China's Space Program News Thread

Unlikely. It will take this sail some two years to de-orbit the spent rocket, that’s a long time to be waiting.

I don't think the sail would take that long time to brake the rocket.

Think about the Hall effect thrust devices. They help the position control of the much heavier spacecraft within hours to days. So I think the de-orbiting sail, as it is continuously exposed in the upper atmosphere, would much probably take effect within days to weeks, or several months at most.

It is really necessary. It's hard to imagine how crazy Koreans are about their recent success：Those fanatical South Korean netizens even claimed that China should seek "advanced technological cooperation" with South Koreans.

Considering the increasingly crazy public opinion offensive of extreme nationalists in South Korea, the export of any advanced technology must be cautious.

After blowing up dozens of rockets they finally achieved success so it must be super advanced?

Would it enable second stage reusability?

No. The sail is only to slow the 2nd stage asap to the speed that it can not continue the circulation. It's function is like retro rocket used to actively de-orbit 2nd stages.

This sail alone is not necessarily related to nor meant for re-usability.

Well, I read your question as about that particular sail, not about the general concept coupled with Hall trusters.

Construction of the world's largest circular radio telescope array in southwestern China (on the Tibetan plateau) is expected to be completed by the end of 2022. The Daocheng Solar Radio Telescope (DSRT) will have 313 parabolic antennas – each 6 meters wide – arranged in a circle. The DSRT will be used to study dangerous solar eruptions known as coronal mass ejections

I am no Radio Astronomer, but this seems like it might be capable of more than just studying coronal mass ejections.

A real sick joke, to say the least.
