Welcome to our redesigned NASA Science website
A gateway to our missions, research, and engagement efforts.
The Science Mission Directorate inspires the learners of today and develops the leaders of tomorrow. One of our key strategies is to purposefully and actively engage with audiences and learners of all ages to share the story of NASA’s integrated science program. From exoplanet research to better understanding Earth’s climate to understanding the influence of the sun on our planet and the solar system, our work is interdisciplinary and collaborative. Similarly, this new website showcases our work in a crosscutting way so that we may build stronger connections with you, our most important stakeholder. Together, we lead a globally interconnected program of scientific discovery that encourages innovation, positively impacts people’s lives, and is a source of inspiration.
