An Entomopter, on the other hand achieves abnormally high lift with rapidly flapping wings, and therefore allows the fuselage to move slowly in relation to the ground. The Reynolds number for flight on Mars is equivalent to that found at over 100,000 feet here on Earth. Nothing currently flies with any regularity at this altitude. However, the Reynolds number regime for the tiny Entomopter operating in Earth's atmosphere is equivalent to a larger version (perhaps one meter wing span) operating in the Martian atmosphere. In addition, the gravity on Mars is only 37 percent of that on Earth, so an Entomopter-based Mars Flyer would benefit by proportionately reduced weight, even at its increased size on Mars. An Entomopter-based Mars Flyer holds promise of not only flying slowly over the Martian landscape, but being a multimode vehicle, could land, take samples/recharge/or communicate, and then take off to continue the survey mission. It even has the potential of returning to its launch point for refueling, downloading of data, or transferring of samples.
