Instead of counting on polluters to report their own emissions, York space scientist Brendan Quine has developed a sneaky pollution spy – a tiny gadget that works in space, reported The Globe and Mail Nov. 3. Called the Argus microspectrometer, it picks up on the chemical signatures of carbon dioxide and other greenhouse gases that cause global warming. It will launch into orbit next month on board a microsatellite test-driving tiny instruments. Most tools sent into space cost millions and wind up as nothing more than pollution themselves: giant pieces of obsolete trash orbiting the Earth. Argus costs about $75,000 and can fit in the palm of your hand – making it a cost-effective example of sustainable space instrumentation.
