Nasa has been practising retrieving this spacecraft from the ocean

Practice makes perfect they say, and so the US Navy and Nasa have been repeatedly retrieving this spacecraft from the ocean.

Why? Because Orion is part of the craft designed to take humans to the moon, asteroids and, eventually, to Mars in the 2030s.

And in December, it will splash down off the coast of Baja California, Mexico after reaching an altitude of 3,600 miles (5,790 kilometres).
