It's hardly a sign of maturity to send billion dollar probes after any shiny object passing planet earth. Most likely, there's not much to see anyway. There will be others.
@@dan8910100 Indeed you can't. At least the scientific community gets it. Common goals and the pursuit of knowledge, no matter where you're from or what your personal believes are, working together towards a goal. Seems like the best place to start no matter what the obstacle. Cheers.
@@SimonWoodburyForget No, I'm not saying that at all. We're talking about this specific case. And why scientists are having a hard time deciding whether this would potentially be worth the effort or not. Now some schmuck with a keyboard comes along and claims humanity collectively needs to grow up. Because regardless of how clueless he was about the subject before he watched this video, said schmuck is now in favor of sending a probe on this mission, so maybe his children might find out that Omuamua was only an oblong shiny rock. Or even worse, we invest in the probe, send it and it becomes obsolete before it has completed it's mission. There are tons of interesting scientific projects to pour money over. The trick is to decide which ones has a chance of rendering some measure of success for humanity. My vote would be on preparing a probe for the next shiny rock that comes along instead of trying to chase the old one down. Also I don't particularly contribute to hours of wasted productivity. That's not my style at all.
Sounds like we need some robust plans for generic but well rounded probes that can be "quickly" assembled and sent out... you know... several types of them for these purposes. That way when we get a surprise like that, we can get it together and send it out... but that's a lot of work, like you mentioned, without a destination...
Yeah, this is the kind of thing that's much more convenient when you have 'patrol' probes already perched in an orbit where they can pick up a lot of speed in a variety of directions on short notice... but it's a BIG ask getting someone to spend their budget on a probe designed to wait around for its entire lifespan HOPING a valid target passes by years after launch, HOPING it will be on a trajectory the probe is equipped to intercept, and HOPING the probe still works correctly when/if its chance comes.
@@05Matz Yes!! Yes!! Let's enter the realm of Star Wars or Star Trek and remote probes being launched. While we're at it, let's just go ahead and build a Death Star. Complete with shuttle craft, a planet killing laser system and whatever else it had. More nonsense proposals to gather data that doesn't get you anywhere or do much for you other than gathering that data and what it is. Yes. Spend billions upon billions. We have to!! It's a must! Top priority! If we don't know what it is or where it came from, it will be the end of humans forever!! Patrol probes. Lol. So laughable and ridiculous. You guys absolutely just luuuuuuuv living in fantasy lands and trying to Star Trek/Star Wars to reality.
When the flyby happened, especially when the object accelerated, I remembered a story (Pirx's Tale) from Stanislaw Lem, where Pilot Pirx, on a scrappy space hauler with a dysfunctional crew (part ill, part stoned, part drunken) detects a huge spaceship, possibly millions of years old, crossing his path at hyperbolic speed. Everything he tries to record the encounter, or to transmit coordinates, fails due to malfunctioning instruments and unavailable crew, and the alien ship is passing by undetected and unnoticed by anyone except him.
@@MichaelWinter-ss6lx Yes!! Prof. Corcoran and his VR-barrels (I think every barrel contains one person), or the Futurological Congress with the "maskon" drugs 😀The latter is stunning, as a very sad and harsh reality is totally superimposed by multiple layers of drug-induced sugarcoating.
I immediately thought of this! It would be hard to pick **the** best Pirx story, but this one is definitely among the best ones (alongside Terminus and Ananke, I would say).
Leaving a comment here in case, by any chance, any mission is launched towards it. I probably won't be alive when it reaches it, so good luck and I hope it was worth it o7
We need to rebuild our economy around space, not build space around the economy. People always worry about the cost of missions, thinking of it like a pile of cash we're burning. But that money goes to people and businesses. If we spend 5 billion dollars on a space mission, that's 5 billion straight into the economy. That money goes to the engineering companies and their employees, and in turn it goes into other sectors of the economy that those companies rely on like transportation and fabrication, and down the line it goes. What we should be doing is we should be shoveling all the money we can into our interstellar endeavors, and let the rest of the economy pivot to pick up and live off the stream of wealth that it generates. If we did that, then the kind of advancements we'd be able to make would be unbounded. We could launch missions on a whim without delay. Think about it.
SpaceX is headed that way. Making space profitable by Starlink and other means. Once we get to the moon, start mining it for rare earth resources. Makes solar power much cheaper to produce. Plus, you don't need to worry about pollution if you do it on the moon! Mine asteroids. So. Much. Resources.
I mean we could just stop sending money to Ukraine and other countries that have demonstrated it's not helping them, then start sharing data with SpaceX (because that's literally the only company we have that's actually capable of spaceflight) in the condition that other companies would also be able to get that data to start their own programs too. Treat space infrastructure as an investment and make it make money. Them it'll take care of itself
My only issue is with human greed. A tree does not refuse to fall because it wants more value for doing so. A house cannot ask for more money for its existence, people do. Vehicles cannot decide to not operate when fuel prices rise, people do. When will it "top out"? When is enough enough?
@LadyAdakStillStands a tree refuses to fall because it's existence depends on it. Let's not get into the evolutionary/biological parallels with economics because it will be a very long conversation. Houses are built and owned by people, they aren't alive and don't act at all. This is apples to oranges. The entire premise of economics is that wants are infinite and that resources are limited. It's a model that has been applied successfully for most of human history. Without greed, human progression stagnates. Greed comes with the drive for growth and exploration that has gotten us where we are. Does it need to be balanced against other things? Absolutely. But it's still necessary
The idea of planting trees under whose shade we’ll never sit encourages us to think beyond ourselves, focusing on the kind of world we want to leave behind. Whether it’s through kindness, hard work, or leaving something enduring for the next generation, it’s a powerful call to make our actions count.
