Have you ever wondered were the rovers we send to Mars are built, or where spacecraft that explore the cosmos return their data to Earth? In a typical year, over 30,000 people visit NASA’s Jet Propulsion Laboratory in-person; now, you can see the Southern California facility from anywhere in the world on a virtual tour.

Focus Areas

A leader in robotic space exploration, JPL has sent rovers to Mars, probes to our solar system’s farthest reaches, telescopes into space to study the universe, and satellites into Earth orbit to better understand our home planet.

Earth Science

Studying Earth from land, air, sea, and space to better understand and manage our dynamic planet.

Solar System

Creating robotic explorers throughout our solar system to study the complex processes that have shaped the worlds within it and whether life exists elsewhere.

Asteroids and Comets

Pinpointing the paths of comets and asteroids that may pass close to Earth.


Exploring the deepest reaches of the universe to understand the forces that shape it and to search for new worlds beyond our solar system.


Developing technology to further our exploration of the universe and improve life on Earth.

Active Missions

Missions and instruments built or managed by JPL for NASA have visited every planet in our solar system as well as the Sun. While some provide key science data about our home planet, others have peered into the universe to locate planets around other stars.

Current missions that JPL has led or partnered on, such as GRACE-FO, the Curiosity and Perseverance Mars rovers, and the Ingenuity Mars helicopter continue the national laboratory’s long tradition, of being on the leading edge of robotic space exploration.
