Universe Today's Nancy Atkinson reports.
Here’s some footage from some the Aerospace Medical Research Laboratories which include a test of the effects of weightlessness on cats in a C-131 “vomit comet” that simulates weightlessness. Best I can tell, this research was done in 1947. Think of it in the same vein as all those weird tests the early astronauts had to endure.
The text from the video: “In these experiments you can see the disorientation resulting when an animal is suddenly placed in a weightless state. Cats when dropped under normal conditions will invariably rotate their bodies longitudinally in midar and land on their feet. This automatic reflex action is almost completely lost under weightlessness.”
