TRISAT is an educational 3U CubeSat satellite mission led by the
University of Maribor, which aims to establish a mutual cooperation
between Slovenian university students and the Slovenian space industry.

TRISAT is manifested on the first Small Spacecraft Mission Service
(SSMS) on a Vega launch vehicle in 2020, with Athena, ION CubeSat
