I've read both.

That's an interesting concept.

What a beautiful dog!

I saw the documentary about this! It's really incredible, can't wait until they resume their search.

A bigger helicopter requires more rotations. More rotations require more energy. If we're talking about a ''regular sized'' helicopter on Mars, it would have to spin WAY more than 3,000 times per minute (a 4 pound drone spins 10x faster than helicopters on earth). At *least* 4 million times per second (4 pounds roughly 1,000 rotations per pound) based upon a weight of 1,400~ lbs. We just don't have that kind of insane energy, and frankly even if we could do it, space and the laws of physics have their limitations.

Especially since his fame made him an EASY target.

Hopefully, we'll look back and view the Ingenuity Helicopter as an early, primitive attempt, similar to the very first airplane concepts. 30 seconds may extend to 5 hours or more.

That's not true, you can switch their direction with concentration.
