I picked up an insider rumor that a 4th EVA by the Shenzhou 15 crew will be held/might be underway today. IIRC official reports after the 3rd EVA did state that there are still more planned before the crew returns to Earth so this would not be surprising.

More rumors of this EVA (which is apparently underway or already completed): Deng Qingming was originally scheduled to be one of the spacewalkers but was ultimately replaced (i.e. Fei Junlong & Zhang Lu went out).

CMSA confirms the 4th EVA of Shenzhou-15 mission took place yesterday, April 15. Astronauts Fei Junlong & Zhang Lu outside, Deng Qingming supporting from Tiangong. Combined robotic arms transferred the astros from wentian hatch to Mengtian payload hatch. mp.weixin.qq.com/s/OtzNED9d253L…

CMSA's steps to relocate Tianhe's solar arrays:
1️⃣ fold the flexible solar array back
2️⃣ astronauts remove 12 fasteners & 8 electrical connectors
3️⃣ robotic arm move the folded solar arrays to lab modules' ends
4️⃣ astronauts install controllers and connectors
5️⃣ re-deployment

China has completed in-orbit experiments on liquid metal thermal management on its space station for the first time. The device, mounted on the country's space lab module Mengtian, is one of the space station's first five experiments on space technology http://xhtxs.cn/HHA

😮Here’s how equipment inside is moved outside of Tiangong Space Station (CSS): load on trail -> remotely slide to airlock -> depressurize -> open latch -> robotic arm pick up -> remote mounting. Whole process does not need astronauts’ EVA spacewalk. Full: buff.ly/43c7294

I believe this is also the first view of (actual operational hardware of) the Chinese native design of grapple fixture - i.e. not the Latching-End-Effector-like main arm manipulator or the Lyappa-like indexing arm. See attached PDF.

China wants commercial resupply to their station at $17.2 million/metric ton!

3 month docking, 7 cubic meter 1.8 metric ton up, controlled disposal reentry with 2 metric ton of trash is the requirement

Why and how did #Tianzhou5 re-dock with the #ChinaSpaceStation？
Tianzhou-5 separated from #ChinaSpaceStation in May to leave room for #Tianzhou6.
Now #Shenzhou15 had gone, Tianzhou-5 re-docked with the station to offer room for #Shenzhou16 crew to restore their waste.
