Recently, NASA made its announcement to move ahead to explore the planet, Venus. They stated that by 2030, they will at least make their two missions to the planet. Notably, Venus, the neighboring planet to earth, is left unexplored. Thus, there is much to be known about the planet ‘Venus.’
NASA, a few days back announced that its solar system exploration program, two missions have been given the go-ahead. However, NASA has made it clear that it’s both of the missions are bound for Venus. The two ambitious missions will be launched between 2028 and 2030. Since 1990, none of the missions were made to any of the planets. Thus, this is a considerable change in direction for Nasa’s planetary science division.
Venus is a very hostile planet, consisting of loads of sulphuric acid in its atmosphere. The surface temperatures are hot enough to melt lead. The planet is very similar to the planet Earth. However, the earth is all full of carbon trapped in rocks. On Venus, it has escaped into the atmosphere – making it roughly 96 percent carbon dioxide. This has led to a runaway greenhouse effect, pushing surface temperatures up to 750 kelvin.
In 1970, the first-ever landing happened. At that time, the Soviet Union’s Venera 7 crashed due to the parachute melting. Yet, it managed to transmit 20 minutes of data back to Earth. The first surface images were taken by Venera 9, followed by Veneras 10, 13, and 14.
Due to the extreme harsh surface issues and conditions, most of the time the planetary exploration missions have avoided Venus. The high temperature for the planet Venus means a high hiking pressure of 90 bars. Thus, this pressure is harsh enough to instantly crush most planetary landers. It might not come as a surprise, then, that missions to Venus haven’t always gone to plan.
