China’s X-37B releases object in orbit

China’s copy of the U.S.’s military’s X-37B reusable mini-shuttle, dubbed Shenlong apparently released an object during its ongoing third orbital mission.

A new object (59884/2023-195G) has been cataloged associated with the Chinese CSSHQ spaceplane in a 602 x 608 km x 50.0 deg orbit. It seems to have been ejected about 1900 UTC May 24.

It is possibly this object is to test recapture maneuvers, as was done by during the mini-shuttle’s previous flight. It is also possible this release is preliminary to the end of the mission and the return of Shenlong to Earth. It is also possible it has a completely different purpose, since China has released practically no information about this spaceplane or any of its missions.

The present mission began a little more than seven months ago, releasing six small satellites a few days after launch. The previous two lasted two days and 276 days respectively. As with everything else, we have no idea how much longer it will remain in orbit.
