”Could moon dust help stop bleeding in space?
When astronauts venture beyond low Earth orbit on long-duration missions, emergency medicine becomes a critical challenge.
Payload constraints mean that traditional medical supplies may simply not be available, so what if the answer lies in the ground beneath their feet?
A new study in RPTH Journal investigated whether extraterrestrial regolith, the rocky and dusty material found on the Moon, Mars, and asteroids, could serve as a haemostatic agent in space trauma care.
Key findings:
- Lunar and Martian regolith simulants, as well as meteorite samples, accelerated clotting, thrombin generation, and FXII activation in human plasma. Procoagulant activity was reduced in FXII-depleted or FXII-inhibited plasma, confirming an FXII-dependent mechanism
- Phyllosilicates showed greater procoagulant activity than framework silicates. In a porcine model of penetrating haemorrhage, wounds treated with regolith remained clotted longer and lost less blood than those treated with gauze alone
