SpaceX’s Polaris Dawn crew has successfully concluded their groundbreaking five-day mission to orbit, culminating in a splashdown in the Gulf of Mexico. The Crew Dragon capsule, carrying four astronauts, landed off the coast of Dry Tortugas, Florida, at 3:37 a.m. ET on Sunday. The Polaris Dawn mission made history by reaching a higher altitude than any human has traveled in five decades and conducting the world’s first commercial spacewalk, a milestone achieved by a privately funded and operated mission.
The mission’s return to Earth highlights the immense challenges associated with space travel, particularly the perilous process of re-entry. To ensure a safe descent, the Crew Dragon capsule executed a “de-orbit burn,” adjusting its orientation to penetrate the densest part of Earth’s atmosphere. As the spacecraft descended, it endured extreme temperatures of up to 3,500 degrees Fahrenheit (1,900 degrees Celsius) due to the intense pressure and friction from slicing through the air at speeds around 17,000 miles per hour (27,000 kilometers per hour). Despite these harsh conditions, the Crew Dragon’s heat shield, located on the bottom of the 13-foot-wide (4-meter-wide) capsule, maintained comfortable temperatures for the crew.

As the capsule decelerated by dragging against the atmosphere, it deployed parachutes to further reduce its speed before touching down in the ocean. Upon landing, rescue teams were quick to secure the spacecraft onto a specialized boat, known as the “Dragon’s nest,” where final safety checks were conducted. Once these checks were completed, the crew was able to safely exit the capsule and begin their journey back to dry land.
The Polaris Dawn crew comprises mission commander Jared Isaacman, the billionaire CEO and founder of Shift4 Payments; his close friend and former US Air Force pilot Scott “Kidd” Poteet; and SpaceX operations engineers Anna Menon and Sarah Gillis. This diverse team embarked on a mission that not only pushed the boundaries of human space travel but also demonstrated the growing capabilities of private space enterprises.
One of the mission’s most notable achievements was breaking an altitude record by reaching an orbit of 870 miles (1,400 kilometers) around Earth. This feat surpassed the previous record set by NASA’s Gemini 11 mission in 1966, which reached 853 miles (1,373 kilometers). The crew’s apogee, or farthest point from Earth, made Anna Menon and Sarah Gillis the first women to fly so far from our planet, marking the farthest any human has journeyed since NASA’s Apollo Program ended in 1972.
The mission also featured a high-risk extravehicular activity (EVA), commonly known as a spacewalk. During the EVA, the Crew Dragon capsule was fully depressurized, allowing Jared Isaacman and Sarah Gillis to exit the vehicle and float in the vacuum of space. Each astronaut spent approximately 10 minutes outside the spacecraft, conducting a series of tests to evaluate the functionality of the EVA suits. The spacewalk proceeded without major issues, with Isaacman remarking, “Back at home we all have a lot of work to do, but from here — looks like a perfect world.” The crew’s time in orbit was further utilized to perform nearly 40 science experiments and research projects, including studies on space adaptation syndrome, a form of motion sickness specific to microgravity environments.
Beyond their scientific endeavors, the crew engaged in unique personal activities during their mission. Sarah Gillis, a trained violinist, brought her instrument aboard and delivered a rendition of “Rey’s Theme” from “Star Wars: The Force Awakens.” This musical performance was transmitted back to Earth using SpaceX’s Starlink satellite network, testing its potential for providing in-space connectivity. Additionally, Anna Menon read excerpts from her coauthored book, “Kisses From Space,” to her family and a group of patients from St. Jude Children’s Hospital, supporting a fundraiser for the renowned medical institution.
The successful return of the Polaris Dawn mission marks the third trip to space for the Crew Dragon capsule named “Resilience.” This spacecraft previously flew the Crew-1 mission in November 2020 and the Inspiration 4 mission in 2021, both of which were significant milestones in private space exploration. The Inspiration 4 mission, also funded by Jared Isaacman, saw him and three crewmates orbit Earth for three days, raising funds for childhood cancer research.
Jared Isaacman’s journey from a high school dropout to a billionaire entrepreneur and space pioneer is nothing short of inspirational. His relentless pursuit of his dream to venture into space, combined with his substantial financial investment, has positioned him at the forefront of the private space industry. Isaacman’s vision for a future where space is accessible to everyone continues to drive advancements in space technology and exploration.
The Polaris Dawn mission not only showcases the technological prowess of SpaceX but also signifies a new era where private individuals and companies play pivotal roles in space exploration. As private space missions become more frequent and ambitious, the boundaries of human achievement in space continue to expand, opening up new possibilities for scientific discovery and human adventure beyond Earth.
