Earth Action

NASA is an exploration agency, and one of our missions is to know our home. We develop novel tools and techniques for understanding how our planet works -- for the benefit of humanity and for insights we need to explore other moons and planets. NASA's Earth Science Division operates more than 20 satellites in orbit, sponsors hundreds of research programs and studies, and funds opportunities to put data to use for societal needs. We develop new ways to observe the oceans, land cover, ice, atmosphere, and life, and we measure how changes in one drive changes in others over the short and long term. While listening to and collaborating with industry leaders, international partners, academic institutions, and other users of our data, we drive innovations and deliver science to help inform decisions that benefit the nation and the world.

Sensing the Seas

For more than forty years, NASA has found unique ways to study the surface layers of the ocean from the tropics to the poles. With three new missions since 2020 – PACE, SWOT, and Sentinel 6-Michael Freilich – we are now ushering in a new era of ocean studies.
