Perseverance becomes the farthest-driving vehicle on another world
NASA's Perseverance rover has passed Opportunity's long-standing record of about 28 miles driven on Mars. Thanks largely to its self-driving navigation, it did it in roughly five and a half years instead of nearly fifteen. It is now studying some of the oldest rocks in the solar system for signs of ancient habitable environments.

Astronaut hearts look ready for a trip to Mars
Researchers who followed 13 astronauts found their hearts adapted well to months of weightlessness and coped with simulated Martian gravity without major trouble. Regular exercise in orbit seemed to make a real difference, which is encouraging news for future crewed missions to the Red Planet.

A low-energy way to turn old Plexiglas into brand-new material
Chemists at ETH Zurich have found a practical method that breaks acrylic glass, the stuff in taillights, windows and sneeze guards, almost completely back into its original building blocks. That makes high-quality recycling affordable for the first time, so old acrylic could become new acrylic instead of landfill.

Detective work redates a famous solar-storm train delay to 1848
A well-known historical story of a train held up by a solar storm turns out to be off by seven years: researchers showed it happened in 1848, not 1841. Fixing the date reshapes the early history of space weather, a field that still matters because big solar storms can disrupt power grids and satellites today.
