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

@Canthev

@@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 :)

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!

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.

The satellite seems to slow and accelerate a few times and change headings about 3 times with an overall change of corse at about 60*. seems very extreme for a sat to be able to do this extreme maneuver as in the video it explains a corse heading change can be up to 3* this is much more. (granted this video is from 89' so many we have greater abilities) would love to know if there is anyone who might be able to look at the video and enlighten me.

8:12 imagine shooting an Ak47 on that mountain and 90 minutes later it comes back and hits your head. lol.

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.

Very good.
