Orbiting Geophysical Observatory 1 was launched 1964. Five other Orbiting Geophysical Observatories were launched between 1965 and 1969.

World’s biggest cheese was made in Wisconsin in 1964. Using 170,000 quarts of milk from 16,000 cows, the Wisconsin Cheese Foundation made a block of cheddar cheese 14 ½ feet by 6 ½ feet by 5 ½ feet. It weighed 34,591 pounds. The cheese was driven from Wisconsin to New York to be part of the World’s Fair. The cheese was later eaten. Children could sample some cheddar and other types of cheeses.
