The Belgium 2018 2 euro commemorative coin marks the 50th anniversary of the launch of the ESRO-2B satellite, the first successful scientific satellite developed by the European Space Research Organisation. The national side features a stylised depiction of the satellite orbiting the Earth, representing the nation's significant contributions to European space exploration and scientific advancement. Below the central motif, the inscription 'ESRO-2B' is clearly visible, flanked by the years 1968 and 2018 to denote the half-century milestone. This design highlights Belgium's long-standing commitment to international cooperation in aerospace research and technological innovation. The coin was issued in 2018 with a mintage of 250,000 pieces.
