When we talk about Hell on Mars, we’re not suggesting the planet has a fiery underworld waiting to welcome mischievous souls. It’s actually Hellas Planitia, a gigantic crater that makes the Grand Canyon look like a scratch.

This colossal dent, stretching over 2,000 kilometres wide and around 7 kilometres deep, is proof that Mars has had its fair share of cosmic violence. It’s also the third or fourth-largest known impact crater in the Solar System.

Before Italian astronomer Giovanni Schiaparelli gave it the name Hellas (meaning ‘Greece’), it was known as Lockyer Land, named in honour of Sir Joseph Norman Lockyer, an English astronomer who produced "the first really truthful representation of the planet."
