- NASA’s InSight lander touched down in the Elysium Planitia region of Mars in November of 2018. During its time on the Red Planet, InSight has achieved all its primary science goals and continues to hunt for quakes on Mars.
The mission is the first to reveal the interior structure of Mars, using marsquakes to study the layers inside the planet. InSight’s seismometer was the first to detect a quake on another planet. InSight also measured weather at Elysium Planitia for four years with a unique set of meteorological sensors.
InSight has also persisted through adversity. The team found innovative ways to take on engineering challenges they encountered. InSight’s findings help scientists understand how all rocky worlds, including Earth and its Moon, formed.

Lesson learned: integrate a way to clean the dust on the next lander ✅
A small duster brush attachment. The glass surface of solar panels is strong.
It will not clean completely, Opportunity for example. Curiosity has far better energy sources (10 years and still rocking)
Not worth the extra mass and complexity. Every gram wasted for things like that is every gram that cannot be used for science, which is the entire point of the mission. The lander was only intended to last 2 years so it's outlived the time they thought it had.
@@Quest_NPC_ the problem is the power resources, the more instrument you have, more power needed to power the lander
Or simply use radioactive power
Thank you NASA and InSight!
Next time someone says my room is dirty I am going to tell them I am cleaning with dirt, just like NASA.
Awe this made me tear up a bit
I have read some comments below, and whatever people have suggested requires Battery Power which runs the lander, something that cannot be used very much as the power needs to stay longer with the lander. Great ideas though if power could hold out.
👋💕
Ребята! Молодцы! Делом занимаетесь!!!!
¿No se pueden volver a plegar los paneles como un abanico cambiando el sentido de los motores y después volver a extenderlos como la primera vez?
That's so fasinating!!!
Where can we read about the data on the interior of Mars? Is there a paper somewhere?
Yes right , we need full Transparenz because its our Right Like yours .For all.
exactly pointless video, gave no details and this is a nasa channel
Why can't we close and reopen the solar arrays so that some dust falls off, and for future missions, we should utilise nano coating on the solar arrays?
So how much jet wash does the perseverance drone put out in the Mars atmosphere? Could a package drop near Insight with a drone and charging platform be made and let the blades blast dust off the panels?
That guy got a tattoo..a space fanatic!🚀.. good on him👍
Very gentle, rotating brush wheel on lander arm to remove dust?
That would have meant more complex engineering and more parts to fail and extra mass. That would make the lander heavier, which, considering the mass is limited by what they could safely land, would mean less mass could be devoted to the science payloads. Every gram added to the lander is a gram that cannot be used for science, which is the entire point of the mission. Mars dirt and dust is not like Earth's. It's finer and more 'sticky' due to static etc. What would you use to clean the wheel? The lander was only intended to last 2 years so it's outlived the time they thought it had.
Whats the name of the used songs for this video especially the secon one round about 1:50 min
Why can't you use the robotic arm to pull out the probe and drag the soft cable that powers the probe over the surface of the solar panels to scrap away some of the dust to increase power production?
How have you guys not thought of adding some kind of paintbrush to the Rover to clean off its solar panels already?
That is extra parts, extra engineering, extra mass. All of which adds to the cost, complexity and reduces the mass available for the science payload, which is the entire point of the mission. Insight was only designed to last 2 years. It's exceeded that.
How have you deluded yourself into assuming you had some engineering epiphany that the engineers at NASA were incapable of???
If you're making a robot arm on a lander/rover anyway, why not add a feather duster attachment?
Or some cloth to pull out and wipe. The glass on solar panels is pretty strong. I clean mine with a broom at home
@@reaj2010 Mars dirt and dust is not like Earth's. It's finer and more 'sticky' due to static etc. What would you use to clean the broom / brush etc? Then there is tmore complex engineering and more parts to fail and extra mass that would all entail. That would make the lander heavier, which, considering they were limited by what they could safely land, would mean less mass could be devoted to the science payloads. Every gram added to the lander is a gram that cannot be used for science, which is the entire point of the mission.

RIP InSight.
I hope Starship crew finds it and brings it home
Stsrship 😂 . You are lucky if that thing even makes it into orbit.
