>space flight

Sounds like you believe in the meme that rockets work in space. Sorry OP for shattering your fantasy world, but it needs to be done.

When you use logic, reason and actual real science, you realize rockets only work (definition: propel themselves forward) inside an atmosphere. This means they don't work in space.

They can't work in a real vacuum. Any claims of the contrary is a fraud and a lie.

>inb4 you parrot "newtons 3rd law!" like an NPC without any thought involved

That law /isn't/ in dispute here. Appealing to it to "prove" rockets "work in space" shows you don't grasp the fundamental problem here. The 3rd law is 100% correct. When asteroids floating in the vacuum of space crashes into each other, the 3rd law applies. Likewise, the law applies to objects interacting on the ground on Earth, underwater, and in the sky. The 3rd law is 100% real, but it doesn't "do" anything for a rocket when its engine is fired in a perfect vacuum.

You see, the atmosphere gets thinner at higher elevation until it disappears completely (out in space). That's the issue here! And you can't get around that issue. Parroting "newtons's 3rd law!" or throwing math equations around, doesn't magically make the issue go away. That's just you avoiding to deal with reality. Man up and stop avoiding reality.

If you're currently under the "rockets work in space! xd!" spell they cast on you through the entertainment industry and educational system (the indoctrination system), and you want to break free from that spell and shatter the illusion - then see these two educational videos (they play inside your browser):

2nd (also important): https://files.catbox.moe/so2rrt.mp4

Once you know that stuff, then you know beyond any doubt rocket technology will never be viable outside of Earth.

No atmospheric pressure, zero atmospheric density = no thrust. It truly is that simple.

If you don't understand already, then the following videos, in addition to the ones already posted (here >>12016996), may help you understand:

For those of you with short attention spans who have difficulty following scientific presentations in video format, see the pic for an illustration - it will assist you in understanding that rockets indeed do not work in space. You're welcome.

Any resources to help me calculate the delta v from the surface of triton to an impact on mars?

>>12016996
are you also implying things like solar sails, or ion engines wouldnt work?

>>12017006
How retarded are you? Is this bait? You do know newtons 3rd law right?

>>12016834
>starts spaceflight thread
>instantly gets raided by flat earth imbeciles

postan space elevator inspo until the thread gits gud

>>12017057
you ever think about why you want to go to space? do you think you'll go to space before you die?

>>12017066

>>12017071
I feel like I won't see a space elevator in my lifetime so I'm going to research their prerequisites and determine if its realistic then.

>>12017066
>>12017077
The elevator should be here.

>>12017035
See: >>12016996
Read the parts about the 3rd law.

You reacted like an absolutely fully automated NPC. Incredible.

>>12017066
It seems exciting to go to a completely new frontier. Then again it could be just as exciting to visit all the strange locations of earth.. But still, space feels different. Like progress, it's logical to go there.
I don't think I'll ever go, unless there's a way as convenient as commercial air travel is now. At least regarding g forces. I don't see my nerd ass handling 9g burns to leave the earth. I guess a space elevator would be a good idea then. Or maybe we could just send humans to orbit in one of those balloons and scoop them up from there?

Every time I see BC Place in Vancouver I think it looks like the bottom of a space elevator. I could picture a massive cable reaching up to the sky in the middle of this.

>>12016996
Back again? Why?

>rocket engines don't work in a vacuum
finally, get to use this shitpost

>>12016834
momentum exchange tethers are better. They can be used to boost object on a suborbital trajectory to orbit. We can build em' near term. All you need is fishing line. As in the same stuff you can buy at your local fishing supplies store.

>>12017189
How long are those tethers?

>>12017233
hundreds of kilometers. They are lightweight though. The cool thing is that if you make your tether like a net, they can tank satellite impacts. Satellite gets fucked up, but only a couple strands of line get broken. The tether can then pick up more launched strands to repair itself.

KSP with the realism overhall and real earth shit is kino as fuck , and BTFO's orbiter into oblivion

>>12017436
Doesn't that increase the floating point errors? KSP can barely handle the stock size without glitching, how the fuck does it handle RSS

>>12016996
>Man up and stop avoiding reality.

why would there be shill tactics, here, on /sci/...

/sci/ isn't for politics, so no country or organization should be using shill tactics here.

and to do what?

reduce the total industrial capacity of an entire nation by destroying technical knowledge, critical thinking, and education in general?

how could this tactic possibly help warfare in any way?

>>12017189
can it work on ro with principa tho

>>12017443
It just works.

>>12017443
Werks on my machine with no errors as long as every mod is correct for the verion of KSP installed (IE install the previous version)

>>12016996
>>12017006
:)

>>12017444
It's not a tactic, places like 4ch just attract disproportionate numbers of schizophrenics by virtue of their anonymity.
Same thing that happens with El Arcón, people like that need a place to express themselves like everyone else but if they try to sperg out in the real world like they do here they get ignored at best, thrown into the looney bin at worst.

>>12016834
I can't wait for the space elevator equivalent of Columbia.

>>12017066
Alright, so why the fuck build an elevator?

Why not build a ramp? Or a platform used with zeppelins?

>>12017576
if you jump from top of the space elevator you will orbit

>>12017189
Imaging being the pilot and essentially docking within the atmosphere

>>12017006
Nah thanks, pretty sure the earth is not flat

>>12017609
eh they do some actions like that while flying a plane
