With manned spaceflight becoming possible in the 1960s, animals became less common on missions. However in the decades since, hundreds of animals from tortoises to mice have taken part in missions as part of scientific studies. Even as recently as May, 2011 spiders were taken into orbit on the final flight of Space Shuttle Endeavor to study the effects of zero gravity on their behavior.
