Thanks!
As time goes on Universe Today will become more and more relevant, even more so than it already is. Thanks for all you do!
There is just something thats so romantic about the thought of Hubble spending an untold amount of his finite life staring at a particular spot in the sky
God man it must be a absolute dream come true to go to the moon.
Thank you to you and your team for what you do.
Our pleasure!
I have to say, Artemis executed a really funky orbit.
I think I was in a daze after seeing 100K galaxies then Mr Dodd going to the moon! I am so happy for him! Thanks for another awesome recap! Now just waiting for the clouds to clear so I can find my own galaxies 😀
You mean the aerosol-sprayed heavy metal particulates???
Happy to subscribe to your Patreon, Fraser. You and the team more than deserve the support. I have been watching Universe Today for over a year now and I continue to enjoy every new video you release.
On a side note, I've been curious to understand how exactly the Hubble and JWST position themselves (and stay in position) when doing long observations of specific targets. I'd love to learn more about this.
Thanks again for the great videos!
You're willing to pay for the fraudulent content in this channel?!
They have gyroscopes inside to position them by speeding or slowing some to stay on the target.
Your videos are glorious and when the Friday recap video appears it's such a thunderous finale to the week!
Yay! And this was a good one. :-)
The skip maneuver was also used in Apollo missions. There are a series of Apollo mission videos that clearly show the dive and climb in the animated profile.
I think skipping was more of a fear then, than a maneuver.
You forgot to mention that the Artemis 1 landing was ‘Textbook perfect’. I like when they use that terminology.
Hah, sure. :-)
I don't know. I was an aerospace engineering major in college, and I don't know if I'd want to see a landing that would belong in the textbook for SF 435 "Aircraft Crash Survival Analysis and Design"
@@AnonymousFreakYT Well- i guess that would be more “textbook example” of what NOT to do, but you’re right xD
Thank you, Fraser, for your continued reports and emails about the most important missions of human beings... the exploration of the Universe
I look forward to every episode. I am very poor but I watch every minute and like every video. I do what I can. Thank you for your dedication.
The Soyus leak is concerning, for sure! I hope the issue is resolved quickly!
Hubble paved the way, and Webb is following along, paving an even further path - that's what I've been waiting for for decades!
The dust devil traveling the same speed as they do here on Earth is a fascinating detail that I didn't expect, and the silence in the eye of the storm, so to speak, was really cool, too. _~huge grin~_
When I saw the article talking about this explosion, I didn't realize it was planned, at first, and sort of had my heart in my throat for a bit! I was quite happy to find out it was actually planned.
That asteroid idea is fascinating! Quite an interesting idea! I'll be watching to see what happens with that idea, for sure.
The DearMoon trip will be interesting to watch developed, and Tim's getting chosen is really cool, too! The fusion thing, though, from 2 science communicators I really trust, wasn't quite the world-shattering event that the media talked it up as. I will be curious what your view is.
I would double check the skip maneuver and Apollo. I can’t find the source, but I believe it was someone from NASA saying it wasn’t done because the flight controls and computer power were insufficient on Apollo missions.
Great episode!
Hello Fraser! I’m really enjoying your content, sir🫡 An idea for you… I’m an astronomy lover, but still a noob. Recently, I saw an image from JWST that seriously helped me understand the distances that we’re dealing with. They had placed a LY scale on the image. This gave me an idea of the incredible distance. Knowing a nebula is 500 LY’s across gives me a bit more perspective, that helps. Maybe, others might agree..? Thanks, again.
That's really cool, I do sometimes mention the size of these objects, but I'll consider that for the future.
OK, you got my attention. I've signed up for Patreon. You're now part of a very select group of content providers who have convinced me to donate based upon compelling content. Your content is a bargain at twice the price, Fraiser.
As always, thanks much for sharing.
Steve
Love your content! Is Mars' atmosphere thick enough to do an atmospheric skip?
Artemis 1. This is so cool. Broca's area, or the Broca area is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain with functions linked to speech production. 2/8/2021 and I lived again. Broca's aphasia (non-fluent aphasia) Mike Caputo, Year 1 Stroke Recovery, Up Up Up - Aphasia with attitude, Broca's Aphasia, Right-side Weakness, Mark's 22 years-old Stroke: Broca's Aphasia.
