Development and characterization of a regional lunar soil simulant for emirates lunar missions

International Journal of Mining Science and Technology
Lunar soil simulants (LSS) have been pivotal in the success of past and current lunar missions. They have enhanced the design of lander and rover wheels through interaction studies on the lunar testbed under simulated environmental conditions.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Advancing conservation breeding programs for marine invertebrates

Conservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Food System Change, Development, and Vulnerability in Semi‐Agricultural Areas of Tibet

Culture, Agriculture, Food and Environment, EarlyView.
ABSTRACT With social and economic development, food systems have significantly changed on the Tibetan plateau over the last two decades. However, the impact of dietary change on Tibetans and their communities remains less well known. This article examines how food change happens in semi‐agricultural areas of eastern Tibet within the context of ...

Modeling the Reflectance of the Lunar Regolith by a New Method Combining Monte Carlo Ray Tracing and Hapke’s Model with Application to Chang’E-1 IIM Data

The Scientific World Journal, 2014
In this paper, we model the reflectance of the lunar regolith by a new method combining Monte Carlo ray tracing and Hapke’s model. The existing modeling methods exploit either a radiative transfer model or a geometric optical model. However, the measured

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

Divine intimacy, frustration and the madness of the city: Changing transhuman kinship in China

Ethos, EarlyView.
This essay shows the affective resonances of the collision of gods, humans, and rapidly shifting landscapes in a newly urbanized part of Suzhou, China. The first section discusses how ties to spirits are not just metaphors or projections of human kinship, but literal parts of a kinship system that invoke responsibilities of care, based on links of both
