Managed for NASA by the California Institute of Technology, JPL is the leading U.S. center for robotic exploration of the solar system.

Seeks to study the sea surface height. Maintaining a database of ocean surface topography can help predict short-term changes in weather and longer-term patterns of climate.

The primary objective is to support the ASTER and MODIS instrument teams in the areas of algorithm development, calibration and validation.

A high resolution imaging instrument that is flying on the Terra satellite. Obtains detailed maps of land surface temperature, emissivity, reflectance and elevation of the Earth.

An autonomous celestial observatory developed by the Jet Propulsion Laboratory and funded by NASA to study asteroids and comets. The facility is a cooperative effort between the NASA Jet Propulsion Laboratory and the United States Air Force designed to complete a comprehensive search of the sky for near-Earth asteroids and comets.
