mars update mars 2022 gusev olivine mars odyssey
Nothing brings me more joy than rooting for a small car-sized robot that we (humans) made and sent millions of miles away to an unknown world. They're just robots, but it's so easy to humanize them when 1. We (humans) made them and 2. We're all working together to achieve something truly incredible. Thank you guys for producing this series! I'm so excited for the next installment!
Edited to clarify that I am not an engineer nor do I work for NASA. I used "we" as a collective term for the human species.
its an extended tentacle of yet more to come plunder, exploitation and colonialism by the powers that should not be. one can only hope humans never get off this unfortunate rock
This is truly the ultimate form of taxpayer dollars. I know not much funding goes into NASA. But... Damn if I don't love what they do with the mere pennies they likely get from my tax deductions. If they put more funding into space and education I think I'd be so happy to put money into their programs.
:)
@@stagdragon3978 Plus… we (that is, the wealthy folks who run everything) get a good return on investment of tax dollars since technological innovations turn into profit-making opportunities here on Earth.
The helicopter might be a better option long term but the solar panel design needs to be improved
I'll never get over how crazy it is that's there's a helicopter on Mars.
Ditto
Wait till you hear about most humans thinking they are inherently good, gonna blow yer socks off
I wonder when we will get a jet ski over there?
I know rìght?
Absolutely! There's so little atmosphere to support flight. The thing had to be made out of lightest carbon composites. The speed of sound is even lower on Mars than on Earth, and you don't want blades go anywhere near supersonic. At the max design rotation rate of 2900 rpm = 48 rps, the tip of the blade moves at 0.75 Martian Mach. And look how big the blade airfoils are! This makes the coaxial counter-rotating rotors even less efficient, because of the larger overlap, but they had to trade a bit of efficiency for compactness. And still, the lift is so small, I'm really surprised it can lift its motor, battery and camera-dense things you won't make of carbon fiber or styrofoam no matter what-for 15 min of flight on end. Marvelously bizarre!
So, essentially, Perseverance had the robot equivalent of having a pebble in your shoe.
Or eye 🤣🤣🤣🤣
@@terrafirma9328 the eye version would be a rock in the camera.
@@koharumi1 Okay, so maybe a fly stuck in your teeth ?.... Or, a piece of steak stuck in your throat. Or a chipped tooth, broken filling. Or....just...rocks in your head.(an American expression.)
Something stuck between its teeth, then?
@@mathmusicandlooks 😬😬😬😬😬🤣🤣🤣🤣
It's amazing that a river used to run near that volcanic area. Imagining what it looked like in all it's glory makes my mind fantasize double time.
It's my personal theory Mars was Eden. The Apple was the Atom. Hence why Mars us covered in a radioactive isotope that is only known to be produced during an atomic ignition..... We ruined Eden. Then we either transplanted or were transplanted. We of all creatures do not have circadian rhythm that fits Earth. Neither does it fit Mars, but if you account for slowing of planets and dividing the difference it appears to fit.
Many scientists will say off record,abd few in record...it appears our dna was modified and not natural evolution.
Perhaps we were slaves once...
Or perhaps we we're gods once...
Perplexing and thought provoking nevertheless....
Billions of years ago, Earth and Mars both had rivers. However Mars is too small and no longer has useful air or any water.
I have to admit, I feel a sense of regret and sadness when I think of Mars. It once had water, possibly rivers and lakes . It could have had life. If things had been just a bit different we could have had a sister planet with life of it’s own. We could have had Martians.
@@mikoto7693 you can watch cartoons.
@@mikoto7693 It would have been pretty incredible if life had evolved on Earth and Mars at the same time.
Im glad NASA knows how to walk their rovers so that they wont get eaten by those giant sand worms. Also the cameramen taking the pictures of the rovers on mars do an incredible job.
Double true! ;)
I hope their search for Spice is successful, that those core samples finally reveal some.
@@spacewolfcub if there were spice it is surely already mined out by the Pykes
Imagine just how operating blind scientists are really working on mars with communication relay time.
Stanley Kubrick was the director. Oh, and he didn’t really die in 1999. That was just a cover story so he could start training for the Mars mission. And Paul is dead.
