Explanation
About 50 years after the Apollo program, NASA's Artemis II spacecraft reached lunar orbit and became the first crewed mission to reach the far side of the Moon.
The far side of the Moon cannot be seen directly from Earth, and radio signals are blocked there, making relay satellites essential for operations. This flight is positioned as an important step toward future crewed lunar landings, a lunar base, and even exploration of Mars. Reaching the "far side" for the first time in half a century symbolizes an era in which space development is accelerating once again.
