Video: de eerste kolonies rond een andere ster

Op dit moment is het al grensverleggend om kolonies op Mars te stichten. Deze video gaat over een nog veel gedurfder plan: de mensheid en ander aards leven verspreiden tot ver buiten het Zonnestelsel. Het plan begint met een kolonieschip van 2 kilometer lang dat met tien procent van de lichtsnelheid beweegt.

Fascinerend idee.
Thnx ik houd wel van dat soort docu's!

Hm,

There are two types!

1. Satellites orbiting Earth. They are easy to put in orbits! Just apply a force and send them into orbits from ground. They cannot ever land on Earth ground again. Arianespace does it all the time. Via Airbus NV I am a shareholder. We meet 12 April 2017 at Okura Hotel, Amsterdam, Holland, to discuss it.

2. Spacecrafts going to the Moon, Mars or asteroids. They are all fake! Propaganda. Just to impress stupid people. They cannot orbit anything. They have to start from Earth/LEO/EPO, stop and restart at target (Moon, Mars, asteroid) and return and stop back on Earth and it is not possible. You cannot carry the fuel (energy) with you to do it and ... you are lost anyway. You don't know where you are in 3D space during the trip/trajectory.

To travel in space (like Apollo 11) you have to stop at the target (Moon) and then restart there to continue the trip. But you cannot carry the fuel with you for it. You get too heavy. And you must be able to predict the trajectory of your trip ... but you cannot. The n-body problem. And you cannot re-enter and land on Earth again. You are returning too fast and cannot identify the location, where to start the dip into the atmosphere. I have proven it all at my website, i.e. human space travel is a hoax. Only people suffering from cognitive dissonance cannot accept it. It is sad

The spacecraft arrived in high velocity lunar orbit and then escaped (stopped going round in orbit) from high speed lunar orbit and for that you must apply great (rocket) forces on the spacecraft at the right time, location, duration, amplitude and direction and for that you need fuel and a good steering and navigation system.

Which you didn't have.

You seem to be in some sort of denial.

I asked NASA for calculations and Apollo 11 fuel use, but got no reply.

The 1969 Apollo 11 is a good example why human space travel is not possible. Apollo 11 was 100% science fiction or a Hollywood show.

Hm, sorry. I meant ' It is 100% faked and done in a hollywood studio.


Space shuttle and SpaceX are fake too, I explain at my website.

Atomic weapons are a joke!

Manne Siegbahn was Swedish Nobel prize winner physics 1924 and created his own laboratory at Stockholm. Manne was a good friend of my grandfather, their children knew each other and I was a friend of one grandson J living at Manne's house say 1960-64.

As I was and am very intelligent, I considered physics as a career 1964 and mentioned it to Manne. Career? Low paid teacher jobs, few jobs in industry according Manne. Only idiots design nuclear weapons and rockets to go into space in Sweden! Look at the physicists at the Royal Institute of Technology, Sthlm, doing that! All eggheads! Do something else, Manne indicated to me.

Later I found out that Manne had been asked by the government to build a Swedish a-bomb 1945 and agreed ... subject to all being public. So Manne didn't get the job as it was just nonsense propaganda based on secret lies.
He had his own laboratory and was his own boss but got $1M from Rockefeller to shut up. Niels Bohr was another friend of the family and had assisted building the fake US bomb in New Mexico, 1943/5.

Poor Niels was considered a war criminal by some of my family. Imagine assisting building a thing that in a FLASH that lasts nano-seconds kills 10 000's of onnocent, civilian human beings. And Niels could never explain how the famous FLASH was triggered! Suddenly compressing metal to double density? If he had suggested it 1945/6 he would have been considered a fool! No, Niels was just part of the hoax.

He learnt to ski in New Mexico, it was about all.
And in the end he could never describe what a uranium atom was and what happened when it fissioned (disovered by Otto Hahn 1938).
Or why it would produce a mushroom cloud.

