A human Mars mission?

Colby Pottinger made the phosphor on my monitor glow in such a way as to indicate that: A important thing to remember is he is in Europe, but is demanding that the USA spend to money for the mission. Since it is not his taxes he in affect is asking for a free ride. Not surprising, since we've been providing Europeans with a free ride for several decades now... -- simberg.interglobal.org * 310 372-7963 (CA) 307 739-1296 (Jackson Hole) interglobal space lines * 307 733-1715 (Fax) http://www.interglobal.org "Extraordinary launch vehicles require extraordinary markets..."

Your DoD has been given that amount extra to raise your flag all over the middle east. That has to do with *protecting* our people, and yes our interests, from *attack.* On this side of the big pond the view is its to do with securing oil supplies so American motorists can continue to have cheap gasoline, to ensure cowboy george wins a second term. The cheap gasoline issue, I'll grant you, was at least a moderate influence, although I doubt it was ever more than a peripheral bonus. But the re-election issue is not supported by the facts. Bush 41 went to war against the same adversary and it had no effect on his re-election. He still lost. Ergo, Bush 43 has no particular reason to believe this war will improve his chances of re-election. By the way, *your* people are in Iraq, too. Lots of other countries told the US "no" when asked to help, the UK did not. So either the UK is a bunch of spineless bureaucrats who no longer can do anything at all without the approval of the US, or they (gasp!) agree with the United States. I doubt you like either option. Mars is closer to the mineral and metal rich asteroid belt, and who's to say there is no money to be made on Mars, if Mars has water, it'll open up a whole new set of opportunities for the human race. Mars is at the bottom of a deep gravity well. The asteroids are not. The potential water is dirty and frozen in the soil, where it will take great effort (heavy, electrically expensive equipment) to get to. That equipment will have to be landed on Mars. It could easily be cheaper in mass, propulsion, and electrical requirements to just carry your own water to an asteroid. Brian |

Aurora does not involve manned spaceflight, it is only a precursor to such a mission, some ill-defined day in the future. So are the NASA Mars probes. Brian |

On the other hand, the English were *not* the first to the New World. They were third or fourth. It doesn't matter who gets there first, it matters who gets there with the biggest long-term committment. So I fail to see why it is important that the United States be first to Mars. The British did not wait until things were pefect back home, but they did wait until there was sufficient proof that colonizing the New World was economically promising. And even then, there first colony failed and the second one survived only by near-miraculous last-second reinforcements and resupply arriving from England. Brian |

The longest Apollo mission lasted 12 and a half DAYS. The moon is only, 250,000 miles away, even a direct shot to mars is a minimum 45 million miles, and a Hohman type orbit is 300 million miles. It ain't so easy folks. Actually, it only took a Saturn-1B launch vehicle to put an Apollo CSM into earth orbit (done many times for Apollo, Skylab, and ASTP). Saturn V was primarily used for lunar missions, being capable of putting a fully fueled LEM and Apollo CSM (nearly) into lunar orbit (the CSM's main engine was used for lunar orbit insertion). And, of course, a two stage Saturn V was used to launch Skylab. Meant to say "moon orbit", but I'm close enough. I realize the Apollo missions carried the lander as well, but the point was "3 men, 12.5 days", because you'd need a lander for Mars too. Skylab just sat in low earth orbit, didn't need the extra weight of a rocket engine, or the fuel to push it. I'd forgotten how big Skylab was though: http://www.hq.nasa.gov/office/pao/Hi...ms/skylab.html Patrick |
