Johns Hopkins Applied Physics Laboratory

The Johns Hopkins University Applied Physics Laboratory (APL) is a premier, not-for-profit research institution located in Laurel, Maryland. Established in 1942, APL operates as a university-affiliated research center (UARC) under the auspices of Johns Hopkins University.

With a dedicated workforce of approximately 8,700 employees, APL stands as the nation's largest UARC. It serves as a pivotal technical resource for the Department of Defense, NASA, and various other government agencies.

Mission and Expertise

APL's mission is to address complex research, engineering, and analytical challenges critical to national security and space exploration.

The laboratory's expertise spans a diverse array of domains, including:

• Air and missile defense
• Undersea warfare
• Computer security
• Space science

Notably, APL has been instrumental in developing and operating numerous spacecraft, such as the Transit navigation system, Geosat, ACE, TIMED, CONTOUR, MESSENGER, Van Allen Probes, New Horizons, Parker Solar Probe, and STEREO.

In 2019, APL's proposed Dragonfly mission was selected as the fourth NASA New Frontiers mission, aiming to explore Saturn's moon Titan.

Biomedical Engineering Achievements

In addition to its space endeavors, APL has made significant strides in biomedical engineering.

In 2014, the laboratory achieved a milestone by successfully using the Modular Prosthetic Limb—a fully artificial articulated arm and hand—by a bilateral shoulder-level amputee. This advancement utilized pattern recognition algorithms to enable the prosthetic to move in conjunction with the amputee's muscle contractions.

Building on this success, APL has developed one of the world's smallest and most efficient wearable thermoelectric coolers, which won an R&D 100 award in 2023.

Facilities and Locations

APL's facilities foster innovation and collaboration. The laboratory boasts a range of specialized labs and test facilities, including:

• The Intelligent Systems Center, which advances artificial intelligence, robotics, and neuroscience
• The Environmental Test Facility, conducting rigorous flight hardware testing
• The Planetary Impact Lab, studying impact cratering processes in the solar system

The laboratory's main campus spans 461 acres in Laurel, Maryland, housing over 30 buildings dedicated to various research and development activities.

APL also maintains an auxiliary campus in Columbia, Maryland, featuring the Kossiakoff Center and Montpelier 7 (MP7). These facilities support educational programs, including the Johns Hopkins Engineering for Professionals program, offering courses in engineering and applied sciences.
