ISRO Chief S.Somnath has announced that ISRO is planning to send “Shukryaan” to Venus, the second planet of our solar system. He said that ISRO is looking at Venus in a new way. The Venus mission by ISRO is scheduled for December 2024 launch, space and aerospace experts feel that though it is a fascinating mission, it is also expected to be one of the most challenging tasks that the national space agency has ever undertaken.
Venus is not the most welcoming of planets. It is scorching hot because a majority of its atmosphere is composed of carbon dioxide. Temperatures on the surface of Venus, owing to the consequent extreme greenhouse effect, can reach up to 870 degrees Fahrenheit (470 degrees Celsius). The surface is said to be hot enough to melt lead, and dappled with innumerable volcanoes. While most of these volcanoes are believed to be dormant, some may still be active. Venus has an extreme surface air pressure about 90 times higher than the sea level pressure of Earth.
Since ancient times, Venus has always captured the imagination of people. Experts point out that though mythologies present Venus as a beautiful planet, it is completely inhospitable and resembles depictions of hell. This is why Venus has to be studied to understand how the planet was formed if it was hospitable at any point and the factors that may have led to it being inhospitable.
Venus has been an object of great interest and target of observation for millennia. The ancient Babylonians tracked its wanderings through the sky in records that date as far back as 1600 BC. The Greek mathematician Pythagoras was the first to discover that the brightest stars in the morning and evening sky were in fact the same object, Venus. ISRO also wants to examine the Venusian surface, which is covered by dense clouds that make it impossible to view the planet’s surface through a key instrument on the spacecraft—the high-resolution synthetic aperture radar. Venus is not nearly the largest planet of the solar system, its proximity to Earth makes it the brightest of the planets in the sky. It also qualifies as the second brightest object in the night sky, after only the moon.
The distance of Venus from the Sun is about 1082 million kilometers. Its polar diameter is 12,014 km. It does not have any satellite i.e. moon. It is the second planet in the Solar System in terms of distance from the Sun. Due to its structural similarity, it is also called the twin planet of the Earth. It is also the hottest planet in the solar system. Here the temperature reaches 425 ° C, which is enough to melt the lead. It takes about 6 minutes for sunlight to reach Venus. Surprisingly, this is the only planet in the solar system which revolves around the sun the most. There is no weather here, as it is inclined only 2.64 degrees on its axis.
There are mountains, valleys, and hundreds of volcanoes on the planet Venus. Venus is the only planet in the solar system that has the most volcanoes. Although many of them are still quiet. The highest mountain on this planet is Maxwell Montes. It is about 8.8 kilometers high. It is about 8.8 kilometers high. Almost equal to the height of Earth’s Mount Everest.
The atmosphere on Venus is quite dense and toxic, consisting mainly of clouds of carbon dioxide gas and sulfuric acid. The Runaway Greenhouse Effect is seen continuously on the planet Venus. The runaway greenhouse effect occurs when a planet hides more energy from the Sun and then sends it back into space.
