E-MAIL: Peter Ahlf, peter.ahlf@hq.nasa.gov. The National Aeronautics and Space Administration's (NASA's) Human Exploration and Development of Space (HEDS) Enterprise solicits proposals for investigations to be carried to the surface of Mars by the MSP 2003 Lander Mission. These investigations will require instrumentation to be developed and placed on a fixed lander platform in order to address scientific investigations of the radiation environment; soil, dust, and environmental interactions; and fundamental biology. Instruments will also be solicited to demonstrate in-situ resource utilization technologies. These investigations will be carried out in addition to the primary Space Science Enterprise mission objectives for Mars sample return. NASA also announces an opportunity to propose definition studies for the mission opportunities in 2005. These opportunities include lander investigations similar to the 2003 opportunity, micromissions, and a dedicated HEDS lander mission. These definition studies should address potential flight experiments for HEDS specific Mars exploration goals. This solicitation is open to U.S. and foreign proposers in all categories of governmental and private sector organizations, agencies, and institutions. It will be open for the period through August 10, 1999. Proposals may be submitted at any time throughout the period. This solicitation will be available electronically via the Internet at http://peer1.idi.usra.edu/peer_review/nra/nra.html on June 18, 1999. Paper copies of the Announcement are available after June 18, 1999 to those who do not have access to the Internet by calling 202-358-4180 and leaving a voice mail message. Please leave your full name, address with zip code and telephone number with area code and the AO you are requesting (AO 99-HEDS-01). The technical point of contact for this effort is: Peter Ahlf, Life Sciences Division, Code UL, NASA Headquarters, Washington, DC 20546. This notice constitutes a NASA Announcement of Opportunity as contemplated in FAR 6.102 (d) (2). Proposal due date is August 10, 1999. Posted 06/02/99 (D-SN337897). (0153)
