So I'm reading how the US is such a responsible country with space that the US can control the angle of how their junk enters the atmosphere unlike China where it's just hurtling through the atmosphere. I think you would want it hurtling so it breaks up from the stress and burns more throughout.

The CZ-5 is the rocket with the largest "upper stage" that reaches orbit currently in service anywhere in the world right? Ariane 5's is quite a lot smaller? It's an interesting design the CZ-5 has and the volume of space it can be changed to accommodate is impressive and looks like it's been designed specifically to build the space station. If they truly don't have actual de-orbit systems on CZ-5 rocket (assuming it wasn't a failure of the system and they truly just didn't care), maybe the outrage and media hysteria will push them to create one because give it enough launches to build the station, however slim the chances are that the stage smashes into population builds to unacceptable levels eventually. Honestly it shouldn't be that difficult to do.

Are there any other launch systems that leave very significant upper stages in orbit? Do they all have rocket powered de-orbit systems in place?

但微博科普帳號「@北斗_玉衡」當時發文分析,運載火箭的末級火箭本身就會成為不受控的太空垃圾,「沒有人會控制已經無控的太空垃圾使其精確返回」,批評歐美國家藉機炒作事件來抹黑中國。

官媒《環球時報》則引述航天專家、小火箭公眾號創始人邢強博士,指中國運載火箭殘骸的飛行軌跡也並非「不受控」,而是經過科研人員的精密計算,並利用「火箭鈍化技術」,有意縮短在軌飛行時間,殘骸最終會落在南太平洋人跡罕至的「航天器墳場」。

However, the Weibo popular science account "@北斗_玉衡" posted an analysis at the time that the final stage of the carrier rocket itself would become uncontrolled space junk. "No one will control the already uncontrolled space junk and return it accurately. Criticize European and American countries for taking the opportunity to speculate on the incident to demonize China.

The official media "Global Times" quoted aerospace expert and founder of the small rocket public account, Dr. Xing Qiang, saying that the flight trajectory of the wreckage of the Chinese launch vehicle was not "uncontrolled," but was calculated by scientific researchers and used "rockets." Passivation technology" intentionally shortens the flight time in orbit, and the wreckage will eventually fall on the inaccessible "spacecraft cemetery" in the South Pacific.
So that guy was basically making everything up. He didn't even get the ocean right.

It's just unfathomable to face up to the inconvenient truth, isn't it? The re-entry is "under control", but we can't tell you where it's going to happen. LMFAO.

And then we have a small army of Lu Xun's Ah Q men in this forum who rush in to deflect the embarrassment with spins and excuses of their own.