Another great video. Glad you're taking your time with the NIFs announcement. A big milestone to be sure, but it's NOT the huge accomplishment you might think. Spoiler: the energy of the lasers entering the pellet was 2 MJ, but in order to create lasers with an energy if 2 MJ, the amplification process required 300 MJ.
Scott Manley explains that the lasers are only about 1% efficient. That tallies pretty well with what you're saying here. Thanks.
@@RWBHere Yes, I saw that figure, too, on (I think it was) Anton Petrov's channel. So it looks like we have it pretty solidly confirmed (they probably all got it from a single, primary source, but as secondary sources, Scott & Anton are both very trustworthy at finding reliable primary sources).
Fred
Thank you have great evening
Well done
Thanks, I'm glad you enjoyed it!
Regarding the ISS issue-- Won't every one of those little droplets freeze, stay in orbit, and become tens or hundreds of thousands of new orbital-speed space-junk bullets for spacecraft to deal with?
Or will anti-freeze just sublimate like water?
Yeah, it'll get blown away by the solar wind.
Question: You said the Lunar Flashlight mission will follow the same orbital trajectory as the CAPSTONE mission, flying low over the lunar south pole to detect water ice. However I thought the CAPSTONE was using the near-rectilinear halo orbit designed to be far from the lunar south pole so as to increase the time for line of sight to the pole for communications later between Gateway and landings on the south pole. Are they using the same orbit or am I missing something? (Incidentally you always do a great job which I appreciate.)
9:17. Webb: 👁️👁️
Thanks for the news, Fraser! 😊
Stay safe there with your family! 🖖😊
Both the inflatable space habitat and the asteroid harvest into a doughnut are each inspired ideas!
As a former many years teacher, I am amazed at how well you can communicate complicated technology into words that can be understood. Impressive.
Well this is elementary school level indoctrination after all. It's amazing how so many people still believe the lies they were taught in school about "space", "space" travel, "space" phenomena, "moon landing", etc. 🙄
is there a full video of the artemis reentry with telemetry? i wonder how much speed they lose before doing the skip, i'm guessing they slow down below low earth orbit speed so they don't go into orbit and they come back so enough
question: Fraser! Long time fan. Regarding water ice on the moon. Would it be dangerous for an astronaut to pick this up from the crater if there would be risk of catching sun light? Would it harmlessly but rapidly sublimate in their gloved hand or would it potentially be more violent and dangerous like a moon rock grenade? Thanks!
Sublimation is a fairly slow process on the Moon -- even with direct exposure, it would take several hours for any observable change to take place in a hand-held nugget, even longer if the ice is particularly large.
Is the heat shield the ablation type like on Apollo or the ceramic type like on the shuttle or something completely different?
Greetings from the BIG SKY.
By the looks of it, IF the success of their fusion test is accurate, we won't be seeing usable civilian fusion power until at least 30 to 50 years from now.
Even if fusion becomes commercially viable as a power source in 30-50 years, it’s VERY unlikely to displace renewables. The cost reductions and efficiency gains renewables are likely to achieve in 30 to 50 years will make them the most ubiquitous power source on earth. Unless there’s a legit major breakthrough in fusion research in the next 5-10 years, renewables + battery technology will make further investment in fusion research an even more unjustifiable search for that particular white whale.
Ring World!!!! Very old sci-fi novel... remember???
Yep. :-)
James Webb Space Telescope Advanced Deep Extragalactic Survey is the coolest name ever!
சிறப்பு நண்பா 👏
The fact that I just listened to a dust devil on mars while sitting on my couch is insane.
Of all the Dear Moon astronauts chosen, Tim Dodd has a definite leg up... specifically because he survived the stress of nearly suffocating in a space suit...
Istn't the habitat pressure test old news? I seem to remember that I've seen this like, months ago.
At 9.00... it all started with Carl Sagan telling us "100 billion" then it raised to "200 billion" then "400 billion" then Brian Cox said in the BBC universe series 2 trillion. So how many galaxies or there now... not a small difference.
The modern estimate is 2 trillion. It probably won't change much more than that now that we have amazing telescopes like JWST. But the average galaxy is smaller than astronomers previously believed.