Imagine just flying a drone only on the drones cam. Then add a minutes delay. The work and genius going into those missions is STAGGERING. What a feat of talent and dedication.
The drone is controlled by artificial intelligence like a Tesla car only better (hopefully lol). The really amazing thing is the rover transmits it all up to a Mars Satellite with a considerably higher power transmitter or talking to Perseverance would be like dial up on top of the six to twenty minutes signal lag depending on planetary positions. Satellites save a lot of space on the rover for other instruments besides a powerful transmitter.
@@MountainFisher Thx for the details! I knew it is AI controlled (also awesome), but i meant that you have no real way of correcting errors due to the signal delay. That must be nerve wrecking sometimes for the guys on earth, but they have to confident in their work. I hope they are proud!
@@deadralynx1288 I worked in aerospace starting in the 70s and the care put into just a satellite is astounding. Our tolerances were cut down so a simple bar that was plus or minus .010 inch (yes the shuttles were based on the inch) would be .003 or hand fitted with no tolerance to speak of. People wondered why they cost so much.
@@MountainFisher "Why they cost so much" ... The tech benefits of the space age are MRI and countless other technology that we take for granted now. The money we spend on fusion and space are a JOKE compared to weapons and playing power games with foreign politics. This makes me so angry, as you can clearly see how far we have come with the titan probe for example. Wild tangent here ;) - i recently rewatched apollo 13 and how that whole space mission was nothing but EXCEPTIONAL humans and calculations on PAPER to bring people to the moon. Someone said NASA's whole computing power was that of a 2005 flip phone. We have to reach for the stars or stay and fade into the cosmic night.
@@MountainFisher ....
Would you explain what you mean by "tolerance"?
This is way more tense than anything Hollywood can come up with. Pure brilliance!
@@sirensynapse5603 I agree with you.
Brilliance.
It'll be a movie one day. Probably called Stowaway.
Nah, since the movie would last about two months, it would be extremely boring. I bet half the audience would have run out of popcorn and left by the end of the first week...
@@Quickened1 I don't disagree with you.
everytime i see his videos about the mars rover mission. I am still amazed that there are human made robots that traveling on the surface of another planet doing their things, its truly inspiring
Alex,
Olivine is a mineral, not a rock. This is an important distinction, because the rock in question was likely basalt, which often has large phenocrysts of olivine in it, and a defining whole-rock atomic makeup. Even calling a mineral olivine can be considered somewhat inaccurate because olivine is really two different minerals, called forsterite and ferrite. The composition of these minerals and the different structures they form tells us so much about the crystallization environment.
"They're rocks, Hank!"
"Jesus Marie, they're minerals! How many times do I gotta tell you?!"
Ok Hank
I prefer extra virgin olivine in cooking. Cold pressed.
Important distinction indeed. Rocks are defined by their mechanism of formation (i.e. their geological origin), while minerals are defined by their chemical composition.
You seem to know your minerals. I suppose olivine is igneous. Is olivine a semiprecious stone? Are you a geologist or rock hound?
I am stunned to learn that after all these rover missions and with all the many talented people on these projects, nobody has yet thought to put a cleaning brush arm or equivalent device on a Mars rover !
Especially after the solar panel failures of past missions I know this rover doesn't use them but them amount of accumulation should be an obvious problem by now
Mars is quite an amazing place. While I am more fascinated with other planets, Mars is proving a goldmine for the advancement of advanced robotics, and the sample return will fill me with glee, not to mention a manned mission later in life. I REALLY hope all goes well!
I'm of two minds about a manned mission. The robots are already so advanced, and certainly beat humans in resilience in such a harsh environment. These robotic explorers roam the Martian surface for years on end. A manned mission would take a year to get there, and another to get back, in a high-rad environment. And people... you know, they eat all the time to stay alive, and quite a lot! Even with a space-tailored diet, 4-5 times the body weight per year. An average US food consumption by weight is about 12 times the body weight a year; you can reduce that below ×4 but the food will be disgusting, and astronauts would have to endure it for years. It would be an achievement to chalk up in the end, no question here, but... to what end, besides the very getting man on Mars? They'd do their sciencing with the same tools the robots already do. In your mind, what is that what humans could do on Mars that the robotic explorers cannot? I'm drawing a blank, as much as I want to think of something useful.
