Following NASA’s announcement of two new Venus missions last week, ESA has now also released a new Venus mission EnVision. In other words, in the 2030s, we are preparing to conduct an ultra-comprehensive investigation of Venus. These three probes will tell us about Venus. How is the climate of the country step by step toward hell.
Venus is a terrestrial planet that is similar to Earth in composition, size, mass and volume, and is often considered the twin of the Earth. However, in fact, Venus has a thick atmosphere composed mainly of carbon dioxide (96%). Its surface atmospheric pressure is 92 times that of the Earth, and its average surface temperature is as high as 462°C. It is the hottest planet in the solar system and a hellish world that can melt lead. Scientists don’t understand why Venus and the Earth have such a huge difference in the evolution process.
Although Mars and Venus are on both sides of the earth, compared with Mars, there are obviously fewer instruments for detecting Venus. In the past, Venus prospecting mainly came from the Soviet Union’s contributions from the 1960s to 1980s. In 1970, the Soviet Union’s Venus 7 (Venera 7) first attempted to land on the surface of Venus, but it crashed due to the melting of the parachute, and only 20 minutes of data were transmitted back to the earth; It was NASA’s pioneer Venus Orbiter and ESA’s Venus Express Orbiter that uncovered the cloud structure of Venus’ atmosphere.
In order to explore more of the mystery of Venus, the space agencies of various countries once again set their sights on Venus.
Last week, NASA announced two new missions to Venus between 2028 and 2030. One is called VERITAS, which is an orbiting vehicle orbiting Venus. It will map the surface of Venus with high-definition details for 3D reconstruction. Observe the types of rocks on the surface in detail, hoping to study whether there are active volcanoes on Venus that can release water vapor into the atmosphere.
Another mission, called DAVINCI+, will send a probe through the atmosphere of Venus to measure what gases and elements are present, investigate whether Venus has ever had an ocean, and photograph a feature called Tessera (Tessera) on the surface of Venus. High-resolution photos.
The two missions each received USD 500 million in funding from NASA.
Now, the European Space Agency (ESA) has also announced that it will launch a new Venus mission EnVision in 2031, bringing an overall planetary view of Venus’s core to the upper atmosphere, hoping to study how and why Venus and the Earth have evolved so different appearances.
What exactly has Venus experienced to reach this state? Does it imply that the earth will usher in this fate if it experiences a catastrophic greenhouse effect? Is Venus geology still active? Is it possible that once the ocean was even enough to sustain life? What lessons can we learn from the evolution of Venus? Scientists are about to launch a comprehensive investigation plan on this mysterious planet to solve these problems.
