However, despite numerous attempts, many launches failed to make it past Earth orbit or crashed into the lunar surface. The program faced numerous setbacks, including delays in landing due to difficulties in analyzing the lunar surface.

However, Luna 15 entered lunar orbit ahead of Apollo 11 but crashed into a mountainside just hours before Apollo 11 was set to lift off. The Soviets kept details of the mission secret from the United States, leading to confusion and speculation.

Despite its failure, Luna 15 paved the way for future missions in the Luna program, such as Luna 16 which successfully landed on the Moon and returned samples to Earth through robotic probes. The Luna program continued to achieve milestones in lunar exploration and sent a rover to
