The Correct Option is C
Solution and Explanation
In aerospace engineering, the lifespan of a geostationary communication satellite is primarily determined by the quantity of onboard fuel available. This is because:
- Fuel Usage: The satellite uses fuel for station-keeping maneuvers to maintain its position in the geostationary orbit. Over time, the satellite's fuel reserves are depleted, limiting its operational life.
- Orbital Corrections: Regular adjustments are required to counteract gravitational perturbations and maintain the satellite's designated orbital slot.
- Fuel as a Finite Resource: Once the onboard fuel is exhausted, the satellite can no longer maintain its geostationary position, leading to the end of its functional life.
Other factors like the working life of electronic circuit boards, atmospheric drag, and meteorite impacts may influence satellite longevity, but fuel is the primary limiting factor in the operational duration of geostationary satellites.
