During the last two hours before the launch, we had some uncertainty about the wind conditions because a measurement from the balloons used to check the wind speed at different heights gave an odd reading. The measurement had to be repeated to confirm that the reading was incorrect and that conditions were green for launch.
Finally, the launch took place and everything was perfect: orbit injection within 1 sigma from nominal conditions, immediate deployment of the solar array, smooth connection to the ground with associated Telemetry & Telecommand functions working perfectly.
