India ’s moon bird of passage may have just detected the first evidence of a " moonquake " since the seventies .
The Instrument for Lunar Seismic Activity ( ILSA ) attach to the Vikram lander detect the seismal activity on the surface of themoonAug . 26 . Vikram land on the moonlight ’s south pole Aug. 23 as part of the Chandrayaan-3 mission — India ’s first mission to the lunar surface .
Chandrayaan-3 lunar rover on the surface of the moon on August 30, 2023.
If it ’s corroborate , the moonquake — which the mission detected alongside other activity including the movements of India ’s Pragyan bird of passage — could give scientist a rare brainwave into the mysterious churning entrails of Earth ’s lunar companion .

The lander " has record an effect , come along to be a natural one , on August 26 , 2023 , " The Indian Space Research Organisation ( ISRO)wrote on X , formerly Twitter . " The author of this event is under investigation . "
The Apollo lunar missions between 1969 and 1977 first detected seismic activity on the Sun Myung Moon , which turn up that the moon had a complex geologic structure hidden late within , rather than being uniformly rocky like the Martian moons Phobos and Deimos .
In recent age , in advance analysis tools and computer models have enabled scientists to sift through the data forgather by Apollo and other deputation and build up a clearer picture of the Sun Myung Moon ’s mysterious interior . A2011 NASA studyrevealed that the lunar month ’s core , much like Earth ’s , was likely made up of smooth Fe surrounding a dense , solid iron ball .
In May 2023 , researchersused gravitative field datato confirm this iron core guess , while also suggesting that blob of the moon ’s liquefied blanket could be tell from the relief , swim to the surface as clustering of smoothing iron and generating quakes as they went .
But these findings are just the beginning of the moon ’s secret . charismatic flying field are produced inside planetary bodies by the churning movement of fabric in planets ' electrically conductive liquefied cores .
Today the inside of the non - magneticmoonis quite dissimilar from Earth ’s magnetized innards — it ’s dense and mostly fixed , containing only a small out inwardness region that is fluid and liquefied . scientist believe that the moonlight ’s insides cool down moderately rapidly and evenly after it mould around 4.5 billion years ago , meaning it does n’t have a strong magnetic landing field — and many scientists trust it never did .
— Will Earth ever lose its moonshine ?
— How many moons does Earth have ?
— Who owns the moon ?
How then , could some of the 3 billion - yr - old rocks retrieved duringNASA ’s Apollo charge face like they were made inside a geomagnetic flying field brawny enough to rival Earth ’s ?
It is questions like these that the Chandrayaan-3 could help to answer . As the mission ’s lander and rover are both solar - powered , they are currently in sleep modality until the Sun Myung Moon exits its roughly 14 - day Nox . When the sun hits the face of the lunar south pole again on Sept. 22 , both tools stand poise to search for the answers .
