The first Galileo In-Orbit Validation satellite landed at Cayenne Rochambeau Airport in French Guiana on 7 September 2011. Known as Flight Model 2, FM2, it took off by Antonov transport from Thales Alenia Space Italy's Rome facility where it was built. A second IOV satellite, called the Proto-Flight Model, PFM, will soon join it: the two will fly together into orbit on a shared Soyuz ST-B launcher.
