Past the moon, while DSCOVR was in another part of the sky. It would be a little strange if the second stage went right That the DSCOVR spacecraft's trajectory did not go particularly close to 'DSCOVR (and this rocket stage with it) passed close by the moon on 2015įebruary 13, two days after it was launched. Lot of active spacecraft, including DSCOVR. JPL doesn't track space junk, but they do keep careful track of a This morning (2022 Feb 12), I received an e-mail from Jon Giorgini So if this isn't the SpaceX booster you thought.Plans to start tracking cislunar objects? Perhaps by an 'official' agency of some sort? Should high-flying space junk be better tracked?.How did this mistake get past everybody? Aren't others.But Space-Track/18SPCS says the Chang'e 5-T1īooster hit the earth's atmosphere long ago!.Why did China's Foreign Ministry say this isn't the Chang'e 5 booster?.Why I'm now sure it's actually the Chang'e 5-T1 booster.How the object was originally (mis)identified as the.Moon within a few kilometers of the predicted spot on 2022 March 4 atġ2:25 UTC, within a few seconds of the predicted time. That it is actually 2014-065B, the booster for the The second stage of the DSCOVR spacecraft. I (mis)identified this object as 2015-007B, Note : I keep getting questions that cause me to realize I shouldĮxplain something else, or that I explained something poorly. Corrected identification of object about to hit the moon Corrected identification of object about to hit the moon UPDATE : resulting impact crater has been imaged

What happend to the moon on march 4th
