Mars: is it any good?

"Is there life on Mars?" asked Bowie (currently on 4.5/5) in 1971.  Unfortunately for Bowie, an enthusiastic supporter of alien life forms throughout his career, the answer was that a lack of a magnetosphere and the extremely thin atmosphere of Mars make life impossible, not to mention the fact that the planet has little heat transfer across its surface, poor insulation against bombardment and the solar wind, and insufficient atmospheric pressure to retain water - the basis of life -  in a liquid form.
Don't worry though, the soil on Mars contains vital nutrients such as magnesium, sodium, potassium and chloride, all of which are suitable for the growth of asparagus. So if, like Bowie in his latter years, you enjoy growing your own vegetables - and aren't too worried about the cumbersome space suit you'd have to wear to avoid certain death - give Mars a healthy rating below!
