| Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web. While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself!

One way mission? That would be a bit barbaric. |

My thoughts exactly. Some, like Aldrin propose to have astronauts spending decades on Mars with the eventual possibility of "retiring" back to Earth... it's a bit better than leaving your astronauts to die, but it still has problems. Like how people would be able to live on Mars for decades, and how to prevent your people being stuck on Mars when budget cuts axe the retirement landers...
Uh... no. I don't see why you need to send thousands of people to the Moon to send a few people to Mars. And the Moon is really crappy as a destination for colonisation... it has a lack of resources and mean temperature cycles, as well as gravity that might not be high enough for prolonged human habitation, which is why it might actually be better to build orbital colonies from lunar materials than colonise the Moon itself. |

In for a penny, in for a pound. If you spend all that time, money and effort getting a man to mars, I see no reason why you can't bring him back. Moon colonisation to help getting to Mars never made much sense to me, like building a forward supply base to help Antarctic expeditions, in the Channel islands/Tasmania/Puerto Rico. |

Yeah... pretty much. IMO that can extrapolate to the mission designs as well.
Yeah... pretty much. NASA has been going on about a lunar base for learning how to survive on Mars for some time, but IMO it's a load of rubbish- the Moon is no more of an analogue to Mars than the Atacama desert or McMurdo valley, which could potentially be used to test mission equipment or variations of it (NASA in fact already does this with their surface probes) at a fraction of the cost, and other mission hardware and techniques can be tested on Mars probe missions to the intended environment, or even missions to NEOs. And other technologies could even be tested on satellite-like technology demonstrators, almost like Deep Space 1. The only real reason to go to the Moon is partial gravity research. We know very little in that regard. |

Although the carcinogenic effects of radiation could render the astronauts badly damaged, i concede that radiation does not have to be a short-term hazard in space. Only because we're not getting back what we've put in. In a British reactor ( Who's at the technological forefront now?), 16 KW has been achieved [i think]. |

Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea. "It is the old wound my king. It has never healed." | |
