scientists work towards data validation by improving data processing code. This process will continue for months. Data are being distributed to the science community through the Goddard Space Flight Center DAAC.

SORCE Science Meeting
December 4-6, Sonoma, California –

The next SORCE Science Meeting – Physical Processes Linking Solar Variability with Global Change – is scheduled for December 4–6, 2003 in Sonoma, California. The SORCE meeting dates have been selected to accommodate people wanting to attend the AGU meeting, which is the following week in San Francisco.
The meeting will be devoted to our understanding of the physical processes that connect the Sun’s radiation and its variability to our terrestrial environment, including the direct and indirect processes that cause this solar forcing and the mechanisms that cause solar variations. The agenda will consist of both invited and contributed oral presentations and posters, and the Call for Papers will be coming out in early August.
