On ScienceDaily we found an interesting study:
Soviet-Russian cosmonaut Alexei Leonov has died at the honorable age of 85. He is known for being the first human to have made a space walk. As such he is an important figure in the history of space exploration and the eventual humanization of outer space. May the Universe have his soul. And we also want to express our condolences to his loved ones.
Matthew S. Williams has written a good and elaborate article about space habitats on Interesting Engineering:
Williams discusses the basics of orbital space settlement and the major benefits and the important problems associated with this concept.
A pair of O’Neill cylinders, one of the habitat types discussed by Williams (source: NASA).
As pointed out in a previous post centrifugation is the method proposed in space colonization literature to replace gravity in orbital space habitats. Though the centrifugal force is the most well-known effect of a rotating object (if not, consider your washing machine for a moment), its sister force, the Coriolis force is less known. Continue reading Coriolis effect
We have noticed that orbital space settlements are a rather unfamiliar concept for many people. In particular people find it hard to understand the meaning of land withing the context of a free space habitat. In this piece we will try to explain some of the essentials of orbital space settlements. Continue reading Space habitats and land
Once again we list some interesting science news items, we believe are relevant for future orbital space settlements. Continue reading Science round up 3
Water is essential to human life – as our bodies consist for about 60 percent of it – and finding a suitable and abundant source of water is crucial for the establishment and survival for orbital space settlements. Fortunately water is composed from two of the three most common elements in the Universe: hydrogen and oxygen. Continue reading Asteroids and Water
Cosmic radiation is one, if not the most, major obstacle to space colonization. Different proposals have been made to address this issue. However, scientists have discovered that a protein called URI can protect against high dose radiation.
Though this research is done in mice and with the intend to help cancer patients through radiotherapy, it is still highly relevant for human space settlers.
I have just updated our Space Settlements 101 page. Over the next months I will further update this page.
