and presumably one of those may be the 2nd stage body that will or won't fall back to Earth soon in a controlled or uncontrolled way.

But there's no 2021-046A currently, and according to Space News' Tianzhou-2 docks with China’s space station module... Tianhe (which) paves way for June crewed mission. it docked with Tianhe (2021-035A, 48274) about 8 hours after launch.

Question(s):

1. Did Tianzhou-2 have a TLE before docking with Tianhe 8 hours after launch?
2. What object is the 2nd stage rocket body and roughly how soon will it reenter?
