This March, NASA's Electrojet Zeeman Image Explorer (EZIE) trio of solar-powered CubeSats will soar above Earth’s electrojets, which flow just 60 miles above the surface. Designed and built by Johns Hopkins APL, each CubeSat carries a Microwave Electrojet Magnetogram (MEM) instrument that exploits the Zeeman effect—the splitting of spectral lines from thermal radiation emitted by oxygen in the ionosphere—to map Earth’s magnetic field and electric currents, producing unprecedented 2D maps of the electrojets’ distribution across 90-300 miles from 50 miles above Earth’s surface.

Researchers at Johns Hopkins APL are developing an augmented reality (AR) system that leverages predictive anatomy visualization, artificial intelligence and real-time ultrasound to help medics provide faster and more accurate medical care in the field. https://jhuapl.link/5fa In remote conflict zones and disaster-stricken areas, hospitals are often hundreds of miles away. Medical teams must provide critical care — with limited resources and while under constant threat — to patients with wide-ranging medical needs. Using a statistical shape atlas — a detailed map of human anatomy — the system predicts the location of internal organs based on external landmarks. “These models allow medics to ‘see’ beneath the skin and predict where organs are situated,” explains Anna Knight, a biomedical engineer leading the project. Deep-learning techniques, powered by data from hundreds of CT scans, enhance these anatomical predictions, which are displayed in real time via an AR headset. While AR isn’t yet commonplace in battlefield medicine, this technology could soon revolutionize training and, eventually, empower any service member to deliver advanced care in high-stakes environments. #JHUAPL | #ArtificialIntelligence | #AugmentedReality | #MedTech | #FutureOfMedicine | #HealthcareInnovation | #TechTransfer

Meet the Electrojet Zeeman Imaging Explorer (EZIE): NASA’s mission to uncover the mysteries of Earth’s electrojets, launching this March. Designed, led and managed by Johns Hopkins APL, EZIE will use a trio of small satellites to characterize and record the magnetic structure of the auroral electrojets—high-speed, electric currents in the upper atmosphere—over space and time. This mission will fill crucial gaps in our understanding of this space weather phenomenon, its impact on Earth, and offer insights applicable to other magnetized planets, both within and beyond our solar system.

The final instrument flying on NASA’s Interstellar Mapping and Acceleration Probe (IMAP) has been integrated onto the spacecraft and is currently being tested at Johns Hopkins APL. https://jhuapl.link/67a Before IMAP embarks on its mission, the spacecraft is undergoing operations simulating launch and space environments. IMAP carries 10 instruments, including IMAP-Ultra — an energetic neutral atom imager designed and built by APL — to study the solar wind, interstellar dust and particles in space. IMAP-Ultra will also help us understand how the Sun’s heliospheric bubble protects the solar system. “Now that all the instruments have been integrated, we will focus on ensuring the spacecraft can endure the rigors of launch and life in space,” said Justin Hahn, the I&T lead for the IMAP mission. “The challenge with IMAP is the variety and number of instruments.” #JHUAPL | NASA - National Aeronautics and Space Administration | Princeton University | #IMAPMission | #SpaceExploration | #Heliophysics | #SatelliteTechnology

New research from Johns Hopkins APL suggests trench-like grooves on Uranus' moon Ariel may exchange materials between its surface and interior. https://jhuapl.link/505 The findings, published Feb. 3 in the Planetary Science Journal, describe how Ariel's trenches could be spreading centers, similar to those on Earth's seafloors, where tectonic and volcanic activities transport materials. Re-examining data from Voyager 2 — the only spacecraft to capture close-up images of Uranus' moons — the research team concluded that these features likely form as convection in Ariel’s interior transports material upward, splitting the surface and emplacing new crust. Driven by tidal forces from orbital resonances — precise alignments causing gravitational interactions that generate heat — this process may have also supported a remnant subsurface ocean on Ariel. As Uranus becomes a higher priority for exploration, Ariel and its mysterious grooves could soon be studied in greater detail, revealing new insights into the moon’s history and present state. #JHUAPL | NASA - National Aeronautics and Space Administration | American Astronomical Society (AAS) | #SpaceExploration | #PlanetaryScience | #Uranus | #Geology
