   First Human Steps on the Moon

   Neil Armstrong and Buzz Aldrin become the first humans to walk on the Moon during Apollo 11, just days after the Soviet lunar landing. The event is widely covered in the U.S. and globally, though Soviet media downplays it, emphasizing their earlier achievement. The two nations continue to present their successes as separate milestones in the space race.

   DIVERGENCE: N1 launch succeeds — Leonov lands on the Moon

   The second N1 launch on July 3, 1969 succeeds instead of exploding. The USSR mounts a crash crewed mission: Alexei Leonov lands on the Moon in the L3 lander in early July 1969, weeks before Apollo 11's scheduled July 16 launch, and returns safely.
