Why do astronauts keep altitude beneath Van Allen radiation belts when doing space walks?


Expert Answer

Step 1

The Van Allen radiation belts are the reasons of harmful radiations or the charged particles. The Van Allen radiation belts trap many harmful radiations such as protons, alpha- particles, and other charged particles.

The belts are located in the inner region of Earth's magnetosphere. The belts trap energetic electrons and protons.

The belts endanger satellites, which must have their sensitive components protected with adequate shielding if they spend significant time near that zone.

Step 2

Spacecraft travelling beyond low earth orbit enter the zone of radiation of the Van Allen belts. Beyond the belts, they face additional hazards from cosmic rays and solar particle events.

Solar cells, integrated circuits, and sensors can be damaged by radiation. Geomagnetic storms occasionally da...
