/sci/ - Science & Math

Because I'm using a Linux distribution on a powerpc.

Launched, crashed, uninstalled.

is it good? Tell me how good it is.

I didn't know it existed.

Tell me about it, and i might.

>>2352648
did you seriously just do something because a /sci/ told you to?

>>2352671
I have listened to /sci/ many times and it has actually enriched my life and my understanding of the universe.

Plus, this looks really cool.

Holy crap this looks pretty cool

>>2352701
Gah forgot picture

>>2352671
Did you really just become so disquieting by something on /sci/ that you bothered typing out a post regarding it?

>>2352650

This good

I am, and enjoying those fine mod.

Even if some aren't exactly realist it make it possible to test idea.

This is a real mode. And with it you can stress test the realism of 2001.

Or build your own space station with unlimited budget and a space shuttle fleet.

where can get?

How exactly does one build the space station? ._.

One piece at a time

Hello coffee

anyone wanna help me import my spaceship?
Here are the files
http://www.2shared.com/file/DCOuk9ts/Crew_exploration_vehicle.html

also I suck at piloting my spaceship

>Started on the moon using the Delta glider
>Got a vector to earth
>Going to fast
>Burn up in atmosphere

>>2353145

Kid, you're a high school junior. You should be out doing something fun. If you really need to import it into something, put into Microsoft Flight Sim X

>>2353152
And that makes my spaceship bad how?

and I don't have much of social life

>>2353165

>>2353145

Hey Scia, now that you're here, how do you add something into orbiter? I have the mesh right here ready to port it once I add some textures.

>>2353165
No idea thats why I was asking for help

Also if i remember right you have your space ship divided by large tethers

thats going to be a bitch to fly

>>2353169
How are you supposed to move left and right in the thing?

>>2353173

>No idea thats why I was asking for help

But you said:

>also I suck at piloting my spaceship

Did you port it to orbiter or what?

>>2353178

I dunno. Give the astronauts a tiny wire they can reel in or some shit.

Because it's fun when you're using the future space plane but then the learning curve is just too high when you try and use real ships.

>>2353181
I was using the Delta glider I said that

>>2353186

Nevermind.

>>2353183
If I remember thats supposed to fit 300 people

gonna require a lot to pull that in

>>2353188
Also coffee could i have the files for that spacecraft?

The physics suck ass. You can travel faster than the speed of light if you leave your ship accelerating for ages.

Found a thread on importing from SketchUp

http://www.orbiter-forum.com/showthread.php?p=203338

>>2353192

Actually this is just a standard Project Valkyrie spacecraft. I'm going to copy a few sections and base the 300-peep spacecraft off this model instead of working on both at the same time.

And you will have the files when I'm done texturing and shit.

>>2353203
Your not supposed to go to other star systems

>>2353165
>>2353169
You built that?

>>2353209
The chief feasibility issue of Valkyrie (or for any antimatter-beam drive) lies in its requirement of quantities of antimatter fuel measured in tons. Antimatter cannot be produced at an efficiency of more than 50% (that is to say, to produce one gram of antimatter requires twice as much energy as you would get from annihilating that gram with a gram of matter). Since a half a kilogram of antimatter would yield 9×1016 J if annihilated with an equal amount of matter,[3] this quickly adds up to enormous energy requirements for its production. To produce the 50 tons of antimatter Valkyrie would require 1.8×1022 J. This is the same amount of energy that the entire human race currently uses in about forty years.

Looks like an interstellar spacecraft to me

isn't orbiter only interplanetary

>>2353213
He took the idea from Project Valkyrie

But I think he modeled it himself

So what do you think of my spacecraft?

>>2353213

Yeah.

>>2353219

The Hius is also interstellar, but that won't stop me from using it just to dick around the Solar System.

>>2353229
Why just build an interplanetary spacecraft

like the ones from this page?
http://www.projectrho.com/rocket/realdesigns.php

>>2353237

Not epic enough.

Plus if in the future they decide to add another solar system, I will have the head start.

>>2353246
My spaceship is not Epic?

:(

>>2353255

>>2353229
Cool. My own Blender skills are limited to creating various boxes and extruding them into useless shapes. And losing them camera somewhere in the 3D space :-(

>>2353261
I though we were friends again?

>>2353259

Heh, the learning curve is automatic tho: Once I learned to extrude, resize and grab everything started to come along nicely.

However if I'm allowed to recommend something:

http://www.mediafire.com/?nxmzmwy3tex

>>2353264

Dude I'm kidding. There was no real reason to make one spacecraft or the other, I just picked Valkyrie because:

1- It's awesome.
2- It will be the first 3d render of Project Valkyrie and it might get me in contact with Charles Pellegrino (Yeah, in my dreams).

The idea of porting it into orbiter came later on.

>>2353210

It's not that it's the fact that firstly you can go faster than light and secondly no time dilation happens.

>>2353269
Maybe I will learn blender

Umm, does it have a tutorial that includes shit like controls rather than throwing technical jargon at you?

