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.

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!

Thousands of hours in KSP Enhanced and studying and never understood gravity assists like I did after you explained it so simply! Fantastic video!

4:48 This is the first time I've understood the basic way a gravity assist works. Thank you for the simple and helpful explanation.

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 Caught me off guard 😂

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.

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!

The graphics for this episode were top notch. Love the detail on Apollo and Artemis spacecraft.

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.

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!

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 :)

Thank you so much for explaining this with simplified graphics! Makes it easier for us non-rocket scientists to understand. Subscription added 🙂👍🏿

4:25 You got me there 😂😂

I love these trajectory videos! How about one explaining the math involved in planning an insertion?

Is it just me or hearing the Artemis 1 roaring gave me goosebump and is very satisfying to listen.

Damn. Your Oberth effect explanation is by far the best one I've ever seen. Great Video!

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!

I enjoy how clearly you explain the different concepts concerning the mission. Great video
