A great deal of fuss was made about the first “official” Briton in space. He went to the Russian built space station in a Russian built rocket with another Russian and an American, and joined the roll of hundreds of people who have visited space. This international co-operation works in space, but not on planet earth where the same nations are making accusations of perfidy against each other.
I suppose that for now space is not worth fighting for; some think the game is hardly worth a candle with huge costs and very few returns in the short term. In the long term, over the next three or four thousand years space travel and colonisation of other planets and moons is probably essential to the survival of the human race as we now know it and to the survival of many of the species of life on this planet.
With our planet’s population at nearly seven and a half billions and rising we will need outer space in the future to make up for the crowded inner space that will inevitably restrict and possibly end human life.
