Jebel Uweinat (1,934 m, "mountain of sourcelets") is a mountain range in the area of the Egyptian-Sudanese-Libyan border. In general, the west slope constitutes an oasis, with wells, bushes and grass. The area is notable for its prehistoric petroglyphs. Updated on 1/8/2013
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging
instrument onboard Terra, the flagship satellite of NASA's Earth Observing System
(EOS) launched in December 1999.
ASTER is a cooperative effort between NASA, Japan's Ministry of Economy, Trade
and Industry (METI), and Japan Space Systems
(J-spacesystems). ASTER data is used to create detailed maps of land surface temperature, reflectance,
and elevation. The coordinated system of EOS satellites, including Terra, is a major component
of NASA's Science Mission Directorate and the
Earth Science Division.
The goal of NASA Earth Science is to develop a scientific understanding of the Earth as an
integrated system, its response to change, and to better predict variability and trends in climate,
weather, and natural hazards.
