Butterflies in Space

Loading Content


With approximately 20,000 species on Earth, butterflies are among the world's most recognizable and popular insects. In 2009, four painted lady butterflies flew aboard space shuttle Atlantis to the International Space Station, where they grew and lived. Students can use original photos from the mission to conduct open-ended scientific investigations to learn how gravity and microgravity affect the life cycle of painted lady (Vanessa cardui) butterflies.

Developed and conducted by the Center for Educational Outreach, Baylor College of Medicine, in collaboration with BioServe Space Technologies (University of Colorado), and the United States National Aeronautics and Space Administration.

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. While in space, they were monitored continually, with photos and video transmitted hourly to the BCM and BioServe teams on Earth.

The larvae successfully fed, grew, formed chrysalises, and emerged as adult butterflies. The historic space experiment concluded on December 10, 2009, but photos and video from the mission remain available on BioEd Online (see below). We invite you and your students to perform butterfly investigations in your own classrooms, and compare your Earth-based butterflies to those that lived on ISS. The free Butterflies in Space Teacher’s Guide provides instructions for setting up ground-based butterfly habitats and helping students to design their own experiments.

Developed and conducted in collaboration with BioServe Space Technologies of the University of Colorado, and the United States National Aeronautics and Space Administration.
