Pacific Ocean
One small step… July 20, 1969.
Apollo 11 was the spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin formed the American crew that landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC. Armstrong became the first person to step onto the lunar surface six hours and 39 minutes later on July 21 at 02:56 UTC; Aldrin joined him 19 minutes later. They spent about two and a quarter hours together outside the spacecraft, and they collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth. Command module pilot Michael Collins flew the Command Module Columbia alone in lunar orbit while they were on the Moon’s surface. Armstrong and Aldrin spent 21 hours, 36 minutes on the lunar surface at a site they named Tranquility Base before lifting o...
The Battle of Tsushima. May 27, 1905.
The Russo-Japanese War was fought during 1904 and 1905 between the Russian Empire and the Empire of Japan over rival imperial ambitions in Manchuria and Korea. The major theatres of operations were the Liaodong Peninsula and Mukden in Southern Manchuria and the seas around Korea, Japan and the Yellow Sea. Russia sought a warm-water port on the Pacific Ocean for its navy and for maritime trade. Vladivostok was operational only during the summer, whereas Port Arthur, a naval base in Liaodong Province leased to Russia by the Qing dynasty of China, was operational all year. Since the end of the First Sino-Japanese War in 1895, Japan feared Russian encroachment on its plans to create a sphere of influence in Korea and Manchuria. Russia had demonstrated an expansionist policy in the Siberian Far...
First evidence of HMS Erebus found. August 15, 1855.
The search by Europeans for a western shortcut by sea from Europe to Asia began with the voyages of Christopher Columbus in 1492 and continued through the mid-19th century with a long series of exploratory expeditions originating mainly in England. These voyages, when to any degree successful, added to the sum of European geographic knowledge about the Western Hemisphere, particularly North America, and as that knowledge grew larger, attention gradually turned toward the Arctic. By 1800, the discoveries had already showed conclusively that no Northwest Passage navigable by ships lay in the temperate latitudes between the Pacific and the Atlantic Oceans. In 1804, Sir John Barrow became Second Secretary of the Admiralty, a post he held until 1845, and began a push by the Royal Navy to comple...
