@rdrimmel
A persuasive article but far from implementation.
I'd like to see an expert opinion.

Oh, you definitely want to click on the video link at the top of this article. (I've always said that the #GaiaMission was about more than just stars.)

The Gaia satellite has been retired, but the #GaiaMission continues.

Science observations have ended for the #GaiaMission, but the satellite is undergoing some end-of-life testing. ESA has reoriented the satellite, so it is much brighter than usual, making it a possible target for small telescopes. Observers from around the world are sharing their images (see link below), and the image below is a rather nice example.

The #GaiaMission, after "10.5 years of science operations, Gaia has made some three trillion observations of about two billion stars.." continues.
Observations have ended but data processing has not! Indeed, it takes years of processing to transform these observations into usable quantities (parallax, stellar magnitude, temperature, metallicity..). Next data release in 2026 will be based on half of these observations. The best is yet to come!

A colleague pointed out to me that a wonderful video was made about #Albireo (my favorite hierarchical system), featuring a paper I published a few years ago. Great intro to a complicated system.

Italian #Astronaut Samantha #Cristoforetti to lead #ESA's new LEO Cargo Return Service program to develope a cargo vehicle with return-to-Earth capabilities, with the potential to evolve into a crewed vehicle. The call to industry has been issued and proposals are due by the end of February!?

ICYMI, we're loosing the night sky.
"When all these #megaconstellations are complete, there will be nowhere on Earth to escape to observe a dark, clean night sky."

Now this is the kind of good news we can use more of. Let's hope other countries follow Chile's example.
