@@juzoli Actually, whether laser can be blocked by clouds depends on the wavelength of the laser, the type of clouds (dust vs droplets) and the size of the particles. For example, if we're talking about fog clouds, infrared laser could still work; and Lidar is in fact typically outside the visible spectrum (for that very reason, among others).

@StuffMadeHere 3 роки тому
Very cool but so many questions! The biggest question on my mind is why numeric / software simulation is not adequate for developing and testing the control system? Relatedly, what is the rationale for using moon gravity for tests like obstacle avoidance / site selection? It seems like those systems would be totally orthogonal to the gravity situation (i.e. what the camera sees / choosing a site doesn't change with gravity). I know there must be some intricacy that I'm missing and inquiring minds want to know! My other question is why does the X axis point up. There must be a story there since that is obviously unnatural and an abomination :)
@stealth6403 3 роки тому
hahah here before people notice u
@philipcooksey3422 3 роки тому
My guess would be they were doing multiple tests while doing the obstacle avoidance, so collecting data for the 1/6 g in addition
@Vimarsh24 3 роки тому
I was also wondering.. like why can't we just simulate everything. We have enough computing resources to do that.. Also the lander can easily do edge computing to figure out what to do based on cameras.. Definitely missing something
@oscassey 3 роки тому
Simulation gives you confidence and is what allows you to proceed to these real-life conditions tests. And also consider that simulators could have bugs, outside does not have bugs (well, other kinds of bugs).
@thelog222 3 роки тому
Nothing beats real test hardware and flight data! There's often some nuance or interconnection that you learn about. The intent of the program was to simulate everything as close as possible to flight so while you're right that testing things like hazard avoidance doesn't inherently require moon gravity, it was nice to get even closer to what the actual landing would look like. From what I remember of the axes decision, you roll about your X axis so it made sense. Landers are not airplanes!

Well, the main alternative, various hydrazine compounds, are super nasty. They can ignite on contact with your person, mess up your lungs, cause kidney or liver failure, and are carcinogenic. Anyone handling the stuff (or getting near a vehicle that has used it) has to wear a chemical suit with independent oxygen supply. They're more energetic than peroxide, but unless you really need that it's not worth it.

The propellant I use in my rockets is almost perfectly safe: a combination of pressurized gaseous nitrogen and oxygen (and some other things) and H2O. But I suppose even that could kill you if you got enough of it in your lungs!

I love redundancy! There's nothing like it when it comes to saving a sortie/mission and the primary system goes TU. But redundant systems are only as good as the operators who recognize when a system is not operating properly. Remember a French Airbus 320 that went down in the Atlantic a while back because someone failed to turn on the pitot heat? Too much dependence on the automated system is what that came down to -- or because. So redundancy coupled with LOTS of pilot training is a GOOD thing!

If there's one thing NASA has demonstrated, it's that things can and will go sideways at some point. It's not "if" something will go wrong, but rather "when" something will go wrong.

What you say around the 23:00 timemark is soo important. It's exactly the same with the ongoing automatization in airplane cockpits. Pilots lose their flying skills and if an emergency situation occured where they have to take over the controls because the software failed, it will end badly...

@@nataliarodriguez3740 I think that chess is different since the computer has no sensors that can give it false information, as there is only the chessboard. Then there is no unknown variables for the chess AI other than which move the other person can make. Lastly, the AI has a relatively simple set of rules where it can predict all outcomes. Chess is the perfect scenario for an AI. Real life is different in that sometimes the computer/AI can misunderstand what it is recieving, sensors can fail, the computer itself can fail, or the computer encounters a situation it was never programmed to deal with. Human control, while hopefully never necessary, is very important if the spaceship encounters a strange or unexpected obstacle IMO.

Just completely different strategies. Spacex wants it to be entirely autonomous so having a human in the loop would ruin that. Also with their rapid prototyping strategy the data they collected was more than worth the cost of the damaged starship

@@philipcooksey3422 I'd rather have a safe craft than a "strategy" he's living life like a video game. Rocket blows up, reset, try again. I guess that's a fine strategy for testing, but I'm sure that if there was a multi million dollar payload on that, I'm sure those people wouldn't appreciate their stuff getting blown up and being shrugged off in such a manner.
