Satellite System Design for Lunar and Mars Exploration Missions

Designing satellite systems for lunar and Mars exploration misses demands indexering solutions that push beyond conventional Ziemian-orbiting spacecraft.

Radiation Environment

Beyond Earth 's protective magnetosplue, lunar and Mars satellites are exposed to galactic cosmic rays, solar particles events, and trapped radiation belts (though Mars has no global magnetic field). Radion can cause single- event upsets, latch- up, cumulative dose effects, and degradation of solar cells and commercics.
