But the truth is that it should cost WAY less. It's kind of like road construction budgets. There are so many inefficiencies and so much profiteering in the whole chain that make it so expensive.
True, but that fact doesn't help us any. Right now the choice is "Pay for the expensive thing" or "you don't get the thing". There is no "make the system that makes the thing more efficient" option. Maybe when AI robots do all the work for us prices will come down, but until then this is the system we have to deal with.
@@chrisoconnell8432 Yes these samples are now collected, so we should return them. Making future missions more efficient than this is still an option, AI robots or not. If you hired someone to move your belongings across the country and they made the entire trip just to put it in boxes, you have to pay them again to go back and actually take the stuff with them, you would know you're getting scammed!
@@7heHorror To use you're analogy, it'd be like hiring specialized packers to pack your stuff, then hiring specialized shippers to move it. While here on Earth we have companies that can do both services, with Mars its different. A return mission has NEVER been done before.
Trying to pack AND ship back samples in one mission was deemed way too hard. Breaking it up into two mission, while seemingly wasteful, is at least possible.
I don't know anything about this specific situation, but I always hear sentiments like this from people who have no knowledge of the systems involved and don't really comprehend what the budgets of large official institutions are like.
@@hedgehog3180Accurate.
1:56 the flash frame of James and Kirk is perfect 😂
Had to pause it and use UA-cam's frame by frame feature to see it after it flashed up!
So NASA took the debris without reimbursement?
I'd be "you're paying for the damage and I'm putting this on ebay."
The debris is NASA property. Ie if you crash your car into someones house they don’t own your car
@@shaun5916
A car has a title. A bumper and hubcap do not. If you come knocking on my door for to claim those items left behind, good luck. I don't have to give them to you.
@@fochdischitt3561 Tell that to the nice men with guns and badges that would shortly come knocking.
@@filonin2
Don't threaten me with a good time.
Until you show me the law that gives NASA that authority your argument isn't valid.
i agree it’s a little crazy-making that the story as told here didn’t involve any compensation to the victim.
the object certainly belongs to NASA but the responsibility for damage to the homeowner’s home is also theirs
I never liked that the "return" part of Perseverance's sample collection was left as a to-do item for later. It would be too much to claim "I told you so" given the complexity and costs involved, but it's still frustrating to see those sample canisters slowly turning into tiny monuments to failure-by-procrastination. Even if it was going swimmingly, we're still forcing two missions to go to the same spot, whereas if they had been honest and delayed both collection and return till they were ready, that rover could go someplace completely new.
What's the old saying, a sample in the lab is worth infinity samples sitting on the surface of Mars?
I think it's a lot like the Shuttle program: it was all they were going to get from Congress, and they hoped to pull off a "miracle". MSR never, ever had any chance, really.
Facts brother.
If most of us already had figured this out why didn't NASA? They had to have known that sample return was never going to work as initially thought. Fraser's description of the process at the end of the video is something that was obvious. While it is breaking new ground, NASA should have made a serious effort to defined the entire process and put a reasonable cost on the project from the get go.
What does even matter I mean it's not like it's going anywhere
@@orsonzedd😂 are you serious? They’ll be less than useless in a few years?
In 1995 I worked for Space Systems Loral, and worked on that battery unit. I clearly recognized the device from the pictures. Well, it's good to see they got their use out of it. However they should have packaged this up in a Cignet capsule, and controlled re-entered it over the South Pacific.
My rant about the Martian sample return mission is how sad it is that we can spend hundreds of billions of dollars on war, with no questions asked, and consistently failing audits on that weapons spending - While asking for a single billion for good science that improves all of Humanity's collective knowledge is too much to ask. Our priorities as a species is very, very sad to me.
Just to play devil's advocate, if you were living in a war zone you would be wondering why getting rocks from the moon is more important than getting life saving weapons.
Thought exersize here;
Put yourself in the shoes of a powerful and rich leader.
Picturing it?
Now imagine being extremely stupid in a poaition of wealth and power; because the brain needs exersize.
