I see multiple threads there Faldage; which one of them were you referring to?

Cool board, Faldage.
There are two threads I've gone through: one on interstellar travel and the other on the shuttle crew.
Thanks for the link.

If you've got plenty of time and the inclination, here's a page from the NASA site I posted earlier down below in Miscellany: http://spaceflight.nasa.gov/shuttle/investigation/sensors/index.htmlThis page has numerous thumbnail diagrams of the sensors going out in the order they went out. The thumbnails aren't of much use, but if you have patience and time, increase the size of the thumbnails and follow the time sequence.

Rubrick, where do you get the ten years? The unmanned missions to Mars have only taken around 18-21 months to get there, so a manned trip should involve no more than 5 years in space (2.5 there, 2.5 back). Mars ain't that far away, after all. Cassini will reach Saturn less than ten years after launch, so ten years to Mars must be taking the scenic route.
The ten years are the worst case scenario which must always be presumed before a firsts-time launch. If you have a small unmanned mission like the lunar rover then you don't have to worry about a leak in the oxygen supply before a launch. This light that candle and watch it fly!
Now there is only a small launch window for Mars because it and Earth are orbiting at different speeds. Miss that aunch window and you are likely playing catchup. If you don't launch then you will have to wait another 18 months for the next realignment. It could feasibly take 18-21 months to get there if all went well but this is nothing like any manned mission performed before so I'm guessing that they'll add a few months on to an each way trip to allow for hitches such as the realignment one above.
Structural damage due to speed is not an issue in space where the vacuum means there is no medium to incur fatigue. The only real risk of damage is landing on Mars and, with its lower gravity than Earth (but denser than the moon) the question of relaunch is going to be a tough one to answer.

That's where you go if you want to discuss politics or religion or other subjects that aren't really of concern to this board.
Hm. I had that initial reaction to milum's post, but then I thought he must be joking?
anyway, 'tis good to know about snurl, for them as wants to battle that notion out.
