WOW!! Scott Kelly grew two inches in space — but NASA is more interested in changes we can’t see When astronaut Scott Kelly arrived in Houston on Thursday morning, he was about two inches taller than when he left for the International Space Station a year before, according to NASA representatives. That’s pretty normal for an astronaut: Without the full strength of gravity pressing down on gel-filled discs between the vertebrae, they expand and lengthen the spine. It’s a weird but temporary side effect of spaceflight. https://www.washingtonpost.com/news/speaking-of-science/wp/2016/03/03/after-a-year-in-space-scott-kelly-finally-made-it-back-home-to-houston/ |

Especially not when the chipped window in question is the one that provides some of the best views of Earth. I don't know when this happened. Here is the story. A bit of debris chipped the International Space Station. That’s just one piece of a much bigger problem. When you sit around imagining life aboard the International Space Station (we all do that, right?) one thing you probably don’t want to think about is space junk slamming into your vessel. And you almost certainly don’t want to imagine a piece of that junk taking a chunk of your spacecraft’s window with it. https://www.washingtonpost.com/news/speaking-of-science/wp/2016/05/12/a-bit-of-debris-chipped-the-international-space-station-thats-just-one-piece-of-a-much-bigger-problem/ |

I have read that just one major collision in earth orbit could close down manned space flight in low earth orbit as it would make it impossible to prevent more serious damage. That is until we figure out a way to clean up the mess we have made over the last 60 years. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Can anybody lend me a couple of mill I need to spend a year or 2 on the space station , Hopefully that long will allow the discs in my spine to heal properly and return back to working ... You may think that would be to expensive a option to fix your back ... $10,000 for one disc replacement plus the cost of the operation and time for recovery . I have at least 4 that need to be replaced and they would need to be done 1 at a time over a 2 year period at least and then I would need to go through the whole thing again in 7-10 years . One day when you injure your back I can see that as a option . "Quick get him into the shuttle and take him to the zero gravity area of a orbiting space station " as a treatment so your body can repair it's self without any compression from gravity on the disc . I can hope that one day will come in my lifetime . |

The only problem is that the effects reverse themselves within weeks of returning to earth. I, om the other hand would be willing to spend the remainder of my days either in orbit or on the moon.

The only problem is that the effects reverse themselves within weeks of returning to earth I would like to think Bob that once they heal properly the normal compression from gravity would not be a problem . The problem on earth is once you prolapse a disc part of the inner part of the disc is pushed through the tear of the outa wall . So your disc can't repair the outa wall because of the protruding disc . So hopefully being in space will allow that part of the disc to return back inside the outa wall and then it may repair itself so on returning back to earth it would not prolapse just because of the disc compressing back to it normal position. At least I can hope it would work that way for both of us maybe we should set up a go fund me for the cash and maybe a petition to get nasa to allow us to go up there . what do you think I'm onto something there or should I just wake up from my dream :-) |

I would come too, I have several prolapses on my back and I have problems to walk, but not to go by bicycle. Viva il Giro! Tullio |

Another problem is that bone density decreases in zero gravity and I would guess that probably any relief gained by you or I or anyone else with back trouble would only last while in space. Once gravity has you back in its grasp the previous condition would return. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required.

ISS completed 100000 Earth orbits.This amount to the distance between Earth and Neptune. One orbit takes 90 minutes. Tullio |

Expedition 47 crew has landed in Kakakhstan.Tim Kopra (NASA), Tim Peake (ESA) and Yuri Malenchenko (ROSCOSMOS) are well. Tullio |
