A project launching in 2029 to examine this body is led by PI and Goddard Space (-5[1])Flight Center chief scientist James Garvin and is named for Leonardo da Vinci. Circular rims are characteristic of craters on this body (-5[1])whose youthful nature is attributed to either a “steady-state” or “catastrophic” resurfacing event. A 2017 Nature Geoscience (-5[1])paper (15[1])compared (-5[1])simulations of plume-induced subduction to semicircular ridges (-5[1])seen on (15[1])this body near (15[3])a site (10[2])named (15[1])for (10[1]-5[1])Quetzalpetlatl. (*) Alpha (10[1]-5[1])Regio is located on (10[1])this body, which features (10[2])heavily (10[1])deformed (10[1])“tesserae” and pancake (10[2])domes (10[1])that were first photographed (10[1])by a (10[1])series of Soviet probes. (10[1])The Magellan Probe (10[2]-5[1])studied this body, where major continents like Aphrodite and Ishtar Terras (10[1])are located. (10[1])For (10[1])10 (10[1])points, an (10[1])atmosphere with clouds (10[1])of concentrated sulfuric acid rests above what planet with an orbit lying between Mercury and Earth? (10[1])■END■ (10[4])
