Milan Stojanović, a scientific associate at the Astronomical Observatory in Belgrade, has revealed details about Serbia’s upcoming “Mozaik” satellite, the country’s first venture into space. The satellite will not only observe the Sun in the X-ray spectrum—an observation impossible from Earth—but will also include a small camera to capture images of Serbia from orbit.
Stojanović shared with the newspaper “Politika” that the primary goal of the “Mozaik” mission is to gain experience and expertise in satellite technology, from component procurement to launch procedures. This knowledge will be crucial for future projects involving larger spacecraft. The “Mozaik” satellite is classified as a “CubeSat,” a type of small satellite measuring 10x10x10 centimeters, often referred to as nanosatellites due to their modular cubic design.
The satellite will feature a ready-made spectrometer for solar observation, while some components will be manufactured in Serbia. The team will need to assemble the satellite and ensure it meets the rigorous standards required for space conditions. Following extensive testing, the satellite will be launched with the assistance of international partners.
Stojanović indicated that the planned launch window for “Mozaik” is between late 2025 and early 2026, with an expected operational lifespan of two to three years. The mission aims to capture data during the solar maximum, a peak period in the Sun’s eleven-year cycle, to maximize scientific results. The timing and success of the mission will also depend on the satellite service provider.
The project is a collaborative effort involving the Astronomical Observatory, the Faculties of Mechanical Engineering, Mathematics and Electrical Engineering in Belgrade, and the “Mihajlo Pupin” Institute. The development has been underway for approximately two years.
