## Why It Matters
Trisat represents a national-level nanosatellite effort for Earth observation operated by an academic institution. As an Earth observation satellite, Trisat contributes to the collection of remote sensing data from orbit, supporting research and educational activities affiliated with the University of Maribor. The project places Slovenia among the countries with dedicated small-satellite platforms, enabling local scientists, engineers, and students to gain hands-on experience in satellite operation, data handling, and mission workflows. Trisat’s launch on 2020-09-03 aboard Vega provided the platform with an internationally recognized COSPAR ID (2020-061J) and a satellite catalog number (46280), integrating it into global space tracking and data systems. The public project website and multilingual Wikipedia presence facilitate access to mission information and outreach, helping communicate scientific and technological capabilities to broader audiences.