No no. I mean dumber then you imagined.
Even lower.
How 'bout "knows a few fancy words, and even what one of them means, but doesnt know how to wipe after using the bathroom"
Ok. Right about there. Thats more or less the average politican.
It's even worse than that. The purpose of NASA is a budget they can micromanage in order to pretend to be careful about money. Probably a quarter of 'em are flat Earthers anyway...
And......signal a strong possibility that our residence on this super unique orb may be very short in terms of cosmic time.
We can afford both defense and space exploration. Both are important.
I appreciate your rant at the end. I was working at GSFC on CCRS. I've since left NASA, it is very disappointing to hear that HQ plans to go back to the drawing board. There is NO WAY NASA's going to save money by abandoning what has already been put into the program, which passed PDR. Sigh. It's going to cost what it costs.
To put NASA's "inflated budget" into context:
If the full Federal Budget was represented by a Dollar bill NASA's portion would not even cut into the ink.
The problem has always been that it's highly visible spending. That gives people an exaggerated idea of its amount.
if the federal budget was $1 NASA gets 0.3 cents
@@robertmiller9735 Mikhail Gorbachev invented Glasnost and Perestroika in 1986.
Maybe they were not such good ideas after all???
Example Pentagon Black Budget.
They get about $25,000,000,000.00 annually. They'll probably divert a couple million into a study to figure out why that stanchion didn't burn up as planned. But what I didn't hear in this story... was any offer to pay for the damage to that guy's roof.
@@user-en8wc1lo6c they'll probably get .1 cent once starship is successful and NASA uses it
Would you consider adding "Space Bites" to the title of these to be able to notice them better?
I have had the same thought
I sympathize with the rant but the HLS tender comes to mind as a counter example. 2 contenders fell short of the bar and one left the bar far behind. I'm sure spaceX has full intentions to demo launch from Mars as soon as they are that far along. It's possible to innovate a new path when you discover a dead end. The suggestion that it's easy, is laughable though.
Take Musk out of SpaceX first, then you might get somewhere. With him at the helm, you won't see anything going to Mars from SpaceX anytime soon.
Love this channel, man. Thanks!

@fraser Is NASA on the hook to pay for the damage caused by the ISS debris?
Insurance company “You’re not covered for extra terrestrial debris hitting your house”
I'm happy to see your channel come up in my feed. I blame your ITF-3 interview with Marcus House and Scott Manley.
Space junk is a real problem that no one take seriously. The attitude how space around the earth is managed is disgusting.
Everyone at NASA takes space junk very seriously. The only reason you know its a problem is because people at NASA have informed the public about what a problem it could become if left unchecked.
Starlink had made it far worse
@@chrisoconnell8432NASA doesn't really care as much. The esa is the only one who actually does
@@manoz6194starlink sats are designed to deorbit themselves.
@@manoz6194 Starlink satellites are made to burn up in the atmosphere, parts of the pallet this came from were designed to be resistant to high temperatures (i.e survive reentry). This was a mistake in construction since it's highly unlikely that alloy was really needed for that pallet and also a mistake in their failure to note that the pallet had Inconel parts and therefore was not safe to let go into an uncontrolled reentry.
I see two very serious mistakes here by NASA.
It does however call into question their plans to eventually deorbit the station because it makes me wonder how many other parts of the station were made of such materials.
Thank you for the video!
there is a reason there is a "plus" at the end of the term "cost-plus". i respectfully disagree that it "just costs what it costs". no, it does not just cost what it costs. it costs far more than it should because of people who think that way. in fact far more than it must for us to ever attain "star trek" status. the biggest part of innovation is not actual technology examples, its how to create them better, faster and most importantly, cheeper. this is organizational, motivational, first principles reasoning. i think there are many who would agree with me, and we see many examples right now of innovators acting on these principles. as a result, we also are seeing the contrast in achievement between those who think "it just cost what it cost", and those who know better..
NASA even testified to Congress that the cost plus contracts weren't working.
Congress told NASA to keep using them.....
