    NASA's Europa Clipper Advances Planetary Science With Mars Flyby Success and Renewed Focus on Ocean Worlds

    According to NASA, one of the most significant recent planetary science developments in the United States is the continued progress on the Europa Clipper mission, which is now moving through instrument testing and readiness work after its Mars flyby check earlier this year. Scientists used that pass to verify the radar system in deep space conditions, and NASA says the data showed the instrument is ready for use when the spacecraft reaches Jupiter’s moon Europa, where the main goal is to study the ice shell and the hidden ocean beneath it. According to Science News, that mission remains central to U.S. planetary science because it targets one of the solar system’s most promising places to look for conditions that could support life. In California, researchers have also reported fresh evidence from dairy farms that bird flu may spread through the air under some conditions. According to Science Quickly, air samples from farms in California contained H five N one influenza virus in both large and small particles, and the same report says viral material was also found in milk, on milking equipment, and in wastewater. While this is not a planetary science result in the narrow sense, it reflects the kind of environmental and contamination research often tied to the broader planetary and Earth science community in the United States. Worldwide, planetary science news is also being shaped by new findings about rogue planets, which are worlds that drift through space without orbiting a star. According to Science Quickly, recent research suggests some of these objects may still form small planetary systems of their own, changing how scientists think about planet formation beyond our solar system. That idea is drawing attention because it expands the range of environments where planets may organize and evolve. Another major update comes from Mars science. According to Science News, NASA’s Mars orbiter MAVEN has now been declared dead after a long communication problem, ending a mission that helped scientists study how Mars lost much of its atmosphere. In the United States, that loss matters because it affects future planning for Mars missions and strengthens the case for studying atmospheric escape on both Mars and Earth. Taken together, the recent pattern in planetary science is clear. U.S. research is still anchored by flagship missions to Europa and Mars, while new discoveries about rogue planets and atmospheric loss are widening the field’s focus from individual worlds to the processes that shape entire planetary systems.

    New Wave of Data Reveals How Planets Form, Evolve, and Support Life Across the Solar System and Beyond

    Planetary scientists in the United States and around the world are using a wave of new data to probe how planets form, evolve, and potentially host life. NASA reports that analysis of the March 2025 Mars flyby by the Europa Clipper spacecraft was recently completed, confirming that its Radar for Europa Assessment and Sounding instrument, called Reason, is ready to begin mapping the hidden ice shell and possible ocean of Jupiter’s moon Europa when the spacecraft reaches the outer solar system later this decade. According to NASA Science, this successful test is a key step in a broader United States effort to understand which icy worlds might be habitable. Across the planetary science community, US based researchers are increasingly comparing our solar system with distant exoplanet systems. Phys dot org reports that astronomers have obtained a first direct view of a planet forming disk spinning around the young star AB Aurigae, revealing spirals of gas and dust that hint at giant planets taking shape. Space dot com notes that teams using ground based telescopes and space observatories are also identifying some of the longest period young transiting exoplanets yet, providing rare cases where scientists can watch wide orbit planets as they complete slow circuits around their stars. Back in the inner solar system, United States Geological Survey scientists at the Astrogeology Science Center in Flagstaff, Arizona, describe how new high resolution lunar and Martian maps are feeding into NASA’s Artemis program and future Mars exploration, especially for landing site selection near the lunar south pole where permanently shadowed craters may trap ancient water ice. At the same time, Sci News reports that a meteorite found in Africa preserves chemical signatures of a long lost massive protoplanet that once orbited in the inner solar system, giving geochemists a direct sample of the building blocks that formed Earth and its neighbors. Planetary scientists also see emerging patterns that link small scale and large scale processes. According to Science News, new work on planetary atmospheres and rogue planets is challenging earlier assumptions, suggesting that even isolated worlds drifting between stars may retain heat and, in some cases, develop miniature planetary systems of their own. Together, these developments highlight a moment when United States led missions, detailed laboratory analyses, and international astronomical surveys are converging, turning the solar system and the galaxy beyond into a comparative laboratory for understanding how planets are born, how they change, and where conditions for life might arise.

    NASA's Psyche and Europa Clipper Missions Use Mars Flybys to Navigate Outer Solar System

    In planetary science this week, attention in the United States is focused on a series of missions using close planetary flybys to fine tune their paths into the outer solar system. NASA reports that its Psyche spacecraft completed a close approach to Mars on May fifteenth, passing about two thousand eight hundred and sixty four miles above the surface. This gravity assist over the dayside of Mars slightly bent Psyche’s trajectory and set it on course for its rendezvous with the metal rich asteroid Psyche in the main asteroid belt in twenty twenty nine. Engineers at the Jet Propulsion Laboratory are analyzing changes in the spacecraft’s velocity and using images and measurements taken during the flyby to refine navigation models for deep space missions. At the same time, NASA’s Europa Clipper mission team has announced that a key instrument test during a March first flyby of Mars was successful. According to NASA Science, the Radar for Europa Assessment and Sounding instrument, which will probe the ice shell of Jupiters moon Europa, transmitted and received radio waves for about forty minutes while the spacecraft passed the planet, returning roughly sixty gigabytes of data. The analysis, completed this month, shows that the radar performed as designed in the challenging environment of deep space, clearing a major hurdle before Europa Clipper arrives at Jupiter in the early twenty thirties to search for signs of a habitable ocean beneath the ice. Beyond Mars, planetary scientists in the United States and Europe are tracking how the solar system responds to intense space weather. Phys dot org reports that observations of Mars during a recent solar storm revealed a phenomenon called the Zwan Wolf effect in the planet’s upper atmosphere, as charged particles from the Sun interacted with atmospheric gases. These measurements are helping researchers understand how Mars lost much of its original atmosphere and how future human explorers around Mars and the Moon might be affected by extreme solar events. Across these stories, a pattern is emerging. United States led missions are increasingly using planetary flybys as both navigational tools and scientific opportunities, turning brief encounters with Mars and other worlds into test beds for instruments that will later investigate icy moons and asteroids. At the same time, coordinated monitoring of solar storms across multiple planets is revealing how space weather shapes atmospheres throughout the inner solar system, linking planetary science to the practical challenge of protecting spacecraft and future astronauts.
