Russian rocket part makes uncontrolled re-entry into Earth’s atmosphere

       Officials have confirmed the part landed in the Pacific Ocean. It was from the third test flight of the Angara-A5 heavy-lift rocket, launched from the Plesetsk Cosmodrome in north western Russia on December 27

       However, writing on Twitter astronomer John McDowell said the risk was low.

       He said:”To be clear, I do NOT regard this object as a significant risk.

       “Reentries for a object with dry mass of about 4 tonnes may see some debris reach the ground, but not much.”

       According to Russian media outlet Tass the purpose of the launch was to test a new upper stage rocket, called the Persei booster for the first time.

       Initially the launch was declared a success according to officials

       Later on however the booster appeared to suffer from engine failure.

       This prevented the launcher from reaching a higher than low- Earth orbit.

       On Wednesday evening the 18th Space Control Squadron confirmed the re-entry had occurred at 4.08pm Eastern Standard Time over the South Pacific.

       No other details were provided.

       It’s common for debris from space to burn up in the atmosphere.

       However large parts can be dangerous depending on where they land.

       Space debris has become a controversial political issue.

       In November the US said that debris from a Russian anti-satellite missile test had forced the crew on the International Space Station (ISS) to shelter as a precaution
