In 1970, Lunokhod 1 drove 10 km across the Moon before contact ended in 1971; in 2010, LRO found it, and its reflector gave a signal four times Lunokhod 2’s

After decades of disappearance, the Soviet rover Lunokhod 1 was found anew by NASA's Lunar Reconnaissance Orbiter. In 2010, physicists utilized laser pulses to pinpoint its reflector, sparking fresh interest in studying the Moon's core. This event not only underscores the importance of meticulous data management but also serves as a dire reminder for future lunar explorations and the collaboration between space agencies.
