Why in News?<\/strong><\/h2>\n

A study published Thursday in the journal The Nature Astronomy<\/strong> suggests that Venus in its youth may have possessed a key Earth-like trait: plate tectonics<\/strong>, the continual reshaping of pieces of the planet\u2019s outer crust.<\/p>\n

What is the comparison between Earth and Venus ?<\/span><\/strong><\/h2>\n\n\n\n\n\n\n\n\n\n\n\n\n

What models were adopted in the study?<\/strong><\/h2>\n

(1) Tectonic models types- <\/strong>Scientists set up computer simulations exploring two types of tectonic models.
\n(A) The stagnant lid Model- <\/strong>It describes worlds like Mars and the Earth\u2019s moon where the\u00a0 \u00a0 \u00a0outer crust consists of a solid shell are unmoving.
\n(B) The<\/strong> plate tectonics Model- <\/strong>It models on the earth’s plate tectonics activities. On Earth, about 80 percent of volcanism occurs along mid-oceanic ridges where two tectonic plates are spreading apart and magma upwells.<\/p>\n

What are the key findings of the study ?<\/strong><\/h2>\n

(1) Less Nitrogen in Venus than what is estimated today-<\/strong> The simulations indicated that in Venus, there would be less nitrogen than what is observed today (current estimation of Nitrogen is 3.5%).<\/p>\n

(2) Simultaneous plate tectonic activities in both earth and Venus-<\/strong> Very likely, both the planets had plate tectonics operating roughly at the same period of time.<\/p>\n

What are upcoming missions to study about Venus?<\/strong><\/h2>\n

(1)NASA\u2019s Davinci spacecraft (Launch in 2029)<\/strong>-To make precise measurements of the gases in the atmosphere, providing clues to present-day volcanism.
\n(2) NASA mission (Veritas)<\/strong>– To make detailed measurements of the planet\u2019s gravity and take high-resolution images of the surface.
\n(3)The European Space Agency mission(EnVision)<\/strong>– To help scientists understand why conditions on Earth and Venus diverged so much.<\/p>\n
