Mission Design and Early Navigation Operations for the Lunar Trailblazer Mission
Abstract Lunar Trailblazer is a smallsat mission launched on 27 February 2025 as a secondary payload with the Intuitive Machines IM‐2 mission. After insertion into a near‐polar circular orbit around the Moon, the mission's goal was to search and characterize lunar water, primarily looking for ice in permanently shadowed craters and water bound in ...

Abstract Accumulation of dust on the Lunar and Martian surfaces plays a critical role in both surface evolution and human exploration efforts, limiting equipment lifetimes and obscuring optical surfaces. Yet, the underlying physics of surface soiling is still poorly understood.

A Different Position: Protest Medicine and the Limits of Professional Neutrality
ABSTRACT Protests are a persistent feature of contemporary urban life, often producing mass injuries through police repression. Yet the role of medical care in these contexts—especially when provided by informal collectives—remains understudied. Drawing on 21 in‐depth interviews with members of volunteer medical brigades during Chile's 2019–2020 ...

Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

Static recrystallization of shocked calcite in Ries impact breccias
Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia

Recent advancements in ballistic protection - a review
This research review paper describes the historical evolution of protective armor and then delves into current methods of producing effective ballistic protection. It investigates the potential of natural fiber reinforced polymer composites, such as kenaf and ramie. Then, it discusses the exploration of 3D printed body armor, which can take on tailored
