Hubble Space Telescope Celebrating 25 Years of Unveiling the Universe

Uh, you didn't pay attention to what Bob's idea was, did you? Bob's idea was to boost a failed Hubble up to an orbit where we could never reach it again. freds reading comprehsion has never been good. my suggestion was service hubble by using space X, and then at end of life rather than deorbit, raise its orbit to a one thats safe. perhaps as little as 100 years. I believe ISS is a much greater risk, since it has many strucural parts that will survive re entry, requires station keeping fuel etc.. and has lots f drag since its so large. hubble is realtively small, in comparison with iss, Reboost is simple and easily achieved. As the parts age, the fundamental guts of the station are still sound. This is why I think ISS should be handed over to students as well and an industry consortium, and a plan to break it into parts, and rebuild those parts into Mission Modules. This mission module approach was developed by NASA in the 1960s and makes a lot of sense. It was actually in several Boeing papers before ISS was funded. Again, the nature of the bureaucratic minds in Washington see the presence of ISS as a hindrance to other things and they really haven't grokked succession plans for scientifically useful equipment. |

It's much more expensive to go up than to go down. And just what would be the point of stashing it somewhere where you REALLY can't get to it and how do you know it will stay there? Space X cost per pound for cargo is right around 10% of what boeing will charge. Some people here dont get the history of stuff like hubble Fred would you approve of tearing down indenpendence hall in philadephia? if they wanted to replace it with a office high rise or perhaps condos Hubble is a national treasure and should be put in a storage orbit. It should remain operational I agree. and if nothing else turned over to a consortium of universities for students to run That's both not feasible and a little nutty. No its not. You understand that as long as it's up there the United States Government is responsible for it, right? According to the Outer Space Treaty the US government is responsible for ALL objects in space, even those privately constructed and launched. This doesn't stop private use and is not a barrier to ownership by a consortium of universities. Such consortia run all manner of facilities, hospitals, nuclear power stations, you name it. They have the ability to operate this at no risk as well. and funded by a consortium of aerospace companies led by the majors. Why would they do that? Because they said they would if given the chance. snip -- "Ignorance is preferable to error, and he is less remote from the truth who believes nothing than he who believes what is wrong." -- Thomas Jefferson |

Anyone suggesting that the telescope is too far away and too old isn't familiar with the actual history of telescopes and how they increase in value over time. No one suggested any such thing. As usual, Bob is jumping the gun, advocating for putting Hubble into a "storage orbit" once it breaks down. That is not currently the case. Hubble is operating quite nicely and from what I read has a 95% plus chance of making it through another 5 years of operations. Jeff -- "the perennial claim that hypersonic airbreathing propulsion would magically make space launch cheaper is nonsense -- LOX is much cheaper than advanced airbreathing engines, and so are the tanks to put it in and the extra thrust to carry it." - Henry Spencer Agreed. However, the wrangling in Washington between JWST supporters and HST supporters, and the demise of the Keck Interferometer after a member of that team asked innocently, do we need space telescopes in a world of optical interferometers with adaptive optics! Had those that clip the ticket a little more contact with the university and industry communities they would have a succession plan that preserved both assets and made them both far more productive whilst enlarging their clippings. |

Oh, do they now? Cite said spare parts inventory. Who are you to tell me to do your work? lol. Precisely my point. Who are you to tell me to do your work? lol. You put forward a claim.

fred space command tracks over 20,000 pieces of debris.. they are evenly distribuited over earth. any one of which could fall and take out a airliner......
