China's Space Program News Thread

One thing worth noticing is that CZ-5 core stage is actively de-orbited according to CCTV-13's guests. Unlike many western propagandist "professionals'" claim that CZ-5's core stage passively enter atmosphere without any knowledge of when and where it will land.

Another thing about CZ-5B is that it is the only operational one stage launcher. Note, boosters are counted as 0.5 stage, core stage is the first. Its closest counterpart is space-shuttle, whose main engine and ET make up the core/first stage. However, shuttle drops most of its first stage (ET) before reaching orbital velocity, orbit insertion is done by OMS onboard the shuttle.

This is what happen on the first launch of LM-5B. Debris from core stage fall on a village in Ivory Coast west africa

It is the Rube Goldberg way to get into space.

It is much, much easier to make a two stage VTVL vehicle for space launch. And you will have a lot more payload.

But considering the time period it was proposed - XB-70, Concorde , Space Shuttle, an-225..
It would've made a lot of sense then.
A Rube Goldberg contraption only when considered today (with vtvl solutions existing).

Lmao another propaganda outlet from UK, the Guardian. Look (or hear..) how they reported on the new space station launch by China

Lots of static noise there..

Looks like scam photos. Do the math on the potential and kinetic energy of a piece of metal weighing 100+ kg and falling from hundreds of kms, that tree would be vaporized! What you see if a tree not harmed at all, maybe it's grown with tungsten, stronger than the rocket piece.

Also one photo is a pipe, the other is a flat piece curved up, so not even the same thing.

National Post is as bad as national interest, it's a troll paper.

I think also the first to use soft solar panel, few months before ISS (yet to be launched).

Didn't they test one out on ISS back in 2017? Though that's not a permanent add-on.

That is why I do not count it because it is not in the working condition to actually providing electricity to ISS operation. That is also why I said few months before ISS to install the working one some time in 2021.

And what is your point? What does what you are saying have anything to do with "active de-orbiting" anyway?

This is what happened to the second stage of Falcon 9 (the almighty god like SpaceX) after launch on March 25 2021, it fell on a farm in Washington state.

Imagine a person standing in the middle of this spot?

I did not investigate the claim of the found debris in Ivory Coast is from CZ-5, neither am I going to reject the claim without investigation.

But from the perspective of evidence gathering and analysis, you are not providing anything to support that claim. All I see are:

1. A pipe of 15cm in diameter (in reference of the bystander's leg).
2. The fairing on the side of CZ-5 that encases a pipe in the similar diameter.
3. A photo and a video showing a curved casing of about 50cm wide.

I see the way that you are trying to prove your point was to make the red arrow pointing at the fairing of CZ-5. But that proves nothing because all rockets (at least all cryogenic) have that piping and casing.

The right way to support your point is to present:

1. The launch date of the rocket.
2. The launching direction of the rocket.
3. The atmospheric entry point and time of the first stage.
4. The entry velocity.

Combination of some of them (not necessarily all) would be enough. All these information are available.
