Featured Missions
Our mission milestones showcase the breadth and depth of NASA science.
TRACERS
TRACERS will study magnetic reconnection—when solar activity disrupts Earth’s magnetic field—to help scientists better understand and prepare for the effects of space weather.
Lucy
The Lucy mission captured stunning, detailed images of asteroid Donaldjohanson during a fly by on April 20, 2025, as the spacecraft heads towards the distant Trojan asteroids.
NEO Surveyor
NEO Surveyor is expected to launch no earlier than September 2027. It is the first space telescope specifically designed to hunt asteroids and comets that may be potential hazards to Earth.
Registration Opens for 2025 NASA International Space Apps Challenge
NASA invites innovators of all ages to register for the NASA Space Apps Challenge, held on Oct. 4-5. The 2025 theme is Learn, Launch, Lead, and participants will work alongside a vibrant community of scientists, technologists, and storytellers at more than 450 events worldwide. Participants can expect to learn skills to succeed in STEM fields, launch ideas that transform NASA’s open data into actionable tools, and lead their communities in driving technological innovation.

How we Look at Earth
Welcome to the universe
Discover the universe: Learn about the history of the cosmos, what it’s made of, and so much more.
Astrophysics Data
Free and open access to archives of science data from both space and ground-based telescopes.
The Future of Exploration
The Nancy Grace Roman Space Telescope will investigate dark matter, dark energy, exoplanets and other mysteries of the universe.
Are We Alone?
By studying exoplanets we can compare our planet to thousands more, and find out if there are other habitable worlds in the galaxy.
Nicky Notes
To the NASA Science Community – As the nation’s leader in Earth and space science, NASA Science operates within the broader context of the federal government and its priorities. As part of the Executive Branch, we are always responsive to the direction set by the Administration, including executive orders and policy guidance that relate to our programs and activities.