Fission is just an uranium metal atom splitting in two parts releasing neutrons and pure energy. Fission must be moderated to do fission. Without moderation the metal atoms just melt and the fission stops.
That a big block of of pure metal uranium can fission and create a FLASH and a mushroom cloud are just stupid propaganda! Invented by FDR and Stalin 1942/5. Both sick persons.

But plenty sick people carry on the lies and the propaganda today. It is big biz.

By chance I met 1999 a person that had built Stalin's a-bombs 1946-1958 using uranium produced by Wismut AG in the Soviet occupied zone of Germany. But Wismut AG didn't produce any uranium at all! It was just propaganda to enable Stalin to announce that his bomb produced a FLASH and mushroom cloud April 1949. It was just communist propaganda. Stalin (and USSR) never had any a-bombs!

Just check a sample of Wismut AG uranium ore today! It is pechblende that contains 0.02% uranium oxide. The 99.98% rest is just rocks of various kind, granite, quartz, stone. You couldn't build an a-bomb or anything with it.

The speed after trans-Earth injection was maybe 2 640 m/s. But in what directions? Everything is unclear. The Moon was at this time still orbiting around the Earth at 1 023 m/s speed, so one way or another the CSM had to reduce that tangential speed in Moon orbit to 0. It would appear they got away from behind or aft side the Moon into the radial course towards Earth, while the Moon continued its circular, orbital course around Earth.
Who knows? Evidently the CSM had to reduce the orbital/circular speed orbiting Earth at Moon altitude to 0 and just get a radial speed away from Moon towards location X in space and location B in orbit around Earth.

It is quite complicated to navigate in space, when the islands or moons are moving all the time, and frankly speaking I do not understand how it is done in detail. Only 3D velocity records using Sun (fixed) as base and none are available.

I sail ships, and always know my location with radar, triangulation and sextant. Also, ships sail on a 2D water surface, space craft is in 3D space! How the Apollo space craft knew its location in 3D space is unknown! I also have lots of good woman, plenty of good food and plenty sex. How the astronauts did this is unknown.

The distance travelled during the 150 seconds trans-Earth injection - you have to get out of orbit around the Moon at exactly the right moment and location A and into a radial trajectory towards location X and then Earth overcoming Moon gravity force - was only 292 500 meter (assuming Moon didn't move but during 150 seconds the Moon evidently displaced 153 450 meters).


You probably were at same altitude 115 000 m during the maneuver, but who knows and cares? During this time the Moon and Apollo 11 moved 365 722 meter sideways which you had to consider one way or another. If you had directed your rocket engine in the wrong direction, you would not have been in orbit around the Moon but going astray or crashed. Note that Apollo 11 has no fuel reserves or redundancy. One error and you are finished!

The conversation of the asstroholes during the 6 minutes lunar orbit insertion, LOI, burn between 75 hrs 50 minutes and 75 hrs 56 minutes of the flight does not reveal anything dramatic ... except that they can see the Moon while braking backwards with the LM at the end of the spacecraft.

How was it possible? Were the three (crazy?) assholes aboard piloting the spacecraft manually with compass/chart pushing the brake button or pedal in the process looking out through the window like on an airplane? How did they know what was up/down/right/left and the directions of velocity and the force.

There is no atmosphere on the Moon to diffuse the light. Everything directly exposed to the Sun should be bright white = light reflected. And everything not directly exposed to the Sun should be pitch black = no light. All photos should be bright white/pitch black. But they aren't.

I confirm there is no atmosphere on the Moon. So there is no diffusion of light there. I also confirm you cannot take pictures on the Moon with a modified Hasselblad camera. It stops functioning, when in the -150°C cold shade and then being exposed to +150°C sunshine. It cracks up.

the only light source on the Moon is the Sun! Neil and Buzz didn't bring any torches or candles with them.

If you make a giant room and suck all the air out, how do you shine a bright light into it? A candle? It will not burn in vacuum. And how do you operate your camera in it? Are you all right? If not, consult a doctor!

light in vaccum - how does it behave, if not in vacuum?

