NASA's Insight mission has sent back some of the most amazing images and data of Mars ever collected. But this isn't the end...
In a new video, we're unveiling some of the final messages that the Insight mission sent to us. These messages might be the most important of them all.
Insight has sent back data about the internal structure of Mars, which could tell us more about the history of the planet. It's incredible data that will help us learn more about the history of Mars and Earth, and even ourselves! Watch the video to find out more.
seismometer, jpl, marsquake, insight mission, insight spacecraft
This mission was not lost as some have said here. It lasted twice as long as designed. The engineers traded power, weight, cost, evaluated risks and which ones to take and which ones to design against. I sat in dozens of meetings that traded off all the options versus the known data of dust devils in the landing areas, rock outcroppings and size of rocks in the landing area. This mission was a phenomenal success and provided data that will assist in not only future missions but to our understanding of the planet itself.
Was that at alula Saudi Arabia
This is the ONLY You Tube channel that I trust to tell me about space and the planets. No silly over dramatisation or speculation. Just sensibly told facts and chat about what is and isn't happening. These are easily worthy of showing on BBC next to David Attenborough.
And cartoon graphics.
Another is Matt lowne he has good weekly space updates
Cool Worlds is an honorable mention, although sometimes I feel the host goes off-topic once in awhile.
That's funny you put all this trust in a channel that click baits the titles of their videos harder than than prank channels lol
I recommend Scott Manley, Everyday Astronaut, PBS Space-time, Scishow Space and Anton Petrov also 👌
I can only shake my head in awe at NASA's achievements, and how it stretches an inch into a yard when it comes to extending missions.
More like a nanometer to pyramid of Giza
absolute madlads doing it for science
...and how they can stretch $1B to over $10B to make the JWST. Don't get me wrong, I am excited for it and look forward to everything we will learn from it, but I also look forward to a new truck every 60 months and I wouldn't be able to do it if the price I was expecting and the price I paid was 10x over. Just a critique of the bureaucracy, not the final product. I would venture to bet that Elon Musk could have built it for under $1B, bc that's what the free market is best at, and what the Federal Government excels at failing at.
Now if only we gave them a yard to stretch into a mile
@AllHopeAbandon...You would venture to guess that Elon Musk is an expert at building state of the art space telescopes?? LOL! Did he tweet that or did you literally pull that nugget from your own backside??
Good grief, but you Muskrats are gullible sheep...
I'm amazed that NASA scientists "hoped and prayed" that dust devils will take care of cleaning the solar panels. They thought of the arm with a scoop attached, but forgot to also attach a little brush at the end???
Well... even the best scientists are like children sometimes. :-)
mars dust is static-charged so it "sticks" to surfaces mainly the solar cells, the dust devils are also charged so when they blow on the rovers or at least close to them it picks up the dust.
mars stuff isn't the same as ours bc u know lack of atmosfore, mag-field and material composition.
That’s exactly what I thought. Dusty solar panels have always been a problem and they still don’t have a system to clean them, even though it literally kills missions.
Yep, a few extra ounces for a dust cleaner..... Too much to account for?! So let the rover die.
Astrum, Anton, SEA, Fraiser Cain, PBS Space Time are the pinackle of astronomy coverage on RUclips, can't thank you guys enough for your work.
Check out cool worlds too, an amazing channel from Dr Kipping at Columbia University
pinnacle
Cool worlds and John Godier as well!
You’ll like Curious Droid too, then.
Oh, and don’t forget Scott Manley!!
I love how short duration the official expectations are. They're like "it'll last 20 seconds... Omg it's survived for 69 years!"
I still can't understand why scientists didn't equip these rovers with little compressed air nozzles to alleviate the dust issue. Not like it was news Mars is dusty. Seems like a no brainer
Or a wind shield wiper, duh
Weight minimization perhaps
@@Casual414 that is quite literally the worst answer I have ever seen lmao
Weight issues is exactly the problem. Wipers will scratch the surface of the solar panels. Air nozzles would either need to carry far too much gas compressed, or a compressor which would use a hell of a lot of power. It really is not just that simple.
It's because compressed air expands and contracts in the tank according to elevation changes, atmospheric pressure etc. Meaning it would likely explode under the varying changes in atmospheric pressure leaving our atmosphere and entering the Martian atmosphere.
This has easily become my favorite channel. So many interesting things to learn from Alex.
He has the best photos, and latest information, plus his voice is so pleasant to listen to. This is the best space channel on all of RUclips.
