Tianzhou 10 Delivers Almost 7 Tons of Supplies to Tiangong

China’s Tianzhou 10 cargo freighter launched May 10 from Wenchang on a Long March 7 rocket and docked with the Tiangong space station about five hours later, delivering roughly 6.9 tons of cargo (about 6.3 metric tons). The haul includes about 280 kg of scientific experiments, 700 kg of propellant, and the last of three new spacewalking suits, along with other supplies. Tianzhou 10, like its predecessors, is a disposable freighter that burns up on reentry after its mission. Tiangong’s three-astronaut crew (Zhang Lu, Wu Fei and Zhang Hongzhang) remain aboard the station with Shenzhou 21.
