There are nowadays dozens, so not, hundreds of companies offering or planning to offer tourist trips to outer space. Most of this proposals only provide a flight up to a hundred kilometres above the surface of the Earth, technically this is outer space. But those trip only offers a few minutes outside our atmosphere, so we don’t consider this as “real” space travel.
Of course we believe that anyone should have the right to start his/her own space travel agency, we of course want to do same in a few years time, but we seriously doubt whether these current initiatives are helpful for the start-up of human settlement of Outer Space. First most space tourist companies are not interested in permanent settlement of space, since they didn’t have the budget to support such colonization programs.
But our second and most important argument is, that many space tourists companies, ask much money from their would-be costumers. There is a large range in prices, but they are usually in the order hundred thousands to millions of dollars a flight a person, this means that only a few people in the world can actually afford this. Further of the worlds millionaires only a small percentage is likely willing to pay a large sum of money for a few minutes in Outer space. So we expect that these initiatives wouldn’t succeed due to lack of sufficient demand.
Our conclusion is therefore that the current Space Tourist proposals are a dead-end to humanization of Space.

Even since the time of Gerard K. O’Neill space colonist advocates are concerned on the issue of producing of meat in future space colonies. One of the main concerns is the conversion rate of meat. This means the amount of food which is needed to feed livestock to produce an amount of meat, e.g. the conversion rate for cattle is 10:1, which means 10 kg of food is needed to produce 1 kg of beef.
Anyone would know that agricultural space is a precious commodity in space settlements, especially in the early years. So it’s unlikely that in the first years of space colonization there will be a native meat industry. But the cost of importation of meat, even without any kind of tariffs, will be prohibitive high. And due to our preferred location in the Sun-Earth’s L4/L5 points, it will take months before a cargo meat will arrive from Earth to our colonies.
A possible solution for this problem are the use of plant protein based meat analogues. In recent years meat analogues are rather good in mimicking real meat products, so good that is sometimes hard to distinguish from real meat. Another solution is in vitro meat, in this process animal tissue is cultured in the lab. The main advantage of this is that it is a lot easier to transported (deep frozen) samples of tissue of several kinds of animals to distant space colonies than entire herds of animals.
Another advantage of in vitro meat is that it offers the possibility of a broad range of kinds of meat to choose from. Furthermore the technology used can also be applied for medical purposes. Therefore we can conclude that in vitro meat is a valuable technology to be developed by Space colonists.

Here on Earth, many people are fearing the risk of contamination of genetic engineered crops. But in space there is no risk of contamination of terrestrial crops, by their genetically engineered counter parts. And this provides space colonies an economic advantage.
While it is likely that here on Earth governments will put (irrational) restrictions on genetic engineering, Spacer governments can introduce more liberal legislation on trans gene crops. This mean that space colonies can engage in molecular farming, and that they can export the compounds of therapeutic value to Earth.
This scheme is lucrative if terrestrial governments continue to block or restrict the growing of pharmaceutical crops. Since pharmaceutical molecules have a rather high value per unit mass, exporting those can be very profitable, while back on Earth people will oppose their production there.
Time will tell us if molecular farming will be a viable source of revenue for space colonies, but the possibility is there.

In this article, I’ll restrict myself to space colonies in Near Earth space.
Since space colonization cost a huge amount of money, it is necessary that the first space colonies are making profits. For the purpose of this article I’ll assume that space colonies will be financed primarily be issuing corporate bonds at international stock markets. Continue reading On the economy of Space Colonies

In another post I have presented arguments against returning to the Moon. Although more and more people are discovering that the prospect of mining Near Earth Asteroids is superior to Lunar mining activities, there are still people, like Newt Gingrich, who believe that humans should establish a base on the Moon. As Eric Drexler argues, returning to the moon is a waste of money. Continue reading Is Helium 3 really the future?
