A -- TOTAL SOLAR IRRADIANCE MISSION SOL AO-97-MTPE-01 DUE 112197 POC Robert Schiffer, Atmosoheric Science Program Manager, Phone (202)358-1876, Fax (202)350-2770, Email robert.schiffer@hq.nasa.gov WEB: Click here for the latest information about this notice, http://procurement.nasa.gov/EPS/HQ/date.html#AO-97-MTPE-01. E-MAIL: Robert Schiffer, robert.schiffer@hq.nasa.gov. The National Aeronautics and Space Administration (NASA) announces the release of the Announcement of Opportunity for NASA s Total Solar Irradiance Mission (TSIM). The purpose of the announcement is to solicit a TSIM Principal Investigator and Mission Team. The TSIM will be part of NASA s contribution to the joint NASA-CSA SciSat Mission. SciSat will consist of two small science satellites, one from each agency, launched together in December 2001. The TSIM objectives are to continue the precise, time-series measurement of the Total Solar Irradiance and, optionally, provide two spectral irradiance measurements (200-300nm and 1500nm) required by the National Polar-orbiting Operational Environmental Satellite System (NPOESS). Utilizing the new MTPE PI-Model for mission management, the TSIM team selected will be responsible for conducting the end-to-end mission including design and development of the TSIM instruments, acquisition of a TSIM spacecraft, development of scientific algorithms to be used to produce geophysical parameters from the TSIM data stream, command and control of the TSIM spacecraft for five years, and the production, preservation, and distribution to the general public of all TSIM science data products. This AO will be available electronically on September 16, 1997 via the Internet at the Mission to Planet Earth Home Page: ttp://www.hq.nasa.gov/office/mtpe/ under MTPE Research Announcements or via anonymous ftp at: ftp.hq.nasa.gov/pub/mtpe. Paper copies of the AO will be available to those who do not have access to Internet by calling (202) 358-3552 and leaving a voice mail message. Please leave your full name and address, including zip code and your telephone number, including area code. Questions regarding this AO can be addressed to NASA Headquarters, Code YS, Washington, DC 20546 Attn.: Dr. Robert Schiffer, Fax Number: 202-358-2770, e-mail: (Internet) obert.schiffer@hq.nasa.gov; or to Goddard Space Flight Center, Code 170, Greenbelt, MD 20771 Attn.: Ms. Vanessa Griffin, Fax Number: 301-286-1671, e-mail: Vanessa.L.Griffin@gsfc.nasa.gov. This announcement will be open for the period September 16, 1997 through November 21, 1997, and proposals may be submitted at any time throughout that period. (0238)