No. Any putative 9th planet would be way too far out ( >100 A.U.) to have any significant effect on objects in the inner solar system. Only something like a star could do that and there's only one in our solar system.
it didn't speed up as it left, but it slowed down less than it should have. many people believe it was speeding up due to the term 'acceleration' describing it's change in velocity, but in physics unlike in everyday speech, acceleration only means force being applied to change an object's movement, not necessarily speeding that object up
The way I see it, the effort is never wasted: we would gain SOME knowledge in the doing of the tasks necessary, we could potentially gain knowledge during the flight (the craft WOULD pass by and through several regions of the solar system that we've not studied much), and then we'd gain knowledge "at" the target object. This all holds true for Project Lyra and the Comet Interceptor, and just about every other mission that the space science folks can come up with. None of them are fools, they would pack as much science into any given trip as possible. And honestly? Catching up to THAT thing in just over 20 years? That's pretty damn good. It's just so difficult to really grasp the distances involved for us "lay people" as it were, there truly isn't anything on Earth that gives us even a hint of astronomical scale. But as you rightly point out, politics (not so much economics actually) is going to be the problem, as it always has been for space research. Governments are just like corporations in this much: they only get excited when you tell them they're going to make a lot of money off a given venture.
Space exploration is always economically viable. People get paid to design, build, and manage those missions. The money isn't loaded into the spacecraft and launched into the void. No matter who profits the money stays here on earth, in the economy.
Worth doing. The expense is not going to be in launching the probe, it's going to be monitoring it all that time. Still, worth it. It's not like it won't collect data as it goes out. Also, we're in an era of drastically dropping prices for mass to orbit. Lots of these "yeah, but we'd have to have something huge, so no" missions will start to become at least a consideration. Falcon Heavy didn't initially fly much because nobody designed a probe that needed the lift capacity. Now they are and New Glenn, Vulcan, Terran R, and Astra's rocket 4 ... Oh, and Starship ... will allow people to go even bigger. Bigger or more often. Both are good. Anyway, Eventually we'll send a probe and eventually the labor cost to monitor the probe will be more of a consideration than the cost of the probe or the initial launch. That's going to open up a lot of possibilities.
I’ve worked on a number of long-term deep space missions. Operations costs can be substantial, but I have never seen greater than 50% of the cost of development, and that does not include the launch. Missions that hibernate, such as Pluto or Dawn, have significantly lower operations cost, although sometimes resurrecting the knowledge gained by the last group of operators can be daunting and challenging.
Have to give a shout out to the Initiative of Instellar Studies at 5.39, if you check there webpage they have in house artists, one of them is David A Hardy, who is 88 years old! in 1954 at the age of 18 he became an illustrator for a book by Patrick Moore!!! wow, any Sky at Night vitage fans? that takes you back eh?!

@@OlivierMosimann Well, you have to keep in mind its an Australian movie, so i don't think its a bad watch all things considered. It was certainly different than the usual Hollywood-style alien invasion😁
I don't know if you think you were being clever with this comment, but it's absolutely vapid. Yes, the thing that caught their eye did happen to be shiny. It did not catch their eye because it was shiny. It caught their eye because of the astonishing things that it was doing and it's unordinary shape. The fact that it was 10 times shinier was taken into account but no scientists did not get distracted by a shiny object.
I think it's a better bet to keep an eye out of for objects like this and time a mission where a probe could intercept it rather than chase it. It has been done with comets already with great results.
Data that in the end isn't much use to the average person. Nor does it solve any problems here on Earth. It's all just another way to spend billions upon billions of dollars because as they always say (like you do), "we have to find out" or "we have to know". Because god forbid we don't know what it actually is, where it came from, etc. Oh the horror!! Yes, let's allocate $10 Billion right now for a mission so that all the engineers and scientists at NASA can justify their salaries.
It is a huge asteriod and a piece of the debris field of Tiamat, the 1st planet to cross Earth as a part of our Sun's binary solar system..Carlos Munoz' Ferrada's Herculobus..
The locale is paradise, the natives are insane tribal primates too busy murdering poisoning the planet and killing each other over imaginary lines, tribal symbols, and two thousand year old parables and allegories to get anything done.
Another consideration is communication with the probe at the rendezvous distance. There are ways to achieve low bitrate communication at that distance, but no ground network that currently exists could support this mission. Significant investment in ground infrastructure would be necessary.
Chemical rockets don't have enough power, but we have options. Nuclear electric would be helpful, mainly to decelerate over years as it approaches. Nuclear thermal if you're impatient.
To me it would be best to research more into locating further objects like that, a capacity we lack today. Instead of chasing one object for 30 years, it sounds more sensible to prepare to find more of them. I am pretty sure we get many similar visitors every year.
Thanks for another excellent video Alex. In my opinion, chasing Oumuamua would be a great waste of time and money. However, for any new and similar type object in the future that might be worth pursuing, the Solar Oberth Manoeuvre would be the best method for such a mission. But you neglected to mention that - after executing the manoeuvre - the heavy heat-shield could then be ejected, opposite to the flight vector and effectively act as extra reaction mass, thereby further increasing the craft’s Delta-v. Additionally, after ejecting the heat-shield, and at a sufficient safe distance from the Sun, a Solar Sail could be unfurled, which would also considerably increase the acceleration of the spacecraft. Many thanks and All the Best. Paul Conti, Wales (UK).
Thank you for this vid! I don't understand UA-cam. I have been subbed for years, but the last video that came into my feed was ONE YEAR ago. I completely forgot about this channel unfortunately. But today YT decided to bring it back under my attention again, hooray!
Astrum, I had to chuckle when I noticed that, at 1:09, you decided against trying to pronounce Haleakala. Just for the record, (Mt.) Haleakala Observatory (and National Park) = hah-lay-AH-kah-lah (Hawaiian for ‘house of the sun’; 2nd. syllable often Anglicized to ‘lee’; located on Maui).