@@cykkm think of it as 'baby steps' vis a vis the colonisation of space.
@Cy "kkm" K'Nelson In hours they could do what takes months for the rovers, no need for a lag to take a decision, a human cna manipulate more easily and quickly the objects, they could explore faster and better as well. They can repair broken tools if needed, clean up too, one person would be able to do alot, so I imagine that a small team would be quite productive.
As Attila Juhasz said before me, there's also the colony angle that will be observed with this mission.
We could get some neat video recordings, audio and even have an idea of how the place smells, at least for those who will be going. They also will have the privilege of being the first humans on another planet.
@@cykkm This is a VERY common thing I hear btw, and tbf it has some merit in the short-term, although imo a Creation has never truly surpassed its Creator in every way. People will need to leave the planet for some reason or another. If they don't need to, they will anyway because that's who we are. So long as it's done safely and with as less waste as feasible, it's a worthwhile venture for NASA and the private sector to do.
@@dylangtech It's hard to disagree, and, personally, I think this is what defines us, the humans. I can only quote Robert Sapolsky: “It strikes me as one of the most irrational, nutty, magnificent things we are capable of as a species: the more something cannot be, the more we have to make sure it is… The more clearly, irrefutably and arguably it's the case that you cannot make a difference, the more that must be the motivation to make a difference.” This is why I said I were of two minds about this. We have to do that, but today's technology is so feeble for such an endeavor. Are we ready to commit to such a project? How long will it take?
Perhaps, with a firm commitment (meaning funding, of course), we can do it in 35-50 years. We can't pull such a feat with today's technology; we'll have to bet on the technology that will be developed for it. Can we hold on to it for such a long time, given the project will slip on the schedule many times, due to this uncertainty? It's a generation's project.
Now, let's look at two currently active government-funded projects.
JWST took 25 years from proposal to launch, and was nearly canceled-twice. Realistically, its cost and allotment for the next 5y, total $10B, is negligible compared to the US military budget; using $500B as DoD's average slice of the pizza in these 25+5 years, it's 0.07% in comparison. And we the people could hardly tolerate this expense, and that's for non-reasons, such as a momentary political gain. Will we stick to something at the very least 10-20 times more expensive for twice as many years? When the politics gets into the scientific and technological game, this is where I'm getting rather doubtful.
So, enter the SLS (a.k.a Senate Launch System), which consumed $25B in 10 years already, and will be ready at teeny-tiny $4B+ per launch exactly by the time that figure will be ROTFL-high, assuming the SpaceX's Starship project won't hit an unlikely serious snag. And this thing gets a non-stop financing at nearly 10 times the yearly rate the JWST got. It won't be for nothing, certainly some new tech will come out of it, but it's certainly not rolling toward a thundering success...
The comparison is discombobulating. Are we even _rational_ enough to keep our irrational, against-all-odds commitments? I only know we ought to be, but in fact am carefully pessimistic about it. Kinda sad.
The precision in these scientists' actions is amazing!
I think it's because every single step and movement is planned. It took them a full month to actually do something that seemed seamless and straightforward in this video.
Just so fortunate to live in a lifetime where I can see footage of this amazing planet
As a mechanical designer the very moment I saw the pebbles I knew why this was sucha big deal. You can see there's very particular mechanical locking mechanisms near those points. In fact on closer inspection you can see scratch marks. that's like having a rock in cogs oh dear.
Dust is so fine on Mars, and so ubiquitous, one o
Would have to be resigned to the fact it is eventually going to get into every part of the rover.
If only they had built the flying drone with a high pressure air sprayer gun that they could use to circle around it during slow times and blast it clean.
.... Or, "Cleaner".
If I had my way, they would have included a third auxiliary rover just to clean the other two, and maybe make some simple repairs.
@@TheNoiseySpectator Good idea and hey; maybe little drone buddy "can" fly over rover and blow it off. I dunno. We lost that other one cause it got covered in a storm and couldn't charge. Maybe.
@Shasta Trinity They void them well and the rover is only a few years comparing to ours. its not aging and the weather on mars is far more in Conflict with ours and helps the rover also ? strange not much happened as of when or yet it might be more Closer than we may think.
I wonder if they have considered putting a radio repeater/booster spacecraft in a suitable location to allow for uninterrupted communication? As the number of missions increase this could be useful.
