Why did it develop differently from Earth? Two new NASA missions to the planet Aphrodite
The US space agency NASA has announced that it will launch two new scientific missions to the planet Aphrodite, but not now. The missions will start during the years 2028 -2030. NASA has indicated that it will study the atmosphere and geological history of Earth's closest planetary neighbor.
The U.S. space agency said it would provide $ 500 million for the development of each of the two missions. The first mission on the planet Aphrodite has been named "Davinci +", while the second mission will be named "Veritas".
According to NASA, the "Davinci +" mission aims to study the composition of the dense atmosphere on this planet to understand how it evolved, while the "Veritas" mission will study the surface of the planet to understand its geological history and why it was developed so differently from Earth.
NASA's last visit to the planet Aphrodite was made 30 years ago with the "Magellan" probe.
Venus, about 12,000 km in diameter, is slightly smaller than Earth. It is the second planet from the Sun and the closest planetary neighbor to Earth. Venus orbits from east to west, unlike all the other planets in the solar system except Uranus.
Venus has a longer day than any other planet in the solar system. It performs one rotation in 243 Earth days. Apart from the Sun and the Moon, Venus is the brightest object in the night sky. She takes her name (Venus) from the Roman goddess of love and beauty.
Its thick atmosphere blocks heat, as in the greenhouse effect, and this makes it the hottest planet in the solar system. Surface temperatures reach 471 degrees Celsius, so much so that they can even melt lead.
But at the level where its clouds with strong acid composition stand, about 50 km above the surface, the temperatures are much milder. The planet's atmosphere consists mainly of carbon dioxide, while clouds of sulfuric acid.
Scientists believe that Venus long ago may have had favorable conditions to allow the evolution of living organisms, although its surface is now seen as completely uninhabitable.
