Recently the new chairman of the Indian Space Research Organization (ISRO) has announced that the Venus mission will be launched by December 2024.
The objective of this mission is to study the sulfuric acid clouds present in the atmosphere of Venus, which are toxic and corrosive in nature.
Earlier, the National Aeronautics and Space Administration (NASA) announced two new robotic missions to Venus (DaVinci Plus and Veritas).
Today Current Affairs
Major Objectives of the Mission:
To investigate surface process and shallow sub-surface stratigraphy.
No prior observations of the subsurface of Venus have been made so far.
Stratigraphy is a branch of geology that studies the formation of layers and layers of rocks.
To study the composition, composition and dynamics of the atmosphere.
To investigate the interaction of the solar wind with the Venusian ionosphere.
Importance of Mission : The Hindu Analysis
The mission will help to know how Earth-like planets move and what conditions exist on Earth-sized exoplanets (planets orbiting a star other than our Sun).
It will help in modeling the Earth’s climate and act as a warning about how dramatically a planet’s climate can change.
Mission Challenges : The Hindu Analysis
Venus presents different challenges than Mars, given its dense atmosphere and surface activity, which makes it a complex planet.
To understand deeply the instruments need to be carried deep through the atmosphere.
Among the instruments the space agency plans to use on the spacecraft is a high resolution Synthetic Aperture Radar (SAR) that will probe the surface of Venus despite the clouds (which reduce visibility) around the planet.
It refers to a technique for producing high-resolution images. Because of the accuracy the radar can penetrate clouds and darkness, which means it can collect data day and night in any weather.
Prior Missions : The Hindu Analysis
America:
Mariner series 1962–1974, Pioneer Venus 1 in 1978 and Pioneer Venus 2, Magellan in 1989.
Russia:
Venera series of spacecraft 1967–1983, Vegas 1 and 2 in 1985.
Japan:
Akatsuki in the year 2015.
Europe:
Venus Express in the year 2005.
Venus Planet : The Hindu Analysis
It is named after the Roman goddess of love and beauty. It is the second largest planet in terms of distance from the Sun and the sixth largest in mass and size.
It is the second-brightest natural object in the night sky after the Moon, which is probably why it was the first planet known for its motion in the sky in the second millennium BC.
Unlike the other planets in our solar system, Venus and Uranus rotate on their axis clockwise.
It is the hottest planet in the solar system due to its high concentration of carbon dioxide which produces an intense greenhouse effect. Today Current Affairs
A day on Venus is longer than a year on Earth. Venus takes longer to rotate on its axis than it does to complete one orbit around the Sun.
That is, the longest rotation of any planet in the Solar System with one rotation in 243 Earth days.
Only 224.7 Earth days to complete one orbit around the Sun. The Hindu Analysis
Venus has been called Earth’s twin sister because of its similarity in mass, size and density and its relative locations in the Solar System.
No planet gets closer to Earth than Venus; at its closest level, it is the nearest largest body to Earth other than the Moon.
The atmospheric pressure of Venus is 90 times greater than that of Earth.
