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 whose youthful nature is attributed to either a “steady-state” or “catastrophic” resurfacing event. A 2017 Nature Geoscience paper compared simulations of plume-induced subduction to semicircular ridges seen on this body near a site named for Quetzalpetlatl. (*) Alpha Regio is located on this body, which features heavily deformed “tesserae” and pancake domes (10[1])that were first photographed (10[1])by a series of Soviet probes. The Magellan Probe studied this body, where major continents like Aphrodite and Ishtar Terras (10[1])are located. For 10 points, an atmosphere with clouds of concentrated sulfuric acid rests above what planet with an orbit lying between Mercury and Earth? (10[1])■END■