So nice to have several good choices to votes for!
When you said you were going to rant, you really meant it 😂
You can see the sun shining through mountain valleys on the edge of the moon during a total solar eclipse. The bright spots are called "Baily's Beads" after the astronomer who first explained them. You can even identify which mountain valleys you are looking at by carefully measuring their positions. The best time to see them is around the time the "Diamond Ring" appears at the edge of the eclipsed moon.
Hey Fraser, I have a question about time dialation, that maybe will be in gravity well's favor, or maybe it's just a flaw in my logic: Wouldn't it be smart, to get datacenetrs down to really heavey planets? Calculation time would go faster from your viewpoint in the solarsystem. Like you are in a wide orbit. Can still comminucate with the planet, but profit from faster time dialation on the server side?
Good rant Fraser :)
Nice shot!
I always hated the budget heavy episodes of star trek.
Heh, I was wondering about the "Star Trek said it would cost only X million" too.
Hi Fraser, really appreciate the show. Could you please talk about Lunar Standstill.
19:05 apparently manned mission to Mars is anticipated to happen before the sample return could happen.
Unless there will never be a manned mission to Mars. Then just put a more sophisticated robotic lab on Mars and do it all there.
Could we or should we try cloud seeding mars atmosphere.. it has a some cloud cover with ice clouds. Maybe this could make it rain and we can see where and how the rain water reacts with martian atmosphere and the surface
1:07 that is one chunky piece. was it suppose to melt all the way?
Oh ho man, that would become a family heirloom.
Love the Frazier bingo card
Spot on!
Hi Fraiser,
If we find planet nine, and it turns out to be a five earth mass black hole, could we use it as a slingshot to reach interstellar travel speeds?
If the battery didn't burn up wouldn't that be a good thing to investigate as what ever the reason then maybe it could be transferred into a new form of heat shielding for reentry?.
It wasn't a battery that made it to the ground, it was a structural piece of the "pallet" that the battery was loaded on which was made out of Inconel. Inconel is an alloy which was specifically made to withstand extremely high temperatures.
The real problem here is that they used such an alloy in something they released from the station with the intent of letting it burn up in the atmosphere in an uncontrolled manner. They should have used a less resistant alloy for that part or they should have put it into a vehicle making a controlled reentry where the likelihood of it's surviving reentry wouldn't have been a problem.
Maybe process votes by first, second and third choice and use the preference voting process (also called single transferrable vote). I wonder if that were done if it would still be a close tie.
"according to researchers that's the temperature you want to bake cookies" 😆
Hi Fraser! A question for you! Do we know if lava tubes on the moon are full of nasty, jagged dust, or might they be relatively clean inside?
Q1: What's the difference between a Super Jupiter Exoplanet and a Y-Class Brown Dwarf Star?
Q2: What's the difference between an X-Ray photon and a Gamma Ray photon?
A1: Whether it's detected via the radial velocity method or direct observation.
A2: Whether it's generated through stimulated emission or nuclear decay.
Love this information 😁😊😢
You are a fantastic person, Fraser, as are your team! The work ye do to promote and provide space and science news is second to none. I will be pateroning ye as soon as I am in a position to so, (hopefully sooner rather than later), I cannot put a monetary value on how much you have educated me thus far, luv u xoxo
The battery pack is something that shouldn't be reused anyway. It was meant to come down on a Japanese resupply shipment but there was an issue. One if them got left and no supply pod went up for it so it was dumped. Chance if this happening was very low but there is no plan to dump a pack in this way again.
RE Mars samples/Perseverance etc. Have you seen YT Channel Mars Guy, Dr. Steve Ruff, a Mars geologist (Arizona State University) he has been following Percy & Ginny for years, and super imposes himself or rock hammers etc. for scale, so that you can make sense of the imagery coming back from Mars.
More importantly, are they going to pay for the repairs to that guy's house?
Ranked choice, baby!
My parents live just north of that in Venice Florida. NASA!
