Q & A
What is the primary function of the clamp arms during the rocket launch?
-The clamp arms are crucial in holding the rocket in place during launch preparations. They open up to allow the second stage of the rocket to recline, ensuring a safe launch.
What does the pressurization of Falcon 9 signify?
-The pressurization of Falcon 9 indicates that the rocket is being prepared for launch. It is a critical step that ensures the rocket is strong enough to stand on its own and can handle the forces exerted during liftoff.
What is the significance of the white clouds seen during the launch?
-The white clouds are a result of the super chilled liquid oxygen boiling off in the warmer air. This is a normal occurrence and indicates that the rocket is being filled with the necessary propellants for launch.
What does the term 'stage one locks load' refer to in the context of the rocket launch?
-The term 'stage one locks load' refers to the process of loading propellant into the first stage of the rocket. The completion of this process is a significant milestone leading up to launch.
What is the role of the Merlin vacuum engine in the Falcon 9 rocket?
-The Merlin vacuum engine is responsible for carrying the crew to orbit. It ignites after the first stage separates, providing the thrust needed to continue the journey into space.
Why is water poured onto the launch pad during a rocket launch?
-Water is used to absorb and dampen the loud sounds produced by the rocket during launch. These sounds can create loads that impact the rocket structure, so water helps to prevent potential damage from the rocket's intense noise.
What does the flight termination system being armed indicate?
-The flight termination system being armed means that the system is ready to destroy the rocket if necessary, should any critical failures occur during the launch. This is a safety measure to prevent uncontrolled flight and potential harm to the surrounding areas.
What is the purpose of the boost back burn in the first stage of Falcon 9?
-The boost back burn is a maneuver that slows down the first stage of the rocket as it returns to Earth. This is the first of two burns that prepare the stage for a controlled re-entry and landing.
What does the term 'nominal trajectory' mean in the context of the space mission?
-A 'nominal trajectory' refers to the expected or planned flight path of the spacecraft. When the guidance, navigation, and control officer announces a 'nominal trajectory', it means that the spacecraft is following its intended path without any deviations or issues.
What is the significance of the zero-g indicator brought by the crew on board?
-The zero-g indicator is a tradition carried out by astronauts to demonstrate the free-floating nature of objects in microgravity. It serves as a symbol of the transition from Earth's gravity to the weightlessness of space and is often a personal or symbolic item chosen by the crew.
What is the main objective of Project Eagle mentioned in the script?
-Project Eagle aims to investigate the impact of space microgravity on human heart micro-tissues generated from stem cells. The goal is to find ways to promote the maturation of these cells for potential use in cardiac regeneration on Earth.
