It only created a more efficient language using simplified words. That was scary enough for them to pull the plug. It just really depends what they use AI to control really. With NLP and Machine Learning in place the capabilities are quite scary.

No, it just descended into nonsense not it's own language. Marcus Chown debunked this on TV last month. Optimistic as ever

Solar radiation doses are more interesting due to the longer exposure. I think the theory is to put the water supply within the multi-layer skin. "Everything is air-droppable at least once."

If we decide, "nah, never going to happen" well, it's never going to happen. But, like Mark Watney, you solve one problem and then the next and then the next...until you get to where you want to go and get to come back again (if you want). And North Korea claimed (and maintains) that Kim Jong-Il's first and only round of golf was 38 shots under par, including 11 holes in one. Palace since 19 August 1972.

Edited by Hrolf The Ganger (28 Sep 2017 7.51pm) He has googled the wrong thing he has mixed up Cosmic and Solar with the effects of the Van Allen belts. Silly ex-teacher. Shielding or mitigating cosmic /solar radiation is a very significant issue that still needs a decent practical solution. Current idea include: * water shielding, recycled in a close system. * Liquid hydrogen shielding burnt as fuel * Hydrogen based polymer construction, I guess you burn you space ship as you go along. * Active deflection systems * or use of an asteroid as a ship hull, a metallic asteroid I assume.
