Large SRB test site in Florida
In article ,
says... "Rick Jones" wrote in message ... I'm going to to ahead and pick the nit on the fifth one there and say you are counting an as-yet un-hatched chicken there. Four! Four options for the resupplying mission! It is perhaps even more of a nit, but option 2 ceases after the fifth launch (per http://en.wikipedia.org/wiki/Automated_Transfer_Vehicle) Three! Three options for the resupplying mission! http://en.wikipedia.org/wiki/H-II_Transfer_Vehicle isn't terribly specific about continuing launches but I'll refrain from going down to two What is this, the Spanish Inquisition? No one expects the Spanish Inquisition!

LEO is getting crowded. now abandoning ISS might save a crew, although a debris impact could damage a attached soyuz. so crew survival, isnt assured. But if it damages the Soyuz, ISS would be used as a safe haven until replacements could be launched. beyond which a damaged ISS without a crew can endager anyone under the ground track.. Bull****. *ISS isn't going to quickly fall out of the sky if it is unmanned. *Orbital mechanics, get some... so having a few emergency transit vehicles in silos, with cargo pods ready to go is just smart thinking like planning for a shuttle stuck at station. if we can pay to keep ICBMs ready for instant launch then we should be able to afford some emergency supplies to orbit launchers Bull****. *Different programs, different priorities, different levels of funding. now imagine the horror, a small piece of space debris too small to track damage ISS and just one of the 2 soyuz lifeboats. Damaging both at the same time is a neat trick. *How is that supposed to happen? *Certainly it's possible, but it's highly unlikely. *Space is always going to be a bit risky. *Grow a pair and accept the risks. 3 crew members get back safely the remaing 3 die waiting for some crucial supplies, the stations control is lost and ISS breaks up depositing debris that survive re entry all along the ground track hitting some major citys nasa is put out of business after some congressional hearings. all preventable with just a few emergency cargo rockets had been built The sky is falling! *The sky is falling! We've all heard this bull**** before, and that's all it is. 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 NASA failed to plan for a shuttle stuck at station, and I was laughed at here with the sky is falling till columbia, then posters quit laughing and nasa made plans. it is commonly accepted that a debris strile to anything in space will lead to more debris. has anyone given thought to ISS where a primary debris strike will likely do colateral damage to attached modules, soyuz etc? and i dont believe soyuz are protected by blankets like ISS modules are. with the increasing amount of orbital debris, many are too small to be trackable one day we may get a mayday call from ISS and the ability to launch something to help instantly may not only be the difference between life a death for the crew, but for many on earth too.... now go ahead and laugh, chicken little etc. but i will be here to remind you if a dister like this occurs |

I bet you enjoy pulling the wings off flies, don't you?
Give a cite for your contention that it is commonly accepted that a debris strike will create more debris. I'd contend it is just as likely a bolt striking an orbiting object will punch a whole in it. You have visions of sciFi space battles in your head apparently. |

This part is true. *Debris is an issue and big collisions obviously produce more, smaller, pieces of debris. *But the details are pretty complicated and are the subject of many, many research papers. Jeff -- Well given the dramatic increase of in orbit debris planning for a mayday call from the station is probably a good idea.... or wait till the accident occurs and kills some crew, which they are well aware of the risks. but for eartthers seeing the ISS ground track littered with modules from a out of control station costing how many billions? which could of been preventable with a small contingent of stand by vehicles... congress will zero nasas budget if such a disaster occurs....... |
