Well, let's hope they succeed!
Hope people can put politics aside and appreciate another step forward for humanity and science.
Good luck to all involved!
In fact I think it's how we should solve all our international disputes: First country to put a man on mars gets the South China Sea.
(Thinking of the South Musk Sea)
Nationalism is all we've got to push forward space exploration; While there were initially subtexts involving spy satellites and nuclear weapons, the tech has been there for forty years, and forty years ago we stopped making progress and settled into a holding pattern involving the Shuttle and a modest space station in some sort of 'spirit of cooperation' that is earmark- rather than goal-oriented.
I can only hope China's national inferiority complex is intense enough to propel human beings beyond low earth orbit once more, and shame us out of our hyperpower exceptionalism. Yes, shame - Russia can send someone to the ISS and the US cannot - and without the US feeling ashamed of that, there is no Dragon, no Dream Chaser, no Orion.
Without a political space race, there's no resources for this sort of thing except for the passing billionaire.
What about the Google X-Prize for the moon lander? Several teams are competing. There are certainly other ways to push technologies forward. X-Prizes help. Finding other ways to tap into the $15 trillion US economy would help too.
