The European Space Agency (ESA) successfully launched its flagship Biomass satellite on 29 April 2025 at 06:15 local time (11:15 CEST) from Europe’s Spaceport in Kourou, French Guiana, aboard a Vega-C rocket. Developed by Airbus Defence and Space, the satellite separated from the launch vehicle under an hour after liftoff. Shortly thereafter, ESA's operations center in Germany received the first signal from Biomass, transmitted via a ground station in Antarctica, confirming its healthy status in orbit.
