Space news

We want to share two news stories on ScienceDaily relevant for space colonization.

Roadmap to enhance radioresistance for space colonization.

Cosmic radiation is by far the most serious threat for space settlement, both orbital and surface-based ones. Without adequate protection from cosmic radiation, human space colonization will be impossible. Therefore research to protect humans against this radiation is of crucial importance.

Widespread water on the Moon

Water is indispensable for human life and hence the presence of water is of critical importance for any Moon-based settlement. Contrary to previous scientific understanding, there appears more water on the Moon. However, this water is primarily contained as hydroxy into lunar stones.

Space settlements and cyber-war

The recent wannacry and patya attacks have increase attention to cyber-attacks. Both attacks appear to be politically motivated and hence raises question about the future of warfare. This is of particular interest for space settlements. There are two reasons why space settlements will be particularly vulnerable to cyber-warfare. Continue reading Space settlements and cyber-war

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.
