(Derek Lyons) : There probably isn't a single company in the world that can do the job, nor a consortium of the either. You are seriously delusional as to how complex a 'simple' taxi/lifeboat is. No, I am not. Yes, you are. The mere statement that you think that Rutan or anyone else can do so 'in two years' is shining proof of just that. I am quite aware how stupidly complex NASA or the ESA can make such a craft. Ignorant bigotry. (As Henry pointed out - It took NASA much longer than two years to fly the Gemini, and that was back in it's glory days *and* with a spacecraft considerably less sophisticated and capable than Soyuz.) However if you had read the lifeboats in space thread you would realize a simple float untill rescue lifeboat does not need to be complex. However, if you read this thread, you would realize we are talking about a Soyuz replacement, not a (hypothetical and non-existent) craft that can float around until rescued by (also hypothetical and non-existent) another craft. (And given that maritime lifeboats for hostile enviroments are neither simple, nor cheap, one wonders about your conclusions regarding space ones. It's *hard* to make things that must wait quiescent for extended periods, and then function with no checkout and a near guarantee of sucess.) D. -- Touch-twice life. Eat. Drink.

![]() "Jim Oberg" Space station future adrift By Philip Chien 27 November 2004 // SPECIAL TO THE WASHINGTON TIMES Thanks for the interesting post. Chien restates a situation that the Russians have been calmly reminding NASA about from time to time. In the event that Shuttle remained grounded, RSA has said that it would have to reconsider the nature of its ISS operations, which I took to mean that it would essentially became the Russian Space Station. Even when US funds were being sent to RSA, there were bureaucratic malfunctions. Cash went from NASA to the Russian treasury and never made it all the way to RSA. Arrangements were later made for direct payments. I think that Russia has been diligent in its work on Soyuz because of the not inconsiderable number of flight made by the Shuttle to the Mir station. But it seems that the Russians have now paid off their account. The Iranians aren't helping things at all on this front. While they have apparently given some sort of agreement not to produce weapons-grade uranium, they still operate a 40 MW plutonium production reactor. The upside to this, such as it is, is that it takes longer to produce a plutonium bomb than a uranium bomb, buying the diplomats a few years of breathing space. The downside is that the plutonium bombs fit better on top of intermediate-range ballistic missiles. K. |

