When Vladimir Putin was a young man he was witness to his country’s space program being eclipsed by the United States. There are many reasons that the United States won the space race with the USSR, but Rocketdyne’s Saturn V F-1 engine was the element that the Soviet space program couldn’t replicate. It was a rocket engine that has no practical use for piddling around in Earth orbit. The F-1 is the top shelf engine of space exploration.

Who Are Those Guys?

If there was a moment when the Soviet engineers said in wonder, “Who are those guys?,” it was when they saw the first massive Saturn V blast off using only five engines. They were working on a heavy-lift rocket that used 30 rocket engines in the booster phase. The idea that a Moon rocket could be designed using only five engines was laughable.

The USSR attempted four launches with their version of the Saturn V rocket called the N1 rocket. All four attempts failed. The Saturn V rocket had 13 successful launches in 13 attempts. One rocket (unmanned Apollo 6) had vibration issues and failed to make the desired orbit, but the launch was successful. NASA and its contractors crushed the Soviet Moon rocket in performance and reliability.

Comparing Watermelons To Sour Grapes

The Soviet N1 Moon rocket used the NK-15 engines on the first, or booster stage. Compared to the Apollo Saturn V F-1 engines, the USSR effort was similar to strapping a bunch of bottle rockets together to lift a person off the ground.

Each of the 30 NK-15 engines could lift about 1,500 kilonewtons or kN (1 kilonewton equals 224.81 pounds of force) compared to a single F-1 engine thrust of 7,000 kN. The total thrust of the first stage of the Soviet N1 Moon rocket was 45,400 kN, which was significantly greater than the Saturn V’s booster thrust of 35,100 kN and the N1 Moon rocket was 215,000 kg (480,000 lbs.) lighter.

However, the N1 required four stages compared to the Saturn V’s three-stage rocket, and the N1 booster stage could only burn for 125 seconds, while’s United States booster stage burned for 168 seconds. The big difference was the size of payload that the Saturn V could deliver to the Moon. USSR’s N1 could only put a 23,500 kg payload (51,800 lbs.) out of Earth orbit to the Moon, while the Saturn V could send a 48,600 kg (107,100 lbs.) payload.

The Rocketdyne F-1 engine was responsible for powering everything needed for a Moon landing and safe return off the surface of the Earth and it did it better than any other rocket engine in the history of space exploration.

As scientists are finding more planets orbiting other stars it is becoming more of a reality that we are not alone in the universe. We may never be able to contact or observe life on other planets, but no one can deny the possibility that life might take root these islands in space. Still, it is important to remember that life on Earth is due to special circumstances.

Ten Factors Required For Life On Earth

A planet orbiting a star does not necessarily result in the development of life. On our planet, we have at least ten factors that allowed life to develop.

1. Not Too Close to Other Stars (Location, location, location)

If our solar system was located near the center of the Milky Way Galaxy, life probably would not have been able to develop on Earth. Stars are dangerous. They do bad things including spitting out radiation that destroys the basic structures of complex life. A planet in a solar system with other stars in the neighborhood is asking for trouble.

2. Our Sun is Special

Life on any planet requires a star, but not just any star will do. Size matters in the development of life. So do the qualities of the star. Our Sun is bigger than most, but still it is a relatively small, stable star and it’s been that way for over four and a half billion years. It will be stable for about another 5 billion years. It also has a treasure of heavy elements that are necessary for planet formation. Without planets, there is no life.

Life around stars of different sizes are possible, but our Sun seems to be about the perfect size for the development of life. In addition, our Sun is 85% brighter than the rest of the stars in the Milky Way, which has been vital in ‘powering’ our planet.

3. A Star’s Habitable Zone

Planet hunters and the media have made a major issue out of the concept of the ‘Goldilocks Zone.’ This is the area around a Sun where a planet is not too close, nor too far away. It is an important aspect of the potential for development of life on a planet, but it is only one factor of many. For Earth, we are resting in the orbit that is just right.

4. Moon

It’s hard to overstate the importance of the Moon for the development of life on Earth. First, the Moon was likely formed in a collision when a small planet-sized object hit Earth and tilted our axis (more on this later.) In addition, the Moon has slowed the Earth’s rotation down (more on this later,) and helped enhance the tidal movement of the Earth’s oceans. The Moon has played an important role in human activity, but just as an important role for all our planet’s species.

5. Size of the Planet

Again, size matters. If a planet is too big and the gravity will inhibit the formation of larger, more complex molecular organic structures. Too small and there can be no atmosphere. Earth is in the zone.