@@frasercain thanks Fraser. I've just googled it myself. It's way too complicated when you get into the unobservable universe. 2 trillion we can see but what is there we can't see? Jesus H... it's mind blowing. Maybe you could make a video on what's actually possible.
If the actual Universe is infinite, then there are an infinite number of galaxies.
@@frasercain so.... we don't know. The religious people will love this. Scientists don't know 😣
Shot in the dark, but is there anywhere to interactively compare JADES overlayed on top of deep field?
Cool
Glad you enjoyed it.
Regarding the Soyuz: I wonder why, since they had the astronauts suited up already they didn't just retask them to check out and potentially fix (if feasable) the leak? Afaik there isn't a good angle on it from the station as there is a list of ports they can't uncover because of it. They were going to get the arm over to take a better look last I heard.
They are not sure what the leak is, and are concerned that it might contaminate various instruments and windows on the ISS. On that basis, it's sensible for them to keep the EVA cosmonauts well away from it until it has stopped venting.
@@RWBHere I thought they had said it's a coolant leak, if it is then they'd know exactly the risk one way or another.
I don't know what the coolant is but iirc Scott Manley said something about Ethylene Glycol previously being used in his video on the subject but he was unsure what they use now.
Problem not a great idea sending someone out there while the thing is still venting.
Mic on Mars!!
Go Emily L and company!!
Yeah, I know Emily was advocating for it for so long.
What flavour will the first Moon Slushie be?
Fusion hype hit the airways. the energy produced over break-even was enough to power a tiny light smaller than a tiny Christmas tree light. so pull the other one, fusion project PR agents. but maybe this could be the last ten years we have to wait.
Quick question, is Orion skipping the same as when one makes rocks skip on the surface of the water?
I don't think that's a good analogy. The atmosphere has no surface tension. Instead, the capsule needed to steer using its aerodynamic shape.
Love the space donut asteroid idea. Less enthused by the billionaire sponsored moon trip even if Everyday Astronaut gets to go because it's a lot of precious resources being spent on a self aggrandizing publicity stunt.
When I think of that inflatable space station even if it can take the pressure, what happens if it is hit by a small particle?? Wouldn't it be like a pinpoint and a balloon? BANG!!
How do inflatable habitats protect against micro (and not-so-micro) meteoroids?
Does the 10x increase in deep field galaxies mean that the total # of galaxies in universe goes up by 10x?
The inflatable habitat would not see more than 14psi in actual use so that is a huge safety factor.
Ridiculous, in fact!
I wish they'd just have a dedicated space telescope to chart the entire Milky Way and only focus on that to the exclusion of everything else. Minutely mapping its star systems, exoplanets and dark regions between the spiral arms, to build up a clear picture for future stellar travel to habitable planets, when the technology is sufficiently developed to allow human colonisation of distant earths.
That's what the Gaia mission is. It's mapping out billions of stars in the Milky Way.
You sound a lot like Legal Eagle. 👍
Can that fusion power be used for thrust?
not when the energy released (50% more than was imparted on the fuel pellet), 1 MJ of free energy ... didn't account for the 300 MJ that was needed to power the lasers, or the expected 50% loss from whatever system is developed to harvest the energy from the reaction. They just need to be 600x better ... to actually break even.
Not in its current stage, but it might actually be more useful for spacecraft propulsion than power generation in the near future.
If it becomes space rated and more effective, it may be used for generating high amounts of power to run bigger ion engines
Have the build quality of Soyuz gone down hill? Leak again.
Hope Tim brings his orange suit! 🙂
The leading theory right now is micrometeorite
엘도라도의 전설같은건가요
~ @13:30 ... but can it also handle a bullet... i.e., a small meteor... ??
9:22 What if Hubble is looking "north" or "south" of the Earth? It could see all day long.
It orbits pretty closely to Earth, so the planet pretty much takes up half its field of view. I'm sure there are some targets they could get to that are all orbit long, but it's a minority.
@@frasercain Far enough to be in orbit and earth STILL takes up half the view, we really are pretty huge!
The area for the Hubble Deep Field was chosen for exactly this reason as it is in one of it's Continuous Viewing Zones as of course the Earth never obscures the view the the solar north or south. Anything within 24 degrees of the orbital poles are never obscured and can be viewed continuously.
