Packed and ready for dispatch!

11.06.2010

We did it! The new German radar satellite TanDEM-X is packed and prepared for dispatch – the upper stage of the launcher with its precious contents stands ready. This is the result of impressive team performance. A group picture of all those who have worked towards this goal in recent days will not go amiss here. read more

The 'square' has to fit into the round!

10.06.2010

Yesterday was all about fitting the 'square' (the TanDEM-X satellite) into the round (the upper stage of the launcher). With these cross sections, TanDEM-X proves that the old German football saying about the round having to go into the square is not invariably true. Well, at least in space... read more

TanDEM-X: An impression in pictures

08.06.2010

A short, but very up-to-date report, prepared during our lunch break. The TanDEM-X satellite was lifted out of its mechanical handling system and placed temporarily on a tripod. read more

Integration of TanDEM-X with the launcher begins!

08.06.2010

I have now settled myself in Baikonur and become acquainted with everyday issues. As of last Tuesday, I have replaced my colleague Michael Bartusch as the project management representative of the space agency here at the launch site. I will be reporting about the TanDEM-X satellite (TDX) on this blog up until the launch. read more

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

31.05.2010

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

Safety first in the fuelling hall

20.05.2010

TanDEM-X has left the integration facility for its reaction control system tank to be filled with hydrazine over the next few days. To do this, the satellite has been moved to the fuelling station as was reported earlier. Fuelling is a dangerous job, because the propellant used is quite toxic. When you enter the fuelling hall, the sign over the entrance reminds everyone to not forget the dangers. Translated, it reads, "Regardless of how urgent your work is, safety comes first." This is a reference to the devastating Nedelin fuelling catastrophe here in Baikonur in 1960, which took 126 lives. read more

TanDEM-X in cleanroom

TanDEM-X makes progress

17.05.2010

We are now in the second week of our TanDEM-X launch campaign here in Baikonur. The satellite has been installed on its test rig and a quick check shows that the instrument and spacecraft are in good health. Meanwhile, the propulsion and cold gas systems have been pressurised to check that they are leak tight. read more

TanDEM-X is in Baikonur

13.05.2010

It was a long, long way to Baikonur. Already, at the beginning of the trip, the cargo plane – loaded with 37 tons of TanDEM-X and its support equipment in six containers – was delayed for several hours. It was not until 22:45 that we were able to leave Munich. One might have hoped that the stop in Ulyanovsk would be short – but on the contrary, the customs checks were extensive and time consuming. read more

The first mission weblog - welcome to the TanDEM-X blog!

28.04.2010

Right on time for 'shipment' of the German radar satellite TanDEM-X this coming Thursday, 29 April 2010, we are launching the TanDEM-X blog – and looking forward to our first mission weblog on the new platform. The plan at this time is for Mission Manager Stefan Buckreuss and the DLR Communications team to be joined on the blog by colleagues working in the areas of project management, science, mission operations, the ground station network, flight dynamics, radar, calibration and data processing. read more