6. Axial Tilt

If Earth’s axis was perpendicular to the plane of the solar system the Sun would heat up the equator creating a zone too hot for most life forms. The poles would have minimal solar heating and would be extremely cold. In between would be the combat zone between hot and cold. Constant violent storms and wind would batter the mid-latitudes.

The tilt of the Earth causes solar heating to warm one hemisphere and allows the other to cool down. Every six months the warm/cool cycle swaps hemispheres. This creates storm systems in both hemispheres, but they act to distribute the warmth more evenly. The tilt of Earth’s axis is almost perfect for nurturing life.

7. Length of Day (spin)

We take the 24 hour day for granted. We shouldn’t. Last year Takanori Sasaki, a planetary scientist with Kyoto University, pointed out that the Earth originally spun so fast that its ‘day’ was only four hours long. Multicellular life didn’t develop on Earth until the day was 23 hours long. It’s is not clear at what point a planet’s rotation makes it habitable, but it seems obvious that a planet’s spin is a factor in the possibility of life formation.

8. Atmosphere

It may be obvious that an atmosphere is required for the development of life, but there are qualities to an atmosphere that are also required. The atmosphere cannot be too thick or too thin. It has to consist of an oxidizer, such as oxygen, to promote chemical reactions in cell structures. There is more to Earth’s air than just air.

9. Liquid Water

Water is necessary for all life that we are aware of, even though it is more important to some species than others. Liquid water is even more important to life than water vapor or ice. It is not an accident that the development of life happened on a planet where 71% of the surface is covered with liquid water.

10. Continent to Ocean Ratio

It’s not obvious, but life on Earth has been helped by the ratio of land to ocean. Land tends to have more temperature variance than the oceans between summer and winter. Land that is not covered in ice or vegetation absorbs much more heat in the summer. If most of our planet consisted of continents, the temperature change from summer to winter would be more dramatic, and less friendly to life.

Earth is Unique, Not Rare

Life on Earth was not an accident, nor is it divine. The conditions that led to the development of life here must exist on millions of planets, but there are an estimated 100 billion planets in the Milky Way Galaxy alone. We are unique, but we cannot be alone. Give life an opportunity and it will seize it.

The Almost Super, Blue, Blood Moon

The western United States experienced a total lunar eclipse this morning just before dawn. I set up at 4:30 AM on a vantage point at the northwestern edge of Reno, Nevada with my camera and my telescope. It wasn’t as awe-inspiring as the total solar eclipse in Oregon on 21 August of last year, but it was impressive.

Blood-red Moon

Eclipsed Moon over Reno, Nevada

Unfortunately, Reno has been plagued with near constant high clouds this winter and this morning was more of the same. It allowed a good view of the eclipse of the Moon with the naked eye, but all my telephoto images lacked the clarity that I would have liked.

Coyotes Have the Last Howl

The best moment for me occurred after totality ended. As the Moon came out of Earth’s shadow, multiple packs of coyotes began to howl. It was amazing and a little unnerving. One coyote had to be within 150 meters, just below me. It is obvious that Reno is surrounded by packs of coyotes taking advantage of the food sources in human communities…including cats and dogs. Below is a recording of one of the two howling events.

I have seen several lunar eclipses in my life and it is fascinating to watch the white-washed Moon suddenly change to deep brownish red just before totality. The Moon becomes three dimensional and looks like a ball hanging in the sky.

My God, it's surrounded by stars!

Blocking the Sun’s reflected light allows us to see the stars near the Moon (click on image to see larger version)

During this eclipse, I noticed more stars in my images than in past eclipses. The high clouds hid almost all the stars from the naked eye, but the telephoto lens was able to capture them.

Buh, bye Moon!

A last look at the partially eclipsed, Moon setting behind the hills

Not Quite Super

The media plugged this Moon for this eclipse as the ‘Super’ Moon. They can get away with that, but the Full Moon of 1 January was the 2018 Super Moon. It was closer to Earth when it reach the Full Moon phase at the beginning of the month. This Full Moon was also near apogee when it became a Full Moon, but not as close as the New Year’s Day Moon. It was close, but not quite; however, an “Almost Super Moon” doesn’t have the same zip as Super Blue Blood Moon.

It was entertaining to listen to reporters try and explain the terms when they had no clue what they were talking about. Makes me think that maybe I’m entertaining when people read my articles…but not for the reason I would hope.

