A Soviet-era spacecraft has plunged to Earth, more than a half-century after its failed launch to Venus. The half-ton spacecraft fell out of orbit on Saturday.

The 50-plus-year-old spacecraft has been trapped in Earth orbit for decades. Now, it’s expected to fall back home.

Predictions for the earthly plunge of a wayward Soviet era Venus space probe are narrowing as the old spacecraft is expected to crash back to Earth Friday night.
