- Before the Space Age, scientists considered Venus as Earth’s sister planet, perhaps even habitable like our own. The two rocky worlds share nearly the same size and density, and because a thick veil of clouds shrouds Venus’ surface, some hoped that the world next door was a tropical paradise with oceans and abundant vegetation.

Jul 28, 2023 · In the 1960s when NASA and the Soviet space agency started using radar imaging technology to look beneath Venus’ clouds, this perception changed dramatically. Today, we know Venus to be an extremely inhospitable environment.
- Contrary to its name, Venus is a hellish place. Venus is named after the Roman goddess of love and fertility, and before the space age, the perception of the planet was driven by science fiction.
- Venus is still geologically active. The low number of craters on Venus indicates that geologic processes may be recycling aged landscapes into pockets of fresh ground.
- Nasty clouds populate its crushing atmosphere. Venus has a dense atmosphere. When the Venera 4 probe descended through that gassy sheath in the mid-1960s, it measured the composition to be primarily carbon dioxide.
- Venus twirls in a different direction. Almost all planets in our solar system, Earth included, spin counterclockwise on their axes. Venus is the only oddball that pirouettes clockwise.
May 21, 2018 · Slightly smaller than Earth, Venus is our closest planetary neighbor. Despite its proximity, relatively little was known about the planet in the late 1970s, especially its lower atmosphere. Several spacecraft had visited Venus in the 1960s and 1970s to try to unlock some of its secrets.
In 1963, a young Harvard assistant professor named Carl Sagan—still years away from becoming a well-known science communicator—conjectured in the NASA film The Clouds of Venus that the planet’s harsh conditions might only exist in the atmosphere.
Dec 10, 2018 · Dec 10, 2018. Article. Slightly smaller than Earth, Venus is our closest planetary neighbor. Despite its proximity, relatively little was known about the planet in the late 1970s, especially its lower atmosphere. All that changed, though, when the most comprehensive study of the Venusian atmosphere began 40 years ago with the Pioneer Venus project.
Sep 14, 2020 · While Mars has always seemed like the apple of the eyes of American space planners, the Mariner and Pioneer programs of the 1960s and ’70s made time for Venus. Mariner 2 was the first American ...
In the early 1960s, studies conducted via spacecraft demonstrated that the current Venusian environment is extreme compared to Earth's. Studies continue to question whether life could have existed on the planet's surface before a runaway greenhouse effect took hold, and whether a relict biosphere could persist high in the modern Venusian ...
