このコンテンツについて
On this day, October 18th, in 1967, the Soviet Union achieved a remarkable feat in space exploration with the successful mission of Venera 4. This intrepid space probe became the first to transmit data from another planet's atmosphere directly to Earth.
Imagine, if you will, a small metal capsule hurtling through the void of space for 141 days, covering over 350 million kilometers. As it approached Venus, nicknamed Earth's evil twin due to its similar size but drastically different conditions, the excitement at mission control was palpable.
At 04:34 UTC, Venera 4 began its dramatic descent into the Venusian atmosphere. For 93 minutes, this plucky probe transmitted a wealth of information back to Earth, revealing secrets of our mysterious neighbor. It discovered that Venus's atmosphere was primarily composed of carbon dioxide, with traces of nitrogen, oxygen, and water vapor.
But the real shocker came when Venera 4 measured the surface temperature of Venus. Are you sitting down for this? It registered a scorching 462 degrees Celsius! That's hot enough to melt lead, folks. It also recorded surface pressures 75 times greater than Earth's at sea level. Talk about extreme conditions!
While Venera 4 didn't survive to reach the planet's surface, its groundbreaking mission paved the way for future Venus exploration and dramatically changed our understanding of planetary atmospheres.
So the next time you look up at that bright evening star, remember the incredible journey of Venera 4 and the hostile world it helped us discover. It just goes to show that in space exploration, even failure can lead to astronomical success!
