Here is the scenario for commentary (history and strategy).
Shenzhou 5 has completed a successful mission, with Lt. Colonel Yang Liwei orbiting the Earth 14 times for 21 hours. You are the mission planner for the Shenzhou program and the program director has asked you for a list of the mission objectives for the follow-up flights. The Chinese leadership has publicly announced some specific long-term goals for the Chinese manned space program. These goals do not have specific timeframes. 1.) Earth orbiting space station 2.) Circum-lunar flight 3.) Landing upon moon You have a wealth of information from the earlier Russian and American manned and unmanned programs from which to draw comparisons and "lessons learned". For the Shenzhou program, name the flights (starting with Shenzhou 6), mission objectives and estimated timeframe. You can also name new or parallel programs to achieve additional objectives for achieving the recently stated manned space goals for China. G. Beat |

For the Shenzhou program, name the flights (starting with Shenzhou 6), mission objectives and estimated timeframe. You can also name new or parallel programs to achieve additional objectives for achieving the recently stated manned space goals for China. Well, the answer to this question depends greatly on the point of view that I take as "Shenzhou mission planner." Do I take the point of view of myself as a Western observer of the Chinese program, with my cultural baggage from the Cold War, or the point of view of a Chinese person, free (for the moment) of Cold War pressure from the US, and from a culture with a propensity to think long-term? Assuming the latter (and informed by advice from Asian friends, most of which tend to be Japanese or Taiwanese, so note biases), here is my plan. My additional assumption is funding for gradual ramp-up to 4-5 Shenzhou flights per year, and no ISS dockings (which, for this program, would be an unnecessary distraction). One more disclaimer: this is not my prediction of what *will* happen, just what *might* happen granted the assumptions above. Personally, I believe that the Western media reports of plans for manned Chinese lunar flights are based on mistranslation, and that their actual program will be geared more toward a Shenzhou-based mini-station. August 2004: Shenzhou 6 Crew: 3 Duration: 7 days First long-duration Shenzhou flight; stress-test of life-support system June 2005: Shenzhou 7 Crew: 2 Duration: 4 days Rendezvous (no docking) with the orbital module from Shenzhou 6. Shenzhou 7 orbital module contains core power/propulsion capability for Shenzhou station. March 2006: Shenzhou 8 Crew: 2 Duration: 4 days Rendezvous and docking with Shenzhou 7 orbital module. Shenzhou 7/8 orbital modules remain attached. Shenzhou 8 orbital module contains multiple berthing ports for future Shenzhou spacecraft. December 2006: Shenzhou 9 Crew: 3 Duration: 4 days Orbital module equipped with airlock. First EVA. No rendezvous/docking objectives. August 2007: Shenzhou 10 Crew: 3 Duration: 7 days Rendezvous/docking with Shenzhou 7/8 orbital module complex, Shenzhou 10 orbital module contains EVA airlock based on Shenzhou 9. EVA while docked. Initial operational capability of Shenzhou-based space station. Completion of objective 1. Unstated assumption from here on is that all Shenzhou orbital modules remain attached to Shenzhou station to augment its capabilities. March 2008: Shenzhou 11 Crew: 2 Duration: 45 days Rendezvous/docking with Shenzhou station. Shenzhou 11 orbital module contains additional life-support equipment. Long-duration life-support test. August/September 2008: Shenzhou 12 Crew: 3 Duration: 14 days Rendezvous/docking with Shenzhou station. 2008 Olympics PR flight. Possible inclusion of foreign guest yuhangyuan. March 2009: Shenzhou 13 Crew: 0 Duration: 4 days Automated rendezvous/docking test with Shenzhou station. Shenzhou 13 orbital module contains propellant/consumables tanks. Demonstration of in- orbit refueling (a la Progress-Salyut 6). August 2009: Shenzhou 14 Crew: 0 Duration: 7 days Automated rendezvous/docking (EOR) with upper stage previously launched by Long March 3 rocket. Boost to high elliptical orbit, undocking and re-entry to test uprated Shenzhou heat shield for lunar-return trajectory. December 2009: Shenzhou 15 Crew: 2 Duration: 90 days First long-duration Shenzhou station flight, taking advantage of consumables launched by Shenzhou 13. March 2010: Shenzhou 16 Crew: 1 Duration: 7 days Manned repeat of Shenzhou 14 flight. June 2010: Shenzhou 17 Crew: 2 Duration: 180 days Second long-duration Shenzhou station flight. Start of permanent occupation of Shenzhou station. September 2010: Shenzhou 18 Crew: 0 Duration: 4 days Resupply mission for Shenzhou 17. Demonstration of remote-piloting capability of Shenzhou 18 by Shenzhou 17 crew. November 2010: Shenzhou 19 Crew: 2 Duration: 4 days In-orbit checkout of Shenzhou lunar lander (in place of orbital module). December 2010: Shenzhou 20 Crew: 2 Duration: 180 days Third long duration Shenzhou station flight, replacement crew for Shenzhou 17. Orbital module contains additional supplies such that no resupply necessary. March 2011: Shenzhou 21 Crew: 2 Duration: 7 days EOR with previously-launched stage, manned circumlunar flight. Test version of Shenzhou lunar lander carried as emergency lifeboat. Completion of objective 2. June 2011: Shenzhou 22 Crew: 3 Duration: 180 days Fourth long duration Shenzhou station flight, first with three crewmembers. September 2011: Shenzhou 23 Crew: 3 Duration: 7 days EOR with previously-launched stage, manned lunar orbit flight. As with Shenzhou 21, lunar lander carried as emergency lifeboat.

