First Picture of the Earth and Moon in a Single Frame

This picture of the Earth and Moon in a single frame, the first of its kind ever taken by a spacecraft, was recorded September 18, 1977, but NASAs Voyager 1 when it was 7.25 million miles (11.66 million kilometers) from Earth. The moon is at the top of the picture and beyond the Earth as viewed by Voyager. In the picture are eastern Asia, the western Pacific Ocean and part of the Arctic. Voyager 1 was directly above Mt. Everest (on the night side of the planet at 25 degrees north latitude) when the picture was taken. The photo was made from three images taken through color filters, then processed by the Image Processing Lab at Jet Propulsion Laboratory (JPL). Because the Earth is many times brighter than the Moon, the Moon was artificially brightened by a factor of three relative to the Earth by computer enhancement so that both bodies would show clearly in the prints. Voyager 1 was launched September 5, 1977 and Voyager 2 on August 20, 1977. JPL is responsible for the Voyager mission

17th century world map

World map, published around 1664 in Amsterdam, the Netherlands, by Dutch mapmaker Joan Blaeu (c.1599- 1673). The Latin title is Nova et Accuratissima Totius Terrarum Orbis Tabula (new and accurate all world map). Blaeu's maps built on those made by Mercator and Hondius in the late 16th and early 17th centuries. The Blaeu maps emphasized fine art and colours, being the most expensive of the time. Two mapmakers are shown at upper right and upper left, together with a wide variety of mythical beings. The poorly-mapped regions include the far north and south, parts of the Americas (left-hand hemisphere), and the Far East. The western coast of Australia (New Holland) was discovered in 1616

Alexei Leonov, first space walk, 1965

First space walk. Soviet cosmonaut Alexei Leonov (born 1934), outside the Voskhod 2 spacecraft in a spacesuit on 18 March 1965, while orbiting the Earth (in the background). This was the world's first extravehicular activity (EVA), or space walk. Voskhod 2 had launched earlier that day, and Leonov exited the spacecraft at 08:30 UTC. He remained outside for 10 minutes, before trying to re-enter. Because his suit had ballooned while outside, he had to let some of his air out before he could successfully re-enter. Cameras mounted on the airlock were meant to record the space walk, but most had to be abandoned due to the problems with Leonov's spacesuit. The CCCP on Leonov's helmet refers to the USSR
