SpaceX is gearing up to launch an unprecedented all-civilian crew on a bold orbital expedition, signaling a significant milestone in space exploration. The Polaris Dawn mission, spearheaded by billionaire entrepreneur Jared Isaacman, is scheduled for liftoff from NASA’s Kennedy Space Center in Florida. The launch is set for 3:38 am with contingency options available if needed. The weather conditions are looking favorable, with SpaceX planning to provide a live webcast of the event. The mission will see the SpaceX Dragon capsule riding atop a Falcon 9 rocket, reaching a peak altitude of 870 miles – surpassing the heights of any crewed mission in more than fifty years.
Mission commander Jared Isaacman will lead a team of four through the groundbreaking mission, which includes the first commercial spacewalk by private citizens. The crew consists of mission pilot Scott Poteet, a retired US Air Force Lieutenant Colonel; mission specialist Sarah Gillis, a lead space operations engineer at SpaceX; and mission specialist and medical officer Anna Menon, also a lead space operations engineer at SpaceX. The crew members underwent extensive training spanning over two years, encompassing simulations, skydiving, centrifuge training, scuba diving, and even summiting an Ecuadoran volcano in preparation for the mission.
The Polaris Dawn mission is part of the larger Polaris program, a collaborative effort between Jared Isaacman, founder of tech company Shift4 Payments, and SpaceX. This initiative aims to develop and test new technologies and operations in alignment with SpaceX’s ambitious goal of enabling humanity to explore the cosmos. Isaacman remains tight-lipped about the total investment in the project, although reports suggest a substantial sum was paid for the SpaceX Inspiration4 mission in September 2021, the precursor to the current all-civilian orbital mission.
Polaris Dawn will venture into the Van Allen radiation belt, a region abounding with high-energy charged particles that present health risks to humans over prolonged exposure. The crew will orbit nearly three times higher than the International Space Station, providing them with a unique vantage point of our planet. The mission is poised to set new records for commercial space exploration, pushing the boundaries of human achievement in the realm of space travel.
The crew of Polaris Dawn will engage in a series of experiments aimed at enhancing our understanding of human health during extended spaceflights. These include innovative tests such as utilizing contact lenses embedded with microelectronics to monitor changes in eye pressure and shape continuously. Additionally, the crew will partake in testing laser-based satellite communication to optimize space communication speeds between the spacecraft and SpaceX’s Starlink constellation of internet satellites.
Following six days in space, the Polaris Dawn mission will culminate in a splashdown off the coast of Florida, with a SpaceX recovery vessel on standby. The subsequent Polaris missions are set to continue exploring new frontiers, with the second mission incorporating another Dragon capsule and the third mission slated to be the inaugural crewed flight of Starship, SpaceX’s groundbreaking next-generation rocket. The Polaris program is a testament to the spirit of innovation and exploration driving humanity towards the stars, redefining what is possible in the realm of space exploration.
