An astronomer who claimed a piece of one of Elon Musk’s Falcon 9 booster rockets was going to slam into the moon in March has admitted making a mistake — he now says the hunk of space junk belongs to a Chinese rocket.
Bill Gray set the astronomy world abuzz when he made a very specific prediction about a moon impact on March 4, 2022.
While Gray has slightly tweaked his calculations to put the impact a few kilometers away from the original impact spot, he now thinks the “long cylinder, spinning slowly” is not part of a Space Exploration Technologies Corp. booster, but belongs to a Chinese rocket sent to the moon in October 2014.
In an amended blog post at the weekend, Gray, of Project Pluto, which supplies software to amateur and professional astronomers, wrote: “We now know that this object is not actually the SpaceX booster: that was a misidentification, by me.”
And in a fresh post entitled “Corrected identification of object about to hit the moon,” he wrote: “Back in March 2015, I (mis)identified this object as 2015-007B, the second stage of the DSCOVR spacecraft. We now have good evidence that it is actually 2014-065B, the booster for the Chang'e 5-T1 lunar mission. (It will, however, still hit the moon within a few kilometers of the predicted spot on 2022 March 4 at 12:25 UTC, within a few seconds of the predicted time.)”
So if it isn’t a part of Elon’s rocket, where did that end up?

Gray said his best guess is that the booster followed the DSCVR weather satellite launched by the Falcon 9 on its million-mile journey into deep space, and is now probably in an orbit around the sun.
