Will Mars Be Hit By Comet?

Will a comet strike the planet Mars next year? If it does, what does this mean for NASA’s Mars Program? Image Credit: NASA

We might lose one of the two rovers currently roaming Mars, maybe even one of the orbiters that are presently circling the Red Planet—but not due to age or a […]

Follow the Water? No, Follow the Martian Salt
