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.
