A classified Chinese know-how verification satellite that introduced previously this month has apparently unveiled an item into orbit together with it.
China released (opens in new tab) Shijian 23 on a Extensive March 7A rocket on Jan. 8, sending the satellite into an first transfer orbit to get to its meant geostationary orbit (GEO), all over 22,236 miles (35,786 kilometers) over Earth.
Info produced by the U.S. Room Pressure‘s 18th Area Protection Squadron (18 SDS), which focuses on area domain consciousness, reveals that Shijian 23 reached geosynchronous orbit all over Jan. 15, drifting toward its supposed posture in the GEO belt. Cataloging by the 18 SDS has even more revealed that Shijian 23 released an object on Jan. 16.

The Shi Jian 23 experimental satellite arrived at geostationary drift orbit all around Jan 15, and at about 2100 UTC Jan 16 it produced a subsatellite, cataloged now as 55180 / 2023-002CJanuary 20, 2023
18 SDS lists the item as an “AKM” or apogee kick motor, which is applied in some launches to assistance a satellite get to its spot orbit. Even so, it is achievable that the object is a subsatellite, possibly to be utilised with each other with the mum or dad satellite for on-orbit screening.
China’s Shijian 21 satellite, which released in 2021, also attained GEO and unveiled a satellite, which was then applied for checks. Shijian 21 then proceeded to dock (opens in new tab) with the defunct Chinese navigation and positioning satellite Beidou-2 G2 and towed it away to an orbit out of the way of the lively spacecraft in GEO.
The geostationary belt is really valuable for a variety of purposes, as satellites orbiting there go in sync with Earth’s rotation, making them surface fastened in the sky more than the earth. This orbit is as a result really helpful for offering regular communications, meteorological information and surveillance about preferred locations. Eradicating useless satellites and debris from this belt will assist to maintain the orbit available for use.
What China has prepared for Shijian 23 has not been uncovered, however. The satellite was explained tersely as “mostly applied for scientific experiments and technical verification” by Chinese state media. Ongoing monitoring may well deliver clues to the activities of the satellites.
More complicating issues is the simple fact that original reviews soon after launch from equally China’s principal house contractor and condition media Xinhua shown two additional satellites (opens in new tab), Shiyan 22A and 22B, as payloads aboard the launch. An up to date tale (opens in new tab) from Xinhua a working day later omitted reference to the latter pair.
