A few months ago, a company called Capella Space launched a satellite capable of taking clear radar images of anywhere in the world, with incredible resolution — even through the walls of some buildings.
And unlike most of the huge array of surveillance and observational satellites orbiting the Earth, its satellite Capella 2 can snap a clear picture during night or day, rain or shine...a capability that will only get more powerful with the deployment of six additional satellites next year. Is that creepy from a privacy point of view? Sure...
The satellite beams down a powerful 9.65 GHz radio signal toward its
target, and then collects and interprets the signal as it bounces back
up into orbit...
Possibilities abound. Train two SAR satellites on the same target and they can actually image targets in three dimensions down to minute differences in height. more
