Hi, I know you posted this a while ago but I am about to begin my degree for space studies with focus of Aerospace Science and since they’re somewhat similar (obviously yours probably much harder) just wondering if you have any tips to do well. I’ve been doing some prep by watching videos like this since I know my first two courses are Intro to Orbital Mechanics and then followed by rocket propulsion
@@Chronicl3x you'll do great. It'll probably be hard but you clearly seem to have an interest in the field and passion for the knowledge will be the biggest asset you have to make graduating easier. The coursework I went through was pretty hard and there were LOTS of classes. What made it bearable is that I was genuinely interested in what I was learning. If you go into the classes really trying to genuinely understand the material, it will be MUCH easier than if you go into the classes just trying to get the grade you're looking for. If you find that the coursework isn't as cool as you thought, there's no shame in switching majors / degrees. Most of the coursework builds on earlier coursework so if you don't like the early stuff you probably won't like the rest of it. And again, striving to have a great understanding of the early coursework will make the later coursework much easier. You got this :)
Connor Weaver I see, but well, i am a control engineer, orbital mechanics is not my strongest point, but somethings i have learned had helped me in KSP, at least the theorical part.
This was one of the best videos I've ever seen. Educational on a very technically challenging subject and yet explained in a simple way that's easily understood. Thank you NASA!
Because trends in the school system starting in the late '80s early '90s have created entire generations of humorless oversized children that respond to pizzaz rather than fully functioning adults interested in quality content. (The same reason for the push for ever more overbearing paternalistic gov., children want to be taken care of and don't have self ownership. Fed spending at the peak of the New Deal was 10% of GDP, mid '60s with cold war, interstate infrastructure, and Vietnam 16-17%, then creeping to 19% by late '90s and peaking at a full 25% in 2009-10, remains over 23% of GDP today.

NASA will still work with you on content, or point you in the right direction if you contact them. Keep your questions concise and direct to them, and you will get a good reply.
Why the crappy modern crap? Because "getting views and maintaining engagement" competes with Chuck Lorre's cynical assessment that Americans, in general, are more-than-happy to leave 'the tough questions' to geeks like Sheldon Cooper & Co.

Orbital rendezvous was made possible by Buzz Aldrin. He understood the physics behind it. He wrote his doctoral thesis on it. Early on in the Gemini program, they tried to rendezvous with the Titan-II second stage booster, but failed. They would do a burn to add velocity and found themselves getting farther away from the booster! They didn't realize that by adding energy to the orbit that the semi-major axis INCREASED and they went higher and actually slowed down with respect to the booster. Aldrin calculated that you have to decrease the orbital energy, drop into a LOWER orbit, then you travel faster than a higher orbit object! Then once you are almost under it, you add energy back to raise your orbit to the booster's orbit and then rendezvous!!! This was one of two major things that Aldrin contributed to the space program that got us to the moon. The other was putting a capsule under water and showing everyone how to work in zero G!
@@jesus4400 No .. some tin foiled conspiracy lugnut ambushed him with questions out in public, accusing him of being part of a NASA deception.

This is the most information-packed explanation of orbital mechanics I have ever seen! The efficiency of this video is incredible. No time was wasted. Cover a topic and move on. No superfluous talk. Awesome!
Spoken like a true new yorker. I am glad it didnt waste time because I am going to have to watch it again. While I was processing some concepts (the area/time relationship, which had caught me off guard) the video was already addressing others.

Good stuff, democratization of knowledge. Were you understanding it well? Some will, some won't, you know. It just depends, but we'd like to hear your story.
I'm glad that other people enjoy informative, intelligent and interesting content such as contained in this video today.. when I look at the youth of the world and the media I become discouraged for the future of humanity... here, is where I find small additions to my hope for humanity.. people who take the time to research and learn about reality instead of spouting some big worded BS they heard on GlobeBusters or some other Incompetent Dunning-Kreuger Award know-it-all website.
+Rob van Kemenade LMAO! And in case you were wondering about that STS landing, 230MPH = 102.819 m/s. Now go land some shuttles! Also check my channel to see my 1088-part ISS or KISS as I like to call it(in 64bit KSP 1.1 pre-release).
I love these old videos. They seem to get right to the point and assume the audience is not an expert but able to grasp complicated concepts. I think today most information is filtered to make it as simple as possible and that is fine I understand they want to be able to reach a wide audience but you lose a lot of what I call fun details in the process.
Always having an interest in astronomy back in 1979 the forthcoming appearance of Haley's comet was of was of great interest to me. How to know where to look? I bought an Apple II computer, learned celestial mechanics, learned programing and began plotting positions. The comet elements of orbit allow one to calculate the position of the comet in heliocentric ecliptic coordinates, meaningless to an Earth observer. So translate to geocentric ecliptic coordinates, not much help. Next translate to geocentric equatorial coordinates. As across check on the program I calculated a problem using the program then with a hand held scientific calculator and wrote down each step and result. Agreed very well but that was 12 pages of calculations. Little did I know that by the time of arrival there would be how to locate the comet charts everywhere. But wow the learning was worth it.

