From the distant reaches of the Universe, to black holes, and the Martian surface, NASA explores some of the most far out parts of space. But NASA also does research much closer to home. In fact, NASA Earth Science satellites are taking part in the management and recovery of an ecosystem right in our backyard, the Chesapeake Bay.
By studying the landscape around the Chesapeake Bay, NASA spacecraft are helping land managers figure out how to battle the harmful pollutants that have added to the destruction of the bay's once legendary productivity.
