If there's this, then there is gold and platinum and whatever other metals we need.


Two Quintillion Tons of Metal or Dense Oxides Found on the Moon



If this is a massive metal resource then it would make lunar colonization and the industrial development of space far easier.

It could be a pile of metal five times larger than the Big Island of Hawaii.

It was found by analyzing measurements of subtle changes in the strength of gravity around the Moon, researchers analyzed data from spacecrafts used for the National Aeronautics and Space Administration (NASA) Gravity Recovery and Interior Laboratory (GRAIL) mission.

Computer simulations of large asteroid impacts suggest that, under the right conditions, an iron-nickel core of an asteroid may be dispersed into the upper mantle (the layer between the Moon's crust and core) during an impact.

"We did the math and showed that a sufficiently dispersed core of the asteroid that made the impact could remain suspended in the Moon's mantle until the present day, rather than sinking to the Moon's core," James said.

Another possibility is that the large mass might be a concentration of dense oxides associated with the last stage of lunar magma ocean solidification.






And once we get the metals mined, we will be able to build this (below) to go to the stars.


Game Changing Direct Drive Fusion Propulsion Progress



The truly game-changing levels of thrust and power in a modestly sized package could integrate with our current launch infrastructure while radically expanding the science capability of these missions. NIAC grants require that a technology be studied in the context of a specific mission. The mission context is the delivery of a Pluto orbiter with a lander, which cannot be done with any other technology. Direct Fusion Drive (DFD) provides moderate thrust to allow for reasonable transit times to Pluto while delivering substantial mass to orbit: 1000 kg delivered in four years using 5 N constant thrust.

Since DFD provides power as well as propulsion in one integrated device, it will also provide as much as 1 MW of useful electrical power to the payloads upon arrival. This enables high-bandwidth optical communication, powering of the lander from orbit, and radically expanded options for instrument design.

The Princeton Field-Reversed Configuration (PFRC), which is a steady-state fusion reactor concept with heating via rotating magnetic fields. A thrust model of the reactor is presented that is based on a fluid code modeling the exchange of energy in the plasma surrounding the reactor.

If I were Trump, I would announce re-start of the Moon (and/or Mars) program on the 50th anniversary of the Moon landing.  

It would be a political jackpot.  He can even plagiarize Kennedy's speech, nobody will care.  He will go in history as the greatest president of all time.  I think he is going to do it.
Trump has already done this. He's directed NASA to go back to the Moon. It is ONLY because the hate the media has for him that they do not / have not reported this.

But he is more of a doer than a talker, so let's see them minimize the issue when our men are boots on the ground.

Much easier though, and essentially the same, would be an Apollo 8 - Apollo 10 style mission, circle the Moon and return home. AFAIK all the parts and pieces are available for this, but we don't have a modern LEM built and ready to fly (or men trained to use it).

....How accurate are you when you eyeball the distance across your room in the funny farm? If you are anywhere close to the sun, you should have your room down to the thousandth of an inch.

The famous aviator Wiley Post, 1920ish, had lost one eye when young. He trained to estimate distances very accurately with one eye. Hence, with no triangulation. He would often win wagers in bars this way. It enabled him to pass the Airman's exam, which required good vision.

So I'll let that issue pass.

However, you are correct in that NotBat has not shown the total of the triangulation issue. There are several issues.

(A) How much does the Moon change in diameter, from the Supermoon to the minima, and why?

I'll need to read up on supermoons; I'm sure somebody has documented and published those values. As for the why I'll say it's atmospheric refraction unless there's other greater factors I'm not considering.
Supermoon is simply a full moon at the moon’s “perihelion” with the earth.

What does it mean, if an object in the sky periodically, and predictably, changes in diameter?

I'd say it means it has a cycle.
But what is that cycle? It’s the cycle of the orbit of “perihelion” and “aphelion” with relation to the object it revolves around.

(B) From where might we stand, say in a couple of places, to measure the Sun and Moon over the course of a year?

This would be to find their distance from the Earth.

Anywhere they're visible in your field of view, preferably with a high angle to minimize atmospheric refraction.
The sun: directly under it at opposite times of the year.
The moon: Same spot when the moon is on opposite horizons.


(C) We commonly measure the height of mountains on the Moon, and the depth of craters, using a form of simple triangulation. Measuring the spreading of the shadows as the Moon moves to a crescent.

Notbat, care to comment?

