Forty years ago today, two human beings set foot on the Moon. It was the first time anyone from our species had ever stood on soil not of this planet.
Without being able to provide any economic or scientific justification for it, I am firmly convinced that we need to go back to the Moon. We need to build a permanent base there and then even tourist facilities. We need to use the Moon as a launching point for Mars. Or perhaps I should say that after sufficient time has elapsed for these activities to be in the reach of non-astronaut/non-billionaires, I need to go to the Moon and to Mars.
