"Venus" 5 was launched on January 5, 1969. Its design is very similar to that of "Venus" 4, but it is stronger.

During the descent of the lander, 53 minutes of detection data were obtained.

When the lander fell to about 24-26 kilometers from the surface of Venus, it was damaged by atmospheric pressure, and the pressure at this time was 26.1 atmospheres.

"Venus" 6 was launched on January 10, 1969, and reached Venus on May 17 of the same year.

The landing capsule has descended to 10 to 12 kilometers from the surface of Venus.

On August 17, 1970, the Soviet Union launched Venus 7, which reached Venus on December 15, 1970.

The spacecraft's landing capsule can withstand 180 atmospheres of pressure, so it successfully reached the surface of Venus, becoming the first human messenger to reach Venus for fieldwork.

The data returned showed that the temperature was as high as 470 degrees Celsius.

The atmosphere is mainly composed of carbon dioxide, with a small amount of oxygen, nitrogen and other gases.

So far, mankind has lifted the mysterious veil of Venus.

The environment of Venus is complex and changeable. The sky is orange-yellow, and it often rains sulfuric acid. A lightning flash lasts for 15 minutes!

On September 9 and September 14, 1978, the former Soviet Union launched "Venus 11" and "Venus 12", both of which successfully achieved soft landings on Venus and worked for 110 minutes respectively.

Especially in the process of "Venus 12" descending to Venus on December 21, it detected frequent lightning and rumbling thunder over Venus. 1,000 lightning flashes were recorded only in the period from 11 kilometers to 5 kilometers from the surface of Venus. , once the lightning lasted 15 minutes!

The former Soviet Union launched the "Giant" Venus probe on January 24, 1961, and crashed due to a launch vehicle failure during space launch.

On February 12, 1961, the "Venus 1" was tested and launched. The probe that successfully flew to Venus weighed 643 kilograms. The "Venus 2" and "Venus 3" launched on November 12 and 5, 1965. The failure, "Venus 3" weighed 963 kilograms, when it hard landed on Venus, all communication and telemetry signals were interrupted, it is estimated that the instruments and equipment were broken.

Nevertheless, the former Soviet Union scientists believe that there is still gain, because the first battle that can directly "hit" Venus is successful.

On January 12, 1967, the "Venus 4" probe was successfully launched. It arrived at Venus in October of the same year and released a landing capsule to Venus. During the 94 minutes it passed through the atmosphere, the atmospheric temperature, pressure and temperature were measured. chemical components.

In 1969, "Venus 5" and "Venus 6" were launched, and they broke into the atmosphere of Venus again to probe. The probe finally landed on the surface of Venus. Due to the damage of hard landing instruments, it could not detect the surface of Venus.

On August 17, 1970, the "Venus 7" probe was successfully launched. It passed through the dense clouds and dense fog of Venus, braved the high temperature and hot, and achieved the first soft landing on the surface of Venus.

"Venus 7" measured that the atmospheric pressure on the surface of Venus is at least 90 times stronger than that of Earth, and the temperature is as high as 470 ℃.

On September 9 and September 14, 1978, the former Soviet Union launched the "Venus 11 and 12", both of which successfully achieved soft landings on Venus and worked for 110 minutes respectively.

In particular, when Venus 12 descended to Venus on December 21, it detected frequent lightning and thunderous rumblings over Venus, and recorded 1,000 in the period from 11 kilometers to 5 kilometers from the surface of Venus. Lightning strikes, and one lightning strike lasted 15 minutes!

On October 30 and November 4, 1981, the "Venus 13" and "Venus 14" that went to the sky successively, the automatic drilling device carried by the landing capsule went deep into the surface of Venus and collected rock samples.
