For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge, and making research breakthroughs that are not possible on Earth.

Why go to space?

Human space exploration addresses fundamental questions about our place in the universe and the history of our solar system. NASA’s exploration vision is anchored in providing value for humanity by answering some of the most fundamental questions: Why are we here? How did it all begin? Are we alone? What comes next?

Where are we going?

Never has humanity endeavored to simultaneously architect multinational infrastructures in lunar orbit, on the lunar surface, and at Mars — all while maintaining high-demand government and private-sector operations in low Earth orbit. Learn more about NASA's destinations for human exploration.

Living in Space

From the challenges of providing optimal nutrition to managing the risks posed by microgravity, NASA works to predict, assess, and solve the problems that humans encounter in space. Take a look at resources related to life in space.

Commercial Space

NASA supports a robust commercial space economy that advances American industry and promotes technological discovery through in-space work and research. American companies will continue to play an essential role in establishing a sustainable presence in space.

Artemis Missions to the Moon and Mars

Under the Artemis campaign, NASA will establish long-term lunar exploration for scientific discovery and preparing for human missions to Mars.

Astronauts

Astronauts train for a variety of missions, including performing research on the International Space Station, launching from American soil on spacecraft built by commercial companies, and preparing for missions to the Moon with Artemis.