The appearance of Oumuamua may be a lost opportunity. However, we're in a "historical curve" in regard to our technological evolution in regard to occurrences like this. We've known for decades, in regard to astronomical science, that these kinds of events occur (see, just for example, the general concept as vividly displayed in the fictional novel "Rendezvous With Rama" by Arthur C. Clarke, decades ago, though in that story such occurrence was far more significant in import) - and Oumuamua simply happens to be the first time in history of actually seeing it. There's also the case of Comet 2I/Borisov, which was observed not long after Oumuamua. Those of us alive today would love to pursue Oumuamua, as discussed in the video here. But, of course, humanity could also just PREPARE, and be ready for the next time - even though we have no idea when that "next time" will happen. Technological development/evolution is going to continue, and in the future, humans involved in such kind of space exploration may be much better situated to take advantage of this kind of "random" event to launch an exploratory mission. So even if we don't do anything about Oumuamua itself, that shouldn't affect humans on Earth from being better situated to exploit such opportunities for engaging in this kind of exploration missions in the future.
If it were an alien probe that is programmed to go star to star. Possibly the change in direction was the computer course correcting the gravity assist of our sun to go to the next star on its list. Do we know the next star it would reach on its current path vs if it had not changed?
There’s a deep fulfillment in knowing we’re part of something that extends beyond our lifetime. Watching efforts like these reminds us of the quiet but profound power in actions that benefit others-even if we’ll never see the final outcome.
@ The funny thing about being a survivor is that while we can only speculate and hypothesize why things happen to us you already know everything for a fact, don’t you?
The acceleration and trajectory are very peculiar. Also they said it was covered with space dust, expected on something travelling through deep space. Yet, it was still 10 times more shiny than a comet. This taken together with its unusual shape, you have to say there is a significant possibility this wasn't natural.
An object like Oumuamua passes through our system about once per year. This particular object was only visible for a couple months before it was too far away for any of our telescopes. The LSST is projected to identify up to 70 of these objects per year. I swear this is the same type of math I'm hit with by used car salesmen.
The fact that it accelerated like that is rather interesting. I wonder what could have made that happen. I feel It’s totally worth it. SpaceX and all can sponsor a rocket too. Could be good long term marketing. But it’s definitely one of the closest interstellar objects we’ll ever get by a mile(pun not intended).
@@biomerlreminds me of an origin from the game Stellaris, a planet in your solar system was destroyed, and the xenophobic faction of your empire thinks it was an attack and decides to retreat on the other planet of your binary system *Turns out they were right*
Even though I love space stuff (I’m here afterall) I couldn’t think of a worse way to spend research money than chasing that thing. Heck, if the trajectory we observed was SO far off our expectation, what are the odds that trend doesn’t continue, and, it’s now nowhere near where we expect?
I think it might might be a metal piece with some unknown molecular bandage , probably a left over of an explosion . Its trajectory amd the angle of its journey really made us think all these but it’s not an alien sent object or shape that is meant of long interstellar journey or can generate power of its own .
Just to be clear: NO! No, there is NO OTHER WAY to alleviate our curiosity as to whether we can catch up to Oumuamua EXCEPT trying to actually catch it. Go Humans!
I think hitching rides on celestial objects with lots of power options for ongoing data retreival and images from wherever it goes would be amazing.. Turning it them all into observitories
Maybe by the launch window, they will be able to use something like the EmDrive or some other propellantless propulsion to slow it down. Would be ideal since you'll have practically unlimited deltaV with no weight penalty, but it will be limited to very low thrust-to-weight ratio. It will have plenty of time to slow down while it approaches since this propulsion would be entirely electric.
Elongated, cigar shape, a kilometer long, shiny, changes it's trajectory without any visible means of propulsion. I don't wanna sound like a conspiracy theories, but I think that's an alien spaceship.
Have always thought alien craft would be made from rock and stone, the stuff lasts for millions of years. Some rock even has magnetic and thermal properties.
Why not? The U.S. military talked about manufacturing aircraft carriers out of icebergs, or an ice and sawdust composite, during WWII. The idea was abandoned, not as impractical, but as of limited utility due to such a vessel’s operating area being limited to the Arctic. Had we gotten an earlier start, they could have been immensely useful as a virtually unsinkable airbase with which to protect convoys in the North Atlantic.
@@richardletaw4068 it was the brits not the americans look up project habakkuk, it also was shelved due to impracticality since they were already in the process of building better carriers
@@richardletaw4068 It was a British project and it was abandoned exactly because it was impractical. It was to operate in the mid-Atlantic in temperate waters, which pykrete (the ice-sawdust composite) is capable of withstanding. The issue was that you could build several conventional aircraft carriers with the amount of steel needed for a refrigeration facility large enough to produce the pykrete in a reasonable timeframe. I think in the context of space travel rock could be an effective and extremely cheap method of shielding against radiation, the problem is it's quite heavy so may only really be useful for space stations that don't need to worry about payload capacity and fuel efficiency etc.
I'm sorry to hear this. I'm 27 and though to myself "I'll only be 50ish when we reach it". I can imagine the sadness of missing out. Fear not, God is with you. Also, there is plenty to learn in the rest of the time you have on earth
I love the way he says we only noticed it 40 days after…. At &7 km a second…. So what happens when something much bigger and faster comes hurtling towards….. wait…. what’s…. crash, bang, wallop. Feels safe to know we have a ‘late’ warning system 🤣
Thank goodness im not the sharpest tool in the box because we would still be without the wheel if I was. Im staggered just what is now possible thanks to a lot of very clever people.
3rd trajectory option - Build Freeman Dysons Orion drive, and set a direct intercept. It would easily catch up in a few years. It's a travesty Project Orion was never continued and built, at the very least as a form of emergency asteroid impactor defense.. A missed opportunity, but it's never too late.
Took a month to notice it, by then it was passed and long gone. No chance to notice anything coming our way heh, considering we about to re-enter the galactic dense disk, i`d say this was just the 1st of many in the following many many years. Who knows how many more we might have missed..
Chasing Oumuamua seems like a waste of time, resources, and money. I would suggest that rather than going after Oumuamua, we work on being better able to detect interstellar objects before they reach the Solar system so they can be studied. We didn't detect Oumuamua before it was already on it's way out.
