Featured Missions
Our mission milestones showcase the breadth and depth of NASA science.
TRACERS
Launched July 23, 2025, 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.
What’s Up: August 2025 Skywatching Tips from NASA
A close conjunction of Jupiter and Venus peaks on the 11th and 12th. Viewing the Perseid meteors will be hampered by a bright Moon. And look for the Dumbbell Nebula, which offers a peek into how stars like our Sun go out in style.

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