I'm here because the North Koreans kidnapped me and forced me to build an orbital strike vehicle from disused sex robots in a cave 50km to the east of Pyongyang.
And here I thought that calculating rotational Volumes via integration or solving differential calculus equations was intricate...... Deep, profound respect to the mathematicians / engineers that can 'programme' an orbit decades in advance, to intercept stellar objects for imaging and/or 'sling-shotting' and/or landing ....... ASTOUNDING!! Voyager 1&2 , or the ESA's Rosetta
Omg the scenario given at 7:46 is precisely the explanation I once read in a book in the high school library one day while skipping class 20 years ago. If my recollection isn't faulty, the book was related to Einstein in some way. It is my intuition that it contained lesser-known writings of Einstein. I've always used this explanation over the years when I've had occasion to explain the theory because I found it to be a pretty intuitive explanation myself. What a neat thing to see at 4am on CZcams.
Ricky Bugatti Kerbal Space Program. A realistic space flight simulator. You make a rocket or a plane out of stock parts (you can add shit ton of other parts with mods), and fly your vessel to desired destination (moons, planets, asteroids etc), build space stations, colonies etc. All of it using realistic newtonian physics and orbital mechanics. You can make the game even harder with mods such as Real Solar System, Life support, real life parts. Also, exploding rockets into the ground and watching Kerbals freak out while they fly in all directions is pretty good stuff.
Now I know what all the orbital stuff in Kerbal Space Program means. They don't make teaching material like this anymore. And the music especially really sets this stuff apart!
I can't believe the greatest scientific country in the world (though if you were to count Europe as a whole it'd be close) still use imperial units! The whole world has gone SI for a very good reason!
>greatest scientific country >murrica >it'd be close Got a good hearty laugh out of me. A country where "creationism" debates are still a thing is supposed to be the pinnacle of science? That would be quite sad for humanity.
Jim Panse Some religious bunch actually won a court case and now some schools in the US do teach creationism as a science. . . . . Probably why the "New" NASA SLS is essentially a Saturn-VI
LukeRM It's not that big of a deal, and scientific progress is in this age is influenced predominantly by international efforts, with some countries affording to contribute more than others. As for the American mathematical and scientific communities, they use (and have long since used) the metric system for the most part, but often communicate to the public using the Imperial system because that is the system that most in the general American public are familiar with. Anyone who is comfortable with math or uses it on a regular basis already knows that the metric system is far easier and precise to use than the Imperial system. You don't have to be a resident of any particular nation or aligned to any particular political party to know that.
Jim Panse "Teaching" any aspect of religion, especially creationism, in any secular school system should be strictly outlawed. If a person wants to scare themselves into believing in deities, magic, and angels, that's their own personal business. It should be considered a crime for that sort of stupidity being introduced as curriculum in an educational institution.
Treetop64 That's the thing, it isn't like the two are pretty much equivalent and each side of the atlantic just choses one for cultural reasons, metric is fundamentally a better system. As an Engineering student studying in London whenever we have to unnecessarily expend the extra effort of using imperial units because of some regulations that were written in the US, I wonder why the hell cutting edge engineers don't all switch to metric and make their lives easier and their work more easily compatible with the rest of the world.
Yeah, pretty funny.. forced bullshitery. Similar how "Urban" dialects are being passed down.. where these people dont use possesive pronouns correctly or linking verbs, (i wont try to understand why sounding ignorant, or functionally retarded are solid social goals) So in the future.. all people will say "Is you has a dog?" and "You Auntie be okay?"
"evolution of language is retarded" "i wish everyone talked like a boomer" "i was born in the wrong generation" "my generation is stupid" "i'm in a sea of stupidity"
Thousands of years before Aristotle, ancient east Indians knew not only that the Earth was round but also that it was not stationary. How do we know that? From the names they gave the Earth. "Bhugol" meant round earth and "jagat" meant one that moves. In this day and age, an institution like NASA ought to look beyond the Western astronomical history and give credit (some of it for sure) to other cultures as well. It's not a question of political correctness, but historical accuracy.
Your comment seems to imply that NASA is the authority on all things space. It's nonsense. NASA doesn't have any duty to "look beyond the Western astronomical history"; they aren't perpetuating any misconceptions. You are just as ignorant as a flat Earther who implies NASA is the originator of the globe Earth idea.
they did not empirically prove it, so it is not credible. to believe something and have it coincidentally right is just as delusional as to believe something and have it be wrong.
I've never been able to reconcile these two - 1. objects with greater mass attract each other with greater force. 2. objects fall at the same rate regardless of mass.
@@jimswenson9991 If the force or gravity between 2 objects is dependant on their mass you can't say they accelerate toward each other independant of mass.
@@blackmancer This is because as the mass gets larger, the inertia also gets larger. Inertia is "holding back" the object, while the bigger mass, is trying to bring the object closer, faster. These 2 cancel each other out. Some will take offense, but his explanation was good
Wouldn't it be simpler to specify the elliptical orbit orientation and sense (pro vs. retro) using just two 3D direction vectors? The first would be the periapsis direction, and the 2nd would be the orbit plane's normal direction. There would be two choices for the normal...to specify the circulation direction of the orbiting body, you would choose the planar normal which makes the circulation always CCW in the XYZ frame where x is the peiapsis direction, and Z is the CCW planar normal. You still need the true-anomaly and the time-domain parameters to pin down motion in time. But, in the age of using vector math for 3D orientations, it seems outdated to be discussing scalar angles (signed?, unsigned?) to convey 3D orientation.

