Meteor Impacts on Mars Can Excavate its Secrets
Spacecraft orbiting Mars can reveal small features on the planet's surface, but there are only so many things you can see from above. When a meteor strikes the surface of Mars, it can excavate sub-surface material, allowing scientists to study what lies beneath. Researchers have simulated various impacts on Mars, changing the sub-surface material from bedrock to water-ice glaciers, and then calculated what should be visible after an impact, enabling new science.