![]() "Charles Buckley" . And, when it comes to China, until we reach an agreement with them concerning the exchange rate, don't expect much cooperation between the governments on governmental projects. It look to me like the banking community can tolerate US trade deficits or budget deficits, but not both. China has been forced to issue lots of yuan in order to buy up all the dollars that they have coming in. And then they use the dollars to buy our public debt. It may turn out that by the time the Chinese get around to re-valuing the yuan, it won't be necessary. The yuan is a bargain at the current artificial rate, but as the dollar falls it will stop being a bargain and will arrive at its fair value, at least from the US perspective. It will still be cheap to Japanese and Euro buyers. I don't understand all the complexities of the banking business, but it is obvious that if foreign investors withdraw capital from a particular region, the economy there suffers for it. (Higher interest rates would slow the economy for one thing.) Here is a recent survey of the situation. ------- Foreign Interest Appears to Flag as Dollar Falls By EDMUND L. ANDREWS NY Times Published: November 27, 2004 WASHINGTON, Nov. 26 - Investors and market analysts are increasingly worried that the last big source of support for the American dollar - heavy buying by foreign central banks - is fading. The anxiety was on full display Friday, when the dollar abruptly slid to a record low against the euro after a report suggesting that the Chinese central bank might start to reduce its holdings in the American currency. Though Chinese officials later denied the report, and the dollar recovered, analysts say the broader trend is that foreign governments are becoming less willing to finance the growing debt of the United States government. On Tuesday, a top official with the Russian central bank said his government had become worried about the sinking value of the dollar and might switch some foreign reserves to euros. A day later, India's central bank hinted that it was worried about the same issue and might shift some reserves into other currencies. Japan and China, which together have amassed nearly $900 billion in United States Treasury securities, have both slowed their buying sharply from the frenetic pace in February and March. "There is an emerging consensus that banks around the world are moving to expand their reserves of euros at the expense of dollars," said Laidi Ashraf, chief currency analyst at MG Financial Group in New York. The Bush administration has essentially condoned the dollar's decline. At meetings with foreign ministers last week, the Treasury secretary, John W. Snow, repeated the American mantra of support for a "strong dollar" but also for letting "market forces" determine exchange rates. A continued decline of the dollar would be good for American manufacturers, because it would make exports cheaper in foreign markets and push up the cost of imports. But a diminished foreign appetite for dollars could push up interest rates. The Federal Reserve has already raised short-term rates four times this year, but the shift in the sentiment of foreign investors may soon seriously affect long-term rates that influence the cost of home mortgages. "Sell U.S., buy Europe," summed up Richard Berner, chief United States economist at Morgan Stanley, in a report last week. Mr. Berner noted that investors have begun demanding higher yields for 10-year Treasury securities than for comparable European bonds, and he predicted that the spread would widen. Recent data from the Treasury Department indicated that foreign governments had sharply slowed their purchases of Treasury securities. The question is whether those purchases will continue to slow or start to increase again as countries try to shore up the American currency to help maintain their own industries' competitiveness. Japanese purchases of Treasury securities, which ballooned by about $100 billion from October 2003 to March of this year, have slowed sharply and actually declined slightly in September. Largely as a result, the dollar has sunk to its lowest level against the Japanese yen, about 102.5 yen to the dollar on Friday, in four and a half years. Chinese purchases of Treasury securities slowed to a crawl, increasing just $2 billion in September, to $174 billion. On Friday, a top Chinese central bank official denied reports in a Chinese newspaper that the government planned to reduce its holdings of Treasury bonds. But Chinese officials, under prodding from the Bush administration, have repeatedly said they want to gradually relax their 10-year-old policy of locking its currency, the yuan, at a fixed exchange rate to the dollar. Any move to a more flexible exchange rate for China would probably cause the dollar to drop in value and allow the Chinese central bank to stop buying United States debt securities. America's current account deficit, the broadest measure of its indebtedness to other countries, is on track to exceed $600 billion next year, about 6 percent of its gross domestic product. The United States needs to attract about $2 billion a day to keep its spending at current levels. The nation attracted enormous sums of foreign money in the late 1990's as well, but the character of that money has changed. Back then, a big part of the inflow was through foreign direct investment and purchases of American stocks. This year, by contrast, foreigners have been net sellers of stocks. The big growth has been in foreign purchases of Treasury securities, and the big buyers have been foreign central banks that wanted to prevent their own currencies from rising too much against the dollar. Tony Norfield, currency strategist for ABN Amro in London, said he was convinced that central banks were trying to scale back their purchase of dollar assets, a move that could push the euro, already up about 30 percent in the last years, even higher. "You do not need the central banks to sell Treasuries for the dollar to go down," Mr. Norfield said. "All they have to do is buy less and the dollar is going to be in trouble." The euro hit a new high of $1.3329 on Friday in light trading, before settling back about a half-penny. European leaders are alarmed about the potential damage of a sinking dollar to their exports. "Recent moves on exchange markets of the dollar versus the euro are unwelcome," said Jean-Claude Trichet, president of the European Central Bank, at a banking seminar on Friday in Rio de Janeiro. "I want to underline the importance of recent statements by the Treasury secretary of the United States on his determination to pursue a strong dollar policy," Mr. Trichet added. But Mr. Snow and Alan Greenspan, the chairman of the Federal Reserve, offered no hint that they would intervene in currency markets to prop up the dollar. "The market for U.S. Treasury securities is deep and liquid and continues to be attractive to a broad and diverse pool of investors," a spokesman for Mr. Snow, Robert Nichols, said. That remains to be seen. According to the most recent Treasury data, the biggest source of growth in securities came not from China, Japan or Europe but from Caribbean banking centers. |

