No. 8 - Second Lander Commissioning Slot
In the last pass of the reporting period the second commissioning slot of ALICE started. In parallel, the ROSINA COPS environmental pressure sensor was switched on in support of ALICE high voltage operations.
On the subsystem side no special activity was performed, with the exception of minor thermal subsystem heaters configuration to adapt to the decreasing distance to the Sun and in preparation of the upcoming pressurization activities.
All activities were executed according to plan. The table below shows a chronology of the main activities in the reporting period:
