It Happened! Elon Musk Finally Reveals Artificial Gravity Starship 2021!

DhXN2KMM_tE
For the first time in the history of humanity, we stand a good chance of walking on the surface of Mars! And this is thanks to the dogged ambition of Elon Musk. The billionaire is building a mighty spacecraft, the Starship, that will take volunteers across the vast distance between Earth and Mars!

However, since the trip will take months in deep space, Musk's company, SpaceX, has to find a way to protect the travelers from the effect of microgravity during the duration of the journey! This is why SpaceX has come up with an artificial gravity Starship! What is this spacecraft, and how does it work? Join us as we explore SpaceX's insane artificial gravity Starship! Regardless of whether you think attempting to go to Mars is foolhardy or is not going to work, Musk is forging ahead with his plans to take people from the Earth to Mars to live there permanently. This is the main reason he is building the Starship, the space rocket that promises to be the most powerful ever built! It will be configurable for carrying humans or cargo.

The Starship is unique in several aspects. It is capable of lifting more than 100 tons to orbit, which is necessary given that lots of tons of cargo have to go ahead of the colonizers! This will contain systems that will keep them alive. Remember, Mars is a very harsh environment, and special provisions have to be made. Musk has to supply water, food, materials for constructing shelters, machinery for making rocket fuel, and all the works! SpaceX has designed the Starship to consist of an upper and lower stage. At the point of separation, the lower stage or the Super Heavy booster will return to Earth while the Ship will proceed to Mars after refueling in orbit. To save on cost, both stages of the Starship are completely reusable. The booster returns to the land and is quickly checked out and prepped for the next flight. It will depend on about 30 Raptor engines for propulsion. The Raptor engines are designed and developed by SpaceX. The upper stage will also re-enter the Earth after each mission, with heat resistant tiles protecting it from getting damaged by the heat produced.

SpaceX plans to make about a thousand of these starships and launch at least three per day. This will allow Musk to quickly reach his goal of one million people on Mars! Of course, the Starship is not meant for Mars trips alone. NASA plans to use the Starship in its next mission to the moon. The spacecraft will drop the astronauts on the moon's surface and return them to orbit after they complete their missions. As a cargo carrier, the Starship is relatively simple to design. However, when the Starship is meant to transport people, some complications begin to show up.

For shorter trips, like to the moon, SpaceX won't have to worry about because this will last several days. However, going from Earth to Mars takes months and exposes the passengers to harmful radiation in the harsh environment that the Starship has to pass. But of course, this particular problem can be fixed by putting shields on the Starship. But one other problem that is not easily solved is gravity. It is an issue that affects astronauts that are not going as far as Mars because they have to keep to a strict regimen of exercise while aboard the International Space Station. Even this is not always enough, as returning astronauts sometimes have to be stretchered out of their spacecraft when they return from months-long missions.

Instead of artificial gravity, why not anti-gravity? I find it difficult to believe that someone like Musk, with his almost infinite resources and wealth, doesn't have access to, or at least knowledge of, the "good stuff" kept from us peasants under lock and key.

It's bad enough that after all these decades we're still sending astronauts to space on the top of essentially a very large firework. It's kind of depressing that other than computer power, space technology has hardly moved forward an inch in 70 years.

There's also this which is interesting. Is Musk merely a puppet being used to usher in this new space race?

Elon Musk: His Mars mission was predicted back in 1953

From Pia Karim on June 16, 2021 at 7:45 p.m.

In October 2020, Elon Musk, boss and co-founder of SpaceX , announced that humans will set foot on Mars in 2024. He firmly believes that the only way to save the future of the earth is to have people colonize space.

https://projectavalon.net/forum4/image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mN8/B8AAssB5CY77SMAAAAASUVORK5CYII=
What Elon Musk didn't know, however, is that his plan was already foreseen. It wasn't in the stars, but on paper. In 1953, a book was published that predicted Elon Musk's plans to bring humans to Mars.


An accident?

On December 30, 2020 Elon Musk will post a famous sentence from the horror comedy Frankenstein Junior with Mel Brooks on Twitter :
Destiny, destiny. I am not escaping it. Even if it's just fiction, the quote refers to the idea of ​​predestination, according to which the life of every human being is already predetermined, be it by a god or by genetics. Twitter user Toby Li replies to this quote:
Speaking of fate, did you know that Von Braun's 1953 book "Mars Project" speaks of a certain Elon who will bring people to Mars? That's pretty crazy. We're talking about Mars Project: A Technical Tale by the author Wernher Von Braun, a German-American rocket engineer and pioneer of rocket weapons.


