Evidence for the charge disproportionation of iron in extraterrestrial bridgmanite
Science Advances, 2020 We find that the charge disproportionation reaction of ferrous iron occurs in a natural high-pressure environment. Bridgmanite, MgSiO3 with perovskite structure, is considered the most abundant mineral on Earth. On the lower mantle, it contains Fe and Al

Martian biolith: A bioinspired regolith composite for closed-loop extraterrestrial manufacturing
PLoS ONE, 2020 Given plans to revisit the lunar surface by the late 2020s and to take a crewed mission to Mars by the late 2030s, critical technologies must mature. In missions of extended duration, in situ resource utilization is necessary to both maximize scientific ...

Insight into rechargeable batteries in extreme environment for deep space exploration
Carbon NeutralizationSince the beginning of the new century, the objectives of deep space exploration missions targeting celestial bodies such as the Moon and Mars shift from “understanding celestial bodies” to “utilizing celestial bodies.” With respect to the successful ...

Astrophysics with Extraterrestrial Materials
, 2016 Extraterrestrial materials, including meteorites, interplanetary dust, and spacecraft-returned asteroidal and cometary samples, provide a record of the starting materials and early evolution of the Solar System. We review how laboratory analyses of these
