A deep technical analysis of atmospheric re-entry thermodynamics: Rankine-Hugoniot shock relations, Fay-Riddell stagnation heating, ablative TPS mass pyrolysis, plasma sheath ionisation, and the non-equilibrium aerothermochemistry that defines the design envelope for every crewed vehicle returning from orbit.
NASA has announced the Artemis III crew for the first crewed lunar landing since Apollo 17 — targeting the south pole and its permanently shadowed water ice deposits.
Ice confirmed at the lunar south pole changes the economics of deep space exploration. How LCROSS found it, what ISRU means for a lunar economy, and why water on the Moon could be the most strategically important resource in the solar system.
Lunar regolith hazards go beyond abrasion. Razor-sharp, electrostatically charged, and potentially toxic to lungs — here's what makes moon dust a primary engineering challenge for every Artemis surface mission.
