Wow - the Musk-Trump-bromance turns into a full-bloom divorce battle.
Collateral damage may be crewed spaceflight, as Musk threatens to decommission the Dragon crewed spacecraft.
I did not see this escalating so fast...

This article confirms that the USA are already testing satellites to track aircraft as a replacement for AWACS. Question is which are the satellites? Likely not the NRO or SDA missions. Unlikely also GEO sats and small sats.

"Trump says Palestinians should leave Gaza permanently and US will ‘take over’ strip"
What the FCK is wrong with this guy? (Question is rhetorical!)
His ideas of diplomacy are equivalent to using a chainsaw for brain surgery!
We, the world, are so screwed!

I wonder, when SpaceX and Tesla will realize, that Elon Musk has become a massive liability for them.

Dear crowd,
does anyone know if the very first RocketLab Electron rocket ('It's a test') carried already the Kick Stage? IIRC, the Kick Stage was only announced on the 2nd flight.

Currently I have listed the 1st flight in my database as having no kick stage, but i still lack a solid confirmation.

Intuitive Machines' Nova-C IM1 lander (Odysseus), the 2nd mission in NASA's CLPS program, has landed on the moon. A weak signal has been received, but it is too weak to transmit data. Let's see, if a communication can be established.

Astrobotics Peregrine lunar lander has suffered shortly after launch a propulsion failure which led to a critical loss of propellants. I think, this likely rules out a lunar landing. :-( But perhaps some engineering data can be gathered.
