In this video I'm talking about the crazy journey of Artemis 1 and why it took such a weird route to the moon. Getting to the Moon is no easy task. In fact, despite the Moon being 500 times closer, it takes more energy to land on the Moon than it does to land on Mars. Every rocket that goes to the Moon aims to follow the most energy efficient route (depending on the mission.) The goal with Artemis 1 for example, was to send the Orion capsule around the Moon to test out all of its systems. The goal with the Apollo missions however, was to land humans on the Moon and return them to Earth. So why did Artemis 1 take such a weird route to the Moon? Stick around and find out.

When do you think Artemis 2 will launch? - Shoutout to Omaze for supporting this video, enter here for a chance to win a custom Tesla Model S: www.omaze.com/primalspace
cant say but 2024 seems to be as we launched artemis1 perfectly
and thankyou for this video i m not finding any detail or simulation of journey of orion spacecraft
Late 2023 maybe
what are the chances of winning a giveaway
Today is basically 2023 in the scheme of things. We're 11 days from it.
Given that this project started in 2012, and the mission was supposed to originally launch in 2017, then in 2022 August had a failure, September had a failure, then launch day had a near-failure.
I think it's going to be start of 2024 at least for Artemis 2.
And there's a solid chance even the contractor-made space suits will not be ready at all in 2024 to put people back on the lunar surface for Artemis 3.
Hello, Zuko here.
I would like to thank Scott Manley and KSP for letting me understand every single one of the terminologies in this video that would have flown over my head otherwise.
some of those did try do do close approaches to my head, in an effort to land, but then got flung out into outer space... 🚀🛰📡
Artemis 1 was dragged back by Aliens.
No Moon mining, please.
Moon does NOT self-rotate.
Moon is holo.
Moon gives light at night to help grow vegetables and fruits by 20%. This helps to reduce famine and wars on Earth.
If Moon is mined, it will be punctured and shrink like a broken flat basketball. It cannot spread light to the surface of the Earth like a convex mirror. It will ONLY reflect to tiny dots on Earth like a concave mirror.
There are invisible structures around Moon to keep the Moon inflated. The inside of the Moon is hollow, like a basketball or soccer. The frequent in and out of Moon rovers, orbiters, and spacecrafts will puncture the structure and destroy the Moon. Earth will have more wars and famine and more inequality.

Best explanation I have heard of the Oberth effect yet! I have been a spaceflight enthusiast for a long time, and its usually hard to understand orbital mechanics without playing KSP, or Spaceflight Simulator for years. I will use that analogy to explain it to my friends a lot!
Thank you so much! I am so glad that you enjoyed the video and my explanation :)
I will also thank him for giving me something new to try, it can help me with a new crewed landing in SFS.