I've heard of a few proposals. I think SpaceX drew up plans for "MarsLink" but these haven't been funded yet. If I'm not mistaken, the best approach is to have comms sats stationed in orbits around Sun-Earth, or Mars-Earth Lagrange points (or both).
Good plan
we cannot leave the earth. space is not real.
The Internet cannot exist without satellites in space. So go outside since space, and ergo the Internet, doesn't exist, as you say
@@luisostasuc8135 99% of communication happens via terrestrial and undersea cables
This video was just amazing, Astrum! I had no idea that happened with the rover and you not only showcased it beautifully but it felt kinda epic!
Olivine is a mineral, not a rock. Rocks are composed of minerals. Olivine is one of the most common minerals in the rock type basalt. Basalt is very common on Mars and Earth
Calm down, Hank
Calm down, Hank
Olivine crystals can also be found in meteorites, which makes me wonder if that sample is entirely native to Mars (I hope it is, though)
The presence of Olivine everywhere indicates a period of time of strong volcanism where most, if not all, Mar's water was mineralized.
A volcano on any planet can likely spit out a rock into space that could travel to another planet, so don't get too excited. Samples need to be taken from various spread out locations to determine how widespread it might be on Mars.
Yes, I find it incredible the wonderful guys from Nasa managed to move around this affair around in Mars helped by a little drone to find the safest path. Almost ruined the mission by a few pebbles that couldn't engage the sampling machine! Luckily it was all sorted by rolling around! What luck but also lot of kudos to the people of the Nasa, no wonder they went ape when it was working again 👍👍👍👍
That's just Algerian Sahara...
We are living in amazing times, helicopter on mars, humanity back to moon and much more. That’s simply amazing times.
With your pleasant to the ear voice and perfect inflections, you would make an excellent audio book narrator! I'd love to hear you read the book Dune.
Can't believe the engineers never thought that rocks would crumble and get stuck in the loading mechanism.
I'm pretty sure, they thought about a million things that could go wrong. That was a 1 million and one. To see that they could even overcome that is a testament of ingenuity.
Engineering note to future NASA builders. Add a on board mini air compressor the robot can use to blow off dust😉
@@terrafirma9328 it will add to the weight and be quite situatational and run out of gas, its always a comprimize. I would advice some nimble and strong robot tools/fingers that can do some cleaning and maintainance
Dealing with dust, dirt. rocks, and distance, making it so you could dump it out, should have been, a given. even if they never used it.
@Shasta Trinity We got spatulaaaas
And thats all!
My Desert.

I think the most impressive part about all these solutions is that they're so simple. People naturally want to make things more complicated. Sometimes a little shake will solve a big problem.
My boyfriend and I LOVE your channel. You have such a pleasant voice, and a genuine interest and enthusiasm for what you talk about, making things super interesting! You really have a gift of explaining and talking. We also recommend you to our friends and get stoked when we meet new people who also watches your content.
I read a comment further down here saying you have a perfect voice for storytelling, and I agree. Would love to hear you read sci-fi books like Dune.
Keep up the great work, your channel is an absolute treasure.
Can you do videos/ video series about the Viking lander (the first object to land on mars) and the Pioneer spacecrafts. I think they are underrated spacecrafts that have very interesting stories!
Hearing the audio of the helicopter on Mars is something I’ll never forget.
The Jezero in Bosnia and Herzegovina, after which this crater on Mars is named, is beautiful! A total contrast - beautiful hills and mountains, full of water, hiking trails and rivers. Heaven on earth. :)
I really appreciate this content; thanks for bringing us the story of Perseverance as it is being written.
Such incredible stories impeccably told.
A very good job making an otherwise dry subject suspenseful and entertaining as well as informative. Bravo.
They way u r connecting it with dune …. Fabulous… spellbound
I've been binge watching all the videos on this channel...
Definitely my favorite channel..
U explain things so eloquently..👌💞
I never understand that these situations don't have broom 🧹 attachments, air hose blowers, so it could clean itself off from dust and debris especially since it's in the environment it is and it can clean off it's solar panels. Idk how there isn't a attachment of this nature...
