Featured Missions
Our mission milestones showcase the breadth and depth of NASA science.
Lunar Trailblazer
Launching in 2024, the goal of Lunar Trailblazer is to understand the form, abundance, and distribution of water on the Moon, and the lunar water cycle.
NISAR
Launching in 2025, NISAR will systematically map Earth and study changes to ice sheets, glaciers, and sea ice in fine detail, as climate change warms the air and ocean.
GeoXO
GeoXO will advance observations of Earth’s weather, atmosphere and ocean for short-term forecasts and warnings and long-term planning for the effects of our changing planet.
Found: First Actively Forming Galaxy as Lightweight as Young Milky Way
For the first time, NASA’s James Webb Space Telescope has detected and “weighed” a galaxy that not only existed around…

Mars Chopper Concept for Future Exploration
This short animation depicts a NASA concept for a proposed follow-on to the agency's Ingenuity Mars Helicopter called Mars Chopper, which remains in early conceptual and design stages. In addition to scouting, such a helicopter could carry science instruments to study terrain rovers can’t reach. The concept was discussed by Chopper project manager Teddy Tzanetos of NASA’s Jet Propulsion Laboratory, during a Dec. 11, 2024, briefing at the annual meeting of the American Geophysical Union in Washington.

NASA Science is delivering: every second of every day, of every week, of every year. 2024 is proving to be yet another year of exceptional scientific discovery and achievement. From soft landing back on the Moon a few months ago, to celebrating the Heliophysics Big Year and a Total Solar Eclipse in the contiguous United States, to receiving stunning imagery from James Webb, NASA Science is as busy as ever. Recently launched earth science missions are also providing us unprecedented views of our planet and incredible insight into the health of our oceans and atmosphere, and helping decision-makers improve lives on Earth and safeguard our future. And we are charting a new, sustainable path for Mars Sample Return.
Looking ahead, we have many exciting launches on the horizon. At NASA, we are fortunate that our science and exploration endeavors are inextricably linked and help us discover and innovate for the benefit of humanity. Together, we explore to advance scientific understanding. Ultimately, exploration enables science, and science enables exploration.
The NASA Science team is continuing to deliver for the benefit of all.
