Europe 's HERA mission is aiming to find out how much of an impact a NASA spacecraft made when it deliberately smashed into an asteroid in 2022 in the first -ever test of our planetary defences.

HERA flew as close as 5,600 kilometres from the Martian surface, at a speed of 33,480 kilometres an hour .

The spacecraft used the planet's gravity to get a "kick" that also changed its direction and saved fuel.

The lumpy, 12.5 kilometre -wide moon is the smaller and less well-known of the two moons of Mars .
