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

Journal 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

Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.

Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack

Systems Engineering, EarlyView.
ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...

High‐Pressure Synthesis and Chemical Bonding of Mg3BiN

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The anti‐perovskite Mg3BiN is obtained by high‐pressure high‐temperature reaction of Mg–Bi mixture with boron nitride serving as crucible material. The compound is electron precise with essentially ionic bonding, and DOS calculations indicate semiconducting behavior.

Crystal Structures and Magnetic Properties of Coordination Polymer Complexes of Metal Ions With Kojic Acid Ligands

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
One‐dimensional coordination polymers of Cu(II) and Co(II) with kojic acid show distinct chain connectivities revealed by X ray crystallography and exhibit extremely weak magnetic interactions, as supported by magnetic measurements and molecular orbital calculations. The crystal structures and magnetic properties of coordination complexes [Cu(C6H5O4)2]