Elon Musk: the ruler of Mars

It is a special kind of non-fiction book, because Von Braun explains to ordinary readers in a narrative way what a trip to Mars would look like.
However, what Toby Li wrote is not entirely true, because the book does not say that someone named Elon will bring the people to Mars, but that the leadership position is called "Elon". Pranay Pathole clarifies this on Twitter and immediately delivers the said passage from the book:

The Mars government is headed by ten men, whose chief is directly elected for five years and named "Elon". Two chambers of parliament ensure justice and are guided by the Elon and his cabinet.
In the meantime, Elon Musk describes himself on Twitter as the ruler of Mars - let's see if his visions really come true.

A post about the secret space program mentioned that their craft already was capable of flying from Earth to Mars in a relatively short period of time. So, what is the game here, is it to try to hide up the capability of craft already traveling at intergalactic speeds using antigravity? Or, how about this: We are told everything in the Universe is moving relative to everything else in organized fashion. If you have a craft repelling from Earth using antigravity methods, when it gets far enough from the ground, it can exercise directional control independent of the directions being taken by Earth and any celestial bodies. Therefore, just for purposes of visualizing relative motions and their possible outcomes, the Universe is going Right and you can disengage the craft from the solid celestial body and send it going Left, the speeds generated in separating the craft from the celestial body are accelerated. Now we know that the speeds and directions of celestial bodies are more complicated than the simple example. A computer on the craft can automatically calculate the directional movements which would quickly cover distances in space. As for cutting out the sensations of change of motion that we experience on Earth, these space craft automatically cut out that sensation, called G's. Therefore, no orbiting ring is required to create the sensation of gravity. Because rockets are unidirectional, they are now passe.

So, the multi-national corporations are giving billionaire boy, the best of the lot by far-even if on a very short real tech tether, the go ahead to begin the cheaper thrills marathon. A little more, just a little bit more inventive. The new dirigible. The new airship. Don't mention the real science whatever you do, Elon.

I can say without reservation that i would feel insulted if asked to take a short, minutes only trip on a Space X or Blue Origin flight, or asked to take an unnecessarily long, primitively fueled spacecraft to Mars, with or without artificial tasting gravity. I'm not impressed at all. By the way, who paid for all of the real craft we had Ben Rich making for all of those years. Yes, Skunk Works was indeed a factual and scientifically based name for all that humanity has paid for, for all of these years.

With decades of anti-grav craft available, there are boat loads of humans sayin' "Been there. Done that. Come to think about it, on my last assignment there they had improved the food so much, we had tacos with guacamole, sauteed onions and cheese." Talk about very expensive and very cheap thrills.

[East Sun]

Musk should definitely be on the FIRST trip to Mars.
Anyone qualified who would become a guineapig with Musk not
going on first trip would be crazy just to be a first on Mars.

[Sunny-side-up]

like so many others shown in history, musk is being allowed to be the head of the permitted, the allowed.

Not what is.

I'm glad it seems like Mr Musk is the real thing as far as pushing space tech etc. but the title of this post dose not seem right to me.
It's suggestive that Mr Musk has introduced new tech, I.E anti gravity, he hasn't

What he is showing is a ship with a gravity producing environment, old tech.

Like his idea's and ships so far though

Elon Musk & NASA's Terrifying NEW Discovery on Neptune Changes Everything!

MBBQ-3nsLhAThe National Aeronautics and Space Administration is one of the most iconic agencies in the US. It has been responsible for many of American finer moments with its research and achievements. With one of the biggest budgets for any agency in the US, NASA is equipped to fund many high-power investigations! However, by teaming up with Elon Musk, NASA has unlocked many more opportunities! The latest example is the discovery on planet Neptune! What has Musk and NASA discovered on Neptune, and how does it affect you? Join us to explore Elon Musk and NASA's insane new discovery on Neptune that changes everything!

What is the longest distance you have ever traveled? If you had moved from one continent to another, most probably in an aircraft, you could have covered thousands of miles! That is child's play compared with Voyager 2's journey! Moving in the opposite direction to its twin, the Voyager 1, the spacecraft reached planet Neptune in 1989, 12 years after it took off from Earth! It was, and still is, on a journey through the solar system! What it discovered on Neptune was mind blowing! The spacecraft beamed the first images of the planet's rings, but there was another discovery; a massive and violent storm! NASA scientists were not expecting the storm Voyager 2 sent the pictures of! It was spotted in the southern hemisphere, appearing as a counter-clockwise wind of up to 1,500 miles per hour or 2,414 kilometers per hour! It was the strongest ever recorded! Astronomers called it the Great Dark Spot. Five years later, it had gone by the time the Hubble Space Telescope looked at the planet.