This is of course how they were able to get a 22 day long exposure when the Hubble has an orbital period of 95 minutes.
UAE..wow
Why not just arrange inflatable habitats in a torus and spin that to generate artificial gravity?
At least we can know that the title isn’t click-bait nonsense ❤
Crew Dragon has a capacity of 7. But it doesn't have space suits and padding for landing.
It really has a surprising amount of space inside. I'm always confused why they didn't continue to develop it as a deep space vehicle.
Down with the oligarchs!
I predict Tim will have same amount of hair as u my friend by the time he goes to the moon 😉
If the Russians can't get a Soyuz ready in time perhaps a dragon spacecraft could be launched with no one on board and the Cosmonauts could wear the spacesuits they came up with. Before the Dragon launches the seats could be modified to accommodate the Russian suits.
It’s very unlikely the Russian spacesuit connectors would be compatible with the crew dragon umbilicals.
Why is the universe so big o.o
💗💗💗💗💗
Scientists: we need a microphone to hear the wheels on the sand
Taxpayers: but we have sand on earth just drive it here and listen
Also scientists: that's not the same
Deer moon
The moon is the last rest area until we get too Mars.
YES! Congrats Tim! May the shwartz be with you lol
BTW, I'm letting Yusaku Maezawa know in advance: I'm not available to go around the Moon right now. So, you don't need to offer. Thanks anyway.
Okay thanks, I'll let him know.
17:45 - Before the end of the *decade*?
I am firmly skeptical of the timelines of anything Elon Musk announces - but I'm expecting Dear Moon to launch in 2025-2026.
Typical sea level atmospheric pressure is 14.7 psi. Why does the habitat need to exeed that by so much?
why does nasa need 200psi? Vacuum of space is only 15 psi?
I'm glad that Roscosmos and NASA are still able to cooperate, despite the current political climate and looming nuclear apocalypse. The penchant for these two space agencies to cooperate, regardless of the posturing of their governments is perhaps the best thing to have come out of the Cold War...
Despite the war, the ISS crew is still a team.
@@frasercain
Yeah, makes me proud to be associated with humanity. I dunno if you've seen The Cloverfield Paradox, but that movie makes a very BLEAK point about how easily people might succumb to nationalistic barbarism, even those who were crewed together on a space station.
Vaping that space grown ganja
Whoa.
Subbed to patreon
Thanks a lot!
question? is there any chance of that coolant getting on other stuff like Hubble
if it was so hot,why was there no steam when it hit the water?
The purpose of the heat shield is to quickly get rid of excess heat. Eventually it was just falling through subzero atmosphere to cool it back down again.
the purpose of the heat shield is to protect what's inside the capsule. they still get hot .
can you explain the pizza like hologram beside the sun, projected on the FAA weather cam at wolf creek pass. do somebody have a pizza on their dash while shooting? or is it WEBB and blue beam creating a hologram to make believe there is an incoming planet ?
❓Why hasn’t the Soyuz coolant leak cause the ISS to spin out of control?
The ISS has a large mass of over 400 tonnes so a tiny leak won't affect it, also it has reaction wheels that can easily stabilise its rotation.
It looks bigger than it is. The coolant on the Soyuz capsule is a tiny fraction of the mass of the space station
@@charleslivingston2256Well, that answers my question. Thank you
I wonder what would happen if thy find a galaxy that's red-shifted _past_ the big bang.
350 million years - that's getting close. So that's revealed at 9 days - how does it work, if you look again but for 18 days will you see double the light? What if we sent something up with the solitary goal of staring at one spot for as long as it can?
Ain’t gonna happen. The Cosmic Microwave Background is the farthest back we can “see” using electromagnetic radiation and it was discovered in 1964. It appeared when the Universe was 380,000 years old.
Neither Hubble nor JWST can image microwaves so they can’t see anything even that old due to the cosmological red shifting into microwaves.
can never have too much Fraser 🥰💦
Thanks! Glad you enjoyed it.
Dearmoon will NOT be launching any time in this decade. It won't launch until 2030 at the earliest.
How about mph for the regular folks.
I'm Canadian, so I never learned imperial. Do you convert everything to metric for us non-normal folks?