RIP fella😢
I have an idea to increase the life time or energy of INSIGHT with the current available resources in Mars
should have mount fiberglass brush under each edge of solar panel that self clean the solar array when fold and unfold.
or just simply use rotation brush wand that can be folded.
Not worth the extra mass and complexity. The arrays do not fold and unfold after the first time. Every gram wasted for things like that is every gram that cannot be used for science, which is the entire point of the mission. The lander was only intended to last 2 years so it's outlived the time they thought it had.
It is also an international mission, with instruments from around the world. Something NASA has a habit of not mentioning.
so dropping scoops of dirt is science?
@@bunnatang2081 Science is different from engineering. They didn't one day just decide "Hey let's dump some dirt" They had seen a similar effect on this lander and earlier landers and rovers.
@@ptonpc I don't think scooping dirt is a permanent solution for future mission. as they didnt expect that dust on Mars is too obvious than what they expected. For efficiency they will be back with good-old-brush soon, I bet that.
@@bunnatang2081 Again. The mission lasted longer than planned. With the limited mass they could land, it is not worth the extra engineering, complexity and added mass. How would you clean a brush for instance? The dust is not like on Earth, it's a 'stickier' due to static and its composition.
Every gram you use on the lander itself is a gram you cannot use on the science packages.
Why don't they just put a little brush on the robot arm to brush off the solar panels?
Or even make a smaller dedicated arm for that task?
Exactly. It's what killed earlier rovers too, so it was not unexpected.
As said above:
Dust is accounted in the mission specifications. The solar panels are designed to provide energy through it entire mission lifespan which InSight exceeded by 100%
Plus here some facts:
* Mars dust is charged so it sticks A LOT more than you might expect. Think about those little balls of polystyrene used to protect stuffs in the carboard boxes. Those freaking things stick to anything and are a PITA to get rid off.
* A duster would need some dedicated arm to clean the solar arrays, so this means mobiles parts and complex engineering meaning it can fails and perhaps damage the panels. Plus, remember the charged dust? This will clog the duster faster than the panels themselves.
* Every gram/ounce is dedicated to the mission. So having one arm dedicated to this sole purpose will add extra weight you wouldn't have for scientific instruments
*Keep in mind that NASA and JPL are on the side of the smartest engineers you can pick up anywhere, they design and almost casually land craft on a remote planet for DECADES. If you think about an idea how to solve [insert some issue you read/hear about here and there] they figured it out years ago and if that's not on the spacecraft, that's for a GOOD reason.
So yes, they knew this will happen even before designing the lander and they designed it knowing this will end the mission at some point. And they solved it the simple and most efficient way it was possible considering all factors, making bigger solar panels.
Listen to D C at your own risk. I took his arguments on in my comment, so I won't do it again here. But his side is worth debating and not falling for on a whim.
@@DC2022 Making bigger solar panels adds weight as well -- at some point, this crosses over with the weight of a feather duster attachment for the robot arm (even including the weight of an anti-static mechanism to unstick the dust).
A simple brush attachment would suffice. I use a broom on my solar panels to remove the pollen. The glass is very strong.
Studio work superb
just one question nasa why you did not put as a power source big piece of plutonium voyager 1 and 2 have these and they working decades
Интересно, а почему бы не использовать сжатый газ марсианской атмосферы для очистки солнечных панелей? Установить небольшой компрессор, баллон для газа (не слишком большого объема), выводные сопла прямо по центру солнечных панелей, направленные вдоль и наружу их. Допустим несколько марсианских дней набирать давление в баллоне, затем выпускать газ атмосферы через сопла, сдувая пыль.
Небольшой компрессор не потребует много энергии, уверен - у НАСА есть инженеры, способные это правильно расчитать, а не только татуировки себе делать.
It would much complicate the mission and the engineering.
Wondering if/when nasa will start putting a small air compressor and pinhole air ports across their solar arrays for Martian missions. Very light and easy solition
2:20 the only agency on earth which doesn't know how to clean dirt off glass
I would used wind and thermal shield bottom and instrument deployment arm to cleanup solar panels.
I'm sure the actual scientists and engineers who designed, built and operated Insight have already thought of that.
@@ptonpc they did and they're still following this with great interest. There are some paper available on the net on how they're gathering a huge amount of data about the power generation of the panels depending the winds, the amount of dust, even the shadows generated by dust devils! Thorough to the point I didn't considered.