A question. Stars like Proxima Centauri (class M) are red dwarf stars. Stars like the Sun (class G) are yellow dwarfs. Other larger stars like Betelgeuse are red giants. Are there any stars that are just plain stars, or are they all dwarfs or giants with no middle ground?
in reference to pop 3 stars, would they not contain trace amounts of lithium? from my understanding a small amount of lithium was also created in the big bang; and so would pop 3 stars not be devoid of metal, but extremely metal-poor?
So this brown dwarf is a perfect place to mass produce cookies?
Perhaps, but there’s a good chance they would smell like methane…
Any crewed mission to Mars' surface would be preceeded by an orbital mission. An 18 month round trip with 60 days in orbit would be a good choice for the 2033-2035 synodic minimum. If the samples cannot be retrieved by autonomous robots before then, then they should be retrieved by drones operated by the orbital crew. Missing that timeframe will significantly increase the delta v costs for any short-stay mission until the next minimum in 2045.
I appreciate your use of "theorized". We were taught that Samaria was the first civilization. Gobleke Tepe disproves that. We don't know what happened 12,000 years ago. Let alone millions of years ago. It's all guesses until someone comes along with better guesses.
I have so many questions about the Vera Rubin Observatory: Will it take photos next to the full moon? In this case, will it take 15 second exposure or less? Does it have a lunar coronagraph? What about a photo with Sirius at the center of the sensor? With solar filter, it could take photos at daylight? Photos with the Sun at the center? What kind of screen the scientists will use to analyse the photos, a grid of 16K resolution monitors or a special monitor? How much asteroids, comets, interestellar objects, brown dwarves, white dwarves, stellar mass blackholes and secret satellites will it find? Imagine a movie of the Jupiter trojans or a Saturn and Uranus conjuction with galaxies at the background! 😮
glad to hear you expand on the process & cost of the mars sample return mission. i hear a lot of the 'why don't they just' nonsense, people are generally completely clueless. these same people get to vote, or become poilticians. and so here we are, in a very unequal world, with a very broken economic system, and until that changes for the better we're stuck with our painfully slow crawl toward becoming civilised.
Fraser - if you still want small channel suggestions, I have two. Kyplanet does good videos on exoplanets and the future of spaceflight. Con Hathy is above your 10k limit (12k) but he makes good videos on the engineering of space.
the longer the return mission gets delayed the less likely the rover will be around this sort of plan should be planed to coincide closely to the mars landing rover
i remember when china did an uncontrolled re-entry, good to see a consistent attitude on this kind of thing.
Thanks for all the news, Fraser! 😊
I absolutely agree with your rant!
Stay safe there with your family! 🖖😊
Can you describe more on GIA BH3.
I want some old NASA in my backyard :-)
Very glad everyone was all right!!
I suspect that independent contractors may be able to complete missions much faster and for lower costs than NASA and I think NASAs new commercial partnerships demonstrate that they realize this too. Perhaps we're going to see a contract mission for sample return.
The Mars samples are important if humans want to go to mars one day. We have to produce things in space. We can't bring everything from earth. That would be too expensive. So we need to do exploration, otherwise we won't know where we can produce things and where we can't.
For example, the discovery of water on moon created an interest in colonizing the moon. And that would be great, because it is so much cheaper to produce things on moon. It is also close enough that we can intervene in a crisis.
Heavy Metal and Florida men's house. What a video... 😄
Pertaining to the electrostatic dust problem, has anybody tested the Dust itself as it collects? has that experiment been done?
I say forget the sci-fi shield option and just copy nature. What do dogs do when they get out of the bath ?
I would love to see a rover shake itself clean from head to tail lmao
Regarding the piece from the ISS that didn't burn upon reentry into the Earth's atmosphere. SpaceX should analyze it for potential insights into Heat Shield materials.
Regarding collecting rock Samples from the Mars surface, you don't need to land on Mars to collect Samples. You just need to get the Samples into a location where they can be collected. An Space Craft put in orbit around Mars could be used to collect the Samples, if the Samples could be ejected from the surface of Mars into orbit.
