Why is nobody worried about the helicopter crashing to the rover and possibly destroying a science instrument? How far will the helicopter be from the rover?
- ncallaway 6y agoI would imagine that NASA is extremely worried about that, and has gone to great lengths to ensure it's not an outcome. Why do you assume that nobody has worried about this, or considered this contingency?
- NikolaeVarius 6y agoBecause NASA isn't full of idiots.
- cosmonaughty 6y agoRight. They are very clever. They are clever enough to have all of you believing this AVR enhanced cartoon was a real Martian landing. If those helicopter blades spin 40x faster than a real chopper at sea level air pressure on earth, the turbulence alone would disintegrate the flywheel and blades and destroy the whole thing. So how did they test it? Let a experiment explain it: https://m.youtube.com/watch?v=8Cx9mNnky2U https://m.youtube.com/watch?v=8Cx9mNnky2U

So how did they test it? The obvious method would be a large vacuum chamber, evacuated enough to simulate martian atmospheric pressure. Google it and, yes, that's exactly it. https://en.m.wikipedia.org/wiki/Ingenuity_(helicopter)#Testing https://en.m.wikipedia.org/wiki/Ingenuity_(helicopter)#Testi...
- cosmonaughty 6y agoThe link I posted points to a YouTube video of a vacuum chamber reduced to "Martian" pressure. It should have been obvious that my question was rhetorical, and that I provided the answer. Watch the YouTube video and compare it to the AVR cartoons that NASA is giving for millions of dollars per day.
- dragonwriter 6y agoYour post was sneering at the idea of it being real, and I generally don't click on video links without a clear idea of what they are (because video is a low-information-0er-time, high-emotional-engagement medium, and experience has proven that it's almost never worth doing) and I'm even less likely to do so with the implied content from the rest of your post.
- cosmonaughty 6y agoWell then might I suggest a video on the official NASA web site? https://www.nasa.gov/feature/jpl/mars-virtual-reality-software-wins-nasa-award https://www.nasa.gov/feature/jpl/mars-virtual-reality-softwa... There are much better video specimens of science experiments on YouTube.
- adrianpike 6y agoGoogling NASA + AVR led me down a rabbit hole towards Atmel microcontrollers, what do you mean by AVR in this context?
- cosmonaughty 6y agoAVR = Augmented Virtual Reality. It's like CGI on steroids, crack, and speed at the same time. People still have the naivete to trust things because they are on a screen. Preconceived notions cause one to mentally miss or gloss over the great artistry and manipulation in AVR cartoons. The vid is worth the few minutes. It is a half decent scientific experiment that shows how rocket propulsion really works, and it shows an extra factor left out of the Newton's law argument: Ejective oxidation cannot occur without atmospheric containment pressure. Countless experiments have proven this. Buyer beware what they show you on a screen.
- upbeat_general 6y agoI’m pretty sure this was one of the main criteria for building the helicopter since the -reject is not essential to the mission but is instead is a demonstration. It’s probably also why they’re waiting to fly it so that the rover is a bit further away
- shawnz 6y agoThe helicopter is itself also a science instrument. How do they prevent any of the instruments from destroying each other? Careful planning, I would guess
- cosmonaughty 6y agoNot really a scientific instrument...more of a stage prop.

- holoduke 6y agoOf course they worried. That's why the first flight will just be a accent of 3 meters.
