The propellant tanks were pressurized nominally today (05/05/2015) and no leak was detected. As it can be seen on the picture below, a blast shield was placed during the test in S1 as a safety precaution . A second one, on the opposite side of the spacecraft, was also used but cannot be seen from this angle of view.

After the pressurisation phase, Thales technicians were preparing in the S1 airlock the RF mast necessary for the future Antenna Connection Test (ACT).
Depressurisation will be completed tomorrow (06/06/2015). Then the test sequence will continue on the platform and and the payload.
