On July 31, 1971, the United States launched the Apollo 15 mission, which became one of the most scientifically significant missions in the Apollo program. The mission was crewed by Commander David Scott, Lunar Module Pilot James Irwin, and Command Module Pilot Alfred Worden.
One of the mission's main objectives was to explore the lunar surface more extensively than previous missions. The astronauts spent three days on the Moon, conducting scientific experiments and collecting samples. They used the first lunar roving vehicle (LRV), which allowed them to travel much farther from the lunar module than ever before.
During their time on the Moon, Scott and Irwin discovered the famous "Genesis Rock," a large, white anorthosite rock that was believed to be part of the Moon's primordial crust. This rock provided crucial insights into the early history and formation of the Moon.
Another significant event occurred when Alfred Worden performed the first deep space EVA (extravehicular activity) on the return journey to Earth. He ventured outside the command module to retrieve film cassettes from the scientific instrument module bay, a compartment that housed various cameras and sensors used during the mission. This spacewalk, conducted nearly 200,000 miles (320,000 kilometers) from Earth, set a record for the farthest distance from Earth an EVA had ever been performed.
The Apollo 15 mission also left a lasting cultural impact on the Moon. The astronauts left behind a small aluminum sculpture called "Fallen Astronaut" to honor all the astronauts and cosmonauts who had lost their lives in the pursuit of space exploration. This sculpture, along with a plaque bearing the names of 14 deceased space explorers, remains on the lunar surface to this day.
In summary, July 31 marks the anniversary of the launch of Apollo 15, a groundbreaking mission that expanded our understanding of the Moon, set new records in space exploration, and left a powerful symbolic tribute on the lunar surface.
