Three impact craters on Venus seen with Magellan spacecraft radar.

In northwestern Lavinia Planitia, Howe crater is 37 kilometers (23 miles) in diameter in the lower portion of the image. The others are Danilova, above it and to the left, and Aglaonice, right of Danilova.

This video on the Magellan Spacecraft Mission shows the launch of the mission and how it uses radar to map under the clouds.