This led to lots of questions about why the winds were so strong! The strong wind, however, was not the only thing puzzling scientists about Neptune! Its temperature was also a mystery. Voyager 2 revealed that Neptune is warmer than Uranus, despite being farther from the sun. The conventional wisdom was that the farther you go from the sun in the galaxy, the colder it became! Yet Neptune had more heat than Uranus! The question is, where is the heat on Neptune coming from? As physicist Brian Cox discussed in his BBC documentary, The Planets: "The source of this extra heat remains a mystery."

However, the bigger puzzle was whether the two usual behaviors, that is, the strong wind and the elevated temperature, were in any way tied! Some scientists even speculated that unraveling one mystery would explain the other! But how would this be achieved? Measuring Neptune's temperature, however, is not so straightforward! For example, on Earth, you can take measurements on the solid surface and calculate the global average. That is not possible on Mars, which is made up of gases.

So if you must take a temperature of Neptune, it has to be at an altitude. This is where you need to make another decision; at what altitude will you take the measurement? There is something else about the temperature measurement taken by the Voyager 2! Obviously, it took the temperature from the outermost layer. At that point, the temperature of Neptune is not so much higher than that of Uranus.

But since Neptune receives less solar illumination because it's farther from the sun, this shouldn't be the case. What this similarity in temperature suggests is that Neptune is warmer in terms of how much heat it emits in comparison to the amount of heat it absorbs from the sun. According to Anthony Del Genio of the NASA Goddard Institute for Space Studies, "Voyager's measurements show Neptune emits more than twice as much heat as it absorbs from the sun, while Uranus does not." This doesn't make Neptune unusual, though. In fact, it makes Uranus weird because other planets like Jupiter and Saturn also emit more heat than they absorb from the sun! As stated earlier, the progression of temperature as you go farther away from the sun shows Jupiter to be the warmest of the gas giants, Saturn next, then Neptune. Uranus is the one that is out of place. Del Genio explained the oddity further: "Yet that unusual result is associated with the fact that Uranus does not have a significant internal heat source."

In other words, Neptune is finding a way to warm itself up to the level of Uranus, while the latter is unable to generate any extra heat other than that gleaned from the sun! But just what is an internal heat source? In simple terms, it is heat left over from the birth of the solar system when these planets were formed. The heat contracts out of the primitive solar nebula, forming an effect known as the Kelvin-Helmholtz contraction.

The extra heat source on Neptune, Jupiter, and Saturn is primarily due to gravitational contraction. As the planet slowly gravitationally contracts, the material falling inward changes its potential energy into thermal energy, which is then released upwards out of the planet. For Uranus not to have such a heat source, something must have happened to it! So, the question is, why does Neptune produce heat internally, but Uranus does not?

Musk outlines Starship progress towards self-sustaining Mars city

https://www.nasaspaceflight.com/wp-content/uploads/2022/02/NSF-2022-02-11-21-22-55-037-1170x774.jpg (https://www.nasaspaceflight.com/wp-content/uploads/2022/02/NSF-2022-02-11-21-22-55-037.jpg)
SpaceX Chief Designer Elon Musk has provided the first overview for the Starship Program since 2019, announcing a roadmap towards building a self-sustaining city on Mars.

With Starship, a rapid and completely reusable super heavy-lift launch vehicle, as the focal point, Musk hopes to achieve the goal of an orbital test launch this year, followed by a multitude of various missions from a range of launch site options, from Starbase to KSC, and even ocean launch platforms.


The Reason For Starship:

Under the gaze of the full-stack Booster 4 (https://www.nasaspaceflight.com/?s=Booster+4) and Ship 20 (https://www.nasaspaceflight.com/?s=Ship%2B20) Starship, the progress made since Musk’s previous presentation was self-evident.

