A space commentator says a rocket could make landfall in Cork tomorrow.
A failed Russian Venus probe, launched back in 1972, is finally expected to reenter Earth's atmosphere.
The craft never reached Venus and has been stranded in orbit around Earth for over 50 years.
It has a one metre-wide titanium shell lined with thermal insulation, and weighs 495 kilograms.
Space commentator Leo Enright says the rocket could be visible at around 8.30am tomorrow morning:
"People should be watching out tomorrow morning at 8.30am, have a look at the sky, if you're in Cork city it will appear directly above you if you're standing on Patrick's Street in Cork.
