The international space station (ISS) is a huge space mammoth, which weighs 400 tons and moves at an incredible speed of 27,700 km/h. It goes completely around our planet in approximately an hour and a half. Accompanying a scientific mission led by the European Space Agency (ESA), the El Primero Striking 10th Swiss chronograph has just spent 159 days in this superstructure. On May 24th, the Russian flight control centre announced that the spacecraft had made a "gentle landing". Three aeroplanes and 14 helicopters were on standby to ensure a safe landing and to help the three team members disembark as quickly as possible. Amongst them, the European astronaut was wearing the Zenith timepiece. Both are doing fine!
