Cosmic radiation is one of the most serious dangers to human spaceflight and hence a serious issue for space colonization. Consequently radiation protection is no luxury for space settlers and without this space colonization is unlikely to succeed.
Researchers at the Australian National University have developed a new nano material that could reflect cosmic radiation. A thin film of the material could provide radiation protection of astronauts and space settlers. Compared to other shielding techniques this material appears to offer a light-weight protection.
Here a short video about the Island One space habitat:
Free space habitats like Island One are an alternative for, instance, the colonization of Mars. A major advantage of this kind of space settlements, is that they can be located anywhere, Continue reading Island One
As pointed out earlier the treatment of waste water is essential for the quality of live in space settlements. Waste water is full of substances which need to be removed from it, before it could be converted back to drinking water. In particular waste water is rich in nitrates and ammonium.

Due to unexpected circumstances I have decided to postpone the release of the new site, which was initially scheduled for August, 2017. If time permits the new site will be launched around October or otherwise at the start of next year.
Fraser Cain explains in plain language what Lagrange points and why these are of great interest for space colonization.

At The Space Review Eric R. Hedman is making a case for a manned mission to Mars in his essay The best reason to go to Mars. He presents two argument to implement a Mars program: Continue reading The case for Mars?
Scientists have discovered a new allow that is four times stronger than most types of steel. This alloy contains three parts titanium and one part gold. Yes, gold! This material might be used in artificial knee and hip joints.
If this titanium-gold alloy would become widely used in medicine, the demand for gold will increase and so will the price of gold. And this might be good news for space settlements as gold could be obtained from asteroids.
One caveat should be made. Central banks and the IMF still hold large gold reserves and they might decide to sell of their reserves to meet demand.
Many will have heard of terms like counter-terrorism and counter-intelligence. These are concepts used by intelligence agencies around the world. The former refers to identifying and arresting (potential) terrorists and the latter to identifying foreign spies. Continue reading Counter-lobbyism
Space colonization and livestock farming is a difficult combination, as livestock will require a significant amount of scarce food and space. Either of these will be limited in supply, in particular in the first space settlements. Hence (the first) space settlers will have to adopt a primarily vegan diet, as animal products will be quite expensive. Continue reading Dairy, Eggs and Space Settlers
In paragraph I-1 of his discourses Machiavelli discussed the different origins of cities. In paragraph I-2 he then turns to the different ways a city can be governed. Continue reading Machiavelli’s Discourses and Space Settlements – part 2
