The new Royal Research Ship Discovery due to be officially named today by the Princess Royal is the latest in a line of vessels bearing the name that date back to 1602 when the East India Company commissioned the first recorded Discovery to explore the waters now known as the Hudson Strait.
In the 20th Century a new Discovery was specially commissioned for the British National Antarctic Expedition of 1901-04, that included Antarctic heroes Captain Scott and Ernest Shackleton.
