Summary

Story summary

Mars was warmer, wetter, and experienced multiple ice ages, reducing its water.
A team from Okayama University, led by Trishit Ruj, studied craters with water ice described as "time capsules."
The study links axial tilt shifts to long-term glaciation and thawing on Mars.
Volcanic activity may have formed buried equatorial ice, suggesting Mars kept water-rich environments longer and informing future missions.
