The Chinese space station Tiangong-1 continues its inexorable descent towards Earth. Re-entry is expected to occur at some point between March 30 and April 2, though experts have said that these dates are variable.
Tiangong-1 malfunctioned back in 2016. Chinese authorities never provided an explanation as to what exactly happened.
Most of Tiangong-1 (‘Heavenly Palace‘ in Chinese) is expected to burn up in Earth’s atmosphere, though small fragments may reach the surface.
It’s not known exactly what materials were used to build Tiangong, so scientists say it’s not possible to accurately assess any possible dangers posed by debris that actually reaches Earth. Fuel tanks for instance may be hardened structures still containing toxic fuel as they touch down.
