[@thomaswade3072]

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.

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.

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.

[@FabledGentleman]

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

[@silience4095]

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.

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.

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.

[@GadgetNeil]

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?

[@unvergebeneid]

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.

[@SpaceflightRocketShorts]

@@unvergebeneid yeah, I was thinking the same about aerobraking, since they could use parachutes while you can’t on the moon

[@originalmin]

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.

[@samfisher874]

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.

[@FlorisJack]

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.

[@falkihr]

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.

[@sntslilhlpr6601]

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...

[@krissp8712]

If it is not a gravity assist because there was no momentum transfer, is there a proper name for such "velocity vector adjusting" maneuvers?

[@krissp8712]

@@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?

[@falkihr]

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.

[@Splarkszter]

There is a BIG misconception about gravity assists. The first law of thermodynamics, states that energy cannot be created or destroyed, only converted from one form to another. Gravity assist's can only change the direction (or vector of speed) of an object, there is no energy given or loosen, you will exit a gravity assist at the same velocity that you entered it, just in a different angle/direction or vector of speed. The only way gravity assist's help to save fuel is in the change of vector of speed of an object.

[@KayC352]

no, gravity assists can give more energy than you went in due to the orbit of the assisting body. The assisting body slows down a little

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 ?

[@jrc1606]

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.

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!

[@Achilles3588]

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 burn to leave orbit makes total sense. It’s like accelerating down a hill in a car… which directly translates to this as the down the hill is the gravity well.

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 )

[@nls.135]

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.

[@grazynazambeanie5963]

@@nls.135 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 .

[@SecretRaginMan]

@@FemboyModels They said nothing about SpaceX though? Both Apollo and Artemis are NASA missions so . . . ?

[@luigi580]

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.

[@grazynazambeanie5963]

@@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

Thanks for this. It's always blown my mind the math involved but that with math the incredible things we can achieve

Agreed! And I can't wait to see what's achieved next. Glad you enjoyed the video. Happy Holidays!

Amazing and very informative video, space and the engineering and calculations needed to explore it never cease to intrigue me 👏

[@primalspace]

Thank you so much! So glad that you enjoyed this video! I really enjoyed putting it together.

[@T1hitsTheHighestNote]

Very good video! Will upcoming Artemis projects use the same orbits?

[@iamablacksabbathsong9765]

Hopefully one day this will be the first step to be able to have a vacation on the moon

[@primalspace]

How amazing would that be? I want to go!

[@SocksWithSandals]

That was a very clear explanation of the orbital mechanics, beautifully illustrated.

[@BojanBojovic]

Incredible video and magnificent animations.

Thank you so much! I am so glad that you enjoyed it!

[@hugohazendonk340]

I've always wondered about orbital dynamics. Very informative. Interesting they would use a grav assist and retrograde orbit

Gravity assists are simply amazing

[@primalspace]

Agreed!

[@tanakaobi]

Best explanation on the internet.

[@primalspace]

Thank you so much! I'm so glad you enjoyed the video.

[@karlfreiha4745]

Great video man, but i wana add something, the oberth effect only applies for prograde and retrograde burns. The opposite is true for radial and normal-antinormal burns

[@Visuwyg]

Were they able to calculate an orbit like Orion did back in the 60s?

[@Skye-Was-Taken]

Gotta say, that’s the best “that’s what she said” I’ve ever seen. Great video :)

[@primalspace]

Haha thanks. Glad you enjoyed it!

[@sarcasmo57]

Wow, that's so rad.

[@Amsok0]

The oberth effect was not explain correctly. The reason why it's more efficient to accelerate at low orbit is due to higher kinetic energy having from pulse from the engine rather than having better gravitational assist. It's due to conservation of momentum generates more energy due to higher kinetical energy gain (due to much higher speed)

[@malloot9224]

Absolutely stunning how well this is explained, award winning class
