On November 6, the last flyby of NASA's Parker Solar Probe over Venus took place to gain momentum towards its closest trip to the Sun. The gravitational assistance maneuver over Venus will cause the ship to literally brush against the planet, passing 376 km from the surface of Venus, that on Earth would be entering the ionosphere.
The flyby will serve to adjust the trajectory of the Parker Probe that will take the spacecraft to just 6100000 km from the surface of the sun, a record that will be on December 24, 2024, it will be the closest it has ever been to the sun. a ship and it will also be the fastest spacecraft in history reaching 200 km per second, about 720,000 km per hour and that multiplies by three the previous record of the elios 2.
Despite this enormous speed, which would be a good speed to explore the solar system, if it were launched towards the nearest star next to Centauri, it would still take 6,300 years to reach it. We need another method of transportation or another method of propulsion to be able to do so. reach the stars, I hope they discover it soon but what interests us now is the data that can be collected from Venus, because this is not the first flyby over Venus and the Park Solar Probe has made it possible to achieve findings, for example, on 11 July of 2020 during its third flyby the Parker in focused its wispr cameras towards Venus.
These cameras are capable of passing through the dense Venusian clouds, remember that the surface of Venus has a temperature of approximately 465 degrees Celsius.
And we have another news from Venus, it was published on October 28, it is an investigation on the Hasset Bat tessera, I think it is an Egyptian name on Venus, the geographical features except Mount Maxwell, all of them have to be names of goddesses or beings of nature feminine well Venus is logical, it is the planet of love, but it is infernal, you see how tremendous the temperature is on the surface of Venus.
This structure that you are seeing may hold the key to explaining why Venus is the way it is and why Venus is not like the Earth. Let's remember Venus is almost the size of the Earth. It would be a little smaller if we were on Venus and we weren't burn from the heat, nor suffocate from the dense atmosphere with sulfuric acid, we would feel almost like the earth, gravity is just less than 10% less, the difference would be minimal, in terms of gravity.
The composition is also similar in terms of the rocks, etc., it rotates very slowly, the days on Venus are very long, but it is believed that this was due to the process that ended up transforming what could have been the primitive oceans of Venus that vaporized and ended up creating this such a dense atmosphere of CO2 with sulfuric acid and other tremendous and hellish toxic components, right now there is very little water, because unfortunately it has no protective magnetic field and solar winds and solar storms have been drying the planet for billions of years, They have been tearing away the atoms, especially those of hydrogen, which are the lightest, and with this they have been drying out the Venusian atmosphere.
The current discovery has been thanks to a trio of geologists and environmental scientists,
one of them from the University of King Juan Carlos in Madrid Spain, the other from the Lawrence Livermore National Laboratory and the third from the University of Minnesota, Venus has no evidence of impacts from craters more than 300 km in diameter because its surface is renewed Due to geological activity in a similar way to what happens here on Earth, it is very difficult to find ancient craters here, there are some left, but they are very few.
The case of this particular Haasttse-baad turns out to be a gigantic structure, it is about 100 km in diameter and appears to be very old. The researchers compared this structure with another giant impact structure on Jupiter's icy moon Ganymede, which It is the largest Moon in the solar system and they concluded that the structure was produced by two huge asteroid impacts, each about 75 km in diameter that hit the same place and at approximately the same time.
Perhaps it was a colossal double asteroid that existed in the early days or in the youth of the solar system, a colossal double asteroid, the point is that such an impact broke the thin crust of Venus, that is why there is such a curious structure, that structure of rupture causing the mantle material to flow in a magmatic cataclysm and this did occur when Venus had water, if there was a time when Venus had oceans like the Earth because in principle nothing makes us rule out that Venus at least in the beginning had the same evolution than the earth and therefore also had oceans.
This brutal magmatic cataclysm is an impact with a diameter of 1500 km, vaporizing the possible ancestral seas and oceans of Venus with so much heat and so much magma. Venus also receives a little more heat from the sun than the earth and water vapor. It is a powerful greenhouse gas, perhaps its evaporated oceans would cause such a brutal greenhouse effect that it would be impossible for it to cool the atmosphere so that it would rain and the water would transform back into oceans and seas, there would not be enough cold and what it did was enter on the path to becoming the hell it is now.