@@frasercain I wonder how we Americans figure out a 15% tip at a restaurant.
We Americans proudly stick to Imperial units with the other two tech giants on Earth - Myanmar and Liberia.
Multiply kilometers by 0.6 to get miles. It’s not that hard.
Considering most of the world use metric, you are not the "regular folks." By definition you are the irregular folks. 🤡
Can JWST take picture of a wormhole ..
If someone could actually discover the location of a wormhole and it's somehow generating infrared, then JWST could help make followup observations.
@@frasercain Thankyou
Hasn't NASA learned their lesson when it comes to using imperial units? Why are they specifying their requirements in psi?
Hah, they do everything in imperial. I'm often translating to metric, but I neglected that one.
yo i’m from central ohio i guess
If I was a billionaire I would definitely bring Fraser Cain!!!
A lovely bunch of bites.
Regarding the advertising revenue, I think it's losing its profitability because they are so irritating. Often times, advertisements obnoxiously interrupt TH-camrs mid-sentence.
When I am annoyed by an advertisement, I am less likely to purchase a product or service than if I had stumbled upon it on my own.
Nah, the internet is powered by advertising, you probably don't even realize how it's affecting you. I'd way rather be funded by the viewers than having to make advertisers happy.
Elon was planning ahead for just such an emergency. The cosmonauts can just jump in his electric car and drive that back to earth.
i cant believe how few people have even heard of the Artemis program. and how even fewer care. sad.
Yeah, think back to the Apollo era when it was on the news every night.
@@frasercain exactly. it was HUGE. I mentioned this to a friend. "what is Artemis?" and "why are we going back to the moon". sigh.
Why on earth would you test the inflatable habitat to 180psi?? One atmosphere is less than 15psi!
They probably tested everything they could test on the balloon and said, “what the heck, let’s see it go boom!”
17:35 I could be wrong, but I think the need for "human rating" is to fly astronauts *for NASA* ... And I assume there would be some safety approvals for flying passengers commercially ... But flying a billionnaire and a bunch of artists to the Moon and back is not NASA's business to safety-rate; if people want to risk their lives in an advanture, whether it be climbing Everest or going to the Moon, it is their right to do so, at least until the Communist takeover underway, that shoves safety down your throat whether you want it or not while trampling on your rights and freedoms, is complete.
The “Communist takeover”?
Get help.
@@executivesteps You certainly don't need help; you got too much of it.
In August of 2018 there was a 2mm hole discovered in the "orbital module" of a Soyuz Spacecraft while it wad docked to the ISS. There were pictures showing the hole was clearly made with a Drill. There were plenty of rumors floated as to the cause but last I'd heard; the Russians weren't commenting on how it had happened. On another note; Yusaku Maezawa's dearMoon project's original intent was to have Artists from a variety of fields, fly around the Moon with him. It's a fabulous idea when you consider NASA's Apollo era struggled with the idea of sending a Geological Scientist . . . someone other than a Combat or Test Pilot. I luv the idea but Tim Dodd is No Artist. His early days of SpaceX coverage brought a Circus atmosphere to a field that most took more seriously. I'm sure his content has improved since his early days of wearing a fake Astronaut Suit and pioneering the SpaceX "fan boy" rush to idolizing Elon Musk that many have grown tired of by now. Everyday Astronaut's coverage of this New Commercial Space Race has rarely included anyone other than SpaceX and himself. I hope he Up's his game and take into consideration there's more to this than learning to drop a duce in a spacesuit.
How can Hubble stare at the same spot for 22 days if it constantly rotates around Earth?
It's not continuous -- it's a cumulative total of 22 days of observation conducted over a period of 50 days.
Because it doesn't "stare at the same spot for 22 days."
No sane person will human rate the Starship ... but as we know there are no too many sane people in USA ... so who knows ...
Two hundred forty-nine countries? There are not that many nations.
Hm, I'll double check, maybe it was cities. :-)
@@frasercain Excellent. Now, there are far more nationalities, but last I knew, the number of fully independent nations was just under two hundred. 194, I think including South Sudan.
This was cool but I was waiting for some 2pac news to be honest.
You always are. It never seems to come up.
@@frasercain Maybe oneday we will get the new 2pac Lander on Pluto
