Not identified yet.) Why I'm now sure it's actually the Identifications of high-flying space junk oftenĪ couple of unidentified bits of junk out there. The brightness we would expect, and had showed up at the expected timeĮssentially, I had pretty good circumstantial evidence for the Identification with the second stage as correct. Two days after DSCOVR's launch, and I and others came to accept the Problems finding any data on DSCOVR's trajectory.įurther data confirmed that yes, WE0913A had gone past the moon Or some bit of hardware associated with it, but that I was having The sun, suggesting it might be a human-made object.Ĭonfirm this, and wrote that I thought it was either DSCOVR Noted on a newsgroup that the object was orbiting the earth, not These data are publicly available, and shortly thereafter, Rock, gave it the temporary name WE0913A. "Hmmm, can't find that one." The discoverers, thinking they had a Them as well and say "I found it, too, at the following location" or Post data about objects they've found that might be near-earthĪsteroids or comets the idea is that others can then try to observe On 2015 March 14, about a month after DSCOVR was launched, theįound a possible near-earth asteroid. (mis)identified as the DSCOVR second stage I did that digging in fullĬonfidence it would prove that the object was, in fact, the DSCOVR Myself why I had originally identified the object as the DSCOVR stage Prompted by Jon's e-mail, I dug into my e-mail archives to remind
There'sĪlways some separation, but this was suspiciously large. 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.
#WHAT HAPPEND TO THE MOON ON MARCH 4TH UPDATE#
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
