Anti-radiation medicine?

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.

Wast-to-value: an analysis

A recurrent theme on this site is the idea that the recycling of waste could be funded through the proceeds of the reclaimed materials and that consequently waste-disposal fees should be abolished. However, this raises the question if recycling is indeed a profitable venture? Continue reading Wast-to-value: an analysis

3D printing en masse

On ZDNET an interesting article about Markforged – a company that is working on a mass production 3D printer. As we have previously pointed out on this site, 3D printing is along side with in situ resource utilization one of the key technologies that will be of critical importance of making space settlements independent from terrestrial imports.

Spacers and robots #2

At there is an interesting article about a robot developed by Japanese scientists that could replace construction workers. As pointed out in the article the main motivation behind this HRP-5P is to deal with the country’s aging and declining population.

There are several reasons why this kind of robots are of great importance for space settlements. Building space habitats, mining of resources and so on, will require a lot of work. Through the use of robots more labor will be available and this will allow for much faster space development – especially if such robots can be assembled in space, which will further reduce launch costs.

Also, according to another article on, a long-term exposure to cosmic radiation could lead to digestive problems. Robots do not suffer from radiation the same way as humans do, hence they could start building free space habitats while science works to devise methods to protect humans against cosmic rays.

Sewers and Taxes

Sewers are the summit of human civilization and taxation is the price of civilization. So we are supposed to pay sewer tax, right? No, not really. In this post I will explain how space settlements could fund a sewage and waste water treatment system without having to collect sewer charges. Continue reading Sewers and Taxes

Encryption clause

Article II-10, paragraph 3 of our draft constitution:

A well protected privacy, being necessary to the security of a free Society, the right of the people to use strong encryption in correspondence shall not be infringed.

The purpose of this clause is to enshrine the right to use of strong encryption and to make laws mandating backdoors in encryption software unconstitutional.
