China's Shenzhou-17 astronauts have opened the hatch of the Tianzhou-7 cargo spacecraft and begun moving supplies and equipment to China's Tiangong space station on January 19. The first task was to move a set of life support devices. The set was placed on the outermost part of the Tianzhou-7 cabin at the Wenchang Spacecraft Launch Site before launch. Tianzhou-7 was loaded with a total of 61 items weighing 473 kilograms, including experiment payloads, units and samples; consumable items; and spare parts.
