Gaetanomarano, the full report on the ESAS is now available on-line. It lays out how the whole system will work, in detail, from launch abort tests, to Earth orbit, the Moon, and even some very interesting facts about Mars missions. It also reveals why the various elements of the system were chosen; why this engine, why that shape, and why others were not used. The whole program, from now to Mars, is a system where each piece is considered in its relationship to the whole scheme. <br /><br />This report is long, and it has a lot of acronyms. I do respect the fact that you are dealing with a tough language (English), but if you really care about the exploration of space, it would be worth your time to try to read this report. <br /><br />This report was not put together by politicians, although the engineers and scientists who wrote it knew that politics, money, and technology were all factors in how this system would be received. I believe they did a very good job. <br /><br />We all have things that we would like to see happen in space, someday. I have my own list, and some of it is definitely in the realm of science fiction. But, here in the real world, we have to deal with tough realities, and this report is how the United States proposes to accomplish space exploration for real during the next few decades, using limited funds and limited political will to achieve quite a lot. <br /><br />If you are not willing to acquire some good knowledge about the system you so constantly attack, you simply label yourself as just another crackpot. That word means "a person with crazy ideas that have no basis in reality" Gaetanomarano, and that word is already being used on other forums to describe you. <br /><br />Please. Take a break from the constant posting and read the ESAS report.