That the two Apollo 11 clowns were taking photos of themselves on the Moon is just a joke. The light was not correct. Their photos should be bitch black or bright white!

Hm, but there was no atmosphere to diffuse the light on the Moon. On the Moon there is only vacuum! Compare Earth where the light from the Sun must pass through 120 000 m of atmosphere full of atoms of all kind before hitting ground and sometimes with clouds in between. It is a big difference, i.e. the light conditions differ. IMO the Apollo 11 pictures were taken in atmosphere ... on Earth. But the photos show a gray surface. Gray surface of the Moon? Isn't it black? Or white? Or yellow? And Buzz used fill cards to light up the shady areas with Moon light 1969.


As far as I am concerned Buzz is an alcoholic that sees everything a bit hazy.

Which I explain at my popular website.

However, the main reason that Apollo 11 never visited the Moon is the fuel! It didn't have enough fuel to do the trip. Another reason is the re-entry and landing in Earth. It is impossible! satellites never return safety. They always burn up!

The problem with your argument is that you seem to believe that color and gray scales of surfaces are caused by diffusion in the atmosphere.

What is wrong with that? If the light from Sun is 100% reflected by anything on the Moon, it is WHITE. And if it is not reflected at all, it is BLACK. It happens in vacuum.

On Earth with atmosphere diffusing the light in all directions, there are all shades between WHITE and BLACK on photos taken, but not on the Moon, where there is vacuum.

Camera settings and film sensitivity doesn't matter at all. Color photo is a little different.

You tell me! I asked people at NAXA but got wrong numbers.
-spam-

Three stages launch vehicle Saturn V with Apollo 11 Command, Service and Lunar landing modules on top. The Apollo CSM had mass 43.8 tons incl. fuel to stop at the Moon and get back to Earth again.

The Saturn V rocket had mass >3 600 tons, most of it fuel. It seems NAXA needed >80 tons of fuel, etc, to get 1 ton of spacecraft with humans to the Moon 1969. It was VERY good. 2015 you need 50 tons of fuel to put 1 ton just in orbit around the Earth. The last use of a Saturn V rocket was the 14 May 1973 launch of Skylab.

Imagine a rocket that 1969 could lift >3 600 tons off the ground and miles into the sky and on to the Moon! Today the rockets are much smaller just putting much smaller satellites into orbit around Earth.

All records how Saturn V worked and all drawings what it looked like were then conveniently lost and some people wonder, if they ever existed ... or if Apollo V was just one empty Hollywood mock-up with some jet engines at bottom and trick film! Then came another strange launch vehicle - the Shuttle - that could not really land on Earth after visiting space! What you saw landing was just another light weight Hollywood mock-up.

2.2 Summary table of Apollo 11 Moon trip

Table starts when the Apollo 11 Control, Service Modules, CSM, and Lunar Module, LM, fitted on the full of fuel Saturn V rockets third stage are already on the way at ~7 500 m/s velocity in Earth orbit put there by the Saturn V rocket's first and second stages (Event #1) ... at about 190 000 m altitude.

The total mass of Apollo 11 CSM + third stage is then 135 699 or 338.692 kg. Nobody seems to know!!! The figure changes. This is the first anomaly of the description of the trip.

At that speed and altitude you go around Earth in about 90 minutes! If you go slower you will soon crash on Earth.

Then the third stage rocket is allegedly fired (Event #3) and the Apollo 11 modules are sent off at ~11 200 m/s velocity in direction Moon about 400 000 km away ... or where the Moon will be three days later. Plenty of fuel was used for getting off the Earth ...3 798 350 liters (or about 3 400+ tons) ... but all carried in separate rocket stages.

How they calculated the location of the Moon, and the time of Stage 3 burn is unknown.

No it's not. What they basically did was aim just ahead of the moon during TLI. They did this in such a way, that if they did nothing during the rest of the flight, the spacecraft would swing past the moon, be slowed down by it's gravitational attraction, and automatically return to earth. This is known as a free return trajectory.
https://en.wikipedia.org/wiki/Free_return_trajectory

In order to get captured by the moons gravity, they would ignite the engine while flying by the moon to slow down enough to stay in orbit.

