Q & A

What is the main challenge that NASA faces regarding the Redstone rocket in the script?

The main challenge is that the Redstone rocket can handle suborbital flight but is not capable of supporting orbital flight due to its inability to carry the weight of the capsule and push it into space.

How does Katherine Goble contribute to solving the problem with the Redstone rocket?

Katherine Goble uses her mathematical skills to analyze the available data and uncover the limitations of the Redstone rocket. She points out that while the rocket is fine for suborbital flight, it is not sufficient for orbital flight, highlighting the need for better calculations to understand the rocket's failure.

What mathematical concept does Katherine Goble apply to calculate the re-entry point for the capsule?

Katherine uses advanced mathematics, including concepts like distance-to-velocity squared and gravity, to calculate the exact re-entry point for the capsule. She also uses her knowledge of analytic geometry and numerical methods like Euler's method to solve the problem.

Why is the re-entry point calculation so critical for the mission?

The re-entry point is crucial because it determines the precise location where the capsule must re-enter Earth's atmosphere. If this point is wrong, the capsule could either burn up upon re-entry or be pushed out of Earth's gravity, which would be catastrophic for the astronauts aboard.

How does the script demonstrate the importance of teamwork and collaboration in solving complex problems?

The script emphasizes teamwork through the collaborative efforts of the NASA team, particularly between Katherine, Paul, and the other engineers. Despite the individual challenges and expertise, the success of the mission relies on their ability to work together, share knowledge, and trust each other's capabilities.

What role does the IBM 7090 Data Processing System play in the mission?

The IBM 7090 Data Processing System is used to perform calculations that are crucial for the mission, such as determining the launch, re-entry, and landing parameters. It helps process vast amounts of data at high speed, making it an essential tool for solving complex mathematical problems.

What does Paul emphasize regarding the need for Katherine’s mathematical skills in the script?

Paul emphasizes that Katherine's ability to perform advanced calculations is vital to the success of the mission. He recognizes her unique skills in handling difficult mathematical concepts, which have the potential to solve problems that others cannot.

Why is Katherine's ability to think beyond theoretical math important for the mission?

Katherine's ability to think beyond theoretical math is important because it allows her to approach problems in a practical, real-world way. Instead of relying on abstract theories, she applies numerical methods to solve critical challenges like the re-entry calculations, which require precision and accuracy.

What is the significance of Katherine calculating the exact re-entry coordinates for Colonel Glenn?

Katherine’s calculation of the re-entry coordinates is pivotal because it directly influences the safety of the mission. By determining the exact landing zone, she ensures that the astronauts have the best chance of a safe return, demonstrating her critical role in the mission's success.

What does the phrase 'math is always dependable' convey about Katherine's approach to problem-solving?

The phrase 'math is always dependable' reflects Katherine's unwavering confidence in the reliability of mathematics to solve real-world problems. Her belief in the consistency of math is what drives her to find solutions to complex challenges, even when others doubt or struggle with them.
