On the Anticipation of #Lunar Travel in the Early 20th Century - A Pedagogical Exercise: https://arxiv.org/abs/2605.12582 -> "This article examines, from historical and pedagogical perspectives, Alphonse Berget's anticipation of Earth-Moon travel in Le Ciel (Larousse, 1923), decades before the beginning of the space age. [...] Unlike earlier fictional treatments such as Jules Verne's De la Terre a la Lune, Berget approached space travel using physical reasoning grounded in Newtonian gravitation. [...] His estimated Earth-Moon travel time of approximately 49 hours is of the same order of magnitude as Apollo mission transit times (approx. 72 h)."

Rocket Exhaust Derived Surface Water Migration at Lunar Landing Sites: #Lunar spacecraft exhaust could obscure clues to origins of life: https://news.agu.org/press-release/lunar-spacecraft-exhaust-could-obscure-clues-to-origins-of-life/ - exhaust methane could travel pole-to-pole in under two lunar days, half of it settling in regions potentially harboring original ingredients of earthly life.

"Chang'E-4 (CE4), the first mission to soft-land on the lunar farside, provides a unique opportunity for astronomical observations from an environment shielded from terrestrial radio interference, and thus serves as pathfinder for #LunarFarside radio search for extraterrestrial intelligence (SETI) studies. We present a search for periodic technosignatures using low-frequency radio observations from the CE-4 mission, the first radio #SETI study based on data from on the observation in lunar farside": #Moon ...
