A big robotic arm on China’s house station has efficiently grasped and maneuvered a cargo spacecraft in a vital check forward of upcoming module launches.
The 33-foot-long (10 meters) robotic arm on the Tianhe module of China’s new Tiangong house station took maintain of the Tianzhou 2 provide ship and moved it round 20 levels, earlier than returning it to the ahead port on Tianhe’s docking hub.
The 47-minute operation started at 5:12 p.m. EST on Wednesday, Jan. 5 (2212 UTC, 6:12 am Beijing time Jan. 6) to check the procedures and gear wanted for the addition and motion of bigger house station modules. The profitable trial was very important to the China Nationwide Area Administration’s plan to finish development of its house station later this yr.

China’s subsequent house station modules, named Mengtian and Wentian, are scheduled to launch on separate Lengthy March 5B rockets within the coming months and dock with the orbiting Tianhe. The robotic arm will then want to understand the modules, every with a mass of greater than 44,100 kilos (20,000 kilograms), and maneuver them from the ahead port to radial ports.
“It is a know-how during which we should obtain a breakthrough in the middle of constructing your complete house station,” Shi Jixin, deputy chief designer of the house station on the Fifth Academy below the China Academy of Area Know-how (CAST), instructed CCTV.
Groups on the bottom simulated the robotic arm check nicely prematurely of the Wednesday operation. The robotic arm crawled to a berth port close to the Tianhe docking hub two days previous to the check. From this place, it grabbed Tianzhou 2 by attaching to an adapter port on the cargo spacecraft.
The robotic arm has performed a component in spacewalks outdoors Tianhe, serving to to maneuver suited astronauts round to hold out their duties. However this was the primary time the arm has been used on a big spacecraft.
The addition of two new modules will full China’s T-shaped, three-module Tiangong house station. Mengtian and Wentian are devoted to internet hosting a variety of science experiments but in addition embrace an airlock for extravehicular actions, or spacewalks, and a smaller robotic arm.
Tianzhou 2 launched in Might 2021 and was the primary customer to the newly-launched Tianhe module. It carried propellant for Tianhe and delivered provides, gear and experiments forward of the Shenzhou 12 crewed mission, which ran from June to September 2021.
It has remained docked to Tianhe for use in checks for shifting future house station modules. The cargo spacecraft shall be deorbited and deplete on reentry as soon as after the checks are full, carrying with it waste materials from Tianhe.
Presently, Tianhe has three spacecraft docked at its ports. Along with Tianzhou 2, the Shenzhou 13 crew capsule is docked on the nadir port, that means it’s pointing down in the direction of Earth, whereas Tianzhou 3, which delivered provides for the three Shenzhou 13 astronauts for his or her six-month-long mission, is docked on the rear port.
Shenzhou 13 is predicted to run till March when astronauts Zhai Zhigang, Wang Yang and Ye Guangfu will return to Earth.
Tianzhou 4 will then launch forward of the Shenzhou 14 mission. That six-month-long crewed mission is predicted to be aboard for the arrival of Mengtian and Wentian later within the yr.
