Here’s how NASA tests Mars rovers on Earth

I have a neighbor that has one of those.

Interesting. The rovers are much bigger than I imagined.


They’ve also tested them at Kata Tjuta in Australia. The crumbly rocky soil there is extremely similar to Mars.


presuming that rubber deteriorates from radiation


I’m curious as to how they have tried to match the soil mechanics, because the differing amounts of air, water, and gravity have the potential to make it VERY different.


Yeah, I image that even at their best they just have to wing it at some point. That’s always been my perception of the people at NASA; insanely brilliant, detail-oriented and thorough people who occasionally have to just say “Fuck it, we’re as ready as we’ll ever be. Push the button and let’s see what happens.”
