The Criteria for Selection
Criteria for Selection of Apollo Astronauts
For the selection of astronauts intended for the Apollo missions, a detailed selection procedure was followed by NASA. This procedure focused on both the professional and personal qualifications of candidates. These qualifications were not simplistic; rather, they were a set of comprehensive requirements, which included physical fitness, intellectual capacity, aptitude for learning, technical skills, and the ability to cope under extreme conditions.
Astronaut candidates, also known as “ASCANs”, were required to have a bachelor’s degree in engineering, biological science, physical science, or mathematics. Furthermore, an ASCAN should have at least 1,000 hours of flying time in jet aircraft. The age limit, although not rigid, typically favored those under 34 years of age. Good eyesight was mandatory, with uncorrected vision of 20/50 or better in each eye and corrected to 20/20. The candidate’s blood pressure, when seated, should not cross a certain threshold.
Professional competence was one of the significant criteria. The ability to fix, maintain, and troubleshoot essentials like life support systems, communications systems, and scientific equipment on board was required. NASA also sought individuals with a high degree of stamina and stress resistance, along with the ability to pilot the spacecraft under challenging and life-threatening situations.
Training and Preparation for Apollo Astronauts
Once the astronaut candidates were selected, they had to undergo an extensive training regimen to equip them to withstand the rigors of space travel. The training involved various simulations to mimic the conditions and challenges an astronaut might face during the Apollo missions.
They underwent classroom training on spacecraft systems, navigation, geology, and experiment handling. Zero gravity flights were done in a specially modified aircraft dubbed the “vomit comet” to give the astronauts a chance to experience and familiarize themselves with the disorienting effects of microgravity. Underwater training was another essential part of the program to simulate the conditions of weightlessness and the maneuverability of the spacesuit in a zero-gravity environment.
Apart from the technical training, the candidates also received survival training since there was a chance that they might land in a remote or hostile area on Earth upon return. This included water, desert, and jungle survival training.
The Unflown Astronauts of the Apollo Program
Regardless of the arduous screening requirements and intense training involved, not every astronaut who trained for the program made it into space. A selection found themselves unable to participate in an Apollo mission, due to a mixture of circumstances. Some were moved to other programs, others chose to depart NASA, a handful were medically disqualified, and a number met a premature end during training or unrelated accidents.
However, we mustn’t undervalue the significant contributions these astronauts made to both the Apollo program and the broader sphere of space exploration. Their commitment, self-sacrifice, and rigorous training provided a foundation of knowledge that significantly contributed to the success of the Apollo missions, as well as the progression of future manned space expeditions.
Key Figures Unflown
The Unfulfilled Voyage of Astronaut Clifton Williams
Among the astronauts who didn’t get to fly in an Apollo mission was Clifton C. Williams. He was part of NASA’s Group 3, served as the backup pilot for Gemini 10, but unfortunately, his life was cut short by a plane crash in 1967. Williams was slated to serve as the Lunar Module Pilot for Apollo 12, a mission that he never had the opportunity to embark on. Despite his untimely death and not featuring in any manned mission, Williams still holds an important place in the annals of NASA’s early astronaut cohort. His precision and diligence during the Gemini and Apollo program training periods left an enduring influence.
Joseph Kerwin: The Skylab Astronaut
Joseph P. Kerwin, who was initially assigned to the Apollo program, never participated in an Apollo flight. However, his contribution to space science is exceptional. Kerwin was part of NASA’s Group 4 and scheduled to fly as a science pilot in the Apollo 15 mission. When the group’s original concept changed from a standalone mission model to a Skylab program, Kerwin’s path to becoming an Apollo astronaut was deterred. Instead, his role shifted, and he became America’s first physician in space as part of the Skylab 2 mission in 1973. His in-depth research and reports from this mission subject established vital data on human health and performance in a space environment.
Edward Gibson: The Scientist-Astronaut Who Never Flew Apollo
Edward G. Gibson was another astronaut who, despite not flying in the Apollo missions, profoundly impacted the direction of NASA’s space exploration. He was a scientist with a Ph.D. in Engineering and was a part of NASA’s Group 4. Gibson was initially trained for a mission that would land him on the moon, but the Apollo Applications Program shifted focus from lunar exploration to studying Earth’s magnetic field. Gibson then flew the Skylab 4 mission and conducted experiments that increased understanding about long-duration space flight, the sun, and Earth’s resources.
Donn F. Eisele: Apollo 7 and Beyond
Although Donn F. Eisele flew in the Apollo 7 mission, he did not get a chance to take part in any subsequent flights. This was due to NASA’s rotation system, where he was next in line for Apollo 10, a low-Earth orbital test, not a moon mission. His chances for a moon mission evaporated when deemed medically unfit for spaceflight following a shoulder surgery. Later, Eisele served as the backup command module pilot for Apollo 10 and then worked on the Apollo Applications Program, which later became the famous Skylab program.
Despite never having a chance to participate in an Apollo mission, each of these astronauts made significant contributions towards NASA’s space programs. Their dedication and determination had a profound impact on advancing our understanding of space, leading to the success of future missions.
Interpersonal Dynamics within Apollo
Understanding the Apollo Program Dynamics
NASA’s Apollo program, operative from 1961 to 1972, was a monumental project with vast implications for space exploration and for those involved. The program’s primary aim was executing a human landing on the moon and successfully returning the crew. However, not every astronaut selected for the Apollo program experienced space travel. This circumstance created a unique web of interpersonal dynamics amongst the Apollo astronauts. These complexities existed between those who touched the stars and those who kept the mission running from the ground.
Selection and Training Process
Steps towards being part of the Apollo missions were highly fierce and competitive. After a rigorous selection and training process, some astronauts were destined never to leave the Earth’s surface, serving as backup crew members and providing ground support. This scenario often brought forth challenges at a psychological level and impacted the collaboration between the astronauts themselves, as well as with their superiors and teams.

The identity of being a part of Apollo, yet never flying, created a unique mental burden.
Resilience Amidst Unfulfilled Expectations
Yet, many grounded Apollo astronauts demonstrated considerable resilience. By focusing on the collective goal of the Apollo missions and their personal contributions to space exploration – no matter how indirect – they found purpose and validation. According to several accounts, the grounded astronauts took pride in their roles, seized the opportunity to learn and develop, and redefined their own measures of success.
Interactions between Flew and Grounded Astronauts
Exploring the camaraderie between the astronauts who flew and those who didn’t reveals another layer of complexity. The mutual respect and understanding that stemmed from shared rigorous training and common goals often blurred the lines between them. Although there was a dichotomy in their experiences – the thrill of spaceflight versus the grounded reality – this shared identity and mutual respect that developed helped foster a strong, cohesive group dynamic.
Brief Account of Grounded Astronauts
Some of the astronauts who never flew on Apollo missions included astronauts like Donn Eisele, who was grounded following his flight as part of the Apollo 7 mission due to personal issues, and Ken Mattingly, infamously grounded just days before the Apollo 13 mission when he was exposed to German measles. Linked to each of these stories are narratives of resilience, adaptation, and unyielding team spirit.
Conclusion
A comprehensive analysis of the Apollo program highlights its human element, wherein valor, teamwork, and resilience sparkled as brightly as the ventures into the uncharted cosmos.
