[@Bloodline2009]

Solar panels and dust always seems to be the reason missions don't last longer on Mars, you'd think they would design a specific shape or dust resistant properties or even a fan jet arm to blow them clean. Interesting this has not been tackled yet.

[@jhaz89]

I have no doubt it's been considered and they decided the cons outweigh the pros. These are really damn smart people making these decisions. So it's easier said than done. And once again, it's lifespan lasted much longer than expected.

[@Appletank8]

The mission for Ingenuity was designed for 30 days only. Adding other components intending to extend it adds cost and weight. Spirit and Opportunity were designed for only 90 days. Oppy going for 15 years is great, but wasn't planned for.

[@bigsarge2085]

Incredible!

[@shkiper4224]

With all the engineering in to these robots, why didn't they made robo hand with a brush to wipe dust from those solar panels.

[@randomautonomousdronepilot3384]

This is why you’re not an engineer 😂

[@bazpearce9993]

It was only a 30 day mission initially. So adding panel cleaning tech wasn't really needed for Ingenuity. But i do agree with you about a cleaning system to be invented. Perhaps an air chamber could be used to collect atmosphere, and keep piling it in their until it could be released at high pressure to blow dust off panels. The main reason cleaning systems haven't been used is all the weight capacity is all used up by science gear. Every gram counts on these missions.

[@majinvegeta9280]

Well said sir

[@WaterPickle]

@@randomautonomousdronepilot3384 and you are ? 💀

[@fhkwanders]

Such a arm costs a lot of power and mass, resources that are most valuable in space. Also the scraping of dust can damage the panels and the winds on Mars generally do a good job in removing the sand and dust. The engineers did of course consider it, but decides that the benefits did not outweigh the costs.

From 10:04 - The Ingenuity helicopter began to malfunction because of dust covering its solar panels. But surely this should have been foreseen - couldn't a small windshield wiper, or something similar, have been fitted to it, to keep the panels clean?

[@reinatycoon3644]

I loved this video, all your videos are just so damn well done man! Maris is speculated by some to have formed life only 400 million years after it's creation way sooner than our lovely Earth did. This is because it is smaller and as thus lost heat from it's creation faster than Earth did to a habitable and water sustaining level. IIRC it is thought that Mars became geologically inactive, cooled, down and lost liquid water on it's surface entirely around 1.5 billion years ago or so. Meaning life very well could have thrived there for a good 1.8 billion years giving rise to bacterium and plankton type life if life evolved there at an earth similar rate. when I see Mars and really take the vibes, energies, and everything in deep I get the strongest feeling of a history of life, i can't really explain it. I honestly think life was there with a 100% certainty. If only Mars was lucky enough to have captured a satellite that was at least 2000 km in diameter with decent density orbiting ~100k km away. This would have kept Mars's core hot longer from tidal forces flexing and heating the core through friction. This would have kept it geologically active with volcanic eruptions constantly resupplying gases to the atmosphere. If this were the case life would still exist there and who knows how much it would have evolved... maybe even intelligent life?! It's really a shame it had to go down in the manner in which it did. Mars only captured two asteroid sized satellites ugh.

Surprised a method of blowing the dust from the solar panels wasn't built-in to Ingenuity or the Perseverance Rover. Certainly should be included on any future missions utilizing solar power.

[@Appletank8]

If the mission only wanted to go for 30 days, then it's perfectly fine. Going over is a pleasant surprise. Oppy was intended for 90 days, solar will work for 90 days, and is cheaper than a nuclear reactor or adding a brush system.

[@dcorman]

@@Appletank8 ???

[@dcorman]

@@Appletank8 Still, surprised. Because anyone on the mission project should have suggested a low power fan, or using Ingenuity's rotors to clean off solar panels. As it is a recurring, and mission critical, problem which anyone could argue should have been a primary mission consideration.

Why can't the dust be blown off the solar panels once the dust storms end. Would the weight of such a device be too great to include?

The batteries will probably die from the chill. Batteries don't do well when kept freezing for long periods of time.

This is another argument for solar panels that can clean the dust off themselves. Perhaps like leaves, small holes, with a cap to disperse a gas can blow dust off. A simple fan system could blow clear the most productive areas of the panels?

weight, cost, space for more or better sensors.

[@theslenderfox]

@@FransBlaas1 It's just that it seems like the main thing ending mars missions is the solar panels being covered with dust which severely reduces the operating power, if they just wipe the solar panels every now and then they'd have way more power to work with. Also I don't think it would be that much extra weight right?

Couldn't they have some of the solar panels on the wings, so they self clean as they fly?

[@niklar55]

ALL the Mars rovers have suffered from the same problem of dust on the solar collectors. It seems to me, that it should not be beyond the wit of man, and also, a priority, to devise a system to periodically clean the dust off the collectors. This could be done in several ways. Either by inverting the collectors, so the dust falls off, or maybe by just blowing the dust away, with something like a miniature leaf blower. Wiping would not be good as this would scratch the collectors. Maybe just tilting them a little, and either vibrating them, or a small 'hammer' shock, would work, or maybe electrostatic repulsion. Maybe there's a surface treatment that would facilitate dust rejection. It would need tests to ascertain the most efficient and least power usage system. Perhaps something from nature, like dragonfly, butterfly wings, or some other insect, could give the answer. .
