Cocooned safely within environmentally controlled containers, the satellites were carried across the Atlantic aboard an Ilyushin cargo carrier. The satellites left ESA’s ESTEC Test Centre in Noordwijk, the Netherlands, on Tuesday morning heading for Liège Airport in Belgium. From here they flew to Cayenne in French Guiana via a stop in Oporto Airport in Portugal, arriving at their final destination on Wednesday evening local time.
Once unloaded from the aircraft, the satellites were then driven through the tropical dusk to the cleanroom surroundings of the spaceport nearby Kourou, where they could be safely unpacked to begin the satellite launch campaign.
