CASC has successfully completed China's 1st on-orbit demonstration/experiments of Stirling converter that generates electricity efficiently from heat, a key technology that will play important roles in future crewed lunar missions & deep space explorations
Few details does not equal "secret".
I would be extremely disappointed with the Chinese if they simply jettisoned their trash into open space.EXTREMELY disappointed!
CMSA released a 25s footage of Shenzhou-15's 3rd spacewalk.@mickeywzx, more material to figure out the timestamp?

They have a very capable ship, but that means it's not as easily disposable as Progresses might have been in the past, which is what basically supported frequent and abundant trash disposal in long-duration space stations until now.Certain amounts of trash jettison was common practice in mostly every space station before ISS (not justifying it as good practice, just noting how it was arranged until not very long ago). In fact, unneeded bulky items are regularly jettisoned from ISS both from the USOS and the ROS: an old Orlan filled with waste, external payloads of all kinds, including a ROSA, several experiment packages, MLI bundles, an HTV EP... Good thing about reasonable amounts of crew waste in human-tended LEO is that they have a pretty favorable ballistic coefficient for quick deorbit, and will completely burn up/sublimate away once it does, posing literally no ground hazard.And again, these are some rumors that were published online - most likely the real reason for the spacewalk was not just "taking out the trash", and if it indeed happened was just a task of opportunity for some particularly cumbersome items.

Old MMOD blankets, thermal covers, broken equipment, and other small items have been "tossed overboard" by spacewalking astronauts. The Roll Out Solar Panel test article was also ejected from the ISS after the deployment tests were completed.

I had no idea because the returning cargo spacecraft was always carrying a full load of trash for disposal. Shuttle did it, Soyuz did/does it and I've been assuming that Dragon did/does it. Disappointed.
Hey guys. Taikonaut #YeGuangfu says welcome to China Space Station. Here comes my 1/4 of exclusive interview with Taikonaut Ye Guangfu of Shenzhou 13 manned mission. He spent 183 days in China's Space Station from Oct 2021 to April 2022. How is his training right now? Take a look
There are countless unforgettable moments during #Shenzhou13 crew‘s 183 days staying aboard China Space Station. For taikonaut Ye Guangfu, the most impressive one was his first spacewalk. He described what he had seen, felt and thought to me.#HumanSpaceFlightDay
👀 New episode: @TiangongStation China Space Station needs more storage!
Beautiful view of Earth through the porthole though, passing over Taklamakan Desert and Tibetan Plateau
