THE MOON RANG LIKE A BELL

Uncategorized 3 Minutes

Though the Apollo lunar modules were built for the sole purpose of landing two men on the surface of the Moon, their usefulness didn’t end after ascending from the lunar surface. While on the moon, the astronauts placed seismic censors and NASA used the spent spacecraft for science, directing these modules for controlled crashed into the Moon. These crashes caused moonquakes, and scientists measured the vibrations moving through the Moon and found it rings like a bell.

Astronaut Bean, Apollo 12

The real goal of the seismic experiments was to figure out the Moon’s internal structure. Measuring how long the reverberations last, how powerful they are, and how big the waves get can reveal what the Moon is made of. Remote seismic stations were instrumental in this investigation, and they were deployed as part of the Apollo Lunar Surface Experiment Packages that astronauts set up on the Moon on Apollos 12, 14, 15, and 16; different versions were deployed on Apollos 11 and 17.

From when they were first set up to when they were remotely shut down in 1977, these ALSEPs recorded all kinds of seismic activity. The data was sent back to receiving stations on Earth where the signal was magnified by 10 million so scientists could interpret the signal.

Apollo 12’s ALSEP on the lunar surface

But something interesting happened on Apollo 12. After Pete Conrad and Al Bean landed at the Ocean of Storms on November 14, 1969, they left the lunar surface 142 hours into the flight. Eight hours later, they were reunited with Dick Gordon in the command module and sent their spent lunar module back to the Moon. It impacted about 40 miles away from the Apollo 12 landing site with the force of one ton of TNT. The resulting shockwave built up and peaked in just eight minutes. Then it took an hour to fully dissipate.

Simulation

Something similar happened on Apollo 13. The S-IVB impacted the Moon 85 miles from Apollo 12’s ALSEP — CMP Jack Swigert joked at the time that it was the only thing on that mission to go right. It hit with the force of 11 and a half tons of TNT. This translated to a seismic impact peaked after seven minute with shockwaves 30 times greater and four times longer than those from Apollo 12’s LM impact.

The vibrations from these two impacts lasted longer than scientists expected, far longer than any equivalent vibrations last on Earth. It was almost as if the Moon was ringing like a bell. This strange result forced scientists to think differently about the Moon and its composition.

The crater left by Apollo 13’s S-IVB impact.

It turns out that these impacts were characteristic of one of four types of moonquakes scientists studied from ALSEP data. Some moonquakes originate deep below the surface because of lunar tides, some are thermal quakes caused by the Sun thawing the frozen surface at the start of a new lunar day, and others are caused by impacting meteors. The fourth kind of moonquake is a shallow moonquake occurring roughly a couple of tens of miles below the surface. The lunar module and S-IVB both produced this kind of vibration, and these are the most violent types of moonquakes.

Between 1972 and 1977, scientists recorded 28 shallow moonquakes registering as high as 5.5 on the Richter scale. On Earth, that will move heavy furniture and crack plaster, but the vibrations usually die down in a matter of minutes.

It all comes down to water. There’s moisture in the materials that makes up our planet, expanding their structure. As energy from an earthquake moves through our planet, that damp material acts like a sponge, absorbing the energy of the waves and ultimately deadening their effects. But the Moon is dry, cool, and rigid, more like a solid rock than a sponge. So even if a moonquake is less intense, there’s nothing to deaden the vibrations. They just go back and forth through the body until the solid stone eventually stops them. The “ringing bell” is the shock waves reverberating through that stone.

        1. This is why I watch documentaries almost exclusively, then I follow up on-line. Watched another one yesterday about trying to drill to the earth’s core…..it seems to me that they are messing with things that should be left the hell alone! All in the interests of making money on new resources! They make the claim that it is unknown what is deep inside the earth, then make claims like “…the deeper your drill, the hotter it gets…” OK – if you don’t know what’s beyond a certain depth, then how do you know how hot it is? Why do they make these pronouncements as if they came from God himself??? And what might they be interfering with on the moon that could possibly cause serious repercussions here on earth? The moon has a lot of influence over our planet……SMDH

They could have presented themselves as an American company, tho, since China has started a branch here, from what I understand.

  10. going easy on bail, electronic monitoring (EM), and coddling felons is not a winning strategy…lawsuits might help.
    FTA
    Lawyers for the estates of Cooper and Shanate Guy, the victim in the first lawsuit, claim Cook County, Dart, and Evans put over 3,500 people onto the EM program, but only staffed 110 people to monitor an average of 850 violations per day.

    Dominiko Johnson, who allegedly killed Guy, was the 26th person accused of killing, shooting, or trying to kill or shoot someone in Chicago last year while on felony bail.

    Williams, who is charged with killing Cooper, was the 27th.

    Cook County and Chicago have an enormous problem of murder and attempted murder by people out on bail or released subject to electronic monitoring. In 2020, at least 51 cases were recorded of people out on bail shooting or shooting at victims. The details of the crime against Cooper, contained in the CWBChicago story, are heartbreaking.

    It is very difficult to win lawsuits against the justice system for failure to prevent crime, but perhaps these separate lawsuits have a chance of influencing the county to step up its enforcement.

