Tycho Deep Space: a DIY, Open Source, Manned Spacecraft
misterbarnacles writes "Can space travel be democratized? Kristian von Bengtson and Copenhagen Suborbitals think so, and they're building a DIY manned suborbital spacecraft to prove it. 'Bengtson describes the craft as "a half sized Apollo-shaped space capsule with a diameter of 2 meters capable of serving one (or two) persons." When complete, Bengtson hopes the suborbital craft will convey a human passenger higher than 62 miles above sea level, allowing him the rare opportunity to escape Earth’s bonds and view the heavens from the ionosphere.'"
So I can send my first post to aliens?
To offset political mods, replace Flamebait with Insightful.
I can just see it...
Spaceship successfully launched!
OK, guys, who wants to work on the reentry system now?
I hope they are using open source techniques and machinery to build it - otherwise it will be 'closed source' tainted.
Does this mean that after he's built it, everyone else gets to vote for who flies in it?
Its not going up that worrys me, its the coming down.
They have a video of a test flight with a crash dummy in it. It is both awe inspiring and terrifying as the test dumy was pretty much shaken to death before having it's head caved in on landing.
As long as launching capabilities are only within reach of governments and mega-corporations, which are the only ones that can afford to use this spacecraft, this is a useless waste of engineering efforts by volunteers. The rest of the 99.999999% of us will never get a chance to fly in one.
I would be much more interested in an opensource electric car design.
I'll stick with Kerbal Space Program

Well that wouldn't be a suborbital flight. But this could be:

That's the difference between SpaceShipOne, a 747 and a kid on a trampoline.

I'm all for crazy ideas, and I'm a huge fan of space flight (just ask any of my friends, I drive them up the wall with it), but this has to be the worst idea I've ever seen.
Sig: I stole this sig.

...that can be replicated using a 3d printer 3d printer
They are still traveling through 'space'.
so are we weightless long enough to have zero-g sex ?
The rest is just bookkeeping.

...suborbital means you've essentially escaped the Earth's atmosphere, but gravity is certainly gonna pull you back unless you reach orbital velocity. If you want to truly "escape Earth's bonds," you have to reach escape velocity.
62 miles up is barely worthy of space travel. It just goes up then quickly goes down. The difficult part of space travel, and why it costs so much money, is to be able to orbit the earth. If you want to leave earth gravity, you will need even more speed to get past earth escape velocity. It then costs a whole lot more. I double private company can do it much cheaper.
Did a documentary on this a few years ago...

I do not think that word means what you want it to mean.
deleting the extra space after periods so i can stay relevant, yeah.
I'm travelling through space right now, sitting in my cublcle.
That doesn't make it a spaceship, and it doesn't mean I'm NOT travelling through space.
It's pretty much all relative, eh?
deleting the extra space after periods so i can stay relevant, yeah.
What about all the junk and debris that might result?
You know, flicked cigarettes, empty soda cans, charred human remains...
Not to mention that satellites can be regarded as munitions. What if the Iranians want to let their citizens participate in recreational orbital flights?
Who will be first to join!?
These folk have the DIY, Open Source, and Spacecraft parts down pat. They haven't done much with the 'Manned' part, however.
Tiller's Rule: Never use a word in written form that you've only heard and never read. You will end up looking foolish.
Yes, it is really freaking hard, and yes it is really freaking expensive, and yes it's really freaking dangerous and probably downright defiant in the face of reason, logic and safety.... ....but IMHO, if we are ever going to colonize space, we need every attempt possible!
We need to get to the point where anybody can get to space, and STAY out there, and survive in unbelievable, unbearable conditions, with unbelievable challenges, to explore the unknown and dedicate their lives to space exploration OFF of this planet, in addition to everything else we already do.
If we want the universe to be our sandbox, we must evolve into a space-faring and space-surviving species.
Imagine where we would be if a lot of people hadn't pushed the limits beyond everything we could imagine, and yes.... even died trying to accomplish manned flight.
I'm curious. What exactly is 'closed source' about building a car, or an electric car? All you require to build one is tools, materials, skill and knowledge.
This is a DIY project that I would love to see more of. I just hope that in my lifetime I would be able to witness amateur space flights that are "built in the back yard" so to speak. Its a throw back to early oceanic exploration. There will be accidents and possible loss of life but hopefully that will be quite rare.
I just hope they are good with vacuum leak detection. They should have a helium mass-spectrometer leak detector, pressurize the craft with a mixture of helium and some other inert gas and sniff for leaks. Once you work with vacuum, you quickly learn that sealing a closed system to atmosphere can be a tricky business. And that is even more apparent when the vessel undergoes thermal expansion and contraction which loosens otherwise tight seals. Lots of good tig welding is needed along with electron beam or laser welding for more intricate parts.
Imagine the opportunity for engineers and students if amateur space exploration ever gets off the ground (pun intended!). I cant wait for the day when garage hot rodding turns skyward.
They've already solved this problem ;) http://www.wired.com/wiredscience/2011/12/so-you-got-a-space-rocket-but-nowhere-to-launch-it/
Really? Someone hasn't read up on Marathon... http://marathongame.wikia.com/wiki/Tycho
Or maybe they have...
I'm pretty sure they do their own launches too. Aren't these the ones that built their own rocket and launch platform on a boat?
Check out their first attempt, the Tycho Brahe-1 . I wonder where they sourced the Imipolex G needed to construct the S-GerÃt .
the preceding comment is my own and in no way reflects the opinion of the Joint Chiefs of Staff
I live in Denmark, and the one of the guys working on this rocket came to visit our school to talk about it, and stuff. Well, I asked them what they meant by calling it opensource. It turned out, that it's only opensource as long as you pay them a visit, and look at how it's made. You can't actually download papers describing any of the mechanics in it. Apparently this was due to concerns on it being misused. He also told that one of the first to pay them a visit when starting this project, was PET (politiets efterretningstjeneste), which translated is something like "The police intelligence bureau".
This is what I don't get about the manned space program. Yes, having people up there is cool. It would be awesome to leave the planet and go populate others at some point if only as an exercise in preservation of our species while we determine what exactly we stand for that's worth preserving in the grand scale of things. However, at the current moment we have no working method of shielding a craft (and the individual inside) from charged particles and cosmic rays.
Yeah it's a great view and all, but personally until we get some basic shielding functional I'll keep as much atmosphere as possible between myself and the chaotic high energy quantum world beyond it. Especially with the sun as active as it is now.
You don't get the design plans, let alone permission to modify and distribute them. You can also decompile and figure out how a program works, you have all the tools. It is just insanely hard.
I'm traveling through space *and* time.
Democratized space junk?
The abstract makes me imagine.. you know how people book out time on the telescopes in Arizona, Now all the cool kids go on NewEgg and buy a couple of NBPs running NetBSD! shoot it out unplug the house mic and let 'er go! Build some contraptions that shoot pictures and the (within tolerances) direction / attitude / vector / rotation you want the contraption disembarked at, load them up on a public space shuttle deal and a company could disperse them into space from on board. Hmm! And of course the contraptions run NetBSD! lol They could take pictures, and imagine the delight as the customer's latency increased as they plunged farther and farther into the outer reaches! And if it gets lots whoops! The point is it rocked! They could guide their selves with some onboard compressed air and solar action too. Excellent, it really is 2011 isn't it!
Just like in the software world. I don't have the code or distribution permissions for Windows or any other commercial OS. This doesn't stop Linux from existing.
Why is it any different for cars? There is nothing to stop you building your own (And lots of people do).