Unquestionably the best - love his stuff and voice too
The BEST! When I am in charge of the remote, I haven't watched anything else on TV or RUclips since discovering this channel!
Nick, Believe in the Lord Jesus!
Yeah his good I first saw him on Joe Rogan.
I would have expected a possibility to re-fold and unfold the solar panels again to shake off some dust, or something alike. And I'm quite sure the design team also thought through some options of dust removal. I believe they traded the screws weight in for something they considered more valuable.
I have NO idea why they didn't include a "vibration sequence" (much like friggin' CATS, dogs, birds, and other animals) shake off water, dirt, dust, etc. It would NOT have been difficult. Vibration motors are inexpensive, and "resonate" throughout a device pretty easily. Cell phones "rumble", speakers rumble (although they move AIR). But it's obvious what I mean.
🐲✨🐲✨🐲✨
@@Novastar.SaberCombat the dust on mars is statically charged so it sticks to surfaces just like the regolith on the moon .. but NASA has Developed a new techonology to run tiny wires on the surface of stuff and apply a tiny voltage to loosen the charged particles .
@@Novastar.SaberCombat exactly what came to my mind!
You don’t have to guess. NASA have explained that they traded all other options for simply having bigger solar panels
@@Jono4174 bigger isn’t always better, in this case 😂 whats the point of having bigger panels when they are only running at 10% of their initial capacities?
I didn't put together at the time that it was this mission that got that read in the magnitude 5 quake. So, cool that this mission, like so many others outlasted it's planned end. It seems that the groups that design these types of craft tend to over engineer, but I'm not complaining.
This was a beautiful tribute to InSight. 🧡
Due to the thin atmosphere some kind of a blower might use up too much energy, but surely some form of rotating brush could have set up in the arm for a physical removal of dust from the panels. If you can fly a helicopter on Mars and do everything else, a rotating brush is going to be pretty low tech.
Seems like retractable solar panels would be able to just retract and then redeploy clean. But, barring that, it's hard to imagine why it couldn't simply tip the panels or rotate them completely upside down and then back up again.
@@BryceMillerE I think it was because of static electricity. Dust in Mars is very sticky because of that, and most of it wouldn't be able to fall from the panels by just flipping them.
I thought too that their decision to bet on the dust whirls was awfully optimistic. An alternative to brushing the solars would be vibrating them, with as low tech as just bolting a piezo speaker to the back of the panels. Rotate them a bit, ideally upside down and just bzzzz them free.
The downside with that would be potential material fatige, considering the whole thing is rather fragile to save weight. But maybe the next iteration will have something like that.
How about a little blower? Very low tech and no moving parts except for the motor. If it fails for some reason, you're back where we are now.
I'm disappointed though. No squeegee guys on Mars?
@@anonymike8280 Trouble is that the atmosphere is so thin. Mind you a toy helicopter can fly in it so maybe. Suppose they have to balance up energy saving, reliability and weight etc. Maybe brushing the dust would abrade the solar cells surface so increasing charge time. Whatever the solution its not rocket science. No pun intended.
It's strange that Mars may have a core that contains less iron than we might expect, while it's red rocks on the surface contain lots of iron
Not so strange! That's exactly why there is less iron in the core, it's on the surface. Earth had many sessions of mixing and melting, including the Mars sized Thea collision that made the Moon. Mars had little mixing due to major collisions, (Though it did have some mighty asteroid impacts.), after the initial consolidation and no plate tectonics.
@@fredwood1490 the the opposite might happen on a superearth -all the iron are in the core with heavy metals making them very metal free on the surface and maybe be just like IO with a silicon and sulfure landscape - I guess life would never get not space from those planets
@@jari2018 They likely wouldn't. Building materials aside, I remember hearing somewhere that if our gravity was about 50% stronger, then none of our current tech would have been able to reach escape velocity.
Insight lasted twice as long as intended, its still extremely impressive
Note to NASA: Include a robot arm holding a feather duster on future missions.
Doesn't help. The dust is static and can't be 'wiped' off easily... it clings to the panels and you'll end up just moving it around rather than removing it.
@@turtle2720 Sorry, but I've been to Mars with a feather duster, and I know it works. You just have to use the right sweeping technique rather than the back-and-forth flicking technique you use on Earth.
@@KarlBunker 😄
@@turtle2720 It doesn't "cling." Previous rovers had their solar panels cleaned off due to wind events and dust devils.
"however Insight's opponent was Mars, and Mars would not give up its secrets easily" aaa I love the blend of narrative and science on this channel, it always makes for a good story and a great learning experience!
