The guy that tied up the wiring on the side there is looking at this photo (probably) and saying to himself: that wiring I arranged is on motherfucking mars and that's just crazy.
They're gonna drive that thing till the wheels fall off.
And the little bugger is still chugging along. Amazing.
I feel this. It's not the years, honey. It's the mileage.
That thing hasn't even traveled 20 miles I think. Going to say it must be getting a lot of damage from winds or something. Someone said it is aluminum.
Im tired, boss.
What I'm curious about is the "engineering model."
All NASA missions have duplicate probes, satellites, rovers, here on earth. They're essential for testing various scenarios like training astronauts (in the case of the Hubble repair missions), or testing the limits of the systems in question. I wonder if the engineering model for Curiosity has one of its wheels cut away in the same pattern, to simulate difficulties in navigation and traction?
Maybe that's why the took the photo of the wheel?
Now that you mention it, that's probably why.
iirc, they did use a damaged wheel to try to figure out a situation where a rover was stuck, though I don't remember any details about it.
Man that wheel is so much thinner than I was expecting. I was surprised it was broken at all until I noticed how thin the material is. That looks like it's less than a quarter of an inch of what appears to be rigid material for something about the size of a medium-ish car.
It was just thick enough to hold well past the initial mission time. That means any thicker would have been a waste of materials, weight, and energy. If anything, it was too thick. Every gram counts when bringing objects to space.
It’s thicker than it looks because the rover is much larger than it looks of course proportionally it’s still thin but curiosity is lighter than it looks because it was made for space snd mars is smaller than earth.
It was getting damaged pretty much as soon as they started using it. It's kinda weird they didn't catch something like that in testing on earth? Were the rocks on Mars just that more jagged?
But also I think the wheels are aluminum as well, so very soft metal.
Designing any kind of space vehicle is always a trade off.
The vehicle needs to be light enough to be launched from earth to mars, but durable enough to fulfill its mission goals.
I’m sure if nasa had access to a vehicle that could send an M1 Abram’s sized, solid steel rover to mars, they totally would, but that would probably cost more than a moon mission, and the whole point of rovers is that they’re fairly cheap for the amount of research you can get out of them.
It's lasted this long. I think they made the right decisions. No matter what it is, it's going to be damaged. The goal is to make it still operate despite the damage for as long as possible. The goal isn't to make it last forever, or to never be damaged. The more massive the wheels are the less mass everything else can be, so it's a big trade-off.
Yes rocks are more sharp on planets or moons with no or very little atmosphere because erosion by wind/rain forces is reduced.
You're saying we've polluted Mars with microplastics too!?
It's okay, Mars is low on fossil fuels and could use some global warming, so the Martians are already burning it as we speak.
Not just Mars, but yes. Biodegradability isn't even a factor since there's no biosphere to speak of, which also raises philosophical questions like: "what is pollution, exactly?"
What will really bake your noodle is to imagine a future where we settle the Moon and Mars. Do old space program artifacts become monuments and parks (debris and all), or are they trash to be removed from the environment?
Knowing humans, yes! I think they will. Probably not the bits that fall off, they'll most likely be placed in the visitors centre but given how sentimental we are as a species I can absolutely see us one day touring the sea of tranquility space reservation.
Removed, obviously. Gotta put that new STARbucks somewhere
