From the Sun to Earth and beyond, Johns Hopkins APL is disrupting the future of space science and exploration
Since the dawn of the Space Age, Johns Hopkins APL has pushed the frontiers of space science, engineering, and exploration. We captured the first picture of Earth from space, invented navigation by satellite, and have dispatched spacecraft across the solar system from our Sun to Pluto and beyond, and we continue to shape the future by providing our nation with innovative and low-cost solutions to its space challenges.
We have designed and built more than 70 spacecraft and hundreds of specialized instruments. Combined, these spacecraft and instruments have visited every planet in our solar system and collected information that has expanded humankind's understanding of the universe.

Set to launch in 2025, NASA’s Interstellar Mapping and Acceleration Probe (IMAP) mission will help researchers better understand what happens at the boundary of the heliosphere, where the Sun’s protective magnetic field ends. -
Double Asteroid Redirection Test (DART)
NASA’s first planetary defense mission—the APL-led Double Asteroid Redirection Test (DART)—is the first mission to demonstrate what’s known as the kinetic impactor technique, which involves striking an asteroid to shift its orbit and deflect it from Earth. -
Europa Clipper
The search for life in the solar system beyond Earth gets a boost when NASA’s Europa Clipper mission launches in the mid-2020s to explore under the icy crust of Jupiter’s moon Europa. -
New Horizons
Not even four years after NASA’s New Horizons spacecraft left Pluto and its moons in the rearview mirror—and revolutionized humankind’s view of these small, dynamic worlds on the edge of our solar system—the APL-built and -operated probe conducted a flyby of an ancient Kuiper Belt object, named Arrokoth, on New Year’s Day 2019. -
Parker Solar Probe
NASA’s Parker Solar Probe—designed and built at APL—launched in August 2018 and has already traveled closer to the Sun than any spacecraft in history. -
CubeSat Signal Preprocessor Assessment and Test (CAT)
APL has successfully established communications with two miniaturized satellites, or CubeSats, as part of a Lab-led flight demonstration known as CAT. -
Space Weather Sensors
Knowing the distribution and direction of energetic charged particles along a spacecraft’s trajectory is key to situational and satellite-health awareness, yet many missions resist flying particle sensors because the instruments can be heavy and expensive. -
Space Security and Defense
APL provides expertise to the Space Security and Defense program, a joint Department of Defense/Office of the Director of National Intelligence organization focused on creating a more resilient and enduring national security space capability. -
Spacebased Kill Assessment (SKA)
APL developed and tested the sensors for the Missile Defense Agency’s SKA system, currently on orbit and executing planned test events.
