Summary
Wilson, a seasoned geologist, recounts his leadership of a lunar expedition two decades ago to the grand Mare Crisium, ominously known as the Sea of Crisis. Despite its foreboding name, the mission initially seems routine and unremarkable. Wilson goes so far as to lament the lack of peril and excitement in their lunar endeavors, describing them as mundane and predictable.
Equipped for Exploration
The expedition, led by Wilson, is thoroughly prepared for its journey. They travel from a lunar base located 500 miles away, burdened with a range of heavy equipment, including overland tractors, rockets, and tools for scientific sampling. This extensive preparation leaves them seemingly untroubled by the mysteries of the lunar environment. With constant radio communication with their base and the ability to survive for up to a month in their pressurized tractor cabins, the crew is well-prepared for any emergencies that may arise.
Comfort and Discovery
The crew experiences a comfortable stay on the moon, complete with shortwave radio signals transmitting music from Earth, making their meals of freshly cooked food more enjoyable. However, this expedition soon veers off its expected course. During a morning breakfast preparation, Wilson notices a metallic glint on a distant mountain at the plateau's edge. Despite his team's unanimous disagreement, Wilson and his assistant, Garnett, decide to investigate the object further.
Astonishing Find
Upon reaching a mountain towering ten thousand feet at the plateau's boundary, Wilson uncovers a small crystalline pyramid. At first, he speculates it might be the creation of an extinct, previously unknown, native civilization. Yet, the lack of any additional artifacts and the existence of a sophisticated force-field surrounding the structure quickly convince him that this artifact is not of lunar origin nor from Earth.
The Quest to Understand
Wilson details the two-decade-long scientific effort to understand and dismantle the artifact. However, all conventional methods fail. Finally, scientists resort to atomic means, demolishing the inscrutable artifact along with its enigmatic energy source. Its purpose remains a mystery, as a relic that withstood natural forces for millennia is rendered inoperative by human hands.
Interpretation and Implications
Wilson offers his interpretation of the artifact's significance. He believes it to be a sentinel, part of an extensive network placed throughout the universe by a vastly advanced civilization to monitor the emergence of life. According to Wilson, the destruction of the sentinel serves as a signal to its creators that intelligent life has evolved from Earth's primordial beginnings and has demonstrated its capability by leaving its home planet. This event likely heralds the arrival of extraterrestrial contact, as humanity's actions have surely drawn attention to its presence in the cosmos.
