Message from the Sciences and Exploration Director
Dr. Colleen Hartman

I'd like to welcome you to NASA Goddard's Science and Exploration Directorate -- the largest Earth and space science research organization in the world. Located across our main campus at Greenbelt, MD, New York City and Wallops Flight Facility, we total more than 2,000 employees, including civil servants, university scientists, contractors and students.

We like to say Goddard begins with science. With an interwoven and collaborative team of world-class scientists, engineers and technologists, we take ideas from concept to launch and discovery. We are trailblazers, on Earth and in space, with an official mission to explore fundamental questions about our Earth, our sun, the planets and the universe. We seek to better understand our universe and the relationship between our physical world and human life.

Goddard scientists collect and model data from space, air, land and sea. Goddard's Sciences and Exploration Directorate is comprised of four main areas of scientific study: Earth Sciences, Astrophysics, Heliophysics and Solar System Exploration. Housing these distinct, but interconnected, science disciplines under one roof gives us cross-disciplinary insights and capabilities. For example, I'm thrilled to support multi-disciplinary research such as the Sellers Exoplanet Environments Collaboration (SEEC), which promotes the cross-fertilization of research between the Earth and space science fields. It is this kind of collaborative endeavor that will uncover new horizons in scientific exploration.

Please take some time to explore our Web pages, including each division, for a wealth of information on our work in NASA Science. We love what we do, and hope you will be inspired, as well.
