Space debris from failed rocket misses New York City by minutes
A Chinese rocket has crashed down to Earth, missing New York by minutes.
The Long March-5B rocket, an unmanned prototype craft launched into space on 5 May, fell down and came around 13 minutes of hitting the city.
CNN reported that the rocket launched from the Wenchang Space Launch Center in the Hainan province in South China.
The rocket experienced a mysterious malfunction on its first flight, but nevertheless returned to China as planned.
The spacecraft, which had been in development for 10 years with the intention to carry large payloads into low-Earth orbit, was over 50 meters long and weighed 849 tons when it took off.
Usually when a rocket launches, the first stage provides the majority of the thrust to get the craft into orbital velocity before dropping into the ocean. A second stage then activates, pushing the rocket’s payload into orbit.
However, the rocket had difficulty breaking out of the Earth's atmosphere.
Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, told The Independent that: “Even in space there's a thin bit of atmosphere left. Objects in low orbit travel at 18000 mph, so even a tiny bit of air makes a huge headwind. This causes 'orbital decay' - the satellite's orbit gets lower and lower over time, into the denser atmosphere where the headwind is even bigger.
"Eventually it gets to the point where the heating from friction melts the metal and causes the object to break up and lose enough speed to crash towards Earth. For smaller satellites, they melt entirely and nothing reaches the ground.”
McDowell tweeted that it was the “most massive object to make an uncontrolled re-entry since the 39-tonne Salyut-7 in 1991”.
Tracking objects travelling at such high speed is challenging, and during the descent of the rocket it was predicted that the potential re-entry areas were near Australia, the US, and Africa.
