Earth Missions

CALIPSO
CALIPSO will provide the next generation of climate observations, drastically improving our ability to predict climate change and to study the air we breathe.

Learn more about Calipso on NASA's website.

Gravity Probe-B
This mission is the relativity gyroscope experiment developed by NASA and Stanford University to test two unverified predictions of Albert Einstein's general theory of relativity.

OSTM/Jason-2
Jason-2 was launched in June of 2008 to continue the important investigations of Earth's oceans, began earlier by the Jason-1 mission and the TOPEX/Posiedon mission. The information gathered by the Jason-2 mission will help scientists understand the complicated process of climate change.
