GOES-U Launch
This 2024 Earth Day poster is an ocean themed vertical 15x30 illustration created from NASA satellite cloud imagery overlaid on ocean data. The white cloud imagery wraps around shapes, defining three whales and a school of fish. Swirly cloud patterns, called Von Kármán Vortices, create the feeling of movement in the composition. The focal point is a cyclone in the upper third of the poster. At the center flies the recently launched PACE satellite. The ocean imagery – composed of blues, aquas, and greens – is filled with subtle color changes and undulating patterns created by churning sediment, organic matter and phytoplankton.

Welcome to our NASA Science website

A gateway to our missions, research, and engagement efforts.

The Science Mission Directorate inspires the learners of today and develops the leaders of tomorrow. One of our key strategies is to purposefully and actively engage with audiences and learners of all ages to share the story of NASA’s integrated science program. From exoplanet research to better understanding Earth’s climate to understanding the influence of the sun on our planet and the solar system, our work is interdisciplinary and collaborative. Similarly, this website showcases our work in a crosscutting way so that we may build stronger connections with you, our most important stakeholder. Together, we lead a globally interconnected program of scientific discovery that encourages innovation, positively impacts people’s lives, and is a source of inspiration.

Featured Missions

Our mission milestones showcase the breadth and depth of NASA science.

Artist concept of the GOES-U satellite in orbit around the earth


Launching no earlier than May 2024, GOES-U will provide advanced detection and monitoring of environmental phenomena that directly affect public safety, protection of property, and the nation’s economic health.

Europa Clipper

Launching in October 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.

Illustration of NASA's Volatiles Investigating Polar Exploration Rover (VIPER) on the surface of the Moon


VIPER launches late 2024 and will be NASA's first robotic Moon rover to measure the location and concentration of water ice and other resources. These resources could eventually be harvested to sustain human exploration on the Moon, Mars — and beyond!

This is a Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape made up of bright blue stars wound around a yellow-white hub of central stars. The hub has a slash of stars across it, called a bar. The galaxy is tilted face-on to our view from Earth. A slightly s-shaped white line across the top is a Hubble image is of an asteroid streaking across Hubble's view. It looks dashed because the image is a combination of several exposures of the asteroid flying by like a race car.

The Sun and Heliophysics

NASA studies the star at the center of our solar system and its influence on space, Earth, and our solar system. This research helps us to not only understand how the universe works, but also protect our technology and astronauts in space.
