Spacecraft Overpass Predictions are now available for the Earth Observing satellite fleet and many other objects on-orbit!
TRACK Earth Observing satellites with NASA/MSFC's J-Track utility. We're currently tracking Terra, Landsat-7, TRMM, OrbView-2 (SeaSat), and QuikSCAT.

A Delta 7320-10 carrying the EO-1 and SAC-C spacecraft lifted off from Vandenberg Air Force Base at 1:24 pm EST on November 21, 2000. After deployment from the second stage of the Delta, EO-1 will fly in a 705 km circular, sun-synchronous orbit at a 98.7 degree inclination. It will follow along Landsat 7's ground track one minute behind Landsat 7, and will demonstrate new remote sensing technologies.

The ICESat spacecraft carries a Geoscience Laser Altimeter System (GLAS) for measuring the elevations of ice sheets as well as changes in their elevations over time. The GLAS sensor also measures height profiles of clouds and aerosols, land elevations, vegetation cover, and approximate ice thickness. The mission is mainly designed to help scientists understand and predict how ice sheets and future sea levels will change as Earth's climate changes.

Earth scientists will move a step closer to a full understanding of the Sun's energy output when NASA launches the Solar Radiation and Climate Experiment (SORCE) satellite on January 25, 2003. SORCE will be equipped with four instruments that will measure variations in solar radiation much more accurately than anything now in use and observe some of the spectral properties of solar radiation for the first time. With data from NASA's SORCE mission, researchers should be able to follow how the Sun affects our climate now and in the future.