I paused here just to check if comments have gone mad with this
Great analysis. I was born in '68. Too young at 4 years old to remember anything about Apollo 17 in '72. Apollo 12 was my favorite Apollo mission. Three buddies going on a road trip to the moon, "dancing" in zero gravity to "Sugar, Sugar" and nailed the pinpoint landing. Add to that Conrad letting Bean fly the LM "Intrepid" while they were on the backside of the moon on their way back up to dock with Gordon in "Yankee Clipper". I pity the fools that don't believe we went to the moon. Never underestimate what our scientists and engineers can build when given the resources and the skills and bravery of the astronauts. I hope I get to see them land on the moon again before I die. Cheers.
Thank you so much for sharing this! So glad that you enjoyed the video and hoping we get to see another moon landing in our lifetime also! Cheers!
Artemis 1 is only our first test to going back to the moon.
If you can make it to 2025 and all continues to go well, Artemis 3 is scheduled to be the first mission to land on the moon in our lifetimes.
Hang in there! We're almost back!
Great video! Just a small correction, the Oberth effect does not increase your delta-v, that is constant. What it does do, is increase your thrust *power*. Power is equal to velocity times thrust (dot product of 2 vectors). At higher speeds, the change in your energy after a burn is higher than at low speeds, here let's put some numbers into it.
KE = 1/2 m v^2
Imagine you are a 1kg object traveling at 1m/s, that gives it a Kinetic energy of 0.5 Joules. If you it speed up by 1m/s, it is now going 2m/s, giving it an energy of 2 J. That is an increase of 1.5 Joules.
Now, imagine that the same object is going at 100m/s, giving it an energy of 5000 Joules. Then we speed it up by 1m/s, making it go 101m/s, giving it 5100.5 J. That is an increase of 100.5 Joules.
Our delta-v (change in velocity) was the same in both cases, 1m/s. But our delta-E (change in Energy) was higher when we were going faster. This also applies to slowing down of course. This is the Oberth effect, a rocket engine has more power the faster it is going, because it gives a constant acceleration, but changes in speed while you are going faster change your energy faster, the rate of this change is what we call power.
4:25 You got me there 😂😂😂
😂😂😂 I just couldn't help it
This video really helped me understand how space travel can be affected by just simply moving closer or further away from a planet/moon, you explain it so well!
Thank you so much! So glad you enjoyed the video!
This reminds me of the movie Gravity, which James Cameron called "The most realistic space movie ever made". Apparently he didn't see Apollo 13 lol. In gravity you have satellites that blow up and debris circling the earth, and as the movie describes, once the debris has passed, it will circle the earth and come back again in 90 minutes. But this is not possible because if the debris travels so fast that it can circle the earth and come back to hit them in 90 minutes, the orbit of the debris would be further out. That movie had so many mistakes in it, holy crap. Like when George Clooney has some weird force acting upon him, that seem to ignore Sandra Bullock xD
Gravity stops working underwater.
Gravity pulls the moon towards the earth, pulls the oceans towards the moon, holds us to the earth and can’t b recreated in science. However the theory is in fact relative
@@duramaxdad You need to start eating vitamins man, you have average room temperature IQ.
The graphics for this episode were top notch. Love the detail on Apollo and Artemis spacecraft.
Is it just me or hearing the Artemis 1 roaring gave me goosebump and is very satisfying to listen.
You're definitely not alone!
This video is very satisfying to watch and also both extremely informative and very well illustrated. Well done Primal Space. It is a pleasure for our eyes and ears. Bravo! Look forward for more!
Thank you so much! I really appreciate the kind words and I'm so glad that you enjoyed watching as much as I enjoyed creating this one! Can't wait to share what's coming next!
I have always been fascinated by the wonders of space since I was a kid. There was a point where I gave up on the dream, but seeing what we can accomplish today, and knowing that (hopefully haha) I've got years ahead of me, I might actually be able to go to space on day :)
Good luck, l hope you make it. 👍
Bring your long underwear!
Keep dreaming
This is a great video with fantastic visualizations of an otherwise difficult to understand topic; can't stress enough that this was a great job. Just a small correction: the delta V requirements for launch are usually more than double what you listed---more on the order of 10,000 m/s (low earth orbits have an orbital speed of roughly ~8,000 m/s). Really puts into perspective why launch vehicles like the SLS and Saturn V need to be so damn huge.
I love these trajectory videos! How about one explaining the math involved in planning an insertion?
I enjoy how clearly you explain the different concepts concerning the mission. Great video
I have never expected so much KSP skills will help with real life understanding of space missions.
Thank you so much for explaining this with simplified graphics! Makes it easier for us non-rocket scientists to understand. Subscription added 🙂👍🏿
So glad that you enjoyed the video and my explanation! Thank you for subscribing and welcome to the primal space community!
What a great explanation of the Artemis orbit. I'd seen it explained elsewhere but you did it the best. Thanks!
Thank you so much! I am so glad that you enjoyed the video and found my explanation helpful. I really enjoyed putting this one together.
The field of astronomy and astrophysics is so fascinating and breath taking. And it feels so good that you (who is interested in astronomy) are the choosen one to love and understand the universe! And channels like Primal space make it really easy to understand difficult concepts! Thanks!
People always joke about rocket scientists but it's explanations like this that put into perspective how smart the people are that come up with all this stuff in the first place and actually make it happen.
Agreed! Just learning about it all puts my head in a spin sometimes. I can't imagine the minds the come up with it all! Pretty amazing.
Thanks for a clear and understandable explanation of the Artemis flight mechanics.
So glad you enjoyed it!
I've always wondered about orbital dynamics. Very informative. Interesting they would use a grav assist and retrograde orbit
A very well put together video explaining concepts not so easly understood. Well done!!!
I love all of you videos primal space your videos are amazing. I would also like to see how all the parts of the iss came up. And you animations are the BEST! Love them.
Thank you so much for such a kind comment. I'm so glad that you enjoy the content. I really love to make it as well and I'm looking forward to sharing what's coming next!
I am looking forward to studying a career related to space exploration and your videos are perfect. Not only understandable and clear information, but it also transmits passion and interest. Love it!
Have you heard of Kerbal Space Program
I'm genuinely surprised that a video this informational entertained me, especially since it's relevant since this mission was fairly recent. I look forward to seeing the next upload.
Thank you so much! So glad that you enjoyed it!
This is a good video explanation on what its actually doing, thank you for that! Most videos just kinda pass right through without actually saying whats going on and why and how.
Thank you so much. So glad you enjoyed the video and my explanation. Lots to cover in such little time! haha

