Laboratory construction and curation scheme for returned samples of the chang’e-5 mission

Geoscience Letters, 2022
The analysis of samples returned from a planetary body is important to understand the origin, composition, evolution, and interactions with space or atmospheric weathering of the planet. In particular, pristine rocks, which are not affected by weathering,

Experimental study on electrostatic migration of different mineral particles composing lunar dust under electron irradiation

Frontiers in Astronomy and Space Sciences, 2023
Dust electrostatic migration is one of the primary causes of dust events on the surface of airless celestial bodies, which can result in multiple dust phenomena, including lunar horizon glow and dust pools, and also offer crucial insights into the ...

Towards an integrated scientific and social case for human space exploration [PDF]

, 2004
I will argue that an ambitious programme of human space exploration, involving a return to the Moon, and eventually human missions to Mars, will add greatly to human knowledge. Gathering such knowledge is the primary aim of science, but science's compart-

Decreasing extents of Archean serpentinization contributed to the rise of an oxidized atmosphere

Nature Communications, 2021
Throughout the Archean, H2 generation via low-temperature ultramafic serpentinization likely helped prevent atmospheric O2 accumulation and continued until the abundance of ultramafic rocks diminished setting the stage for the Great Oxidation Event.
