The Apollo program is widely known for its groundbreaking accomplishments, including the historic landing of Apollo 11 on the moon in 1969. However, not all planned Apollo missions took place. Apollo 18, 19, and 20 are often referred to as the “Forgotten Apollo Missions,” as they were canceled due to budget constraints and other factors. In this article, we will explore the lost opportunities of these missions and their impact on future lunar exploration.

The Apollo Program: A Brief Overview

The Apollo missions

The Apollo program, carried out by NASA between 1961 and 1972, aimed to land humans on the moon and bring them safely back to Earth. There were a total of 17 Apollo missions, six of which successfully landed astronauts on the moon.

The objectives

The primary objectives of the Apollo program were to demonstrate American superiority in space, conduct scientific research, and explore the lunar surface.

The Canceled Apollo Missions: 18, 19, and 20

After the Apollo program, two entire Saturn V rockets, SA-514 and SA-515, remained unused, along with the third stage of SA-513. Initially intended for the Apollo 18 mission, SA-513 was repurposed (sans its third stage) to launch Skylab.

Reasons for cancellation

The three canceled missions were initially part of NASA’s plans but were ultimately canceled due to budget constraints, schedule conflicts, and the desire to shift focus to the development of the Space Shuttle program.

Budget constraints

The cost of the Apollo program was a significant factor in the cancellation of the later missions. As the program progressed, funding became increasingly scarce, leading to the decision to cancel Apollo 18, 19, and 20.

Mission	Planned Objective	Crew Members
Apollo 18	Explore Copernicus crater	Commander Richard F. Gordon, Command Module Pilot Vance D. Brand, Lunar Module Pilot Harrison H. Schmitt
Apollo 19	Explore Hadley Rille	Commander Fred Haise, Command Module Pilot William R. Pogue, Lunar Module Pilot Gerald P. Carr
Apollo 20	Explore Malapert Mountain	Commander John W. Young, Command Module Pilot Ken Mattingly, Lunar Module Pilot Charles Duke

The Planned Apollo 18 Mission

Objective

Apollo 18 was initially scheduled for launch in 1972, with the primary objective of exploring the lunar surface and conducting experiments in a region called the Copernicus crater.

Crew

The planned crew for Apollo 18 consisted of Commander Richard F. Gordon, Command Module Pilot Vance D. Brand, and Lunar Module Pilot Harrison H. Schmitt.

The Planned Apollo 19 Mission

Objective

Apollo 19 was slated for launch in 1973, with the primary goal of exploring the Hadley Rille, a geological feature on the moon formed by ancient volcanic activity.

Crew

The crew for Apollo 19 included Commander Fred Haise, Command Module Pilot William R. Pogue, and Lunar Module Pilot Gerald P. Carr.

The Planned Apollo 20 Mission

Objective

Apollo 20 was scheduled for launch in 1974, aiming to explore the moon’s southern polar region, specifically the Malapert Mountain, a unique geological feature.

Crew

The planned crew for Apollo 20 consisted of Commander John W. Young, Command Module Pilot Ken Mattingly, and Lunar Module Pilot Charles Duke.

The Lost Opportunities: Scientific and Exploration Goals

The cancellation of Apollo 18, 19, and 20 meant the loss of valuable opportunities for scientific research and exploration. These missions would have provided further insight into the moon’s geology, history, and potential resources. Additionally, they could have paved the way for more advanced lunar missions, including potential lunar bases and long-term human presence on the moon.

The Legacy of the Canceled Missions

Despite their cancellation, the Apollo 18, 19, and 20 missions contributed to the advancement of space exploration by inspiring future missions and generating public interest in space travel. Their legacy is felt in today’s lunar exploration programs, including NASA’s Artemis program, which aims to return humans to the moon by 2024.

The Impact on Future Lunar Missions

The canceled Apollo missions underscored the importance of sustainable funding and long-term planning for space exploration programs. Their cancellation influenced the direction of future lunar missions and provided valuable lessons for planning and executing ambitious space exploration projects.

Conspiracy Theories Surrounding Apollo 18, 19, and 20

In the years following the cancellation of the Apollo 18, 19, and 20 missions, various conspiracy theories emerged, claiming that these missions did occur but were covered up by NASA and the US government. Some theories suggest that these missions discovered evidence of extraterrestrial life or ancient artifacts on the moon.

Dispelling the Myths

There is no credible evidence to support conspiracy theorists’ claims about the Apollo 18, 19, and 20 missions. These theories are based on misinformation and a misunderstanding of the reasons behind their cancellation.

Lessons Learned from the Apollo Program

The Apollo program, including the canceled Apollo 18, 19, and 20 missions, taught us valuable lessons about the importance of long-term planning, sustainable funding, and international collaboration in space exploration. These lessons continue to inform current and future space missions.

The New Era of Lunar Exploration

The cancellation of the Apollo 18, 19, and 20 missions marked the end of an era in lunar exploration. However, the desire to explore the moon has not waned. Current projects, such as NASA’s Artemis program and international collaboration efforts, seek to return humans to the moon and establish a sustainable human presence on the lunar surface.

Conclusion

While the Apollo 18, 19, and 20 missions never materialized, their cancellation provided valuable insights into the challenges of space exploration. As we continue to push the boundaries of human knowledge and capabilities, the lessons learned from these forgotten missions will remain crucial in shaping the future of lunar exploration.