Insight Lander: Will I Dream?
👏👏👏👏👏
Cant they just fold up the solar panels again and then unfold them to help clean some of the dust off
No. The ability to fold and unfold the panels would require more complex engineering and more parts to fail. That would make the lander heavier, which, considering the mass is limited by what they could safely land, would mean less mass could be devoted to the science payloads. Every gram added to the lander is a gram that cannot be used for science, which is the entire point of the mission. The lander was only intended to last 2 years so it's outlived the time they thought it had.
Why we can't fold the solar panel and unfold again so some dust might be removed
Precisely
You could call Ingenuity over for a dust removal mission...in about 5 years 😉
I still haven't understood how the trick of cleaning with more dirt works. Even after watching another video in which they attempted to explain it.
Imma clean my house and car with dirt to see the upcome. Wish me succes
The dusts on the solar panel are loosely attached so when you drops somthing on the solar panel it will vibrat and this vibration can help to remove loosely attached dusts from the solar panel, so insight used a bunch of dirt and dropped it on the panel that helped to remove most of the loosely attached dust on the panel this is a good idea but not a perfect one.
@@EXOPLANETnews Right but, wouldn't that have a net effect of making the solar panels dirtier, and therefore less clear surface area to absorb sunlight?
Maybe add a vibration capability to the solar panels. Dump dirt on them, then start the vibration: the heavier dirt will shove the dust around. After continued vibration everything will fall off. Alternatively, design the probe to do cartwheels and other acrobatics.
The wind catches the larger particles and is able to push them around, that helps push the dust off. Mars dirt is not like Earth dirt, it's finer but also electrically charged.
It's hard for me to believe that as hard as it is to land on mars and as expensive as it is there is no thought given to clean the panels off? Cmon, you have a robotic arm on it. Got to be a way to do it. Just a tiny brush on the arm could probably do it.
basically went to london without an umbrella
In the future couldn't they power a small turbine pump using residue retro rocket fuel to fill a compressed Mars air cylinder, and have the jets fan shape and in the centre of the panel? When the dust gets too thick just cover the camera lenses and press the button?
Yes, or simply add a dusting attachment. But nope.
No. And part of the reason why went into the design of the Ingenuity helicopter. The air on Mars is so much less dense than Earth, that any turbine or fan would have to spin up extremely fast. Plus, it would need to use the solar panels. Not to mention, if the blades are above the panels, it will block them. The amount of dust built up probably wouldn't cause too much of a problem on Earth, but the further you are from the Sun, exponentially the less energy is received. In other words, if you are twice the distance from Earth to the sun, you have only a quarter of the energy being received. 3 times the distance is 1/9 the energy.
@@ogshotglass9291 Interesting. I knew the air is 90 percent thinner, but thought that might make it easier to move the air with a fan, guess it's 180 of that. Cool enough.
So Mars is the same distance from earth as earth is from the sun? I didn't think it was near that far. Are you sure about that? That makes Mars further from us, than Venus or Mercury by a full AU.
@@TheRadioAteMyTV no, but the distance was an example of the physics behind the distribution of energy. Mars is actually at 1.5 AU from the sun, or 1.5× the distance from the Sun to Earth.
@@TheRadioAteMyTV If you were to go to Lowell Observatory, they have a path that shows the relative average distances of the planets, marked by metal disks in the concrete.
Tried cleaning home with dirt. Instructions unclear.
Mark my words: InSight will be back on enough power supply for the coming months, year even perhaps in the coming summer.
Because of the alignment with the sun and with the subsequent electrical storms this will likely cause, the extra dust in Mars' atmosphere will serve as its own duster for dusting off the solar panels.
This aged badly
We need to go back with a bigger and better Insight #gobackInsight2
Bigger? That thing weight two tons haha 😆
Someone contact Mark Watney to go clean the solar-panels.
Hello ❤😻
Why scientist didn't make that the robot could cleaning it self ?
Rest In Peace InSight
You can join your sisters, Spirit and Oppy in robot heaven now
How come there are Marsquakes but not tectonic plates? isn't it the sole reason for earthquakes here?
Mars crust is very different from earth. Earth one is very dense..
Mercury doesn't have plates but is contracting inward, creating their quakes. Quakes can also be caused by meteor hits, or ground collapsing, and even gas releases.