Broom would scratch instruments
There are no solar panels. It's nuclear
@@crazywileycoyote there is air
The dust is electrostaticly charged. The rover is equipped with systems to remove dust but they are not 100% effective.
They are not designed and not expected to last this long. So the broom and air blowers is not a consideration in the design.
I love your storytelling skills .. it made this small adventure magical .. I am amazed by how much I learn .. while having fun too :)
I love that they scratched their heads for 2 weeks and then all they had to do was drive around a bit to dislodge the rubble.
This whole series continues to amaze me. Everyday. I'm still trying to realize it for real.
Amazing video, thanks for sharing this with us….I love how the little rover is doing such a good job in trying to get samples done. Sometimes I think it could use a little brush of sorts to help clear up the dust which accumulates upon its surface, that is if it doesn’t get hidden elsewhere when it is being brushed away. It can happen if not done properly or by mistake. HIGH 5…🖖🖖🖖🖖🖖
I was expecting them to use the helicopter to blow out the pebbles as a last resort. Might blow more pebbles or dust in but better than the mission ending! Glad to see they had a simpler and more sensible solution.
The air on Mars is 1/100th Earth surface pressure... EXTREMELY thin, so "blowing out anything" with such thin air is next to impossible. Later! OL J R :)
I was fortunate enough to watch the launch. Amazing mission!
Great video. So amazing to see what the human ingenuity is capable of. Thanks for presenting.
Man do i love this rover it Almost feels like it has its own mind!
You tell the stories of these amazing rovers so well. Really love this channel!
Why? it´s just click bait topics with misleading names.. For example this video is called "Perseverance's Most Unexpected Discovery on Mars" But there was no discovery what so ever.

Utterly brilliant, thank you.
i avoided all other channels discussion on the JW telescope images because i was waiting for you to make a video on it since it was your channel i first heard about its launch all those months ago but it never happened. Also as a Dune fan that intro was awesome. Great video as always.
It's coming. I wanted a nice selection of images to talk about before I made the video. You're very kind to have waited this long though, I wasn't expecting people to do that.
Bless the Maker and His water!
Channels like yours are what make my life happy every time I watch them I hope you earn a good living from this because you do a fantastic job and I'm sure it takes a lot of time and effort
You tell these stories so well
Thumbs up for the Dune reference alone!
The Roman Empire was one of the most technologically advanced civilizations of antiquity, with some of the more advanced concepts and inventions forgotten during the turbulent eras of Late Antiquity and the early Middle Ages. In later years long after the fall of the Roman Empire people would look upon these massive structures like the colosseum or the aqueducts and couldn’t help but think life was more advanced in the past. My grandson was looking through an old book of mine. The book showed pictures of the moon landing, along with supersonic aircrafts such as the Concorde. I had to explain that before I was born humans had gone to the moon. Didn’t return since 1972. We also had jets that could travel faster than they travel now. The last Concorde flight was 2003. That’s almost 20 years. Ironically, he then asked why was life more advanced in the past then it is now? Did these things really happen he asked? It’s easy for us as humans to get stuck as far as progression goes. We need to keep moving forward and keep progressing. Not going backwards.
Before we decided to spend ourselves into oblivion on war... OL J R :)
The Romans came up with concrete with which modern civilization would be hard pressed to do without.
But yet humanity does regress at times as we see so often in the timeline of civilization and can only theorize has happened in times even farther back in our past. It’s part of the endless circle of time. What has come before will come again.What goes
around will come around. Progress is not a continuum like space and is not even a constant but more an erratic series of jumps and false starts in which life span is not a factor.
Other factors come to play in technology such as feasibility, economics, need, etc.
I needed all of it to be put in context, very good.
I have to say that this was an exceptionally well tod tale. Thanks!
Imagine if that broken and dropped core had a fossil in it.
Amazing ! Perseverance and Ingenuity ... Who named those robots ? SO spot on ! 😀
They had a contest.
Preseverence was named by Alexander Mather a middle-schooler from Burke, VA.
Ingenuity was named via contest by Vaneeza Rupani, a high schooler from Tuscaloosa, AL.

Thanks for turning something that would usually sound boring into a story of heroism
And people quote it as "The Pen is Mightier than the Sword"....looks like it was a pebble after all. XD
Thank you Astrum for sharing this news.
