For the Integration Week the mechanical set up of the PATHOS had to be completed. So the team spent some weeks of intensive work to complete the set up and to ensure that the basic functions of the experiment are implemented.
Likewise some more software enhancements where done. In that context the Ground Station appearance changed.
On Thursday we welcomed Simon Mawn, Dieter Bischoff and Julia Grünhage from ZARM in our office to show them the current state of the preparations of our experiment.
We talked about mechanical drawings and the manufacturing of the components’ housings. There was a demonstration of the ground station and how we plan to operate the experiment. Furthermore we presented the electrical components we designed ourselves.

At Thursday 25th June and Friday 26th June the Critical Design Review (CDR) took place.
This time the review focused on our mechanical design and our progress with the onboard software. After a presentation to give the Review Panel an overview of the current state there was another discussion of details with the REXUS/BEXUS experts.
Another topic on Thursday was an Interface discussion. All european teams that will place their experiments on REXUS 20 met to talk about the features of the rocket. They also considered whether the experiments could affect each other when they are all mounted on the rocket.
Today there is an article about our project PATHOS in the weekly news letter of our University.

Mit PATHOS auf dem Weg ins All
We used our first thermal vacuum test to prove, that the components we have choosen as …
- On-board Computer
- Board to run the horizon detection algorithm
… are able to withstand the temperature and pressure conditions that can occure during launch campaign and flight.
The components were heated to 60°C, a temperature that can occure within the rocket during flight. Later they were cooled down to -40°C, what can be ambient temperature during countdown in Sweden.
Additionally the components were under low pressure conditions.
Presentation at Garmin Würzburg Days
Three team members introduced the experiment PATHOS to the staff of Garmin Würzburg. The presentation covered the background of the project in the context of space technology and the technical aspects of PATHOS. The REXUS/BEXUS programme with its purpose and organisation was presented too.
at DLR Oberpfaffenhofen , from 9th to 13th February 2015
The first milestone of our project was the Student Training Week. At the DLR Campus at Oberpfaffenhofen we met the REXUS / BEXUS teams from all over Europe.
Together we attended several lectures about the aspects of REXUS / BEXUS experiments. They were given by experts from the different institutes that are part of the programme.
Furthermore we had our Preliminary Design Review.

Just in time for the release of the first version
of our SED (Student Experiment Documentation)
we can present our mission patch.
Special thanks to bevuta IT GmbH for the design.
PATHOS is selected to be flown during the REXUS 19/20 campaign in spring 2016!
