"During launch on a rocket with liquid engines ... the liftoff is very smooth, and one really can't feel it... "Ignition of the next stage engine(s) causes a momentary bump in G-force," he said. "As you get to the last part of ascent, you feel some G's come on through your chest, but it is not uncomfortable." When the spaceship's engines cut off, though, Chiao said you'd become "instantly weightless" as you temporarily coasted through space. "You feel like you are tumbling, as your balance system struggles to make sense of what is happening, and you are very dizzy,"... this can cause nausea.".. "As you start to re-enter the atmosphere, you would feel the G's come on smoothly and start to build," Chiao said. As the spaceship nosed up and down to shed speed, he added, you'd at points feel about 5 G's, which would make you feel roughly five times as heavy. As the spaceship sped toward the ground, its engines would fire to land it on a floating barge. "You would both feel and hear" the engines, Chiao said. "As the thrust builds, you would feel the G's come on again, and then at touchdown, you would feel a little bump."
