In 1990, a former Soviet space expert named T. Posov announced a shocking revelation in Moscow: a Soviet unmanned spacecraft had captured an unusual warning message on Mars, written in English and reading 'Leave.' This message measures approximately half a mile long and 75 meters wide, seemingly carved into a giant rock by Martians. Posov speculated that this might be a sign of Martian discontent regarding Earth's excessive exploration of Mars, urging humans to cease their activities.
Posov revealed that shortly after the spacecraft transmitted the photos, it mysteriously disappeared. Whether it was destroyed by Martians or captured remains an unsolved mystery. He suggested that establishing contact with Martians could potentially resolve this issue. This announcement immediately garnered widespread attention from the Western scientific community, with many believing it to be a significant discovery.
