The Hydrogen Fallacy

Posted 01-31-2012 at 01:19 AM by T.Neo

(For the TL:DR version, scroll down to the bottom of the post.)

Here it is so far:



My first 3D model and first completely original Orbiter...thing. It'll get better. I hope.

In the mean time, I'm in the middle of the idea phase. Here's what I want it to do, at least for now:

Minecraft Portal map development

Posted 01-27-2012 at 08:36 PM by Samuel Edwards

It will act as a Dragon capsule alternative, and as a long duration capsule. The engine testing was to check that all components were running smoothly. We have launches planned to the ISS and Space Station Tranquility. Right now however, we will maintain continued use of the Dragon capsule. Continued tests,...