    Mini ground report. When returning from Northern Michigan nearly a week after the 4th I was paying attention to gas prices. The prices in the Gaylord area had been less than those in Metro Detroit before the holiday, historically they’re usually 10 cents more.

    Leaving town we saw $4.69, then around Flint it was $4.79. We hit Telegraph road in Oakland County & down through Wayne County. It went up to $4.89 & then started skipping around a bit, at one point it was $4.49 like a mile South of where it had been $4.89. Most prices ended in 9 & a few in 5 but between those 2 limits.

    The station near our house was $4.49 but one week later it was $4.29. My mom mentioned that she’d seen it as low as $4.09 recently but I haven’t.

    Another price change is that certain “Dollar Stores” have now raised their prices to $1.25 per item…a first ever in my probably 2 decades of shopping in them…

    In our family situation the weekend was busy with a bridal shower for our future daughter-in-law, music ministry, baptisms (again) for the engaged couple, & street ministry for 3 of our 4 kids. Josiah’s wedding is in less than 2 weeks…

    My husband ended up separating from his recently acquired trucking job. He got a pretty severe case of sunstroke on his 3rd day in the field & discovered that some of the technology being used to track the fuel acquisition & delivery was faulty. He has an over-the-road job that begins right after J’s wedding, though is continuing to look for local options so that he might be home nightly. The OTR is good training on both enclosed trailers & flat beds so he is willing to work there for 6 months to a year, if need be. He’s hoping for a low to no touch option & driving an “A” truck. We’d appreciate prayer!

    Our granddaughter is precious & mostly asleep whenever we’ve spent time with her as her days & nights are mixed up. Our son went back to work last week & he & his wife seem to be adjusting quite well to parenting. Our middle son just came down with “covid” after being exposed by his roommates, 2 of whom were sick for a couple days but needed about a week before getting a negative test. Son can’t probably go to work this entire week now due to policies…I shared our Q-Tree protocols with him so hopefully those OTC meds & supplements can assist him in getting well quickly.

    Our dog killed a baby skunk while we were Up North & still smells of it a bit. Our daughter has remarked a couple times how she thinks Jules is thicker around the middle recently. We’re wondering if she might have gotten knocked up while being out in the unfenced yard Up North. Anyone know how long dog pregnancy gestation is? I don’t remember for our first dog as a couple had puppies back in 1994…

    Hope things are well with All Q-Treepers. It’s hard to keep up with all the reading & interaction here when there are so many things to handle in real life. God Bless  ❤

    A truck driver would amuse himself by running over lawyers. Whenever he saw a lawyer walking down the side of the road he would swerve to hit him, enjoy the load, satisfying “THUMP”, and then swerve back onto the road.

    (at this point some of you are probably wondering how the trucker could distinguish the lawyers from the humans. Obviously he saw the trail of slime they left!)

    One day, as the truck driver was driving along he saw a priest hitchhiking. He thought he would do a good turn and pulled the truck over. He asked the priest, “Where are you going, Father?” “I’m going to the church 5 miles down the road,” replied the priest. “No problem, Father! I’ll give you a lift. Climb in the truck.” The happy priest climbed into the passenger seat and the truck driver continued down the road.

    Suddenly the truck driver saw a lawyer walking down the road and instinctively he swerved to hit him. But then he remembered there was a priest in the truck with him, so at the last minute he swerved back away, narrowly missing the lawyer. However, even though he was certain he missed the lawyer, he still heard a loud “THUD”. Not understanding where the noise came from he glanced in his mirrors and when he didn’t see anything, he turned to the priest and said, “I’m sorry Father. I almost hit that lawyer.” “That’s okay”, replied the priest. “I got him with the door!”

  35. EXCERPT: “Top doctors and scientists at the leading U.S. public health agencies are “frustrated, exasperated and alarmed” about the direction of the agencies they work for, according to the authors of a Substack post published last week. They’re also embarrassed — about “bad science.” And many are leaving.

    “It’s like a horror movie I’m being forced to watch and I can’t close my eyes,” said one senior official with the U.S. Food and Drug Administration (FDA). “People are getting bad advice and we can’t say anything.” The comment was one of many culled from calls and text messages between officials and the article’s co-authors, Marty Makary M.D., M.P.H., and Tracy Beth Høeg M.D., Ph.D.

    Makary and Høeg said the officials who spoke to them agreed to be quoted — but only anonymously, for fear of professional repercussions. The National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC) are plagued with “low morale” and “high turnover,” officials told Makary and Høeg.

    “At the NIH, doctors and scientists complain to us about low morale and lower staffing: The NIH’s Vaccine Research Center has had many of its senior scientists leave over the last year, including the director, deputy director and chief medical officer,” they wrote.

    And it’s no better at the CDC, they said: “The CDC has experienced a similar exodus. ‘There’s been a large amount of turnover. Morale is low,’ one high-level official at the CDC told us. ‘Things have become so political, so what are we there for?’ Another CDC scientist told us: ‘I used to be proud to tell people I work at the CDC. Now I’m embarrassed.’”

    Officials complained the heads of their agencies “are using weak or flawed data to make critically important public health decisions, that such decisions are being driven by what’s politically palatable to people in Washington or to the Biden administration and that they have a myopic focus on one virus instead of overall health.”
