EUROPA CLIPPER

Launched on Oct. 14, 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.

More about Europa Clipper


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.

More about Lunar Trailblazer


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.

NASA SCIENCE IS DELIVERING



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.

Read Nicky Notes
Dr. Nicola (Nicky) Fox, the Associate Administrator (AA) for the Science Mission
Directorate (SMD) for NASA, visited the University of Delaware to discuss the
scientific missions being undertaken by the SMD and to visit with various groups
on campus. Pictured: Dr. Fox visiting with Associate Professor of Physics &
Astronomy Ben Maruca and students in the Delaware Space Observation Center
(DSpOC).

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.

LUNAR DISCOVERY AND EXPLORATION

NASA scientists are focused on studying Earth’s Moon, which holds keys that will
unlock a deeper understanding of our planet, solar system, and the origins of
life.

WHAT'S OUT THERE?





PLANETARY PROCESSES

We’re studying geological processes that have been occurring on the Moon since
its inception.




VOLATILE CYCLES

We have much to learn about the elements and chemicals that make up our Moon.




IMPACT HISTORY

The impact history of the Earth-Moon system provides a historical record of our
entire solar system.




RECORD OF THE ANCIENT SUN

We can learn about the Sun by studying its effects on the Moon.




BIOLOGICAL SYSTEMS ON THE MOON

We’re studying the extreme lunar environment to determine its effects on
biological systems.




PHYSICAL SCIENCES ON THE MOON

The unique gravity properties of the Moon will inform efforts to study and
inhabit its environment.




PLATFORM TO THE SOLAR SYSTEM

The Moon provides scientists with a platform for studying the entire solar
system.

EXPLORE OUR CHANGING PLANET

Earth is our home, shared with millions of species. Rapid changes like rising
temperatures and more frequent extreme weather are transforming our planet. For
over 50 years, observations from space and ground have monitored these changes,
guiding critical decisions in areas like agriculture and air quality. By
understanding how our actions affect Earth's systems, we can help mitigate these
impacts. Discover more about how you can make a difference in safeguarding our
planet.
