Introduction to Bravery in Space Exploration

When we talk about bravery in the realm of space exploration, one name often comes to mind: John Glenn. His historic flight was a testament to human courage and determination. But how would you rate John Glenn's bravery on a scale from 1 to 10? This article will explore the courage exhibited by Glenn and other pioneers in space exploration, while providing an in-depth analysis of the risks they undertook.

John Glenn and his Flight

When discussing John Glenn, the question of his bravery in taking that historic ride becomes central. Glenn’s flight on February 20, 1962, as the first American to orbit the Earth on Atlas missile, marked a significant milestone in the history of space exploration. The ride wasn't wholly voluntary; rather, it was driven by a combination of personal and national pride, not fear.

While Glenn’s courage cannot be understated, it’s also fair to consider the risks he faced. According to those involved in the Atlas rocket engine testing, the Atlas had notable issues like combustion instability. However, Glenn opted to fly with the engines available, emphasizing that the chance to be the first American in space was a greater impetus.

According to the story, Glenn didn’t wait for the improvements in combustion instability, even though an improved design was in the pipeline. He chose to take the risks with the best available equipment. This decision signifies an unerring sense of commitment and a willingness to face the unknown.

Other Heroes in Space Exploration

At the same time, the space race was a competition where many astronauts exhibited similar levels of courage. Astronauts like Gordon Cooper, Walter Schirra, and Alan Shepard also rode on Atlas rockets, acknowledging the shared risks of this endeavor.

Some astronauts took more calculated risks. For example, Valery Komarov, who is often described as the definitive 10/10 brave astronaut. Komarov’s bravery in the face of potential failure underscores the importance of opting for the highest level of risk acceptance.

Other notable moments include NASA’s STS-1 mission, which saw astronauts Deke Slayton and John Young. Their mission, which almost led to their demise, also required immense bravery and trust in the technology and their own judgment.

The Role of Human Computers and the Central Systems

Although spaceflight is often seen as a technological feat, the role of human computers, like Katherine Johnson, cannot be overstated. Johnson’s human calculations and her role in verifying the flight paths were pivotal. Her clearance of the numbers for Glenn’s flight was a remarkable example of how human ingenuity and courage played a significant part in space exploration.

One intriguing story involves Johnson’s input. Glenn famously inquired if she had reviewed the numbers, and upon receiving a positive confirmation, declared, “Then I’m good to go!” This anecdote highlights the reliance on human verification in such critical missions and emphasizes the collaborative effort behind space exploration.

The Hurdles and Challenges

The missions of these early astronauts were fraught with technical and procedural risks. The STS-1 involved complex systems with no previous test flights, and the Space Shuttle Solid Rocket Boosters (SRBs) had never been tested upright. The SRBs posed significant risks due to the sound overpressure and intense environment, nearly leading to the astronauts' uncontrolled descent.

Young himself mentioned that if he had known the extent of the risk, he would have ejected during launch. Crippen, another astronaut involved, did not believe in the survivability of ejection. The intense risks and potential consequences underscore the bravery and resilience of these pioneers.

Conclusion: Reflecting on Bravery in Space

In conclusion, the bravery of John Glenn and others in space exploration cannot be quantified on a single scale. Each mission tested the limits of human courage and technological prowess. The risks faced by these astronauts were not only technical but also emotional and psychological. Their determination to push the boundaries of human achievement, even in the face of danger, is a testament to the indomitable spirit of space exploration.
