Report for week 26 March to 2 April
Payload commissioning activities continued in the reporting period. The Radio Science Instrument (RSI) commissioning covered the first four passes, followed by the initial activation and commissioning of the MIRO instrument.
The latter included a very complex pointing profile resulting in a triple-spiral scanning of the planet Venus with the +Z axis of the spacecraft, which is also the pointing direction of MIRO. This activity was repeated twice in the reporting period.
On the spacecraft subsystems side several software maintenance activities were carried out, including:
All activities were executed according to plan and in some cases the operations planned for a full night pass could be finished well ahead of time.
The table below shows a chronology of the main activities in the reporting period:
At the end of the last New Norcia pass in the reporting period (DOY 093, 08:00) Rosetta was at 10.6 million km from the Earth. The one-way signal travel time was 35.3 seconds.
