Johns Hopkins Applied Physics Laboratory Civil Space
We Lead Missions To Defend Earth
APL leads the Double Asteroid Redirection Test — the world’s first full-scale planetary defense test mission to demonstrate one method to deflect an asteroid.
From The Sun to Pluto and Beyond
Our spacecraft and instruments have helped "touch" the Sun, measure and track Earth’s magnetosphere, search for ancient water on Mars, probe the mysteries of Pluto and measure the boundaries of our solar system before entering interstellar space. And those discoveries are just the beginning.
More APL Missions
We are scientists, engineers, planners and dedicated professionals committed to exploring space and expanding humanity’s knowledge of the Sun-Earth system, our moon, the solar system and beyond. We do the impossible every day. Learn more about the people of APL Civil Space.
