This is a clip from one of our latest 60-second engine firing tests! The video captures the blue flame signature of our methane-fueled propulsion system, along with perfectly defined shock diamonds.
Behind every successful test is the dedication of our engineering team🚀

Tomorrow night, ESA's JUICE spacecraft will make a close pass by Neptune as seen from the U.S.—and along a narrow path across North America, it will transit directly across Neptune.
JUICE should be around mag 12–13. Here's what the encounter will look like from different cities.

New view from space!
We captured this image of the Chinese Space Station as it passed over the coast of Hawaii.
At 12 cm/px resolution, we can see the expected T-shaped configuration of the CSS, with its solar array wings deployed and all science modules visible: Tianhe, Wentian and Mengtian.

Vous êtes vous déjà demandé comment fonctionnent les rendez-vous spatiaux ?
Comment Crew Dragon ou Soyouz arrivent à approcher tout doucement de l'ISS, alors que tout ça file à plusieurs kilomètres par seconde ?
Je vous explique les bases dans ce thread illustré: 🧵

A happy goodbye is still a goodbye 🥹
Mission accomplished, MTM! 🫡 Thank you for the ride!
Thanks to its solar-powered electric thrusters, MTM carried @ESA's Bepi & @JAXA_en 's Mio to Mercury on the power equivalent of 250 ants! 🐜🐜🐜

ACQUISITION OF SIGNAL CONFIRMED! 🎉🛰️
#BepiColombo telemetry shows the Mercury Transfer Module has successfully separated from the spacecraft stack! ✅
First step of Mercury arrival phase - complete! 👏
Next stop: Mercury orbit insertion for MPO and Mio in November!

Jour 198, orbite 3070– Jamais deux sans trois ! 😀
Troisième sortie dans l’espace en quinze jours ce mardi 1er septembre... Cette fois, ce sera une EVA 100 % féminine, et je me réjouis de partager cette aventure avec Jessica – ce sera sa septième sortie dans l’espace ! 👩🚀👩🚀
Immense gratitude 🫶 envers les équipes qui nous accompagnent une nouvelle fois tout au long de ce week-end de préparation.
Promis, la science du dimanche matin reprend très bientôt !
🎥 @esa / @NASA – Préparatifs pour l'EVA-98 avec @astro_anil. @Astro_Jessica et @astro_hathaway orchestrent les opérations !
#εpsilon • @esaspaceflight • @Space_Station • @nasajohnson • @ESA_fr • @CNES

Je repensais à cette séquence de fin de l'Étoffe des héros
On y voit à la dernière seconde la séparation des 2 moteurs latéraux de l'Atlas. Par contre, ce n'est pas le vol de Gordon Cooper qu'on voit là.

Wanted to give an update on the hotfire anomaly investigation. Progress continues. The anomaly originated at the main oxygen valve on one of the BE-4 engines, which was later confirmed by hardware recovery and inspections. Extensive component-level and engine hotfire tests have been conducted to understand the failure mode better and inform mitigations. The path forward is clear. We're making small modifications to the valve that can be quickly retrofitted to existing engines. We’re manufacturing the updated hardware, which will be ready by the end of this month. In parallel, we're working through the remaining fault tree analysis.

Get ready for a front row seat to Artemis III.
NASA has selected @SpaceX to provide laser communications capabilities from the Orion spacecraft for the mission. They will deliver high-def imagery as astronauts test rendezvous & docking operations between Orion and commercial systems. go.nasa.gov/4pJGMzn

✈️ JUST IN: The X-59 has gone supersonic!
The X-59 achieved supersonic speeds for the first time ever today — a major milestone for NASA’s Quesst mission and an important step toward upcoming flights that will demonstrate its quiet supersonic technology ahead of future community overflights.
Fast now. Quiet soon. 🔊➡️🤫

Ce soir mercredi 22 avril à 21h, je serai la caution "spatiale" d'Acermendax pour discuter d'Artemis II.
Ce sera ma première fois sur Tiktok pour un exercice auquel je ne me suis jamais prêté, auprès d'un public différent.
RdV sur sa chaine Tiktok.
Mardi 22 avril, 21h : l’émission Niveau Critique revient en direct sur TikTok avec la Science Squad.
Au menu : « Artemis et les croyances Lunaires ».
L’invité principal est l’animateur de la chaine -Techniques Spatiales-, et l’antenne est ouverte aux internautes qui doutent de la mission spatiale et des versions officielles.
Venez nous rejoindre et faites savoir qu’on écoutera les argumentaires à l’appui des vérités alternatives