If you like the coyotes howl, below is the second event that I recorded a few minutes after the first one. I didn’t have my camera focused on the Moon at first, so I added images over the sound at the beginning, but the end is the real time video of the post-totality Moon with the coyotes singing in the background.

blue Moon, Earth's shadow, eclipse, lunar eclipse, Moon

The last day of January will start with the second Full Moon of the month (a.k.a.:  a Blue Moon.) It will then transform into a total lunar eclipse. Asia, the Pacific, and western North America will be able to watch the Earth’s shadow move across the Moon.

However, there’s a catch. It is an early morning eclipse in western North America and it will happen just before the Moon sets in the west. Locations with mountains to the west may see the Moon set before the total lunar eclipse ends.

In some places, the rising Sun will be brightening the eastern sky as the totality ends. The Sun will be rising on Earth as the Earth’s shadow moves off of the Moon. The Earth’s Shadow is almost four Moon diameters wide, but for most U.S. cities it will pass through the southwest quadrant of the shadow. Totality will last just over an hour.

NASA’s Orion Capsule: A ‘Look Busy’ Project?

NASA has a publicity campaign for the next generation of spacecraft. It is the Orion capsule, and it is touted as the spaceship that will take us back to the Moon and beyond. The problem is that all the talk doesn’t match reality.

8 July 2011, STS-135 – The final launch of a USA spacecraft

On 8 July 2011, I stood several miles away from Kennedy Space Center and watched the end of the United States manned spacecraft program. I stood in the warm sunshine of Florida as the last Space Shuttle (STS-135) soared into the sky. Since then NASA has put our astronauts in space by paying Russia to take them to and from the International Space Station (ISS.) 

A few months before that last Space Shuttle flight NASA announced the development of a new spacecraft called Orion. The announcement came so abruptly that it seemed that NASA was unaware it wouldn’t have a spacecraft to send humans into space until just before the end of the Space Shuttle program.

Orion – A Spacecraft of Contradictions

The Orion program, for all its hype, seems to have major flaws that NASA doesn’t seem to notice, or perhaps, hopes the public won’t notice. NASA’s description of the purpose of Orion:

For the first time in a generation, NASA is building a human spacecraft for deep-space missions that will usher in a new era of space exploration…and this new spacecraft will take us farther than we’ve gone before, including to the vicinity of the Moon and Mars…the Orion spacecraft is designed to meet the evolving needs of our nation’s deep space exploration program for decades to come. Orion deep space exploration missions…will help put NASA and America in a position to unlock the mysteries of space and to ensure this nation’s world preeminence in exploring the cosmos.

Orion a USA Spacecraft????

Lockheed Martin Corporation is designing and building the capsule of Orion. Like the Apollo capsule, Orion can only be separated from the Service Module for a short period of time.

The Service Module is the business section of Orion. It supplies all the power, fuel, oxygen, and is the primary propulsion of the spacecraft. Anyone familiar with Apollo 13 knows what happens to the capsule when the Service Module is non-functioning. The Service Module is being built by Airbus, a French corporation, for the European Space Agency.

Orion Capsule: A Human Storage Shed in Space

In Space, Size Matters

The Apollo capsule had a volume of 5.9 m³ (210 ft³.) Apollo astronauts were able to use the 6.7 m³ (235 ft³) space in the Lunar Module (LEM) during the three day trip between Earth and Moon. The total volume of the Apollo capsule and LEM was 12.6 m³ (445 ft³) for three astronauts. On the return, the Apollo astronauts were restricted to the capsule. Each astronaut had about 2 m³ in the capsule or 4 m³ in the capsule/LEM configuration.

Orion has 8.95 m3 (316 cu ft) of habitable space for four astronauts. This is slightly more cubic meters per astronaut than the Apollo capsule and much less than Apollo’s capsule/LEM configuration. The idea that Orion is capable of taking four astronauts on an eight-month journey to Mars is absurd. Orion is only for use in short-term, near-Earth missions.

NASA has briefly acknowledged the space issue in a video. Amber Gell of Lockheed Martin briefly touches on the need for an add-on crew habitat. She implies that it is an issue that NASA has yet to address. If it takes NASA twelve years to design and build a slightly bigger version of the 1960’s Apollo spacecraft, how long will it take them to build a crew quarters that four people can live in for up to three years?

NASA’s Misleading Video about Orion

NASA has been pumping out videos of engineers explaining how Orion is the next great achievement of the space agency. The videos cover a variety of subjects and some are pre-test and post-test news releases of Orion’s systems and structure. One video features Kelly Smith, a NASA Engineer, who explains how Orion is being designed to deal with the radiation from the Van Allen Belts around Earth.

