SED v1-1 finished and submitted


The Student Experiment Documentation v1.1 is an updated version of the Preliminary Design Review, as the version 1.1 suggests. The updated version contains finer details regarding the experiment and how it is to be executed. 

A lot of work and time has been dedicated to the documentation to derive a proper document worth submitting to the BEXUS officials. 

The document can be downloaded, you can find it in our documents page on this website!

EXIST Exists!


Today we recieved news that EXIST has been selected to participate in BEXUS cycle 10, and will fly on BEXUS 24! So we are now entering into a year-long project, that will let us take our idea and make it real.

The next big milestone now is the Preliminary Design Review, a first version of our Student Experiment Documentation that is due 27th of January. So as not to fall behind on the work neccesary, had already began working towards the PDR, so now we can continue our work with renewed energy.

Christmas break is coming up, and hopefully there will be some time to relax in between all the work. Maybe.

​Happy Holidays!

On this page you will find news about the EXIST project and our progress!

SED v2-1 finished and submitted


The submission of the Student Experiment Document v2.0 got a conditional passfrom the Critical Design Review, meaning that small adjustments had too me made, such as explaining some interface and software aspects more in depth. Overall the report got a good mark.  

A second version of the SED has been submitted with all the changes implemented.

SED v2-0 finished and submitted


The updated version of the PDR, which was submitted in January, has been published on the website. The updated version is the Critical Design Review (CDR). The CDR is a more in-depth description of the experiment and a more detailed one. 

This ambitious team is hard working and will strive to achieve great results and smile while we are at it!

Website is live!


Today we launch our official website! Not only that, but our Twitter and Instagram accounts will start posting very soon as well.

In other news, it's only a week left until we will know if we are chosen for the Bexus project or not. We are hopeful after the selection workshop, and we are already working on the first Bexus document, the Preliminary Design Review (PDR), so that we have enough time to get it done.

This was the first of (hopefully) many updates. Stay tuned to find out if Exist will fly!

Software design completed


 The software design of the EXIST experiment have now been completed. Does this mean that the software team can take it easy now? Unfortunately not. Now the different parts of the software has to be integrated and then tested before we dare to fly it.

SED v1-0 finished and submitted


After many long days of hard work, the first version of our Student Experiment Document, the PDR, has been submitted to BEXUS. 100 pages long, the document contains every small detail about the experiment, and if you want to read it, you can find it in our documents page on this website!

As one deadline is met, the work contiinues toward the next one. During the 20-24 february, Max, Hannah, Lucas, Jonas, and Robert will be in Oberpfaffenhofen, Germany for the preliminary design review presentation and the student training week, and there are many preparations to be made!

Manufacture of our mechanical model!

​Sending scientific instruments into the Earths stratosphere requires some form of enclosure to be designed, built and tested to survive the incredibly harsh climate. In order to achieve this in the most efficient way possible, CAD software is used to design a computer model, where everything can be virtually assembled to find the optimum positioning.

This model takes a lot of time and effort to create

and refine, however just creating a model is simply

not enough! It is also difficult to manufacture and

assemble the model into the finished product.

After a lot of effort, the model was completed

and manufactured at a very affordable price.

Finally, we could see how our computer models

could finally be made into something real! This

was down to the amazing help and expertise we

received from two incredible Swedish companies

NSR (Norrköpings Svets & Reparation

AB) and Progatec AB.

NSR first helped our project by carefully advising on the grade of metals we could use. Choice of materials and material grades can be a very tricky part of any mechanical construction, where materials need the right properties in order to fulfil the given specifications. The second way they helped was creating the templates required for manufacturing. This was achieved by a combination of cutting, surface polishing and overall preparation for the manufacturing process to come.

The manufacturing was then completed by another company, Progatec AB, due to their possession of high tolerance CNC machines and willingness to engage in our student project. Manufacturing is, in short, manipulating stock materials (in our case aluminium and steel) to fit the required model. Some manufacturing examples can include bending, cutting or welding. Progatec AB created our mechanical components from the templates and materials sent by NSR, and took advantage of exciting (expensive!) machinery such as as a waterjet cutter, plate bender and a TIG welder.

We have learned an incredible deal about working with external companies, knowledge that will certainly be a huge help in the future for not only our project, but also our professional lives.

We would like to thank these companies for their huge contribution and ongoing support in our project, without which we wouldn’t have been as far as we are now! 

AGS posts article about EXIST and IRIS


The Atmospheric Science Group (AGS) at Luleå University of Technology (LTU) has written an article regarding the two newly accepted LTU BEXUS projects, EXIST and IRIS.

The IRIS project is a group of close friends to the EXIST group, and we will be sharing work spaces with them during the whole BEXUS project timeline.

SEDv3-0 Submitted


The team submitted the third version out of five Student Experiment Documentation (SED)s. This document is the living document of our

experiment that is constantly being updated with

the latest design, manufacturing or test plans.

This version of the document is associated with a

review that will occur on the 3rd of August. An

SSC expert and organizer from the REXUS/BEXUS

panel will come all the way up north to Kiruna and

visit the EXIST team to see how far we have come

in regarding integration of our different subsystems (Electrical, thermal, mechanical, software...). We are very excited and are therefore working hard to build our experiment!

The Exist Project

Prototype Electronics and Instruments


As of the beginning of the summer

we received the infrasound

detecting instruments for our

experiment. These instruments,

namely four special made

microphone arrays from Japan,

and a low frequency pressure

transducer from Digiquartz,

have arrived here thanks to the

marvelously generous

Professor Yamamoto at

Kochi University of Technology.

We express our greatest gratitude to the excellent international cooperation between the Professor and ourselves which has been vital for this experiment! On the third of August a REXUS/BEXUS organizer and official will visit us in Kiruna to review our experiment progress. Wish us luck!

Photo shows one of the microphone arrays (bottom), the prototype versions of our own four electronic circuit boards (center), the GPS navigation device (upper left), and also our brain-box mini-computer Arduino Due (upper right). These instruments and circuits are just some of the instruments on board our experiment to, which in turn is positioned on board the stratospheric balloon BEXUS24, to fly in October!
