"On 18 January Lunokhod 2 was driven to a point on the north rim of the 25 m crater where it photographed the landing stage and the hill Le Monnier Alpha in the distance to the southwest. Here it was turned in place to create a circular mark with its wheels, and then moved a few meters where it made a second circle. The resulting figure 8 marking was later described as a memorial to commemorate International Women's Day, 8 March, which was a holiday in the Soviet Union and is in Russia today."
