> difficult to see the Mars announcement as anything but hype
Oh yeah, the announcement is hype. But there is actual work underneath it making real progress in science and engineering that moves us closer to Mars. Some of that, moreover, is work that has limited appeal outside a Martian context.
The real thing is that the moon is a better stepping stone, but Bezos already claimed it so Musk had to out do him, which is why he's shooting for Mars.
