Keep looking up Sunday night and Monday morning because a one ton research satellite will be plummeting down to Earth but scientists can't say where it will land.
The European Space Agency (ESA) say the satellite is spiralling steadily downwards and will break apart
50 miles above the Earth and the smaller parts will burn up in the atmosphere however they expect several dozen fragments weighing about the same as a car engine will make it down to hit the surface.
Professor Heiner Klinkrad from the ESA said: 'At present we can not say where the re-entry is going to happen except that it is not going to happen north of the 85 northern latitude or south of 85 southern latitude. We are in contact with national civil protection agencies throughout Europe, of ESA member states, so they get all the information we have on the re-entry prediction and that also includes information on emergencies in case parts of the satellite fall on inhabited areas'.
I'm sure the ESA will be able to narrow down where residents have to don hard hats but maybe if we all keep our fingers crossed and wish with all our might, it will crash thorough the roof of 10 Downing Street.
