CAPE CANAVERAL, Fla. (AP) — A Soviet-era spacecraft meant to land on Venus in the 1970s is expected to soon plunge uncontrolled back to Earth. It’s too early to know where the half-ton mass of metal might come down or how much of it will survive reentry, according to space debris-tracking experts.

A failed Soviet-era spacecraft that was meant to land on Venus is expected to reenter Earth’s atmosphere some time this month.

The spacecraft suffered an engine anomaly that left it stuck in Earth's orbit for decades, and now it's slated for an uncontrolled reentry.
