Doug Peterson Johnson Space Center, Houston, TX (Phone: 281/483-5111) October 26, 1998 Jennifer McCarter Headquarters, Washington, DC (Phone: 202/358-1639) RELEASE: 98-197 CREW MEMBERS NAMED FOR EARTH-MAPPING MISSION An international cadre of astronauts will support an ambitious mission to map the EarthÕs surface when Endeavour launches on the STS-99 mission in September 1999. Commander Kevin Kregel; Pilot Dom Gorie; and Mission Specialists Janet Kavandi, Ph.D.; Janice Voss, Ph.D.; Mamoru Mohri, Ph.D. (NASDA); and Gerhard P. J. Thiele (ESA) have been named to the Shuttle Radar Topography Mission (SRTM). SRTM evolved from the two 1994 Space Radar Laboratory missions, which collected data on geology, geography and oceanography. During the mission, the crew will use specialized radar equipment and other electronics to map 80 percent of the EarthÕs land mass, extending from the southern tip of Greenland to the northern edge of the Antarctic Circle. Data targets will be spaced approximately every 90 feet and the resulting image should be accurate to within 30 feet of the height of the terrain. Kregel was selected as an astronaut in 1992. He has logged more than 41 days in space during three missions: as pilot of STS- 70 in 1995 and STS-78 in 1996, and as commander of STS-87 last year. After being selected as an astronaut in 1994, Gorie served as pilot earlier this year on STS-91, the ninth and final Shuttle-Mir mission of the U.S.-Russian Phase One Program. Kavandi was selected as an astronaut in 1994 and flew on board Discovery earlier this year with Gorie on STS-91. Voss will be making her fifth space flight on STS-99. She has flown previously on STS-57 in 1993, STS-63 in 1995; and STS-83 and STS-94 in 1997. Mohri, of the Japanese Space Agency, is a member of the 1996 astronaut class. STS-99 will be his second space flight; he flew as a Payload Specialist on STS-47, the Spacelab-J mission, in 1992. Thiele, of the European Space Agency, is a member of the 1996 astronaut class. This will be his first flight. For additional information on the STS-99 crew, or any astronaut, see the NASA Internet biography home page at URL: http://www.jsc.nasa.gov/Bios/ -end-
