In July 2025, the European Space Agency’s Mars Express orbiter captured a high-resolution image of Acheron Fossae, a region marked by deep chasms and ridges on Mars’s surface. These features, created by ancient crustal stretching, split the terrain into raised horsts and sunken grabens. Valley floors reveal smooth surfaces carved by slow-moving, ice-rich rock glac…

As lunar exploration surges, scientists warn that the Moon’s limited stable orbits are growing crowded. Georgia Tech simulations suggest that with about 50 satellites, each may need several collision-avoidance maneuvers per year. Even now, orbiters like Chandrayaan-2 require frequent course corrections. With Artemis and private missions incoming, agencies are develo…
