    CADSat is an initiative of the European Space Agency that challenges students to 3D design a mini satellite the size of a soda can. Participants will be asked to submit a 3D design made with the design tool of their choice, along with a description of their mission objectives. CADSat is a ‘spin-off’ project of CanSat and is suitable as a beginner project to prepare students to participate in CanSat.
