Which significant achievement did the robotic Luna program accomplish regarding lunar exploration?
Answer
Transmitting the first images from the far side of the Moon
Although the crewed lunar mission failed, the concurrent, secretly funded robotic exploration efforts under the Luna program yielded significant scientific and technological victories for the Soviet Union. Among these notable successes were achieving the first soft landing on the Moon, the retrieval of lunar soil samples via automated craft, and perhaps most distinctively, capturing and transmitting the very first images originating from the far side of the Moon, areas never before seen by humanity.
