Nothing surprising at all, many if not all engineers of these "private" companies are former employees with years of experience from CASC institutions. What landspace is developing is likely a copy of Xi'an's 200t FFSC. Copy here means the idea and architect (years of research) is the same, not the exact realization.

“SeeSeePee has started ripping off their own tech as they run out of Western ideas to copy” — CNN.

looks like they just did a satellite launch for Egypt (Horus-2), after horus-1 was just launched 17 days ago

在载人航天工程项目支持下,国家天文台宇宙大尺度结构与巡天研究团组成功研制9k×9k全帧转移CCD天文相机,于2023年2月12日至17日联合CSST科学数据处理系统共同在兴隆观测基地80cm望远镜上开展了试观测。这是国内首次基于9k×9k全帧转移CCD的天文观测。

通过本次观测,团队获得了若干标准星、星团和星系的g波段图像以及相应的本底、暗场和天空平场。图1展示了进口CCD观测的NGC3631图像。受望远镜视场和滤光片尺寸限制,实际只使用了靶面中心区域。图2展示了M38疏散星团的g波段图像,为国产CCD拍摄。

本次观测验证了我台自研的多通道、大靶面CCD相机的性能,同时也为CSST科学数据处理系统提供了实测数据,将为后续相机和国产CCD的改进提供依据...

With cooperation from the manned spaceflight engineering project, the large-scale structure of the universe and the sky survey research group of the National Astronomical Observatory successfully developed the 9k×9k full-frame transfer CCD astronomical camera, together with the CSST scientific data processing system, carried out trial observations on the 80cm telescope at the Xinglong Observation Base from February 12 to 17, 2023. This is the first domestic astronomical observation based on a 9k×9k full-frame transfer CCD.

Through this observation, the team obtained g-band images of several standard stars, star clusters and galaxies, as well as the corresponding background, dark field and sky flat field. Figure 1 shows the image of NGC3631 observed by imported CCD. Limited by the field of view of the telescope and the size of the filter, only the central area of the target surface is actually used. Figure 2 shows the g-band image of the M38 open star cluster, which was taken by a domestic CCD.

This observation verified the performance of the domestic multi-channel, large-target CCD camera and also provided actual measurement data for the CSST scientific data processing system, which will provide a basis for the improvement of subsequent cameras and domestic CCDs...

, where they can apply for data and samples, according to the China National Space Administration.
The Chang'e-5 probe, which returned to Earth on Dec. 17, 2020, retrieved a total of 1,731 grams of lunar samples, mainly rocks and soil from the lunar surface.

Please don't just link to a tweet. It's lazy, and it lowers the quality of this forum. Say something about the tweet, summarize it, and upload the photos contained in the tweet separately so that we don't lose them when the tweets go down. Also, the search function of this forum doesn't index linked tweets, so it's extremely important give at least a brief summary so your post shows up in a search. Thank you.
