The Rotifer-B2 investigation aims to explore the effects that spaceflight has on deoxyribonucleic acid (DNA) repair mechanisms of the bdelloid rotifer Adineta vaga. This is achieved by pre-exposing rotifers to high levels of radiation on Earth and then culturing them in Kubik, an on-orbit incubator facility. After exposing rotifers to space conditions inside the International Space Station, the samples are frozen and returned to Earth for postflight analyses. Image courtesy of the University of Namur.
