It set off a lot of interest among people interested in Mars science, plus a bunch of commentary about “what, again?” somehow implying that we only need one announcement of Mars water and that’s that. There were worse reactions, including an incredibly stupid one from a so-called “entertainment” radio talk show host who claimed the announcement was a leftist hoax.
So, I just thought I’d tell you that science doesn’t work the way some people think it does. It’s not a leftist or rightist hoax. Although, I can certainly understand how an undereducated oaf who probably ...
