Nicknamed theEvening Star, Venus has always intrigued scientists at NASA. And to try to unravel its secrets close to Hell, the US Space Agency has planned to send two missions by 2028. We explain to you.
In Roman mythology, it refers to love, beauty and seduction. But for scientists and more particularly for NASA agents, it is mysterious although it closely resembles Earth. On June 2, the US Space Agency announced that it had selected two missions to Venus selected part of the Discovery program. A project that will be around $ 500 million.
The names of the two missions are evocative. The first one, Davinci+, suggests a tribute to the discoveries on the science of the human body made by Leonardo Da Vinci. It will be launched in order to understand the formation of Venus, its evolution, but also to know if an ocean has already formed.
For it, “a descent sphere will plunge through the planet’s thick atmosphere, making precise measurements of rare gases and other elements”Detailed NASA. With its 462 ° C on average, it far exceeds the temperatures of other planets in the solar system.
The second, Veritas, will allow scientists to know every nook and cranny of Venus. Indeed, it will aim to map the surface of the planet, located 41 million kilometers from Earth. But that’s not all since 3D reconstructions will be possible thanks to a synthetic aperture radar.
A system for “confirm whether processes such as plate tectonics and volcanism are still active on Venus”Can be read on the NASA website.
Two missions sent by 2028-2030 which are synonymous for NASA’s reconquest. It had been more than 30 years since no mission had intended theEvening Star. “It’s amazing how little we know about Venus, but the combined results of these missions will tell us about the planet from the clouds in its sky to volcanoes on its surface to its core.“said Tom Wagner, Discovery Scientist at NASA.
“It will be as if we have rediscovered the planet“he concluded.
