The paper introduces a new controllable lunar dust simulant, BHLD20, and discusses its preparation, properties, and comparison with existing simulants. The study focuses on the particle size distribution, morphology, modal abundance, and chemical composition of the new simulant, highlighting its potential for use in lunar research and exploration.

These URLs point to various image files (JPEG, GIF) associated with figures, tables, or supplementary materials. The URLs include identifiers like 'gr1.jpg', 'gr2.jpg', etc., suggesting they are part of a structured document with multiple visual elements. The text also includes some metadata such as file sizes and dimensions, indicating the images are formatted for online viewing. The paper discusses the development of a lunar dust simulant called BHLD20, comparing its particle size distribution (PSD) with actual lunar dust samples such as Apollo 11 sample 10084 and Apollo 17 sample 70051. It also references JSC-1Avf, a known lunar simulant with a median particle size of 600-700 nm. The study includes figures illust
