thanks
Through Huawei networking equipment? What could go wrong?

They had a watchdog timeout that rebooted the drone; it happened when they tried to spin the rotors up to 2400 rpm (which I have to admit is pretty fast for blades that big).
Not enuff aaare!
down here that would be impressive, 2400 rpm
thing would be shooting skyward in no time
but its such a thin atmosphere there
like swimming in air
“Not enuff aaare!”
Agree, they should have considered the atmospheric conditions when they designed it.
When you think about it... getting all the software bugs worked out before a critical launch date could become impossible. So re-programming during the mission has to be an option. Cuz you never know.
The rotor span is ~4 feet. (1.2m)
The larger RC helicopters here on earth have rotors that span about the same and spin about the same speed.

They have blades that are narrower in chord, but that's because of the thicker atmosphere.
Ingenuity's blades are shaped more like propellers than typical helicopter rotor blades because they would get more 'bite' in the Mars atmosphere.
It’s actually pretty standard. They work on the software all the way through the flight to Mars. There’s no reason to have the software all done before launch, that just loses months of dev time. Most of these things don’t get the mission software until it’s needed, landing sequence gets transmitted as it’s getting there, rover movement software won’t get loaded until after it lands. And then there’s always tweaks. Anything they look at and think “that could do better” they work it.
yeah ive seen the nitro-powered ones in action and they spin pretty fast.
The launch window to Mars is a pretty firm date. Your software development can be more flexible to ease the strain on the mission planners.
NASA has got to stop using Windows 10.
Yup. I got a friend who worked on one of the missions, not the one that augured in, and he told me about it. At launch time they basically only have enough software to get software updates, cause that’s all it’s gonna need for a few months.
I wonder if they equipped it with some way to get itself upright if it does tip over. I guess the rover could give it an assist if it’s not too far away.
You mean the Wicked Witch of the West?😳
Yep. NASA has been moving flight dates like crazy.
NASA would have been better served by just saying Flight date
would be scheduled after successful Pre-Flight test(Which wasn’t successful).
Hilarity of the century is someone hacks it and flies it for them.
the context was 2400 rpm with those particular blades
Because the rotors have adjustable pitch like RC and full-size choppers, this bird would only climb as fast, even at 2400 rpm, as the pitch would dictate.
