The current theory for how the Moon was formed is the Giant Impactor Theory. This theory states that a small planet, around the size of Mars, smashed into the Earth. After this impact heated material from both Earth and the small planet, known as Theia, formed a disk of debris around Earth. A while later the material in orbit formed together into the Moon. That is one of the current theories for how the Moon was formed, but now that theory doesn’t seem to hold up to scrutiny. If the Moon was formed from debris from both Earth and Theia then it would be reflected in the Moon’s chemical composition. Instead, the Moon shares its composition with the Earth alone.
The newest emerging theory was proposed by the researchers Raluca Rufu, Oded Aharonson, and Hagai B. Perets. Their theory replaces a single major impact with multiple smaller impacts. The process afterward would be pretty much the same. A debris disk would’ve been created around the Earth, then in time that disk would become the Moon. The reason this theory is proposed as a more likely formation model for the Moon is because these minor collisions would mean that the amount of foreign material would be minuscule. This would explain why the chemical composition of the Earth and the Moon are so similar.
This theory has not replaced the Giant Impactor Theory yet. The possibility that all of the debris that went into the formation of the Moon being solely from Earth after the collision between its collision with Theia unlikely, but the possibility that Theia and the Earth shared a similar chemical composition isn’t as negligible. Nicolas Dauphas, a planetary scientist from the University of Chicago, concluded that if Theia formed at roughly the same distance from the Sun as Earth then they would share a nearly identical chemical composition. Until more research is done it is unknown which theory is more likely to be correct.
NASA Will Make a Big Announcement About Unidentified Anomalies
NASA will release a major report on UFOs, or “unidentified anomalous phenomena” (UAP).
The briefing will be held at the agency’s Washington DC headquarters at 10:00 EDT (14:00 UTC) on Thursday, September 14. The video player below streams the discussion live.
NASA commissioned an independent study group of 16 scientific, aeronautical, and data experts led by astrophysicist David Spergel in 2022 to produce the findings.
NASA says the study group will “examine UAP from a scientific perspective and create a roadmap for how to use data and the tools of science to move our understanding of UAP forward.”
The team’s full report will be posted online by NASA 30 minutes before the briefing.
This report will be released in accordance with NASA’s openness, transparency, and scientific integrity. When the study was announced last year, NASA’s Science Mission Directorate assistant deputy associate administrator for research, Daniel Evans, said, “We take that obligation seriously and make it easily accessible for anyone to see or study.”
UAP sightings were once the domain of conspiracy theorists and sci-fi, but recent high-profile US military sightings have legitimized them.
US authorities are taking UAPs seriously because they may be Russian or Chinese experimental aircraft being tested for national security.
Also possible is extraterrestrial life. NASA is open to all possibilities, but this week’s announcement won’t reveal alien lifeforms visiting Earth.
Instead, the report may outline new protocols to help the agency collect UAP data in the future.
“The report informs NASA of future data collection opportunities to shed light on UAP’s nature and origin. The announcement’s brief NASA statement said the report is not a review or assessment of previous unidentifiable observations.
“There are currently a limited number of high-quality observations of UAP, which make it impossible to draw firm scientific conclusions about their nature,” the agency said.
NASA’s DART probe successfully collided with an asteroid.
At the time of impact, the impactor vehicle, about the size of a vending machine, was moving at about 14,000 mph.
After traveling for over a year, NASA‘s Double Asteroid Redirection Test (DART) mission, which attempted to provide answers, “Could a specially crafted satellite be used to divert an asteroid from its planet-destroying course? How about a number? “has effectively impacted the Dimorphos asteroid. However, NASA ground control has confirmed that the DART impact vehicle has intercepted the target asteroid. The results and data from the collision are still being received. Yes, Dimorphos is about the size of a football stadium, but space is very big, extremely dark, and both the asteroid and the spaceship were traveling rather quickly at the time.
“It’s been a successful completion of the first part of the world’s first planetary defense test,” NASA Administrator Bill Nelson said after the impact. “I believe it’s going to teach us how one day to protect our own planet from an incoming asteroid. We are showing that planetary defense is a global endeavor and it is very possible to save our planet.”
In an effort to investigate the employment of defensive satellites as a method of planetary defense against Near Earth Objects, NASA launched the DART mission in November 2021. Nearly 68 million miles from Earth, the DART impactor vehicle, about the size of a vending machine, tragically crossed Dimorphos’ path while traveling at about 14,000 MPH.
It remains to be seen if future generations of a planetary defense system will be packed with satellites ready to go full June Bug vs. Chrysler Windshield against real planet-killer asteroids. Dimorphos is one of two asteroids that are gravitationally entangled; its parent rock is more than five times larger than Dimorphos itself, but both are dwarfed by the space rock that struck Earth 66 million years ago and destroyed 75% of the planet’s multicellular life while gouging out the Gulf of Mexico.
Various Companies Partner Up to Put a Mobile Phone Network on the Moon
The world of science and technology brings us yet another crazy possibility that’s going to be explored quite soon. Fourth Generation Cellular Networks are seeing implementations on various places. One of them could be the natural satellite orbiting the earth: The Moon.
A partnership between Nokia, Vodafone and Audi is looking to implement cellular networks on the moon sometime next year. Even if the proposition sounds crazy, it seems like they have a lot of plans to make this dream a reality.
Vodafone will be designing the lunar network and will make use of equipment designed by Nokia Bell Labs. This connectivity will allow two Audi Lunar Quattro rovers to communicate wirelessly with a base station at the Autonomous Landing and Navigation Module.
Using existing satellites, mission organizer Part Time Scientists will also be able to live stream scientific data and HD video content from the Moon to viewers on Earth. In other words, we will be getting some very detailed views of Earth for public viewing.
The networking equipment will be launched into space aboard a SpaceX Falcon 9 rocket. If you think it’s going to be very heavy and sloppy to handle. Nokia’s engineers have worked really hard to make it weigh less than one kilogram.
We’re seeing the vestiges of life in the moon very frequently now. All thanks to the options becoming more and more accessible with the fast advancements in technology. Of course, this rapid growth is far from reaching its peak potential.
Who knows? Maybe we will be able to look at interplanetary travels and living. The sky is the limit when it comes to the amount of creations. Nowadays bizarre ideas like mobile networks in different planets aren’t that far fetched eiher.
It’s going to be an interesting ride, for sure. However, we must be also conscious about the planet we’re currently living in. Even though there are efforts to make this planet greener, there is a lot left to do.
