Hello.

I went to my local astronomy club last night and the subject of diminished solar power caused by dust came up in conversation. We looked at images of the Insight mission and these showed a significant build up of said dust. This got me thinking.

Could the solar panels of future Mars probes be designed to use cymatic cleaning? A controlled vibration passing through the panels might cause the dust to move in a planned way. If the panels themselves were shaped in some way as to take advantage of this then could the dust be somehow 'channelled' away from the solar cells?

These are just ideas that occurred to me, by the way. I'm no engineer or acoustics scientist. Do you think there's any mileage in my idea?

Thank you.

Cerenkov.

That sounds plausible to me. Power consumption would be a concern.

You should try to research NASA publications to see if they have investigated vibrations as a method of cleaning the panels. My guess is that any idea such as yours that has promise would have been investigated.

If not, then maybe you could apply for a research grant. The idea would have to be proved in a laboratory before gaining credibility.

Thanks anorlunda.

As I said, I'm no engineer, but if I had to hazard a guess about power consumption, it might run something like this.

The earthbound demonstrations of cymatics that I've seen seem to show that only a brief period of vibration (several seconds?) is needed to achieve a desired result. If that power expenditure is enough to clean the panels for a period of days or weeks, then I think the trade off might be worth it. Whatever you power you lose cleaning the panels would be gained back by the improved efficiency of more sunlight hitting them.

But, that's just a guess.

Thanks,

Cerenkov.

So I was sitting in my car today as it went through the car wash, and I was wondering the same thing -- what kind of simple mechnism could be attached to the solar panel assembly to periodically clean it off? There must be something that can be done... :wink:

The Perseverance Mars mission has the Ingenuity drone copter. I wonder why they don't use the drone to blow the dust off the Perseverance solar panels. Maybe they do.
But not blow the dust from the ground up on to the panels? I'd bet it could help, but it sounds a bit tricky to me.

Flying that close to the rover sounds like a big risk. It could also add dust from the time before/after Ingenuity is above the rover.

Well, sure. Certainly a possible direction for future research.
It's just... At this point the InSight mission is long over the originally planned length. The fact that the problem popped up so late indicates that the plans for the original timeframe of the mission were sound, no solution were needed for no problem :smile:

Erm... For as many as Perseverance has, gremlins would do too :wink:
