Diurnal Temperature Variability at Latitudinally Distinct Sites on the Moon
Abstract The thermophysical environment of the Moon plays a crucial role for future exploration, resource utilization and also in understanding its geological evolution. While global‐scale surface temperature distributions have been reasonably well constrained through numerical modeling and orbiter observations, recent in situ measurements have ...

Geologic investigations of outer planets satellites [PDF]
Four tests are examined: (1) investigation of volcanism on Io; Interim results of thermal and structural modeling of volcanism on Io are presented, (2) a study of the ancient heavily cratered regions on Ganymede, (3) a geologic comparison of the ...

Abstract Grande Comore, the westernmost island within the Madagascar Comoros Volcanic (MCV) chain, hosts two juxtaposed basaltic volcanoes, Karthala and La Grille, with contrasting lava geochemical signatures and eruption frequencies. Their formation and dynamics have been explained either by a mantle plume or, more recently, as part of a ...

Depth sensitive sampling of implanted species in Genesis Collectors using UV laser ablation and SIMS [PDF]
SIMS profiling of laser abalation pits in CVD diamond implanted with oxygen- 18 shows that homogenised 193nm excimer laser beam can successfully ablate a layer a few nm thick, removing surface contamination without signicant loss of implanted ...

Abstract La Soufrière de Guadeloupe volcano exhibits microseismic activity dominated by volcano‐tectonic repeaters, mainly occurring in swarms clustered in a sub‐vertical conduit beneath the Tarissan acid lake (TAS) at depths less than 800 m. Following the April 2018 earthquake (Mlv 4.1), which likely damaged the dome, swarms intensified and show ...

Electrode erosion in steady-state electric propulsion engines [PDF]
The anode and cathode of a 30 kW class arcjet engine were sectioned and analyzed. This arcjet was operated for a total time of 573 hr at power levels between 25 and 30 kW with ammonia at flow rates of 0.25 and 0.27 gm/s.

Abstract Recently, possible exceptionally young mare volcanic glass beads were discovered in Chang'e‐5 (CE‐5) samples. Isotopic dating suggests an age of approximately 120 Ma, presenting new challenges to existing lunar thermal evolution models. Thus, our research focuses on the source region of Rima Mairan, a branch of Rima Sharp, and its surrounding ...

The present study comprehensively examines the cavitation erosion behaviour of a manganese aluminium bronze alloy (MAB-CU4 alloy) as a function of several parameters (i.e., cavitation angle, cavitation number, time, and stand-off distance), particularly ...

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.