I tried to get through the first tutortial. It only explained why it was doing what it was going, but never what fucking button I press to do it.

>>2353272
Except you know that spaceship in Avatar

>>2353278

Ha! I knew you weren't the one who made the fire in blender!

I just had an idea for fixing or minimizing the problem of micrometeoroids and colliding into them at relativistic speeds, feel free to shoot it down.

Okay, it's like this. You have the craft for where you want to travel, but in front of it there are *insert number here* magnetic sheets one in front of another that produce a smaller magnetic force on their neighbour to push it away while being held by small metal cables so it doesn't just fall away. So when a small golfball hits at 0.2c it will first have to go through like 2,000 magnetic inertial plates before it can do damage. Or, more.

>>2353283

Shh.

>>2353272
>>2353272
So can we agree the first one who figures out how to import into Orbiter helps the other guy

No idea how you would do the string physics though

>>2353287

It's just like the mylar umbrellas of Valkyrie.

Except that those are just mylar umbrellas and not magnetic.

Then again even at 10% of c a golfball will do enough damage to turn the spacecraft into plasma. So you would have to jettison them and fire them ahead of the spacecraft once the acceleration period is complete.

>>2353286
No I was

I meant for CAD purposes

>>2353291

As long as the spacecraft is under thrust the tether will be taut.

When it isn't, well, I'm not going to make it wobble. I will make it rigid and tell the users to go fuck themselves.

>>2353287
How about we use Bigelow technology?

it uses material twice as strong as Kevlar

its stronger then the current ISS modules

>>2353291

>So can we agree the first one who figures out how to import into Orbiter helps the other guy

Ok.

>>2353303
You sure are a great engineer

>>2353309

Gee I'm sorry I don't know how to code this shit into Orbiter's physics engine.

My engineering instict tells me that if I let it wobble it will NEVER EVER fall back into place. I just know from having played orbiter for so many countless hours and watching the spacecraft spn above the ground or scratch the atmosphere and jump out at a few percentages of c.

>>2353307
also here is some tutorials for blender

http://www.blenderguru.com/

>>2353313
Then why not build a spaceship without a tether?

>>2353287
Congratulations, you invented the Whipple Shield. With the power of magnets.

>>2353319
You still there coffee?

pic kinda related - procedural galaxy

so is anyone excited about infinity the quest for earth? i cant wait for the planetary landfall demo.


inb4 vaporware

>>2353343
Yes i am im sad that they have not had an update since Tuesday, 04 May 2010

>>2353237
WOW
Those look so awesome.
Does anyone happen to know what was used to design them?

>>2353373
ask NASA

if only the United States took to space we could be space imperialists

Spreading democracy across the universe fuck yeah!

>>2353385
We must liberate these aliens from themselves!

>>2353408
I meant creating republics on the moon, mars, Titan, Ganymede, ect..

If we meet aliens I hope we act peacefully

>>2353319

Because Valkyrie has a tether?

>>2353586
Yours does

>>2354038

Nope.jpg

Charles Pellegrino designed it to have a tether. learn2antimatterpoweredinterstellarrelativisticsingleships

>>2354051
Im saying the spacecraft you designed has a tether

How am I wrong?

also I study interplanetary not interstellar

>>2354061
Also I was wondering what is the highest level on math that you have taken?

>>2354061

>Im saying the spacecraft you designed has a tether

And I'm saying all Valkyries have to have a tether Christ.

I thought this should be obvious given the huge antimatter engines a.k.a death ray bombs at either end.

>>2354154
It is obvious All im saying is that you should not import Valkyrie because of the failure of string physics

its not realistic bro

>>2353173
Actually that may be easier, no vibration, no need to compensate for the natural instability of pushing engine.

>>2353246
Doing actual shit on the planet and asteroid inside the system is better than putting insane effort for 10year of acceleration only interrupted by a turnover maneuver.

>>2353319
The point of this design is to save mass while protecting cargo from radiation, even at the interplanetary scale.

Also, I can count a few other practical use for it on an airless planet, most of them being "awesome air...void-drop operation"

bump

>>2353173
.... And I forgot to say : no twisting stress on the center of the structure if there isn't thruster all the way to the center of gravity.

The problem become worse if you have to do aerobraking / aircapture.
Though, that's something a Valkyrie design can't do, but that you can't do on any planet anyway.

>>2354253
Where is that picture from?

>>2352633

Becasue It only models Newtonian gravity. When they change the engine to reflect general relativity, I'll reinstall. And test my warp drive ship.

>>2354269
Don't you mean special relativity?

you know time dilation and all

>>2354291

General Relativity includes the postulates of special relativity. lrn2relativity

>>2354331
Ok then

>>2354291
>>2354331
>>2354339
PWNED!!!!!

>>2354269
Special Relativity won't matter if your "warp drive" isn't based on actual physics or bug in the program.

Also, you'll take less than a few second to go around the solar system.
