  • New findings reveal how terrain influenced Mars’s early surface evolution, allowing regions of stable chemical weathering to develop and permanently trap water and minerals, weakening Mars’s climate feedback and limiting long-term hydrological activity.

  • Photochemical modelling suggests that H2 outgassing from crustal hydration could have supported transient warming episodes on early Mars in a CO2-rich atmosphere with abrupt transitions to cold climate states in a CO-rich atmosphere.

  • Mars’s early climate and surface chemistry varied between a generally cold, oxidizing environment and warmer, more reducing conditions, according to a model of atmospheric evolution driven by stochastic, random injection of greenhouse gases.

  • Through an idealized set of simulations, with a model that incorporates key physics, research reveals dramatic swings between massive rainfall events and extended dry periods in hothouse climates.

  • Gale Crater on Mars has been demonstrated to have once hosted water, but its chemistry is still under debate. Here the authors use mineralogical rock compositions and show the once saline character of Gale Crater—a result of warmer climate periods during the Hesperian period.

  • Terraforming Mars is widely discussed but rarely studied rigorously. This Perspective advocates for more research on the topic, ranging from warming methods to biological engineering, to clarify feasibility, costs, ethics and planetary impacts before any ambitious, large-scale attempts.

  • A three-dimensional global climate model shows that the loss of a planet’s oceans through complete vaporization or evaporative escape to space will occur at considerably higher insolation than previously thought, owing to stabilizing atmospheric effects.

  • Though lessons learned from Earth are frequently applied to other planets, there is much to learn about our own planet from the Solar System and beyond. This Perspective highlights examples from geological and atmospheric sciences in which other planetary bodies have acted as analogues, experiments and archives for the Earth sciences.
