Water Usage in Rocket Launches: Saltwater or Freshwater?
During rocket launches, sound suppression systems are employed to mitigate the intense acoustic energy generated by the engines. These systems utilize large quantities of water to achieve this goal. The type of water used for sound suppression depends on various factors, including the launch site's location and environmental considerations.
Saltwater is commonly used for sound suppression in coastal launch sites. It is readily available and has a high density, making it more effective at absorbing sound waves. However, saltwater can be corrosive to launchpad infrastructure and may pose environmental risks if not properly managed.
Freshwater is an alternative to saltwater and is often used in inland launch sites. It is less corrosive and has a lower environmental impact. However, freshwater can be more challenging to obtain and transport to the launch site.
Recycling Water
Whether saltwater or freshwater is chosen, it is typically recycled for subsequent launches. This practice reduces the amount of water required and minimizes environmental impact. Recycled water undergoes filtration and treatment to maintain its quality and effectiveness.
