Long March 5B booster reentry prediction narrows again
The Aerospace Corporation has once again narrowed the reentry window for the 21-ton core stage of China’s Long March 5B rocket, launched on April 29th, as shown by the map above. The window is now only eleven hours long, centered over a point in the Indian Ocean at just before midnight on May 8th. The yellow tracks indicate its path after that centerpoint, while the blue lines show its path prior to it. Tick marks show five minute intervals.
The last orbit as shown by this prediction puts it over the following land areas. If the core stage crashes 5 to 20 minutes early, it would land anywhere from Spain to Africa. Another fifteen minutes earlier and Florida and Mexico would be in the landing zone. If it lands 45 to 50 minutes later, it will land somewhere on the continental United States.
China however might be lucky with this booster. The centerpoint of the prediction has definitely begun to stabilize around the Indian Ocean.
With future boosters, who knows? China plans at least three more Long March 5B launches, two in ’22 to launch modules for its space station, and one in ’24 to launch a Hubble-class space telescope to fly in formation with that space station. We shall see this same Keystone cop charade on all three flights, with the core stage tumbling out-of-control and falling back to Earth to crash somewhere that cannot be predicted.
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.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I hope there are some photographers in the Seychelles with their cameras ready. Should make for some great video.
They tried that with Mir-but a chase plane miss when Progress burned to depletion…dropping it short.

“It is the first Chinese launch vehicle designed to use exclusively non-hypergolic liquid propellants.”
So they claim…..what about thrusters….not to worry, there aren’t any
At 2200 Eastern DST it is T minus 58 to impact -predicted for eastern Atlantic, but Ireland, England France, Portugal and Morocco remain possibilities

I give up clock shows 0-00-00 to impact and an altitude of 172 km…..
Down over Arabian peninsula at last report..
