SpaceX’s Polaris Dawn Mission: First Commercial Spacewalk (GS Paper 3, Science & Technology)
Introduction
- SpaceX is set to launch the Polaris Dawn mission, a groundbreaking commercial space project, soon.
- This mission represents a significant advancement in civilian space travel, featuring the first private extravehicular activity (spacewalk) with an all-civilian crew.
Recent Context and Significance
- The mission, scheduled no earlier than July 31, 2023, follows SpaceX’s Inspiration4 mission, which was the first all-civilian spaceflight in September 2021.
- Polaris Dawn is significantly funded by U.S. billionaire Jared Isaacman, highlighting the growing influence of private individuals and organizations in space exploration.
Objectives and Innovations
- Polaris Dawn aims to achieve several key milestones. Foremost among these is the first private spacewalk.
- The mission will also conduct scientific research critical to human health in space, including low-gravity experiments.
- Additionally, the mission will test the integration of Starlink WiFi into their spacecraft, potentially revolutionizing communication for future space missions.
Mission Details
- The mission will utilize the SpaceX Crew Dragon capsule, previously used for crewed spaceflights.
- Jared Isaacman is among the four crew members set to embark on Polaris Dawn.
- The mission targets a high orbit of approximately 700 kilometers above Earth, the highest manned flight since the Apollo missions.
- The crew will spend about five days in orbit, providing ample time to conduct planned experiments and the historic spacewalk.
- Success of the Polaris Dawn mission could significantly influence future policies and advancements in international space exploration, enhancing the viability of civilian space travel and pioneering new technologies.
