Recent progress in hypersonic aerodynamics has shed light on one of the field's longest-standing puzzles: the unpredictable transition from smooth to turbulent airflow around blunt-nosed vehicles. This transition dramatically increases drag and thermal load, posing a major challenge to hypersonic flight systems.

Europe has advanced its ability to track extreme weather with the launch of the Meteosat Third Generation Sounder 1 (MTG-S1), the continent's first geostationary meteorological sounder. The satellite will deliver critical atmospheric data that supports earlier and more accurate weather alerts, helping to safeguard people, infrastructure, and economies.

Why is Mars barren and uninhabitable, while life has always thrived here on our relatively similar planet Earth?
A discovery made by a NASA rover has offered a clue for this mystery, new research said Wednesday, suggesting that while rivers once sporadically flowed on Mars, it was doomed to mostly be a desert planet.
