NASA - National Aeronautics and Space Administration

Who are NASA's Earth Explorers? The elementary school student wondering how El Niño will affect tomorrow's weather. The scientist studying connections between ozone and climate change. And the farmer using satellite pictures to keep track of crops. All of these people are Earth Explorers -- they are all curious about the Earth system. This monthly series will introduce you to NASA Earth Explorers, young and old, with many backgrounds and interests.

After years of dreaming, planning and hard work, NASA's Aura satellite is scheduled to launch later this month. Aura is designed to answer three fundamental questions about our atmosphere:

1. Is the ozone layer recovering?
2. Is air quality getting worse?
3. How is the climate changing?

This month's edition of Earth Explorers introduces you to the professional and personal sides of some of the scientists who have made important contributions to the Aura mission:
