[ Austin x Shiyan - OC Doodle ]

Shiyan definitely underestimated Austin's size. (Whoops forgot to post this here)

Shiyan 28B-02 now tracked by Space Force in a 791 x 797 km x 11.0 deg orbit. The orbit is very similar to that of Shiyan 28B-01, whose orbital plane is 33 deg away from 28B-02's.

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.

CZ-11 reported to have reached orbit with the Shiyan 32-01, 32-02 and 32-03 satellites
LAUNCH at 2100 UTC Nov 8 of a Chang Zheng 11 from the DFHT ship in the Yellow Sea; unknown payload, and still unclear whether or not the launch was successful.

LAUNCH at 0332 UTC Nov 9 of a Lijian-1 from Jiuquan, placing the Chutian-2 Jishu Shiyan 01 and 02 low orbit imaging satellites in orbit.

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.

LAUNCH at 0234 UTC of CZ-3C/YZ-1 from Xichang carrying the Shiyan 29 satellite. Target orbit unknown but likely geotransfer.