Also seems to me that, even though these missions have been incredibly successful, future one should be focussed on longevity. Things like these quakes, over much longer periods, would be beneficial. Also, how about a really robust ‘breakdown’ rover, complete with tools to clean and repair other rovers. These ‘Work Horses’ could then support the creation of infrastructure for the future; thinking ahead
who repairs and cleans the rovers who clean and repair lol
@@euphoriamusic_ You send a couple so they can clean and repair each other. Their entire purpose being nothing but keeping the solar panels clean on the rovers they are assigned to.
@@Mr.Sequiro Great Idea, what about using fans, or some way to spin the Solar Cells to shake the Dust off...
The dust is also statically charged, which makes it a lot harder to clean with robots than you might realize. If there was such a simple solution, I'm sure somebody would have thought to include it by now. A true solution is probably much more nuanced.
@@dahZeee Ahh but remember dust devils have cleaned it before nearly all the dust off, so your theory holds no ground, a fan or some way to shake or spin the solar cells would still work, Remember it is usually the simplest Ideas that they forget pls remember that, Thnx for the input...
For the lack of a feather-duster, a rover was lost. For loss of a rover, data was lost. For loss of this data, a mission was lost. For loss of this mission, The Martians Invaded !! .All hail our new Martian Overlords .. :D
Thanks, Alex. I really appreciate the channel and videos.
Hearing those impact echoes was amazing too.
Well I've always thought they should have spent some time and effort into a dust removal system as it's always a problem for all the landers. For those landers that have arms, it would be pretty easy to pull out a brush out of a tool box, maybe even spin one on the rotary tool. Whatever the case I'm sure there's many ways to approach dust removal, from tilting panels and give them a shake to dusting them off.
Can't believe it was 4 years. It feels as if I've read about the problems with not being able to dig deeper only yesterday
Yepp. Time runs pretty fast😩 It seems like yesterday, when the mole failed.
I wonder if one day we'll actually be able to have LIVE video footage instead of just hundreds of pictures strung together
What do you call LIVE when a readio signal takes up to 20 minutes to travel from there? 🤣
What do you think video footage is if not hundreds of pictures strung together?
@@KeenanV 👍
I watch your channel before bed, your voice is very soothing and talking about space just gives me peace and makes me relaxed.
I seem to notice a trend where NASA missions seem to “aim low” but “achieve high”. They claim their newest project is only to last a couple years or so but then goes on to last twice as long. I’m pretty sure the Spirit rover was similar, where it was made for like, what, 90 Martian days, and yet it survived into the thousands?
That's the scientific approach: aim for something realistic, and everything you gain extra is a gift. Not like some billionaires who aim for infinity and can't admit the dust they're biting is terrestrial.
I love how you explain how they measure these findings and what doors gathering that information opens. I studied science in high school, but high school's been a while now lol
That was insightful.
I see what you did there...
crazy pun lmao i love it
Thank you for this beautifully delivered narration of what InSight helped us learn.
This is amazing to think about. Insight has shown us that Mars still has plenty of internal heat. That means free enrgy underneath the surface. A game changer when cost benefit studies are carried out. Makes the whole trip much more tempting to the business men out there.
Energy is there, sure, but we have that same energy source on Earth. It's not going to be any more economical to transmit that energy from Mars to Earth somehow. It's also not likely to be easier nor more economical anytime soon to utilize Mars' geothermal energy than it is to simply rely on either solar or nuclear energy.
@@GlitchCityPromo People are also forgetting there is no civilization on Mars, so not even calculating how much it'd cost to send everything there, there's alot of stuff that needs to get there, be assembled, not to mention food, water, oxygen,... It's simply never gonna happen. Just too expensive and no clear incentive why humans are necessary.
@@DarkAngelEU Agreed, We're getting pretty good at autonomous equipment.
@@DarkAngelEU there's also the insane value of the scientific knowledge that will be lost the moment a human sets foot on Mars. We'll never again know for certain whether any signs of life found there are from before contact or are contamination from us being there
@@GlitchCityPromo I don't think anyone ever has considered trying to transfer mass amounts of energy from planet to planet.
they could have put some brushes on the joints of the panels. by opening and closing the panels it would have wiped them cleaned
Nice reporting and very good graphics and presentation. I do have an idea that future mission managers might bear in mind: Supply a brush as one of the tools for the arm so that it can dust off the PV panels as needed. Thank you.
