China’s out-of-control Tiangong-1 space lab has re-entered Earth’s atmosphere, landing in middle of the South Pacific Ocean near world’s ‘spacecraft cemetery or graveyard’.
Tiangong-1 (Heavenly Palace or Celestial Palace-1) was China’s first prototype space station or space laboratory.
It was placed in orbit in September 2011 as part of China’s efforts towards building its own space station independent and unconnected to any other international space-active countries.
During its lifespan, Tiangong-1 had served as both manned laboratory and experimental testbed to demonstrate orbital rendezvous and docking capabilities during its active operational life.
It was first operational component of Tiangong program, which aims to place a larger, modular station into orbit by 2023, the time when US-led International Space Station is expected to go out of service.
Tiangong-1 was originally planned to be decommissioned in 2013 but its mission was repeatedly extended. It reportedly stopped functioning in 2016.
China has launched a second lab, Tiangong-2 in 2017 which continues to be operational.