I got halfway through when I read the description and realized this was made for college students, and here I am, 16 with an interest in orbital science
Good stuff, democratization of knowledge. Were you understanding it well? Some will, some won't, you know. It just depends, but we'd like to hear your story.
The German accent for Kepler is a funny, albeit unnecessary touch.
Kepler is Danish
That's why he sounds like it
@@vennstudios9885 you sure?
@@invisiblekincajou maybe
Pleb Plays Kepler was German. Born in Weil det Stadt, Germany. Check it.

I'm glad that other people enjoy informative, intelligent and interesting content such as contained in this video today.. when I look at the youth of the world and the media I become discouraged for the future of humanity... here, is where I find small additions to my hope for humanity.. people who take the time to research and learn about reality instead of spouting some big worded BS they heard on GlobeBusters or some other Incompetent Dunning-Kreuger Award know-it-all website.
Tthis video could have saved me from about ten hours of reading ! Verry well done ! THANKS !!!
I'm going have to watch this again.... lot's of information.
Thumbs up if you tried rotating your camera because of KSP.
Lol
Rob van Kemenade right here! :D
+Rob van Kemenade LMAO! And in case you were wondering about that STS landing, 230MPH = 102.819 m/s. Now go land some shuttles! Also check my channel to see my 1088-part ISS or KISS as I like to call it(in 64bit KSP 1.1 pre-release).
thank god...., i thought i was the only one suffering from this permanent brain damage due to ksp :D
The lengths I'll go to in order to get good at a computer game. I'm determined to learn to orbit Kerbin, it's just gonig to take some time.
I love these old videos. They seem to get right to the point and assume the audience is not an expert but able to grasp complicated concepts. I think today most information is filtered to make it as simple as possible and that is fine I understand they want to be able to reach a wide audience but you lose a lot of what I call fun details in the process.
Right to the point. I like it!
Always having an interest in astronomy back in 1979 the forthcoming appearance of Haley's comet was of was of great interest to me. How to know where to look? I bought an Apple II computer, learned celestial mechanics, learned programing and began plotting positions.
The comet elements of orbit allow one to calculate the position of the comet in heliocentric ecliptic coordinates, meaningless to an Earth observer. So translate to geocentric ecliptic coordinates, not much help. Next translate to geocentric equatorial coordinates. As across check on the program I calculated a problem using the program then with a hand held scientific calculator and wrote down each step and result. Agreed very well but that was 12 pages of calculations. Little did I know that by the time of arrival there would be how to locate the comet charts everywhere. But wow the learning was worth it.
I had an AppleII, but I didn't do that... Envious.
I feel like I'm sitting in the back of a high school classroom with the lights turned off while a bee comes in through the window.
Haahahha
wow they really made an effort to give kepler a german accent
Wow this is the most information rich video I have ever seen.
Vốn những bài hát ngày xưa đã rất hay rồi mà thêm giọng hát giàu cảm xúc của Phúc nữa thì đúng là cực phẩm cover😍
I would like more explanation of the math, say examples, rather than just given the equations
Yeah, it explains the basics that I already know from KSP, and nothing interesting
i learned most of this in ksp :3
me too
The following musical tracks have been used in this video:
