The Moon, gateway for science and exploration

The Moon is the only world besides Earth ever walked on by humans. By studying it, scientists can learn about Earth’s past and better understand worlds throughout the galaxy.

Venus, Earth's twin sister

Venus may have had oceans and been habitable to life before being transformed into an inhospitable wasteland.

The Sun, our Solar System’s star

We study the Sun to learn about how stars work, and to help protect our civilization from solar storms.

VIPER, NASA’s Moon resource mapper

NASA is launching the Volatiles Investigating Polar Exploration Rover, or VIPER, in 2025 to map water on the Moon’s south pole.

CLPS: NASA's commercial Moon landing missions

NASA is funding a fleet of commercial robotic Moon missions as part of the agency's Artemis program.

MMX, Japan’s Martian Moons eXploration mission

MMX launches in 2026 to study Mars' moons and return samples from Phobos to Earth in 2031.

VERITAS, NASA’s Venus mapper

NASA will launch the VERITAS spacecraft no earlier than 2031 to study Venus and its past.

Saturn, planet of rings, moons and more to explore

Saturn is the crown jewel of our solar system. It has a stunning set of rings, diverse moons, and so much more to explore.

Asteroids, comets, and other small worlds

These leftover planet-building materials are time capsules that give us a peek into our origins.

Lunar Trailblazer, NASA’s Moon water mapper

Advancing our understanding of water across the Moon for exploration and science.

MAVEN, studying how Mars lost its atmosphere

NASA's Mars Atmosphere and Volatile Evolution spacecraft, MAVEN, studies how Mars loses its atmosphere to space. The orbiter also relays communications between surface missions and Earth.

Mars Pathfinder, the start of modern Mars exploration

The Pathfinder mission deployed the first-ever wheeled rover on Mars, and technologies developed for it paved the way for future, more sophisticated exploration of the red planet.

ExoMars Rosalind Franklin rover

The European Space Agency's Rosalind Franklin rover will search for signs of life on Mars.

TESS, finding new worlds

TESS, or the Transiting Exoplanet Survey Satellites, is a U.S. mission to discover Earth-size worlds around nearby stars.
