NASA Science Missions
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.
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.
Eye on Infinity: NASA Celebrates Hubble’s 35th Year in Orbit
In celebration of the Hubble Space Telescope’s 35 years in Earth orbit, NASA is releasing an assortment of compelling images recently taken by Hubble, stretching from the planet Mars to star-forming regions, and a neighboring galaxy.
