A new satellite can peer inside some buildings, day or night
Cloud cover, and even in some cases walls, can't block this ultra-precise satellite's view.

SAR works similarly to how dolphins and bats navigate using echolocation. 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. And because the satellite is sending down its own signal rather than passively capturing light, sometimes those signals can even penetrate right through a building’s wall, peering at the interior like Superman’s X-ray vision.
