Researchers think that the glass was created when impactors (meteoroids, asteroids or comets) slammed into Mars, superheating the Martian dirt and turning parts of the surface into glass Scientists using NASA's Mars Reconnaissance Orbiter (MRO) were able to see glass on the surface of the red planet using the spacecraft's sens...