Fantastic video to help explain the complexities of orbital dynamics!
Amazing video man, its really cool to learn about grav assists, the oberth effect and more being used in real life (and a really good analogy for the oberth effect). Also did you animate the flight paths in the vid? Its really good 👍
Thank you so much! I really appreciate that and I'm so glad that you enjoyed the video and my explanations. I really had a great time putting this one together. Cheers and happy holidays!
BEST explanation of so many things about this flight that NASA didn’t seem to think ordinary people would wonder about!
Thank you so much. So glad that you enjoyed the video as much as I enjoyed making it! Cheers!
Thanks for this. Had been pondering the Artemis trajectory all during the flight - now I get it (I think)!
Thanks so much for the comment. So glad that you enjoyed the video and found it helpful!
The moving walkway analogy for the Oberth effect is really good, props if you came up with that
Thank you so much! I'm so glad that you found the explanation helpful!
It’s amazing how NASA figured out all of these factors on the Apollo missions without launching any rockets before. There are so many moving pieces all perfectly and mathematically aligned to take us there again and again, it never ceases to amaze.

The real reason Orion only briefly came near the moon was because a loss of the craft would have ended the program that is already billions over budget and years behind.

@@thomasw4422 that would be Principia, right? i've heard of it but never played with it
Looks like the Apollo missions worked well without computers. To make it more complicated and taking longer takes a computer.
In reality they had 4 computers running in parallel for redundancy. And one even got damaged by a lighting strike
@@alexplosion_ITA Wasn’t that on Apollo 12?
Thank youuu for this amazing explanation ❤🚀🔥
That's a really good and informative video you made. I wonder, when NASA will lunch their Artemis 2 (Probably May 2024) and Artemis 3, would they follow the same route ?
Artemis 2 should be following the same route but with people. If the SLS for Artemis 3 launches then we might have the Lunar Gateway space station by this point which would be placed around the moon in the distant elliptical orbit shown at 5:32. Orion will dock with the Gateway and then the astronauts will move to the lander (that will already be docked on the Gateway) and begin their descent on the moon. If the Gateway is not completed by this point, then the moon lander will be placed alone in this elliptical orbit waiting for Orion. After the mission on the moon is done, then the moon lander will launch and dock with the Lunar Gateway (or Orion if the Gateway is not yet ready) and then Orion will take the astronauts back to Earth. As of now, it is not known whether the lunar lander will be immediately disposed after completing the mission or whether it will instead re-fuel and wait for Artemis 4. Artemis 4 should be the first launch of the SLS 1B. Orion is planned to follow the same trajectory but this time it will take a new habitat module that will be permanently placed on the Lunar Gateway for future missions. This module should be able to extend the amount of time astronauts can stay around the moon. Artemis 5 will be similar but is planned to instead send two modules with Orion instead of one. A refueling tank for the Gateway and a moon rover. This will mark the end of the Artemis missions unless new missions are added. Who knows, maybe by this point we'll be confident enough to go to Mars.
@@jrc1606 Artemis II will actually just be using a free-return trajectory for safety reasons, IIRC
4:45 Very good and cool video! However, a small correction, gravity assist mattered little in this case. Gravity assist alters the craft's velocity vector and transfers planet/moon's orbital momentum to the craft, however that only matters if the craft is doing a flyby and leaves the dominant gravity influence of the planet/moon to go somewhere else. If it stays in orbit of the planet/moon, then it doesn't gain anything in relation to the planet/moon. From the reference frame of the Moon, Orion didn't speed up nor slowed down during its flyby, so it's irrelevant from which direction it approached. However, Oberth effect did play a huge role in reducing the delta-v needed for orbital insertion. A retrograde gravity assist is used to gain a free return trajectory (or less delta-v intensive maneuver) back to Earth if anything goes wrong.
