Um, where are we Americans you ask? We've had at least four rovers rolling around on Mars, the most recent is Curiosity and she's nuclear which means her total sols on Mars will be measured in YEARS.
And tell me, who built and launched the Voyager and Pioneer platforms? Some of which are now at the edge of the solar system.
And who landed SEVERAL men on the Moon? Yeah, we did, in the 1960's and 1970's. Nice to see that China and India are playing catchup now. And I have to wonder, if we got a look at the avionics on the Chinese and Indian platforms I'd bet we find a whole bunch of U.S. originated technology in there.
