Start with History
Thousands of employees.
NASA has people all over the Earth working to study our planet and the worlds around it, from climate science to supernovae.
NASA's Earth Observing System monitors the changes in our biosphere and how these alterations can affect our survival. They analyze glacier movements, ozone levels, global climate and weather, and several other characteristics of our planet. Learn more about the satellites and the people that do it here.
On Mars, NASA is taking detailed soil measurements, rock compositions, and searches for life with rovers like Opportunity and Curiosity that contain enormous amounts of technology to better search for other places that might be able to sustain human—or alien—existence.
