CZ-8 mission prep. Launch is expected sometime within the next three to four weeks. It will carry a Chinese record of 22 satellites.
Wonder when the recoverable variant would be ready.

Once again it depends on the application and the 3d printing technology
Laser powder bed fusion gives the best resolution and details while currently being limited to about half a meter in diameter and a couple meters in Z. However, EB, or spray system mounted on robotic arms can be much larger at the cost of resolution, however for certain components this is sufficient.
Struts, brackets, combustion chambers, all can and have been 3d printed and used. Space X raptor engines have large amounts of 3d printed parts, same for Chinese startups like Galactic Energy, Deep Blue, as well as the state owned enterprises.
It might take longer than we thought. In Long Lehao's PPT. It was said at end of 2023. But based on the newest info. The regular version of CZ-8 may launch only one in whole 2022(27 Feb), plan to launch 8 in 2023. So I think the recoverable one would take longer to develop.
Wut... First person to play Guzheng in space.
Interesting that they did not bother to paint the variant designation. The earlier interview did not say variant designation either.CZ-8 mission prep. Launch is expected sometime within the next three to four weeks. It will carry a Chinese record of 22 satellites.
In today's CCTV 19:00 news program
There is a section about Xi Jinping's tour of space industry. Here is the text version of the report
In it, it says that development work of Heavy lifter (CZ-9) and CZ-5DY has already began. The significance of this report is that it is engineering work after subsystem breakthrough and pre-study/feasibility study.
牢记总书记嘱托，新的一年，中国航天正一步一个脚印开启太空探索新征程。
在天津，新一代运载火箭长征五号、长征七号整装待发。在海南文昌，长征八号遥二运载火箭即将执行一箭22星的发射任务。今年，中国航天的发射次数将保持50次以上的高密度。面向未来更深更远的太空，载重量超过100吨的重型火箭、新一代载人火箭也已经进入研制阶段。

I wonder how microgravity environment impacts the playing.
