Is there a misunderstanding? It could be that your colleague meant that Tianzhou-3 will conduct a test dock by the robotic arm on Tianhe, not itself carrying a new robotic arm.

There seems to be no mounting port for robotic arm on Tianzhou. The plan was to have one of the lab modules carrying another arm.
Could be the case, he himself heard it from another department

Rumour from colleague,Tianzhou 3 has a robotic arm
Well there is something you see sticking out in the shadows as the module is coming in to dock on the lower left of the the Tianzhou 3 that couldn't have been there while being launched. So something like an arm was extended out after it reached its orbit.

Are you sure you are looking at Tianzhou 3 instead of Tianhe? On the lower left side of Tianhe in the shadow is the robotic arm.

Or are you talking about these protrusions? They are thrusters and some sensors for docking. They are within the envelope of Tianzhou-3's diameter.

The landing accuracy of Shenzhou-13 is very impressive.

  1. The helicopter was overhead when Shenzhou-13 touched down. Meaning the last prediction (4th) is very accurate.
  2. The landing range was set in a 3.6km by 3.6km square.
  3. The 1st prediction was "100 04 46 E, 41 37 23 N". It was made just after seperation of capsule and propulsion module while at altitude between 100km and 140km.
  4. The 4th (last) prediction was "100 04 34 E, 41 37 23 N". It was made when the capsule altitude was few hundred meters. At this moment it is only 280 meters from the theorotical landing point (1st prediction?).
We can see from the screen capture how close it is. I guess the final touch down point is around 200 meters to the 1st prediction.

In comparison, I watched SpaceX's landing on May 2nd. The touch down point was 4.6 nautical miles (8.52km) in range (from the target/prediction).

The local weathers are equally calm.
