Features: So far, the most comprehensive and collectible illustrated archive of the first human moon landing. On every clear and starry night, sitting on the balcony, or under the faint and bright light of the waxing or waning moon, it always evokes a flood of thoughts and emotions—whether it's reflecting on the times, longing for the future, or reminiscing about past friends and memories. Perhaps no celestial body can evoke such rich and complex emotions as the moon. "The story of exploration is first and foremost the story of humanity!" — William Gatzman "I believe that our country should achieve the goal of sending a man to the moon and returning him safely to Earth before the end of this decade." — President John F. Kennedy's speech to Congress on May 25, 1961 "On July 1969, humans from Earth left their footprints on the moon, the first time in the solar system. We came here on a peaceful journey on behalf of all humanity." — A message inscribed on the metal plate left on the moon by Apollo 11 As they journeyed to distant planets, after completing the docking task, the three astronauts took off their spacesuits and put on comfortable flight suits to rest. Due to a malfunction in the ground receiving station, the originally planned first television broadcast was postponed until the station was repaired. On the large screens in the control center, people saw the beautiful Earth footage transmitted by the astronauts. Surrounding the Earth was a mysterious pale blue atmosphere, and the faint outlines of continents and oceans also sparked the imagination. The journey to the moon took three days, during which the astronauts had to endure the loneliness of the vast universe while also performing their tasks diligently. In the pitch-black vacuum of space, after detaching the lunar module from the third stage rocket, Apollo 11 reoriented itself and placed the lunar module on top of the command module, heading straight for the moon. Apollo 11 raced through the dark space, gradually slowing down. The spacecraft was flying between the Earth and the moon, influenced by the gravity of both. The Earth's gravity slowed the spacecraft, pulling it back, while the moon's gravity accelerated it toward the moon. Initially, when the spacecraft was closer to the Earth, the Earth's gravity was dominant, causing the spacecraft to slow down, while the moon's gravity was negligible. As the flight progressed, the Earth's gravity decreased, and the moon's gravity increased. At a certain point, the two forces balanced. As long as the spacecraft's speed did not drop to zero at this point, the moon's gravity would pull it closer, gradually increasing its speed. The velocity gained at launch was sufficient to prevent the spacecraft from stopping midway. On the lunar orbit, Apollo 11 began to rotate, spinning at a uniform rate of three times per hour in space, like roasting a kebab over a fire. If it didn't rotate, the side facing the sun would reach temperatures as high as 200 degrees Celsius, while the side away from the sun would drop to minus 150 degrees Celsius. This extreme temperature difference could cause the spacecraft's metal hull to deform. Therefore, the spacecraft slowly rotated around its longitudinal axis during flight, allowing it to evenly distribute the heat from the sun. After the television broadcast ended, the three astronauts began their first meal in space, which was also their first dinner. In space, food had to be as lightweight and compact as possible, easy to consume and nutritious, and free of crumbs, as astronauts were in a weightless state with limited space. The astronauts' food was packaged in plastic film within meal packs. Before launch, the command center had equipped each astronaut with enough food for five travel days and a small amount of snacks. After dinner, communication between the spacecraft and the ground command center was temporarily interrupted, and Collins, Aldrin, and Armstrong successively fell asleep. The planned sleep duration was nine hours. However, the ground command center continued to monitor everything on the spacecraft to prevent any unexpected incidents. Everything was proceeding as planned. July 17th. As the spacecraft approached the moon, the moon's gravity became stronger, affecting its flight trajectory. Under normal circumstances, a speed adjustment would suffice. However, if the trajectory deviation was too large, the spacecraft's direction would need to be changed using its rocket thrusters.