Also geothermal activity is a VERY good sign with these sorts of things. It is one of the building blocks of life oddly enough.
Alex, your videos are fantastic - from research to illustrations to narration!
yoo
Very good work. I'm really impressed with what have been done so far. Let's keep moving and occupy Mars.
Such an absolute marvel of science, technology and luck that we can see this. It is out of this World!
Great video, but there's some confusion here about the geological terms "rock" and "mineral." This video incorrectly calls olivine a rock. An example of a rock with a lot of olivine in it would be something like peridotite. The concept of "high mineral count rocks" (7:44) makes no sense since all rocks are made entirely out of minerals (alright, modulo groundmass and amorphous stuff). You might be confusing the way the word "mineral" is used in geology with the very different use of "mineral" in nutrition or agriculture. It's true that igneous rocks could provide material that's favorable for life for various reasons but one simple way to think about it is that they are brand new rocks with chemical potential hasn't been used up by weathering yet. Check out Bowen's reaction series. (I have a geochemistry PhD and am an MSL rover planner.)
They're minerals. Jesus Marie!
Next time they should take food and just leave it in the middle of nowhere and see if any ants or animals will show and eat it.
Now there's an idea🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
If anything it will be roachlike or ratlike or some form of tardigrades
Corn chips.
@@terrafirma9328 I will love to see what those look like
Awesome, good work!
when i was a young man I used to make Fasteners (screws) ...I made millions and millions of them....I tell ya it would have been a real honor to make the screws that put this machine together thats roaming all over Mars !!!
I bet it would. If only private citizens could contribute their own parts to such projects. 😏
But, space rovers have to be not just very rough, but *REALLY, REALLY, VERY TOUGH!*
Every last part has to be built _especially_ for each rover to withstand the stress of where it will be going, down to the camera pieces, circuit boards, screws and even the tires.
Excellent video as always (algorithm bump) the best Herbert novel about living in a harsh environment was called Whipping Star and has many fascinating bio-tech ideas.
It's a big assumption that even microbial life is not on mars under the surface. The orbital signal interruption is something I had not thought about. Thanks for that. Great story well told. That's why we need human explorers on mars.
You can't have human explorers on mars if you want to find life. As soon as humans land on mars we have no clue if life came from mars or from the earth. Due to the bacteria and microorganisms that live in the human body.
10:15 now our robotos poop!! 😅
Jokes aside though, can we take a second to appreciate and respect at the fact that we are looking at and talking about fantastic pieces of machinery millions of kilometers away from us? Sure it may seem analogue compared to star trek but this is truly breathtakingly amazing!!!!
thank you for an amazing update.
So due to perspective of earthly experiences NASA assumed all rocks are hard. The Earth is very unique in planetary terms and what we see as normal is likely very abnormal in the rest of the universe particularly our moon's size and it's effects have created such a unique environment on Earth.
Nothing is "very" unique. The word means "like no other". A thing can't be VERY "like no other", nor MORE "like no other". It either is, or is not.
"So due to perspective of earthly experiences NASA assumed all rocks are hard."
nope. we know earth rocks can age and become brittle over time as well.
"The Earth is very unique "
Now THERE'S an assumption.
There is a saying in my country (Turkey): "Don't let a stone touch your foot." So i say "Don't let a stone touch your wheels Perseverance! Thanks Alex for such video.
Is there a reason for the saying?
@@Lemone_99 It's like wishing good luck in a different way.
The NASA guys jumping around when the pebbles dropped out was juvenile.
If you were there, and you were not so moved and elated to the same level, then you ... Should have...
Then, you would not have worked your way up to being there in the first place. People like these and projects like this are _fueled_ by such passion and excitement and love for this!
.... But, yes, that was pretty undignified of him. 🙁
Could I just say, despite Mars being barren and rocky over basically the entire planet, there’s something about it that is just gorgeous. Maybe it’s just because it is somewhere beyond where I will ever see but I find it so pretty.
The verse from “Dune” really got me dreaming about the rover crossing the red deserts of Mars, very nice touch :)
This is fascinating... i am already rooting for the nimble and flighty Ingenuity while Perseverance ambles along. Can't help but humanize them.
