Scientific agencies around the world continue to try and predict where the debris from the Chinese CZ-5B rocket will eventually land, providing maps with possible trajectories.
According to earlier calculations by Russia's Roscosmos, the rocket could enter Earth’s atmosphere as soon as 9 May, somewhere in the Pacific Ocean.
On early Sunday, Roscosmos estimated that the potential zone of risk includes big cities like Madrid, Rome, Cairo, Riyadh and Canberra.
CelesTrack released a map, also available in a 3D-version, showing several possible paths for debris to fall and also a tracker of the CZ-5B. Corridors pictured on the map also show decaying altitude, starting at yellow below 150 km and then red below 146 km.
Space-Track.org estimated that the rocket body's re-entry will occur at around 2:00 GMT on 9 May, somewhere above the Mediterranean sea.
The body of the rapidly tumbling Chinese rocket, weighing some 20 tons, is hurtling in the atmosphere at some 27,000 kilometres per hour (~17,000 miles per hour). The launch rocket earlier delivered part of a Chinese orbital station Tiangong (“Heavenly Palace”) into near-Earth orbit.