Well said. It was a decent way to explain gravity assists, but it's completely irrelevant for what Orion was doing. It actually takes more fuel to get a retrograde capture because TLI requires more delta V to get to that point and you don't get that fuel back on the other end. But like you said, it's worth it for the potential free return (which saved Apollo 13's lives).
The explanation of the Oberth effect was just straight-up wrong too, but that's a really hard one to simplify without just resorting to showing the equations so I hesitate to criticize too hard. Closest thing to real life I can think of is how we're taught in drivers ed that a car's speed and its stopping distance is not a linear relationship, it's exponential. But that's also a terrible analogy trying to equate stopping distance with total orbital energy...
If it is not a gravity assist because there was no momentum transfer, is there a proper name for such "velocity vector adjusting" maneuvers?
@@sntslilhlpr6601 I can see the explanation at 7:05 ("gravitational pull") being wrong but the walkway example of the Oberth effect seems accurate. I'm not entirely sure I understand your braking example - initially I had assumed it was just a mv² thing increasing the energy to be dissipated, but are you actually trying to say that in terms of work, trying to stop in a shorter distance requires way more braking force? Or that at low velocities, the same amount of braking force has less decelerative effect?
As far as I understand there _was_ a moment transfer, but the point is that the direction from where Orion approached didn't matter since the goal was to enter Moon's orbit. Same amount of fuel would be expended if it did the prograde capture vs. the retrograde capture. So the direction of the approach didn't "slow down" the craft when observed from Moon's reference frame - the only frame that matters when you want to enter orbit around a body.
Term "gravity assist" is used when the vessel executes a flyby to go towards another body. Then, when viewed from the Sun's reference frame, vessel indeed did speed up or slowed down depending on the approach.
Whoa! I never thought that I could understand it very well in a short period of time!
So glad you found the video helpful! I really enjoyed putting this one together.
I love the way this video was made and I really love the stile of the animation
Thank you so much! So glad you enjoyed the video :)
0:39 Why is that? Shouldn’t it be easier to land on the Moon with low gravity?
Thank you for these great videos!
I also would've liked some more explanation. Maybe the fact that Mars allows Sone amount of aerobreaking plays a role. Or they just meant it's easier to get into a Mars _orbit_ than to _land_ on the Moon. No idea.
@@unvergebeneid yeah, I was thinking the same about aerobraking, since they could use parachutes while you can’t on the moon
Mars has an atmosphere which will significantly slow a spacecraft down, whereas the Moon does not, so it needs to burn fuel all the way down.
Yeah, I wish this was explained more too. They specifically say "land" which must mean they're including aerobraking at Mars with a heat shield and parachutes. If they said "land and return" it should require a lot more dV to go to Mars and back. It should also take more dV to propulsively capture in Mars orbit without aerobraking.
It takes more energy to go from the earth to the moon than from the moon to mars. Perhaps this is what they intended to say. It's untrue the way they formulated it, as you need more energy to go out of the "gravitational well" from both the earth and the moon than just from the earth.
KSP Players like: "Yes yes, a direct insertion into distant lunar retrograde orbit using the absolute minimum Δv, we've all done it"
You know it’s gonna be a great day when you start it with Primal Space’s latest video !!!!

Why I never heard ANYTHING about Artemis and I watch vids on space and astronomy every day?
I watched it on and off live. I have an app that tells me when something leaves our atmosphere (obviously not including secret launches from various countries) probably because nasa doesn't do a good job at advertising. Space x loves to get us hyped. I didn't know artemis was launching till shortly beforehand. Shit just appeared in my app, tho i bet if i went back to unconfirmed launches, i might have seen it

