66 -- EARTH SCIENCE SYSTEM PATHFINDER PROGRAM POC Mark M. Jarosz, (301)286-2421. Remote-sensing mission to measure climate forcings and feedbacks. This is a notice of intent to issue an RFI for the Earth Science System pathfinder program. The initial concepts for ESSP are available on the Internet at http://www.hq.nasa.gov/office/mtpe/esspcbd.html. This effort is focused on high-priority Earth science not already addressed by ongoing planned missions. The proposal will focus on a low-cost mission, including instruments, spacecraft, a launch vehicle, ground station, and two years of mission operations to measure the reflected solar spectrum (radiance and polarization) and the thermal infrared spectrum with sufficient precision to allow the determination of climate forcings and feedbacks. The remote sensing mission would include measurements of aerosols and clouds. The soliciation's release is planned for May 17, 1996. Electronic versions of the documents will be provided on the World Wide Web at http://genesis.gsfc.nasa.gov/procure.htm, and by anonymous ftp to genesis.gsfc.nasa.gov/public/solicita. (0134)
