If you mean by observation, pretty much since man could draw. There are detailed "maps" of star patterns in languages too old for us to read, and there are pre-Judeo-Christian models of the night sky. Moon gods are a common religious theme - pretty much forever.
If you mean physically, NASA's space program was initiated during Kennedy's administration in response to the Soviets. Why? We wanted to be there first, and technically we were (at least, on the moon.)
People were scared of Sputnik because it was the first artificial satellite launched by the Soviet Union in 1957, signaling their advancement in space technology. This event sparked fears of Soviet dominance in space and raised concerns about national security for the United States, leading to the start of the space race.
Sputnik was the name of the first artificial satellite launched into space by the Soviet Union in 1957. It marked the beginning of the space age and the start of the space race between the United States and the Soviet Union.
The space race began in 1957 when the Soviet Union launched the first artificial satellite, Sputnik 1. This event marked the start of a competition between the United States and the Soviet Union to achieve milestones in space exploration and technology.

The bidirectional A search algorithm improves efficiency by exploring the search space from both the start and goal nodes at the same time. This allows the algorithm to converge faster towards a solution by meeting in the middle, reducing the overall search space that needs to be explored.

Europeans created maps first so they will know where they are going when they were exploring North America.
