Is that a little man on Mars in this picture from NASA's Mars Spirit explorer? We didn't even bother to blog this image when we saw it the other day, but tons of British newspapers have seized on it. Sample headline: "Crikey! There's A Little Green Man On Mars!" Actually, my favorite is the one that points out he's naked (gasp!). So what do the experts think?

Says the Bad Astronomy Blog:

That does look like a guy hanging out on Mars, enjoying the 0.01 Earth atmospheric pressure, the 98% CO2 air, the subfreezing cold, and of course, just being four inches tall. Martians are pretty short, it seems. And patient, given its pose.