I'd like to hear EACH & EVERY Update of Space from your Beautiful Narration for the rest of my life
The exploration and better understanding of Mars is advancing slowly yet but luckyly, not stopping at all!
Good video. Random moment was when talking about effects of salt you used a footage from the highway in my city. I pass that yellow sign almost every day. Kind of weird to be in a Mars video. 🙃
Your videos are too valuable. Thank you
This is a most informative and enjoyable channel. Thank you.
This is basically a testament to human ingenuity at its finest.
A nice story - and solid piece of science - as usual with Astrum
A channel with such high quality videos that you always click 'like' before you even watch the video.
You doing a so great job with your videos. It is so fun and interessting to hear and look it.
Man, you really should create a Playlist with the songs u use in your videos background. They're so beautiful!
Great work Alex, as usual. Thank you. A question I thought bringing up before I forget: why even quakes happen on Mars, considering it does not have techtonic plates to begin with. Cheers
As far as we have understood today, scientists believe Mars quakes are a result of subterranean volcanic activity
After 4 billion years of existence there has to be some interior generation of heat. I am guessing that there are chemical reactions deep inside slowly causing nuclear disturbances and new elements to form that give off heat in the process.
I think the Mars Quakes are caused by the planet itself shrinking as it cools
Hindsight is always 20-20. Hopeing for a dust-devil cleanup was a reasonable risk to take. The robot still performed well above expectations. And they may not even have the budget to keep people in the Team to continue operating the robot. There's other missions, more science to be done.
There was a conspiracy theory some time back that someone or something was deliberately dusting off the solar panels. The urban legend that Humans have a covert base on Mars is still prevalent. Linda Moulton Howe's channel goes so far as to suggest that her secret insider sources have said Mars is a base for distant star missions from Earth which have and are taking place. She is a credible source btw.
( You're my favourite channel right now mate ... astronomy has been a breeze with these videos )
Excellent as always!
Have they tried using the thrust from the little drone to blow the dust off the panels? I know the air is thin up there but if it has flight capability it can still produce a lot of air movement.
The drone is very far away
Your videos always keep me looking up! Thanks for that 🙏🏻
I love Astrum, I wish I could contribute more to support this channel.
If only the solar panels could rotate and let the dust fall off, or there could be a brush like device on the arm. A fan would be lovely to blow the dust off, but I expect with the low pressure, it would have to be big and fast.
The atmospheric pressure has been fascinating me ever since I saw a video about the triple point of water which occurs at more or less the same pressure- about 6 mBars.
I love Alex's voice. It is beautiful, so calm, serene almost.
Great info as always, thank you. Science is what I like to breath in all the time and you fuel that for me.
You'll like Tony Fauci for he is "the science" 😆
So we can't even make a robot that survives Mars dust, yet people still claim we will go there in our lifetime...
It's because of weight restrictions that you can't have all the bells and whistles. If we could send people a rock sample mission would be far easier because a person doesn't have to wait hours for instructions on how to navigate around without getting stuck. Our biggest limitations are fuel and distance. You try building an rc car with multiple hour input delays and zero ability to repair or move when it gets stuck and see if you can get it around your neighborhood.
Thank you for your research
Thanks, insight team
Beautiful views of Mars after sundown in the eastern skies this month. Don't miss out on this rare opportunity.
A game changer would have been a small brush for the robotic arm
Wouldn't there be chance of it's getting clogged? making the "small brush" useless
Any exposed mechanism will be jammed.
It's been studied. It's not nearly that simple.
No much better solution is to rotate the solar panels upside down and cuz of gravity dust will fall and then after a while turn them back up simple solution.
InSight has given us so much insights about Mars
Brilliant, thank you.
Perhaps a brush fixed along the trailing edge of each solar sub-panel could be used to clean off the dust by periodically furling and unfurling the solar panels?
Risky... a fan or spinning brush is safer....
I always feel some connection with robots seeing and hearing about their "Final Message" always shatters me.
Awesome. Congrats 🍾🎈
Amazing content as usual, I will never cease to be amazed at pictures of the martian surface. How small we are and how little we really know about our world
At this point I'm sick of the dust issue being an issue. Given the cost of these missions one would think some sort of arm attachment would be sent along to facilitate the cleaning of the solar panels. Such an arm design and attachment wouldn't add that much weight and complexity. It just tells me that people haven't been tasked to address the issue. Time to resolve this issue for any future missions.
They refuse to employ non academics...
Apollo 11 etc was possible because they employed practical people....
Gotta love armchair scientists.
