On the aerodynamic side, this aircraft has a mass of 1.8 kg / 4 lbs, which is an equivalent weight of 0.7 kg / 1.5 lbs on Mars. That is also the force required to maintain altitude. Imagine picking up four or five apples; that's what we're talking about as a minimum to stay in the air. For comparison, a DJI Phantom weighs 3 lbs, and a Mavic comes in at 2 lbs.

I can't find numbers on the power system or materials so I can't speak to the thermal side or how much flight time that affords.

EDIT: Apparently there's enough energy to fly for 90 seconds (!) per sol.
