Rocket stage to hit Moon is from Chinese rocket, not Falcon 9 upper stage
Astronomers have now concluded that the rocket stage that will impact the Moon on March 4th is not an abandoned the Falcon 9 upper stage that launched the DISCOVR satellite in 2015, but an upper stage from a Chinese rocket.
It was an engineer at NASA’s Jet Propulsion Laboratory, Jon Giorgini, who realized this object was not in fact the upper stage of a Falcon 9 rocket. He wrote to Gray on Saturday morning explaining that the DSCOVR spacecraft’s trajectory did not go particularly close to the Moon, and that it would therefore be a little strange if the second stage strayed close enough to strike it. This prompted Gray to dig back into his data, and identify other potential candidates.
He soon found one—the Chinese Chang’e 5-T1 mission launched in October 2014 on a Long March 3C rocket. This lunar mission sent a small spacecraft to the Moon as a precursor test for an eventual lunar sample return mission. The launch time and lunar trajectory are almost an exact match for the orbit of the object that will hit the Moon in March.
Regardless, it will be very useful to pindown the exact impact time and place so that astronomers can observe it.
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 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

Man, will this infuriate the Musk haters, who’ve been after him for allowing such a thing to happen. Of course. the Chinese Ministry of Public Enlightenment will be working overtime – I can see steam pouring out of ears – to convince the world this is a lie concocted in the Fascist US to cover for a running dog capitalist swine,
I’m kind of disappointed…it would have been SpaceX’s first contact with Luna.

James Street – Three cheers and a Tiger!! It’s a national disgrace we’re there at all for Munich-36 2.0 – guess we didn’t learn our lesson. As for the athletes, plenty of them are willing to criticize the US for our failings – which are miniscule compared to Xi’s paradise – , what are they doing in China?
