A review of domestic commercial SAR satellite technology and application status.

Active commercial SAR satellites include:
1) Tianyi C-SAR satellite Haisi-1 and Chaohu-1 (天仪C-SAR卫星海丝一号、巢湖一号);
2) Zhongke Qilu-1 Ku-SAR satellite (中科齐鲁一号Ku-SAR卫星);
3) Taijing-4 (泰景四号X-SAR卫星);
4) Four InSAR satellites of Aerospace Hongtu-1 Group 01 (航天宏图一号01组InSAR四星);
5) Twin X-SAR satellites of Gaojing-2 (高景二号X-SAR双星).

All of the above listed satellites are capable of resolutions of ≤1 meter.

Fucheng-1 (涪城一号), the first satellite of the Mianyang remote-sensing constellation (绵阳星座) has been delivered to Jiuquan launch center, with the launch scheduled for May, 2023.

observation satellite developed by Changsha Tianyi Space Technology Research Institute (长沙天仪空间科技研究院). It weighs 300kg and has a maximum resolution of 1m by 0.5m. By 2025, the Mianyang constellation will consist of six SAR satellites. All satellites of the constellation will be produced at the Fucheng satellite production base, which currently has an annual production capacity of six satellites, set to increase to 20 per year by 2024.

A research facility for space farming.

The facility is too huge for space study, and there is nowhere to see that it is specially used for space farm research. Perhaps an organic soil matrix and a special nutrient solution distribution system packaged to prevent scatter in microgravity? Or are the seeds treated with space breeding technology used for trial cultivation?

Sorry, my knowledge on horticulture is far below the minimum required to understand your post.

P.S. I'm pretty sure I can't even keep a cactus alive.

(ECNS) -- China's space station Tiangong can achieve 100 percent production of its oxygen resources through an onboard regeneration system, according to a conference on manned space environment control and lift support technology held in Harbin, northeast China's Heilongjiang Province.
Over the past 55 years, experts at the China Astronaut Research and Training Center have successfully developed three generations of environmental control and life-support system for China's manned spacecraft, as well as relevant products for 15 Shenzhou spacecraft, five Tianzhou spacecraft, two Tiangong target spacecraft, five sets of Feitian extravehicular spacesuits, as well as environmental control and lifesupport systems for the combination of the Wentian and Mengtian lab modules with Tiangong space station.
The expert team has overcome world technical challenges such as oxygen production by water electrolysis, carbon dioxide removal, harmful gas removal, urine treatment, water treatment, and water production with carbon dioxide and hydrogen.
The environmental control and life-support system has created basic living conditions and built a livable working environment for the astronauts in the closed environment of space, ensuring their health and safety. They are known as a "protective umbrella" for the astronauts.
The systems have realized the fundamental transformation from "replenishment" to "regeneration," making outstanding contributions to the construction of China's space station.
"One of our very important tasks in orbit is to maintain the environmental control and life support systems, especially the stable operation of the regenerative life support systems, which allow us to breathe fresh oxygen and drink sufficient water in space, said Astronaut Cai Xuzhe from the Shenzhou-14 mission.

I'm most interested in learning how bees fly in space.

I guess it could be testing systems for a future moon/Mars base as opposed to microgravity space.
