The russian project to launch an alternative to Starlink is in trouble. It seems there is a credit crunch and not enough money for it in the budget for this year.

President Trump wants to spend $175 billion to build a “Golden Dome” of missile defenses. History has some warnings for the project’s new director. A look at some of the looming hurdles from me and Micah Maidenberg: wsj.com/politics/natio…

Is the 3:1 down-to-upload ratio observed by Jetblue really due to user behaviour or just the result of congested GEO links & clients flooding the uplink with retransmission requests causing a feedback loop? At 10-15% packet loss retransmissions can consume over 50% of bandwidth.

EchoStar said it won't make an interest payment because of an FCC inquiry into its 5G network. The move could potentially set the stage for EchoStar to seek Chapter 11 bankruptcy protection – and blame the FCC for it. lightreading.com/open-ran/echos…

Why is IRIS² being dropped now? 1. It has been non-sensical from the start at every level but killing competition by allowing the entire industry to form a single consortium was Breton's biggest stupidity by far. 2. France prioritizes saving Eutelsat over its satellite builders

Should Trump tax SpaceX for its free use of US government controlled spectrum resources? Musk has never sent a dime to the US government for this critical enabling input to the Starlink business, while the carriers use spectrum acquired at auction, with proceeds sent to the

Globalstar C-3 system accepted for filing by FCC. Good news for Globalstar, one wonders if the timing provides a hint that Apple shouldn't get involved in the 2GHz kerfuffle investors.globalstar.com/news-releases/…