job, nor a consortium of the either. You are seriously delusional as to how complex a 'simple' taxi/lifeboat is. Ahh, you add the word "taxi". If you just say "lifeboat", then it greatly simplifies things. Undock with enough spring to get you far enough away, then a couple of thrusters to orient, and de-orbit engine, the rest is re-entry, parachutes, and maybe some retro rockets for final metre of descent. Something the size of Rutan's Spaceship one is fine (just put enough of them on station to cover crewing needs). Because you're not launching, avionics need not be so complex. And in terms of redundancy, you don't need systems as complex as the shuttle's. De-orbit isn't as millisecond critical as ascent. You need to get right orientation, burn de=orbit engine for X seconds, deploy parachutes, and then fire retro rocklets for landing. (or heck, just inflate some large that deploys like ain a car and deflates after first impact). t doesn't need to be re-usable. It doesn't need fancy life support if the max time you'll spend in it is 2.5 hours. (1 orbit max and 1 hour minutes to fall down.) Goal is to get you back to earth safely. The earliest you decide when you de=orbit, the fastest they can send rescue helicopters to your area. If you design a 1 or 2 person thing that can deorbit and bring someon to the ground, it doesn't need to be complex. If you design it so that it can also be used for expedition to mars, haul 15 tonnes to Jupiter, land at any airport and carry 6 passengers for 3 weeks, then yes, it will have to be very complex. |

a cash-strapped Russia wants compensation for building more of the spacecraft after 2006. Correction. 'Capitalist' Russia, NOT 'cash-strapped' Russia. If it's 'cash-strapped', then the same can be said to N.A.S.A. and even the U.S.A. Well... Political issues aside (considering that the U.S.A., the Russia federation, the P.R.C., and so on are run by the same group) the actual question is, is I.S.S. still going to be use after the 11th Soyuz? If yes, then more Soyuz or what ever vehicle will be supplied. How to do it is up to the people involved to decide the way. If not, then just use the I.S.S. without a lifeboat or abandon the I.S.S. What? Abandon the I.S.S.? Why not? Mir obviously is scrapped that easily, despite its historical nature, its capability, and so on. But of course, one of the primary reasons on why Mir was scrapped it was because it symbolize the superiority of the U.S.S.R. This I.S.S. without a lifeboat thing is intentionally overblown with the intention to terrorize people. |

Tyere are a great many countries that have nuclear reactors and programmes. The USA is far from having some sort of monopoly on this. Brasil refuses IAEA inspectors in some of its facilities, claiming it has proprietary technology. Yet, you don't hear the USA threathetning to invade Brasil. Canad has developped its own nuclear technology, very different from the proprietary USA nukular technology. When Edison invented electricity, he had a monopoly on how to generate it. But today, every country in the world knows how to make it. Same for nuclear. It isn't some black magic. Perhaps there are reasons for this difference in perception of Brazil's and Iran's nuclear programs. Brazil's parliament does not ritually chant "Death to America". Brazil does not support active terrorist organizations. Et cetera. |

Maybe Russia's Space tourists will get to ride up or down on the Shuttle so the Soyuz can stay at the space station for six months. Although it would increase the risk that the tourist would have to be willing to take, riding on two vehicles might actually increase sales on there infant space tourist bussiness. I wonder if that new space tourist law was passed? That would be really ironic if NASA was the first to limit their liability with the new law that was ment to foster private space travel.

Actually, they wouldn't have to fly on the Shuttle. NASA could just encourage Russian to commit to flying two tourist flights per year. Kind of like what they have already done twice. Craig Fink |

Why do you say that? Ummm...because it's true. NASA is not subject to regulation by any other government agency. Yeah, that's true, and the government is immune to liability except where it chooses not to be. |
