This video documents the final stages of testing and review for the Smile (Solar wind Magnetosphere Ionosphere Link Explorer) mission, a joint project between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS). It covers the completion of a significant week-long thermal-vacuum test, which identified a need for minor software updates. The video features interviews with key personnel from ESA, CAS, and Airbus, who discuss the challenges and successes of the testing campaign and the international collaboration. The process culminates in the successful qualification and flight acceptance review, a major milestone that officially clears the satellite for its planned launch in Spring 2026.
Smile Mission: Final Testing and Approval
0:18 Thermal-Vacuum Testing: The team completes a critical, week-long thermal-vacuum test on the Smile satellite, a major step in the qualification process.
0:40 Software Updates Required: While the test was largely smooth, it revealed the need for minor software updates, which is considered a normal part of the process.
1:16 Round-the-Clock Monitoring: A CAS thermal engineer notes that the test required 24/7 monitoring, which was tiring but ultimately yielded exciting and successful results.
2:34 International Collaboration Challenges: An Airbus engineer reflects on the initial difficulties of working with different engineering standards, languages, and cultures, but emphasizes that the teams managed to work together effectively toward a common goal.
4:23 Satellite Storage: With testing nearly finished, the satellite is scheduled to be packaged and stored in a monitored clean room until it is transported to the launch site.
5:21 Final Readiness Review: The project holds its qualification and flight acceptance review, the final formal step before the satellite can be shipped for launch.
6:22 Mission Cleared for Launch: The review is successful. Carole Mundell, ESA's Director of Science, confirms that Smile has passed and is on track for launch in 2026.
