Marks on Martian dunes may be tracks of dry-ice sleds

(Phys.org) —NASA research indicates hunks of frozen carbon dioxide—dry ice—may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.

NASA image: Frosty slopes on Mars

This image of an area on the surface of Mars, approximately 1.5 by 3 kilometers in size, shows frosted gullies on a south-facing slope within a crater.

Frosty cold nights year-round on Mars may stir dust

Some dusty parts of Mars get as cold at night year-round as the planet's poles do in winter, even regions near the equator in summer, according to new NASA findings based on Mars Reconnaissance Orbiter observations.

Beetle-inspired discovery could reduce frost's costly sting

In a discovery that may lead to ways to prevent frost on airplane parts, condenser coils, and even windshields, a team of researchers led by Virginia Tech has used chemical micropatterns to control the growth of frost caused ...

Leaf-inspired surface prevents frost formation

Northwestern University researchers discovered a new way to significantly reduce frost formation on any surface. The finding could help decrease the amount of energy needed for de-frosting and could potentially result in ...
