📣 C'est déjà demain ! Ce jeudi 5 mars, à partir de 21h00, on vous donne rendez-vous pour "l'espace du débat" sur les enjeux du programme #Artemis. Pourquoi retournons-nous sur la Lune ? Quelle place pour l'Europe ? 📺 youtube.com/live/-sLNvGm_I… et twitch.tv/revesdespace

👩🏻‍🚀 A voir absolument : le documentaire "Des femmes dans l'espace" sur @FranceTV france.tv/documentaires/…

Notre Redac’cheffe a collaboré avec la réalisatrice Elise Le Bivic et @brainworkstv durant la création de cette série qui sera diffusée dimanche 1er mars à 13h15 sur #France2 @FranceTV #femmedelespace #Womeninspace

Look what rolled in this morning! The payload fairing for New Glenn's third launch just arrived at the Integration Facility at LC-36 with @AST_SpaceMobile's BlueBird satellite safely secured inside.

🚀🛰️ Le prochain lancement de #NewGlenn se prépare. Le satellite de télécommunication d'AST Mobile (📷 1&2) a été placé sous coiffe et celle-ci vient d'arriver au bâtiment d'assemblage du LC-36 pour intégration sur le lanceur. Décollage prévu courant mars. 📷3 par Blue Origin

A lire "flux d'Helium" et pas d'hydrogène... Ne pas écrire 2 articles en même temps, on croise les flux 🙃

pas d'hydrogène mais d'Helium bien sûr...🙄

L'administrateur @NASAAdmin vient de l'annoncer "nous allons commencer les préparatifs pour le retour au VAB, ce qui exclura la fenêtre de lancement de mars".  On part sur le créneau d'avril qui démarre le 1er avril #artemisII #moon #espaceetexploration

As an update to my earlier post. - The ICPS helium bottles are used to purge the engines, as well as for LH2 and LOX tank pressurization. The systems did work correctly during WDR1 and WDR2. - Last evening, the team was unable to get helium flow through the vehicle. This occurred during a routine operation to repressurize the system. - We observed a similar failure signature on Artemis I. - The Artemis II vehicle is in a safe configuration, using ground ECS purge for the engines versus the onboard helium supply. - Potential faults could include the final filter between the ground and flight vehicle, located on the umbilical, though this seems least likely based on the failure signature. It could also be a failed QD umbilical interface, where similar issues have been observed. It could also be a failed check valve onboard the vehicle, which would be consistent with Artemis I, though corrective actions were taken to minimize reoccurrence on Artemis II. Regardless of the potential fault, accessing and remediating any of these issues can only be performed in the VAB. As mentioned previously, we will begin preparations for rollback, and this will take the March launch window out of consideration. I understand people are disappointed by this development. That disappointment is felt most by the team at NASA, who have been working tirelessly to prepare for this great endeavor. During the 1960s, when NASA achieved what most thought was impossible, and what has never been repeated since, there were many setbacks. One historic example is that Neil Armstrong spent less than 11 hours in space on Gemini 8 before his mission ended prematurely due to a technical issue. A little over three years later, he became the first man to walk on the Moon. There are many differences between the 1960s and today, and expectations should rightfully be high after the time and expense invested in this program. I will say again, the President created Artemis as a program that will far surpass what America achieved during Apollo. We will return in the years ahead, we will build a Moon base, and undertake what should be continuous missions to and from the lunar environment. Where we begin with this architecture and flight rate is not where it will end. Please expect a more extensive briefing later this week as we outline the path forward, not just for Artemis II, but for subsequent missions, to ensure NASA meets the President’s vision to return to the Moon and, this time, to stay.

After overnight data showed an interruption in helium flow in the SLS interim cryogenic propulsion stage, teams are troubleshooting and preparing for a likely rollback of Artemis II to the VAB at @NASAKennedy. This will almost assuredly impact the March launch window. @NASA will continue to provide updates as they become available.

⚠️⚠️La @NASA envisage de ramener le #SLS au VAB en raison de l'interruption du flux d'hélium dans l'étage de propulsion cryogénique intermédiaire. Il y aura certainement un impact sur la date de lancement en mars. @NASAArtemis #ArtemisII #moon #espaceetexploration

La @NASA vient de l'annoncer. Rendez-vous le 6 mars !!! #ArtemisII #spaceexploration #espaceetexploration

Succès pour le remplissage de la fusée #ArtemisII lors du test de pré-lancement effectué cette nuit pour la mission lunaire. Conférence de presse ce vendredi à 16 h UTC (17h Paris) pour avoir les détails sur la suite du du planning. Lancement début mars ? 🚀 @NASAArtemis

Data centers on the Moon? AI at the edge of space? The next chapter of technology isn't on Earth, it's 238,900 miles away. As the world races to build the infrastructure for the lunar economy, one thing is clear: compute, connectivity, and mobility are the foundation everything else will be built on. That's why we're thrilled to partner with @HPE and its Spaceborne Computer program to advance computing on the lunar surface. As a leader in compute on Earth, who better to partner with than HPE? The lunar economy will need the same high-performance compute, AI, and connectivity. And it will need a way to move all that. At Astrolab, we're building the mobility layer that will power everything on the Moon: deploying hardware, transporting cargo, enabling communications networks, and supporting the systems that will make a sustained lunar presence possible.

C’est le nouvel an chinois et la #CSS a été décorée par son équipage qui envoie ses meilleurs vœux pour l’année du cheval 🐎 @CNSpaceStation

We’ve been getting our rover wheels in the dirt since 2021. Check out a side-by-side of the rendered and real-life Astrolab hardware.

Expliquer l’espace et le rendre compréhensible pour tous, c’est la mission d’ESPACE & Exploration et de notre redac’cheffe Et on souhaite une bonne mission à @Soph_astro 🚀 @esaspaceflight @ESA_fr
