NASA Wants to Put Drones to Work on Mars

NASA plans to fly drones where Federal Aviation Administration rules no longer apply.

Engineers at Swamp Works, part of NASA and the U.S. military’s Office of Naval Research, have designed and built a drone that could someday scout Mars, moons or asteroids in our solar system. Called Extreme Access Flyers, these space-worthy drones could help scientists gather data in places your traditional rover just can’t reach.

Cosmic Drones

It’s hard to debate the Mars Curiosity rover’s legendary status, but there are some things it can’t do. Like our own planet, Mars features rough, jagged terrain with crater walls angled at 30 degrees or more. Curiosity can’t explore these double-black-diamond locations. So researchers are designing drones that could simply fly over these obstacles.

By the looks of it, Swamp Works’ drone looks a lot like the quadcopters we routinely see, but researchers made serious modifications to make the craft spaceworthy. In the ultra-thin atmosphere of Mars, or the airless vacuums of asteroids, rotors are useless. Instead, space drones rely on cold-gas jets for lift and steering capabilities. A planet-exploring drone also needs to be fully autonomous: The communications delay is far too significant to fly a drone on Mars from Earth.

Researchers believe space drones would serve as single-function “prospecting” instruments. They could be used to scout new places, or perhaps take tiny soil samples from hard-to-access places — like a cliff, or the dark side of Mars. Getting access to previously inaccessible places is a running theme at NASA right now. The space organization is also working on designing “windbots” that would harness wind energy to explore gas giants like Jupiter.

Build, Test, Repeat

Swamp Works engineers have built several models of their space drones, each designed to test aspects of the final product. The team believes their latest prototype, a 5-foot-wide, cold-gas-propelled drone, closely resembles what you might someday see flying in space. They are loading their prototypes with navigation software that helps the drones recognize and react to physical features in their environment.

Five years ago, researchers couldn’t even consider building a space drone. But advances in 3-D printing, autonomous flight controls, laser guidance and mapping systems make it much more likely that Swamp Works’ prototype will someday make it off the face of the planet.

    It will be impossible to keep the drones from shining laser lights in the eyes of the orbiters and rovers, firing guns in Martian theaters for NRA promotion videos, and ogling pre-adult Martians skinny dipping in dust wallows.

    When did the FAA relax it’s rules with drones on Mars ….poor journalism

    Hydrazine, a decomposition catalyst, and de Laval nozzles would skirt the boundaries of making sense energy-density-wise. “Cold-gas jets” for Mars aerial rovers are a NASA blow job. We will not tolerate the unknown hazards of compromising Martian ecology with discarded fiber-wound composite fuel tanks. A fragile and endangered species might ingest said tanks, then conspire to cold-gas propel themselves to Terran invasion and conquest. It’s all downhill, right? Good mileage!
