In early May, China launched its Long March-5B rocket. The mission is successful: "the test was a complete success," said the Chinese society of aerospace science and technology (CASC).
After a week in orbit, it is the central part of the rocket which has passed through the Earth's atmosphere. The debris landed in the Atlantic Ocean, west of the African continent.
The last time a debris of this size made an uncontrolled entry was in 1991, according to tweet by astrophysicist Jonathan McDowell. "With its 17.8 tonnes, it is the most massive object to make an uncontrolled re-entry since the Salyut-7 of 39 tonnes in 1991, unless there are OV-102 Columbia in 2003". An already full discharge
The Chinese aerospace science and technology company announced that: "The new Chinese Long March-5B carrier rocket made its maiden flight on Tuesday, sending the test version of China's next generation manned spacecraft." With the ambition to send astronauts to the Moon and install a space station. The Long March-5B is approximately 53.7 meters long, with a central stage of 5 meters in diameter and four boosters of 3.35 meters in diameter.
The landing of space debris in oceans is nothing new. In the heart of the Atlantic Ocean, Nemo point is considered to be the most isolated area on earth. The first coasts are just under 3000 km. This area is a cemetery of space debris. It hosted between 250 and 300 spacecraft.
