After the rover released it and cleared its takeoff trajectory, the helicopter was then supposed to take off. The comic projects what might happen if the mission controllers activated the helicopter early and the entire rover took off from the surface. |
+ | In the comic, Ponytail and Cueball are standing at mission control, when Cueball slips and hits the button. The Ingenuity drone then takes of, lifting Perserverance with it, and the rover says "Wheee!" Presumably from excitement or happiness. | ||

Mars may have less gravity, but Mars' atmosphere is 1% the density of earth. [https://www.youtube.com/watch?v=aYe3sIaNHVs It's so thin that you couldn't move a feather with a fan.] This is why the character mumbles his explanation of the science, because they know any explanation doesn't actually make sense. |
The total mass of the two vehicles is about 556 times that of the helicopter alone, meaning the unexpected lift effect 'described' would have to be several hundred times more effective than that anticipated, depending upon the factor of overdesign already built in to avoid an expensive marginal failure. It also seems to be trivially easy to balance the extremely top-heavy loading upon the small solar-panel that tops out the counter-rotating coaxial blades, which adds yet more questions of both the dynamic and structural performance, never mind questions about the available power to accomplish this and the later possibilities to recharge. | The total mass of the two vehicles is about 556 times that of the helicopter alone, meaning the unexpected lift effect 'described' would have to be several hundred times more effective than that anticipated, depending upon the factor of overdesign already built in to avoid an expensive marginal failure.