On future exploratory missions I wld assume as great strides are being made that an AI robot with independent dexterity functions might be included.
you had my curiosity with the title, but with an opening quote like that you have my full attention
It makes me so happy that Ingenuity is still relevant
You hyped me up there in the beginning by referencing Dune. This past year I keep finding references to it. I even bought the full series in a single book. I haven't read much more than a few pages of it. But every single time I hear someone reference to it. The thing that they proceed to talk about is always something I'm really interested in. Which is why I'm convinced that I will love the book... when I eventually get to reading it.
It might be easier to digest in individual books. Its also not nessesary to finish all of the books because Frank Herbert died before he finished the series and the last two books are really a different (unfinished) story set in the same universe. Of the first 4 books, the first two are about one character, and the second two are about his son. And the first book really is unique in the series, nothing else really like it at all.
Why doesn't NASAand ESA place each one solar power satelite at the L4 and L 5 positions 30 degrees ahead and behind Earth;s orbit to act as relay stations for communication with all the craft around and on Mars? Ir would add lag to the signal travel time but remove the conjuction signal blockage.
How come we don't triple our budget on every project to make it slightly better?
Maybe having done it with James Webb will spark an idea that makes such a relay a decent use of NASA's poverty budget but until there's actual people there constant communication with Mars isn't strictly necessarily.
For a long term rover mission its more of an inconvenience. As you rather note its still not like we command these things in real time. Indeed the average lag is I believe around 20 minutes each way which is more then enough to rule out a lot of time critical responses, never mind knowing what to do correctly once you hear the problem. If something is going to keep for a few days while NASA brainstorms what to do... it will keep for a few more to implement the solution.
Wasn't expecting the Dune intro! Awesome
Man I love a good Dune quote
I’d argue the craziest thing found is weird piece of string caught in the drill chuck. Check out MarsGuy for awesome weekly updates on the little robot
Awesome. I wonder what date are these samples supposed to be back on earth?
Hum... never?
FedEx maybe can help?
@@martinlatvian5538 you mean Spacex 😎
2035 - if all works out, it will be complicated ... pick them up, send them up to an orbiter, ship them back to earth and land them safely.
@@danihz5610 Oh, yeah! SpaceX can and they will.
Fun fact - Jezero means "Lake" in many Slavic languages.
This is an excellent vlog with comments on the reasoning and the actions taken by this rover, 👍👏👏👏👏
it's funny to me that they didn't immediately think "let's drive forward then slam on the brakes" to dislodge the rocks.
It's moves at .01 mph 🤣
Lol It's funnier you think that
To solve the communication issues they could put in orbit around Venus a repeater communication satellite. Venus orbit is faster and will be in position to link up during the solar blockade. Or maybe in orbit around the sun 🤔
Soon they will have to find ways to link up for constant contact with Mars.
Put a repeater satellite in the position of the Earth-Sun Lagrange points, L4 or L5, which is at the point of a triangle intersecting Earth's orbit around the Sun, with the Earth and Sun at the other two points of the equilateral triangle. IOW one point is ahead of us in Earth's orbit around the Sun, the other is behind us in our solar orbit. It would be far enough away from Earth to be able to maintain a radio link between Mars and Earth when the Sun is in between us. Later! OL J R :)
This is so incredible!!
Wow, Perseverance got its sample collector jammed on my birthday. That’s wild!
Wow
I've always thought it odd that these rovers don't have a brush of some kind as one of the attachments for the robot arm.
How easy it would be to sweep dust off the solar panels, or stones from the collection tube with a simply brush.
Needs charged gas of some type. To burst where cleaning is required...
Or a small can of pressurized nitrogen!
A lot of government programs are encouraged to spend money and not to be efficient. They already had a rover die because it couldn't clean its own solar panels.
@@zualapips1638 NASA accounted for opportunity to gather dust, which meant that they wanted for opportunity to only last 1 Earth year. They received eight instead, which would be a win in my books. A rover relying on a broom, or gas to clean off its panels would be an extra point of failure, which is why curiosity and perseverence is nuclear powered.

Exactly
Thank you so much for not labeling your video as NASA's horrible discovery, frightening situation or some other stuff like a lot of other channels do you try and sensationalize their videos.
"We must walk without rhythm." I had to look at the video title again because I immediately recognized it was from Dune.
