- BepiColombo nears Mercury after eight-year journey — European Space Agency
The ESA/JAXA mission will arrive at the innermost planet following a series of gravity assists that stretched the cruise phase. Two orbiters will separate upon arrival to study the planet’s surface, exosphere, and magnetic field from complementary vantage points. A new media kit outlines the final approach timeline and the instruments each spacecraft carries. Scientists expect the dual-spacecraft configuration to resolve long-standing questions about how Mercury’s unusually strong magnetic field is generated. The mission’s arrival media kit details every remaining milestone from the final flybys through orbital insertion and the start of routine science operations. Watch for the first science data releases once the orbiters settle into their operational paths.

- Meteorite dust preserves record of early solar nebula magnetism — Phys.org
Researchers examined tiny metallic grains inside primitive meteorites to reconstruct magnetic fields present when the Sun and planets were forming. The measurements show that magnetic fields in the inner solar nebula were strong enough to influence how dust clumped into larger bodies. The work provides direct evidence of conditions that existed roughly 4.6 billion years ago. The study focuses on grains that recorded field orientations before they were locked into parent asteroids. Follow-up studies will compare grains from different meteorite classes to map how those fields varied with distance from the young Sun.
- Perseverance images Phobos transit across the Sun — Sci.News
NASA’s Perseverance rover captured a silhouette of the Martian moon Phobos passing in front of the solar disk. The event lasted only seconds from the rover’s viewpoint on the surface. Such transits help refine orbital models of Phobos and demonstrate the rover’s camera timing precision. The images add to a growing record of Phobos transits observed by surface assets. Scientists plan to use similar observations to monitor changes in the moon’s orbit over time.

BepiColombo’s arrival marks the first time two spacecraft will orbit Mercury simultaneously. One will map the surface and magnetic field at low altitude while the other studies the planet’s thin exosphere from a higher vantage. The dual perspective should finally clarify why Mercury’s magnetic field is so much stronger than models predicted for its size. The mission’s success also demonstrates how gravity-assist tours can deliver complex payloads to difficult destinations without larger rockets. What will the first simultaneous magnetic-field measurements reveal about the planet’s molten core?
Picture a cloud of gas and dust once spanning roughly 100 times the distance from the Sun to Neptune; if that entire structure were scaled down to the size of a football stadium, the region where Earth eventually formed would occupy only the space of a single blade of grass. Inside that vast but diffuse disk, tiny metallic grains began aligning with invisible magnetic field lines like compass needles caught in wet cement. As the grains were later incorporated into asteroids and then broken apart into meteorites, those alignments froze in place, preserving a snapshot of field strength from more than four billion years ago. Laboratory instruments can now read the orientation of those grains to within a few microtesla, revealing that the inner nebula’s magnetism was strong enough to help dust overcome turbulence and clump together. Yet we still cannot explain why the field strength appears to drop so sharply beyond the present-day asteroid belt, a pattern that shows up consistently across multiple meteorite families. Solving that gradient would tell us whether magnetic fields or some other process set the boundary between the rocky and icy worlds we see today.
Space keeps delivering new chapters; the trick is noticing which ones change the story.
