Genes in Space-11 studies how spaceflight may activate retrotransposons, which are DNA fragments that copy and paste themselves throughout a genome, leading to cancer and other diseases. This investigation tests methods for detecting and measuring retrotransposons that may be adapted to detect other RNAs, including those of viruses that cause illness. Understanding the behavior of retrotransposons in microgravity may shed light on the genetic risks, including cancer, from space travel and support development of ways to protect astronauts during missions.