No it's not. Astronauts could actually use a sextant to navigate in space, using the stars, sun and fixed points on earth for references. They also had an inertial navigation system on board, and could navigate by means of multiple beamed radio waves from earth.

From my terrasse (with some good wine) here on Earth the visible Moon with the Sun shining on it is white - both at night and day. Only one color - white.

I have never seen a gray Moon.

What I see is white sun light being reflected by the Moon, which is then diffused by the atmosphere before reaching me. The Moon then appears generally white and round. If the Moon passes in front of the Sun, when I watch - an eclipse - the Moon will appear to be pitch black. And round.

If you take a picture of the Moon from Earth, you just record Sun light reflected from the Moon towards Earth. This Sun light is then diffused by the Earth atmosphere, e.g. if there is a cloud in the atmosphere, you cannot take a picture of the Moon at all.

If the camera is on the Moon taking pictures, there is no atmosphere diffusing the Sun light and no clouds stopping you taking pictures. The Sun light is pretty intense 14 days every four weeks. It heats up everything it contacts to 150°C. It also lights it up. A lot. On the other hand, where light is not arriving - in the shade - there is no light of course = pitch black.

On Earth it is different. The light has to pass through the atmosphere and through, e.g. clouds. It affects picture taking by camera = photography. All photos allegedly taken on the Moon appear to be taken in an environment with atmosphere. And there is not atmosphere on the Moon. Regardless, it is not possible to fly to and land on the Moon. Rocket science does not allow it.

Sorry, you don't know anything about taking pictures on the Moon. You sound like Buzz Clown.

You really have to study to understand that travel between heavenly bodies is not possible. Only one-way launches of satellites to orbit Earth is possible.

Funny, when I look at the moon or take a picture I see something very different:

Multiple shades of grey there. How do you think that is?
That is because that light has been diffused by Earth's atmosphere.

Hm,

In order to take pictures on the Moon with a conventional camera, you must bring the camera to the Moon, take pictures with it, and then bring the camera back to Earth, open the camera, take out the film and develop it, etc. I think I explain quite well at my web site, why it is not possible.

Start to read about Rocket science, Fundamentals of spaceflight and Human (!) spaceflight and the courses I recommend at the Royal Institute of Technology, KTH, Stockholm, Sweden. Ask the teachers there for assistance. I provide the telephone numbers.


The teachers failed completely to establish a simple trajectory of a spacecraft leaving Earth to land on the Moon and to return again to Earth and land there.
One teacher said he had flown up to the ISS several times, done some EVAs there and then returned and landed on solid Earth ground again but asked for details ... nothing.
I have been told he is an actor just playing his role in the show.

What do you think?

Arianespace puts satellites in high speed high altitude orbits around Earth ... and that is all they can do. It is a one way trip. You cannot stop in or leave orbit and re-enter and land on Earth again.

The satellite has no brakes.

It is not possible for a satellite to leave orbit around Earth to fly off to another heavenly body like the Moon or a planet and land there. You don't know how to apply the extra forces required and you do not have the fuel required for it. You will get lost at once.

It is of course the famous n-body problem with no solution but experts say it is easy anyway.
And if they fly away in the wrong direction, they say it is easy just to stop and change course. But not how to do it. How do you turn 90° in space? Turn a wheel? Fire a rocket? NASA doesn't know how to turn a spacecraft 90° in space!

I think you just didn't understand the explanation ;) Which is perfectly fine, as long as you remain open to information, and don't just dismiss it as fake because it's beyond your current level of comprehension.

Sure they do. It's called a rocket engine. Once you start hitting the atmosphere, drag does the rest.

If you really want to learn more about all of this, I can recommend a very good space simulator video game, called Kerbal Space Program. It can teach you a lot about orbital mechanics, rocket staging, gravity turns, the rocket equation, navigation in the solar system etc etc.

