Featured Missions
Our mission milestones showcase the breadth and depth of NASA science.
Europa Clipper
Launching October 10, 2024, Europa Clipper’s main science goal is to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life.
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 2024, 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.
Teams Hold Flight Readiness Review for NASA’s Europa Clipper
NASA, SpaceX, and Europa Clipper mission managers met on Friday, Oct. 4, to conduct a Flight Readiness Review and certified its readiness to initiate final launch preparation activities. Europa Clipper’s launch period opens at 12:31 p.m. EDT Thursday, Oct. 10.

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.
By the Numbers
Science is interconnected; no important question stands alone. The Science Mission Directorate (SMD) is an organization where discoveries in one scientific discipline have a direct route to other areas of study. This flow is something extremely valuable and is rare in the scientific world.
