Four “butterflynauts” have emerged on the International Space Station. They are part of a suitcase sized educational experiment that was rocketed to space on Nov. 16 on space shuttle Atlantis as part of the STS-129 mission. Students of all ages and the public are invited to follow the tiny crew’s development from larvae to adult butterflies in the microgravity of space.

In over 100 classrooms across the U.S., students have set up habitats and are replicating the space experiment. Their objective is to compare the growth and behavior of ground-based butterfly larvae and adult butterflies with those living in the microgravity environment of space. New pictures and videos and Powerpoint slides are available almost daily.

A free Butterflies in Space teacher’s guide can be downloaded from BioEd Online at the Butterflies in Space website here. The project is sponsored by National Space Biomedical Research Institute.

Initial results show that there appears to be no difference in the development rates of these butterflies in a microgravity environment as compared to Earth’s gravity, which is a fairly significant finding. While microgravity environment has obvious impacts on human health and physiology, relatively little is known about how microgravity whould effect human growth and development. While there are major differences between humans and butterflies, basic cellular divisions in follow similar processes. Therefore, the success of the butterfly experiment in space indicates that a human embryo could potentially survive and develop normally in space even in the absence of gravity.
