Dans le numéro de Ciel&espace actuellement en kiosque, je vous parle longuement de la mission @ec_euclid. Et pour ceux que ça intéresse, le premier article de ce dossier est maintenant accessible en ligne :)

Que vois-je en librairie ? Le nouveau beau livre de Mathieu Grousson sur Euclid, sa conception et ses acteurs :-)

Et bien accompagné par un autre livre :-)

Euclid Reaches L2, Shares its First Test Image https://www.universetoday.com/162631/euclid-reaches-l2-shares-its-first-test-image/ #euclidmission #telescopes #cosmology #galaxies

How can one really be sure that #ESAEuclid is now a real #space 🛰️ mission? Well, it is once it has gone up on the historic named mission board in the control room at #ESA operations center ESOC in Darmstadt, Germany.

And it now has! 🎉🍾

Avrupa’nın uzay teleskobu #Euclid, evrenin karanlık sırlarını keşfetmek amacıyla Cumartesi yerel saatle 11:12’de (GMT 15:12) Florida’nın Cape Canaveral bölgesinden SpaceX Falcon 9 roketiyle başarılı bir şekilde uzaya fırlatıldı. #EuclidMission #ESA #uzay

The #EuclidConsortium would like to thank everyone at #ESA and #SpaceX making this launch of #ESAEuclid possible on this short timescale.

1 year ago we didn't have a launcher, as of today the #EuclidMission is on its way to L2 and great science ahead!.

Liftoff #euclid #euclidmission 🎉 🚀

In case anyone wondering why some of us #exoplanet #scientists are interested in today's launch of #ESAEuclid, here's a link to a recent #WhitePaper that the #EuclidMission Exoplanet Science Working Group posted a few days ago. It explains how Euclid could help the #nasa #RomanMission to test planet formation theories, hunt and confirm the existence and nature of free floating planets, and possibly make the first discovery of #exomoons - moons around #exoplanets

#EuclidMission examinará la luz visible e infrarroja de galaxias distantes mediante dos instrumentos científicos a bordo, el VIS y el NISP.

Estos instrumentos medirán las posiciones exactas y las formas de las galaxias en luz visible y su corrimiento al rojo en luz infrarroja.

#ESAEuclid launch 🚀 now 2️⃣ days away. These were the reactions when a number of #EuclidMission scientists and engineers for the first time encountered the fully assembled spacecraft 🛰️ in February, before shipping to #CapeCanaveral:

@dlr_next das Euklidische Universum und das fragile Gleichgewicht, in dem wir leben, das ist mein Denkanstoß heute.... , danke DLR!
#EUKLID #Euclid #euclidmission

⌛ Countdown, now only 3️⃣ days until Saturday, 1 July, the target launch date 🚀 for #ESAEuclid. Launch time: 15:11 UTC = 11:11am EDT (Cape Canaveral) = 17:11 CEST

More prep completed: the #EuclidMission satellite has been mated with its Falcon 9 adapter onto the so-called "Payload Attach Fitting". With this, Euclid will be encapsulated in the payload fairing.

While writing about #ESAEuclid publication 📖: if you are interested in more #ESAEuclid #cosmology and fundamental #physics then I can recommend the article by our Theory Science Working Group (warning: 300+ pages):

#EuclidMission

Coming Saturday is the target launch date for the #EuclidMission 🛰️. 12 years ago it consisted of an initial concepts and a detailed science case. This was captured in the so-called "Euclid Red Book" 📙, officially the "Euclid Definition Study Report", which by now has collected more that 2600 scientific citations.

An up-to-date description of #ESAEuclid is in the making - until then you can read more about the Red Book in the Euclid Consortium Blog:

👉 https://www.euclid-ec.org/red-book-1200-citations/

⏳ Countdown, 4️⃣ days until #ESAEuclid target launch date 🚀 . Earliest launch possibility: 1 July, 15:11 UTC = 11:11am EDT (Cape Canaveral) = 17:11 CEST.

Anticipation intensifies! 😓 The weather prediction is good ⛅: no hurricanes in sight and no thunderstorms predicted for the launch site in the days around 1 July.

Here's the most recent #ESA picture of the #EuclidMission satellite, after being secured to the Falcon 9 adaptor in Florida:

Did you ask yourself: "What is #Euclid, actually?"

Well, to get an answer we asked this question to scientists and engineers in the #EuclidConsortium: "What is Euclid?"
