Painted Lady Butterflies in Space! On November 16, 2009, larvae that hatched six days earlier flew aboard Space Shuttle Atlantis to the International Space Station. The larvae successfully fed, grew, formed chrysalises, and emerged as adult butterflies. The historic space experiment concluded on December 10, 2009. However, photos and video from the mission will continue to be available on the project website for students to compare to their live organisms on Earth.
