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.
Experience the closest thing to standing next to the actual JWST
Joining other historic NASA missions like Apollo, Voyager, and the Discovery Space Shuttle, Webb’s Optical Telescope Element Pathfinder has made its way to the Steven F. Udvar-Hazy Smithsonian museum for permanent display.
The Pathfinder is the largest intact mirror support structure of its kind, comprised of exotic lightweight materials invented for the purpose of seeing near to the very limits of the observable universe.
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.
Pandora
Pandora is a small satellite designed to characterize exoplanet atmospheres and their host stars. It is slated to observe at least 20 different planets during its one year of science operations.
Dragonfly
Dragonfly, the first-of-its-kind rotorcraft to explore another world, will fly to various locations on Saturn’s moon Titan and investigate the moon’s habitability.
What’s Up: April 2026 Skywatching Tips
Mercury shines at its brightest for the year, the Lyrid meteor shower peaks, and a bright new comet makes an appearance in April’s night sky. Catch Mercury low in the eastern sky before sunrise on April 3 at its greatest elongation. Then look up late April 21 into the 22nd for the Lyrids, with “shooting stars” radiating near the bright star Vega. Also this month, Comet C/2025 R3 (Pan-STARRS) may be visible with binoculars or a telescope, especially around April 17, before making its closest approach to Earth on April 27.

‘Project Hail Mary’
In the science-fiction novel and movie “Project Hail Mary,” the story revolves around the rigors of an astronaut working and surviving during a yearslong mission, the power of deep-space communications, the search for life beyond Earth, and nearby star systems that actually exist — Tau Ceti and 40 Eridani A.

Division Highlight: Heliophysics
The Science Mission Directorate Heliophysics Division studies the nature of the Sun and how it influences the very nature of space and the planets and the technology that exists there. Space is not completely empty: We live in the extended atmosphere of an active star. Our Sun sends out a steady outpouring of particles and energy known as the solar wind, carrying the Sun’s writhing magnetic field. This extensive, dynamic solar atmosphere surrounds the Sun, Earth, the planets, and extends far out into the solar system.
