@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.)

Interesting article featuring the latest research on my favorite object from antiquity, the #AntikytheraMechanism.

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!?

Watching #WorldCupfifa2022 ? Then turn off the telly and #BoycottQatar2022. Over 1200 workers died in #Qatar in preparing for this event. Every game has blood on it. This goes way beyond worker safety, but is a sign of serious #HumanRights violations.
Want another reason? #Iran, whose government is threatening to execute over 10 thousand protesters in custody, is allowed to play. What's up #FIFA?

Short, quick 🎞️ by #esa demonstrating a typical Space Rider mission; from the start on #VegaC to the parachute landing.

Somehow missed this, but worth reposting here.

So the #NASA historical investigation of James Webb came out yesterday. Seems we are still being asked to believe that he was a great administrator but had no knowledge of what was being done on his watch in the name of "policy" and somehow is exempt of all responsibility.
Also, yesterday was int'l #LGBTQSTEMDay. Not a coincidence, so #NASA leadership is slapping the #LGBTQ community in the face with this report. All in keeping with tradition it seems.

It seems a fragment of the original star catalogue of #Hipparcos may have been discovered. Would be a great discovery, marking a milestone of the beginning of quantitative #Astronomy . Another #Palimpsest for the win!

So the #MadeInItaly #cubesat #ArgoMoon has sent some of its first images. It is flying in support of the #Artemis1 mission, tasked with documenting the #Orion spacecraft.

RT @ESAGaia:
The famous bright gamma-ray burst, #GRB221009A, was further investigated and illuminated 20 dust clouds, as described in the thread below👇🏽 Even Gaia could not ignore this burst and measured the particle flux at the focal plane. More details:

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.

Crowded skies = bright skies. We're slowly loosing the night and, with it, our window to the Universe.