Well, first of all it will help us develop better tech, and second This is our version of cathedrals, we need a grand spectacle every once in a while, we need to do things to show that we can do it, because we are humans, we want to be more
So you want to miss a chance in a millennium? Oumuamua could potentially be an alien spacecraft or something completely unknown. Even if it's just a rock, it's from a solar system that is alien to us.
@@Lone_Star86 The video states it is traveling quite quickly. We would have to build a probe in record time, sling shot it around several planets, and then HOPE it catches up with Oumuamua. No. Let's consider Oumuamua as a lesson that we need to improve our tech to locate interstellar objects better. Let this fish go and build a better pole to catch the next one.
Please launch the mission guys. we must KNOW! Isnt it strange that it used a similar manuever to fall to the Sun to get a boost out of our solar system just like the proposed missions route? To chase it? ...duuude what if that is a craft or probe from another stellar society
Just because we've never seen an object like this doesn't mean the Universe isn't full of them.Wake me up when the next one actually stops for a Coffee...
could we catch up to it? possibly, it would be a major risk with a very VERY high reward if so. but is it worth the money it would cost to do so. no and i'll explain why, the composite of oumuamua is going to be nearly the exact same as the asteroids we would see here. the composition would be nearly identical to terrestrial asteroids. it would be mostly water ice with some possible methane, and some other slightly harder elements that help it to make its form. again its a big risk with a big reward if we do but we already have a good understanding of what its likely made of. its just the specifics is all we are really wanting to know.
And that in the end doesn't help us in any way, shape or form. Not a single person can rationally explain why following it, studying it and knowing about it is relevant or worthwhile. All anybody says is "for humanity" and somehow we have to know all about it just because. But it doesn't change a dam thing here on earth or in anyone's life in any relevant way.
Its 19,342,228,920.68 kilometres away from earth now... approximately... working on exactly 7 years. This will NOT happen.... it's apparently travelling at 87 kilometres per second, not the 26 you said.
I would assume that people behind Project Lyra study were somewhat competent in estimating that it would be very hard but we probably could at the very least go by. Although aside from the mentioned issues including costs and political will there is also quite possibly delaying/cancelling other missions (Dragonfly could be one of them since it also needs some precious plutonium) and there really isn't much time to the mentioned launch windows.
@@ImieNazwiskoOK The thing is, yes, it's moving away (at about 6 AU per year) but it's going to be out there for centuries and there are plenty of repeating launch windows, which is why I say we (humanity) will send something there sooner or later.
Presumably the actual position of oumuamua was tracked for a long time and used to derive the anomalous acceleration. Is there a relationship between that acceleration and distance from the sun? Perhaps even an inverse square law suggesting the acceleration was caused by solar radiation somehow? If so then Occam's Razor implies that it's a natural phenomenon. Otherwise there is indeed a mystery. Sounds like an obvious question and I'm sure people are going to say that scientists have already thought of that. But all I've heard is that there was an anomaly. I've never seen a function of that anomaly plotted against time or solar distance. It would be very interesting to see that.
important to note that although oumuamua was subjected to an acceleration, it didn't actually speed up the object, it just kept oumuamua from slowing down quite as much as it should have. acceleration in terms of physics doesn't always mean a net gain of speed.
@ Thanks for that - makes sense. Apparently the Marco Micheli 2018 paper determined that the measured acceleration vector always pointed approximately radially from the sun. This to me suggests a natural phenomenon even though the precise mechanism is unknown, ie no outgassing observed.
@@sbrown314 if i recall, a prevailing but conjectural theory is that it is largely composed of nitrogen ice, which would not only be volatile enough for the push, but wouldn't leave a visible coma
The video only deals with how to gain enough velocity to catch up with Oumuamua. It raises the question of how to spot it and how to slow down with no gravity assist possibilities. Perhaps the probe could use radar to detect the mystery object.
By the time we get to it, it would be so far away from the light of the sun, and so dark that it would make it next to impossible to observe it in anything but infrared color, if it is still emitting heat
If we haven't detected another one yet, how NASA knows they are all similar to oumuamua an how common they are? The interesting thing about Oumuamua is that no one has been able to classify it, it neither a comet or a asteroid or come up with a possible reason why it accelerated out of our solar system that fit the data. We don't yet know if other objects of this nature will do the same thing.
maybe I didn't listen to the video very well but To catch up with Oumuamua, we must take into account that the Earth and the object are moving simultaneously. The speed of 'Oumuamua: 87.5 km/s The speed of the hypothetical probe: 70 km/s. Since we are trying to reach an object that is moving faster than the probe, it would be impossible to catch up with it under these conditions. With a relative speed of 17.5 km/s in favor of Oumuamua, the distance between the probe and Oumuamua would increase by 1,512,000 kilometers per day. This means that at a speed of 70 km/s, the probe would never be able to catch up with it and would move further and further away from it.
9:09 I find it absolutely fascinating that we have machines like this. Pluto was discovered with a blink comparator a mere hundred years ago. The next hundred years?
Imagine we build a probe that sling shots around Jupiter & the sun, catches up to Omuamua, slows down to match speed, & Omuamua activates a warp drive/hyper drive and zips away. 🤯 a few billion dollars used for 2 secs of data but proof of advance alien life. Worth every penny.

I just hope that humanity can collectively grow up so incredible projects like the ones mentioned can actually take place.
It's hardly a sign of maturity to send billion dollar probes after any shiny object passing planet earth. Most likely, there's not much to see anyway. There will be others.
We never evolved to exist as one single tribe. You cant socially engineer "growing up".
@@dan8910100 Indeed you can't. At least the scientific community gets it. Common goals and the pursuit of knowledge, no matter where you're from or what your personal believes are, working together towards a goal. Seems like the best place to start no matter what the obstacle. Cheers.
