On October 23 at 19:25 Universal Time, the Mars Long-4B (Y81) launch vehicle launched six Yugan remote sensing satellites into low-Earth orbit from Pad 94 of the Jiuquan Satellite Launch Center. The devices are divided into two groups between the groups "Yogan-53" (07-09) and "Yogan-56" (19-21). The launch complements the teams whose first vehicles (01–03) were deployed in early September. Including this launch, 18 Yaogan satellites were put into orbit in 2026 by six launches, including Yaogan-40 (group 04) and the Yaogan-50 series in retrograde orbit. Given the number of devices, it can be assumed that several more launches will be required for full deployment. The title of the series "Yogan" translates as "remote sensing". Traditionally, Western experts classify these devices as military satellites. The Chinese side, traditionally no less, states that the tasks of these devices include supporting scientific experiments, conducting an inventory of land resources, assessing crops and planning measures to prevent natural disasters. It is interesting to note that the commercial companies MinoSpace and GalaxySpace participated in the development of the satellites, although what their contribution was is not specified. MinoSpace also participated in the development of the payload for the Yeogan-43 satellite group.