The 2014 NASA video, titled, “Orion: Trial By Fire,” describes the challenges of the first test flight, including a dramatic description of the dangers of flying through the radiation of the Van Allen Belts above Earth. He explains that Orion will be designed to protect the astronauts as they fly through these dangerous regions.

The problem is that NASA already solved that problem with Apollo. They either fly around the Van Allen Belts, or through the thinner sections, as described by a video by Amy Shira Teitel of Vintage Space, and a video by Paul Shillito of Curious Droid.

There is a radiation issue in space, namely cosmic radiation, and it is a problem on long trips beyond Earth orbit; however, as Lara Kearney of NASA’s Orion Crew and Service Module’s Office explains in another NASA video, that they don’t have the answer to the cosmic radiation problem. This video contradicts the enthusiastic Smith video and raises the question:  Does NASA know what they are doing?

Orion:  The NASA Glacial-Paced Project

In May 1961, President John F. Kennedy asked Congress to fund a space program to take to the Moon and safely back. From the time of his speech in 1961 to the end of 1972, NASA launched the five of the six manned Mercury missions, designed, tested, built, and launched 10 Gemini manned missions, designed, tested, built, and launched 11 Apollo manned missions, landed men on the Moon, and overcame a disaster that delayed the manned launches for 21 months. Eleven years, three complete rocket programs, 27 manned missions, six successful Moon landings, no prior experience.

Orion, a slightly larger version of the Apollo capsule, only useful for short-term habitation in near-Earth orbit, is taking twelve years. Something is amiss.

NASA’s ‘Look Busy’ Project?

NASA definitely needs more funding, but something else is wrong. NASA’s Orion project doesn’t make any sense unless they are attempting to create the appearance that they are moving forward with a manned space program. The Orion project is, at best, an Earth to orbit elevator. It can’t meet any of the stated manned spaceflight goals of NASA. The question is, why isn’t NASA aware of these issues, and if they are aware, what is the agenda that is causing them to promote a project that is meaningless to the stated goals of deep space flight?

May 1968 – Student injured in France in clash with police

1968. Fifty years ago our country was in chaos. Only five years had passed since President John F. Kennedy had been assassinated. The man who became President, Lyndon B. Johnson, had accomplished amazing milestones in civil rights, protections for the elderly (Medicare and Medicaid) and had expanded programs in public broadcasting and the arts, but the country was torn apart by the war in Vietnam, and he had increased the number of U.S. troops in the war to over half a million.

The National Aeronautics and Space Administration (NASA) was still recovering from the  fire in January of the previous year that killed three astronauts as they sat helplessly in the command module on the launch pad, and the Apollo program had yet to launch a manned mission with only two years left to honor President Kennedy’s goal.

At the start of the year, everything in the world seemed to be collapsing. The year would test our society’s threshold of endurance. These are twelve days that defined 1968. (Source:  Wikipedia – 1968)

Captured crew of the USS Pueblo giving the finger to North Korea

  • January 23
    • North Korea seized the USS Pueblo, creating an international incident that remained in the news for most of 1968. North Korea claimed the ship was spying on their country and violated its territorial waters. Its mission was to observe and gather intelligence and at the time of capture, the crew attempted to destroy classified information on the Pueblo, but only succeeded in destroying a small amount of the documents and equipment. One crewmember was killed by North Korean fire in the attempt to capture the boat. The crew was tortured and starved during the eleven months of imprisonment. They were released just before Christmas 1968. The USS Pueblo is still held in North Korea and is still a commissioned ship of the United States Navy.
  • February 13
    • Civil rights disturbances occur at the University of Wisconsin–Madison and the University of North Carolina at Chapel Hill. This would be one of many protests, sit-ins, and riots, in the United States, England, France, Germany, and other countries over civil rights, the Vietnam war, and other social issues. Many of those involved in the year of civil disobedience would be injured or killed in clashes with law enforcement.
    • The Florida Education Association (FEA) initiates a mass resignation of teachers to protest state funding of education. This is, in effect, the first statewide teachers’ strike in the United States.
    • NET televises the very first episode of Mister Rogers’ Neighborhood.
    •  
  • March 16
    • Vietnam War – My Lai Massacre: American troops kill scores of civilians. The story will first become public in November 1969 and will help undermine public support for the U.S. efforts in Vietnam.
    • President Lyndon B. Johnson, the incumbent, narrowly won the first Democratic primary to a minor candidate on March 11, and U.S. Senator Robert F. Kennedy entered the race for the Democratic Party presidential nomination. President Johnson would end his campaign two weeks after Kennedy makes his announcement.
    •  
  • April 4
    • Martin Luther King Jr. is assassinated at the Lorraine Motel in Memphis, Tennessee. Riots erupt in major American cities, lasting for several days afterward.
    • A shootout between Black Panthers and Oakland police results in several arrests and deaths, including 16-year-old Panther Bobby Hutton.
    • A double explosion in downtown Richmond, Indiana kills 41 and injures 150.
  • May 17
    • The Catonsville Nine enter the Selective Service offices in Catonsville, Maryland, take dozens of selective service draft records, and burn them with napalm as a protest against the Vietnam War.
    •  
  • June 5
    • U.S. presidential candidate Robert F. Kennedy is shot at the Ambassador Hotel in Los Angeles. Sirhan Sirhan is arrested. Kennedy dies from his injuries the next day.

