Art in space – or, how to set up a formation

On its launch date, 21 June 2010, roughly 16,000 kilometres separated TanDEM-X from its twin satellite, TerraSAR-X. Now, that distance has shrunk to just 2000 kilometres. The time has come for the relative movement between the two satellites to be slowed down, and for them to be set up for formation flying. To accomplish this, the Flight Dynamics Group at the German Space Operations Center (GSOC) will carry out a total of 10 orbital manoeuvres over the next eight days. read more

Intensity picking up

This place, the German Aerospace Center at DLR Oberpfaffenhofen (close to Munich) has a serious trekkie air. As you walk into the building where the action is tonight, chairs and shiny lights have been set up. This is where the infotainment programme will be streamed live. But take a couple of turns around nondescript corridors, and you’re on the bridge — they actually call it that (hence the trekkie reference). read more

Tests completed - the next TanDEM-X transmission will come from space

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. read more
