Melbourne's Space Roo

If you happen to be flying over a Melbourne suburb in the near future and you see a giant white kangaroo, don’t be alarmed. It’s science.

The 32-metre by 18-metre cardboard ’roo is part of an experiment to measure albedo, the amount of light reflected back into space as part of a global climate change experiment.

The American space agency NASA will use four satellites that regularly sweep through Australian skies to photograph the kangaroo on Tuesday morning at Monash University's Clayton campus.

The satellites will measure how much of the sun's warmth would be lost if the planet were covered in thick white cloud, one climate change scenario. The pictures will be compared with satellite photos taken a year ago.
