"Designing objects to disintegrate upon atmospheric re-entry is becoming a priority for satellite operators. It's done partly by using materials which have low-melting point temperatures, such as aluminium.

In the case of rockets, this can be expensive, as historically the materials used for housing fuel, such as titanium, require very high temperatures to burn up. The sheer size of such objects is also an issue, especially in the case of the Long March 5, weighing over 25 tonnes."

Expensive?

I think they mean expensive, like the aluminum-lithium alloys used on later Space Shuttle external tanks, and similar structures. Fancy alloys are generally not easy to make or work with, increasing general cost.

The small 5-metre-long robotic arm on Wentian has passed on-orbit testing. Will next connect with the 10m arm on Tianhe for further testing, CMSA says. Some great views in the video below. Source [CMSA]: m.weibo.cn/detail/4798304

The small robotic arm on Wentian has passed necessary tests. Next, it will be connected with the big arm on Tianhe for more tests. As shown in the animation below, the combined arm is long enough to reach the new airlock section from Tianhe. Looking forward to seeing it!

Wentian is not only a laboratory, but also an additional living room for #Tiangong astronauts..

Shenzhou-14 astronauts installing the control moment gyroscope delivered by Tianzhou-4 on Wentian Laboratory Module. 4 of these were already installed on Wentian before launch, and one more will be delivered by Tianzhou-5. In total, 6 CMGs, same as Tianhe, will be on Wentian..

Capture of Wentian module equipment:

This is CHAL 9001 (Chinese Heuristically programmed ALgorithmic Computer)

- CHAL, open the pod bay!
- I'm sorry I can`t do this, Mr. Zhong...




Sorry, I couldn't resist the bad joke... :-[

Emblems of the 3 remaining missions: Mengtian, Tianzhou-5 and Shenzhou-15, to #Tiangong in 2022, released by CMSA but deleted shortly afterwards because there were major errors in the latter two. Try if you can locate the errors.

Next spacewalk on #Tiangong is coming soon.

Red-stripped space suit vs gold-stripped space suit.

If Mengtian is lost in a launch failure, are they able to maintain the Tiangong station with just one experimental module (Wentian, in this case)?

I believe there are backup modules for each section, which is why there talks of phase 2 where the backup modules are used as expansion of the current station.

Breathable and flexible like socks; protective like shoes. That is the intravehicular footwear for Shenzhou astronauts.
The bottom pattern derives from Chinese characters "九天揽月(catch the moon)" in Zuan style. The surrounding holes symbolize stars
