Its a cute prototype that stretches the imagination but is a wholly improbable design to find its way to Mars.

The weight and dimensions alone would make it very, very difficult to de-orbit onto the surface of mars. This thing weighs: 5,500 lbs. (2,500 kilograms).

Its not going to be very economical to get it out of earths gravity and into orbit just to start, forget about the energy it will require to get it moving towards Mars.
