Intensity picking up

21. June 2010, 02.22
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).

Mission Control Center in Baikonur up and running

18. June 2010, 09.23
Now it is time for me to report for you as well. I am the representative of the German Space Operations Center, GSOC, in Oberpfaffenhofen, and it is my job to ensure timely transmission of critical information during the launch. I flew from Munich on Monday and have been here for a couple of days now. There is already quite a bit to see and do. We saw the next batch of crew leaving for the ISS boarding buses to the launch site. Hermann Berg has already written about the Soyuz launch and the latest activities with TanDEM-X. My first assignment was yesterday, when the Mission Control Center (MCC) was put into operation.

Two successful launches – that’s motivating!

16. June 2010, 19.41
There were recently two successful launches (our congratulations!) – the payloads of the Prisma and Picard missions were launched together from Yasny. We followed these events via their live streams online. As will be the case with TanDEM-X, a Dnepr launcher was used. Problems with the launcher would likely have affected our launch date. So obviously, we were relieved about the smooth launch. And TanDEM-X is next in line!

Packed and ready for dispatch!

11. June 2010, 08.20
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.

Integration of TanDEM-X with the launcher begins!

08. June 2010, 09.30
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.

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

31. May 2010, 09.26
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.

Safety first in the fuelling hall

20. May 2010, 11.45
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.

TanDEM-X makes progress

17. May 2010, 17.30
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.

TanDEM-X is in Baikonur

13. May 2010, 22.02
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.
