Akademische Raumfahrt Initiative Schweiz


ARIS brings together students from Swiss universities fascinated by space exploration. Formed around ETH Zurich, HSLU, and ZHAW, we engage our members in engineering challenges by integrating theory and practice. We do not only build rockets, we embrace the personal development of our members. Together with our partners from industry and academia we aggregate the required knowledge. And on the way there, we educate future engineers and leaders in hands-on project work. Our ultimate goal: to fly a student demonstrator in Low Earth Orbit by 2029!

Together, we believe, we can reach the stars.



Project TELL

At its very first participation at the Spaceport America Cup, ARIS won the Charles Hoult Award for Modeling and Simulations for its technical achievement – one of the ten main awards of the competition. Despite a motor failure and the resulting explosion of the rocket a few seconds into the flight, the project TELL was very well received for its technical and operational excellence.

Project HEIDI

With project HEIDI, ARIS – in the second year of its existence – competed for the second time at the Spaceport America Cup in New Mexico and made the second place in its category of 10’000ft and commercial-off-the-shelf solid motors with a nominal flight. Project HEIDI was a full success.

Project RHEA

As a team of 10 students, project RHEA developed the first ever student-built rocket engine test stand in only one year, which lays the auspicious foundation for future engine development projects. Additionally, the first generation of a hybrid rocket engine was designed, manufactured and tested.

Project EULER

Now, in the third year, project EULER is aiming for the first flight to a height of 30’000ft at the SPAC 2020 in New Mexico. The new team consisting of more than 30 students from 6 different Swiss universities will develop the first ARIS generation of supersonic sounding rockets.

Project IRIDE

The focus project IRIDE is developing the next generation of a hybrid rocket engine. Several test firings with different injector and nozzle configuration led to a peak thrust of almost 8 kN and to firing duration of up to 16 seconds.


In autumn 2020, three new teams started to space career with the aim of launching the rocket PICCARD at the Spaceport America Cup with the self developed hybrid rocket engine by team DAEDALUS. Team PHOENIX will focus on the feasibility study of developing a guided recovery for the upcoming year.

Thesis with ARIS

From now on, there is also the possibility to write a Bachelor-, Semester- or Master thesis in cooperation with ARIS. You can either chose a topic from our project pool or bring in your own ideas. We support you with the knowledge of our active members and alumni, with providing workspace and with our contact to partners from industry.
