The in-orbit results and 
lessons learned of the first Finnish satellite Aalto-1 are briefly 
presented in this paper. Aalto-1, a three-unit CubeSat which was 
launched in June 2017, performed Aalto Spectral Imager (AaSI), Radiation
 Monitor (RADMON) and Electrostatic Plasma Brake (EPB) missions. The 
satellite partly fulfilled its mission objectives and allowed to either 
perform or attempt the experiments. Although attitude control was 
partially functional, AaSI and RADMON were able to acquire valuable 
measurements. EPB was successfully commissioned but the tether 
deployment was not successful.
In this paper, we 
present the intended mission, in-orbit experience in operating and 
troubleshooting the satellite, an overview of experiment results, as 
well as lessons learned that will be used in future missions.
