Apollo program, significants missions. Years launched: 1968–72. Country or space agency: US. Designation: 7 through 17. Manned. Events of note: Several unmanned test flights preceded 11 manned Apollo missions, including two in Earth orbit (7 and 9), two in lunar orbit (8 and 10), one lunar flyby (13), and six lunar landings (11, 12, and 14–17) in which a total of 12 astronauts walked on the Moon. Apollo 11, crewed by Neil Armstrong , Michael Collins , and Buzz Aldrin , was the first mission to land humans on the Moon, on 20 Jul 1969. Apollo 13, planned as a lunar landing mission, experienced an onboard explosion en route to the Moon; after a swing around the Moon, the crippled spacecraft made a harrowing but safe return journey to Earth with its crew, James Lovell, John Swigert, and Fred Haise. The six landing missions collectively returned almost 382 kg (842 lb) of lunar rocks and soil for study on Earth. See also: year definition , primitive astronomy

If the ancient Chaldæans gave to the planetary conjunctions an influence over terrestrial events, let us remember that in our own time people have searched for connection between terrestrial conditions and periods of unusual prevalence of sun spots; while De la Rue, Loewy, and Balfour Stewart thought they found a connection between sun-spot displays and the planetary positions. Thus we find scientific men, even in our own time, responsible for the belief that storms in the Indian Ocean, the fertility of German vines, famines in India, and high or low Nile-floods in Egypt follow the planetary positions. And, again, the desire to foretell the weather is so laudable that we cannot blame the ancient Greeks for announcing the influence of the moon with as much confidence as it is affirmed in Lord Wolseley’s Soldier’s Pocket Book. Even if the scientific spirit of observation and deduction (astronomy) has sometimes led to erroneous systems for predicting terrestrial events (astrology), we ow...
