Launch Pads
Rockets cannot be launched from arbitrary places. Instead, dedicated spaceports are selected based on scientific, geographic, and safety criteria to ensure successful and secure missions.
Key Criteria for Selecting Launch Sites
1) Eastward Launch & Proximity to the Equator
- Earth’s rotation generates angular momentum, which provides a natural velocity boost to rockets.
- This momentum is strongest at the equator and reduces toward the poles.
- Launching eastward from near the equator reduces fuel requirement, enhancing efficiency.
2) Inhabited Landmass & Sea Proximity
- Rocket flight paths for geosynchronous (eastward) and sun-synchronous (southward) missions must avoid populated areas.
- In case of launch failure, standby systems may initiate destruct mode to divert debris into the sea.
- Sea crashes are preferred over land to prevent damage and casualties.
3) Geographical Stability & Safety Buffer
- Launch sites must have vast uninhabited land to host explosive-prone facilities and absorb vibrations from launches.
- Stable ground is essential to withstand intense thrust and shockwaves.
4) Other Factors
- Climate conditions, geomagnetic field interference, and year-round accessibility are also considered during spaceport selection.
