| Luna-21 entered lunar orbit on January 12, 1973, and landed on January 15. The robotic rover, Lunokhod-2, rolled off the landing platform to explore the Moon's surface for approximately four months. Similar to Lunokhod-1, it was equipped with two vidicon television cameras for navigation control and four optical-mechanical cycloramic cameras. The rover returned 86 panoramas and more than 80,000 navigational video images. |
