4+ hour, 21+ min ago   (707+ words) Observing comets is tricky. They're easier to see when they're closer to the Sun, but proximity to the star heats them up and releases volatiles. That creates a coma around the comet, which shrouds its nucleus, hiding it from studious…...

19+ hour, 21+ min ago   (408+ words) ~ Extremadura Libre ~ Originally published 11 April 2026 Artemis II traverses space and, for a carefully calculated moment, it seems humanity has solved something important. A gleaming capsule, four people floating, an orbit around the Moon, and a perfect staged scene to remind…...

16+ hour, 18+ min ago   (484+ words) The mechanical behavior of lunar regolith is crucial for lunar exploration projects, particularly drilling and sampling equipment. However, the extremely limited quantity of returned lunar regolith is insufficient for systematic macroscopic mechanical testing. Lunar regolith simulants are therefore widely used…...

18+ hour, 20+ min ago   (552+ words) Foliation-induced anisotropy in phyllite leads to complex deformation and failure responses, making excavation stability analysis and support design particularly challenging for geo-energy and geo-resource applications. To elucidate the influence of foliation angle (β) on mechanical behavior and fracture mechanisms, uniaxial…...

1+ day, 11+ hour ago   (269+ words) Researchers have discovered a thermal asymmetry deep beneath the surface throughout Mars's southern hemisphere. Based on gravitational measurements that give clues to the Red Planet's interior structure, Mars's interior southern hemisphere is around 200 to 400 degrees Celsius warmer than the northern…...