Would a static repulsion system help? They are going to be doing this in the spacesuites for the upcoming moon missions.
I was thanking the same thing!
Static repulsion is more a matter of static attraction. You end up with a dust collection grid that has to be cleaned - you are back where you started. No doubt the next lander will have a means of shedding dust, but it will be another system, another point of failure.
@@camcairns2584 you can reverse the charge so that it it repels it. The moon's dust is positively charged by the sun.
This is the way.
Well done! Thank you
Thanks bro!
Would it be possible, in theory, to arrange electrodes or magnets around the energy panels into a configuration which might create an electromagnetic field of some kind which would deflect the dust away? Or maybe just create a strong static field?
All they had to do was get another attachment for the arm which is a blowymatron fan it would have cleaned the heck out of it, and possibly turn it into a helicopter lol .... No need for a air compressor or some fancy tech.... Just a small blowymatron
@@goliathmb18 Yes! Maybe make it to where there are two (or more) arrays of solar panels. Which are each capable of dis attaching themselves from the main unit and taking turns flying themselves somewhere nearby where the sunlight is better. Then come back and re attach to the main unit to power it to do more drilling/analyzing.
@@buddygrimfield7954 hahahahaha, for real though i started to think about it more..... A blowymatron (delta fan) that has a small wind tunnel attached to it that narrows it down to a small nozzle that is then attached to a small flexible tubing that runs down the arm.... That delta fan should have enough power to produce a decent amount of airflow that should blow away the dust, but idk I ain't no expert, just some dude thinking why the heck did they not do something for the dust..... They are already paying millions of dollars on making it and on getting it to mars..... Atleast spend a bit more to make it last longer
Perhaps a small compressor and pump, connected to tubes that weave through the solar panel, like the veins in leaves, could periodically blow the dust away. Infrequent power drain to power, phased bursts so not all at once, and plastic construction would surely not increase the payload too much?
Or just raise the panels and give them the ability to flip upside down and vibrate slightly
or a brush on the arm :)
@@MrOverjay depending on the dust, brushing it away could cause scratching
it's statically charged dust, it clings to things a lot more than you would think.
@@burdeegirl no like......a brush, like a makeup soft brush.
These little robots and their teams have given us soo much.
Very good video!. thank you
Maybe this isn't a feasible idea, but what about being able to rotate the solar panels? They could be facing directly towards the sun throughout the whole day like a sunflower, and be able to flip or go perpendicular to the ground at night to let the dust fall off. NASA scientists are smarter than me, so maybe it's not an idea that would work
If you can THINK it, someone can BUILD it. Ideas are worth their weight in iridium!
If it does eventually get hit by a good dust devil, will it try to power up, or will the hardware have been destroyed by the elements and temperature in the intervening time?
Nobody will listen, to find out. Bandwidth to and from Mars is limited, so the channel Insight used, will be closed, to free bandwidth for other experiments.
Apparently, Mars has a layer of caliche like the deserts in Arizona and New Mexico. It's nearly impossible to penetrate even with backhoes, so that's why homes in these states are generally built slab-on-grade and rarely have basements. If the caliche _is_ disturbed the softer layers underneath are no longer protected and erosion becomes a problem. The Mole was simply not strong enough for the job.
Or dig next to the volcano lol
If it’s caliche-like, that would explain why a wash wouldn’t work to clean the panels. That would just turn the dust into cement, destroying the panels.
A fan on top of the panels and the solor array being able to tilt 90 degrees should take care of the dust issue.
It truly is amazing regarding the little OVERsights that someone like a NASA scientist would look past without thinking about. Literally a simple wiper like device that would take the most little of power to operate would've been able to "extend" InSight mission much further past the 4 years they were able to.
I was literally just coming to the comment section to say that
It's been thought of. Many times. It really isn't as simple as it sounds.
A bristle brush would have been a no go as it would have also damaged the solar arrays. The only thing that would have worked would have been some kind of spray nozzle for compressed gasses. To make that work they would have needed to add some kind of system to compress the Marian Atmosphere, all those components would have added weight and complexity to the robot arm. Plus the arm is too short in it's current form to reach the entirety of the arrays adding even further weight. Another option might have been to make the arrays double sided and include a mechanism to turn the arrays over and shake the dust off, again more weight. Considering the original engineering goal was for 2 years you can't really fault the engineers for not including some means of cleaning the arrays.
A fan.
@@acarrillo8277 money isn't an issue, having a sapphire coating on the panels wouldn't be too big an issue no?