To eject Samples from the surface, perhaps some type of Missiles with "shaped charges" could be shot from the Orbital Craft into the desired locations on the surface, ejecting sufficient material into orbit for collection. A collection device could be deployed from the Orbiter to capture the Samples, and then the Collector with the samples could be retrieved. Then the Orbiter with the Collector and Samples could be sent back to Earth. This would eliminate a lot of expense, and danger to humans, and could probably be completed in a fairly short amount of time. Sample have been already collected from Asteroid Bennu, and from Comets with the Stardust Mission. Much of the preliminary work has already been done.
I for one look forward to the giant sample-return trebuchet!
@@ericsmith6394 Nice. Trebuchets are awesome! 😉
Spacex does use NASA heat shielding from the latest version of the space shuttle tiles. I can't find the video where the presenter tested different space shuttle tile versions along side spacex tiles.
Kudos to NASA for at least being HONEST about their debris hitting a house, I can think of at least two other nations up there side by side who would absolutely lie their asses off about this kind of thing...
It's a logical fix. Refund the guy for the damage to his house and then learn a new design parameter to avoid the density needed to survive Earth de-orbit. It's not a problem - it's an opportunity.
Whoever made the bingo card is a genius.
On your Rant, if we are not using the systems that would land people on Mars, then the justification as a demonstrator weakens considerably as I see little possibility that we’re going to put humans on Mars on the first full run of the system. So, either the Sample Return becomes the Mars Rocket demonstrator mission or it should be cancelled. It’s hard to justify building a one off system to be closely followed by a completely different system that takes humans to Mars.
That would be a good survey question, "What does one call a satellite of a brown dwarf?"
a) planet
b) moon
c) other (please write in)
(c)gi NASASS
If it's the size of a moon we wouldn't normally consider it a planet so it should be called a Dwarf Dwarf Planet.
(d) Brown Dwarf "Hedgehog" a rogue floater or small wandering CG classturdroid from NASASS.
A broonet
They need to clean up their mess and take responsibility for their actions.
Is NASA going to fix the hole in the guy's roof?
Far less scared by what the universe will do to us than I am about what we will do to ourselves.
Eternal thanks for teaching me things.
I know it's a sort of we had to have tape drives before SSD drives sort of technology thing, but by 2040 the big brains put to this problem will potentially have the technology to send a better portable sample analyzer for cheaper than getting back the samples. Right?
2 questions
1. Does Gravity affect electricity?
2. Are there any planets that have moons that have moons
Question 1 is kinda vague, I mean the gravitational force doesn't directly interact with the electric or magnetic force but time dillation due to gravity obviously has an effect on everything.
You forgot that when it's super hot and super cold, there is electricity created. That is why you get sunlight travel. The sun science might be more complex.
The Mars return mission to return the samples back should have been a single mission with the rover that took the samples/cores. Without it being one worked out mission it was doomed from the beginning.
10:10 isn't that electro-Static? 10:49 can be repelled by electromagnetic means.
Yeah. Static
Re Costs, maybe they should speak to the Indian space agency. That first successful lunar S.pole rover mission, cost something like, $75M.
How do you know that it wasn't a "home"?
I'd love to have someone explain where all those cost come from; especially why they are so much higher than other mars mission.
Of course I don't know the answer. I will say my personal opinion.
I personally believe. NASA is expensive because of all the separate parts that combine into the system as a whole needs testing done to prove NASA ideas are going to work and is not wasting taxpayer money. It seems other nations citizens don't require the same assurances.
I assume the costs come from Congress mandating that NASA do it in a way that's profitable for their home state.
Because it's essentially three missions in one. Instead of just landing on Mars like usual they have to land on Mars, then take off from Mars again, and then rendevouz with a spacecraft in orbit that will return from Mars. And of course the complexities involved and the precision needed goes up with each step. Like they don't just have to land on Mars, they have to land on Mars close to their already existing rover, while also making sure that they're oriented to be able to rendevouz with the spacecraft in orbit. And they don't just have to rendevouz with a spacecraft in orbit, they have to do it in a way where it can still make it back to Earth and then at the very end the sample capsule still needs to survive reentry.
