Study Notes
- SpaceX achieved a new milestone on September 15, 2024, with the successful completion of Polaris Dawn.
- Polaris Dawn is the first of three commercial space missions under the Polaris program.
- The five-day flight included an all-civilian astronaut crew.
- The crew set several space altitude records.
- The mission included a pioneering spacewalk.
Crew
- The Dragon capsule lifted off from Florida's Kennedy Space Center on September 10, 2024.
- Jared Isaacman, a billionaire entrepreneur and funder of the Polaris missions, was the mission leader.
- SpaceX employees Sarah Gillis and Anna Menon were part of the crew.
- Retired US Air Force pilot Scott Poteet was also a crew member.
Altitude Record
- On September 11, 2024, the spacecraft reached its peak altitude of 870 miles (1,400 km) above Earth.
- This is the highest human spaceflight since the Apollo Moon missions.
- The previous record was held by NASA's Gemini 11 mission at 853 miles (1,372 km) in 1966.
- Sarah Gillis and Anna Menon are the first women to fly so far from Earth.
Radiation Assessment
- The high altitude was reached to assess the impact of increased radiation levels on the Dragon capsule and crew.
- This data is crucial for preparing future missions to the Moon and beyond.
Civilian Spacewalk
- The spacecraft descended to a cruising altitude of 435 miles (700 km) above Earth.
- On September 12, 2024, Isaacman and Gillis prepared for the first-ever civilian spacewalk.
- They wore new SpaceX spacesuits and underwent a "pre-breathing" routine to prevent decompression sickness.
Spacesuit Details
- The astronauts were tethered to the spacecraft with a 12-foot-long cord for oxygen supply.
- The new spacesuits lacked traditional life support systems.
- Isaacman and Gillis performed a 10-minute spacesuit functionality test.
Mission Conclusion and Research
- The Dragon capsule splashed down in the Gulf of Mexico at 3:37 a.m. ET on September 15.
- Isaacman and the crew are undergoing medical tests to assess the effects of space travel.
- The findings will aid in developing strategies to protect astronauts on future deep-space missions.
