China’s space station Tiangong is almost complete. The third and final module is scheduled to launch into low Earth orbit on Monday [10/31/2022]. The station, only the second laboratory in orbit, is expected to host more than 1,000 scientific experiments over its lifetime of at least 10 years. These include studying the effects of microgravity on living tissues and the behaviour of fires. ...

Researchers from other countries will also have access to the orbiting laboratory, says Brad Tucker, an astrophysicist at the Australian National University in Canberra. China has selected nine international experiments to fly to the outpost through a collaborative project with the United Nations, developed by researchers from Japan, Russia, India and Mexico, among others. ..."

China’s space station is almost complete — how will scientists use it? Tiangong will host more than 1,000 experiments over a decade, including attempts to reproduce results from the International Space Station.
