The Van Allen Belts are areas of extremely energetic charged particles surrounding Earth, trapped by the planet’s magnetic subject. These particles, primarily electrons and protons, pose a major radiation hazard. The depth of radiation inside the belts varies, with some areas presenting a a lot higher threat than others. Passing by means of these belts necessitates mitigating the results of this radiation publicity on spacecraft and their occupants.
The existence of those radiation belts was found early within the area age, in the course of the first Explorer missions. Data of the Van Allen Belts has been crucial within the planning of all crewed area missions. The Apollo missions demonstrated the feasibility of traversing the belts with cautious planning of trajectories and applicable shielding of the spacecraft, though the radiation dosage obtained by the astronauts was nonetheless an element of concern. Additional understanding of the dynamic nature of those belts might optimize future missions and scale back potential hurt.
