ESTCube-1 is the first Estonian satellite and it was built in Estonia by students from Tartu University, Estonian Aviation Academy, Tallinn University of Technology and University of Life Sciences. The project started in 2008 and is now ready for launch. The satellite has been launched on May 7th, 2013. The satellite's payload has been developed in conjunction with Finnish Meteorological Institute and German Space Center (DLR).
The main mission of the satellite is to test the electric solar wind sail, a novel space propulsion technology that could revolutionize transportation within the solar system. As Estonia's first satellite, the project will also be used to build Estonian infrastructure for future space projects and to educate space engineers.
The satellite is a cubesat measuring 10 x 10 x 10 cm and weighing 1.05 kg.
