Johns Hopkins Applied Physics Laboratory Civil Space

We Lead Missions To Explore the Habitability of Other Worlds
APL leads Dragonfly — a game-changing rotorcraft to study the surface and organic chemistry of Saturn's largest moon, Titan.
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.
