You seem to be more abreast with the technology than I am. However, from my reading, I get the impression that the current Ares program is primarily designed to keep ATK in business making solid fuel boosters.I like the DIRECT idea. However, I would modify it by swapping as far as possible the SSMEs for RS-68s. The SSMEs are expensive, but they are reused. None of the DIRECT hardware is, so cheaper, one-use only parts should be substituted. One thing I don’t understand, and I have never seen any references, is what does it take to human rate a launch vehicle? I have seen many articles citing the cost of uprating the Atlas/Titan/Centaur vehicles, but no-one seems to know what it entails. |
