We are glad and very proud to announce our "Your Message In Space" program.

But wait, what is it?

Did you ever want to get something from outer space? Or wish you could send your words into the vast of the universe? Or maybe you are in love and want to send your beloved a very

special message?


With "Your Message In Space" your wishes could become reality! Thanks to the DLR(Deutsches Zentrum für Luft- und Raumfahrt) and some empty space in our experiment module we have the opportunity to send Your Messages on the sounding Rocket REXUS 16 In Space. 

To participate just follow this Link to YMIS for more information and the form to send us your text.


Please tell everyone who might be interested in this program. We think it is a once-in-a-lifetime opportunity! If you like to share our flyer you can find it here in English and in German(deutsch).



Welcome to the MOXA Teampage!


This website is dedicated to the project Measuring Ozone and OXygen in the Atmosphere, which is part of the REXUS15/16 campaign.

The launch of our experiment from the only european rocket base in Kiruna (Sweden) is scheduled for May 2014. The REXUS rocket will reach an altitude of approximately 100 km (Kármán-Line) and allow us to measure residual gases in the atmosphere layers between 0-100 km above the ground, the Mesosphere and the Stratosphere. The experiment will measure the partial pressures of atomic oxygen, molecular oxygen, carbon dioxide and ozone. The sensors   were developed at the University of Technology Dresden (TU Dresden) in Germany; the FIPEX sensors (atomic oxygen) were already used for measurements in the low earth orbit (LEO) on the International Space Station in 2008.  Especially atomic oxygen is a very important issue in modern space sciences as it is an aggressive corrosive.

MOXA is a precursor experiment for the Cube50 project. In this project, 50 picosattelites with a size of only 10x10x10cm³ which will be developed by students and universities all around the globe, will be launched. One of their three payloads will be FIPEX sensors. The launch of QB50 is currently scheduled for 2015.




[T=-161d] 14.11.2013 Electronic Box

PCB boxThis is our box for all the boards we need. It is easy to demount in case we have to work on the boards very fast. They regulate the power, controll heating of the sensors and handle the measured data.

It sounds simple, but it took a long time to design the PCBs (Printed Circuit Boards). After that there was a loop of testing and redesigning pass trough to come to the current design.






[T=-169d] 06.11.2013 Shiny Module

DLR-moduleOur experiment module, provided by the DLR, has arrived in Dresden. We are going to re-use the bulkhead from the previous TUD Rexus team, CaRu. CaRu was launched on Rexus 11 and researched the influence of milligravity on the creation of Runge pictures, which come to live through the combined effects of capillarity and a chemical precipitate reaction.

We are currently waiting for some manufacturing parts from the TU workshop and the delivery of several commercially available parts. After all necessary elements are assembled, the vibration test will be performed under Nathanael's management.

Due to the fact that some critical components are vertically arranged within the module, they are susceptible to vibrations during takeoff. It is necessary to ensure that these parts are not excited at their resonance frequency. We plan to measure the resonance frequency of this component, therefore we need to place several sensors at specific positions of our module.   

[T=-232d] 11.09.2013 Integration Progress Review (IPR)

On 11. september we had our IPR (Integration Progress Review). First the team leader Alexander Mager and Bastian Klose (responsible person of electronics) had a talk about the current status of our experiment and what we planned to do next. After the visitors Dieter Bischoff and Simon Mawn from ZARM and Alexander Schmidt from DLR-Moraba introduce themselves, we discussed the project status.

[T=-283d] 22.07.2013 Mechanical Meeting

Finally hot Summer has arrived in Dresden. Nevertheless we want to proceed in our rocket project. Here you can see the mechanical Teammembers discussing detailed parts of our rocket module. Hatch things are clear, the electronic box and other little stuff too, but we improoved our inner measure project and so there are a lot details to discuss. Pressure sensor mounting is also still in progress but we think we have found a good solution with a local distributer: check out their website if you want to: Schwiedaem

Meeting of the mechanical Teammembers


[T=-290d] 15.07.2013 Beer break

After a long discussion about all things that are to do the next four weeks and technical detail discussion we enjoy a beer at the "Bierstube" in Dresden.

[T=-301d] 04.07.2013 Team meeting

Weekly Teammeeting at the University Library,

At our first group discussion after the CDR we improved our design and Student Experiment Document (SED) with the helpful critics of the review comitee. The review comitee consistes of experts from DLR, ESA, SSA and ESRANGE that helps the students to develop the experiment.


We discussed a timetable and the work order for electronics and mechanical parts. In addition we introduced our new teammember Nathanael in our experiment design. Nathanael is 21 years old and studies mechanical engineering in the 4th semester. He will help the mechanical team members with the inner chamber and the electronic box.

[T=-415d] 08.02.2013 Preliminary Design Review & Training Week

We have sucessfully performed our Preliminary Design Review and had a great training week at the DLR facility in Oberpfaffenhofen!

There we had the three represants of our team, Alexander Mager (Teamleader), Patrick Geigengack (Mechanical) and Alexander Schultze (Electronics & Software) presented the current design to experts from ESA, DLR and ESRANGEchecked our design in detail, gave us very useful advise and a showed us things we can improve.

[T=-428d] 21.01.2013 Preliminary Definition finished

As today, the Preliminary Definition (PD) of the experiment has been finished. Many major decisions have been made, like the position of the sensors, the latch and the development of the electronic circuitry. This design will now be evaluated in Oberpfaffenhofen at the German Aerospace Centre (DLR) by experts in the next week!
