APL’s Response to COVID-19 Laboratory Operations and Visitor Guidance

APL Campus

The Johns Hopkins University
Applied Physics Laboratory

We solve complex research, engineering, and analytical problems that present critical challenges to our nation. APL—the nation’s largest university affiliated research center—provides U.S. government agencies with deep expertise in specialized fields to support national priorities and technology development programs. We also serve as independent trusted technical agents to the government, providing continuity for highly complex, multigenerational technology development systems.

Our Purpose

Our Purpose

Our purpose is to make critical contributions to critical challenges. At APL, we feel it is our responsibility to try to solve these national challenges with the full measure of our dedication and expertise.

Our Core

Our Values

The Lab’s core values are unquestionable integrity, trusted service to the nation, world-class expertise, and game-changing impact—all in an environment that is collaborative, fulfilling (and even fun!).

Our Future

Our Goal

APL’s purpose and core values guide our future, and it is no less than to create defining innovations that ensure our nation’s preeminence in the 21st century.

New Simulations Unravel Mystery Behind Aurora’s ‘String of Pearls’

Using novel computer models and some of the world’s largest supercomputers, researchers in the APL-led Center for Geospace Storms have unraveled a longstanding mystery of why the aurora sometimes takes the shape of beads in the sky, and whether they portend magnetic mayhem in the near future.

Simulations Show Lander Exhaust Could Cloud Studies of Lunar Ices

Renewed efforts to put humans on the Moon could eventually lead to more landers touching down on the lunar surface. But a new study led by Johns Hopkins APL scientists shows exhaust from such landers can quickly spread and potentially contaminate scientifically valuable ices near the Moon’s poles.

Parker Solar Probe Mission Turns a Terrific Two

On Aug. 12, Parker Solar Probe reaches the two-year mark in its journey to unlock the mysteries of the Sun. Celebrate the mission’s second launch anniversary with a look at the discoveries and milestones reached during Parker Solar Probe’s most recent year in space.

Danielle Chou Named AAAS Science and Technology Fellow

Danielle Chou, a project manager at the Johns Hopkins Applied Physics Laboratory in the Air and Missile Defense Sector, recently accepted a one-year AAAS Science and Technology Policy Fellowship to work with the Department of Energy's Vehicle Technologies Office in Washington, D.C.

Johns Hopkins APL Hosting Final Installment of DARPA Virtual Combat Competition

APL will virtually host the third and final installment of DARPA’s AlphaDogfight Trials (ADT) from Aug. 18 to 20. DARPA tapped APL’s expertise in software development, AI development, modeling and simulation, as well as aircraft dynamics and controls to create the simulation environment and AI for the three ADT competition events.

Iron Meteorite “Fingerprints” Reveal New Details About Planet Formation

A new study that included Johns Hopkins APL planetary scientist Nancy Chabot reveals new details about iron meteorites and the formation of planets during the solar system’s youth, but it also highlights that scientists may currently be missing a large chunk of the meteorite record from these early planetary bodies.

Predicting the Unpredictable — The Dynamics of DART’s Dive Into an Asteroid

What will happen after NASA’s DART spacecraft finally collides with its target asteroid? With myriad potential outcomes, and little known about the asteroid, the answer seems almost impossible to determine. Yet modelers from Johns Hopkins APL are slowly narrowing the range of possibilities, and providing the tools that will be needed to defend Earth from a cataclysmic impact.
