Czech Rocket Society is an independent society for university students who are interested in cosmonautics and rockets. We want to give them an opportunity to put their studies into practice, but at the same time to develop themselves, to test and experiment. At the same time, we want to take a comprehensive approach to rockets and cosmonautics, which is why, for example, we are interested in the legality of rockets, we participate in educational events and also organize the Czech Rocket Challenge.

The Czech Rocket Challenge is a team competition designed for high school and university students. In this challenge, teams of students* design, test, build and finally launch their rocket. Not only the height reached, but also the advancedness and complexity of the rocket, the sophistication of the report, etc. will be evaluated.
What does this mean? We will give you the engine, but the rest will be up to you! Focus on effective structure that can take the largest water load, and make sure the rocket lands safely! Feel free to join this year's 
CZECH ROCKET CHALLENGE.

* The team must have at least one adult member. In the case of a high school team, this can be a teacher/mentor.
