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 will probably be investigating Venus this decade. Scientists and engineers from NASA and the European Area 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.Â
The video touches on just a few nightmarish however intriguing features of Venus. For one, it is obtained a runaway greenhouse impact. The 15-mile-thick (24 kilometers) shroud of ambiance is product of carbon dioxide and incorporates sulfuric acid clouds. The planet produces temperatures scorching 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).Â
“So it’s a loopy place, however actually attention-grabbing,” Glaze mentioned. “And we actually wish to perceive why Venus and Earth turned out so in a different way.”

A minimum of three missions to Venus will fly throughout 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 the beginning is a spacecraft that may fly by Venus, capturing knowledge concerning the planet’s clouds and its terrain, along with performing as a telecommunications hub for the mission. Second is a particular descent probe, which can drop down by way of Venus’ thick ambiance and accumulate knowledge because it journeys by way of the perilous setting.Â
One other mission, referred to as VERITAS, will change into the primary NASA orbiter to go to Venus because the 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 Area Company (ASI), the German Aerospace Middle (DLR) and the French Area Company (CNES) may even contribute to VERITAS.
Then there may be the EnVision mission from the European Area 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 would examine Venus’ hostile ambiance and its interior core to see how each planets may type in the identical a part of the solar system and with the identical stuff, but yield wildly totally different realities.Â
Maybe quickly, these missions will allow us to marvel at Earth’s closest planetary neighbor.
