Can astronauts actually feel the sensation of being in orbit, or is it more of an abstract concept that they understand intellectually but don't physically experience? Does the lack of gravity or the unique environment of space create any sensations that are unique to orbiting the Earth? And if so, how do these sensations compare to those experienced on Earth? Additionally, do these sensations change depending on the specific orbit or mission parameters? Understanding these nuances could provide valuable insights into the human experience in space and inform future space exploration efforts.
