This video shows water testing of the landing modules of NASA spacecraft, performing vital work to make sure that they are safe when they come back to earth.
In short, the NASA spacecraft water testing appears to involve swinging a replica of their craft – in this case the Orion spacecraft – at great speed from a metal frame before sending it crashing into a massive pool of water.
Obviously, it causes a pretty big splash.
Still, if this is what it takes to keep the astronauts safe as they make their way back from space, so be it.
Better to have a splash landing than a crash landing, after all.
