Aalto-1 is a Finnish research nanosatellite, created by students of Aalto University. Based on the CubeSat architecture, it was originally scheduled to be launched in 2013, though it was delayed to autumn 2015,[1] later to May 2016 and finally to the end of 2016 . Upon its launch, it will become Finland's first indigenously-produced satellite.

Project history[edit]

The Aalto-1 project began in 2010 with a feasibility study, which was conducted as part of a university course on space technology.[2] The study was followed by the publication of a preliminary design in 2011.[2] A critical design review of the satellite was conducted in 2012.[2] In all, over 80 students of Aalto University's School of Electrical Engineering were involved in the project.[1]


The solar-powered CubeSat-based satellite will weigh approximately 3 kilograms (6.6 lb),[2] and will carry a miniature Fabry-Pérot spectrometer, designed by VTT Technical Research Centre.[3] The satellite incorporates a modified electrostatic motor (dubbed a "brake tether"), which is designed to deorbit it at the end of its operational lifespan, with the intent of avoiding the creation of space junk.[2]


Aalto-1 is to be launched in the beginning of 2017 by a SpaceX Falcon 9 rocket.[4]