Pope Paul VI: The man who brought the Church into couple’s beds

  •  July 25
    • Pope Paul VI publishes the encyclical entitled Humanae vitae, on birth control. This voided a church commissioned study (Pontifical Commission on Birth Control) that determined birth control to NOT be inherently evil, and that couples should decide for themselves about the use of birth control. The Pope’s decision inserted the church into a conflict that continues to this day.
  • August 20
    • The Prague Spring of political liberalization ends, as 750,000 Warsaw Pact troops, 6,500 tanks, and 800 planes invade Czechoslovakia. It is dated as the biggest operation in Europe since WWII ended.
  • September 6
    • 150 women (members of New York Radical Women) arrive in Atlantic City, NJ to protest against the Miss America Pageant, as exploitative of women. Led by activist and author Robin Morgan, it is one of the first large demonstrations of Second Wave Feminism as Women’s Liberation begins to gather much media attention.
  • October 11
    • Apollo program: NASA launches Apollo 7, the first manned Apollo mission (Wally Schirra, Donn Eisele, Walter Cunningham). Mission goals include the first live television broadcast from orbit and testing the lunar module docking maneuver. The United States is back in space for the first time since the Apollo 1 disaster.
    • In Panama, a military coup d’état, led by Col. Boris Martinez and Col. Omar Torrijos, overthrows the democratically elected (but highly controversial) government of President Arnulfo Arias. Within a year, Torrijos ousts Martinez and takes charge as de facto Head of Government in Panama.

Send Our Trash Into Space

A.  Plastic grocery bags and water bottles are a BIG problem on Earth.

B.  Cosmic rays are a BIG problem in human space travel.

The solution to both problems is simple. Send our recycled plastic trash into space and use it to shield ships from cosmic rays.

This is not a joke.

Cosmic rays are highly energetic particles that pass through most atoms until they hit a nucleus dead on. They are a form of radiation that is the single largest health threat to astronauts traveling beyond Earth’s natural magnetic shield. 

Plastic: China doesn’t want it, and we need it in space

A Problem With A Solution

Hydrogen, which can be found in polyethylene structure of plastic grocery bags and water bottles, is effective against cosmic rays because the hydrogen atom has less space for a cosmic ray to pass through without hitting the nucleus. If spaceships were built incorporating polyethylene shielding, astronauts would be better protected from cosmic rays without adding tons of dense metal-based shielding to the spacecraft.

Recycling polymer materials and sending it into space would relatively expensive; however, if we had a major Moon and Mars exploration program the cost could be justified. Ships could use the materials once they had an inventory in space. By starting an inventory recycled plastic in orbit around Earth, the future cost of space exploration could be reduced. In addition, the amount of wasted plastic in our environment would be reduced. 

At a time when China is now refusing to accept our raw recycled materials, we need to become creative on new uses for the stuff that won’t ever go away.

_dsc6558-2Great Father Sun, you are the origin, the center, the focus, you are the constant. I see you as you cross the sky. I feel your warmth. You make the food grow and all life possible. Without you, we could not see. Without you, there would be no rain. When you light the sky above me, I see your power. At night you shine on our Mother Moon. 

Great Mother Earth, you are our source, our foundation, the root of all life on our planet. You give me a home. You give me air to breath, water to drink, and food to eat. You give me all that I need. Without you I would be dust and rock floating in the vast cavity of space.

