‘Nanocardboard’ flyers could serve as martian atmospheric probes

O,.O woah!


This summer, NASA plans to launch its next Mars rover, Perseverance, which will carry with it the first aircraft to ever fly on another planet, the Mars Helicopter. As the first of its kind, the Mars Helicopter will carry no instruments and collect no data—NASA describes merely flying it all as “high-risk, high-reward” research.

With the risks of extraterrestrial flight in mind, Penn Engineers are suggesting a different approach to exploring the skies of other worlds: a fleet of tiny aircraft that each weigh about as much as a fruit fly and have no moving parts.

These flyers are plates of “nanocardboard,” which levitate when bright light is shone on them. As one side of the plate heats up, the temperature differential gets air circulating through its and shooting out of the corrugated channels that give it its name, thrusting it off the ground.
