Banxing or BX-1 (Chinese: 伴星; lit.: 'Companion Satellite'),[1] is a small Chinese technology development satellite which was deployed from the Shenzhou 7 spacecraft at 11:27 GMT on 27 September 2008.[1] Prior to deployment, the satellite was mounted on top of the Shenzhou 7 orbital module.

Purpose

Banxing was used to relay images of the Shenzhou 7 spacecraft.[2] Weighing some 40 kilograms, and containing two cameras and communication equipment, it was maneuvered using an ammonia gas-based propulsion system.[3] Following the re-entry of Shenzhou 7, Banxing remained in orbit as part of a formation-flying experiment with the discarded Shenzhou orbital module.[4]

A few hours after Banxing was launched it and the Shenzhou 7 orbital module passed unusually close to the International Space Station. This provoked some speculation that the experiment was intended to test military anti-satellite interception technology.[3]

gollark: Random *public* service, obviously. I use it for potatOS.
