The Aalto-1 is a student satellite project,
the first in Finland. The Aalto-1 project started in the beginning of 2010, when a group of students made a feasibility study of the satellite in the framework of the Space Technology special assignment course. Since then the project has created significant excitement among students and teachers alike. New teaching methods have been applied and a significant interdisciplinary co-operation network inside Aalto University has been created.

The miniature 4 kg satellite is constructed primarily as a student project in extensive collaboration with other Finnish universities and institutes.

Finland's first satellite, the Aalto-1, is an ambitious multi-payload nanosatellite mission. The satellite carries three high end innovative research devices: an imaging spectrometer built by VTT, a radiation monitor jointly constructed by the Universities of Helsinki and Turku and an experimental deorbiting device designed by the Finnish Meteorological Institute. The multi-stage mission aims for in-orbit demonstration of all those new technologies for further utilization in space.



Currently the Aalto-1 is being operated daily, and the Aalto-1 mission has been proven succesful in all areas. The Attitude Determination Control System has been working, and this has allowed photography with the AaSI Hyperspectral Imager. Multiple photographs can be downloaded in a day, thanks to a new packaging algorithm developed by students. The RADMON has also been proven to meet its goals, and it is providing data continuously. The readiness of the Plasma Brake has been confirmed, and it will be used near the end of the mission when de-orbiting experiment of the satellite starts later in 2018. The first year of the satellite has been  success, the first anniversary will be celebrated on the 23rd of June 2018.
