First, a space junk update. By the time you listen to this, a space junk update.

Cosmos 482, which the USSR launched back in 1972, was meant to follow the successful

probes Venera 7 and Venera 8 in landing on and studying Venus.

But a suspected engine malfunction meant that Cosmos 482 never achieved enough velocity to

escape Earth's orbit. It's been orbiting our planet ever since and losing altitude along the

way. Some of Cosmos 482 already fell back down to Earth decades ago, but one last big chunk has held on

for more than half a century. Last week, researchers said Cosmos 482 would probably make its

uncontrolled descent over the weekend. Its potential landing zone stretched from 52 degrees north to

52 degrees south latitude, which covers pretty much everywhere except for Antarctica and, like, places where you can

see the northern lights. There's a chance that the 1,000 dish or so pound lander, which was

designed to withstand Venus's atmosphere, will hit Earth in one piece. That could be bad if it
