From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Tailoring the Melting and Glass Transition Behavior of Zeolitic Imidazolate Frameworks via Ammonium Halide Salts

open access: yesSmall, EarlyView.
Ammonium halide salts serve as inorganic modifiers that lower the melting and glass transition temperatures of zeolitic imidazolate frameworks, enabling centimeter‐scale hybrid glasses and melt processing of otherwise unmeltable ZIF‐8. In situ imaging and pair distribution function analysis reveal salt infiltration, Zn─N bond disruption, and Zn–halide ...

Orbit control of high area-to-mass ratio spacecraft using electrochromic coating

open access: yes, 2010
This paper presents a novel method for the orbit control of high area-to-mass ratio spacecraft, such as spacecraft-on-a-chip, future „smart dust‟ devices and inflatable spacecraft.

Fear or feast: small mammal activity increases in the presence of carcasses despite increased threat of predation by black‐backed jackals

open access: yesWildlife Biology, EarlyView.
Food acquisition is arguably the most important, and among the riskiest behaviours for most mammals. Carcasses are an ephemeral resource for many scavengers, particularly black‐backed jackals Lupulella mesomelas that prey on small mammals. Landscape of fear theory suggests that prey species should reduce their activity in areas of high predator ...