Idk i have never been

Why don't nasa use wipers on solar panel so that dust cannot accumulate
Indeed, allvery wonderful news & congratulations! SciencePhysicsMedicinePhysiology: a'l matters on a {asphyxicsubject} without samples; somewhat fortunate or un is another debate, can data be interpreted ie- can we oops it be put to productive use? Other than the time it will take too discern {Insights'} dataload
Hello 👋
Send perseverance helicopter 🚁 to fly on top of the lander sight. May be You could remove the dust on the panels.
Helicopter in space?
Mars the devon island paradise for geeks
💕
👏👏👏🇮🇶🙂💞
Did no-one think to install a dust brush on the end of its arm? Flip the arm over, dust off the panels, you're good to go. My tax money.....
You honestly can not be serious with this solar panel dust issue, that must be on purpose; it seems too obvious
its like going to london without an umbrella, who would have thought to make a car without windscreen wipers
there are very smart people working at nasa but still failed to make a robotic arm with a brush to clean the solar panels? did a another rover not died the same way?
NASA should have had more Insight.
It lasted longer than it was designed to.

Nice cgi. Btw is there a sun inside mars ?
No. A sun - inside a planet? No. 🙄
No. Why would there be?
Did you see the drawings ?
@@aychingao Those are drawings to illustrate a simplified version of the interior of Mars. Just because something has been coloured in yellow, doesn't mean that it's a star.
@@ptonpc Thank you for the patience you have to explain. Now I have another question, what are we looking for on mars that we don't have on earth ?
! 💝 💯 👏 🎉 🙏 🚀 👍 🤖 🎅 ✝ 🌝 !
Gettin dusty?
Gee.
we need more money so we can get more cgi to cheat people😂
How many units on Mars are now dead and dormant, because they were sent without any sort of windshield wipers to brush the dust off their solar panels?
Hey brainiacs, "It's getting dark and my batteries are low."
Did it really require a robot to tell us that?
Gosh, maybe you had better let NASA know what you figured out before the rocket scientists did! LOL!
Derp a little harder, Simple Simon...
@@codymoe4986 I just think since they invented ways of boring holes in rocks and taking detailed, close-up pictures of more little rocks 250 million miles away, then maybe someone could have figured out how to attach a little broom to a boom?
All that fancy equipment and no one thought to include a duster for the panels? Ok. So I guess dusting off things is still not rocket science. But they all knew it would happen, because it did to the other rovers.

@@DC2022 "entire mission lifespan which InSight exceeded by 100%" $$$$ Ever heard of under promise, over deliver? Yeah, those "geniuses" have too. Not EVER going to fall for that ratio.
"Mars dust is charged so it sticks A LOT more than you might expect. Think about those little balls of polystyrene used to protect stuffs in the carboard boxes. Those freaking things stick to anything and are a PITA to get rid off." $$$$$ And yet dumping dirt on it seemed to do the trick. So go figure. There is a way, and all the worry about damaging the panels by dumping dirt on it? Yeah, don't know what happened there.
"A duster would need some dedicated arm to clean the solar arrays, so this means mobiles parts and complex engineering meaning it can fails and perhaps damage the panels." $$$$ All mission require trade offs.

Space X has done just fine and on a microscopic budget by comparison with their geniuses. The arrogance of the statement is fighting words for those who know the repeated folly of man and MOST ESPECIALLY "experts". So again, I am not falling for that ratio either. Maybe an O-ring maker would buy into it, the ones who sell them to those geniuses who launch a doomed ship will. ETC. ETC. ETC.
Your excuses hold validity, but they also have holes as big as Jupiter in them that let's us see Uranus!
I agree. There are quite simple dust removal techniques they could implement, much more efficient than crude methods they tried with InSight, but it seems they almost enjoy struggling with dust accumulation rather than doing full science.
@@DC2022 No, duster would not need dedicated arm. It's XXI century already, and it's high time we stopped worrying about dust accumulation during primary or extended missions, and focused on doing full science instead.
@@BlisterHiker so since you're an expert, what are you proposing the JPL wouldn't have already though about it and ruled out. Impress us!
cgi 🤣
That how they spent bilion of the U.S tax payer money still have long before a man can Mars walk and then walk away.
