NASA has defined a set of space and Earth Science questions that can best be addressed using the Agency’s unique capabilities. NASA works with the broader scientific community, considers national initiatives, and the results of decade-long surveys by the National Research Council in defining these questions.
See also the Science Strategy section for more information about how NASA Science is pursuing these questions.
- How do matter, energy, space, and time behave under the extraordinarily diverse conditions of the cosmos?
- How did the universe originate and evolve to produce the galaxies, stars, and planets we see today?
- What are the characteristics of planetary systems orbiting other stars, and do they harbor life?
