Why is it so hard to get into space?

The posts on this thread are sock-puppeted.

Ok?

It is obvious to any net-savvy person.

Really; it is.

Say what you like, it won't change that.

Now I've said my piece I'll leave you to carry on your bizarre conversation with yourself, which I assure you sounds utterly unreal to anyone with any sense.

You have never met us, so you have no unambiguous, empirical evidence for who we are.

Humourless with the ability to retrieve a sweety from a specially designed complicated compartmented box, hiding that sweet, I'd say it's not to hard to figure out who you people are.

A 'typo' is a spelling mistake; what you wrote was some kind of stoner gibberish soliloquy.

Largactyl is a very powerful drug; please wait until the initial rush is finished before attempting to post in future.

We'll all be better off.

Enough of that though; please return to how hard space travel is; cos, really - ISN'T IT JUST?

I was typing that on my phone's keypad which I am not very skilled at using.  Also, a typo isn't a spelling mistake, it's when you mean to type something but you accidentally type something else due to a mistake in using the keyboard, which is exactaly what happened in my case.

Stop protesting you thick git. You've been shown up; just accept it, you daft twat.

I made a typo, I didn't get shown up.  There is a difference.

Let's remember the OP and get back to the question.

Let's remember the OP and get back to the question.

Why is it so hard to get into space?
Going into space (on a the generally accepted round earth) requires you to move into at least low earth orbit. To do that you need to travel about 8km/s or 28000km/h. That is very fast.

We are limited in how fast we can move through the air due to its increasingly higher friction as you go faster. So you have to exit the atmosphere to be able to orbit. there is still air some air at 160km high.
Oxygen also reduces as you go higher, this means that an aircraft that uses jet engine can only go as high as the oxygen will allow it to, but at that altitude there is still enough air to limit how fast you can go.
The EU Skylon has developed a new type of engine that tries to combine the best of jet turbines with rocket engines. However I do not see a working craft using this technology anytime soon.

So the best bet is to exit the atmosphere as soon as possible then incline to get to orbital velocities.
The reason why all of that is hard (but do able) is that you have to take all your fuel with you.
The higher & faster you want to go the more fuel you need, which in turn makes you heavier requiring more fuel.

At the end of the day, you need a LOT of fuel to reach 8km/s and that is why going to space is hard.

Space elevators are the future. If only we had the political unity to build one.

Although I always thought they would be the future to access space. I have to disagree now.
In the far future some might be built, but by the time we have the means to build a space elevator we would no longer need a space elevator.

'Space elevator'; now you're really taking the piss!

But, hey, why not?

Nothing else about 'space travel' makes sense; may as well push the envelope & see what sticks eh?

Cos there's one born every minute...

You are just afraid that space elevators would reveal space travel as the reality it is.

Space elevators. Hahahahaha. No wonder these globalists heads are saturated in crap.
If anyone's been taking notice, the public are already being groomed into the easy peasy space exploits.
Felix Baumgartner and his red bull gives you wings carry on is the next bet.

Soon, you will send up a balloon and capsule, then a Felix type will jump out with a jet pack on his back. Straight into space and to the ISS, just in time for tea and cakes with some guitar playing spaceship commander.

Soon enough we can all go to space if you can afford the new fully tested fart mints at 2 million a pop. One mint at a time is enough to fart you into orbit.

It doesn't matter how stupid it all gets. It really doesn't. Because the gullibles will still jump up with drooling, gaping mouths, shouting, " awesome."...."wow."

It's scary to think how gullible people are and even more scary to think that the gullibles actually think they're scientists. That's really frigging scary.

I'd like to abuse you but I'll just sit back and accept that you're merely taking the utter piss and do not believe a word you're saying.
If you do believe it, you seriously need to piss off and get a life.

It seems like a crazy idea at first glance, but that doesn't mean it's not a good possible idea.  If you explain computers to soneone who has never seen a computer they will call you insane or a lier, but as we know computers are real.

Simply because something is unfathomable does not mean it is false. Now think, every letter you type here is 8 bits of information, and modern computers hold billions of those. All stored on silicon chips. Carbon nanotubes prevent the square cube effect to not take place on the cable. But the energy cost would be enormous, and as Weatherwax said, We as humans are not designed to work together like that. Its not our nature.

Sad but true.

Misero: PLEASE repeat that, but this time  in English cos we don't speak Gibberish, you maniac...

Space-elevators; COME ON, FFS!!!

I understood it perfectly fine. Maybe its just your level of education that's holding you back.

Please tell us why you think space elevators could not work.

Why don't we have space elevators all over the place, if it is as simple as you claim it is.

Well, they would currently be pretty useless and cost very much.

Well, we must have been there first to set up an elevator. Why do we need to go to the moon? Also, the motor to control the cable would have to be powered by the moon, because a wire could not transmit electricity that high, it would all disperse. The problem with generating coal or oil energy on the moon is no air for fire. And why would we use our limited water for electricity? We could use solar, but then as soon as it gets dark on the moon, the rope will go slack, likely killing some people. Nuclear is out of the question, as it requires huge amounts of water(which is hard to get to the moon) and uranium(which is decently hard to get to the moon).

Space elevators are yet another one of those cases where the concept is fairly simple, but the implementation is exceedingly difficult.  Right now, the biggest single problem is developing a material that is strong enough, yet light enough, to make the cable out of.

In theory, Carbon Nanotubes would work.

Yeah, but you need Bruce Wayne or Tony Stark to pay for them.

And the actual construction of the elevator until it could sustain its height would be borderline impossible with current technology.

Lemmiwinks: As I've helped construct plenty of elevator shafts, my level of education on the subject is just fine.

Even small, 5 or 6 storey, ones contained many hundreds of tons of concrete & steel.

Have fun getting that lot up to space!

But sorry: carbon nanotubes, geostationary orbits, lunar tethers, laser-blasters, blah, blah, etc...

It's my own fault I guess; I just don't get it, do I?

Being stuck in reality, as I am...

ROFL!!!

So you deny every carbon nanotube material is not made of carbon nanotubes? Wow. My bicycle seat must be made or aether.

Umm...  Are you thinking maybe carbon fiber instead of nanotube?  I didn't realize that nanotubes were actually in mass production yet.

because of the rotation of the Earth and the counterweight at the end of the space elevator the whole structure would actually be under tensile stress because of how the elevator leads to geostationary orbit and just beyond that there is a counterweight which produces an upward force because beyond geostationary orbit a 24 hour orbital period is too fast for a circular orbit.

They're not. There have just been carbon nanotube bicycle seat. I wasn't saying that I have one. Sort of a joke.

Obviously not a very good one.  Keep trying.

If it was not very good, why did you fall for it?
