No, Cristobal Colon did not turn up from his grave to visit the continent he discovered. Rather, the Columbus laboratory, Europe's contribution to the International Space Station, is now in the US. The billion-euro, 20-ton module, which will house scientific equipment, will be launched to space and mated to the ISS next year.
Built since the mid-1990s, the Columbus science module was stalled because of the delays in the construction of the space station, as well as by the Columbia Space Shuttle disaster.
