Of a truth, it would probably do more to advance science and reduce costs if NASA went head-to-head with China on a vital technology contest like it did way back when against Russia to get a man on the moon.
Now there's a really interesting idea, Alamo-Girl! Put the "competition" back into science...what an idea!
On the other hand, I suppose we could just wait for American science to be overtaken altogether by the "international rat pack" of next-generation physicists now collaboratively forming -- from Israel, Central Europe, India, China, and Russia -- who will probably wind up eating our lunch for us if present trends hold. (So to speak.) IMO FWIW.
