On its record-breaking pass by the Sun in December 2024, NASA’s Parker Solar Probe, designed and operated for NASA by Johns Hopkins APL, captured the closest images ever taken of the Sun’s atmosphere.

Taken from just 3.8 million miles away using Parker Solar Probe’s Wide-Field Imager for Solar Probe (WISPR) instrument, the new views help scientists pinpoint how solar storms can impact Earth’s tech, from satellites to power grids, and how they form and spread.

🎥: This video, made from images taken by the WISPR instrument during its record-breaking flyby of the Sun on Dec. 25, 2024, shows the solar wind racing out from the Sun’s outer atmosphere, the corona. (@NASA/Johns Hopkins APL/@usnrl)

A team of robots navigates through the rubble-strewn scene of a remote natural disaster, looking for survivors. From a distance, another team provides situational awareness, alerting the first team to evolving hazards. As the search continues, the two teams dynamically swap roles to keep up with the emerging situation, with one team serving as lookout while the other carries out the rescue mission.

Like many scenarios once considered pure science fiction, this disaster response use case is plausible for multirobot teams in the not-too-distant future. However, implementing it in the real world presents some thorny technical problems.

Researchers at Johns Hopkins APL have made significant progress toward addressing some of the fundamental challenges that stand in the way of the vision becoming reality. Find out how in the #LinkInBio 🔗

How do microcapsules work?

At Johns Hopkins APL, researchers are advancing encapsulation techniques that precisely control when and where chemical reactions occur. The work could enable innovative materials and processes for national security applications, from underwater adhesives to secure manufacturing technologies.

Researchers are also using the AI-enabled Microcapsule ATLAS project to accelerate microcapsule development, reducing hands-on researcher time from nine hours per experiment to less than 90 minutes.

Inspired by the Apollo era, Sam Yee and Scott Murchie turned early curiosity about space into careers that helped shape understanding of Earth, Mars and the broader solar system.

These two APL scientists recently received APL’s Lifetime Publication Achievement Award, recognizing decades of high-impact research and more than 450 scientific papers. Their work demonstrates how publishing advances discovery, informs future missions and strengthens the scientific community.

“I’m incredibly grateful for this award,” Murchie said. “Publications are how our work reaches the community, so this honor reflects many years of collaboration and team efforts.”

More than 600 attendees representing the @USNavy submarine force, allied nations, industry, and academia gathered at APL May 5-7 for the 38th annual Submarine Technology Symposium.

Hosted by Commander, Submarine Forces, and co-sponsored by the Naval Submarine League and APL, the symposium focused on the theme “Forged to Fight – Global Reach from the Undersea” and examined how undersea forces can maintain their advantage in an increasingly contested maritime environment.

NASA’s Dragonfly mission is taking shape.

Johns Hopkins APL recently completed structural testing of the rotorcraft lander’s frame assembly, a major milestone that clears the way for the next phase of spacecraft integration. Engineers will now begin installing the electronics, avionics, instruments, and other flight hardware that will transform Dragonfly into the flying science lab designed to explore Saturn’s moon Titan.

📸 2: Suspended by four bungee cords, the Dragonfly structure is positioned inches above the floor during ground vibration tests in one of APL’s clean rooms. These tests give engineers the opportunity to see how vibrations in Dragonfly’s rotors may resonate across the lander’s main body, potentially interfering with other equipment.

📸 3: Engineers mount the inverted Dragonfly structure to a vibration table at APL’s vibration test facility. Vibration tests expose the lander structure to a systematic series of tests that ensure it can hold up to the forces it will experience during launch, entry into Titan’s atmosphere, and landing on the surface of this ocean world.

One of the largest sporting events in U.S. history includes millions of fans and dozens of matches.

But behind the scenes, Johns Hopkins APL’s Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE) biosurveillance system is helping public health officials monitor emerging threats throughout the tournament.

By bringing together data from multiple sources, ESSENCE helps users identify unusual patterns, track disease trends, and improve awareness during major events.

For more than two decades, the system has helped agencies respond to emerging public health threats. Today, the ESSENCE team continues to advance the platform through new analytics, workflow improvements, and AI-enabled capabilities designed to help users uncover critical insights more quickly.
