Did pieces of a Chinese upper stage land in middle of Mediterranean last week?
According to a tweet from a Twitter account that specializes in reporting on the Chinese space program, at least one piece of the upper stage from the Long March 2F rocket that launched the present Tiangon space station crew on the Shenzhou-14 crashed into the middle of Mediterranean Sea when the stage’s orbit decayed.
Most parts burned during the reentry while small debris splashed in Mediterranean Sea around E5.2° N39.1°
According to both this Twitter site as well as the Aerospace Corporation’s re-entry site, the event occurred on June 20, 2022. The latter site however says the stage burned up over the Atlantic, though it also indicated a one hour margin of error both before or after that time. If the stage thus stayed up just a bit longer, its orbit would have brought it down exactly where the former site states.
If this is so, it indicates that the Chinese either could not or made no effort to control the de-orbit, something that should be standard for any upper stage that has mass that could hit the ground.

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

You know, at this point in the orbital launcher development game, I’m wondering if the Chinese ‘failure’ to control orbital debris, is. The Mediterranean is a smaller target than the Atlantic or Pacific. Then there are the Moon impactors with new configurations.
The tech to control upper stage de-orbit has been around for a while, and the Chinese are as capable as anybody. As the Western world moves toward more efficient practices, the Chinese act like they don’t care. As Chinese space launch practice becomes more incongruent with General Accepted Aerospace Principles, you have to ask, why?
