A new Johns Hopkins APL-led study using NASA's James Webb Telescope suggests carbon dioxide and similar molecules on Uranus’ moon Ariel may be emerging from the inside, raising questions about the moon’s geologic activity and potential as an ocean world. 🌊 https://jhuapl.link/sm8 This fact presents a surprise because even at the frigid reaches of the Uranian system, 20 times farther from the Sun than Earth, carbon dioxide readily turns to gas and is lost to space. Some scientists favor the idea that interactions between the moon’s surface and charged particles in Uranus' magnetosphere create carbon dioxide through a process called radiolysis, in which molecules are broken down by ionizing radiation. A research team led by APL's Richard Cartwright found that Ariel has some of the most carbon dioxide-rich deposits in the solar system. Among those deposits was another puzzling finding: the first clear signals of carbon monoxide. The new spectral observations hint that Ariel’s surface may also harbor carbonate minerals — salts that can be made only through the interaction of liquid water with rocks. Cartwright sees that as an opportunity to collect valuable data about the solar system’s ice giants and their potentially ocean-bearing moons, both of which have applications to the worlds being discovered in other stellar systems. #JHUAPL | #SpaceResearch | #PlanetaryScience | #OceanWorld | #Geology | #JamesWebbSpaceTelescope | NASA - National Aeronautics and Space Administration

John's Hopkins APL computational physicist and aerospace engineer Paul Burke will join some of the country’s most promising early-career engineers to discuss pioneering research and technical advancements at the National Academy of Engineering's National Academies Frontiers of Engineering Symposium. 🚀 https://jhuapl.link/ip1 The symposium will explore topics such as digital twin technology, human health and artificial intelligence, advanced materials and the future of computing. One of Burke’s projects is the development of an aortic digital twin. Collaborating with researchers from the The Johns Hopkins University School of Medicine, he is studying blood flow and aortic shape in pediatric patients with connective tissue disorders. Burke is also working on computational models to optimize the use of resources on the lunar surface, essential for long-term human and robotic exploration on the Moon. #JHUAPL | #EngineeringInnovation | #FrontiersOfEngineering | #AIinHealthcare | #LunarExploration

#NationalMoonDay On this day in 1969, humans landed on the moon for the first time. Fifty-four years later, the Moon is a cornerstone of solar system science and the closest world beyond our own on which humans may establish a sustainable presence. 🌒 Today, easier access to space has opened new possibilities for government and commercial organizations to use cislunar space and the lunar surface for a variety of purposes. This has driven the need for additional capabilities to enhance safety and security for operating in cislunar space.

Space Weather affects all of us. ☀️ Behind the beauty and wonder of our Sun lies powerful forces to create giant eruptions - such as solar flares and coronal mass ejections - that blast energy, light, and particles into space, creating so-called geospace storms. These storms can impact infrastructure in near-Earth orbit and on Earth’s surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations, while triggering spectacular displays of aurora on Earth. This video represents a hypothetical scenario for a space weather event.

If the Climate TRACE dataset someday included non-GHG pollutants, how would you use the data? Air pollution has major implications for human health. The World Health Organization estimates that 6.7 million premature deaths are caused by air pollution globally each year. Access to granular, timely, and accurate pollution data could unlock new solutions for public health. Thanks to support from Clean Air Fund and an initial scoping study with Climate TRACE member The Johns Hopkins University Applied Physics Laboratory, we’re exploring how we could fill the gaps in non-GHG pollution datasets. https://lnkd.in/dn4VCrY2 #CleanAirFund #AirPollution #ParticulateMatter #PollutionData

Johns Hopkins APL researchers are accelerating multi-principal element alloy (MPEA) design by developing complex, high-strength microstructures that provide composition information from only a few samples. The researchers developed a design capability to synthesize 17 unique MPEA compositions and present characterization data on over 7,000 unique data points. https://jhuapl.link/u8g To predict which MPEA compositions to manufacture, APL partnered with Paulette Clancy and Maitreyee Sharma Priyadarshini at the Johns Hopkins Whiting School of Engineering. With limited data, they used their physics-informed Bayesian optimization algorithm, PAL 2.0, to quickly sift through alloy possibilities and recommend MPEAs that maximize hardness and provide the widest sample of data for future development. After Clancy’s group provides recommendations on which alloys to test, the APL team creates the alloys and conducts arc melting, which sends an electronic current through the metal to melt it. Arc melting can be achieved with minimal material, making it a quick way to sample vastly different compositions. The technique is one of many APL is developing and testing to speed up materials discovery and understanding. #JHUAPL | #MaterialsScience | #AdvancedManufacturing | #EngineeringInnovation | #AIinScience | #MachineLearning

Johns Hopkins APL Director Ralph D. Semmel has announced that he will step down from his role in July 2025, marking the conclusion of 15 remarkable years leading the nation’s largest university affiliated research center. https://jhuapl.link/lf0 “Serving alongside APL’s dedicated staff members has been the greatest professional honor of my life,” said Semmel. “My colleagues have made amazing contributions to many of the most daunting challenges facing our nation, and taken what was already a remarkable organization to incredible new heights. That is what every APL director strives and hopes for during their tenure, and I could not be prouder of all we have achieved.”

NASA released a summary of the fifth iteration of a Planetary Defense U.S. Government Interagency Tabletop Exercise held at Johns Hopkins APL, which brought together domestic and international leaders to evaluate a global response to a simulated asteroid impact threat to Earth. https://jhuapl.link/iy3 Representatives from NASA, the Federal Emergency Management Agency (FEMA), the European Space Agency (ESA), the United Nations and other domestic and international agencies were among the participants. Although no known significant asteroid impact threats exist in the foreseeable future, the exercise walked participants through a hypothetical scenario in which astronomers discover an asteroid with a significant chance of impacting Earth 14 years in the future. The situation required officials to discuss, coordinate and agree on courses of action, including timelines for potential space missions to gather more information about the asteroid and to possibly prevent its impact. Organizers plan to publicly release an after-action report for the tabletop exercise, detailing strengths and outstanding gaps for which future investments can be targeted. The report will also provide recommendations for future planetary defense exercises. #JHUAPL | #PlanetaryDefense | #AsteroidImpact | #SpaceSafety | NASA - National Aeronautics and Space Administration | FEMA | European Space Agency - ESA
