NASA Science
NASA Science seeks to discover the secrets of the universe, search for life elsewhere, and protect and improve life on Earth and in space.
Featured Missions
Our mission milestones showcase the breadth and depth of NASA science.
IMAP
Launched September 24, 2025, IMAP will help researchers better understand the boundary of the heliosphere, a huge bubble created by the Sun surrounding and protecting our solar system.
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.

Citizen Science
Join NASA researchers and discover the secrets of the universe, search for life elsewhere, and protect and improve life on Earth and in space.
Through these projects, sometimes called “citizen science” or “participatory science” projects, volunteers and amateurs have helped make thousands of important scientific discoveries. These projects are open to everyone (no citizenship required).
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.
