The event when a spacecraft or missile lands in water, often after a journey in space.
The astronauts celebrated their successful splashdown after returning from the International Space Station.
Splashdown → It is formed from "splash" (of imitative origin, representing the sound of something hitting water) and "down" (meaning downward or to a lower position). The word "splashdown" refers to the landing of a spacecraft in water, creating a splash as it descends down into the water.
Imagine a spacecraft making a big splash as it lands in the water — that's what splashdown means.
