The weight of an aircraft is distributed all along the aircraft. The fuselage, along with the passengers and cargo, contribute a significant portion of the weight of an aircraft. The center of gravity of the aircraft is the average location of the weight and it is usually located inside the fuselage.
Saturn's rings were discovered in 1610 by Galileo Galilei, although he did not see enough detail to know what they were. In 2004, the Cassini spacecraft began capturing unprecedented images of Saturn's atmosphere and the complex structure of its rings and moons. It is hypothesized that the rings formed when Saturn swallowed one of its moons.
Glenn was preceded in space by two Americans, Alan B. Shepard Jr. and Virgil I. âGusâ Grissom, and two Soviets, Yuri A. Gagarin and Gherman S. Titov. In April 1961, Gagarin was the first man in space, and his spacecraft Vostok 1 made a full orbit before returning to Earth. Less than one month later, Shepard was launched into space aboard Freedom 7 on a suborbital flight. In July, Grissom made another brief suborbital flight aboard Liberty Bell 7.
