On Dec. 18, 1999, NASA launched Terra, the first of three flagship missions in NASA's Earth Observing System, to examine the interactions between Earth's ocean, atmosphere and land. In the decade since, Terra's five instruments-from the United States, Japan and Canada-have contributed to our understanding of how Earth is changing and what the consequences of those changes are for life on Earth.

Terra researchers are presenting their latest results at this year's fall meeting of the American Geophysical Union in San Francisco. To see a sampling of their latest findings, visit: http://www.nasa.gov/mission_pages/terra/news/decade-orbit.html .

To read highlights of some of the significant changes Terra has observed over the past decade, see: http://terra.nasa.gov/Ten/.

JPL built and manages Terra's Multi-angle Imaging SpectroRadiometer, or MISR, a unique imaging system that collects images from nine widely-spaced angles to study many different phenomena on Earth's surface and in its atmosphere. For more information on MISR, see: http://www-misr.jpl.nasa.gov/.

The Japanese-built Advanced Spaceborne Thermal Emission and Reflection Radiometer, or ASTER, instrument on Terra obtains high-resolution global, regional and local images of Earth in 14 color bands and is the only high-resolution instrument on Terra. JPL is responsible for the American side of the joint U.S.-Japan ASTER Science Team. For more information on ASTER, see: http://asterweb.jpl.nasa.gov.
