What would be way cool is if it had a motor.

With the extreme "thinness" of Mar's atmosphere, that 'wing' had better have a very HIGH-lift aspect ratio.

I can see this being constructed out of materials such a composite of carbon or steel aerogels, carbon nanotubes, and two dimensional sheets layered in the right proportions and printed rigid in the right spots and interleaved to prevent crack propagation.

The atmosphere of Mars is 0.6% of Earth. Yet the red planet's gravity is 38% that of our planet. Which is roughly 63 times more difficult to generate lift. So, you need to make trade offs in surface area, weight, and speed.

I just don't see their current prototype working on mars without moving too quickly. My gut says, better to go light.

I found a few good videos showing the properties of the Graphene Aerogel along with one printed from metal that floated on a dandelion yet had the strength/toughness close to a dry sponge. With a reinforcement of a stiffer material in the right places, you would have a plane that would stay afloat rather than merely just glide down to the surface.
