Helping us on our journey here, and the scientists who work here, is a ship bearing one of the most famous names in Maritime history. Endurance. It's the Royal Navy's Ice patrol vessel. The first Endurance also sailed to the Antarctic back in 1914 - on the famous voyage by Sir Ernest Shackleton to cross the continent. But it, or she, got trapped in the ice and was eventually crushed. He and his team endured 22 months in the Antarctic before finally, and amazingly, reaching safety. The last HMS Endurance also played an important part in the Falklands War - the only naval vessel in the area when it began.
