Earth Observing System (AURA)

Earth Observing System (EOS) Aura is a NASA mission to study the Earth's ozone, air quality and climate. This mission is designed exclusively to conduct research on the composition, chemistry and dynamics of the Earth's upper and lower atmosphere employing multiple instruments on a single satellite. EOS Aura is the third in a series of major Earth observing satellites to study the environment and climate change and is part of NASA's Earth Science Enterprise. The first and second missions, Terra and Aqua, are designed to study the land, oceans, and the Earth's radiation budget. Aura's chemistry measurements will also follow up on measurements which began with NASA'S Upper Atmospheric Research Satellite and continue the record of satellite ozone data collected from the TOMS missions.

The EOS Aura satellite, instruments, launch, and science investigations are managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland. The satellite will be launched in January 2004 and operated for five or more years. Scientific investigations will continue throughout the years the spacecraft is in operation and several years afterwards.

This site provides information on the mission's science objectives, spacecraft and instrument technology, mission operations, and data analysis. Aura project management is described with useful information on conducting business with the project. Recent milestones and events of interest are also posted. There are many links relating to atmospheric chemistry research and related spaceflight projects in the United States and the rest of world.
