Can surface fractures on Earth, Mars, and Europa predict habitability on other planets?
When a mudflat crumbles on Earth, or an ice sheet splinters on one of Jupiter's moons (Europa), or an ancient lakebed breaks on Mars, do these fractures follow a hidden geometric script? Could similar patterns on another ...
