Polaris Dawn Mission
The Polaris Dawn Mission is a privately funded and operated mission led by Jared Isaacman and SpaceX.
Key Highlights
- Spacewalks, also called extravehicular activities (EVAs), involve astronauts leaving their spacecraft to conduct experiments.
- The mission will test new spacesuits designed by SpaceX to protect astronauts from high radiation levels encountered in the Van Allen Belts.
- The first spacewalk was done by Soviet cosmonaut Alexei Leonov in 1965.
Van Allen Belts
- The Van Allen Belts are two regions of charged particles that surround the Earth and are trapped in its magnetic field.
- Inner Belt: The inner belt results from interactions of cosmic rays with Earth’s atmosphere
- Outer Belt: The outer belt is made up of billions of high-energy particles that originate from the Sun.
- NASA plans to use its upcoming Artemis missions to send astronauts beyond the Van Allen Belts to land on the south pole of the Moon by the end of 2025, and eventually on to Mars.
