The Space Frontier Foundation has gotten a lot of attention from the mainstream press with their latest Whitepaper.
They advocate a more extensive support fo free enterprise and entrepreneurship in the American space program. They suggest that NASA should no longer be allowed to develop and own new launch vehicles, and that CEV and CLV development should be cancelled. They also advise that NASA rely on Altas 5 and Delta 4 rockets, and transfer more funding to the Commercial Orbital Transportation Services program. I cannot find the actual white paper on the SFF website. I don't know if SFF is particularly professional (certainly their gaudy website doesn't look it), but I have to agree with some of their points. |

UDMH is both toxic and carcinogenic. It's been a big concern in Kazakhstan for some time now, and Russia is developing the Kerosene/LOX Angara first stage as a replacement for the Proton. When spent rocket stages from Baikonur fall to Earth, the local residents rush out and begin cutting them up to sell the titanium scrap metal. Children play in the wreckage, herds of farm animals die mysteriously. You also get considerable contamination around the launch site, because combustion is not perfect during startup. [attachment=6930:attachment] [attachment=6931:attachment] Titan II was an ICBM developed in 1959, and hastily pressed into service as a manned launcher when the space race first began. The Ariane 1 also used this fuel, but it was developed with extensive Soviet assistance -- they even supplied UDMH to France. But for a country to use this technology for manned flight in 2006 is not very advanced. |
