Abstract
The Higher Plant Culture Device (HPCD) and the Animal Embryo Culture Device (AECD) were developed for life science experiments on board of the SJ-8 satellite and are discussed in the present paper. System composition modes and key technologies are described in detail, i.e. the photomicroscope with self-focus algorithm, the optical imaging path and the flexible positioning method of flowers, the special-purpose embryo vessel for culture and observation with lighting, in total four representative and innovative items of the key technology. Results and shortages of this space experiment are discussed briefly demonstrating that facilities work well in the microgravity environment. Finally, future improving principles are proposed.
