Hurricane Melissa satellite with lightning. My heart is with Jamaica.

💔

This is a category 5, their largest hurricane in history. It’s likely that Jamaica will be completely demolished.

Who has info on how we can help? Are there reliable mutual aid recipients? Other ideas on how to help?

#IASNG vient d’ouvrir les yeux sur la France !
Depuis son #satellite #MetopSGA1, le nouvel instrument du #CNES a observé pour la 1ʳᵉ fois l’atmosphère pour nous aider à mieux prévoir la météo, suivre la pollution et comprendre le climat. 🌧

IASI-NG ouvre les yeux sur la France | CNES

IASI-NG, le sondeur atmosphérique infrarouge de nouvelle génération développé par le CNES a livré sa première observation, un spectre atmosphérique nous renseignant sur la composition de l’atmosphère.

Illustration du satellite météorologique européen Metop-SG A1 en orbite autour de la Terre. On y voit l’instrument IASI-NG, revêtu d’une structure dorée, observant l’atmosphère terrestre grâce à un faisceau dirigé vers la planète. En arrière-plan, l’espace est parsemé d’étoiles.

Solo para decir que si les parecía bajo el nivel actual de distopia en el que vivimos hay una astrónoma canadiense @sundogplanets que esta muy metida con este tema de Reflecting Orbital, una empresa que pretende poner espejos gigantes en el espacio para puedas contratar luz solar de noche, ignorando todos los desastres a varios niveles que esta supone. Esto deberia estar en la agenda y ser objeto de debate --› https://mastodon.social/@sundogplanets/115345346648445621 #ciencia #astronomia #astronomy #lightpollution #contaminacionluminica #gestionambiental #satellite

#NorthKorea is famously secretive, but a newly released #satellite image from a Seattle-area startup called #Xplore shows what's happening there in hyperspectral detail. https://www.geekwire.com/2025/xplore-hyperspectral-north-korea-satellite/ #space

I’ve spent a significant part of my professional life in the satellite industry, and in recent years I’ve been increasingly troubled by the explosion in development and deployment of large constellations of small satellites in low earth orbit (LEO). This excellent (long read) article sets out all the reasons why, especially the effects on launch capacity, frequency spectrum regulation, and avoidance of physical and electronic interference.

So, one week later, I heard today is indeed the final day of NOAA 15 (an automatic station in the US has only just now returned dead air).

One last APT recording, then - 19-8-2025 9.52.56.

I have packed the antenna away. Those of a more poetic disposition might care to read my final thoughts here - https://open-weather.community/archive/ow3241/

Can someone explain to me what caused the dotted trail? It is the most unusual satellite trail I have ever captured in one of my pictures. (Actually, you can find a very well-defined satellite trail at the bottom left...).

#scicomm #astronomy #astrophotography #satellite #pollution

A raw picture with the red filter of LDN 673. The picture is monochromatic and on the top of the dark nebulae and star field there are two lines: one, on the bottom left, that clearly corresponds to a sattelite passing by; the second, going all the way from the top to the bottom, is not a continuous line, like a "normal" satellite trail, but is a dotted line, which is kind of awkward.

…#Musk’s order was an early glimpse of the #power the magnate now wields in #geopolitics & #GlobalSecurity because of #Starlink, a fast-growing #satellite internet service that barely existed early this decade & now provides connectivity even in remote areas of the world. Even before his brief role as donor & advisor to #Trump, Starlink’s success–& the unrivaled connectivity it offers across the planet–had given Musk increasing #influence w/political leaders, governments & militaries worldwide.

#Musk’s sway in #military affairs in Washington & beyond–through #Starlink’s dominance in #satellite #communications & #SpaceX’s clout in #space launches–has reached a dimension previously limited to #sovereign #governments, alarming some regulators & lawmakers. “Elon Musk’s current global dominance exemplifies the dangers of concentrated #power in unregulated domains,” Martha Lane Fox, a member of Britain’s upper house of parliament, said during a debate earlier this year.
