its a safety issue with the current tools ie, the space shuttle. Current proposals are leading towards a apollo-style booster with a capsule, which has a nearly flawless service record. With the right tools you can get the job done.
No orbit short of geosynchronous orbit at 22,000km is anything close to stable. Even at 600km there are a lot of molecules which disrupt the orbit of the space station. Deorbiting is really your only option at the end of service life, or re-boost it every couple of years. Deorbiting is obviously the most cost effective (and ultimately, safest) course of action
again, it wasnt canceled because of bush, it was canceled because such a mission cannot be held under the new flight rules imposed on NASA by a congressional comitee which contains both republicans and democrats. One of these flight rules is that the shuttle can only fly to ISS so if tiles break they have a lifeboat in the station and a possiblility of repair. Hubble is a vastly different orbit and cannot be reached on a ISS mission, nor would the shuttle be allowed to.
so you can all shut up about this being a democrat vs bush thing. When i saw the headline this morning on/. i thought to myself gee, slashdot is behind on things, cause most of us in the space industry have known since the middle of last year that hubble was never again to be serviced... sorry you guys have to hear it now. Do a little research before you make an ass out of yourself... politics, bah!

Due to new flight rules imposed on NASA, the space shuttle can only fly to the orbital height and inclination of the International Space Station, so that if something goes wrong with the tiles they at least have a "safehaven"... seeing as the orbital height of Hubble is lower, and the inclination not as severe, a Hubble mission will be impossible. thank the people who wrote the flight rules.
Heard an interesting lecture on methods of repairing tiles on the shuttle from two gentlemen whose job is to report back to nasa on feasible repair methods for shuttle tile. Regardless of their outcome (ie, they find a quick and dirty method or not) the space shuttle will still have to obey the previously listed flight rules.
Goodbye, Hubble.
Due to the space shuttle incident nearly a year ago and some BS government meddling, one of the new flight rules is thatt the shuttle can **only** go to ISS orbits, so that they can dock if more tiles break. This means there is no possible way to service Hubble, which is on a different inclination and orbital height.
Hubble is doomed to die, and no it wont be brough back to earth and put in a museum.

Thats not the Saturn V either, im pretty sure what you are referring to is the Saturn IIB which is on display at a rest area on I-65 when you enter Alabama. If you were traveling from **Anywhere** to louisiana you wouldnt drive past huntsville (its about 17 miles off the interstate)

doh, that isnt the huntsville one, thats the one from Johnson Space Flight Center. Here in Huntsville, its the Marshall Space Flight Center, and the rocket itself is on the arsenal (at space camp)
The Saturn V that is standing up is a mockup, the real Saturn V is lying horizontally on its land transport carriages (essentially individual, blue, trailers)
Interesting anecdote, back in the 70's someone wanted to take the Saturn V away, to the smithsonian or something. Werner von Braun, outraged, went out one night and smashed in the axles on the transport carriages to prevent their movement. They decided not to take it away.
For being in such bad shape it still looks beautiful. I saw it about a month ago (I go to school in huntsville) Very impressive to be a mere 10 feet from the vehilcle. I remember in high school when I visited on a trip they let us sit in one of the rocket nozzles to get our pictures taken (which probably didnt help the damage any) but even as a kid youre awe inspired sitting in a vehicle that could take man to the moon

the University of Alabama - Huntsville started using it this year. I'm thankful that I have completed all my lib art requirements and that turnitin.com doesnt work on mechanical/aerospace engineering homework:)

Its a simple number to describe the results of a complex system.
50% = % enhancement in group - % enhancement of control group.
The brain is amazing, but looking at raw output it is not difficult to come up with a percentage to represent typical results. YMMV.
They dont even need IR cameras. Infrared wavelength light is detected by normal cameras. What do you see? A bright halo of white light. So a camera pointed at an intersection would be able to pick out the car with great ease, in essence, it'll be circled for you

When trying out Rubies of Eventide someone mentioned to me a thought I hadnt considered before, that not all MMORPG's *want* to be full. For example, Everquest has half a million subscribers. Thats at least 5 mil a month in the bank for them, which is a chunk of change. And for me at least there are enough idiots on any server I've ever played on for me.
Perhaps losing the people who lose interest is a GOOD thing.
... but you must remember, if the ship needs to be restarted on ascent, the catalyst pack will be ***very*** hot to the point of spontaneous combustion of the reactants, regardless of the other factors.
Not really. You would still have to pump the fuel and oxidizer through the engine, and in order for the turbopumps to pump the engine would have to be running (both systems are interconnected). So in short, no purge for you!
Depending on the design of their hybrid, position of the nitrous tank will be key, as the nitrous oxide tank will deplete, mass-wise, quicker than the HTBP (rubber), resulting in a CG shift to the rear of the spacecraft.

Yup. Saturn V can be retrofitted for a Mars mission. Read Robert Zubrin's "the case for Mars"
