KSat Stuttgart e.V.

Three delegates of the PAPELL team travelled to the DLR site in Bonn to participate in the selection workshop of the Überflieger competition.

The Papell team members: Manfred Ehresmann, Franziska Hild, Nicolas Heinz

Despite the weather conditions the team arrived well at the comfortable hotel. The presentation had another test run before a nice dinner was taken.

The next morning started at ten o’clock with a brief introduction by the Überflieger competition project leader Johannes Weppler followed by the first experiment presentation ELVIS. Here 0.5 cm glass beads should represent 5 cm ice fragments of Saturn’s ring and their collision behaviour is to be monitored.

The next experiment in line was DUST. This experiment serves as demonstration of metal 3D-printing. Here, only the distribution and deposition of metal powder in the printing compartment is observed, no laser will be used.  The metal dust is held in place by a magnetic field.

A promising presentation was held by 3D-Dos. The 3D-Dos experiment uses directional dosimeters based on scintillators which should be used to detect general particle radiation.

FORALEX held the final presentation of the first day. Foraminifera and their calcium carbonate shell growth are to be monitored in micro gravity environment.

After the experiment idea presentations, a staff member of the DLR held a presentation on project management, the formal conduction and boundary conditions of the DLR and ESA.

In the concluding Q&A session the four teams had to answer critical questions by the DLR experts, who represent the jury of the competition. All kinds of questions were asked, which allowed the experts to get to know each project in greater detail.

The day ended with a delicious dinner at the pizza parlour L’Osteria, where exciting and informative conversations on the experiment ideas took place.

Our delegates went to bed early, as our presentation was on the next day, which started at nine o’clock.

The following LEOPaRD team took off with their presentation on a radiometer based on a photomultiplier detector used for the LHC. Team EXCISS tries to produce the basic building blocks of the solar system by arcing trough dust. At 10 o’clock it was the turn of PAPELL. The animations of the not yet release PAPELL video was well received by the audience. ARISE concluded the experiment presentation session, here clumping of charged dust particles are analysed. The group had, among others, some test at the ZARM droptower and showed exciting observations.

Afterwards a staff member of the DLR held a presentation on risk assessment, risk classification and formal conduction of such procedures.

Following the lunch break, the Gerst mission was presented with focus on the mission of spring 2018.

The next session was a Q&A session as on the day before. Concerning our project, the expert questions focused on the potential future application of the ferrofluid pumping technology.

With this the selection workshop concluded and after we had a picture with the kind astronaut Gerhard Thiele, we began our travel back home to Stuttgart.

We thank for the numerous informative and innovative presentations of the other team and wish everybody success in the further selection!
