    I was surprised by the news. Their launch vehicles (nowadays) have seemed very reliable. I'd bet they will find out what happened pretty quickly and be able to resume launches.

    If they start running low on loo rolls up there, there's always the flight manuals! :coffee:

    I hope they do regain communication with it. Hate to see this kind of problem, but it happens.

    Things can still change - ever the optimist, me! :)

    Yes, I guess it could fall on someone's head earlier - :devil: ever the pessimist, me! :devil:

    Just out of interest, is there any form of escape pod on the space station?

    I believe they do. Not sure if they are return to earth or just hang around in space waiting for rescue type though.

    reentry due in the next few weeks.

    "Any components that are not vaporised during re-entry are likely to fall into the ocean or land in sparsely populated areas."

    Though as the reentry window is about 2 weeks and they have no idea where or when it will land, I'm guessing that probability is just based on the fact that 80%+ of the surface matches their claim rather than any scientific data.

    It's a great shame they haven't been able to correct the fault. Hopefully there will be things to learn that will improve the chances of subsequent missions being successful.

    As for the dangers of posed by space hardware in general surviving reentry... probability being the fickle thing it is (and assuming the odds of being hit by a chunk of space vehicle are better that those of winning the lottery) sooner or later a bit of some decaying satellite or other is going to land uninvited in my back garden. Just hope it misses the bird table!:wink: :coffee:

    How big would we expect the "bits" to be?

    The largest bits I believe are the re-entry cone (designed to survive re-entry obviously) and I believe a few other bits. Then again it's size + speed = danger! A little bit hitting you at high vorticity is not going to do you much good.

    When I started reading the article I imagined the amatuer astronomer to have a regular sized telescope and be recording from his garden shed or suchlike - then I scrolled down and saw the picture of his kit ... WOW!!!

    I was also surprised at how often it is circling the earth - but assume it would be too small in the night sky to be discernible with the naked eye?
