NASA / JPL Markham Crater and Surroundings Markham Crater on Venus, as imaged via radar by the Magellan spacecraft. Markham is the round crater with the light-colored outflow at the upper right. Scientists interpret the feature as impact melt or fluidized ejecta created by meteorite impact. The crater is about 75km across.
Giant Ancient Impact Crater Confirmed in Iowa - 3-D perspective map of the Decorah impact feature looking northward. (Credit: USGS/Adam Kiel graphic/Northeast Iowa RC). A monster lurks under northeastern Iowa. That monster is in the form of a giant buried basin, the result of a meteorite impact in central North America over 470 million years ago.

These images are composites of the complete radar image collection obtained by the Magellan mission. The Magellan spacecraft was launched aboard space shuttle Atlantis in May 1989 and began mapping the surface of Venus in September 1990. The spacecraft continued to orbit Venus for four years, returning high-resolution images, altimetry, thermal emissions and gravity maps of 98 percent of the surface.