Warren Bennett - Dream the Future
Kerry Beaumont - Molecules
Kerry Beaumont - Creation I
Vic Sepanski - Ultrasonic Waves
Everytime I watch this, I learn. I pass this video on to others...I suggest you do too....
I wish some comment overlay was show with metric system values below imperial values (dunno If I call them right). It's worldwide after all :P
Less than 1% of the Earth uses non-metric measurements nowadays.
Who else is here because of KSP?
I'm here because the North Koreans kidnapped me and forced me to build an orbital strike vehicle from disused sex robots in a cave 50km to the east of Pyongyang.
*fist bump*
I'm here because this is easier than Scott Manley
Me! lol
I'm here because of the android game "Space Flight Simulator"
I mean in their defense from your perspective everything is not only revolving around you but you're always at the center. 👍
And here I thought that calculating rotational Volumes via integration or solving differential calculus equations was intricate...... Deep, profound respect to the mathematicians / engineers that can 'programme' an orbit decades in advance, to intercept stellar objects for imaging and/or 'sling-shotting' and/or landing ....... ASTOUNDING!! Voyager 1&2 , or the ESA's Rosetta
Where are the Kerbals?
Amazing how basic this stuff seems after playing KSP
really loved it
This is excellent.
Imagine this is real maths application of earth as a sphere and their are still flat earthers 😂😂
Space for dummies. I feel like I could put up a mission now.
Omg the scenario given at 7:46 is precisely the explanation I once read in a book in the high school library one day while skipping class 20 years ago. If my recollection isn't faulty, the book was related to Einstein in some way. It is my intuition that it contained lesser-known writings of Einstein. I've always used this explanation over the years when I've had occasion to explain the theory because I found it to be a pretty intuitive explanation myself. What a neat thing to see at 4am on CZcams.
It's a pretty widespread example nowadays
I keep meaning to do the maths of this - if you did this on the moon, what speed would the bullet have to go to hit you in the back of the head?
I'm not sure why, but I really enjoy this.
I am now a ROCKET SCIENTIST!!!!!!!!!!!!!!
You did it!!!
lol
KSP anyone?

Kerbal Space Program. A realistic space flight simulator. You make a rocket or a plane out of stock parts (you can add shit ton of other parts with mods), and fly your vessel to desired destination (moons, planets, asteroids etc), build space stations, colonies etc. All of it using realistic newtonian physics and orbital mechanics. You can make the game even harder with mods such as Real Solar System, Life support, real life parts.
Also, exploding rockets into the ground and watching Kerbals freak out while they fly in all directions is pretty good stuff.
Now I know what all the orbital stuff in Kerbal Space Program means. They don't make teaching material like this anymore. And the music especially really sets this stuff apart!
Great video!
I can't believe the greatest scientific country in the world (though if you were to count Europe as a whole it'd be close) still use imperial units! The whole world has gone SI for a very good reason!
>greatest scientific country
>murrica
>it'd be close
Got a good hearty laugh out of me.
A country where "creationism" debates are still a thing is supposed to be the pinnacle of science?
That would be quite sad for humanity.
Jim Panse Some religious bunch actually won a court case and now some schools in the US do teach creationism as a science. . . . . Probably why the "New" NASA SLS is essentially a Saturn-VI

