Why are astronauts placed horizontally when taking off?

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

Hi Rohan
welcome to PF :smile:

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 body

The g-force you can stand depends on the direction of that force, and where the force goes through your back to front (or vice-versa) gives you the best ability to withstand it. Mary Roach's book Packing for Mars has a rather good section on this (the book is hilarious too).

I guess it's also easier on their spine?
