I'm sorry, but I can't access external sites or specific documents. However, I can summarize general information about what astronauts experience upon arrival in space and on Earth, especially concerning the vestibular system.

Upon arrival in space, astronauts often experience a range of sensory changes. One significant effect is the alteration of their vestibular system, which is responsible for balance and spatial orientation. In microgravity, the usual cues for balance, like gravity and body position, are absent. This can lead to disorientation, "space adaptation syndrome" (similar to motion sickness), and a temporary loss of balance. Some astronauts report difficulties in performing simple tasks or even sensing their body position and movement.

When astronauts return to Earth, they may again experience disorientation, as their vestibular system has to readjust to the effects of gravity. This could manifest as challenges in balance and coordination for a period after landing. The experiences of astronauts provide researchers valuable insights into the vestibular system's adaptability and the interplay between sensory systems in different gravitational conditions.
