Featured Missions
Our mission milestones showcase the breadth and depth of NASA science.
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.
PACE
PACE is celebrating one year in orbit, tracking ocean health, air quality, and climate. Its data is helping us understand how carbon moves between the ocean and atmosphere.

Dive into the Universe about Astrophysics
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.
Explore our changing planet
Earth is our home, shared with millions of species. Rapid changes like rising temperatures and more frequent extreme weather are transforming our planet. For over 50 years, observations from space and ground have monitored these changes, guiding critical decisions in areas like agriculture and air quality. By understanding how our actions affect Earth's systems, we can help mitigate these impacts. Discover more about how you can make a difference in safeguarding our planet.
