Radiation protection

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.

Gold news

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.

Dairy, Eggs and Space Settlers

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
