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.

NASA's NEO Surveyor is seen in this illustration against an infrared observation of a starfield made by the agency's WISE mission.

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.

Astrophysics

Studying the universe, pushing the boundaries of what is known of the cosmos, and sharing its discoveries for all of humanity.

Dive into the Universe about Astrophysics
A concentration of bright blue stars occupies the bottom right corner of the image. At bottom center within them is a small blue bubble. The stars and bubble are part of a diffuse dwarf galaxy that extends beyond the image border. Background galaxies are scattered across the image, with some particularly prominent spirals located at upper left and upper right. The background of space is black.

Nancy Grace Roman Telescope against a purple galaxy

The Nancy Grace Roman Space Telescope will investigate dark matter, dark energy, exoplanets and other mysteries of the universe.

An M dwarf star is seen with three exoplanets.

By studying exoplanets we can compare our planet to thousands more, and find out if there are other habitable worlds in the galaxy.
