Regarding to guidance: I heard one professor at my university saying something about some student building FOG gyroscope at home. Not easy task, I know, but obviously it can be done.

hmm. I somehow don't like calling these suborbital flights 'going to space'. They are not much practical. If you want to do some low-pressure, high-radiation and other experiments or just want to see spherical Earth than go for high-altitude ballon. Some company in UK (if I remember it...

I'm obtaining O2 from electrolyser. I'm using H2SO4 with water and tens of amperes (12V). I know what O2 is! And how dangerous it is, especially directly mixed with H2. I've already blown one elektroyzer on purpose as danger assessment test, so I practically know what I'm dealing with, not only...

lol

And using your value of 4g/s * 5kg, for 20s burn with 20L gas container.. the cont. has to withstand 30 atm. And with ~50atm rated container the rocket will weigh more than 5kg, not including other things... I know. But who says it have to be small rocket? :lol: Anyway, it would be...

Hydrogen can be replaced by kerosene.. leaving more room for oxygen. I know this very well. I blew up 10L plastic can once (filled with O2 and few ml of kerosene). Pretty loud bang...

Would it be possible to build H2 + O2 rocket using plastic bottles as storage for pressurized gases? I've been playing with this idea for a while now. It wouldn't be a problem to fill the bottles with the gases, although I don't even roughly know how many atm could ordinary plastic bottle...

It's quite funny that the cube test work for me only under wine. In WinXP the main texture of the cube is not visible (transparent). Yeah.. I have the most recent directcrap a nvidia drivers (7600GT). I'll make some screenshots from win. But here is one from wine: It's only orbiter base, DGIV...

I've tried Orbiter with latest OGLA in Wine under openSUSE and it worked. (had to disable some effects and use 'winetricks' to obtain some libraries). The biggest problem is that the orbiter doesn't respond to pressed keys. Simply, the keyboard focus is on window with OGLA (which can be...

If you are planning to ask Martin for the source code, ask him if he could release whole orbiter under MIT license.

hmm. I can't find orbiter beta thread in this new forum. could somebody give me a link pls?

Which driver do you use?

You must be kidding! AMD/ATi have very good drivers. One proprietary, and another one, fully open-source (and directly supported by AMD). Even the latest cards are supported in both "versions". They have also good opensource driver for openSolaris and Solaris based systems. AMD/ATi had have...

Getting of Venus may be much more easier than you've supposed. Filling special baloons with proper inert gas would take the ship or return module to great altitude where it's thinner atmosphere and where it could slowly enagage thrusters a speed up, then at certain speed release the baloons...

Linux is just KERNEL. Excelent, but only kernel. It's not operating system. GNU/Linux is type of operating system. I really don't know why majority of people call it Linux. Most of today's distros consists of parts from GNU project + a few own parts + Linux. It's like calling "whole human"...
