China launched the core of its space station in April, and sent three astronauts up in June. Although most experiments slated for Tiangong will involve Chinese researchers, China says that its space station will be open to collaboration from all countries, including the United States. Two will deliver the Wentian (‘quest for heavens’) and Mengtian (‘dreaming of heavens’) modules, which will mainly house scientific experiments (see ‘China’s first space station’). Organoids and dark matterThe experiments being sent up to the new space station encompass numerous fields. Furthermore, as well as housing experiments from researchers, Tiangong is intended to test human space-travel technologies to support China’s space-exploration goals, says Zhang.
