Venera 10 launched 6 days after V9 (14 June '75) and landed 3 days after its sibling (25 October). This map shows the area. Like Venera 9 it was east of Beta Regio, but 1500 km further south. As with all landers so far the target was essentially unknown, only seen in very low resolution radar reflectivity images from Earth. Here we see a landscape of bright (rough) and dark (smoother) features, which we will see closer tomorrow.

Venera 10 landed in the area shown here at two scales - at left a map spanning 500 km shows major landforms, at right, full Magellan resolution gives us details of part of the landing ellipse. We see mixed geology - the dark areas are smooth (ish) plains, probably sediments blown around by the wind. What makes sediment on Venus? Impacts, chemical weathering and maybe volcanic ash. A big bright area (Hyndla Regio) is an upland cut by many faults.
