He became a master seaman in 1759 and spent most of the next decade surveying around Newfoundland and Labrador. He commanded the Endeavor on his first trip to the Pacific, an expedition to observe Venus for the Royal Society (1768-71). On his return trip he circumnavigated New Zealand, charted the eastern coast of Australia and returned by way of Java and the Cape of Good Hope. His second voyage to the Pacific, commanding the Resolution and the Adventure, took Cook along the northern edge of Antarctica and helped him outline the southern hemisphere; in three years (1772-75) he lost only one crew member. His third and final voyage (1776-79) was an effort to find a passage across the northern part of America. After he was forced to turn back at the Bering Strait, he reached Hawaii in January of 1779
