Once the shuttle is flying, would it be possible to use the shuttle to return one of the completely failed Elektron units for refurbishment and reflight? What would be the sense of doing this? It's tossing good money after bad. Perhaps this could be done on an MPLM flight, since the MPLM gives you bigger hatches than you get through the docking adapter. Given that you have to go through an APAS hatch to get *to* the CBM hatch... There is no 'win' to using an MPLM so far as hatch size goes. OTOH, you do cut down on the handling.

One thing that I read said that part of the problem with the Elektron unit
is that they were pretty much hand-assembled one of a kind things, and that the guy that really knew how they worked has passed away "taking sone trade secrets with him". It may not just be a matter of replacing some parts to get them operational. Bryan |

Furthermore, ESA and Japan are a bit slow (in terms of the ISS
program) in getting their resupply ships operational. It clearly would have been beneficial to have thier ships flying by now as a backup to any Shuttle or Progress failure. This article: http://www.space.com/spacenews/busin...ay_040419.html just talks about technical and procurement problems. But wasn't there also something about the agreements between the partners? That ESA wasn't obligated to provide ATV until Columbus was launched, and therefore they delayed the Columbus launch. Or something like that? (This is kind of a dim memory, so I'm not sure whether it has any bearing on when ATV will start flying, or how often ATV will fly). |

Space station may fall into disrepair Michael Hopkin Failure to fix oxygen unit could leave orbiting lab crewless. YEAH! Lets dump that poor excuse for a station and ground the shuttles too before they ill another crew!!!! HAVE A GREAT DAY! You missed the entire point of the article. It was written with the only purpose to re-iterate that the problematic generator was _russian_ built. The rest is just bunch of largely meaningless sentences added for volume. The US has resumed its internal BS campaign intended to prepare the pull out of ISS program, blaming everything on the "international partners", and this article is nothing else than a small part of this campaign. I won't be surprised if this "Michael Hopkin" in reality this is the same person (or group of persons) who's responsible for producing the recent stream of BS in "Florida Today" and other similar nonsense. -- Best regards, Andrey Tarasevich |

Day 1: the sun rises in the east Day 2: the sun rises in the east Day 3: the sun rises in the east I predict that on Day 4 the sun will rise in the east. In the same vein: day 1: people predict russian calamity. it doesn't happen. day 2: poeple predict russian calamity, it doesn't happen. day 3: poeple predict russian calamity, it doesn't happen. I predict that the next call for russian calamity won't materialise and the station will continue to orbit and keep crewmembers alive. |

Had people been predicting a Russian calamity, you'd have a point. Instead, as usual so far, you confuse drug addled hallucinations for reality. D. -- Touch-twice life. Eat. Drink. Laugh. |

Lurching along from one make do patch to the next its only a matter of time till one doesnt make do. this is akin to accepting o ring seal erosion or foam loss as normal/ hey we must keep the station going, so the electron has disconnected monitoring, and many other systems are having troubles, and requiring continious servicing. Sure our environmental sensors are off line, and are suits are a patchwork quilt of troubles. It will be fine..... said before columbia It will be fine Said before the ISS disaster..... The safety investigation will find very similiar troubles... Congress should appoint a safety board to inspect the ISS operation before disaster strikes.. HAVE A GREAT DAY! |

It may not just be a matter of replacing some parts to get them operational. While this is true, there are still ground units that the Russians operate on the ground (for training, testing, and the like) in addition to the ones on ISS. I'm sure that there are plenty of engineers that understand these units to some degree. It certainly makes things harder, but not impossible. Look at the number of "classic cars" that are still on the road despite the fact that their manufacturers are long gone... Jeff -- Remove icky phrase from email address to get a valid address. |
