There's a comet going really close to Mars. I gather the ESA and NASA are going to try to get the satellites already spying on Mars to take a look at it. I find myself wondering what the Martians are doing. Of course, there's not really much you can do about a comet. Back in the 1800s people would freak out when a comet came close to earth--way more than they are for Ebola. They'd buy comet masks to keep from inhaling comet dust. That's why I wonder if the Martians are freaking out about the approaching comet or simply taking it in stride.
