Exclusive: 's is building network for agency

Spacex is building a network of hundreds of spy satellites under a contract w/a US intelligence agency, 5 sources familiar w/the program said, demonstrating deepening ties between billionaire entrepreneur 's space company & agencies.

The network is being built by 's business unit under a $1.8B contract signed in 2021 w/the National Reconnaissance Office (), an agency that manages , the sources said.

The plans show the extent of SpaceX's involvement in intelligence & projects & illustrate a deeper investment into vast, low-Earth orbiting systems aimed at supporting ground forces.

If successful, the sources said the program would significantly advance the ability of the government & to quickly spot potential targets almost anywhere on the globe.

The contract signals growing trust by the establishment of a company whose owner has clashed w/the admin and sparked controversy over the use of connectivity in the Ukraine war, the sources said.

Cool new @nature paper just dropped colleagues at suggesting models may have warming about right, when compared to @osi_saf data rather than

"We find that the CMIP6 simulations in the central Arctic, with generally thicker ice and snow, align well with satellite observations ... By contrast, climate reanalyses like ERA5 exhibit widespread warm biases exceeding 2 °C in the same region."

Elon Musk shared on X:
“SpaceX just achieved peak download speed of 17Mb/s from satellite direct to unmodified Samsung Android phone”
Ofcourse it’s all in pilot/experimental stage but the future is clear, internet access, anywhere through Low Orbit Satelites using ordinary smartphones (future models probably). National governments will have less control over mobile networks. Although my guess is it only works outside.

For 21 years I've ran an informative #website on #overfishing.

As an "independent source" it was used by politicians, students, and many everyday people alike.

It was used for #publications & #documentaries, and triggered some inquires where I assisted in shaping national & international political statements. It's been fun & fulfilling 🙂

In today's siloed internet its usefulness is gone. No more days with 5.000 unique visitors & multiple email inquires.

Today is its last day online. 1/2

Overfishing.org contained both an introduction to the issue of #overfishing, and #teaching resources. See attached some evergreens (low resolution, DM me for high res).

There's the "what, why, how" #infographic, #satellite imagery of #BottomTrawling in the Dutch #Waddensea #environment, and a poster with #trawling all around the world.

As I'm #sad to see the website go I've renewed the #domain for one more year and am happy to "donate" it to a good cause. Any interest: DM me.

#ocean #sea

Along the coasts of The Netherlands, Germany and Denmark there lays a shallow coastal sea -with associated wetlands and islands- extremely rich with all types of important sea (it serves as a spawning and nursing grounds for fish) and bird (millions of migratory birds use the mud flats to feed on) life. Large parts of the sea consist of tidal mudflats. The intertidal area is sea during high-tide and dryish land during low-tide. For decades there have been bottom trawling and dredging activities on the Dutch part of the area. As of July 1, 2004 mechanical cockle fisheries have been banned in order to preserve the cockles (and the rich bottom) for the millions of birds. However, some fisheries on mussels (mariculture) and shrimp are still taking place. Here are two low-tide imageres showing the marks / scarves left by various trawling activities. These take years to disappear from visual sight and even longer for the benthic situation to return to the pre-trawling situation. The images are composites from aerial photographs, the location is near the island of Texel.

Modern satellite imagery clearly show the mud trails, distortion and other destruction left by the coastal -shallow water- version of these trawling activities. * trawling imagery from Ecuador, USA (Georgia and Louisiana), Netherlands (Vlieland and Westerschelde), Phillipines, China, Malaysia, Indonesia and Mexico. Satellite images are Quickbird, Landsat and aerial photographs.

Il ERS-2 dell'Agenzia Spaziale Europea, grande quanto un autobus scolastico, rientrerà nell'atmosfera terrestre questa settimana dopo aver concluso la sua missione di osservazione della Terra oltre un decennio fa.

Il satellite 'probabilmente' brucerà nell'atmosfera terrestre mercoledì mattina, con un margine di errore di circa 18 ore.

L'ESA ha affermato che a circa 80 km dalla Terra, il grande satellite si romperà in piccoli pezzI.🙏

BBC: Space debris: 'Grandfather satellite' due to fall to Earth https://www.bbc.com/news/science-environment-68318273

ai6yr,

That is a boring "teenager" satellite.

AO-7 is a "Grandfather Satellite" and it freaking STILL WORKS, folks. Launched in 1974... You can make amateur radio contacts on AO-7.

#grandfather #satellite #hamradio

ai6yr,

Here's some folks making contacts on AO-7 in March of 2022. It's still active right now, per the AMSAT status page. ANYTHING in space that was launched in 1974 and is still working is amazing. https://www.youtube.com/watch?v=o53x03RkD2o
