Mars Dust Poses Health Threat to Future Astronauts

As humanity turns its gaze toward Mars, an ancient and invisible adversary awaits: the planet's own soil. Martian dust, shaped by billions of years of oxidation and radiation into chemically reactive, microscopic shards, poses a profound threat to both human health and the machinery of exploration. Scientists and engineers are now engaged in the quiet, unglamorous work of understanding and containing this hazard — work that must be completed before any human footprint can safely mark the red planet's surface.
