Vishniac is the larger crater of the Martian surface feature called the Giant's Footprint. It was named after Wolf V. Vishniac, a microbiologist who died on an expedition to Antarctica. Fittingly, the crater lies in the Antarctic of Mars.[1] The feature was originally observed by Mariner 7 in 1969. In 1999, the Mars Global Surveyor's Mars Orbiter Camera was able to provide more detailed pictures.[2] The crater measures approximately 80 kilometers in diameter. Its name was approved by the International Astronomical Union in 1976.[3]
