The possibility of water on Mars has long been a tantalizing prospect for scientists. Now, a fresh look at data from the Spirit rover suggests that significant areas of the planet may have once been covered by water.

The evidence comes from a consolidated Mössbauer spectrum for undisturbed soils from Gusev Crater. The analysis, published in Astrobiology Web, reveals hidden clues about the planet's past.

The findings are part of a broader effort to map Mars' water resources, which could be crucial for future astronaut missions. The question remains: how much water was there, and where did it go?
