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.
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.
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...
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!
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.
Important distinction indeed. Rocks are defined by their mechanism of formation (i.e. their geological origin), while minerals are defined by their chemical composition.
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.
@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 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. :)
So inspiring. Just pictures of the surface of Mars like these were once only in my wildest dreams as a kid. I’m thankful I get to witness them in my lifetime
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.
"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.
The orbital conjunction communications blackout is definitely something to be addressed before people go to Mars. Fortunately, a workaround is entirely feasible, by placing data relay satellites at the leading and trailing Lagrange points of Earth, they'll be able to peek around the edge of the sun and maintain comms that would otherwise be blocked.
@@blacksage2375 it would cost more to relaunch satellites (Billions in USD) to the lagrange points of the earth of the sun when they eventually run out of fuel over and over, than to wait for two months with predetermined plans.
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.
Tbh, after knowing the existence of the black holes and gravitational waves nothing in space excites or surprises me except for those marvelous objects.
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.
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.
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.
I give this video a "thumbs up" for placing that blowup plastic 'alien', who was menacingly standing on the ridge. Because, we all know that this is what all aliens look like. 😞
Don't sell yourself short on your storytelling abilities. I was on the edge of my seat (actually, mattress...) when the rocks were stuck, then I was elated when you said that the solution was... ... ... *wiggle wiggle wiggle* I've never been so excited to hear and see a robot wiggling! Thank you for sharing.
How hard was to predict such problem as parts of the rocks or dust blocking the chamber? How hard was to install some small compressor to clean up the parts like that? Incompetence of some people in NASA is so stunning.......
Well good luck doing that. If it isn't there there is a reason, either impractical or too expensive. Mars' dust is statically charged, (too lazy to research) and is very hard to remove. You're not smarter than NASA.
@@FenrizNNN Impractical and too expensive....? Lets see: multi billion dollar, time consuming in project and planing mission is at risk of a failure because one small, light, reliable and cheap compressor is impractical and to expensive? OK..... Now, for the "too lazy to research" point about statically charged dust, do I need to remind you about those pictures of Rover solar panels completely cover in that "statically charged" dust and in the next period of time that dust was completely blown off by the Martian wind? Also, the problem in this special occasion was not "statically charged" dust, but the little rocks.....so lets try to solve that problem with risky maneuvers and shaking with huge time delay between Earth and Mars and hope for the best....if we fail, well my God....we spent just a few years and couple of billions of dollars on nothing just because one small "impractical and expensive" thing was too impractical for the conditions on one dusty planet.......
Tell me, Why do you think you're smarter or more important than other people? Narcissism? Retardness? Do you want to feel more special? You're not clever by not doing what everyone else is, we've already done that mistake and we learned. You won't.
Reasons we will never be able to live on Mars long term (not necessarily in order) 1) No air to speak of AND no Nitrogen for plant growth 2) since there is NO AIR (almost but not quite a vacuum) there is very little in the way of radiation shielding so any model that has rooms and greenhouses on the surface is a pipe dream 3) other than sending nuclear power plants there, no way to generate power, no wind, very very little solar, no geothermal 4) Not enough gravity (long term health problems will develop) 5) 3 month sandstorms Put an "earth lifeboat" 200 feet down at sea or 200 meters down in a salt mine and it would be 20x cheaper and 10x more sustainable.
To be strictly technical, Mars does have a weak atmosphere and weak winds. That's how those sandstorm are generated in part. The problem is that the light gasses like Oxygen and Nitrogen can't be held to the planet by Mars' weaker gravity. It's core is also very inactive, evident by the lack of geological movement, which is the reason there's no magnetic layer.
Imagine one day if they actually discover a huge water reservoir? You could then start sending modules out there before sending the people so that when they arrive they could set up a settlement. But man, what a hard life it would be until they built up some infrastructure
There is a solution to the solar conjunction problem and it will probably be implemented soon. Put a satellite in solar orbit designed so its able to relay signals from the Earth to Mars around the sun. This would however increase the lag. It will not be put in place until we are sending people.
Why don't they put solar panels on a spin cycle? If they get a coating of dust, spin the panels at high velocity to dislodge and remove at least some of the dust coating. I can't imagine it being highly complex to build such a mechanical system.
Another thing they could innovate to avoid rock blockages, is to collect the samples and hold them upside down, so the opening faces the sky, and insert them into the testing chambers from this orientation. This would guarantee everything that spills falls thanks to gravity and the locomotive jitters would dislodge any obstrucions.
The first HUMAN BUILT helicopter on Mars. There may have already been others, we don't know who might be out there. Rocks in the tube are why we need to send humans to Mars.
the spinning of Spirits wheels 2009 was unfortunate,but JPL changed my very nice S ^ P ^ I ^ K ^ E ^ D wheels for speed racer slicks Sojourner vs SPIRIT & OP ! Change my design,you lose.
The rock is too brittle to drill cause it's not bedrock, probably just a mix of rust and concrete from the cities that once stood there a long time ago.
@@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.)
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.
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....
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.
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.
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 👍👍👍👍
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
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).
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
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.
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.
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…🖖🖖🖖🖖🖖
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!
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.
@@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
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.
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.
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.)
