More than 400 miles above Earth, a satellite the size of a school bus is earning its frequent flyer miles. On Oct. 6, NASA’s Terra completed 100,000 orbits around Earth. Terra, which launched Dec. 18, 1999, is projected to continue operation into the 2020s.

For the first time ever, measurements from NASA Earth-observing research satellites are being used to help combat a potential outbreak of life-threatening cholera. Humanitarian teams in Yemen are targeting areas identified by a NASA-supported project that precisely forecasts high-risk regions based on environmental conditions observed from space.

Dr. John C. Gille applies his training as a physicist to the development and use of satellite instruments to measure and track pollutants, greenhouse gases, and other chemicals in the lower and middle atmosphere. He is the U.S. principal investigator for MOPITT, an instrument flying aboard NASA’s Terra spacecraft that measures the global distributions of carbon monoxide. By understanding the sources and behavior of carbon monoxide, scientists can also gain insights into a number of other pollutants. In addition, Gille is the U.S. principal investigator for HIRDLS, an instrument on NASA’s Aura satellite that scientists use to study such topics as the recovery of the ozone layer and the impact of greenhouse gases on climate. Gille is a researcher in NCAR’s Atmospheric Chemistry Division.