During that 2019 update, Musk had the Mk1 Starship prototype peering over his shoulder, in the middle of a small production site and just down the road from what was just the Suborbital Launch Site, occupied by Starhopper (https://www.nasaspaceflight.com/?s=Starhopper) – at the time the star of the Starbase show. “A lot has happened since then,” said Musk in his opening remarks. The latest update came from the Orbital Launch Site, lit up for the presentation, visually adding additional contrast to the previous event. With the successful – and speedy – stacking of Ship 20 atop Booster 4 via the Mechazilla Chopsticks (https://www.nasaspaceflight.com/?s=Chopsticks), the overview was backdropped by a full-stack Starship.

The driving force for the Starship program is fostered by Musk’s ambition to make life multi-planetary. This point was emphasized at the very opening of the presentation, with the holy grail of a rapidly and fully reusable launch vehicle.
That was proofed via the mass to orbit capability of Starship. While Elon cited the total mass launched to orbit by any nation thus far as 15,517 tons, Starship can lift 15,500t to orbit after one year of three Starship launches per week.

This rapidly increases based on launch cadence to the target of 1,000,000t that Musk believes is required to create a self-sustaining city on Mars.

https://www.nasaspaceflight.com/wp-content/uploads/2009/06/NSF-2022-02-11-20-17-06-406.jpgSpaceX render of a city on Mars.


The goal relates to the limited opportunities for ideal Mars transit windows every two years and the amount of material needed to ensure a city on Mars is independent of Earth, should issues arise with the supply line.
For the first time in the planet’s history, such a goal is now a reality via Starship – with a payload capacity of 100-150t, dependent on the orbit, and a capacity to Mars of roughly 100t. Elon noted that this could eventually rise to 200t with orbital refilling.

https://www.nasaspaceflight.com/wp-content/uploads/2022/02/NSF-2022-02-11-21-36-35-484.jpg

Orbital Refilling with Starship – SpaceX Render

The rapid reuse of the vehicle will target reuse of the Ship every six hours, with the Booster theoretically recycled for launch every hour.


Raptor Evolution:

During the test phase, both the Booster and the Ship have continued to evolve. The Ship will move to nine engines, while the Booster will soon sport 33 engines – the maximum number of engines based on the vehicle’s diameter.

The engine itself is evolving, with Raptor 2 now deep into testing at SpaceX’s McGregor test site (https://www.nasaspaceflight.com/2022/01/raptor-2-starbase-update/).

Raptor 1 already sported 185t of thrust. However, with Raptor 2, that increases to 230t. Raptor 2 is also “greatly simplified while increasing thrust. Half the cost at more thrust,” Musk added. The current peak thrust R2 operated at is 247 tons, so SpaceX is confident 250t will be achieved, which is “obviously essential to making SS work.”
The visual changes between Raptor v1 and v2 are apparent, with less cabling and plumbing around the engine.

While it’s easily visible around the entire engine, the turbopump appears to have been shrunk in size, and the plumbing has been consolidated.

Raptor 2 SN5 appears to be a Raptor Boost engine, which means it lacks the ability to gimbal or steer and cannot throttle as low as Raptor Center engines.
This engine is far more than just a step up from V1. It was a complete redesign; everything from turbomachinery to chamber nozzle to its electronics has been redesigned. This allowed items to be deleted and consolidated while the turbopumps are more robust.

Citing his dislike of flanges, many have now been converted to welds. “At high pressures and cryogenic temps flanges are a nightmare,” Musk noted. “700-800 bar in places, 11000psi, going to welded from flanges is helpful.”

Musk also noted that the preburner controllers have moved to boxes rather than being all over the engine. This allows future changes to the point where Raptor will not need a shroud – this will reduce its mass and stop being “a pain in the ass, especially for gimbaling engines,” per Musk.

“With more deletion and integration, the engine will be flameproof, and losing shrouds is a good mass saving. Probably can operate at 330 bar sustained in the main chamber without having the pre burner pressure be too high.”

This will remove choke points, resulting in less pressure loss.
Raptor testing has been proceeding well at SpaceX McGregor, including the observation of Serial Number 10 (https://www.nasaspaceflight.com/2022/02/booster-4-ship-20-pair-starship-update/), via photos from NSF’s Gary Blair (L2 McGregor (https://forum.nasaspaceflight.com/index.php?topic=47345.0)). That engine was shown in action during the presentation.

The remaining challenge is mitigating against the engine chamber melting.
“The only remaining issue that we’re aware of is melting the chamber, that thing really wants to melt, it’s got like on the order of a gigawatt of heat, so it’s pretty hot, like a gigawatt is what a nuclear power plant produces, so it really desperately is trying to melt at any point in time,” Musk noted, in response to Tim Dodd, who only recently released a video on how engines avoid melting (https://www.youtube.com/watch?v=he_BL6Q5u1Y).

