After 17 years of theoretical and experimental work, Goddard achieved the first successful flight of a liquid-fueled rocket on March 26, 1926. The rocket flew 184 feet in 2.5 seconds and landed in a cabbage patch on his Aunt Effie's farm in Auburn, Massachusetts.
Alfred Nobel obtained this rocket’s-eye view of a Swedish landscape - 1897

“The Blue Marble" Photo of Earth taken on 7 December1972 by the crew of the Apollo 17 spacecraft at a distance of about 45,000 kilometers or about 28,000 miles. . It is one of the most widely distributed photographic images in existence. The image is one of the few to show a fully lit Earth, as the astronauts had the Sun behind them when they took the image. To the astronauts, Earth had the size and appearance of a child's glass marble.
