In brief
Watch live from 16:00 GMT (17:00 CET) on 11 December as the European Service Module separates from Orion and the crew capsule splashes down near Isla Guadalupe in the Pacific Ocean, marking the end of the Artemis I lunar mission.
NASA’s uncrewed Artemis I test flight saw Orion travel around the Moon and farther than any spacecraft designed to carry humans and return them to Earth. Now the spacecraft is on a collision course with Earth to test the reentry, hitting our atmosphere at speeds of 40 times the speed of sound.
Just 40 minutes before splashdown, having delivered Orion safely back to Earth, ESA’s European Service Module (ESM) with its Crew Module Adapter will detach from the crew capsule. As planned, the ESM will up harmlessly in the atmosphere as the Orion Crew Module guides itself through reentry, orienting the capsule with its own thrusters, releasing its parachutes and gracefully splashing down. Recovery teams will collect the capsule.
Artemis is the international lunar exploration programme that is taking humankind to the Moon. This first mission provided a first test of both NASA’s Space Launch System (SLS) and the Orion moonship that was propelled by the ESM’s 33 engines beyond the Moon and into deep space. Future European Service Modules will provide electricity, propulsion and cabin thermal control for astronauts on lunar missions as well as breathable atmosphere and drinking water.
An estimated timeline, the NASA live broadcast will be shown on ESA Web TV 2:

| Communications blackout | 17:20-17:25 | 18:20-18:25 |
| Crew capsule skips on atmosphere | 17:25 | 18:25 |
| Second communications blackout | 17:29-17:32 | 18:29-18:32 |
| Parachutes deploy | 17:38 | 18:38 |

Thanks a lot for all the blog posts. There were more detailed as the NASA Artemis blog (and I used them on my french space blog).
ESA and partners car be proud of the work on the ESM. Congratulations to all the teams
Thank you for this entire series of blog posts! The Artemis 1 updates have consistently been informative and engaging, with enough details to satisfy my engineering curiosity while maintaining a clear, accessible tone. Like another reader who commented earlier, I’ve enjoyed following the journey of Orion and the European Service Module with the ESA more than through NASA’s own site. Congratulations for a successful mission.
