Contract GSFC0199703DNAS597045

Description

This Effort Is the Extension of the Definition Phase (Phase B) for the Earth Observing System (Eos) Solar Stellar Irradiance Comparison Experiment (Solstice). The Output of the Phase B Extension Will Be a Conceptual Design Cost Review (Cdcr). The Statement of Work Is Broken Down Into Three Sections: Instrument, Science, and Science Computing Facility. This Is a Principal Investigator (Pi) Experiment to Make Long-Term Solar Observations with the Eos Solstice Instrument. The Measurements Will Contribute to an Improved Understanding of the Variable Energy Input to the Earth's Atmosphere with Special Emphasis on the Sun's Influence on the Temperature, Structure, Dynamics and Chemistry of the Atmospheric System. A Fundamental and Specific Use of Eos, Representing a Substantial Change from Past Practice, Is the Production and Archiving of Data Sets for General Scientific Use. These Data Sets Will Contribute to the Construction of Interdisciplinary Science Products. This Effort Will Include Management of the Complete Program and Its Coordination. IN Phase C/D/E, the University of Colorado (Uc) Shall Provide the Facilities, Materials, Services, and Personnel Necessary to Continue the Sorce Mission. Uc Shall Be Responsible for Mission Operations and Shall Be Responsible for the Safety of the Instruments and the Spacecraft Bus Through a Subcontract Arrangement with the Spacecraft Provider (Orbital Sciences Corporation). Uc Shall Develop/Maintain Algorithms for Producing the Science Data Products as Proposed and Approved by NASA Hq. After the Science Products Have Been Validated, These Products Will Be Transferred to the Gsfc Data Achieve for Achieve and Distribution. The Ground System Used in the Sorce Mission Shall Meet All NASA Security Requirements.
