Monday, 14 April – Every milestone in the Biomass mission is special—but encapsulation day stands out as truly unforgettable. For the first time, the satellite appeared in its full flight configuration, free from the protective “red tags” that shield its most sensitive components. And just as suddenly, it was also the last time we would see it.
Encapsulation is a delicate and symbolic step. The satellite, already mounted on its flight adapter, is sealed within the rocket fairing—two protective halves that will shield it on its journey through Earth’s atmosphere. As the fairing closed around Biomass, there was a mix of pride, nostalgia, and anticipation in the air.
Gianluigi Fava, ESA’s Assembly, Integration and Verification Engineer, captured the mood:
“Encapsulating a satellite inside a rocket fairing is always a deeply emotional moment for the team. After years of development, building, testing and dedication, it’s the last time we’ll ever see the satellite with our own eyes.”
Gianfranco Spinella, ESA’s Earth Explorers Launch Services Procurement Coordinator added:
“But the real farewell comes at launch. That’s when we watch all our hard work lift off into space.”
We’re proud. We’re excited. And we’re ready for what comes next.
