SpaceX is gearing up for an exciting new private mission at the end of this month. The Polaris Dawn mission is the brainchild of billionaire and Shift4 founder, Jared Isaacman, who purchased three flights from SpaceX in 2022 for his Polaris Program dedicated to human spaceflight endeavors. The mission, set to launch from Florida on August 26, marks the first attempt by a private venture to have astronauts conduct a spacewalk.
Jared Isaacman will once again take the reins as the mission commander, with a crew of four members accompanying him. Scott Poteet will serve as the pilot, with Anna Menon and Sarah Gillis fulfilling the roles of medical officer and mission specialist, respectively. The multi-day trip will not lead to any particular destination but will involve a free-flying mission that traces orbits far from Earth. Isaacman stated that the crew will be venturing to a high altitude that humans have not visited in over half a century.
While extravehicular activities (EVAs) have been a standard part of NASA missions for maintenance outside the International Space Station, no private entity has attempted a spacewalk before. Isaacman acknowledged the risks associated with a spacewalk, referring to the experience as being “surrounded by death.” To prepare for this unprecedented event, the crew has undergone extensive training and simulations in vacuum chambers to mimic the conditions of space.
Isaacman outlined the detailed schedule for the mission, which will span up to five days in space. The first day will involve assessing the risk from micrometeorite orbital debris to determine the optimal launch time. After achieving an orbit of 190 kilometers by 1,200 kilometers, the crew will conduct thorough checks on SpaceX’s Dragon capsule Resilience to ensure it is fault-free before ascending to an altitude of 1,400 kilometers. Additionally, the spacecraft will pass through the high radiation zone known as the South Atlantic Anomaly for safety checks.
Day two will focus on scientific experiments and preparations for the spacewalk, totaling approximately 40 experiments. The crew will test the EVA suits in microgravity conditions to ensure their functionality. The third day will be dedicated to the much-anticipated spacewalk, with all four crew members taking part in the process. Isaacman emphasized that the spacewalk is a critical test and development phase to gather insights into the suit’s performance and operational procedures.
A key component enabling the spacewalk is SpaceX’s cutting-edge spacesuits. Developed after extensive testing and iterations, these suits are designed to facilitate future missions to the moon, Mars, and other celestial bodies. Isaacman highlighted the importance of continuous innovation in advancing spacesuit technology for various space exploration purposes.
SpaceX’s Polaris Dawn mission represents a significant milestone in private spaceflight endeavors. By pushing the boundaries of what is possible in space, the mission not only aims to inspire but also sets the stage for future developments in human space exploration. With the spacewalk being live-streamed and numerous cameras documenting the event, Polaris Dawn promises to captivate audiences worldwide and pave the way for new possibilities in space travel.
