It’s been more than fifty years since the first man stepped out from the earth but the development of space exploration technologies are a little too slow while most of the other technologies have developed exponentially. Main reason for this is the return of any investment in the development of space exploration technologies, only comes a long time into the future (after one generation) and the risk of these investments are very high. So when there is no exponential investment, how can a technology be developed exponentially? That’s history! How would be the future of space travel? Would it be same like the last five decades?
