Tracing Water from Ice Caps to Subsurface Reservoirs Water on Mars is believed to originate from the vast polar ice caps, extending to potential hidden oceans beneath the surface. The journey of these ...

Hints of buried water on Mars have swung between tantalizing and controversial, but one idea keeps resurfacing: lakes could persist if they sit beneath a protective lid of ice. Instead of needing a ...

Changes in Mars’ axial tilt (obliquity) drive shifts between polar ice caps at low obliquity and widespread mid-latitude glaciation at high obliquity. These cycles result in ice accumulating inside ...

Mars’ frozen ice caps may be time capsules for ancient life. Lab experiments show that key building blocks of proteins can survive tens of millions of years in pure ice, even under relentless cosmic ...
