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.
