Deep water cycle studies have largely focused on subduction of lithosphere formed at fast spreading ridges. However, oceanic plates are more likely to become hydrated as spreading rate decreases.
Thermal modeling suggests that active magmatism in the past few hundred thousand years could account for the presence of a large lake previously hypothesized beneath the Red Planet’s southern ice cap.
Hydrated minerals on near-Earth asteroids offer both scientific revelations and economic incentives for companies looking to refuel satellites with material from nearby space.

Are there indications of extended aqueous processes beyond the period of widespread fluvial activity on Mars?
In Colorado forests, NASA scientists and a multinational team of researchers test the limits of satellite remote sensing for measuring the water content of snow.
New radar observations and refined illumination maps reveal uneven water ice deposits twice the size of those found around the planet’s north pole, suggesting the source may be a recent comet impact.
Research uncovers more of Mars’s past, when flowing water may have been transient before eventually disappearing.
A high-pressure form of ice, trapped within diamonds forged in the lower mantle, suggests that aqueous fluids reside deeper in Earth than we knew.
Curiosity’s two-step heating experiment of mudstone at Gale crater reveals minerals that formed in the presence of water less than 3 billion years ago.
