It because of the tremendous force they COULD face if taken off vertically? Is this is due to inertia (resistance to change motion)?

Oh I see, thanks!davenn said:Hi Rohan
welcome to PF
The g-forces are the same on the person in either way
But when they are lying as they do, the forces are more evenly spread across the whole bodyDave

There are several reasons for placing astronauts horizontally during takeoff. First, it helps to evenly distribute the force of gravity on the body, reducing the strain on the cardiovascular system. Additionally, it also helps to prevent blood from pooling in the legs and feet, which can cause dizziness and other discomforts. Finally, it allows for easier access to the spacecraft in case of emergency.
No, laying horizontally does not have any significant impact on the launch trajectory. The direction of the spacecraft is determined by the angle of the launch pad, not the orientation of the astronauts inside. The spacecraft is also designed to adjust its trajectory during flight, so the astronauts' position does not affect the overall launch path.
There are minimal risks associated with astronauts laying horizontally during takeoff. The main concern is the potential for motion sickness due to the sudden acceleration. However, astronauts undergo rigorous training to prepare their bodies for the physical demands of launch. Additionally, spacecraft are equipped with medical supplies and protocols in case of any medical emergencies.
Technically, astronauts could sit upright during takeoff, but it is not the most efficient or comfortable position. Laying horizontally allows for a more even distribution of forces and reduces the strain on the body. It also helps to protect the astronauts in case of emergency, as they are securely strapped into their seats.
No, the position of the spacecraft during takeoff does not affect the landing. The spacecraft is designed to adjust its trajectory during flight and re-enter the Earth's atmosphere at a specific angle for a safe landing. The astronauts' position during takeoff has no impact on this process.
