    Question Venus surface Lifeforms strategies/physiology

    Did not want to put this question in the main spaceflight forums, since it is entirely speculative, and hopefully avoid certain killjoys on this bbs. It appears that Venus was more like Earth like at start. Let make some assumptions. If complex life up to simple animals (pre-Cambrian...

    Solving the debris hazzard at high C speed.

    Yes, I know we are not likely to travelling this fast in this Century or the next, because of the energy considerations etc. Still, I think some other barrier besides the difficulty achieving high speeds is out there, and my estimate is that .45 C is going to be near the limit. Why? As...

    Free Floating Black Holes

    NASA Shuttle Program could have Expanded Lunar Exploration

    I read the report by NASA regarding what pitiful payload a single shuttle could deliver for lunar exploration. A 500$ Mil dollar flight to send a small probe to land on the moon. I think it is generaly acknowledged here and other space sci sites, that when NASA was tasked with studing a...

    The Implications of Kepler Mission for Twin Earths

    Out of 2740, candidate stars, only 1 planet we can call an earth-like has been found. Kepler 62f, 1.4 size of earth. This planet IMO is semi-twin, and I will make an adjustment at the end for that. Now Kepler was able to detect the candidate 2740 stars with planets because they had planets...

    Heat Conservation on any Titan habitats

    What type of design would be best for a base on Titan, with the goal of reducing heat loss to a minimum. From the information i've read on-line it appears that the following facts get in the way using Antarctic solutions to controll temperature. 1) Titan's surface atmospheric pressure is...

    Fastest Possible Interstellar Ship Construction and Launch

    So how about that When Worlds Collide Scenario, but with a twist. A low mass black hole is inbound at tremendous speed. (it was part of a double star and the other star went NOVA and sent companion black hole loose.) There is window of 10 years before the black hole arrives and it's course...

    Discussion Kepler Mission, Finding Lots of Uncolonizable Planets

    The Kepler mission puts on a optimistic face, on some really disapointing data. By Now we should have confirmed Earth Sized Worlds in K type Suns, within the Habitable Zone. (it's too early for G stars like the Sun.) Kepler keeps finding compact Solar Systems. This was Never Expected. A gas...