Tell that to the talmud creatures
@@SimonWoodburyForget No, I'm not saying that at all. We're talking about this specific case. And why scientists are having a hard time deciding whether this would potentially be worth the effort or not.
Now some schmuck with a keyboard comes along and claims humanity collectively needs to grow up. Because regardless of how clueless he was about the subject before he watched this video, said schmuck is now in favor of sending a probe on this mission, so maybe his children might find out that Omuamua was only an oblong shiny rock. Or even worse, we invest in the probe, send it and it becomes obsolete before it has completed it's mission. There are tons of interesting scientific projects to pour money over. The trick is to decide which ones has a chance of rendering some measure of success for humanity. My vote would be on preparing a probe for the next shiny rock that comes along instead of trying to chase the old one down. Also I don't particularly contribute to hours of wasted productivity. That's not my style at all.

"Hows that for a slice of fried gold?"

🎵“Don’t Stop Me Now!” 🎵
Sounds like we need some robust plans for generic but well rounded probes that can be "quickly" assembled and sent out... you know... several types of them for these purposes. That way when we get a surprise like that, we can get it together and send it out... but that's a lot of work, like you mentioned, without a destination...
Yeah, this is the kind of thing that's much more convenient when you have 'patrol' probes already perched in an orbit where they can pick up a lot of speed in a variety of directions on short notice... but it's a BIG ask getting someone to spend their budget on a probe designed to wait around for its entire lifespan HOPING a valid target passes by years after launch, HOPING it will be on a trajectory the probe is equipped to intercept, and HOPING the probe still works correctly when/if its chance comes.
@@05Matz Yes!! Yes!! Let's enter the realm of Star Wars or Star Trek and remote probes being launched. While we're at it, let's just go ahead and build a Death Star. Complete with shuttle craft, a planet killing laser system and whatever else it had.

@@05Matz ESA is currently planning a mission like that, called "Comet Interceptor"
When the flyby happened, especially when the object accelerated, I remembered a story (Pirx's Tale) from Stanislaw Lem, where Pilot Pirx, on a scrappy space hauler with a dysfunctional crew (part ill, part stoned, part drunken) detects a huge spaceship, possibly millions of years old, crossing his path at hyperbolic speed. Everything he tries to record the encounter, or to transmit coordinates, fails due to malfunctioning instruments and unavailable crew, and the alien ship is passing by undetected and unnoticed by anyone except him.
Seems I missed that one. I love Lem's style;• sad that he's not so well known in America. After all, he was the inventor of Virtual Reality!

@@VadimKudim That's the expectations... and it's also the boring option!
We need to rebuild our economy around space, not build space around the economy. People always worry about the cost of missions, thinking of it like a pile of cash we're burning. But that money goes to people and businesses. If we spend 5 billion dollars on a space mission, that's 5 billion straight into the economy. That money goes to the engineering companies and their employees, and in turn it goes into other sectors of the economy that those companies rely on like transportation and fabrication, and down the line it goes. What we should be doing is we should be shoveling all the money we can into our interstellar endeavors, and let the rest of the economy pivot to pick up and live off the stream of wealth that it generates. If we did that, then the kind of advancements we'd be able to make would be unbounded. We could launch missions on a whim without delay. Think about it.
SpaceX is headed that way.
Making space profitable by Starlink and other means.
Once we get to the moon, start mining it for rare earth resources. Makes solar power much cheaper to produce. Plus, you don't need to worry about pollution if you do it on the moon!
Mine asteroids.
So. Much. Resources.
I mean we could just stop sending money to Ukraine and other countries that have demonstrated it's not helping them, then start sharing data with SpaceX (because that's literally the only company we have that's actually capable of spaceflight) in the condition that other companies would also be able to get that data to start their own programs too.
Treat space infrastructure as an investment and make it make money. Them it'll take care of itself
My only issue is with human greed. A tree does not refuse to fall because it wants more value for doing so. A house cannot ask for more money for its existence, people do. Vehicles cannot decide to not operate when fuel prices rise, people do. When will it "top out"? When is enough enough?
@LadyAdakStillStands a tree refuses to fall because it's existence depends on it. Let's not get into the evolutionary/biological parallels with economics because it will be a very long conversation.
Houses are built and owned by people, they aren't alive and don't act at all. This is apples to oranges.
The entire premise of economics is that wants are infinite and that resources are limited. It's a model that has been applied successfully for most of human history. Without greed, human progression stagnates. Greed comes with the drive for growth and exploration that has gotten us where we are. Does it need to be balanced against other things? Absolutely. But it's still necessary
It wont work like socialism isn't.
We take this channel by granted, but it is really such a gem within UA-cam!
Many thanks for your informative and artistic videos Astrum.
The idea of planting trees under whose shade we’ll never sit encourages us to think beyond ourselves, focusing on the kind of world we want to leave behind. Whether it’s through kindness, hard work, or leaving something enduring for the next generation, it’s a powerful call to make our actions count.
The speeding up as it left fascinates me🤔
Gravity assist from Planet 9?
No. Any putative 9th planet would be way too far out ( >100 A.U.) to have any significant effect on objects in the inner solar system. Only something like a star could do that and there's only one in our solar system.
…….”Gotta get the hell out of here”
it didn't speed up as it left, but it slowed down less than it should have. many people believe it was speeding up due to the term 'acceleration' describing it's change in velocity, but in physics unlike in everyday speech, acceleration only means force being applied to change an object's movement, not necessarily speeding that object up
Probably outgassing. It's never aliens 😅
Your voice always has a smile - quite a unique ability.

@@trol68419 [insert photo of ratty-haired UFO nerd here]
I give it %0.000001 chance.
If there are aliens out there, they wouldnt be right next to us dont u think?
And why not? We have exactly zero statistical data, but plenty of evidence of evidence being covered up....
If only we knew!
