Venus has a harsh climate, so the spacecraft existed only a short time after landing.
Venus is considered the hottest planet in the solar system. With its harsh climate, human discoveries on this planet are quite limited.
While spacecraft are sending more and more images from Mars, high-quality images of the surface of Venus are very limited.
In fact, the best photos of Venus’ surface were taken in the early 1980s by Soviet probes. In the space exploration industry, 4 decades is a long time.

Venus is about 200 million kilometers from Earth, 19 million kilometers further than the Earth-Mars distance.
Besides its harsh climate, Venus also attracts attention due to about the same size as Earth, are both made of earth and rock. This is why many people also call Venus “sister planet” of the earth.

Humans have had missions to explore Venus, but most of them ended in failure. Of the first nine missions, only the 1962 flight used Mariner 2 probe of the American Space Agency (NASA).
At that time, Mariner 2 flew about 32,000 km from the surface of Venus to study basic parameters.
The first time a spacecraft landed on the surface of Venus was in 1966. Venera 3 probe of the Soviet Union crashed onto the planet’s surface after several days of losing contact.
Around 1970, Venera 7 spacecraft first soft-landed on the surface of Venus and continued to transmit data back to Earth. Two years later, the Soviet Union continued to give Vessel Venera 8 landed on Venus.

In 1975, Vessel Venera 9 can also do the same thing. According to PetaPixel, the Soviet Union sent 9 other spacecraft to Mars, the last being Vega 2, which landed in 1984.
NASA, for example, had missions to explore Venus. Pioneer Venus 2 in 1978 for atmospheric studies. To date, this agency has failed to land any spacecraft on the surface of Venus.
By the Planetary Society, The clearest images of Venus’ surface were taken in the early 1980s. Because the Venera 9, Venera 10, Venera 13 and Venera 14 spacecraft.
In addition to black and white and colorized photos, there are also processed images with straight horizons, provided by a community passionate about space research.

Heat and atmospheric pressure create Venus’ harsh climatethe surface temperature ranges from 437 to 482 degrees Celsius, while the average surface temperature of Mars is -63 degrees Celsius, which is easier for spacecraft design engineers.
The atmospheric pressure on Venus is 75 times that of Earth. Therefore, if it does not burn, the spacecraft will also be crushed. Venera 13 is the holding probe The longest record on the surface of Venus is 127 minutes.
Venus’s dense atmosphere prevents humans from observing the surface from space, at least in the visible spectrum. Therefore, the only way to see the surface of Venus is to land on the ground.

Although no spacecraft has landed on Venus, NASA’s Mariner 2 is the first spacecraft to fly by a planet other than Earth.
With a survey duration of 42 minutes, scientists discovered many details about Venus, including its extremely hot atmosphere.
NASA is growing DA VINCI, The spacecraft is expected to reach Venus’ atmosphere in 2031, and two missions will follow a few years later. DAVINCI will focus on the study of the planet’s atmosphere and surface.
At that point, there is still a long way to go before humans can see clearer images on the surface of Venus.
