The question of how many missions to the moon have there been requires a nuanced answer, separating the iconic human landings from the broader spectrum of robotic exploration. While the total number varies depending on whether one counts only successful landings, impactors, orbiters, or includes failed attempts, the history of lunar exploration spans more than six decades and involves dozens of distinct missions. This journey reflects the evolution of technology, from the first rudimentary flybys to the sophisticated sample-return campaigns of recent years.
Defining a Lunar Mission
To accurately count lunar missions, one must first define what qualifies. A mission is generally considered any spacecraft launched with the intent to reach the Moon, whether it enters orbit, lands on the surface, performs a flyby, or impacts the crater. This encompasses government programs like NASA's Apollo, the Soviet Luna series, and modern commercial initiatives. It also includes missions from emerging space nations and collaborative international efforts, painting a comprehensive picture of humanity's persistent fascination with Earth's natural satellite.
The Era of Early Exploration
The initial wave of lunar missions occurred in the 1950s and 1960s, primarily driven by the Space Race between the United States and the Soviet Union. During this period, the Soviet Union launched the Luna program, which included the first impactor (Luna 2), the first photos of the far side (Luna 3), and the first soft landing (Luna 9). Concurrently, the United States conducted the Ranger, Surveyor, and Lunar Orbiter programs to gather critical data for the upcoming human landings, significantly increasing the total count of missions to the moon during this intense decade.
The Human Landings
Apollo Program
When people ask how many missions to the moon there have been, they are often thinking of the Apollo program, which represents the pinnacle of 20th-century space exploration. Between 1968 and 1972, NASA successfully landed twelve astronauts on the lunar surface across six dedicated landing missions: Apollo 11, 12, 14, 15, 16, and 17. Each of these missions included an orbiter component, and when combined with the command module tests of Apollo 8 and 10, the Apollo program alone contributes significantly to the total number of manned lunar flights.
The Robotic Scientific Missions Following the Apollo era, the focus shifted to long-term scientific study through orbiters, rovers, and sample returns. The Soviet Union continued its Luna series with sample-return missions like Luna 15, 20, and 24, which brought lunar rocks back to Earth. The United States sent the Lunar Orbiter series, the sophisticated Clementine and Lunar Prospector orbiters, and the Lunar Reconnaissance Orbiter, which remains operational today. Internationally, missions from Japan (Hiten and Kaguya), the European Space Agency (SMART-1), India (Chandrayaan-1), and China (Chang'e series) have vastly expanded our understanding of the moon.

In the 21st century, lunar exploration has diversified to include private companies and new national space agencies. NASA's Artemis program aims to return humans to the moon, while commercial landers from companies like SpaceX and various international partners are becoming a reality. Missions from China, including the Chang'e 4 far side landing and the Chang'e 5 sample return, demonstrate continued innovation. As nations plan future lunar bases and research stations, the count of missions continues to climb, marking a new chapter in lunar exploration.