Honestly, how hard/expensive would it be to put a brush or fan on there? Seems like the robotic arm didn't do much else than put the instruments on the ground
What great engineering. 👏👏👏
Remember one mission they did they became nervous the river would loose power because of dust covering the panel. A wind storm can through and actually blew the dust off and was able to charge back up
I am beginning to expect these missions to last longer than expected.
NASA should add a small package to their next visit to mars and drop it at the Insight location. The package could include a simple charging station and another copter that could fly over the Insight solar panels and use it's jet wash to blow the magnetic dust off the panels so it can recharge.
Or... get this... they should have built a tiny brush onto the side of the robotic arm, so that they could brush off the panels periodically.
I was actually thinking there might be a plan in formation to send an engineering drone there. One that can apply simple solutions and extend the lives and functionality of equipment that is already there. Not too far fetched and, considering the cost of getting things there, recapitalizing at the same time. 🤷🏽♂️
this stuff is facinating.
So perhaps future missions should use radio-isotope power, or cleaning systems for the solar panels. Regarding your sponsor who's gone all-in with Rome's Laudato Si, I counter with;
Feed the planet! Free the carbon!
iv never understood why its never occured to any of the spacecraft engineers to include some kind of sweeper to clear the dust off of the solar panels, lmao..it would probably not be much more complicated than a windshield wiper mechanism found on cars, or even simply some kind of compressed air device to blow off the dust..it would be something real simple that could considerably extend the life of solar powered craft on the martian surface
Weight is the main issue, it’s simply not practical to have canisters of compressed gas on it.
@@Swampsong117 i was thinking along the lines of a small compressor, and the tank could be constructed from lightweight carbon fiber, and wouldnt need to be that robust, just enough to hold 100 to 200 psi..although i feel some kind of sweeper would be more practical
Like Alex said the scientist thought that the whirl winds would keep it clean. Now they know it doesn't work. Next time they'll have a way to fix the problem.
It seems to me that fine dust is hard to blow off and could scratch anything it is pushed over.
You think they never once thought of this? Let me guess...you haven't even tried to actually look into the topic huh.
They really should have made them so they can retract and clean it self off that way
Or even just shake
Fascinating Mars!
really enjoyable video cool :) hay just wondering. say in a year after its off then a strong wind comes along and somehow blows it all off, would it start working again or would the cold have totally destroyed it?
Destroyed.
Our planet is returning to its pre ice age temperature why are so many not asking the question ' what temperature should our planet be?
Why wouldn't they add some type of wipers for the solar panels knowing the sand will eventually be the death of the instrument.
Most likely money and weight
Exactly!!! Why wouldnt they do that?
The mechanism will jam with the amount of sand dust with additional sharpness.
They need windshield wipers for the panels so that way they don't have to worry about running out of air or even having to bring air canisters and just rely on power
My name is Wren so whenever I hear someone say “thank you to wren for sponsoring this video” I always think “you’re welcome”
How about a brush that spins that clears off the dust? Attachments NASA!!
8:55 Hello from Slovenia :)
I'm just not ready for this. I can't lose another trooper on mars. Not again.
DAMN YOU RED DEVIL
Damn this thing landed back in 2018?!? I clearly remember following the mission and it's landing. Seems like it was only a couple years ago.
2018 is only a couple of years ago
@@Brother_frojd Thanks for letting me know!
I also like the bit about WREN
Makes me wonder if some sort of a vibratory mechanism would have helped with the dust situation. Low amplitude, high frequency vibrations should be able to shake the dust off from time to time as long as the surface is slightly tilted. It might cause other issues to the sensitive instruments in the long run though. What do I know, I’m just a mechanical engineer. 🤓
They should start sending duster drones along in future missions, I would assume it could hover a couple seconds when needed and dock with the rover/equipment for charging? Maybe?
For some unknown reason power and longevity are always a dispoable issue with them.Carl Sagen almost had to beg the team to use the last bit of maneuverable power to turn the Voyager space craft around for one last shot of our planet earth before it left the solar system. Because of his insistence we got the famous blue dot photo.
I would suggest small vibrators attached to each solar disc as well as a tiny tilt of the disc shape. That should make it possible to easily shake of the dust from time to time!
This makes me appreciate mother Earth even more. 😃
Mission is over goodbye in sight thx for all works🤖
It would be nice if we had some links to the previous InSight videos from your channel
Hi Alex! Thank you for another great video! Would you be open to extending the length of your videos to say 25-30+ minutes? I can't get enough of your content! ❤️
