This thread is established for the discussion of Virgin Galactic http://www.bbc.com/news/science-environment-35002459 i don't think this is new, but i guess its now formal that they are going to use 747 for a launch platform. My critique here is that in that class the 777 is a better choice, given that it has a slightly higher flight ceiling and is less cistly to get to that altitude and back.

So, I have a predicament. I have been playing KSP which I have owned for a while and although I only got about 20 hours under my belt since the Early Access days (don't really have time to play games) I have gotten back into it. Well, I inadvertently launched a test orbital ship into space with enough power to break Kerbin orbit and enter into what appears to be a stable elongated orbit of the sun (read it all as it goes down here: Anyways, as I plan my rescue and refine my space program abilities (we only just achieved Kerbin orbital capabilities last night!) I realized that to attempt

This day in history. 1921 - Goddard begins liquid rocket experiments. - . Nation: USA. Related Persons: Goddard. Robert H. Goddard experimented with liquid oxygen and various liquid hydrocarbons, including gasoline and liquid propane as well as ether, as rocket fuel, under a grant by Clark University. He concluded that although oxygen and hydrogen possessed the greatest heat energy per unit mass, that liquid oxygen and liquid methane offered greatest heat value of combinations which could be used without considerable difficulty. But, he said, "the most practical combination appears to be
