Gaia, the space observatory, won’t shut down easily now that its mission is over. Shades of Star Trek—TOS episode “The Changling,” “Star Trek: The Motion Picture.” You knew this would be a problem! 😊

www.dlr.deEnde einer Ära – Wissenschaftssatellit Gaia wird abgeschaltetEine Ära geht zu Ende: Der Wissenschaftssatellit Gaia der Europäischen Weltraumorganisation ESA wird am 27. März 2025 mit einem letzten Befehl in den endgültigen Ruhezustand versetzt. Nach mehr als zehn Jahren präziser Himmelsvermessung ist sein Treibstoff aufgebraucht. Daher wurde er in einen stabilen Orbit um die Sonne überführt, sodass er das Erde-Mond-System in den nächsten 100 Jahren nicht wieder erreicht. Die Projektleitung von Gaia ist in Deutschland angesiedelt. Die deutschen Beiträge zur Mission werden von der Deutschen Raumfahrtagentur im Deutschen Zentrum für Luft- und Raumfahrt (DLR) im Auftrag des Bundesministeriums für Wirtschaft und Klimaschutz (BMWK) koordiniert.

To further mark the retirement of the ESA's amazingly successful #Gaia Milky Way surveyor spacecraft yesterday, some pictures taken of it during my visit to EADS Astrium in Toulouse on 3 May 2013, 6.5 months before launch.

1. Me in front of the large silicon carbide torus with its two large rectangular telescope primary mirrors;

2. The torus from below;

3. The huge focal plane with its 106 CCD detectors;

4. The large "top hat" that covers it all.

The complex innards of a spacecraft with a black-wrapped torus and other hardware, some gold struts, and red "remove before flight" tags

Some memorabilia from yesterday’s event at ESOC as the ESA #Gaia spacecraft was deactivated after running out of propellant & moved off L2 into an Earth-trailing solar orbit.

One of these objects might last until the Sun turns into red giant five billion years from now; the other will be lucky to last the weekend 🤷‍♂️🍻

Thanks to my ESA colleagues for the former & the fine folk at Oedipus Brewing in Amsterdam for the latter 🙂👍

The #European #Space Agency #ESA has powered down its #Gaia spacecraft after more than a decade spent gathering data that are now being used to unravel the secrets of our home galaxy. On 27 March 2025, Gaia’s control team at ESA’s European Space Operations Centre carefully switched off the spacecraft’s subsystems and sent it into a ‘retirement orbit’ around the Sun. #SpaceScience #Astronomy #Science esa.int/Enabling_Support/Opera
