Réponse à l’ #ImageMystère : il s’agit du système d’abandon en vol du vaisseau #Orion pour la mission #Artemis 3. En cas de défaillance lanceur, il propulse la capsule d’équipage loin du #SLS pour sauver les astronautes.

🛰️🌑 Le module de service #ESM fournit par l’ESA du vaisseau #Orion de la mission #Artemis 2 a terminé son inspection finale des couches isolantes extérieures.
Ce module servira à propulser 4 astronautes d'une orbite basse vers la #Lune puis à revenir sur Terre fin 2024

"In new, high-resolution imagery of the star-forming region, scientists spotted worlds that defied explanation, naming them Jupiter Mass Binary Objects."
🌑👩🏼🚀👨🏼🚀 Après la capsule, l’équipage #Artemis2 a rendu visite au module de service #ESM2 fourni par l’ESA au Kennedy Space Center.
Plus tard cette année, il sera connecté via l'adaptateur du module d'équipage (visible en haut) à la capsule pour former le vaisseau #Orion complet avant son voyage autour de la #Lune prévu fin 2024

👩🚀👨🚀 L’équipage #Artemis2 a rencontré hier la capsule #Orion qui doit les emmener pour un voyage de 10 jours autour de la #Lune fin 2024. Lors de la conférence de presse, la NASA (📷) a aussi indiqué que cette date pouvait être décalée, la capsule étant sur le chemin critique d’un planning serré.
As a fan of Kagi Search, I gave Kagi's Orion Browser a try. It's built on Safari's tech, but the ideology is closer to Firefox. Supporting BOTH Chrome and Firefox extensions is a huge win.
My initial impressions of the "public beta" is that it still has a lot of work. Few extensions fully work, ie 1Password doesn't work at all. DOM performance was dramatically worse than Chrome (82 vs 133 on speeDOMeter). Hopefully it continues to improve, but it has a long path ahead. #kagi#orion#browsers
Bonjour 🛰️🌑

CH3+ reacts with a wide range of other molecules and has been theorized to be the cornerstone of interstellar organic chemistry, yet until now has remained undetected.
The discovery vindicates the theory that CH3+ can form in the presence of strong UV radiation. UV radiation is destructive to complex organic molecules, but under the right conditions it can facilitate it. There is evidence that the solar system disk was UV radiated by a nearby star.
Although research published as early as the 1970s predicted the importance of CH3+ in interstellar chemistry, it has previously been virtually impossible to detect. It took a sensitive infrared space-based telescope like JWST to finally detect it. https://esawebb.org/news/weic2315/ #JWST#Orion#CH3+

#PlanetarySociety : #NASA spent $49.9 billion 💰💰💰💰💰 on #SLS and #Orion between 📆 2006 and their first test launch in 2022. Due to “poorly defined requirements, poor contractor performance, and increased material #cost”...
• SLS cost 42.5% 📈 more 💸 than originally projected
• Orion cost is 37.4% 📈 higher 💸
• The EGS program has cost 40% 📈 more 💸 than originally expected
