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.
