The truth is hard to understand why NASA has not been so brave to return to Venus for so long. It is true that Venus has always been a difficult virus to investigate because of its cruelty. The surface temperature is up to 471 ° C (lead enough to dissolve lead) and the rotation pressure 89 times greater than that of the earth. The atmosphere contains 96% carbon dioxide. And the planet has black clouds of sulfuric acid. When the Soviet Union discovered World Vena 13 in 1982, it was just 127 minutes before it was destroyed.
And yet, we know that conditions were not always difficult! Venus and the Earth are known to have originated as equals and similar groups, and they all live in the solar system (the area where the potential for water to exist on Earth). But only the Earth inhabited, when Venus was turned into hell. Scientists want to know why. The new members “help us answer this question, why don’t our brothers pass on to us?” says Byrne.
In the last year alone, another major development has encouraged NASA to focus more on Venus’ exploration: the hope of finding life. In September 2020, scientists announced that they could discover the phosphine gas – which is known to be produced by living organisms – in the atmosphere of Venus. These results were extensively studied in the following months, and it is now unclear whether the phosphine reading was actually accurate. But all the excitement sparked a debate that the discovery of celestial life was possible on Venus. This amazing prospect has placed Venus at the forefront of public opinion (and perhaps the opinion of lawmakers who approve the NASA budget.)
The selection of these two new missions “is a clear signal from NASA to the Venus crew, ‘We see you, we know you have been neglected and we will do this,'” said Stephen Kane, an astronomer at the University of California, Riverside. “It’s a great moment.”
DAVINCI + is a summary of research into the Deep Atmosphere Venus of Honored Gas, Chemistry, and Imaging Plus. It is a space shuttle in Venus and a celestial parachute. At 63 minutes, it uses a number of spectrometers to study the atmosphere and its structure. It will also showcase the Venusian landscape to better understand its size and location (and if done well, it will be the first study to paint the world at birth).
VERITAS, short of Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy, is a roundabout way for further research. It can use radar and infrared detectors to see under the planet’s black clouds and see its location and shape.
