Re: Four identical high pressure cylinders found in central Argentina

Looking for candidates based solely in the orbital inclination, and being close to re-entry, this candidate came up

CZ-2C  R/B, NORAD 43031, 2017-075D

Inclination is 35.21deg

Space track gives reentry at 2025 Apr 10, 22:12:00UT +/- 1min at

Lat -31.4, Long 56.8W

which is very close to where the pressure cylinders were found. I have no idea if what was found is consistent with a CZ-2C R/B.

Cheers, Rob
