Together with the entire fleet of EOS spacecraft, Terra is helping scientists unravel the mysteries of climate and environmental change. TERRA's data collection instruments include: Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Clouds and the Earth's Radiant Energy System (CERES), Multi-angle Imaging Spectro-Radiometer (MISR), Moderate-resolution Imaging Spectroradiometer (MODIS), Measurement of Pollution in the Troposphere (MOPITT)
Finding planets orbiting nearby stars has been a holy grail in astronomy for more than 400 years. We began working on this problem 30 years ago, at a time when there were no known extrasolar planets. In late 1995 we began routinely finding planets around the nearest stars. Since then we have found several hundred planets, including the first sub-saturn mass planet, the first neptune mass planet, the first terrestrial mass planet, the first multiple planet system, and the first transiting planet.

The POES satellite system offers the advantage of daily global coverage, by making nearly polar orbits 14 times per day approximately 520 miles above the surface of the Earth. The Earth's rotation allows the satellite to see a different view with each orbit, and each satellite provides two complete views of weather around the world each day. NOAA partners with the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) to constantly operate two polar-orbiting satellites – one POES and one European polar-orbiting satellite called Metop. NOAA's Polar Orbiting Environmental Satellites (POES) carry a suite of instruments that measure the flux of energetic ions and electrons at the altitude of the satellite. This environment varies as a result of solar and geomagnetic activity. Beginning with the NOAA-15 satellite, an upgraded version of the Space Environment Monitor (SEM-2) has been flown.
