A brand new NASA video makes the case that Venus is Earth’s “evil twin.”
The nefarious moniker is revealed to be, in a method, an apt description of why astronomers shall be investigating Venus this decade. Scientists and engineers from NASA and the European House Company are gearing as much as ship three new missions to the second rock from the sun. They wish to know a complete lot extra concerning the close by planet, which resembles Earth in so some ways, and but is so strikingly totally different.
The video touches on a couple of nightmarish however intriguing features of Venus. For one, it is received a runaway greenhouse impact. The 15-mile-thick (24 kilometers) shroud of environment is fabricated from carbon dioxide and accommodates sulfuric acid clouds. The planet produces temperatures sizzling sufficient to soften lead. Lori Glaze, NASA’s director of planetary science, mentioned within the video that the Venusian floor can attain 900 levels Fahrenheit (480 levels Celsius).
“So it’s a loopy place, however actually fascinating,” Glaze mentioned. “And we actually wish to perceive why Venus and Earth turned out so in another way.”

At the least three missions to Venus will fly inside the subsequent decade or so. There may be NASA’s DAVINCI, brief for Deep Environment Venus Investigation of Noble Gases, Chemistry and Imaging, which incorporates two main elements. At first is a spacecraft that may fly by Venus, capturing information concerning the planet’s clouds and its terrain, along with appearing as a telecommunications hub for the mission. Second is a particular descent probe, which can drop down by way of Venus’ thick environment and acquire information because it journeys by way of the perilous atmosphere.
One other mission, referred to as VERITAS, will change into the primary NASA orbiter to go to Venus for the reason that Nineteen Nineties. VERITAS is brief for Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy. The spacecraft will develop a big-picture have a look at Venus and its historical past, aiding scientists who wish to know extra about its volcanoes and to find out whether or not Venus ever had water. The Italian House Company (ASI), the German Aerospace Middle (DLR) and the French House Company (CNES) may also contribute to VERITAS.
Then there may be the EnVision mission from the European House Company (ESA). The NASA-supported mission targets a launch within the early 2030s. When it reaches Venus, EnVision will attempt to be taught why Venus turned Earth’s “evil twin,” because the NASA video describes it. Particularly, it should research Venus’ hostile environment and its interior core to see how each planets might kind in the identical a part of the solar system and with the identical stuff, but yield wildly totally different realities.
Maybe quickly, these missions will allow us to marvel at Earth’s closest planetary neighbor.
