Since the concept of terraformingâ€”making a planet's environment suitable for human habitationÂâ€”was first proposed, Mars has been one of the primary hypothetical candidates for its application.

Back in the day
Elizabeth II, Queen of the United Kingdom, is the elder daughter and successor of George VI. At age 18, she was made a state counsellor, a confidante of the King. During World War II, she trained as a second lieutenant in the women's services. In 1947, she married Philip Mountbatten, Duke of Edinburgh. They were in Kenya when the King died and Elizabeth succeeded to the throne. Her coronation, on June 2, 1953, was the first to be televised. Where did the coronation take place?

Why did Hardy give up writing novels altogether at the height of his success?