Artemis 1 empty can , not very risky ,,,, Apollo 8 carried three men . Apollo was multitude of times more risky than that empty can Artemis was . The amazing thing is that Apollo was over half a century ago ( 60 years )
Why are you making it out like a higher chance of death makes it cool. I’d rather have slightly more boring ride with a largely smaller chance of death than a risky ride with a high chance of death. Apollo being old and dangerous is not a flex.
@@Spaceguy-nineteensixtynine what I'm saying is they have done nothing that wasn't done more that sixty years ago . What is all the fuss about ? Break new ground " but they have flown farthest away earth than ever before , yes, the empty can did fly 460,000 miles away from earth , but Apollo 13 flew 410,000 miles away from earth and it had men in it ,and was a broken space ship , they still made it back .. land on the moon with a manned craft or at least circle the moon with men or women on board then start the hype . Until then they have done nothing that wasn't done to point of becoming boreing over half a century ago . PS they did all that without the aid of computers like we have now .
@@FemboyModels They said nothing about SpaceX though? Both Apollo and Artemis are NASA missions so . . . ?
You’re making it sound like Artemis is bad for not being risky. Risks are good to take sometimes, but it must be reduced as much as possible when human lives are at stake.
@@luigi580 it's much ado about nothing lol read up about Apollo 8 , Apollo 11 . Not only were the Saturn rockets new , but the computers were new , inputs were in nouns and verbs . And they made it work . That was something to get excited about . This latest flight is just so ho-hum

Thank you so much! I am so glad that you enjoyed it!
Interesting fact the Apollo command and service modual combo was designed to be able to make direct return to Earth from the Lunar surface, this would have been it's only task with a whole other stage doing the landing. The use of the service module engine for lunar insertion and trans Earth injection were designed after the vehicle was finalized.
i think you believe in the easter bunny
this video is very fun to watch and I learnt a lot
Another factor for Apollo was that at the time we were pushing the limits of what the technology was able to calculate in terms of orbital mechanics. They had to keep things simple to narrow the variables involved. With modern technology that’s less of a challenge and we can make more efficient choices on where to allocate mass.
We have definitely come much further thanks to those advancements.
So cool and clear, amazing video. I feel smart now.
Apollo missions also used a free-return trajectory (or close to it) just in case something went wrong. "Free-return" means exactly what it says on the tin: The capsule isn't actually on a trajectory to orbit the Moon, but rather it is aimed for a really high orbit of Earth. You have to do an additional burn near the Moon in order to get the capsule into lunar orbit. Without that additional action (say, if the engine fails) the capsule will return to Earth without having to spend any more fuel.
Is that what Apollo 13 did? I know they were supposed to land on the moon, but due to the problem mid-flight, they returned without having landed on the moon. So, am I correct in understanding that is exactly what you are talking about: the free-return trajectory was used because of what went wrong?
Apollo never happened on the moon and there will not be any manned ship to the moon either.
@@GadgetNeil Yep That's right. And a good thing too.
And a couple of white knuckle course corrections on the way back
Thanks for your work.
I know how hard it is, to create episodes like this. In order to make interesting video, with correct information in it - you have to sit and make big research - going trough tons of sites, literature and encyclopaedias. After that, most of the info is unusable at all - you have to choose most interesting parts for further plot of the video. Then, video editing comes - which is consuming large amount of energy - hours and hours of editing - u have to sit at one place so many time.
It’s easier to make dumb video on tik tok and get million views. So, we have to appreciate the work that has been done by such a channels like Primal Space.
Thank you so much for such a kind comment. These videos are certainly a lot of work, but I really enjoy making them and it means a lot that even one person enjoys them! I really appreciate the support!
Thank you for the video and explanation. I grew up watching the Apollo missions and it seemed like Artemis was taking a really long time to get there but I was not sure.
Hopefully they don't keep using this slow poke method on future missions as that is just a waste of time and leads to a lot of risk of radiation exposure for the astronauts.
Very cool video.... didn't care too much about this mission and had no idea about the different trajectory and orbit vs Apollo. Just a quick comment about ur last graphic about the orbit around the moon... talking about how the moon pulls the object to speed it up showing the object slingshot past the moon counter clockwise. Was this just for explanation like the beginning of the video or was it referring the Artemis mission? Earlier graphic showed the spaceship orbit in a clockwise direction which allowed it to use the moon's counter orbit to slow it down before going into orbit around the moon. Thanks for the video and letting us know about the mission. cheers.
Fantastic explanation. But will next missions do the same pattern, or this long one was exclusive for extended instrument testing?
No, this is the only DRO planned for Artemis.
Artemis II will have a simple free return trajectory (akin to Apollo 8 without ever going into lunar orbit)
Artemis III and later will travel to NRHO, a complex orbit where the capsule is closest when passing over the north pole, and farthest when passing over the south pole.
The plan is to have a lunar space station in this NRHO orbit as well.
