Simulating extraterrestrial environments on Earth has always been a challenge. Our planet has a pleasant atmosphere, reasonable temperatures, and a moderate amount of gravity, unlike the rest of the solar system. Or maybe that’s just because we think that way because we adapted to how it is here as we evolved here. In either case, the physical environment here makes it difficult for us to set up test environments that can accurately test probes going to other parts of the solar system. Many times, it involves vacuum chambers, air conditioners and heaters pumping hot and cold air into them, and soil simulant - lots and lots of soil simulant. But, according to a new paper from researchers at the University of Wisconsin-Madison, we’ve been neglecting one important aspect of these tests, and it might be the reason Spirit eventually got permanently stuck on Mars - sand is affected by gravity too.