Who is "we"? Your "team" (an anagram for meat) is probably making assumptions about the distances involved.
The community of professional astronomers, although amateurs can do it, as well.

(D) Given that the terminator line moves precisely across the lunar surface over the course of a lunar day (27+ Earth days) and we measure heights on the Moon of objects as they approach that terminator, geometrically this is only possible if the Moon is a sphere like object.

NotBat claims the Moon is just a bright light?

... projected off of a concave mirror.
Impossible, because, even though the moon has phases that might correspond with seeing a mirror from its edge, we can often see the full circle of the moon, dimly, during its phases. This being the case, the full circle of the moon is always there. But we would see it as a “cat-eye” if we were looking at a mirror on edge.

(E) A lunar eclipse is when the Earth occludes the Sun, as viewed from the Moon.

You're making an assumption, what if the eclipse is a filter passing in between the Moon's projection?
Inventing more stuff, eh? If there were a filter, it would be visible at other times. I mean, maybe there is a glass dome between the earth and the steel dome, and the glass gets heavy cataracts exactly at the eclipse times.

We will consider the trig involved in this, along with a quite interesting topic, after NotBat answers the above questions and issues. This topic is how we can predict lunar eclipses.

I'll have to check and confirm this but I've read that modern astronomers still use the old geocentric flat earth equations to make lunar eclipse predictions; it aint broke so they never fixed it.
It’s called confirmation of correct methods and figures.

Any scientific theory is affirmed if it predicts correctly. We have a model of elliptical orbiting masses in space, which we can use to accurately predict many things. All on the basis of a synergistic development of math, and orbital mechanics, over three thousand years. But you reject all of that.

No problem. We can step through the fundamentals.

There are no heavy balls floating above us being held up by a magical force a butterfly can overcome by flapping its wings. The lights in the sky are just that, lights in sky.
That’s because the biggest looking ball is below our feet. It looks the biggest, because of how far away the others are from us. However, not all asteroids are balls. A combination of gravity and centrifugal force holds it all up there... not magic.

Yes, I think we did land on the moon. But I also think it is a possibility, that some of what we saw, might have been produced. But not because they didn't do it, but because they didn't want to show us everything they really saw up there, and all the things that were really going on.

Once we got up there it seemed like everything changed. The Nation's attitude changed from, " Let's race!. The space race!.".to "Let's back off."
"Let's go back to just orbiting and make an international space station."  Why?
Politics. Democrats kill space programs. Time after time.

Maybe something up there said, "Back off. Go and tell your people you did it, and don't say a word about anything that is going on up here. Go back to your own neighborhood, orbiting and doing space experiments on your space station and we will help you here and there, but don't come back here...too often...or for a long time.

Maybe. Impossible to disprove. But we have gone back, again and agin, although with robots. We've mapped the entire moon's surface down to everything the size of a football.

Our earth was in chaos before the moon was in place. According to some theories the moon stabilized our earth made it habitable and keeps it from wobbling too much.
The moon does act sort of like an outrigger on a canoe. Otherwise, like Uranus, a planet could rotate 90 degrees to the plane of the solar system.

Ok, don't throw me into the same basket for the believers of conspiracy theories.

I believe Earth is NOT flat. I don't believe there are aliens in Area 51.

But this question is factually not very convincing and it is, did we actually land on moon in 1969.

There are many compelling evidences, facts etc that proves that indeed we landed on moon.

But even in 21st century where there an accident with Kalpana Chawla who merely went to space and came back, it sounds too good to be true that in 1969, we landed on the moon which is around 300000 kms or 186000 miles from the Earth with those time of technologies and successfully came back. Remember, the first apple computer was launched in 1976.

I'm not saying we didn't, I'm just saying that it's not really a question that can be debunked like other theories which says Earth is flat.

Yes, I think we did land on the moon. But I also think it is a possibility, that some of what we saw, might have been produced. But not because they didn't do it, but because they didn't want to show us everything they really saw up there, and all the things that were really going on.

Go back to your own neighborhood, orbiting and doing space experiments on your space station and we will help you here and there, but don't come back here...too often...or for a long time.

Also the stories of the moon ringing like a bell, and being hollow sound reasonable to me. Another whole thread.

Our earth was in chaos before the moon was in place. According to some theories the moon stabilized our earth made it habitable and keeps it from wobbling to much.

