Aalto-1


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, it was launched on 23 June 2017. It is Finland's first student satellite project and indigenously-produced satellite. As of 2019, the satellite is operational.

Project history

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

Design

The solar-powered CubeSat-based satellite will weigh approximately, and has 3 main payloads: a miniature Fabry-Pérot spectrometer, designed by VTT Technical Research Centre, a RADMON-radiation detector developed by University of Helsinki and University of Turku for the study of solar wind conditions in the Earth orbit, and an electric sail, which is designed to deorbit it at the end of its 2-year operational lifespan, with the intent of avoiding the creation of space junk.

Launch

Originally the satellite was to be launched by a Falcon 9-rocket, but the launch suffered multiple delays due to the accidents that plagued the Falcon 9-rocket in 2015 and 2016. The launch was removed from the Falcon 9-rocket, and Aalto-1 was launched on 23 June 2017 by PSLV-C38 rocket from India.
