The delivery of Nasa's Mars Science Laboratory rover, known as Curiosity, to the surface of the Red Planet is a mouth-watering prospect.
The $2.5bn robot is by far the most capable machine ever built to touch another world. Consider just the history of wheeled vehicles on Mars.
In 1997, the US space agency put a toy-sized robot on the surface called Sojourner. It weighed just over 10kg.
This was followed seven years later by the 170kg, twin rovers Opportunity and Spirit. Their instrument complement combined (5kg + 5kg) was equal to the total mass of Sojourner.
Now, we await Curiosity - a 900kg behemoth. Its biggest instrument alone is nearly four times the mass of that teeny robot back in '97.
"It's the size of a Mini Cooper with the wheelbase of a Humvee," is how project scientist John Grotzinger describes the rover.
So, we're expecting great things from Curiosity. A big machine to address some big questions.
