A spacecraft left behind by US astronauts on the lunar surface could be causing small tremors known as moonquakes, according to a new study.
Researchers revealed the previously unknown form of seismic activity on the moon for the first time through an analysis of Apollo-era data using modern algorithms.
Massive temperature swings that occur on the moon can cause human-made structures to expand and contract in a way that produces these vibrations, the report suggests. The lunar surface is an extreme environment, oscillating between minus 208 degrees Fahrenheit (minus 133 degrees Celsius) in the dark and 250 degrees Fahrenheit (121 degrees Celsius) in direct sun, according to a news release about the study. ...
Marusiak noted that every Apollo mission carried instruments for detecting moonquakes. But the Apollo 17 mission, launched in 1972, was noteworthy because it left behind an array of seismometers capable of detecting thermal moonquakes — or the tremors induced by the drastic heating and cooling of the lunar surface. “Thousands of these signals were recorded during an 8-month span from 1976 to 1977 on four seismometers deployed during the Apollo 17 Lunar Seismic Profiling Experiment, but the poor quality of data makes analysis difficult,” the researchers wrote. ... Scientists revisited the data for the first time in decades. The fresh analysis allowed the research team to conclude that a certain type of moonquake — called an impulsive thermal moonquake — did not come from natural sources but rather from the nearby spacecraft heating and cooling.
“Every lunar morning when the sun hits the lander, it starts popping off,” said study coauthor Allen Husker, a research professor of geophysics at Caltech, in a statement. “Every five to six minutes (there was) another one, over a period of five to seven Earth hours.

In the academic world, it’s “publish or perish”. So you’ve got to continually find new things to research. That’s my guess as to what happened here.
I’d like to say more, but I’m working on a research project to show how all the hot air emitted by the ladies on “The View” affects the orbit of Mars.
If that doesn’t get me a physics professorship at Caltech, I don’t know what will.
Un-possible. We all know Stanley Kubric faked the moon landings.
Bingo.
I would say that it's a misnomer to refer to these induced moonquakes as even only "tremors." More like: "microquakes."

We've reached the point where Bezos or Musk or Soros or Schwab or Zuckerberg or Gates could be a real life Bond villain.
Think of all the “earthquakes” that occur around high rises every day!
Climate change!
What a complete crock of sh*t!!
—”OK, who left their Disco mix tape running in the cassette data recorder?”
They are hiding illegals and thought no one would notice.
Cheaper than the NYC migrant hotel rate.
As an aside, I always thought it curious that 007 was in a moon man suit, but all the women are dressed like hooters waitresses. What? They don’t get cold?
Yep, just trying to shake that foreign object
off. Whole lot of shaking going on according
to Jerry Lee Lewis.
That’ll rile up the moon-darters and lunar spotted owls.
Big angry incoming!
Man-caused in the sense that man sent that lander to the moon.
But caused by the sun sending sunshine.
I guess the greenie weenies will use the consequences of sunlight hitting man-built structures and objects as justification for back to nature elimination of 21st century conveniences.
Yeah right. The capsule is like 0.000000000000000000001% of moon’s mass.
Or it could be the power behind the throne no one talks about - the Rothchilds with their $500 trillion fortune.
Yah, or a truck drove by.
CNN. What do you expect? C’mon.
Hmmm - maybe that means the Government will need to “blow up” the “moon landing sites” to prevent further “moon quakes”...
That way, when someone lands on the moon in the future they can say - sorry, “all gone”. Oops...
No proof that we didn’t land on the moon then....lol
Nah....that could never happen could it...
I’m amazed that there is sensitive equipment that can detect minor noises from the contraction of metals as their temperature changes. Nothing that can legitimately be called a moonquake.
But the equipment isn’t causing the noise. It’s the sunlight acting on the equipment.
And what is supposed to be the conclusion of the useless article? That the USA is evil/racist/sexist/homophobe/trannophobe for leaving the modules on the moon and should start giving reparations to anyone who is aggrieved?
It’s really just the thought that there is this metallic bug shaped thing with legs on it’s surface that is freaking out the moon.
Or maybe it’s the giant worms that are laying in wait for more astronauts.
