On Friday, the propulsion team from AGG Lampoldshausen got organized in 2 shifts to perform the fueling of the satellite in S3B building. The tank has been loaded with 133 kg of Hydrazine, then pressurized with Helium up to 21 bars. Both activities were completed safely during the day.

The first switch ON of the satellite after the fueling took place right after the S3B facility had been evacuated, as it is an hazardous activity. Remotely from the LBC in S1A building, ADS team ran their automated scripts nominally. The commands to close the latch valves (third safety barrier) were also successfully executed. The satellite was switched OFF and left in a safe configuration over the weekend.

A critical step has been achieved!
