Most other space exploration and colonization plans face concerns about the damaging effect of long-term exposure to fractional g or zero gravity on the human musculoskeletal system. Venus's relative proximity makes transportation and communications easier than for most other locations in the Solar System.
Missions to Venus constitute part of the exploration of Venus. The Soviet Union , followed by the United States , have soft landed probes on the surface. Venera 7 was the first lander overall and first for the Soviet Union, touching down on 15 December 1970.

Interest in astronomy was evident as early as 1638 with the initiation of the first American printing press at Harvard College. In 1639, Stephen Daye began to print in Cambridge, Massachusetts, the first series of almanacs published in the Thirteen American Colonies, An Almanack Calculated for New England, by William Pierce.

Venus is the second planet from the Sun. It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth. Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover.
Mariner 2 (Mariner-Venus 1962), an American space probe to Venus, was the first robotic space probe to report successfully from a planetary encounter. The first successful spacecraft in the NASA Mariner program , it was a simplified version of the Block I spacecraft of the Ranger program and an exact copy of Mariner 1 .