The way I see it, the effort is never wasted: we would gain SOME knowledge in the doing of the tasks necessary, we could potentially gain knowledge during the flight (the craft WOULD pass by and through several regions of the solar system that we've not studied much), and then we'd gain knowledge "at" the target object. This all holds true for Project Lyra and the Comet Interceptor, and just about every other mission that the space science folks can come up with. None of them are fools, they would pack as much science into any given trip as possible. And honestly? Catching up to THAT thing in just over 20 years? That's pretty damn good. It's just so difficult to really grasp the distances involved for us "lay people" as it were, there truly isn't anything on Earth that gives us even a hint of astronomical scale.
But as you rightly point out, politics (not so much economics actually) is going to be the problem, as it always has been for space research. Governments are just like corporations in this much: they only get excited when you tell them they're going to make a lot of money off a given venture.
Great video! Greetings from the Project Lyra team
Space exploration is always economically viable. People get paid to design, build, and manage those missions. The money isn't loaded into the spacecraft and launched into the void. No matter who profits the money stays here on earth, in the economy.
Worth doing. The expense is not going to be in launching the probe, it's going to be monitoring it all that time. Still, worth it. It's not like it won't collect data as it goes out. Also, we're in an era of drastically dropping prices for mass to orbit. Lots of these "yeah, but we'd have to have something huge, so no" missions will start to become at least a consideration. Falcon Heavy didn't initially fly much because nobody designed a probe that needed the lift capacity. Now they are and New Glenn, Vulcan, Terran R, and Astra's rocket 4 ... Oh, and Starship ... will allow people to go even bigger. Bigger or more often. Both are good.
Anyway, Eventually we'll send a probe and eventually the labor cost to monitor the probe will be more of a consideration than the cost of the probe or the initial launch. That's going to open up a lot of possibilities.
I’ve worked on a number of long-term deep space missions. Operations costs can be substantial, but I have never seen greater than 50% of the cost of development, and that does not include the launch. Missions that hibernate, such as Pluto or Dawn, have significantly lower operations cost, although sometimes resurrecting the knowledge gained by the last group of operators can be daunting and challenging.
And the 50% one required a LOT of intense activity during ‘quiet cruise’ to adapt to spacecraft anomalies.
Have to give a shout out to the Initiative of Instellar Studies at 5.39, if you check there webpage they have in house artists, one of them is David A Hardy, who is 88 years old! in 1954 at the age of 18 he became an illustrator for a book by Patrick Moore!!! wow, any Sky at Night vitage fans? that takes you back eh?!

It did not catch their eye because it was shiny. It caught their eye because of the astonishing things that it was doing and it's unordinary shape. The fact that it was 10 times shinier was taken into account but no scientists did not get distracted by a shiny object.
Makes you wonder if a piece of our own early solar system has past through another system with life.
An amazing thought
There is a proverb in the navy; "A stern chase is a long chase!"
I think it's a better bet to keep an eye out of for objects like this and time a mission where a probe could intercept it rather than chase it. It has been done with comets already with great results.
We should absolutely catch up with Ouamoamoa - what a great opportunity to explore something from potentially interstellar space. Imagine the data!!
Data that in the end isn't much use to the average person. Nor does it solve any problems here on Earth. It's all just another way to spend billions upon billions of dollars because as they always say (like you do), "we have to find out" or "we have to know".

Another consideration is communication with the probe at the rendezvous distance. There are ways to achieve low bitrate communication at that distance, but no ground network that currently exists could support this mission. Significant investment in ground infrastructure would be necessary.
Chemical rockets don't have enough power, but we have options. Nuclear electric would be helpful, mainly to decelerate over years as it approaches. Nuclear thermal if you're impatient.
To me it would be best to research more into locating further objects like that, a capacity we lack today. Instead of chasing one object for 30 years, it sounds more sensible to prepare to find more of them. I am pretty sure we get many similar visitors every year.
Thanks for another excellent video Alex.
In my opinion, chasing Oumuamua would be a great waste of time and money. However, for any new and similar type object in the future that might be worth pursuing, the Solar Oberth Manoeuvre would be the best method for such a mission. But you neglected to mention that - after executing the manoeuvre - the heavy heat-shield could then be ejected, opposite to the flight vector and effectively act as extra reaction mass, thereby further increasing the craft’s Delta-v. Additionally, after ejecting the heat-shield, and at a sufficient safe distance from the Sun, a Solar Sail could be unfurled, which would also considerably increase the acceleration of the spacecraft.
Many thanks and All the Best. Paul Conti, Wales (UK).

Thank you for this vid! I don't understand UA-cam. I have been subbed for years, but the last video that came into my feed was ONE YEAR ago. I completely forgot about this channel unfortunately. But today YT decided to bring it back under my attention again, hooray!
Astrum, I had to chuckle when I noticed that, at 1:09, you decided against trying to pronounce Haleakala. Just for the record, (Mt.) Haleakala Observatory (and National Park) = hah-lay-AH-kah-lah (Hawaiian for ‘house of the sun’; 2nd. syllable often Anglicized to ‘lee’; located on Maui).
The appearance of Oumuamua may be a lost opportunity. However, we're in a "historical curve" in regard to our technological evolution in regard to occurrences like this.
We've known for decades, in regard to astronomical science, that these kinds of events occur (see, just for example, the general concept as vividly displayed in the fictional novel "Rendezvous With Rama" by Arthur C. Clarke, decades ago, though in that story such occurrence was far more significant in import) - and Oumuamua simply happens to be the first time in history of actually seeing it.
There's also the case of Comet 2I/Borisov, which was observed not long after Oumuamua.
Those of us alive today would love to pursue Oumuamua, as discussed in the video here.
But, of course, humanity could also just PREPARE, and be ready for the next time - even though we have no idea when that "next time" will happen.
Technological development/evolution is going to continue, and in the future, humans involved in such kind of space exploration may be much better situated to take advantage of this kind of "random" event to launch an exploratory mission. So even if we don't do anything about Oumuamua itself, that shouldn't affect humans on Earth from being better situated to exploit such opportunities for engaging in this kind of exploration missions in the future.
