What was the Polaris Dawn mission?
What was the Polaris Dawn mission?
SpaceX's Polaris Dawn was a five-day civilian space mission that aimed to break altitude records and test the limits of human spaceflight.
What altitude record did the Polaris Dawn mission break?
What altitude record did the Polaris Dawn mission break?
The Dragon capsule, carrying a crew of four civilian astronauts, reached a height of 870 miles (1,400 km), surpassing the highest point reached by any human spaceflight since the Apollo missions to the Moon. This surpassed the previous record held by NASA's Gemini 11 mission.
What scientific benefit did reaching the record altitude serve?
What scientific benefit did reaching the record altitude serve?
The primary objective of reaching this high altitude was to assess the impact of increased radiation levels on the Dragon capsule and its crew. This data will be valuable in planning future missions to the Moon and beyond.

Study Notes
SpaceX's Polaris Dawn Mission
- SpaceX's Polaris Dawn mission, the first of three under the Polaris program, successfully completed a five-day flight.
- The mission involved a crew of all civilian astronauts.
Mission Details
- The Dragon capsule launched from Florida's Kennedy Space Center on September 10, 2024.
- The mission leader was Jared Isaacman, a billionaire entrepreneur.
- The crew also included SpaceX employees Sarah Gillis and Anna Menon, and retired US Air Force pilot Scott Poteet.
- The spacecraft reached a peak altitude of 870 miles (1,400 km) above Earth on September 11, 2024, surpassing the previous record held by NASA's Gemini 11 mission.
- This high-altitude flight was designed to assess the impact of increased radiation levels on the Dragon capsule and crew, vital for future lunar and deep-space missions.
- The spacecraft then descended to a cruising altitude of 435 miles (700 km).
First Civilian Spacewalk
- On September 12, 2024, Isaacman and Gillis conducted the first-ever civilian spacewalk.
- This was a critical test of the new SpaceX spacesuits, which lacked traditional life support systems.
- The astronauts were tethered to the spacecraft by a 12-foot-long cord providing oxygen.
- The spacewalk lasted 10 minutes and was successful.
Mission Conclusion
- The mission concluded on September 15, 2024, with the Dragon spacecraft and crew splashing down into the Gulf of Mexico.
- Post-flight medical assessments are underway to study the effects of space travel on the astronauts.
