Bouncing Boulders May Finally Explain How Mars’ Ugliest Moon Got It Stripes

Mars boasts two of the ugliest moons in the Solar System, including Phobos – an oddly shaped, pockmarked moon featuring a distinctive set of stripes. Astronomers have debated the origin of these grooves for decades, but a new computer simulation suggests Phobos’ stripes were made by rolling and bouncing boulders dislodged by a cataclysmic asteroid strike.

Scientists Are Already Planning the Next Mission to Pluto

The Pluto-shaped void in our hearts has yet to be filled by Planet 9, copious amounts of Ben & Jerry’s, or anything. Ever since the summer of 2015, when NASA’s New Horizons performed a six-month-long reconnaissance flyby study of Pluto and its moons, fans of the dwarf planet have wondered if or when we’d ever go back. According to New Horizons principal investigator Alan Stern, he and some other planetary scientists are already drawing up the blueprint for a return trip—and this time, it’d be much more than just a flyby.

A Badass New Theory On the Origin of Mars’s Moons 

Phobos and Deimos, Mars’ lumpy, runty moons, were once pegged as captured asteroids. But the truth is shaping up to be far more interesting. These ruddy satellites could be the lone survivors of a giant impact that eviscerated half of Mars’ surface billions of years ago. Read More >>
