With finalisation of the functional tests for the satellite bus and instrument, we have reached another important milestone. Evaluation of the test data confirmed that everything was nominal. In one of the last tests, the satellite was powered up solely by its internal supply and the external power was switched off. This too was successful, so the satellite was turned off and the wiring to the electrical test equipment was removed – a slightly melancholic moment. The next time we receive a signal from the spacecraft it will be in orbit, having separated from the launcher.

Today, with the commencement of the Abbreviated Functional Test, the final checkout of the radar instrument began. The team is now complete - travelling yesterday from Moscow, additional colleagues from Astrium and the German Research Centre for Geosciences (GFZ) arrived at just the right time. For most of them this is not their first stay here in Baikonur - they previously worked on TerraSAR-X and the facility and the working environment are familiar to them.
