Spacecraft Systems Engineering Intro Class Part 1: Rockets & Orbits

[@popkahchin]

i hope it isnt too late to make this comment. i am a person who loves engineering but i am still many miles away from actually studying aerospace engineering. I am glad that you made such video that simplifies things and keeps me motivated. thanks for the free contents. I appreciate

So smart..and explained in such an understandable way!

[@CaptainWicket]

I think I saw you competing in a tv show. It was about really smart and resourceful people completing scientific challenges. Interesting class!

Nice to see a Khmer guy here of all the places. :D

One of the reasons why you can't shoot out more propellent with an ion engine is the limited amount of electricity you have to charge the particles.

[@chanpreetsingh007]

yep.

[@rl9920]

This would have been a good lecture in junior high school.

[@leoliu7492]

Are you serious about Chinese launch vehicle for humans at 6:53? I did not see any escape towers on it, and I think they use CZ-2F to send astronauts to the orbit.

I love Rocket, Drone, Airplane. Thanks for the Informative information's about Aerospace Engineering.

Once my best lectures

[@JPMontello]

rockets are actually pretty efficient if the mass fraction is high. the oberth effect is an interesting example.

[@xaralampos]

Hey Andrew, I am a very big fan! At 07:20, could it be possible that MIT students did not know what the natural logarithm is?

[@doanviettrung]

As +ve ions exit the engine, aren't they slightly pulled back by the -ve end, how big is that effect?

[@BernardoSOUSAstudent]

I believe ion engines put xenon gas in a plasma state, so it's extremely hot.

[@CRAMOSinnovations]

What did he say @0:56 before radiation?

[@shamaparveentaj3261]

very nice and helpful lecture 😊🙏

[@salahzighem7086]

hello !!! Thank you very much respect you, professor ............

[@md.hasiburrahman878]

do i need to have a preparatory course to attend this class

[@AidanShaffer]

Electrodynamic tethers were not mentioned. Applying a charge to a tether which opposes the local electromagnetic field will cause it to push against the EM field if it is moving across the field lines. It is possible to reverse the charge and cause it to drag across the field lines to a lower orbit. Spinning oblate EM fields are another method of propulsion. Harmonics and topology of the fields is important to understand.

ever read David Brin's short story Tank Farm Dynamo? www.davidbrin.com/tankfarm.htm

Thanks Buddy

[@leesong551]

I should be watching my System and Network Administration Lecture.

[@charliepoppy123]

What mit student doesn't know what the natural log is??

[@L0j1k]

Welcome to Earth. It's not WHAT you know. It's WHO you know.

The russian spaceshuttle was moore effektive since it did not carry heavy engines.

[@arjunroy9635]

11:36 what about the space x rocket, they Carry all that fuel tank up to the atmosphere and land it back on earth. So is there any answer or opinion about that?

[@aaronshed]

It's less fuel efficient.

[@doloresvestrich1653]

Excellent video - clearly, simply explains orbits, rocketry, - spacecraft systems . . I can visualize the science . . thank you . .

Thanks for uploading this!

Great lecture with lots of great content. Just a shame about the terrible audience.

[@elfpimp1]

I can hear the lack of imagination in a lot of the answers from the students..

[@areshermes1995]

Not even in college yet and as soon as he said how do we move around in space.... Instantly thought by using an opposite force, mass out is mass/distance gained. What school is this?

[@MidnightSt]

i thought/hoped they are "distributing" the answers... i mean... he asks a question, and multiple people answer, and each only says one thing, while I've already compiled a list of all those answer-things which all of the answering students collectively get to...

[@MidnightSt]

also, I, too, was disappointed that nobody mentioned Improbability Drive =D

[@dompianosongs7769]

I'm wondering why MIT students may not be familiar with the natural log... is this an actual MIT course?

[@peadubbb]

Like I was with the students, the professor ....................... Lol

[@antonstoger6712]

Can this go past light speed then? And if not why?

[@freedom6984]

If you ever travel faster than light you can throw your physics textbook away

[@abcde_ghijklmnopqrstuvwyxz2188]

It's physically impossible for humans.
