Microsatellites – What Big Eyes They Have

Microsatellites - What Big Eyes They Have - NYTimes.com

PEOPLE already worried about the candid cameras on Google Glass and low-flying drones can add a new potential snooper to the list: cameras on inexpensive, low-orbiting microsatellites that will soon be sending back frequent, low-cost snapshots of most of Earth’s populated regions from space.

They won’t be the first cameras out there, of course. Earth-imaging satellites the size of vans have long circled the globe, but those cost millions of dollars each to build and launch, in part because of their weight and specialized hardware. The new satellites, with some of the same off-the-shelf miniaturized technology that has made smartphones and laptops so powerful, will be far less expensive.

The view from high up is rich in untapped data, said Paul Saffo, a forecaster and essayist. He expects the new satellite services to find many customers.

Insurance companies, for example, could use the satellites’ “before” and “after” views to monitor insured property and validate claims after a disaster. Businesses that update online maps for geologists, city planners or disaster relief officials could be customers, too. The images could also be used to monitor problems like deforestation, melting icecaps and overfishing.

And food companies and commodities traders could use the images to keep track of crops and agricultural yields all over the planet, Mr. Saffo predicted.

But the images are also likely to be viewed as the latest mixed blessing by people already apprehensive of Big Brother-like surveillance in their lives.
