Can Russia invite China to ISS?
LooseChanj wrote in
m: On or about 18 Oct 2003 19:25:43 GMT, Jorge R. Frank made the sensational claim that: Or to spite China. India and China are rivals, too... just read India's press reaction to Shenzhou 5. Link? It was an editorial in the Times of India on the day of launch, calling it a "stunt" or a "joke", linked to by spacetoday.net. Oddly, I can't seem to find the actual story from either site now, nor from Google. There are other articles linked from spacetoday.net that make a point of contrasting India's peaceful space program with China's military-run program. That's to be expected, of course. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |

Can Russia invite China to ISS?
"Explorer8939" wrote in message om... Chris Bennetts wrote in message ... IIRC, Shenzhou's docking equipment is APAS, so that would require use of the US-owned PMA-2 (PMA-3 is currently unusable, and also US-owned) as a docking location, since their aren't any suitable ports on the Russian side. This is actually not true. The Russian Segment Service Module zenith port is hybrid, which is field replaceable by an APAS (meaning that the current cone adaptor could be changed out - on orbit - into a functional APAS. It isn't suitable "out of the box". I read some of the overviews of the work required to adapt Zarya's aft port to APAS, back when flying 2A.3 with the ICM was a real possibility. The work involved wasn't easy, though it was certainly possible if there wasn't any other option. Docking to the US segment would be by far the easier option. In any case, I'm sure that Russia would prefer to keep Zvezda's zenith port free so that they can relocate DC-1 there sometime in the future if they can find enough money for the SPP. --Chris |

From the chinese launch site can they even reach iSS with their available hardware? |

Is it really APAS? As of yet, no Shenzhou has had an APAS on the top of the orbital module. At least I've not seen a picture of this. I've only seen a picture of a Chinese space station mockup that appeared to have APAS hardware at one end. At any rate, if it is APAS, China could possibly convert it to HP&D for an ISS flight. This would seem to be easier than converting an HP&D port on ISS to APAS. This would allow docking to the Russian side of ISS, in case the US didn't want Shenzhou docking to a PMA.

There are 2 questions he
1) Do the Chinese really have APAS docking systems? Yes, they do. The Russians sold the Chinese APAS and some other systems useful for Shenzhou missions. 2) Would it be easier for the Chinese to use Hybrid on Zhenzhou to dock the with Service Module Zenith Port rather than convert that port to APAS? Assuming that the Russians were in the mood the sell the Chinese Hybrid docking adaptors, yes. But it is not clear whether the Russians really want to release Probe and Cone (even the Hybrid variant) to someone else at this time, it is a much more useful and valuable system than APAS. jeff findley wrote in message ...

Jorge R. Frank a écrit dans le message : ... Ben Sisko wrote in : ISS partners would demand that China first demonstrate that its systems are reliable enough to perform safe docking. This means China will have to do its own dockings with its own equipment a few times. The ISS partners would be on very shaky ground if they demanded a more rigorous testing program for Shenzhou than is currently being done with ESA's ATV and Japan's HTV. I don't know about HTV, but ATV is using the same russian docking mechanism as progress at least as far as the mechanical parts go, so this is quite validated. As for approach, the first ATV flight will carry a KURS as a redundant ( payload ) system, in order to validate the european system. There are also numerous redundancies and ground and crew checks in the system. I feel that for China to be allowed to dock on the USA side, it would require a diplomatic decision with the USA president telling NASA to allow China to dock, against NASA's objections. I find this ludicrous. The president is more likely to oppose a Chinese docking to ISS than NASA. And there would be sound US strategic reasons to let the Chinese dock to ISS, or even take them in as a partner. Even a one-shot docking would allow US experts their first good look at the inside of a Shenzhou. And if you think the US would consent to a Shenzhou docking without being allowed inside to inspect for hazardous materials, think again. Shenzhou is Very true. NASA safety review boards are examining in details EVERYTHING about ATV, even things which, IMHO, should be considered company know-how secrets, such as navigation algorithms. I just hope this knowledge stays well isolated from US companies. |
