Eyes on the Earth

Chances are, most of us will never get to view Earth as Sally Ride did during her flights on the Space Shuttle Challenger. However, computer simulations like Eyes on the Earth 3-D give us the opportunity to explore Earth from the eyes-in-the-sky perspective of more than a dozen NASA satellites currently orbiting the Earth.

Take a Closer Look at AQUA or OSTM

As demonstrated in the introductory video, some of the satellite missions featured in Eyes on the Earth 3-D have associated data sets. Choose one of the following satellites with data sets (AQUA or OSTM) to explore more closely. As you go through this exercise, think about how you might use one of these data sets to teach your students about an environmental issue.
