Solar Radiation and Climate Experiment

Solar Radiation and Climate Experiment ( SORCE ) is a satellite observatory of NASA, with the influence of the energy radiation of the sun on the climate and the atmosphere of the earth is to be investigated. On 25 January 2003 the 632 kg heavy research satellite was launched with a Pegasus XL. SORCE is part of the Earth Observing System.

SORCE leads the long-term measurements of the total solar radiation by the Earth Radiation Budget and ACRIM instruments on.

Construction

The spacecraft was built by Orbital Sciences Corporation in Dulles, Virginia on behalf of the Laboratory for Atmospheric and Space Physics ( LASP ) of the University of Colorado at Boulder. Is a three -axis stabilized spacecraft having a control system which directs the satellite to the sun and stars to the calibration. The dimensions are in the folded state 100 cm × 160 cm. When the solar panels are folded, the satellite dimensions of 339 cm × 160 cm has. The launch weight of 287 kg. The solar cells provide a power output of 348 watts.
