China's Space Program News Thread

[Temstar]

I don't think I've seen this posted here, but it could totally be old news.

Space walks are apparently planned for the upcoming Shenzhou missions.

Well yeah, Tianzhou 2 had among its other cargo two EVA suits for this purpose.
Which is a bit interesting actually. Do Shenzhou crews get suited up during launch and reentry? I'm guessing the suits used for inside the capsule are different from EVA suits intended for working outside.

They are different.

The space-X in-capsule suit makes the astronauts look like sanitation workers about to enter a city sewer to clean it.

for some spacecraft, the in-capsule suit would not be capable of keeping the occupant alive in the case of total depressurization. An Soyuz capsule killed 3 cosmonauts when it accidentally depressurized during re-entry.

If I remembered correctly, they did not had their pressure suits on during reentry, as the first-gen pressure suits are too bulky for the tiny Soyuz return capsule.

early space shuttle onboard suits can supply emergency breathing air, but also can’t keep the astronauts alive if cabin pressure drops to zero.

The pressurized suit, worn in the capsule only works to a certain high altitude. The Space-X pressurized suit on the other hand looks to be more capable of handling depressurization of the capsule, maybe possibly to full depressurization.

Hopefully, the taikonauts will reveal themselves in some new in-capsule spacesuits in the coming mission.

Look at the flaring effect of the lander retro rockets (upward and downward) and the dark halo around it on the Martian surface!

This is the first time I've seen such a flaring/halo effect on the Martian surface.

Some of NASA's probes/landers also use retro rockets for landing but as far as I can recall there's no picture from orbit showing the landing site before and after the landing of the lander/probe particularly showing this effect.

着陆平台南北方向，存在对称的喷射状亮条纹，可能是着陆后着陆平台钝化时吹除了较细的尘埃形成。

This is the official interpretation by CNSA. The two strips north and south are probably caused by

. Basically dumping all remaining fuel. The dumped fuel is gaseous and will blow the soil away.

This mark won't last long before being erased by wind and sand. That is probably why you could not find any similar photos from NASA.

Russians talking smack about Chinese tech. I'm shocked! Shocked! Totally shocked, I tell you!

Why do you blame Russians? She is an Ukrainian working for the western countries for all her life. What do you expect her to say anything about China or Russia? Here is the background check of the author Maria Shagina.