“So we’re flowing an immense amount of cryogenic fuels to cool the chamber and the channels, we have head-end film cooling, we’ve got throat film cooling, and we’re just trying to get the exact sort of balance between head-end film cooling and throat film cooling to not melt the chamber.”

“I think we’re pretty close, we have a couple engines in the stand that have 700 or 800 seconds of operation and several start cycles, so it’s looking positive, but that’s the remaining issue, melting the chamber.”

Addressing the production rate, Musk provided an optimistic overview. With Raptor 2s now undergoing testing at McGregor (https://www.nasaspaceflight.com/?s=McGregor), a new production facility at the site is almost ready.

“We’re scaling up production to get to one a day or better, so apart from melted chambers we’re doing well. We’ve got a lot of pumps, a lot of electronics, a lot of preburner controllers, so just not melting the chamber is very difficult and is kinda the last remaining challenge, but I think we’re very close to solving that.

“The production system has a lot of momentum like we said, next week we’ll probably make five or six Raptor 2s, and I think we’ll be at seven a week or better by next month. These are crazy numbers for rocket engines, by the way.”

McGregor will also be the focal point for testing additional limitation checks on the engines, with Musk hoping Raptor can achieve 330 bar sustained in the main chamber.
“A lot more to go on; we’re also operating a higher chamber pressure; I think over time we can operate it at 330 bar sustained in the main chamber,” he added.

“Without having the preburner pressures be too high by essentially by losing less pressure, there’s like a whole pressure ladder going from the turbopumps and preburners to the main chamber.

“By getting rid of a bunch of the choke points, we can have less pressure loss, and the pumps can effectively produce more pressure in the main chamber with less loss in the secondary systems.”


Launch Sites:

The build-up of the facilities in South Texas has been extraordinary, again evident in the changes since Musk last updated the Starship program from the facility now known as Starbase (https://www.nasaspaceflight.com/?s=Starbase).

It still requires a legislative process, namely an environmental assessment from the FAA (https://www.youtube.com/watch?v=oTiesMAdlU0), to complete before approval for launches can take place, which Musk believes may take another two months.

While the Production Site increases capacity, with a new High Bay being built alongside the existing structure, the launch site gained the primary focus for Musk’s overview.
Citing the impressive Launch Tower – with its Mechazilla system – took only 13 months from design to competition, Musk noted “Stage Zero” is as complex as the Booster or the Ship, emphasizing the successful use of the Tower with the recent stacking of Ship 20 onto Booster 4.

The forward goal is to have two towers at Starbase’s Orbital Launch Site (OLS), although such plans will likely be at the mercy of the ongoing environmental reviews.
Notably, and not just as a backup option, Musk noted that the future launch site at 39A (https://www.nasaspaceflight.com/?s=Starship+39A) has already passed that milestone. In addition, SpaceX and NASA recently confirmed studies are being worked on to potentially add additional launch capability at KSC’s LC-49 (https://www.nasaspaceflight.com/?s=LC-49).

With South Texas and Florida’s Eastern Seaboard the two ideal launch locations, a potential scenario may see Starbase focus on the test launches, – along with operational launches with payloads such as Starlink, while KSC would become the leading launch site. This would map with KSC being the likely launch site for NASA missions such as HLS (Human Landing System) (https://www.nasaspaceflight.com/?s=HLS).

“Starbase, I think, it’s more suited to become our advanced R&D location, so it’s where we would try out new designs and new versions of the rocket, and I think Cape Kennedy would be our main operational launch site,” Musk noted, before referring to the ocean launch platforms, two of which SpaceX has already purchased.

“Then, over time, I think we’re going to have floating spaceports like ocean spaceports, we’ve got these two converted oil rigs that are going to be turned into orbital launch sites, and they can be moved around the world.”

The two platforms currently being converted are Phobos and Deimos (https://www.nasaspaceflight.com/2021/01/spacex-rigs-starship-spaceports/), although very little work has been carried out over recent months. One will gain renewed focus with the installation of its own launch tower by the end of this year.

“Phobos and Deimos thus far have been a relatively low priority; we needed to make the launch site here work; this has been quite a difficult endeavor, so we deprioritized Phobos and Deimos.

“We’re going to take one of them and build at least a catch tower on it and ultimately we’ll, ultimately meaning I don’t know, later this year, build a full launch capability on one of the platforms.
“Hopefully, by the end of this year, we’ll have a launch capability at Cape Kennedy at LC-39A and on one of those platforms as well.”

