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.'"
I can just see it...
Spaceship successfully launched!
OK, guys, who wants to work on the reentry system now?
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.
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.
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.
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.
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.
Look at how many orbital launch failures SpaceX experienced. The failures are not due to incorrect science but rather inadequate application of engineering.
As I understand it, SpaceX have built a new rocket engine and two new launchers and a capsule and flown them into space for about the same as NASA spent to put a dummy upper stage on a shuttle SRB and fire it into the ocean.
