members in 9ifly forum speculate that it may happen after 2030, (they are the true expert to me), exactly due to lack of funding in their speculation, the whole appollo project cost 6 billions USD in 70s, and a whole Nimitz aircraft carrier battle group cost 0.5 billion USD back then, also limited scientific achievement could be made in a manned mission, all things that human can do on a alien planet, robot can do it too, and cost much less, manned mission just not cost efficient enough. and China is not a developed country, such huge amount of money can always find a more meaningful way to spend.
