The Finnish Space Research Society's "The RocketBoys" team has been busy in recent months. I am one of the team members. The video shows how CanSat rockets are made. These rockets are loaded with tin-sized CanSat satellites that student teams have made during the winter.

The competition will be held in Vaasa from 27 to 30.2025. There, these rockets will be launched to an altitude of about a kilometer. The Rocket Boys team will be handling everything related to the launch for the fourth time.

In Vaasa, the team will also have the opportunity to launch their own rockets. I have built two rockets, named Katana and KMX. The Katana rocket is slightly larger than the CanSat rockets. The diameter of the Katana's body tube is 100 mm, it is 1.90 cm long and it weighs 3 kilograms. In Vaasa, Katana is planned to be launched to an altitude of 1600 meters with a Cesaroni 1016J360 motor.
