A 3D‐printable dual‐mode radiation shielding material is introduced by combining boron nitride nanotubes and single‐walled carbon nanotubes in a stretchable PDMS matrix. The complementary nanotube network enables simultaneous attenuation of electromagnetic interference and neutron radiation while maintaining lightweight, mechanical resilience, and ...

All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Crater Observing Bioinspired Rolling Articulator (COBRA)
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Abstract If a spacecraft loses contact with Earth, ground‐based observatories can collect observations to assist the recovery effort by providing information on spacecraft location and state. Optical observations converted to a light curve of spacecraft magnitude over time show the spin period and/or orientation of the spacecraft.

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Asymmetric Crater Relaxation on an Ice‐Rich Ceres Driven by Insolation
Abstract Ceres has a high ice content within its crust and is the closest dwarf planet to the sun. The resultant high insolation levels at Ceres' surface (in comparison to the outer solar system) leads to high variations in surface temperature, which is dependent on both latitude and orientation of the slope (i.e., equatorward‐ or poleward‐facing).

Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...