Its shape and "toppling" rotation are a great way to create artificial gravity on one end if it were a spaceship.
Like the carriage wheel
If it were an alien probe that is programmed to go star to star. Possibly the change in direction was the computer course correcting the gravity assist of our sun to go to the next star on its list.
Do we know the next star it would reach on its current path vs if it had not changed?
Oumuamua watched this and has now made a U turn and is on its way back. Earth standby…
Thank you for enjoying this reading of the fable:
"The ohmoomoo that jumped over the moon."

Wait for me! I'm coming too!
The acceleration and trajectory are very peculiar. Also they said it was covered with space dust, expected on something travelling through deep space. Yet, it was still 10 times more shiny than a comet. This taken together with its unusual shape, you have to say there is a significant possibility this wasn't natural.
An object like Oumuamua passes through our system about once per year. This particular object was only visible for a couple months before it was too far away for any of our telescopes. The LSST is projected to identify up to 70 of these objects per year. I swear this is the same type of math I'm hit with by used car salesmen.
There have only ever been two interstellar objects that have passed through our solar system though?
@@corporatecapitalism Watch the video.
The fact that it accelerated like that is rather interesting. I wonder what could have made that happen. I feel It’s totally worth it. SpaceX and all can sponsor a rocket too. Could be good long term marketing.
But it’s definitely one of the closest interstellar objects we’ll ever get by a mile(pun not intended).

Say Oumuamua fast ten times in a row at 3am in front of a mirror and you might just teleport there
I’ll be doing this tonight. See you later, nerds.
Even though I love space stuff (I’m here afterall) I couldn’t think of a worse way to spend research money than chasing that thing. Heck, if the trajectory we observed was SO far off our expectation, what are the odds that trend doesn’t continue, and, it’s now nowhere near where we expect?
I hope they put flashing blue lights on the probe that catches up with Oumuamua .
I think its safe to say it broke the speed limit enough for us to put it in jail
Hopefully the jurisdiction will allow us to request the bodycam footage.
Probably similar to the small spaceship that is chasing the dead astronaut in the film "2001" - the bleeps that are given out.
I think it might might be a metal piece with some unknown molecular bandage , probably a left over of an explosion . Its trajectory amd the angle of its journey really made us think all these but it’s not an alien sent object or shape that is meant of long interstellar journey or can generate power of its own .
In aeons to come, Oumuamua will arrive at another star, and the astronomers will trace its trajectory back to Sol.
If they only knew ...
Thank you for pronouncing Oumuamua properly
LSST can find 70 space cigars a year..... yeah!
Just to be clear: NO! No, there is NO OTHER WAY to alleviate our curiosity as to whether we can catch up to Oumuamua EXCEPT trying to actually catch it. Go Humans!
I think hitching rides on celestial objects with lots of power options for ongoing data retreival and images from wherever it goes would be amazing.. Turning it them all into observitories
That would be an interesting and possible concept
Maybe by the launch window, they will be able to use something like the EmDrive or some other propellantless propulsion to slow it down. Would be ideal since you'll have practically unlimited deltaV with no weight penalty, but it will be limited to very low thrust-to-weight ratio. It will have plenty of time to slow down while it approaches since this propulsion would be entirely electric.
Elongated, cigar shape, a kilometer long, shiny, changes it's trajectory without any visible means of propulsion. I don't wanna sound like a conspiracy theories, but I think that's an alien spaceship.
It's crazy how Oumuamua keeps popping up in my existence.
Have always thought alien craft would be made from rock and stone, the stuff lasts for millions of years. Some rock even has magnetic and thermal properties.
Why not? The U.S. military talked about manufacturing aircraft carriers out of icebergs, or an ice and sawdust composite, during WWII. The idea was abandoned, not as impractical, but as of limited utility due to such a vessel’s operating area being limited to the Arctic. Had we gotten an earlier start, they could have been immensely useful as a virtually unsinkable airbase with which to protect convoys in the North Atlantic.
@@richardletaw4068 it was the brits not the americans look up project habakkuk, it also was shelved due to impracticality since they were already in the process of building better carriers
Steel, Aluminum and Titanium also last million of years if it doesnt corrode
@@richardletaw4068 It was a British project and it was abandoned exactly because it was impractical. It was to operate in the mid-Atlantic in temperate waters, which pykrete (the ice-sawdust composite) is capable of withstanding. The issue was that you could build several conventional aircraft carriers with the amount of steel needed for a refrigeration facility large enough to produce the pykrete in a reasonable timeframe. I think in the context of space travel rock could be an effective and extremely cheap method of shielding against radiation, the problem is it's quite heavy so may only really be useful for space stations that don't need to worry about payload capacity and fuel efficiency etc.
Most metals will last millions of years in outer space too. There is no 02 or water to cause rusting or corrosion

3rd trajectory option - Build Freeman Dysons Orion drive, and set a direct intercept. It would easily catch up in a few years. It's a travesty Project Orion was never continued and built, at the very least as a form of emergency asteroid impactor defense.. A missed opportunity, but it's never too late.
Took a month to notice it, by then it was passed and long gone. No chance to notice anything coming our way heh, considering we about to re-enter the galactic dense disk, i`d say this was just the 1st of many in the following many many years. Who knows how many more we might have missed..
Right on. Thanks for sharing.
Chasing Oumuamua seems like a waste of time, resources, and money. I would suggest that rather than going after Oumuamua, we work on being better able to detect interstellar objects before they reach the Solar system so they can be studied. We didn't detect Oumuamua before it was already on it's way out.
Well, first of all it will help us develop better tech, and second
This is our version of cathedrals, we need a grand spectacle every once in a while, we need to do things to show that we can do it, because we are humans, we want to be more
So you want to miss a chance in a millennium? Oumuamua could potentially be an alien spacecraft or something completely unknown. Even if it's just a rock, it's from a solar system that is alien to us.
