Self preservation is a strong basic motivator. It’s extremely rare for an individual to both have enough desire to do something radical with planning while also lacking the will to keep living.

Based on locations they like to overcharge and sell at a premium.

Edit: nothings wrong with that, it allows for premium ingredients and care. But you do need a certain amount of clientele with money that not all towns/cities can support.

Heeeeyyyy!

Yeah that was why I was wondering about stuff like 0.9nm. Pm won’t be recognizable to consumers and consumers will be confused that it’s a larger number.

So at some point with this convention will we use negative nm? Or will we just drop to 0.9nm 0.8nm etc?

I doubt the atmosphere is thick enough for the air to have enough force to move the dust at all sadly.

Or Martian dust is like little razor blazes and a wiper would scratch up the panels badly. A rotary makes more sense but the dust is static and some would still stick. Also a rotary is a lot of weight if it can move all the panels with good speed.

There may be a lot of clowns but NASA is not among them unless it’s a case of congress mandating something to them.

Made a top level comment with more detail, but Martian dust is static so compressed air wouldn’t work well. Also that’s a pretty big and heavy system if you want any power.

Seeing lots of comments with simple suggestions. It’s NASA if a problem exists still it’s because it’s harder to fix than it appears. IIRC Martian fines have a strong static charge and love to stick. Compressed air wouldn’t work well. Also Martian fines are very rough, so wipers would tear up the panels.

They have come up with some cool repellent systems for their space suits using electric currents in the last few years. I am guessing they will work to implement that tech with new rovers.

Lunar fines are a bit worse then Martian ones but they are very similar issues.
