A piece of human - madespace junkslammed into the far side of the moon last year , initially leaving scientists stumped . After some galactic tec work , new research argue that it was most likely a Chinese booster skyrocket – with an obscure object sequester to it .
On March 4 , 2022 , a cryptical object known as WE0913A crashed into the lunar surface , leaving behind anunusually shaped dual - volcanic crater . While it was initially suspect to be part of a SpaceX Falcon 9 rocket , later evidence suggested it was a booster as part of the Chang’e 5 - T1 lunar mission . China , however , deniedany involvement .
Now , scientists at the University of Arizona , California Institute of Technology , Project Pluto , and the Planetary Science Institute go for to put the mystery to bed .

They map the target ’s flight using ground - free-base telescope observations and conclude that WE0913A is part of a Chinese Long March rocket eubstance from the Chang’e 5 - T1 foreign mission that launch in 2014 .
On top of this , they also found grounds that the abandoned garden rocket point belike carried an “ undisclosed , additional payload . ”
The team made this claim with two line of grounds . foremost , the aim did not appear to careen as it fell to the lunar airfoil , but rotated in a passably unionise roll spill . They argue that this shows that the rocket stage was balanced out with a significantly sized counterweight to the two engine , each of which weighs 544 kilo ( 1,200 pound ) .
" Something that ’s been in space as long as this is subjected to forces from the Earth ’s and the Sun Myung Moon ’s gravity and the light from the sun . So you would expect it to tilt a little turn , specially when you consider that the rocket body is a big empty shell with a heavy railway locomotive on one side . But this was just tumbling closing - over - end , in a very stable way of life , ” Tanner Campbell , first survey author and a doctoral student at the University of Arizona Department of Aerospace and Mechanical Engineering , suppose in astatement .
" We have it away the booster had an instrument deck mount to its top remnant , but those press only about [ 27 kg ] 60 pound or so . We perform a torque counterbalance analysis , which showed that this amount of weight would have moved the rocket ’s center of gravity by a few inches – it was n’t nearly enough to account for its stable gyration . That ’s what leads us to call back that there must have been something more mounted to the front , ” he add together .
Secondly , the research worker were also strike by the foreign overlap craters it spring , made of an eastern volcanic crater about 18 meter ( 59 feet ) in diameter and a western crater about 16 meter ( 52 feet ) in diameter .
" This is the first time we see a double volcanic crater , " Campbell excuse . " We cognize that in the case of Chang’e 5 T1 , its impact was almost straight down , and to get those two crater of about the same size , you need two approximately adequate masses that are apart from each other . "
As for what the unrevealed loading was , Campbell and the team are n’t holding out for any answer .
" apparently , we have no musical theme what it might have been – perhaps some extra support construction , or extra orchestration , or something else , " he said .
" We likely wo n’t ever know . "
