Correlation between Lunar Surface and Exospheric Sodium: Effects of Albedo-driven Temperature on Multilayer Sodium Reservoirs Rather than Surface Abundance Variations

open access: yesThe Astrophysical Journal
Sodium (Na) is a moderately volatile element in the lunar exosphere, released from the surface through thermal and nonthermal processes. We present a combined analysis of Chandrayaan-2 CLASS surface Na abundance, LADEE Ultraviolet–Visible Spectrometer ...

Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp

open access: yesSmall, EarlyView.
Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review

open access: yesSystems Engineering, EarlyView.
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to
