Sea Levels

Sea level is the average height of the ocean's surface. In the context of space and astronautical engineering, sea level is used as a reference point for measuring altitude and determining the performance of rockets and spacecraft during launch and ascent. The altitude of a launch site is typically measured relative to sea level, and the performance of a rocket engine is affected by the air pressure and temperature at sea level. Additionally, sea level rise due to climate change is a concern for space infrastructure located near coastlines, such as launch sites and ground stations. Rising sea levels could lead to flooding and damage to critical infrastructure, as well as increased erosion and changes to the local climate.