They essentially have to solve many of the same problems the Apollo program solved except it's not on the moon it's on a different planet and it's all being done automatically by robots. This is obviously extremely hard and arguably more complex than the James Webb telescope.
We don't have the technology yet to reach that far into galactic space so that should tell you NO this is not the beginning.
NASA should do a SciFi series tie-in and get Red Bull as a sponsor.
Will NASA take financial responsibility for the damage?
Government has a bad habit of dumping batteries of all kinds. Who fines them for this toxic litter?
Sorry, I'm late but thank you!
Brown dwarf orbiter = planoon/ moonet
I haven't watched the live stream since UA-cam made the audio on live streams extremely quiet.
That's been fixed for a few months.
@@frasercain Sorry Fraser -- I couldn't hear you -- speak up lol
And now we know how wildfires start... What a surprise....
the sample return is more important than 1% of USA military budgetwise. Thats what it costs.
I just watched the movie 'Life' last night
I wonder how long it will be until those samples are completely buried in dust?
I mean there must have been some red dwarf stars in pop 3. Not every star was a giant on the outskirts of galaxies. They must still be around surely.
"Why don't they just" just send an automated sample analysis lab platform to Mars, along with a pair of small, simple sample collector rovers? As tech continues to improve on Earth we could send additional modules to the lab and expand its capabilities. Of course, for a mere $1 billion I could provide NASA with a bucket full of Mars regolith that in no way came from my backyard.
Hi Fraser. Let's let our minds wander off for a bit. Imagine it's somewhere in 2026 and China sends a unmanned mission to Mars and scoops up those US/NASA 'ready to pick up' Mars samples and lands them safely back into China. What sort of implications would that bring ? Could you speculate on that scenario for a minute or two? Thanks, love the content!
15:13 Awwwww ... it's annular.
they yeeted that thing out of the space station
I wonder why there is so much hydrogen and so little else in the universe. Surely in the few seconds after the big bang when quarks were forming into protons and neutrons there would have been enough heat and pressure to fuse hydrogen into heavier elements?
I mean it kinda did, helium and lithium were also formed, but the energy needed to form heavier elements than that simply wasn't present.
@@hedgehog3180 Seeks odd that there is more energy in a superniva than the big bang.
Space. The final frontier. These are the voyages of the starship Enterprise. It's continuing mission: to seek out new cost-cutting strategies and new less ambitious missions.... to boldly go back to the Moon, where man has gone before!
In the U.S. we call biscuits, "biscuits," and cookies, "cookies." In Britain they call cookies, "biscuits." Adding to the confusion 13:05 apparently in Canada they call biscuits, "cookies."
I'm not sure why Anton decided on little biscuits for that clip. :-)
To add to the confusion. The precursor to the Oreo was the Hydrox, called at the time of creation a "biscuit sandwich", manufactured by the Sunshine Biscuit Company, based in Elmhurst, Illinois.
Oreos which were introduced in 1912, were and still are made by NABISCO (National Biscuit Company).

Bringing material back from Mars. Worst idea ever. Analyze it there. We have no idea what could be in them.
how close dose a black hole have to be for it dangerous to us. how would ytou figurethat out.
Close enough to suck in your imagination or a petrified johnson to jump out and crash on your house.
I mean close enough that you can be sucked in by its gravity, so a couple of light years. Black holes aren't actually particularly dangerous as they don't really do much, they're just really big and heavy objects that will suck a lot of stuff in but tbh everything does that, black holes are just the biggest and heaviest. What's actually dangerous is Red Giants, a Red Giant supernova a few hundred light years from Earth could cause a mass extinction by damaging the ozone layer.
@hedgehog3180 🍌👏🤣Ahuh a big fish tale from your personal recollections or extensive cosmic travels??.. Do the terms "theoretical" concept "artist" impressions, photo shop "composite" images and scientist "can only" broadly interpret feint ambiguous "signals".