That first operational platform would allow a template to be formed and the purchase or construction of additional platforms, with Musk adding there “could be quite a few of those.”

“I think most of the launch sites long term will be ocean or sea spaceports, maybe located 20 or 30 miles offshore, and this would allow Starship to connect any cities that are on the ocean or on the sea, and have a high flight rate without disturbing people too much. I think people are willing to have something that’s loud occasionally, but if you want to have it frequently, then it needs to be offshore.”


Operational Missions:

Although Musk correctly prepared Starship fans for a few failures during initial testing, Starlink (https://www.nasaspaceflight.com/?s=Starlink), HLS (https://www.nasaspaceflight.com/?s=HLS), and dearMoon missions (https://www.nasaspaceflight.com/?s=dearmoon) are already on the books once the vehicle passes into its operational phase. There was also a hint at announcements soon to come.

While Starships cargo capability is apparent, the evolution into launching humans will only come after the vehicle has proven itself during those uncrewed launches.
One of the key questions that have been queried over the development of Starship has been its lack of an abort system. Musk addressed that when asked by NSF’s Chris Gebhardt (https://www.nasaspaceflight.com/?s=https://twitter.com/ChrisG_NSF).

“Starship will not have an independent abort system, but I think something that would make sense to have the thrust to weight (TWR) of the Ship be enough that it could take off from the Booster even if the Booster has a failure at the pad level.

“If you can get the TWR of the Ship at sea level above 1, even if something goes wrong with the Booster, the Ship is just going to fly away from the Booster, so that’s something that will be important for carrying people or even high-value cargo to have the Ship have a TWR of greater than one at sea level.

“That would be the nine engine version, and even if you lost one engine, I think you should still be able to do an abort. I think for crewed missions, we’re essentially going to detank the Ship to some degree so that you’d have a launch abort capability even if you lost an engine.”

While Musk had earlier noted that the long-awaited official views of the interior of a crewed Starship are not the current focus of SpaceX’s development of the vehicle, Musk did elaborate on the life support planning.

“From a life support standpoint, we could scale up the life support system in Dragon (https://www.nasaspaceflight.com/?s=Dragon), and that would work for missions that were say a week or two weeks, that would be fine, for missions to Mars, you’d want a life support system that’s renewable, essentially recycling everything in a closed-loop system with close to zero loss to mass.

“So that would be a more advanced system; we’d have to convert the CO2 back into O2 and kinda recycle the waste and stuff. That’s a harder problem, but it’s not an immediate problem. We could certainly scale up Dragon for any kind of missions that are a few weeks long.”

Interestingly, some key questions remained outstanding from the overview, such as if Booster 4 and Ship 20 continue to be the vehicle combination for the orbital velocity flight test and the status of the OLS Tank Farm, which has yet to be used in a LOX/CH4 fueling of a vehicle.

These answers may come from visually following Starbase testing over the weeks to come, with Friday continuing to utilize the full-stack on the Orbital Launch Site ahead of a potential cryo proofing test (https://www.youtube.com/watch?v=mhJRzQsLZGg).

Interesting quote from von Braun’s book. The "president" of the 10-man Mars government is said to reign for 5 years and his name is "Elon”. This name means in itself "Gods" in any old-Semitic language resembling Akkadian/Assyrian. "El” meaning God and "-on" being the "weak plural suffix" making a number of words plural. (This being similar to the Hebrew "Eloh" ("divine being") made plural by the plural suffix "-im".) Typically Babylon is a concatenation of the noun phrase "bab el-on" which means "gate" (of) "gods".

Quite promising name for Mr Musk. ("Musk" itself being the symbol of the attractiveness of the Beloved, being in the first place the Divine. Gods’ musk. Living as yielding to the attraction of gods...

(Mars to begin with – or to end up on where it all began...))

Even Elon Musk says oil and gas production needs to be expanded, according to author Michael Shellenberger. “The bottom line is we are in the worst energy crisis since 1973,” Mr Shellenberger told Sky News Australia. “That crisis is fundamentally of inadequate supplies.”

I don’t see why I need to sit out weaponised boyhood’s obsession with teKKnahlahdjee parading its newest killing-kite-to-be before I get a glimp of a starship built by The Odorant of the Gods, John. So I jumped out of the drone (in its two meanings) at time 6.04.

I missed something!
