In retrospect, with so many moon-hoaxers around, it's probably a good thing they didn't do this. -- Joseph Nebus -------------------------------------------------------------------------- ---- |

Ahh if some minor component fails I will restart this discussion. morale is definetely important but currently the station is in emergency mode without shuttle supplies Great. So, please come up with the exact right 5kg or so of "right components" they'll need. It's a big station. Make sure you pick the right ones, since I'd hate to see what would happen if you spent 5 kg of mass for one set of items only to find out the failed component wasn't among that list. HAVE A GREAT DAY! |

The Soyuz U2 vehicle (the one that used Sintin) did have slightly higher
performance than the standard Soyuz-U, but this performance gap was erased with the introduction of the Soyuz-FG, which uses higher performance engines in the first and second stages. The next version of Soyuz will use a better third stage engine, and replace the analog flight computer with a digital system, and so will have significantly better performance. "Christopher M.

Hmmm... I was under the impression that the Soyuz had lower performance now than it used to, as the Soviets used to use Sintin rather than stock Kerosene. The Russians ran out of money to keep Sintin production running sometime in the mid '90s. |

Note that the mass for the reworked Soyuz heat shield is no more than 300
kg. Updated details about the Lunar Express SM system are available at: www.constellationservices.com but if you can read Russian, there is a very interesting story at: http://www.kp.ru/daily/23335/31058/ BTW, I would be happy to answer questions about this near term lunar mission, right here. DWA "hop" wrote in message om... "Jim Oberg" wrote in message ... FYI: A very handsome 50-page brochure (Russian and English) about Progress M50 and background can be downloaded in pdf form from http://www.federalspace.ru/video/Progress_M50_www.pdf Specific mission details (in Russian) can be read at http://www.federalspace.ru/Start1Show.asp?STARTID=574 JimO www.jamesoberg.com Nice find. Far more interesting than the fact the ISS crew get magazines and DVDs to me was the Soyuz LV upgrade timeline. While the aurora/onega stuff seems likely to be viewgraph engineering, the Soyuz 2A and 2B and perhaps the Kourou pad seem to be fairly firm. Anyone know if this is true, or just more 'if we had the money' dreaming ? Incidently, the Soyouz 2B gives an extra 1000kg to LEO from Baikonur, which should be plenty for extra heat sheild that the seemingly implausible CSI http://www.constellationservices.com/ plan would require. Hmmm... It is also interesting to see the same LV gets about 2.5x the payload to geostationary from Kourou compaired Baikonur. That should provide an attractive option for medium sized GEO sats. |

DWA Nice to see you here. There was some discussion of the concept earlier on this NG (see this long url for google archive http://groups.google.com/groups?dq=&hl=en&lr=&ie=UTF-8&safe=off&threadm=64c0d119.0408060844.261c9825%40 posting.google.com&prev=/groups%3Fdq%3D%26num%3D25%26hl%3Den%26lr%3D%26ie%3 DUTF-8%26group%3Dsci.space.station%26safe%3Doff%26start %3D25 ) My personal take is it is a very interesting, but it would be hard to get anyone to pay for it. The US Govt. won't, because of the Iran non-proliferation act, and the fact that 'buy cheap Russian hardware' is not likely an acceptable component of the moon plan (for both good and bad reasons). If transportation of humans and cargo to lunar orbit were open for anyone to bid on, it could be a different story. ESA might, conceivably, but it is hard to see how they would justify it. ESA ISS flights are promoted as providing manned spaceflight experience (since they fly as FEs) as well as micro-g science. Neither of those would seem to gain additional benefit from going around the moon. National prestige alone seems questionable, especially if they are just paying for a ride that anyone with enough cash can take. Tourists are possible, but the cost would seem put severe limits on the market. At the current $10-20 million rumored price, the Russians still have some trouble getting applicants who have funding and can meet the medical and training requirements. Even if the boost stage (+ECLS and hab area) could be made largely by gluing together existing hardware, it is still a new manned spacecraft. And even though the Soyuz upgrade should be reasonably simple, it would require some development and re-qualification. Zond was a long time ago, on a different LV, and a variant of Soyuz quite different from the TMA. All this makes me think that the development cost would be non-trivial. In any case, I wish you the best of luck and would be glad to be proven wrong. |
