China has conducted a successful transposition test of its space station's cargo craft Tianzhou-2 using home-developed robotic arm early Thursday morning.
It was the first time the robotic arm operated a large space vehicle for relocation, which verified the feasibility and effectiveness of such a maneuver, China Manned Space Agency (CMSA) said on Thursday.
The transposition process took 47 minutes. After grabbing the Tianzhou-2 cargo spaceship that detached from the Tianhe core cabin at 6:12 am, the robotic arm steadily moved the craft in a counterclockwise plane direction until it eventually docked again with the core module and completed locking.
The Thursday test has preliminarily validated the feasibility and effectiveness of the robotic arm's transposition capability, verified relevant technologies, and laid a solid foundation for the busy schedules of space station construction in the new year.
China eyes 40-plus launch missions in 2022, which will include six major space-station-bound flights - two cargo ships, two manned ships and two experimental modules -- the state-owned space giant China Aerospace Science and Technology Corporation (CASC) said on Tuesday.
They will conduct in-orbit rendezvous and docking operations, space walks, and spacecraft returning missions this year, wrapping up the construction work of China's Tiangong space station.
China scored 55 orbital launches in super 2021, topping the US to become the first in the world.
Of the 55 orbital launches, 48 were from the CASC and all of them were successful, sending more than 100 spacecraft into space, and bringing a complete victory to the most ambitious aerospace year of China.
The world saw a total of 145 space launches in 2021, of which 55 were from China, 51 from the US, and 25 from Russia.
China's first ever shifting of Large Cargo SpaceCraft using Robotic arms aboard the Space Station is a success.
On January 6, according to China Manned Space Engineering Office, 6:59 Beijing time, after about 47 minutes of cross-system close coordination, the space station robotic arm transposition cargo spacecraft test was successfully completed.
In the early morning of January 6, the robotic arm successfully captured the Tianzhou-2 cargo spacecraft. The indexing test started at 6:12. After the Tianzhou-2 cargo spacecraft was unlocked and separated from the core cabin of Tianhe, it was moved by the robotic arm to perform the plane indexing with the center of the core module; then the reverse operation was conducted until the cargo spacecraft and the core compartment are docked again and locked.
This test tested the feasibility and effectiveness of using the robotic arm of the space station section transposition that would see increased usage for later operations.

How much of the mass launch in the commercial sector is for Starlink space junk? What the hell is even Spaceship?

General
A milestone. As of January 6th, 2022, the Yutu-2 lunar rover has travelled 1003.9 meters.
It has gotten closer to the mysterious spotted in early December of 2021. It turns out to be a large rock on the edge of a crater. The rover will next perform a close examination of the rock and the impact crater behind it.

So China is launching vastly more in tonnage than the US, even more than the moderately higher gross orbital launch attempts indicate, with one big exception... The US launches hundreds of tons of Starlink satellites. 19 launches in 2021 and each one averaged a payload of 13 to 15 tons. So B (Business/Commercial) is close to 100% just Starlink junk for high latency internet for rural areas.
As for SS (Spaceship) what does that even mean. It's the only other area where China is a laggard, but it still launched two thirds of the US total so not bad.
As for the rest, China launched 8x as much in academic/nonprofit tonnage, almost 4x as much in civil tonnage, and almost 2x as much in defense payload (!).
I suspect some of what is classified as civil under China would have been classified as commercial in the U.S. For example I suspect navigation satellites would have been classified as commercial in the US but civil in China.