^^^ You're a clown using pipul to win an argument with intellectual dishonestly. Every eye has an angular resolution limit or distance and I'm using that distance to measure other objects. You response (you fucking clown) is to conflate the maximum distance the eye (any eye or camera) can see with with the concept that the human eye has limited abilities thus can't be used.

This like telling somebody you're having guests for dinner then killing and eating them when they arrive for supper. You had "guests for dinner" and everybody you told about having "guests for dinner" believes that you met with some people and shared a meal together.

I'm simply agreeing with you. If that makes me a clown, you are worse than a joker.

Since "every eye has an angular resolution limit or distance," there is a limit to which you can trust measurements made by the simple eye. Isn't that what you are saying? And when you say "the human eye has limited abilities thus can't be used," aren't you simply confirming it?

So, what do you do when you want to measure things more exactly?

- If you want to measure the length of your car, you might use a tape measure. You can eyeball it and guess. But using a tape measure is way more accurate.

- If you want to measure the length of a table, you might use a yardstick or a ruler. You can eyeball it and guess. But using a tape measure or ruler is way more accurate.

- If you want to know the height of a tall building, you triangulate shadows with a smaller object that you know the height of. You can eyeball it and guess. But using triangulation with shadows is way more accurate.

But guess what triangulation is. It's measuring the size or distance of objects using 2 known measurements, of 3 possible measurements, to calculate the third. You can't triangulate distance or size by knowing only the angle. Or can you literally show us how?... since you agree that eyeballing it (even with a sextant) doesn't produce accurate measurements.

Come on, now. Don't keep us in suspense. Show us the calc you are using. Quit telling us that eyes have their limitation... or that they don't, if that is what you are trying to say. We all know this and agree with you on it. So, show us the calc that proves what the eyes are too limited to prove.

Besides, inviting forum members to post in YOUR flat earth thread, is like inviting guests for dinner then killing and eating them when they arrive for supper.

Looks like our next moon shot will be centrifugal. However, we are the beginning of this. But it shouldn't take long to develop.


Secretive Startup SpinLaunch Gets 1st Launch Contract for US Military



The secretive startup SpinLaunch, which aims to fling satellites into space without a traditional launch pad, has just secured its first launch contract.

In a statement today (June 19), SpinLaunch announced that it has received a "launch prototype contract" from the U.S. Department of Defense under a deal arranged by the Defense Innovation Unit. The Long Beach, California-based company aims to launch its first test flights in early 2020 from Spaceport America in New Mexico.

SpinLaunch is developing a "kinetic energy-based launch system" that accelerates a small payload-carrying booster to hypersonic speeds with a spinning system on the ground. A chemical rocket would kick in once the payload has been launched from the ground system.

An illustration released with the announcement depicted a SpinLaunch booster attached to the arm of what appeared to be a centrifuge.

@Spendulus,

   NASA states in their documentation on their space sextant that an astronaut has to re-calibrate it every day by spotting a star. However when asked at the press conference after they returned, the Apollo 11 astronauts claimed they didn't recall seeing any stars on their journey to the Moon.

How do you reconcile this discrepancy?

This is well answered, in the past by someone commenting on the lying cunt Apollo Deniers.

https://answers.yahoo.com/question/index?qid=20080427113125AAw5ntS

I still feel compelled to give warning of our unfortunate tendency to take things out of context and the even more distressing one of swallowing the whole cake of misinformation just because it has pretty sprinkles of truth on top. It's a common tactic of prosecuting attorneys, smear campaigns and corrupt governments. I would worry more about the f...ing bakers in this case....and their motives.

When Collins said he couldn't see any stars, he was referring SPECIFICALLY to when they were photographing the solar corona and not for the entire mission.They used star charts along with their navigation tools during their trip and spotted stars with it.


I have studied many of the Apollo transcripts and am familiar with their method of use of the sextant (and a small star sighting telescope) for navigation.

@BADecker,

   The maximum distance the eye can see (angular resolution limit) can be used to measure objects, so I'm not measuring an objects size and distance using only degrees like you claim.


This is why we depend on things other than the eye alone for distant observations. We use telescopes, trig, calculus, laser rangefinders, satellites, etc., because these things bring the measurements down to the eye, where the eye can see them accurately.

Since, as you said, the eye has resolution limits, the eye can't be depended upon. That's why we use other tools, even the sextant. But even the sextant won't work to show distance or size without at least one other measurement in addition to the degree.

Or do you have non-hazy-eye calc that works better than trig?

Cool
