After two years, the Costa Concordia was finally righted, refloated and towed to the safe harbors of Genoa. This is what the rescue mission looked like from the European Space Agency's new Sentinel-1A satellite.
The Sentinel-1A is in fact the first satellite launched as part of Europe's Copernicus environment monitoring programme: it's brand new, and being used to surveil the marine environment, so it was perfect for keeping track of the Costa Concordia. The cruise ship capsized near the island of Giglio in January 2012. It began its journey back to Genoa on July 23rd, arriving there four days later. [ESA]
