For a doable Mars mission you really need a dramatic cut in flight
time, ether a nuclear or ion propulsion for round trip. Otherwise the consumables, radiation exposure etc becomes a deal breaker. But FIRST we need low cost to orbit, and sadly low cost isnt possible in nasas culture ![]() |

All untrue. -- While its true we COULD do a mars mission with chemical propulsion, the risks costs and time involved just isnt practical. like bicycling across the US sure it could be done but commion sense indicates its not practical. besides with such a long flight time a mechanical breakdown could see the entire crew die a long slow death. a bad day apollo 13...... |

While its true we COULD do a mars mission with chemical propulsion, the risks costs and time involved just isnt practical. Bull****. A great rebuttal, there. I know, you've been over this many times before, and I could track down the posts .... besides with such a long flight time a mechanical breakdown could see the entire crew die a long slow death. So it was impossible for Europe to discover and explore the New World... How many of those wooden tubs had cameras on board? (And the loss rate of wooden tubs was pretty high even just sticking to ordinary fishing along the European coast -- so maybe people were used to the idea of losign 50 or 100 guys every voyage.) well at least the crew had air to breathe and could fish for food and werent getting a possible killer radiation risk on the way. beyond which we need low cost to orbit, once thats accomplished everything else gets easier. I'd say Bob came up with a good point on this one. /dps |

Of course you would. *But you're just a nymskull, afraid to associate your name with what you'd say, so what you would say carries very little weight. I'm pretty sure it's trivially easy for my name to be associated with what I say, but then I knew replying to you was just a way to become more irritated by your attitude. Sorry, carry on being a *******. /dps |