Hm,

There are two types!

1. Satellites orbiting Earth. They are easy to put in orbits! Just apply a force and send them into orbits from ground. They cannot ever land on Earth ground again. Arianespace does it all the time. Via Airbus NV I am a shareholder. We meet 12 April 2017 at Okura Hotel, Amsterdam, Holland, to discuss it.

2. Spacecrafts going to the Moon, Mars or asteroids. They are all fake! Propaganda. Just to impress stupid people. They cannot orbit anything. They have to start from Earth/LEO/EPO, stop and restart at target (Moon, Mars, asteroid) and return and stop back on Earth and it is not possible. You cannot carry the fuel (energy) with you to do it and ... you are lost anyway. You don't know where you are in 3D space during the trip/trajectory.

To travel in space (like Apollo 11) you have to stop at the target (Moon) and then restart there to continue the trip. But you cannot carry the fuel with you for it. You get too heavy. And you must be able to predict the trajectory of your trip ... but you cannot. The n-body problem. And you cannot re-enter and land on Earth again. You are returning too fast and cannot identify the location, where to start the dip into the atmosphere. I have proven it all at my website, i.e. human space travel is a hoax. Only people suffering from cognitive dissonance cannot accept it. It is sad

The spacecraft arrived in high velocity lunar orbit and then escaped (stopped going round in orbit) from high speed lunar orbit and for that you must apply great (rocket) forces on the spacecraft at the right time, location, duration, amplitude and direction and for that you need fuel and a good steering and navigation system.

Which you didn't have.

You seem to be in some sort of denial.

I asked NASA for calculations and Apollo 11 fuel use, but got no reply.

The 1969 Apollo 11 is a good example why human space travel is not possible. Apollo 11 was 100% science fiction or a Hollywood show.
Actually, claiming that anyone who disagrees with you has cognitive dissonance is sad.

The Apollo 11 SM & CM didn't stop at the moon, only the LM did. The SM & CM went into lunar orbit and thus didn't need to break to a complete halt at all.

You do understand that rockets are variable mass systems, don't you? As you burn the fuel, the system gets lighter and needs less force to accelerate it.

You cannot. People much smarter than you can.

N-body solutions can be brute forced.

Again, you can't but people much smarter than you can.

Claiming that it's a hoax doesn't qualify as proof. Prove any laws used for the Apollo program wrong.
Spoiler: You can't.

His assumptions are monumentally contradicted by his cheerful acceptance of satellites in earth orbit who have to know when they are in the correct orbit, and particularly in the case of geostationary satellites that are moved to their final position having started out in a different orbit.

He doesn't think anyone can calculate the required amount of fuel. He doesn't understand how an orbital insertion works. He doesn't know how how a gravity turn works. He doesn't know anything.

Here's a nice link that explains it

http://www.planetary.org/(...)atellite-to-gto.html

and which also includes a very interesting link to here

http://astrogatorsguild.com/

and also

http://www.agi.com/products/

(which he will not understand and will pretend didn't happen. Even though those accurate simulators can fly any Apollo mission perfectly fine.)

Re satellites in Earth orbit they can just ... orbit. No brake, no engine, nothing. Just a satellite orbiting. They cannot go anywhere else than round and round.

Test! Pls answer the following:

Your satellite is in orbit at 300 000 m altitude and with speed 7 000 m/s. It has mass 1 000 kg. You intend to brake to 0 m/s speed and then drop straight down to Earth. Your kinetic energy is of the order 24 500 000 000 J (or Nm). Do you agree?

Thus you have to apply a brake force (N) during a certain time (s).

Say that you apply 24 500 N brake force? It is a lot! Almost 2.5 tonnes force on a 1 tonne satellite.

What is your brake distance from 7 000 to 0 m/s speed?

1 000 000 m? Yes! It is long!

Your average speed while braking is evidently 3 500 m/s, if you brake constantly.

What is then the time for brake from 7 000 to 0 m/s speed? 285.7 s! Yes! Not bad!

