Five days after the successful docking of Shenzhou 9 with Tiangong 1, for the first time, astronauts have manually changed the attitude control for both modules.

Liu Wang turned off the control system on Tiangong 1 around noon Friday Beijing time. When Shenzhou-9 took charge of the flight of the joint space modules, Liu Wang tested three different kinds of positioning of the modules.

When they aren’t controlling the direction of the mission, the three astronauts are getting used to space life. On Thursday night, they had the chance to talk on the phone with their families.

Liu Wang even played harmonica for his wife to celebrate her birthday. But the most active member among the three is Liu Yang, the only female astronaut on the mission. Video footage shows that she often practices somersaults in the lab.

According to the center, the three astronauts are getting prepared for the first-time crew-guided docking on Sunday.