Shenzhou 6, 2004: multi person, multi day mission
Shenzhou 7, late 2004: rendezvous with orbital module left in orbit by Shenzhou 6 Shenzhou 8, 2005: ISS rendezvous (no docking) Shenzhou 9, 2006: Dock with ISS, 6 day stay, return to Earth. Shenzhou 10, 2007: Dock with ISS, power down for 30 days, return to Earth Shenzhou 11, 2008: Dock with ISS, 90 day stay STS-131, 2008: Bring Chinese lab to ISS for berthing with PMA-2. etc, etc. No lunar missions in your lifetime for Shenzhou, sorry |

It depends on the engineered lifetime of the Shenzhou descent module. If the descent module is good for 180 days, Shenzhou 18 could leave just the orbital module as a station expansion. If the descent module is good for less, Shenzhou 18 would stay docked altogether as a lifeboat... and the rest of my schedule would be shot, since there would have to be an additional Shenzhou launch to the station every 90 days or so to change out the descent module lifeboat. That, in turn, would throw off the lunar landing date, since I scheduled it on a "non-interference" basis with a permanently manned station. Or the Chinese could simply not man the station full-time... For reference, the Soyuz Ferry was good for 90 days; the Soyuz TM and TMA for about 200. Such exercises help to illustrate how the timeline is dependent on assumptions. September 2013: Shenzhou 27 Crew: 3 Duration: 10 days Manned lunar landing, completion of objective 3.

made the sensational claim that: No lunar missions in your lifetime for Shenzhou, sorry Funny, I'd say the same thing about an ISS docking. Let alone multiple dockings. I think a fly-around of ISS by a Shenzou is a remote possibility, but I suspect there are better ways for reconnoitering the station without dealing with NASA or being so blatant as to approach the station without doing so. -- This is a siggy | To E-mail, do note | This space is for rent It's properly formatted | who you mean to reply-to | Inquire within if you No person, none, care | and it will reach me | Would like your ad here |

I agree; unless as part of some deal with China on some other issue, there's not going to be an ISS missions. Shenzhou probably isn't good for lunar landing, either, but circumlunar flight is almost trivial, assuming they have sufficient radiation shielding. The difficulties of lunar missions come with lunar orbit and landing, which require a lot of additional fuel and a lot of additional mass, which means you probably need a larger launch vehicle, etc. But circumlunar flight should be no problem.

The Skylab rescue Apollo was a backup to the lifeboat, not an alternative to the lifeboat. and originally the Shuttle was thought to offer rescue mission capability once operational. Yes, at a weekly flight rate, there would always have been one on the pad. The Chinese might decide on the rescue mission approach as an alternative to a lifeboat configuration. Or they might dispense with the notion of emergency descent/rescue altogether. I would consider that out-of-character for them, given the conservatism they've shown so far, and the low Shenzhou flight rate I'm assuming. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |
