3 – 2 – 1 – Lift-Off

REXUS 15 just had a successful flight.
Our data received on the ground station indicates that everything worked as expected. We were also able to extract all flight data from our SD card. Now it’s time to get a powerful computer and plot some graphics!

You should watch this video in HD and loud sound.

Flight readiness review passed and roll out to launcher

Today morning the teams from EUROLAUNCH/MORABA, DLR, ZARM and ESA fully assembled the payload.

In the afternoon all the student teams performed a successful cold countdown (that means it stopped 2min before lift-off). After that the motor mating and the “roll-out” to the launcher were performed.

Launch is planned on tuesday morning. But before a final Flight Readiness Review (FRR) had to be held. First we went through the launch timeline again. Then every responsible from EUROLAUNCH/MORABA, ZARM, DLR, SSC, ESA and the team leaders had to confirm that their contributions mission are ready.

Looking forward for a successful flight!

First week at ESRANGE

On Monday afternoon, we all travelled from Munich to Kiruna. After arriving at Kiruna Airport, we picked up our rental car and drove to Esrange Space Center. Surprisingly, we found the 40km long way without any navigation system.

After the first night, which can’t be considered a real night, as the sun never set, we had our first meeting at 9am. We unpacked our experiments and did first checks if our experiment were still working. Luckily everything was fine.

In the evening, we visited the radar hill, a hill at Esrange where most antennas are located and where you have the best view for watching the scenery (and later the rocket launch).

On Wednesday morning the Comm checks were carried out. Still everything worked for us so we had free time in the afternoon to visit Kiruna.

While driving to Kiruna we went off-road several times and had hope to photograph some moose. We didn’t see any. At about half the way between Esrange and Kiruna we visited an Icehotel. Sadly it way already melting and closed, but we were able to jump over an “ice-fence” and took some photos from inside.

In Kiruna we went to the local church, the town hall, and have seen two statues. A mine worker and a 1:1 model of a Maxus rocket. That was pretty much it.

Bored by Kiruna’s attractions, everybody was fallen asleep on the way home. Our driver still drove the car securely, but missed the exit to Esrange. After all, we drove into the wrong direction for half an hour. You should know that everything looks quite similar here. Always the same streets, the same trees, the same lakes, the same streets, the same trees, the same lakes.

This morning, we were able to sleep a bit longer. Only our team leader had to attend to the morning meeting at 9am. At 2pm, all RX15 experiments were connected with the rocket’s on-board service module. We undertook a first Bench test including two cold countdowns. Surprisingly, our new extraterrestrial friend Paxi from ESA visited us and kept an eye on our ground station.

Now we are heading over to a hot countdown tomorrow with all experiments screwed together. If everything stays on schedule, we will be ready for launch after the motor mating on Saturday.

On Monday, additional tests are planned. Our first launch slot is scheduled for Tuesday.