Less than 5 minutes.

Now my simple question? How much fuel (kg) is required to apply 24.5 kN force during 5 minutes to stop your satellite?

Isn't it an easy question?

You do understand that something doesn't need to decelerate down to 0 m/s to fall back down to Earth, right?

So if you think the CM needed to do that for re-entry, you're absolutely wrong.
It shows how you know about Apollo and even basic orbital manoeuvres.

Did you ever believe the Apollo landings?
I did up until a few years ago, even though my Grandad, who worked building Merlin V12 engines during WWII and on the prototypes of the RB211 engines in the 1960's told me (in so many words) that the moon landings were bullshit. I still believed the TV rather than my Grandad – something that I will always feel stupid about :) My Grandad thought it was all quite hilarious. But at least I understand the power of indoctrination.
From what I can gather, at the time, there were quite a lot of his colleagues in the aeronautical industry who did not believe the Apollo landing nonsense either.
There was probably a higher proportion of people who didn't believe it at the time than they do now – such is the power of the propaganda.

That is pretty easy to calculate if you know the ISP of the engine, but also completely irrelevant. You also contradict yourself here, first saying a satellite can't go anywhere. The thing is, you don't need to slow down all the way to zero, and sort off fall down. The only thing you need to do is slow down enough that you get low enough for atmospheric drag to become a significant factor. Air resistance (and possibly the ground) will do the rest.

Edit: Also, don't forget that the spacecraft gets lighter and lighter, as propellant is expended. That factor is not taken into account in your rough calculations.

Your satellite is in orbit at 300 000 m altitude and with speed 7 000 m/s around Earth. It has mass 1 000 kg. You intend to brake in orbit to 0 m/s speed and then drop straight down to Earth. Your kinetic energy is of the order 24 500 000 000 J (or Nm). Do you agree? I know it is an unusual maneuver but why not stop in orbit ... and then drop straight down? OK - the braking takes less than 5 minutes so you might start dropping down then. But by applying the brake force a little upwards, you can maintain altitude. OK?

Thus you have to apply a brake force (N) during a certain time (s).

Say that you apply 24 500 N brake force? It is a lot! Almost 2.5 tonnes force on a 1 tonne satellite.

What is your brake distance from 7 000 to 0 m/s speed?

Less than 5 minutes.

Now my simple question? How much fuel (kg) is required to apply 24.5 kN force during 5 minutes to stop your satellite? You use the best rocket engine available.
So what was the answer? A 1 000 kg satellite doing 7 000 m/s speed in LEO/EPO cannot stop in orbit! It is too small and cannot carry the fuel required to produce any brake force to slow down. It can just contine to orbit for ever. Going round and round. You cannot even fly up to it and service it. Why? Beacuse you cannot dock with it.

In order to answer that, we need the ISP of the engine. But as I stated before, it's an completely nonrealistic scenario.

And when you've figured out that number, here you can calculate the answer:

And now you believe youtube videos.

So not much has changed
Yes - the 1969 Apollo press conference is a good one. It's quite sad.
I haven't really watched that many youtube films about it.And i certainly don't beleive everything

David McGowans Wagging the Moon Doggie series is a good read.
A lot of people have doubted the moon landings since the day it happened...a long tme before youtube.
You beleive everything on TV. Whether that is a more reliable source of information or not is a matter of opinion I suppose.

Maybe you should watch more of the educational ones. There are some pretty good ones available.

Je krijgt haast te doen met die gasten. Ik heb de beelden nog eens bekeken, lijkt wel alsof ze van een begrafenis terugkomen en gebukt gaan onder een zware last (leugens vertellen?).
Als je naar de comments kijkt zie je dat veel mensen hetzelfde denken. Maar goed, vast bang voor de camera en geen mediatraining :Z

Als je in discussie gaat met een trol, wint hij. Als je een trol beledigt, wint hij. Als je tekeer gaat tegen een trol, wint hij. Het enige waar trollen niet tegen kunnen, is te worden genegeerd.
