> If it is to advance human knowledge the results should be shared. It’s easy for us to imagine that this day and age there are no competing civilisations and that every country will wholeheartedly share their progress. I suspect China, as Russia and perhaps India at some point, sees itself as such a competing civilisation. We assume that those times have ended but i think they haven't. In this context China does it for its own benefit. I somehow doubt they are not already either actively probing, or considering probing, mars, the moon and asteroids. Japan does it - we know this thanks to, albeit anaemic, coverage in the western media. If China has even a little bit of respect for its thousands of years of history it knows that the next meaningful territorial and resource expansion is space and it is only natural that it will try to outcompete us. Secret or not from us it makes no difference for china. Colossus may have been secret but the science that lead to its development wasn't and thats more important than the product itself. Just as the uk had fertile ground for developing it and later on for developing many computing advances, China is now creating fertile ground for space tech. We should keep an eye on it, and promote news about their progress, so the average joe will understand that unless we invest even more in space development then we are on track to becoming a secondary civilisation, ridden by debt and petty goals.