It's not that big of a deal, and scientific progress is in this age is influenced predominantly by international efforts, with some countries affording to contribute more than others. As for the American mathematical and scientific communities, they use (and have long since used) the metric system for the most part, but often communicate to the public using the Imperial system because that is the system that most in the general American public are familiar with.
Anyone who is comfortable with math or uses it on a regular basis already knows that the metric system is far easier and precise to use than the Imperial system. You don't have to be a resident of any particular nation or aligned to any particular political party to know that.
Jim Panse
"Teaching" any aspect of religion, especially creationism, in any secular school system should be strictly outlawed. If a person wants to scare themselves into believing in deities, magic, and angels, that's their own personal business. It should be considered a crime for that sort of stupidity being introduced as curriculum in an educational institution.
Treetop64 That's the thing, it isn't like the two are pretty much equivalent and each side of the atlantic just choses one for cultural reasons, metric is fundamentally a better system. As an Engineering student studying in London whenever we have to unnecessarily expend the extra effort of using imperial units because of some regulations that were written in the US, I wonder why the hell cutting edge engineers don't all switch to metric and make their lives easier and their work more easily compatible with the rest of the world.
The modern British accent hadn't developed by Newton's time
Yeah, pretty funny.. forced bullshitery. Similar how "Urban" dialects are being passed down.. where these people dont use possesive pronouns correctly or linking verbs, (i wont try to understand why sounding ignorant, or functionally retarded are solid social goals) So in the future.. all people will say "Is you has a dog?" and "You Auntie be okay?"
"evolution of language is retarded" "i wish everyone talked like a boomer" "i was born in the wrong generation" "my generation is stupid" "i'm in a sea of stupidity"
Jesus that was glorious to watch.
This would’ve helped me on ksp like 12 years ago if I was recommended this before today
KSP 2 is getting better.
a video flat earthers are in desperate need of watching
It wouldn't matter, they will just ignore it and crawl back into their echo-chamber of circle-jerking
Thousands of years before Aristotle, ancient east Indians knew not only that the Earth was round but also that it was not stationary. How do we know that? From the names they gave the Earth. "Bhugol" meant round earth and "jagat" meant one that moves. In this day and age, an institution like NASA ought to look beyond the Western astronomical history and give credit (some of it for sure) to other cultures as well. It's not a question of political correctness, but historical accuracy.
Your comment seems to imply that NASA is the authority on all things space. It's nonsense. NASA doesn't have any duty to "look beyond the Western astronomical history"; they aren't perpetuating any misconceptions. You are just as ignorant as a flat Earther who implies NASA is the originator of the globe Earth idea.
they did not empirically prove it, so it is not credible. to believe something and have it coincidentally right is just as delusional as to believe something and have it be wrong.
I've never been able to reconcile these two - 1. objects with greater mass attract each other with greater force. 2. objects fall at the same rate regardless of mass.
more mass --> more force, but also more inertia --> same acceleration.
@@jimswenson9991 If the force or gravity between 2 objects is dependant on their mass you can't say they accelerate toward each other independant of mass.
@@blackmancer This is because as the mass gets larger, the inertia also gets larger. Inertia is "holding back" the object, while the bigger mass, is trying to bring the object closer, faster. These 2 cancel each other out.
Some will take offense, but his explanation was good
@@millicentsmallpenny5837 Sorry I am none the wiser from your explanation.
wish we could get series of all topics like this😭
better than Astronomy 101
Thats one hell of a textbook though.. i kept mine.
im here because of
Space Engine haha
Wouldn't it be simpler to specify the elliptical orbit orientation and sense (pro vs. retro) using just two 3D direction vectors? The first would be the periapsis direction, and the 2nd would be the orbit plane's normal direction. There would be two choices for the normal...to specify the circulation direction of the orbiting body, you would choose the planar normal which makes the circulation always CCW in the XYZ frame where x is the peiapsis direction, and Z is the CCW planar normal. You still need the true-anomaly and the time-domain parameters to pin down motion in time. But, in the age of using vector math for 3D orientations, it seems outdated to be discussing scalar angles (signed?, unsigned?) to convey 3D orientation.
One of the best Space Documentary EVER. Look at it all the time. The Space Shuttle at the end reminds me of landing my Sailplane. 5 THUMBS UP 👍👍👍👍👍
F---->>>=MA 🚀
8:12 imagine shooting an Ak47 on that mountain and 90 minutes later it comes back and hits your head. lol.
FEs should watch this to learn stuff before makeing dumb claims without having a clue wt they're talking about ppfff....
Mihai Colceriu-Nicola Please. They ignore what’s clear to the rest of us. It’s a mental disorder
@@allgrainbrewer10 or they just like to troll ppl for atention and maybe make money of it lol
They couldnt autistically scream for the whole 36 minutes..... no wait! I expect the basement is soundproof!
@@theravedaddy :)))))))))))
Nicely explained👍
We really need a follow up video with the spacex’s rockets changing the game
Aristotle did not prove that the earth was round. That was Eratosthenes. You could let Carl Sagan explain it to you.
Good ol Carl

I'll have to watch this video 20 times. I get most of it.
very well explained ................
