It is funny how news arrives in pairs: ESA news of Venus Express's eventual implosion and now NASA announcing the establishment of Zeppelins flying over Venus... NASA Wants to Establish A Floating Cloud City To Study Venus Looking at the artist rendition and thinking of the intense heat on Venus, I can't help but think of how that would turn into a sort of Reynolds Wrap Grill Foil for people... -Pete |

As a long-range project, I wonder if constructing a venetian-blind (no pun intended, actually)-type of shield, around Venus' equatorial region might, over time, reduce its atmospheric temperature below a critical point, enabling a habitable planet. CO2 level would have to be dropped, in favor of a favorable oxygen level. Perhaps, seeding of the atmosphere, at the appropriate time, would do the trick. |

HAVOC? First thought April 1 publication date. NASA is acronym crazy, but HAVOC? But no, March 7, http://sacd.larc.nasa.gov/branches/space-mission-analysis-branch-smab/smab-projects/havoc/ Like the mission patch ... |

Since Venus has little or no way to deflect solar radiation including CME's and it is a good bit closer to the sun than earth how do they propose to shield the inhabitants?

Further reading reveals this to be more of a hope of EDI (entry, descent and inflation) and not EDL. They plan to inflate airships and create a floating city 30 miles up in the atmosphere, in a layer of the sky where temperatures are closer to earth's weather. They recognize the bone crushing high density atmosphere at the surface of Venus is not a place they would have a lot of success building a longterm civilization. Robotic exploration is planned initially... Eventually followed by the blimps. Bob, I agree with an early post of yours, I still don't see the appeal here when the moon is a few days trip from earth. Perhaps this is a case of George Mallory... "because it is there" wisdom... Is Venus Humanity's Next Home? Pete |

Lando Calrissian reporting for duty! :D but enough jokes...maybe they can also make some airborne algae...for implementing to Venus atmosphere...and terraform the planet? ;) non-profit org. Play4Life in Zagreb, Croatia, EU |

I think it would cost a lot of money and it's not really necessary. When the Sun becomes a red giant, Venus will burn up before we get toasted. In that point of view Mars would be better to colonize, gives us a few years longer to survive. I don't think this idea will ever become reality anyway. Venus is a far too hostile world to ever harbour people, even in its clouds. rOZZ Music Pictures |

Once I translated a book "The high frontier Human colonies in space" by Eugene O'Neill, who proposed to build colonies at the Lagrange points. I don't know if the idea is still discussed. Tullio |

Terraforming Venus would be done in a time-frame well within that of the sun's existence, as we know it. Of course, humanity's ultimate goal (IMHO) should be migration to the stars -- the Mayflowers of the future. Mankind is, naturally, adventuresome. Reason, for going there: Knowledge/experience in colonization. Granted, the latter would be gained in settling Mars. However, travel to Venus would be quicker/cheaper (for one-way trips, anyway). Mars presents its particular problems, namely, retention of a thicker atmosphere with a smaller-mass body. There would always be dangers present in living there, due to impacts of extra-Mars bodies. Again, I feel it should only be used as an experience-builder, on the way, off-solar. Two major areas that would need to be mastered: 1) Economically-feasible space-travel vehicles (not yet developed). They would have to be able to travel faster than the rocket-propulsion devices, of today. 2) Ability to quickly accommodate exposures of different micro-organisms (Earth/extra-terrestrial). |

Long before we can aim for the stars, we will have colonized essentially every rocky body of size orbiting the sun. Then we might have enough experience to dare to try and venture forth with some expectation of success a thousand generations hence when they finally arrive at another rock. |

'We' can't colonize anything anymore when all is dead, if all ever dies, that's the question. Cfr. The Big Crunch. Back to Venus though. rOZZ Music Pictures |

If the Pilgrims, et. al., had enough foresight, they would not have come to the "New World". We'd all be still on the Eurasian land mass, for better, or, for worse. Although most pbly. wouldn't opt. for a one-way trip to Mars, many would (and, have). We should go, because it's there. Besides, if someone should push the wrong button, and cause a nuclear war, there would be some of humanity who would survive. Some might not care about this argument, but it appears to be a good a one, as any. If I didn't value humanity, that much, I might not have had children. It's their future, anyway, not ours. Lastly, the Native Americans' ancestors, had an even more daring wander-lust -- they came over to the North/South American continents by foot/hand-made boats. That should be an even greater indication of humanities desire to discover/ settle new territories. |

Or just desperation to escape bad neighbours! ... Or overly competitive other locals?... For example, was not the euphemistically named Greenland colonised by a Viking outcast? Very good naming there to persuade others to join him to forge their green and promised land...

Lots of legitimate reasons. . . |

Greenland was green back then |

Greenland was green back then Greenland was a big ice covered rock when it was discovered, except for a few places along the coast. It was a masterful bit of salesmanship to call it Greenland back home. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required.
