The Shenzhou-15 mission, the last one in the construction phase of the China Space Station, marks the first crew handover in China's newly completed three-module space station. The crew members will be welcomed by the three Shenzhou-14 taikonauts currently aboard the space station. The two teams will stay together for about a week, before the Shenzhou-14 crew head back to Earth. Join CGTN's special coverage to witness this historic moment.
