Nice. Greenland goes with French Eutelsat rather than Starlink for its satellite-based internet connectivity.
(“ditches Starlink” seems a bit exaggerated as apparently they build on an existing Eutelsat coop)

Thanks to RFE/RL for the interview on Chinese space intelligence support to the Russian military in Ukraine. Details are scant but I hope it's useful context for thinking about the mundanity (but probably valuable) ISR support the Russians are getting from the Chinese. w/ @julianasuess.bsky.social
Are China's Spy Satellites A Lifeline For Russia's Struggling Space Intelligence?
The Kremlin has denied that China is providing it with battlefield information, saying it has its own satellites. But experts suggest that, in fact, Russia has a dire need for Chinese assistance.

China's new (?) HQ-29 missile is being touted as an ASAT weapon but what I'm seeing is that it's said to be able to do an exoatmospheric MD intercept which would give it DA-ASAT capabilities. I don't know that it's even been tested though
