Missing module idea.
So, It occurred to me that with no down mass after Shuttle, things like
pumps etc, that fail will never be investigated. What there should be of course is a module with a large hatch which can be pressurised or not as the case may be, so eva crew could for example bring in large items like pumps and then pressurised the module for shirt sleeve investigations. Of course the gases in such modules woule need to be vented before one did this. Brian -- Brian Gaff - Note:- In order to reduce spam, any email without 'Brian Gaff' in the display name may be lost. Blind user, so no pictures please! |

Brian There is returnable payload on Soyuz, although only for small items; and in two years, Dragon will be operational. Any failed equipment can be stored until then. |

Most failed equipment won't fit in Soyuz or Dragon. The CMGs most prominently. Neither will the pump that failed last July. Brian's right that such a module would need a large hatch. External components have to be brought into the ISS first just to get to Soyuz or Dragon even if they did fit in them, but they won't fit through the airlock hatches. Brian |

"The maximum size of an item that can pass through this airlock is 576x830x800 mm" Or roughly two feet by three feet. http://iss.jaxa.jp/iss/kibo/al_e.html Worse case scenario, I guess they could depressurize node1 with all hatches closed to the station, open one of the CBM hatches to get something in, close it, and repressurise node 1. Never. Gonna. Happen. Is the outdoor hatch on Quest a larger diametre than the docking hatches on PMA1-2-3 ? Smaller. the PMA devices can be used as an airlock in a bind. Won't help. Brian |

Maybe the answer is one of these inflatable re-entry ideas with some kind of
deorbit pack which could be caried up externally by htv. Brian -- Brian Gaff - Note:- In order to reduce spam, any email without 'Brian Gaff' in the display name may be lost.
