    No way.... That is awesome!
    If u want to go on an expedition get a Land Rover, if u want to come home from an expedition get a Landcruiser!

    I think we saw it earlier. It was bright and moving fairly fast. We looked a way for a bit as it was heading towards the moon and then it disappeared. I'm guessing the sun stopped reflecting on it.

    Who sabotaged the space station?

    A few days ago NASA notice a drop in air pressure on the ISS.
    This is typical of a leak. The Astronautswere sleeping at the time and because the leak was slow, they were left to sleep and when they were awake, they were given the task to find the
    source of the leak a couple of hours later.

    They eventually isolated the source of the leak to a hole in the Soyuz space craft service module.
    The German astronaut stopped it by putting his finger on it and they repaired it with some tape.

    The thought was that the source might be a micro meteor, but inspection of the hole shows it's clearly drilled and from the inside of the Soyuz service module.
    (I thought it would be a bit funny if it was drilled from the outside.)

    So it's most likely it was done while the spacecraft was on the ground, but after flight approval testing of the assembled Soyuz spacecraft.
    the hole and leak would have been noticed in testing, so it has happened after that when the vehicle was moved and assembled onto the rocket.

    Some weird shit going on there.

    Accident by worker and covered up with a patch that fell off.


    It is claimed the worker has been identified.
    I would expect that he will spend the rest of his life in a Siberian salt mine covering up nuclear waste with his skills but this time without access to a drill.


    Yes and excellent picture Learjet

    It does make you wonder just how thick the shell of these space craft is that a small hole like that could vent into space. Most small drill bits that I know of are only about 20-25mm long. A hole that deep would have required a concerted effort to create. By the looks of the picture I could understand a hole 2 or 3 mm deep being made to mount something, but, anyone worth their salt would be thinking, "I shouldn't need to drill this long to mount a (whatever)". It seems like sabotage to me. Why? Who knows? Maybe ISIS will lay claim to it...... Or not given that it didn't work.

    What is interesting is what you (the average person) thinks a space craft is made of.
    They look all tough and built like a brick shithouse when they're sitting on a rocket. But they're quite fragile like aircraft.

    The big factor is that they need to be light, so the skin is usually not much thicker than an aluminium can. An inside and outside shell with insulating material and a bit of reinforcing like kevlar. The Russians typically rain atmospheric pressure with air which made their spacecraft heavier. The Americans typically used a lower pressure oxygen rich atmosphere. This put less stress on the spacecraft and made it lighter, but as can be seen from Apollo 1, it has some disavantages. Apollo 1 used 100% oxygen (EAN100) rather than something like EAN50 which was used after apollo 1.

    So really it's quite easy to put a hole in a spacecraft. The moon landers literally just had a single thin sheet of aluminium. Buzz Aldrin commented that you could poke a hole in them with a pen if you weren't careful.

    I was quite surprised by how big the hole is and was amused at how the patch survived this long before the leak became obvious.

    Based on the size of the finger (assuming the owner doesn't have huge sausage fingers) that hole is between 2-3mm diameter and the thickness, of what is most likely quite soft aluminium based on those scatch marks, a little over 1 mm.
    It is merely a matter of seconds to create that hole with a good sharp drill.

    The worker may have actually wanted to pre-drill for the larger hole above and then realised it was on the wrong side, but the idiot should have also used a punch first.
    The cover up patch should have held the whole time it was in space because of the inside pressure but maybe this pressure caused it eventually to puncture and then of course no pressure could hold anymore if the adhesive failed

    I am sure somebody who REALLY wanted to sabotage this mission would have known that such a small hole would not have caused more than an inconvenience.

    Interesting about the construction, it's not something I'd ever considered, though, it does make sense. Every ounce, especially to reach escape velocity would use a LOT of fuel. I'd have considered that at that velocity through the atmosphere the shell would need to be strong to prevent distortion. Your premise of a errant drill hole by a worker may be true. For sabotage, I wouldn't put it past a person thinking that a small hole like that would cause catastrophic failure. Look at the urban myths that persist regarding bullets and aircraft.

    It depends where the hole is and how to get to it as far as the danger is concerned.

    As nomeat said, he'll have no trouble finding salt for his boiled cabbage I suspect.
    The fact that there's a highway to hell and a stairway to heaven says a lot about the anticipated traffic flow.

    The small problem is, the only opportunity the Americans had was when the Soyuz was in space.
    After all, if the hole was done on the ground then they would have found it during flight testing. If it was done during the transfer phase, then the service module would have depressurised on the way.

    Where the hole is, it's almost impossible to drill that hole in space. In order to drill the hole, you need friction, an anchor point or a pressure/jam point. In space, none of those are available from where this hole is located.
    The most logical conclusion is of course that it is a mistake that was covered up.


    When it comes to holes. The pressure difference between the inside of the Soyuz and the outside is only about 14lbs per square inch.
    This is about the same pressure that my feet put on the ground.
