CSE's own Magnus L'Argent wrote this recent article in the JustSpace Alliance newsletter. "The night sky is a powerful unifying force, & recognizing that there is more at stake here than just our research will make us more effective. By reflecting on our responsibility in these conflicts, being honest with ourselves about the true motivations of companies, & allying with groups like these, we have a much better chance of preserving the night sky for future generations."

Agardando a eclipse? Fagan caso aos Clásicos:

"Debería ter coidado de non sufrir o mesmo que lle ocorre á xente que mira o sol durante unha eclipse. Porque algúns deles quédanse cegos, creo, a menos que examinen a imaxe reflectida na auga ou algo semellante."

(Sócrates, segundo conta Platón)

While there was no #Starship launch the #SpaceX webcast contained two unexpected segments, one about a vague plan of a space tourist flight - https://x.com/SpaceX/status/2057602409937912158 - with one such vehicle around Mars, the other in minute 21 of https://x.com/i/broadcasts/1YxNrZwwomNxw about results from the #Starlink Stargaze system described in https://starlink.com/updates/stargaze and https://breakingdefense.com/2026/01/spacex-unveils-stargaze-space-tracking-system/ and https://smallsatnews.com/2026/02/18/spacex-unveils-stargaze-system-to-revolutionize-space-traffic-management/: apparently there are numerous unlisted satellites in LEO which come so close to the Starlinks that cameras on the latter see them as bright objects. How could those objects have been missed by all space surveillance from the ground?

"Missing data is a problem for scientists trying to explain the Earth's climate to politicians and business leaders who make decisions on what to do about climate change. While the data loss is currently small, scientists say the problem will only get worse over time as space debris increases. 'Things will get worse before they get better,' said the NASA scientists in [a] 2018 report that assessed debris maneuvers."

Space debris is forcing satellites to dodge more often — costing us vital science. 'Things will get worse before they get better'

"Each time a satellite has to maneuver to avoid a potential collision, it uses fuel which is a finite and precious resource."

Fai dúas semanas presentouse o nº 54 da revista cultural #Raigame.
Para este número invitáronme a escribir un dos artigos, neste caso sobre os #reloxosdesol na #provinciadeOurense.
Fíxome moita ilusión porque é a primeira vez que publico nunha revista en formato físico e en #galego.

A revista xa está dispoñible en fundacións e centros educativos da provincia ourensán e nas principais bibliotecas de #Galicia.
