The Expedition 50 crew began activating new science experiments delivered last week aboard the SpaceX Dragon. The various life science studies will study bones and muscles, stem cells, botany and protein crystals.
Rodents delivered aboard Dragon were placed in their habitats over the weekend for the Rodent Research-4 study. That experiment is observing how bone and tissue regenerate in microgravity.
Stem cells were also unloaded from Dragon and stowed in a science freezer. The crew will research the replication of stem cells which may benefit clinical trials on Earth for new disease treatments. Astronaut Peggy Whitson used a specialized microscope to view the stem cells as the experiment got under way over the weekend.
The crew is also exploring how plants grow in space in order to provide food and oxygen for future long-duration missions. Plant samples were removed from a science freezer and placed in the Veggie facility for growth and observation. The spaceflight environment can change a plant’s genetic expression and growth pattern.
High-quality crystals are being grown on the International Space Station that otherwise couldn’t be grown on Earth due to gravity. The crystal samples are being studied for the Light Microscopy Module Biophysics-1 experiment to help researchers design new disease-fighting drugs.
