The Space Shuttle Atlantis was launched on November 16, carrying not only spare parts for the International Space Station but also two kinds of butterfly larvae — Painted Lady and Monarch caterpillars. The butterflies are going to live in special habitats on the Space Station, and they’re part of an experiment in finding out how living in different gravity affects the development of the larvae. Students across the US will be raising butterflies and comparing them to the ones in space. For updates, photos or video, visit Butterflies in Space.
