NASA rover detects ultrafine Martian dust, a potential challenge for human missions

New data from a NASA rover show that Mars’ dust includes ultrafine particles, adding detail to a persistent environmental hazard. Dust moves through everyday winds, dust devils and storms at local, regional and global scales, making its behavior a factor that mission planners must address for future human exploration.

What Hype is tracking

Ultrafine dust adds to the environmental data needed to assess hazards for human missions to Mars.
Dust is transported by winds, dust devils and storms at multiple scales, so understanding its movement is relevant to mission planning and operations.
