The Polaris Dawn Mission took major steps in the advancement of human spaceflight. During the 5-day flight, Commander Jared Isaacman and Mission Specialist Sarah Gillis made history by performing the first-ever commercial spacewalk. Since the Crew Dragon spacecraft doesn’t have an airlock, the entire capsule was depressurized, exposing all four crew members to the dangers of space. Isaacman stepped out first, spending nearly eight minutes outside, followed by Gillis, making her the youngest person to participate in a spacewalk. Meanwhile, Pilot Scott “Kidd” Poteet and Mission Specialist & Medical Officer Anna Menon remained inside the capsule with their suits for protection, monitoring systems and ensuring the safety of the operation. This groundbreaking event not only marked an important milestone in commercial spaceflight but also demonstrated the capabilities of SpaceX’s newly designed EVA suits, paving the way for future missions beyond Earth. The Polaris Dawn mission also tested Starlink’s laser technology in space, ensuring fast and uninterrupted communications for future missions to the Moon, Mars, and beyond. Mission Specialist Sarah Gillis became the first to play a violin in space, creating a global musical message called “Harmony of Resilience,” supported by legendary Star Wars composer John Williams and musicians around the world. While orbiting Earth, the crew performed important health research to help us understand how space travel affects humans. They used ultrasound to check for gas bubbles in the blood, studied how space radiation impacts the human body, and gathered biological samples for long-term studies. They also researched vision problems astronauts can experience during long missions. Polaris Dawn worked with top research institutions and universities to carry out this critical science. The mission explored how to make space accessible and safer for more people. They tested a continuous glucose monitor to ensure diabetic astronauts can safely travel in space. The crew also experimented with performing life-saving CPR in microgravity conditions, which is crucial as more people travel to space. Finally, they investigated how astronauts adapt back to gravity after space missions and tested whether medications remain useful in space conditions.
