There were times that summer when parts of our traditionally green and pleasant land did, indeed, look more like the surface of Mars: arid and monochrome. When on a winning streak, you should make the most of it. They looked just like the ones we saw  also in colour  after NASA's Viking spacecraft did the same trip in 1976. In such situations, you don't play by the rule book: you go for broke. Spot the difference!
