Polaris Dawn Flight Day 4 Update After an exciting and historic spacewalk on Thursday, September 12, the crew spent the majority of their Flight Day 4 focused on science and research. Polaris Dawn partnered with 31 institutions from across the world to create a robust and diverse science research portfolio throughout their time in space. A few of the studies the crew has focused on since arriving on-orbit have included assessing the effects of microgravity on the human airway and veinous system in addition to examining how blood flow restriction alters blood flow in space using ultrasound and smart watches. As humans become a spacefaring civilization, having the proper support system in the event of medical emergencies is key. The Polaris Dawn crew tested out Tempus Pro, a commercial off-the-shelf device that can collect and integrate measurements of health – including blood pressure, heart rate, respiration rate, temperature, and more – along with ultrasound imaging capabilities. The crew was able to use it to assess and compare vital sign data collected pre-flight to that collected during their time on-orbit. The crew is also working with several partners to study the effects of microgravity on ocular health to help contribute to both preventative and post-diagnosis treatments associated with Spaceflight Associated Neurocular Syndrome (SANS), which many astronauts have experienced from their time in space. Check out the science and research video we shared earlier today to learn more about what the crew has been up to! The crew also continued to test and demonstrate Starlink aboard Dragon. One of the biggest tests of connectivity includes the ability to quickly share files. Earlier in the week, the crew recorded Mission Specialist Sarah Gillis playing “Rey’s Theme” by John Williams on the violin. Once complete, the crew successfully sent the files down to Earth over Starlink to help create this special music event named "Harmony of Resilience." Teams on Earth synced Gillis’s video and audio with various recorded orchestral performances around the globe, including in Los Angeles, which was attended by legendary composer John Williams and the entire Polaris Dawn crew. These performances were conducted from mid-2023 to early 2024. The crew wrapped their day and are gearing up for their final day on-orbit, during which more research and Starlink testing will be conducted.