@@Lone_Star86 The video states it is traveling quite quickly. We would have to build a probe in record time, sling shot it around several planets, and then HOPE it catches up with Oumuamua. No. Let's consider Oumuamua as a lesson that we need to improve our tech to locate interstellar objects better. Let this fish go and build a better pole to catch the next one.
Please launch the mission guys. we must KNOW!
Isnt it strange that it used a similar manuever to fall to the Sun to get a boost out of our solar system just like the proposed missions route? To chase it? ...duuude what if that is a craft or probe from another stellar society
Just because we've never seen an object like this doesn't mean the Universe isn't full of them.Wake me up when the next one actually stops for a Coffee...
could we catch up to it? possibly, it would be a major risk with a very VERY high reward if so. but is it worth the money it would cost to do so. no and i'll explain why, the composite of oumuamua is going to be nearly the exact same as the asteroids we would see here. the composition would be nearly identical to terrestrial asteroids. it would be mostly water ice with some possible methane, and some other slightly harder elements that help it to make its form. again its a big risk with a big reward if we do but we already have a good understanding of what its likely made of. its just the specifics is all we are really wanting to know.
And that in the end doesn't help us in any way, shape or form. Not a single person can rationally explain why following it, studying it and knowing about it is relevant or worthwhile. All anybody says is "for humanity" and somehow we have to know all about it just because. But it doesn't change a dam thing here on earth or in anyone's life in any relevant way.
Its 19,342,228,920.68 kilometres away from earth now... approximately... working on exactly 7 years.
This will NOT happen.... it's apparently travelling at 87 kilometres per second, not the 26 you said.
No, it's velocity at infinity (i.e., far from the Sun, where it is now) is 26.33 km/s. It's velocity at perihelion was more like 87 km/s.
I would assume that people behind Project Lyra study were somewhat competent in estimating that it would be very hard but we probably could at the very least go by.
Although aside from the mentioned issues including costs and political will there is also quite possibly delaying/cancelling other missions (Dragonfly could be one of them since it also needs some precious plutonium) and there really isn't much time to the mentioned launch windows.
@@ImieNazwiskoOK The thing is, yes, it's moving away (at about 6 AU per year) but it's going to be out there for centuries and there are plenty of repeating launch windows, which is why I say we (humanity) will send something there sooner or later.
Presumably the actual position of oumuamua was tracked for a long time and used to derive the anomalous acceleration. Is there a relationship between that acceleration and distance from the sun? Perhaps even an inverse square law suggesting the acceleration was caused by solar radiation somehow? If so then Occam's Razor implies that it's a natural phenomenon. Otherwise there is indeed a mystery.
Sounds like an obvious question and I'm sure people are going to say that scientists have already thought of that. But all I've heard is that there was an anomaly. I've never seen a function of that anomaly plotted against time or solar distance. It would be very interesting to see that.
important to note that although oumuamua was subjected to an acceleration, it didn't actually speed up the object, it just kept oumuamua from slowing down quite as much as it should have. acceleration in terms of physics doesn't always mean a net gain of speed.
@ Thanks for that - makes sense. Apparently the Marco Micheli 2018 paper determined that the measured acceleration vector always pointed approximately radially from the sun. This to me suggests a natural phenomenon even though the precise mechanism is unknown, ie no outgassing observed.
@@sbrown314 if i recall, a prevailing but conjectural theory is that it is largely composed of nitrogen ice, which would not only be volatile enough for the push, but wouldn't leave a visible coma
@@peabody3000 That would seem far more plausible than the alien tech hypothesis 👍
There should be cameras out there photographing any thing that comes into our galaxy
Wow.
The video only deals with how to gain enough velocity to catch up with Oumuamua. It raises the question of how to spot it and how to slow down with no gravity assist possibilities. Perhaps the probe could use radar to detect the mystery object.
Take the controls and pilot it back to Earth👍
To the way I clicked on this video so fast- I love you, Alex😂
By the time we get to it, it would be so far away from the light of the sun, and so dark that it would make it next to impossible to observe it in anything but infrared color, if it is still emitting heat
As long as any object is above absolute zero it emits radiation.
But we can also just put a flashlight on the Probe and use a normal camera again :D
If we haven't detected another one yet, how NASA knows they are all similar to oumuamua an how common they are? The interesting thing about Oumuamua is that no one has been able to classify it, it neither a comet or a asteroid or come up with a possible reason why it accelerated out of our solar system that fit the data. We don't yet know if other objects of this nature will do the same thing.
Sorry to be pedantic, but it's 'other star systems' not 'other Solar Systems'.
If you want to be even more accurate you can say "other planetary systems" when the star system in question has planets orbiting it.
We should do both missions!
AND have a mission just sitting on the launch pad waiting for another one to pass by...
maybe I didn't listen to the video very well but To catch up with Oumuamua, we must take into account that the Earth and the object are moving simultaneously.
The speed of 'Oumuamua: 87.5 km/s
The speed of the hypothetical probe: 70 km/s.
Since we are trying to reach an object that is moving faster than the probe, it would be impossible to catch up with it under these conditions.
With a relative speed of 17.5 km/s in favor of Oumuamua, the distance between the probe and Oumuamua would increase by 1,512,000 kilometers per day. This means that at a speed of 70 km/s, the probe would never be able to catch up with it and would move further and further away from it.
Save your resources...it or something like it will be by...
He said it slowed to 26km/s.
9:09 I find it absolutely fascinating that we have machines like this. Pluto was discovered with a blink comparator a mere hundred years ago. The next hundred years?
Typical humans: "Oh look, Oumuamua!"
Several years later: "Let's chase it!"
Pretty much sums it up right there. Let's chase it and find out. Because somehow for some reason we have to.
Imagine we build a probe that sling shots around Jupiter & the sun, catches up to Omuamua, slows down to match speed, & Omuamua activates a warp drive/hyper drive and zips away. 🤯 a few billion dollars used for 2 secs of data but proof of advance alien life. Worth every penny.
