So this involved, for example, removing protective covers from the instruments and antennas. In addition, we also finalised the protective multilayer insulation around critical elements.
In parallel, Khrunichev finalised the multilayer insulation on the Breeze upper stage of the rocket and fixed all the electrical connections between the Breeze and the launch adapter.

Thales Alenia Space then switched on the satellite and did some electrical tests which that everything was all ok.
A meeting between the thermal experts clarified the thermal conditions and settings to be used when the satellite is at the launch pad.
The team also visited the vault to configure the NDIU router for the connections between ESA’s European Spacecraft Operations Centre ESOC, the satellite and our electrical ground support equipment for when the satellite is taken to the launch pad.
By about 16:00, Sentinel-3A was ready ...
