Xi'an East Railway Station is complete! ready to open with the Xi'an–Shiyan HSL on July 1. The Xi'an–Shiyan HSL is a more direct diagonal HSR trunk line between Xi'an and Wuhan providing relief to the busy Xi'an-Zhengzhou and Wuhan-Zhengzhou HSR. For some reason...

On Nov 8 China launched three Shiyan-32 satellites to a 440 km orbit with an unknown mission. On Dec 18, Shiyan 32-02 (object C) raised its orbit from 421 x 439 km to 444 x 456 km and appears to have released a debris object, cataloged as 67225. I'll have to monitor further to see what's up.

A new element set for Shiyan 29 shows it in a 35796 x 36586 km x 28.5 deg inclined geosync drift orbit. The earlier transfer orbit elset probably belongs to the CZ-3 third stage. I expect the YZ-1 stage to show up in a similar orbit to Shiyan 29.
