Monitoring ISS Air-to-Ground
Volunteers are always needed to keep an ear on the voice comm between ISS and Earth, while you're on line doing something else -- and then can flash a message to sci.space.station (and if you're willing, an email to me directly, to joberg at houston dot rr dot com) about anything newsworthy or curious. I can follow up, make some calls, and work through my NBC clients. You can get onto the streaming audio via http://www.chron.com/content/chronicle/space/index.html and find/select the option to listen to the space station audio channel. There are a limited number of ports, so don't just leave it on and ignore it, please. But if you can help all of us keep getting real-time insight into what's going on in space, the value to everyone will be enhanced. Thanks! Jim O |

Volunteers are always needed to keep an ear on the voice comm between ISS and Earth, So far this morning, the only "strange noises on ISS" I have heard is static. No DPC yet. Also, much of the juicy information is sent to the crews via the various "forms" such as form 24 and the daily tasks lists, at least on the USA side. The russian conversations seem a bit more candid, but for them, there is no sense of panic if they hear a noise. I think that the USA is acting somewhat like a backseat driver. They see/hear stuff, but they can't do anything because the russians are at the wheel, and the russians aren't panicking, while the USA is affraid it might be serious/catastrophic/dangerous (like any good backseat driver would). What should be asked of the russians is whether such sounds had been heard on MIR as well. |

So I only heard "Houston , Alpha, for the DPC" spoken by Foale. (The DPC is usually all ground to ISS audio). Many many many minutes later "Houston Alpha, Space to Ground 1". And no response. They must have privatized the ground audio and forgotten to deprivatize it. |

By 04:40 EDT, ground finally came on, explaining to crew that they had had
comms problems on the ground. So even the Alpha crew had not received any message from houston. |

Treating unexpected events as things to be understood is a good safety practice. In fact, this issue is addressed in the CAIB report. It is also addressed in the Diaz Report, number F41: Anomalies are problems unless proven otherwise. Nothing very profound, it restates good engineering safety practices. It's also good engineering and operational practice to quantify if the anomaly is a problem, a Problem, or a PROBLEM. Not all failures and anomalies are created equal. Running full tilt in circles looking for something when you don't know what it is wastes time and energy that could be better spent elsewhere. If you don't have an ongoing indication of a problem, you can't fix it, and you probably can't even find it. D. -- Touch-twice life. Eat. Drink. Laugh. |

If you don't have an ongoing indication of a problem, you can't fix it, and you probably can't even find it. I had this problem with one of my old cars. It would occasionally die, but then come back to life several minutes later. While this was a Problem (as opposed to a problem or a PROBLEM), you simply couldn't debug the issue until you could reproduce it on demand. That's the part that hal keeps missing. If you can't reproduce the problem, and there are no traces of the problem in your telemetry, there is simply nothing you can do. The first step on the path of operational wisdom is realizing this. If you are going to do long duration missions, you simply must plan on redundancy and on sometimes living with problems (as opposed to Problems or PROBLEMS) for months on end. If your ship isn't robust enough to do this, you have no business venturing beyond LEO. Eventually, I found that rapping on the computer case with my fist would cause the running car to stumble and die. A $40 junk yard computer fixed the problem. We had a few little 'p' problems on the boat exactly like that, so did every boat in the Fleet. It's the nature of ongoing operations. I'm guessing that ISS astronauts feel the same way about the Elektron oxygen generator that I felt about my 88 Olds Calais. ;-) I felt that way about some of the equipment I worked on. I learned to never frown at it lest it's mood detector function. D. -- Touch-twice life. Eat. Drink. Laugh. |

The first step on the path of operational wisdom is realizing thi Ahh but it might be the beginning of a real killer PROBLEM! Better to investigate unknown problems so you have some idea of whats up. bang rush out to look today NO! But if it occurs again dont wait till july to take a look Hey this is my opinion |

And I would add that precautions should be made for dealing with a problem if it should perhaps have the capability to turn into a Problem. This can be ensuring that backups are in place and operational, contingency procedures reviewed, etc. Take the hint and do the homework. Certainly. But the homework has to start at the design phase, not once the craft is flying. Panicking -- which I don't see evidence of here -- could easily just make things worse. I don't see x-nauts diving into the Soyuz and flying around burning the fuel, close to the station; I don't see x-nauts diving into EVA suits and crawling all over the outside unprepared with the inherent risk of EVAs; I don't see the ISS being abandoned. Etc. You see folks (bob) advocating exactly that. It's them I'm trying to reach, not you or Herb. (Who mostly know these things.) When you have a problem, with a little 'p', sometimes it takes a bit of patience, persistence, and some steel ones. Been there, done that, washed the Tshirt so many times it's more holes than shirt.
