#ChineseRocket Ok I& #39;m gonna put this out because this situation is pretty ridiculous. Yes, China was irresponsible, and their deorbiting system on the Long March 5B failed, as such it& #39;ll do an uncontrolled re-entry. No one talking about this though seems to understand (1/5)
that it will not survive re-entry. The parts that are most likely to survive are the engines at the base of the vehicle and maybe some piping, not most of the 20-ton launch vehicle. The vehicle will enter Earth& #39;s atmosphere at 8 km/s (5 mi/s) and will undergo extreme (2/5)
heat which will violently obliterate all the parts of the rocket which aren& #39;t designed to withstand those extreme temperatures. This isn& #39;t a "China is bad" thing, this is just a spent booster re-entering. No one seems to be complaining about how SLS, an 80-ton booster. (3/5)
every single launch, or how the Space Shuttle did something similar with its external tank. Skylab had an uncontrolled re-entry and weighed over 70 tons, and the S-II stage for that launch orbited Earth for 18 months before re-entering, and that weighed 36 tons. (4/5)
