Happy Birthday to Opportunity, the Mars rover which landed safely three years ago today. I was sitting in a York car park when I heard the news, and had to cheer. Despite the design aim of 90 sols (Mars days), it’s still going 1000 sols later, and has travelled 6.1 miles. Brilliant. Far from becoming decrepid in its old age, it’s actually getting smarter due to software upgrades.
Is there anything cooler than space probes?
