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.

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)."

"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 ...
