Plants grown in Apollo lunar regolith present stress-associated transcriptomes that inform prospects for lunar exploration

Communications Biology, 2022
Arabidopsis plants were seeded onto lunar soil samples taken directly from the Apollo 11, 12, and 17 missions. Transcriptomic analyses reveal that plants grown in lunar soil differentially express genes associated with salt, metal, and ROS stress.

An Empirical Model to Estimate Abundance of Nanophase Metallic Iron (npFe⁰) in Lunar Soils

Remote Sensing, 2020
Lunar soils gradually become mature when they are exposed to a space environment, and nanophase metallic iron (npFe0) generates within them. npFe0 significantly changes the optical properties of lunar soils and affects the interpretation of the remotely ...

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

BeeRootBot: A Bioinspired Robotic Probe Exhibiting Apical Growth through In Situ Soil Binding

Advanced Intelligent Systems, EarlyView.
This study introduces a novel method for consolidating subterranean exploration pathways in plant‐inspired robots by binding in‐situ soil with beeswax, a biobased material. This simultaneous advancement and wall‐lining process reduces penetration resistance, enhances exploration efficiency, enables communication and resource sharing, and promotes ...

Revealing the Mechanical Characteristics via Kinematic Wave Model for Snake-Like Robot Executing Exploration of Lunar Craters

IEEE Access, 2020
It is extremely difficult to collect deep lunar soil samples during lunar exploration, as the average thickness of lunar soils is very large, and the power of lunar soil sampling systems is inherently limited.

Design and Verification of a Novel Sampling System for Lunar Water Ice Exploration

IEEE Access, 2023
Aiming at the problem that it is difficult to collect the subsurface lunar water ice samples quickly due to the cementation-hardening of ice and soil at extremely low temperature in the permanent shadow regions, a novel lunar water ice sampling system is

Can Hybrid Organisations Solve the Paradox of the Triple Bottom Line, and Does It Need Solving?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how B Corp certification enables hybrid organisations to integrate competing institutional logics of market and social purpose. Through a two‐stage qualitative design combining cross‐sector interviews with B Corps and an in‐depth case study, with a total of 30 participants, we analyse how certification supports hybrid ...
