Educational training, testing deployment of 10 m tether for deorbiting and camera. |
| Description |
Test the deployment of a 10 m tether, which is an integral part of the electric solar wind sail development. Take picture of the Earth and, if possible Estonia. The project will also be used to build Estonian infrastructure for future space projects and to educate space engineers. |
