Association of Engineering Students in Rocketry,

by students from KTH Royal Institute of Technology,

in Stockholm, Sweden.

Who we are

ÆSIR is a student rocketry association based at Royal Institute of Technology in Stockholm. We consist of about 30 students, spread over several programmes and degrees - including Engineering Physics, Electrical Engineering and Aerospace Engineering.

The association is focused on rocketry, but is more than just a place where rockets are built. It's a meeting place for people from all over the world with interest in rocketry, where our members get to experience first-hand how technical and cultural differences may affect large international projects.

What we are doing

Project Odin

We are currently preparing for the first launch of Odin in late October 2018, follow us on Instagram or Facebook for more frequent updates!

Odin will be our first sounding rocket, with a thrust of about 3kN. Just like the norse god Odin gave an eye for wisdom, our rocket Odin will give us valuable knowledge on constructing rockets. So far, we have conducted two static firings of our rocket motor and are preparing a third test. Odin schematic

During the fall of 2017, we started up a model rocketry project. The goal is to give our less experienced members, who maybe never been able or gotten a chance to build a model rocket, a leap into what rocket building is all about!

It is also a perfect start to your rocket building career later proceeding to one of our larger projects, such as Odin. More pictures from our model rocket launches we conducted in April 2017 and December 2017 can be found on our Facebook Page or on our Instagram!

International collaborations


During fall 2017/spring 2018 some of our members participated in a collaboration with the the French government space agency CNES as a part of their PERSEUS project. The project was to construct an experiment to fly on their rocket. Our team decided to build a device that would measure the vibrations of the rocket.

The project was finished on time and the whole team later participated in a seminar in Paris. Unfortunatly the launch planned to be at Esrange in Kiruna, Sweden, was postponed until further notice due to problems with the rocket.

Our activities
Social Events

ÆSIR is not only an engineering association - it is also a place to hang out with other like-minded rocketry-interested students.

We welcome everyone to join us just to hang out and learn, not just those with experience in rocketry or engineering. Our members are from all levels of education, so there'll be opportunities to make friends from all over campus.


Moving on, we intend to arrange lectures open for everyone. These lectures will be both by external people and our own members - talking about rocketry related things.

The team of ÆSIR
Our mission

ÆSIR was created to provide a forum for students with an interest in rocketry, where they can develop their passion and knowledge in practical aerospace projects. Our goal is to educate students in rocketry and engineering and give our members real world engineering experience. The activities of the association will further strengthen the position of KTH as one of the leading Aerospace Universities.

Our mission is to become one of the top student organisations for rocket building in the world, by breaking and holding the student rocketry altitude record in Europe (which is currently above 30 kilometers). Ultimately, we intend to reach altitudes beyond the 120 kilometer mark.

Why support us

By supporting ÆSIR, you get the chance to both get your name out there through logo placement on our rockets and to support a group of students in breaking the European record of altitude for student rocketry. We gladly accept any kind of support - funding, equipment or knowledge - anything helps our cause.

Who we are looking for

We are looking for you who have a burning passion for rockets to help build our next rocket! The roles we are mainly looking for at the moment are mainly project managers, group managers and team members. We are also looking to fill the roles of media responsible, IT responsible and external relations responsible.
If you'd like to do something else, you are very welcome to let us know in the below form! We are always open for as many people as possible to join us.
