CBS News has a photo taken by NASA's Curiosity rover on Mars, of the Martian sunset. It isn't the way this space enthusiast thought it would look, it's less red, more blue.
The tragedy is that, decades after we put men on the Moon, humans have gone no farther into space. It is as though Columbus returned to Spain, told Ferdinand and Isabella what he found, after which they got busy with other things and left the western hemisphere to its own devices. Shameful.
It appears manned space exploration will be left to billionaire dilettantes like Musk and Branson. Teddy Roosevelt would be outraged at the thought, as would Thomas Jefferson. They were giants, today we're led by small-ball apparatchiks.
