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

Working‐Class Muscles? Co‐Operative Gyms in Interwar Britain

History, EarlyView.
Abstract The Health & Strength League's network of co‐operative gymnasiums constituted one of interwar Britain's most significant yet overlooked physical culture institutions, affiliating over 800 gyms across Britain and Ireland by 1939. Drawing on Health & Strength magazine's editorial content and reader contributions, this article argues that these ...
