A NEW SATELLITE CAN PEER INSIDE BUILDINGS, DAY OR NIGHT (Source FUTURISM)
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. “It turns out that half of the world is in nighttime, and half of the world, on average, is cloudy a former system engineer at the NASA Jet Propulsion laboratory, told Futurism. “When you combine those two together, about 75 percent of Earth, at any given time, is going to be cloudy, nighttime, or it’s going to be both. It’s invisible to you, and that portion is moving around.” On Wednesday, Capella launched a platform allowing governmental or private customers to request images of anything in the world — a capability that will only get more powerful with the deployment of six additional satellites next year.
“There’s a bunch of gaps in how we’re currently observing Earth from space — the majority of the sensors we use to observe earth are optical imaging sensors,” he said. “If it’s cloudy, you’re going to see the clouds, not what’s happening under the clouds. And if there’s not much light, you’re going to have a really hard time getting an image that is useful.” By contrast, Capella can peer right through cloud cover, and see just as well in the daylight as in total darkness. That’s because instead of optical imaging, it uses synthetic aperture radar, or SAR.
