The Mars Helicopter, Ingenuity aims to make the first powered flight on another planet when it takes off on Mars. It has now landed and safely checked in with the rover. It should detach and fly within the first 30-60 days of the mission. I learned a lot getting to visit the drone right before it was mounted on the rover at NASA Jet Propulsion Laboratory in Pasadena.
How do you fly in 1% of Earth's atmosphere:
Have large rotors (they are 1.2m in diameter) and spin them very fast, around 2500 RPM (5x the speed of a helicopter on Earth).
Plus the aircraft has to be light:
The Mars helicopter weighs in at 1.8kg or around the same as a laptop. Every piece had to be stripped down for weight. Instead of using aerogel for insulation, the craft makes use of CO2 gaps between components. Even aerogel was too heavy!
One of the major challenges is surviving the Martian night:
Temperatures plunge to -80C to -100C so two thirds of the craft's power is actually used to keep its electronics warm. Only one third is used for flying. The estimated flight time is 90 seconds.
The craft can't be driven remotely, it will have to fly autonomously, using its own sensor suite to determine how to fly. The round trip 20 minute delay with Earth means steering the craft from mission control would be impossible.

Why did they do the complex pulley system to offset the weight instead of taking the batteries out and reducing the weight that way? Is there something I am missing? Maybe they want to test the entire system without any hardware modifications I suppose?

@ThiccDuck 95 Well, that depends on the season. Mars's atmosphere is about 100 times thinner than Earth's. Without a "thermal blanket," Mars can't retain any heat energy. On average, the temperature on Mars is about minus 80 degrees Fahrenheit (minus 60 degrees Celsius). In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).

Would the speed of sound not be slightly altered if said speed is in a less dense atmosphere ? And would this not alter the speed at which the rotors are able to rotate?
How Does it Really Work
The speed of sound does not depend on pressure, but it does depend on temperature and the elemental composition of gas. It will be -50C on Mars during the flights, and the atmosphere is largely carbon dioxide instead of mostly nitrogen on Earth. People at JPL know all that, and when they talk about the speed of sound, they mean the speed of sound on Mars.

How Does it Really Work
Great video, it was very cool to see and hear the creators of Ingenuity! But I really wish you would not have said that _"on Earth helicopters spin their blades at 500 rpm"_ (to contrast it with how fast Ingenuity's blades spin 1:45). It is indeed a very intuitive thing to say that Ingenuity flies in the thin atmosphere of Mars _"because its blades spin crazy fast"_ but the reality is much more subtle. The helicopters on Earth spin their blades in a very wide range of rpm, depending on the size of the helicopter -- from below 200 rpm for the large full size helicopters, to 8000 rpm for DJI drones. If we compare Ingenuity to the RC helicopters of equal size, we would see much more similar rpm. RC helicopters with the rotors of the same 1.2 meter diameter as ingenuity (550 or 570 class) spin their blades at 2000-2500 rpm and even faster for some aerobatic flying. This does not, of course mean that Ingenuity is just another off-the shelf RC helicopter -- or course it is different in many parameters! But even though it seems counter-intuitive, the rpm is not one of these differences that make it fly on Mars. It would be more meaningful to say that the very wide and specialized rotor blades of Ingenuity could lift it on Earth with just 500 rpm (if it had sufficient torque, strength etc). Then, 2500 rpm on Mars is indeed very fast in comparison.

I'm curious as to why they didn't just attach the fishing line, through the pulley, to something 62% the weight of the chopper... surely that means that the amount of weight it has to lift is only 38% of its original weight
How Does it Really Work
That would only work perfectly when the helicopter does not accelerate up or down. If it does accelerate, then the actual mass of the helicopter plus the mass of the counterweight would be accelerating, and that would require a factor of (1+2/3) more force vs just the force to accelerate the mass of the helicopter itself. So the dynamics of the altitude control would not be quite the same. I do not know if that was important or not. One could also imagine using a long rubber band to pull the helicopter up with a force that is approximately constant, but that would also not be quite as perfect as the more complex system which they have implemented. It would be curious to know if there was some really important reason to do it the way they have done it, or if people at JPL simply have a habit to always do things in the best way possible.

@Bobby Vincent If the craft is light enough, then I suppose it doesn't need big beefy legs. Besides, it won't do any serious work. It's "only" goal is to test if such a drone/helicopter is a viable way of exploring Mars (and take a few pics along the way/test the navigation software). If it succeeds (meaning: it will be able to lift off, control it's flight and land), then it will create a path for future, more advanced crafts.
