I wouldnt be surprised if the US got back into the game in a big way in the next 10 years or so. Once the Chinese really get going. They are planning a manned mission to the moon. Once they do that who knows, maybe there'll be a second space race.
Competition is good. In 2019, it wil be the 50th anniversary of the Moon landing. If China is there with some astronauts and a Moon base, perhaps that will wake people up. Putting a man on the Moon seems to me seems like superpower status. A Moon base with regular visits, even more so. China is up and coming, the tired USA is not.
Space exploration doesn't make money, spinoffs or not, but it is the classic investment of huge payoffs down the road. Nowadays there are more and more ads on TV showing Earth in space, like we are already off it and a space faring civilisation. We are in a small way with the International Space Station, but the ISS is a dead end. We need to colonise the Moon because the tech already exists.
