@Dr_M_Davis @mgubrud @MichaelGemar I don't think people fully appreciate how much launch costs are coming down. Everything that was deemed non-feasible because it cost too much to launch needs to be reassessed. Some of it still will be, some won't.
@M\u Davis博士@mgubrud@MichaelGemar我认为人们并没有完全意识到发射成本下降了多少。因为发射成本太高而被认为不可行的一切都需要重新评估。有些仍然会，有些不会。