_dsc6362-2Mother Moon, you are the giver of life. You are the spark that lit the fire of life on Earth. Your touch tilted the Great Mother Earth and gave us seasons. Your pull creates the tides. Without you, the Great Mother Earth would be uninhabitable.

I pray forgiveness for what we have done. I believe that you sought to have us progress forward, moving from beasts that were motivated by lust and desire, to creatures of intelligence and compassion that sought harmony and grace.

Instead we have devolved back into beasts. We have brought on shame and failure to not only ourselves, but to all life. We have no excuse. We know what is proper, and what is not, but we have chosen to embrace the improper.

Great Father Sun, Great Mother Earth, Mother Moon, I know the seasons are necessary for life, and I know, just as the seasons bring warmth in the summer and cold in the winter, so to the seasons of humanity wax and wane.

This is a season of darkness for humanity, but I pray that you will intercede. The darkness of this season is hurting and killing the innocent, not the weak. Those of money and power seek to destroy, not build, and those who gave them power have failed as human beings and celebrate the destruction.

Intercede for those who need you. Intercede for the honor of life. Intercede because it is the correct thing to do. Intercede because those who have intelligence know the danger of violent aggression and know that it is not the answer to battle the unethical, wicked, and stupid.

Great Father Sun, Great Mother Earth, Mother Moon, it is time to act on our behalf. 

How Did Earth Get A Moon?

Earth's Only Child

Earth’s Only Child

How Earth was blessed with a Moon was anybody’s guess 50 years ago. In our solar system it’s a relatively big moon. At slightly over 1,000 miles (1,700 km) in diameter it’s about half the size of planet Mars and there are only four moons (Ganymede, Titan, Callisto, and Io) that are bigger than Earth’s Moon.

Pre-Apollo Mission Theories
So how did Earth end up with a natural satellite that rivals the biggest moons of  the massive planets Jupiter and Saturn? And why just one?

Moons of our Solar System

Moons of our Solar System

Prior to the Apollo missions to the Moon, there were three main theories of the origin of the Moon. First, was the adopted daughter theory. It proposed that our Moon wandered into Earth’s gravitational pull and was captured. Second, was the mother/daughter theory that suggested the Moon was spun off from the Earth when it was still a molten blob of spinning material. The final theory was the sister theory where both bodies that formed side by side.

Hard Evidence: The Destroyer of Theories
When the Apollo missions came back to Earth with Moon rocks the three existing theories took a big hit. Had the Moon rocks matched the composition of Earth rocks then scientists could dismiss the adopted daughter theory because a wandering Moon wouldn’t likely have rocks similar to Earth’s. If the composition of the Moon rocks were different then they could dismiss the other two theories. What no one saw coming was the idea that the Moon rocks would match the composition of our Earth rocks, except for a lack of iron. The rocks were the same, but different.

None of the theories really met the evidence in hand, but now the geologists had a vital clue. When Earth first formed all the elements were mixed throughout the molten mass that would become our planet. As time passed most of the iron sank deeper into the mass to become Earth’s core. The evidence suggested that the Moon must have formed from Earth’s material after the iron sank into the core.

The New Theory: Impact Earth
It was clear the material for the Moon had to come from Earth, but the transfer of material had to occur after the most of the iron was not mixed in with the shallow layers of molten Earth. Enter the Impact Theory.

Scientists proposed that the Earth must have been hit with a large object (about the size of Mars) that pushed out shallow molten material into a near Earth orbit to create our Moon. The theory assumes the object was absorbed into Earth’s mass and didn’t significantly change the composition of the Earth or the Moon. Those are big assumptions.

The Little Bang Theory
Recently scientists are suggesting a new theory for the formation of the Moon that proposes a natural nuclear explosion blew off part of Earth’s shallow material after most of the iron sank into the core. The idea of natural nuclear reactions are not new. Radioactive material will always start a chain reaction upon reaching its critical mass and we have evidence that Earth has had multiple natural nuclear explosions in the past. It simply requires enough radioactive material to consolidate in close proximity to start a chain reaction. If it is radioactive and it reaches critical mass, BANG! A nuclear explosion.

So is this it? Do we now know how the Moon was formed? Not Exactly. Scientific knowledge is like the work of a detective. Learn something new and you can rule out certain possibilities, but it takes decades, sometimes centuries, to understand enough of what ‘couldn’t have happened’ in order to understand what did happen. It is likely we won’t have many more answers coming until we have scientists working on the Moon again. It’s hard to gather the evidence when you aren’t at the scene of the crime.
