Magion 4: The first step of independent Czechia into Space
Exactly 30 years ago, the newly independent Czech Republic launched its first satellite, Magion 4, into space. It lifted off from the Plesetsk Cosmodrome in Russia, joining the historic line of Czechoslovak satellites.
Magion 4 and the INTERBALL Mission
The Magion 4 satellite was launched on August 3, 1995, as part of the international INTERBALL scientific mission. It measured the Earth's magnetic and electric fields, observed optical phenomena such as the aurora borealis, and studied interactions between the magnetosphere and ionosphere under the influence of solar wind. The name “Magion” is a fusion of “magnetosphere” and “ionosphere”, quite literally naming the satellite after its research focus.
The satellite ceased active operation in September 1997, but it still orbits Earth today as a silent witness to Czech space history.
The Magion Series: A Czechoslovak Space Legacy
From the first Magion in 1978 to the last in 1996, a total of five satellites in this series were launched. According to Jan Kolář, director of the Czech Space Office, the Magion project was a global rarity — small in size, high in scientific value, and widely respected internationally. Czechoslovakia was thus ahead of its time, anticipating today’s boom in small satellite technology.
Following the end of the Magion era, the MIMOSA satellite was launched in 2001, marking the first mission with entirely Czech participation. But after that came a longer pause.
SATurnin-1: Czechia Returns to Orbit
It wasn’t until 2025 that Czechia made a strong return to the space scene. On January 14, the SATurnin-1 satellite was launched aboard a Falcon 9 rocket. It became the largest and most advanced Czech satellite to date. Developed by VZLU Aerospace in Prague’s Letňany district, SATurnin-1 captures high-resolution images of Earth, processes data using artificial intelligence, and serves both security and civilian purposes.
Many experts contributed to its design and construction — their names are engraved directly onto the satellite’s surface.
Several more Czech space missions are currently in preparation:
- AMBIC – Civilian Earth observation
- QUVIK – Research on cosmic radiation and the formation of heavy elements
- ZLUGEM – Monitoring threats to critical infrastructure
