Re: ISS electric fields
It appears NASA is on to something as a result of their 'tether' experiment back in 1996.
Up, Up, and Away (bit by bit) "The nation that controls magnetism controls the universe."
The Tethered Satellite System employed a large deployment mechanism, resembling a deck winch, in the Space Shuttle payload bay. The winch unreeled 20 km of insulated, conducting tether with a spherical satellite at the end. As the Shuttle orbited the Earth, the electrical wire cut through the Earth's magnetic field , and the motion produced an electrical current. Electrons - which make up a current - were collected by the satellite, through the tether, and flowed out the Shuttle by way of an electron gun that dumped the charge as it built up.
What Stone and other scientists found was that the tethered system produced more current that expected.
"The theoretical models were not accurate on tether," Stone said, "and the currents were higher than we expected." Specifically, the models require that the voltage be 10 times greater to collect a current than what was observed. Before the flight, the models predicted that the tether would produce 0.5 amp (0.5 A) under ideal conditions. Instead, it produced more than 1 amp under less than ideal conditions.
The Tethered Satellite System (TSS) carried on the Space Shuttle was a large, complex system. Discoveries from are showing how smaller tethers can be used to keep satellites in orbit.
"The models were a factor of two or three off because they don't include the effects of orbital motion through the plasma (electrified gas) of the ionosphere," Stone said. While motion of a conductor through the magnetic field is crucial (it's also how a generator in a power plant works), motion through the electrons in space was thought to be a miniscule effect. The Shuttle moves at 7.7 km/s (17,500 mph) while the electrons move at 200 km/s (115,000 mph).
It turns out that the current carried by those electrons connected nicely with the tethered system and "contributed significantly" to the power generated.
Dr. J. R. Sanmartin of the Polytechnic University of Madrid, Spain, predicted that a tethered system did not need a large sphere at the end of the line to work. The motion of a satellite through space generate a plasma shield that stands off about 1 cm (0.4 in) away from the spacecraft surface. On the 1.8 m (6 ft) diameter TSS, that 1 cm standoff adds only about 2 percent to the collecting area. On a wire, it increases the collecting area 400-fold or more, so that an 82-meter wire now has as much effective collecting area as the 1.8-meter sphere.
"If this new bare wire tether works as advertised," Stone said. "it would allow us to collect considerably more current for a given length of tether." As a result, shorter tethers could be used for propulsion or to generate electrical power.

Excellent find Ben D. I thought I was reading a TPOD!!! - in their own words to boot!

Re: ISS electric fields
Thanks Solar, BTW the link for the 'Propulsive Small Expendable Deployer System - ProSEDS' that was to be a follow on experiment, in that article didn't work for me,.. here is one that I found from a quick google. Very interesting to see NASA's plans to wire it up in the electrical motor mode for raising the orbit of spacecraft.
Plugged in to space - Proposed flight demonstration will show how to keep space clean - and boost satellites
In the ProSEDS demonstration, it's a 15 km(9.3 mi) tether unwound upward from the Delta II rocket stage. The upper 10 km (6.2 mi) are nonconducting, and the lower 5 km (3.1 mi) are a bare wire to make an electrical connection with the ionized gases - plasmas - of space.
The slight decrease in Earth's gravity across the length of the tether actually pulls the two ends apart, keeping the tether stretched out. Once unreeled, the tether moves across the Earth's magnetic field lines and, in "generator mode," produces an electrical current through the tether. A hollow cathode then ejects electrons back into space, thus completing the circuit - and putting the brakes on the rocket.
"The next step would be another demonstration that shows orbit raising by using the tether in the 'motor mode.' Rather than generating power, the tether system could use electrical power from solar arrays to generate thrust and boost the satellite's altitude," Johnson continued. That probably would require a dedicated spacecraft for the demonstration. But it would be a worthwhile investment that could lead to a savings of up to $2 billion in space station operations costs, power space tugs taking satellites to higher orbits, and possibly reduce the weight and cost of probes to Jupiter and its moons.

The tether video was the most unusal thing I have ever seen.

Re: ISS electric fields
The events tell a tale of stark contrast in the world of astrophysics and cosmology. Often one can encounter characterizations of EU/Plasma Cosmology ideas and it's proponents as being generally 'rebellious' and the theory in need of mathematical erudition.
They're creating electricity for the ISS via running a wire through the Earth's magnetic field but some astronomers and cosmologist don't make the necessary, and practical, quantum leap in ascertaining the origin of those magnetic fields?
I reference individuals such as Phil Plait - Bad Astronomer vs. Good Science who apparently works for NASA or some associated entity thereof or ScienceApologist and the educational system. Yet; while the polemic diatribe continues the company Plait works for is figuring out ways to literally get "Plugged in to space".
It's truly amazing and defies all reasonable attempts to understand.

The Pioneer Anomaly revisited
Just came across this thread and as I was dealing with the well known "anomaly"-problem lately I want to provide you with an abstract about the Study of the anomalous acceleration of Pioneer 10 and 11
Besides a lot of useful data you should focus your attention towards page 29 where amongst other "possible causes" for the deviation it is stated:
It seems that any effective electrical field by the Sun was NOT taken into consideration - moreover it looks that they interpolated the near-Sun measurements.
It seems that the alternating topography of the Solar "Ballerina-Skirt" field - with its ups-and-downs - was NOT taken into consideration.
It seems that any Plasma-related effect (double layer) was NOT taken into consideration.
...
Perhaps any one from here wants to do some EM-related math?
Just my 1.616 Cents.

Besides a lot of useful data you should focus your attention towards page 29 where amongst other "possible causes" for the deviation it is stated:
This is the only reference towards possible EM-sources for the acceleration-anomaly, besides other more or less mechanical investigations.D. Electro-magnetic Lorentz forces
The possibility that the spacecraft could hold a charge,
and be deflected in its trajectory by Lorentz forces, was
a concern for the magnetic field strengths at Jupiter and
Saturn. However, the magnetic field strength in the outer
solar system is on the order of < 1 γ (γ = 10^−5 Gauss).
This is about a factor of 10^5 times smaller than the magnetic
field strengths measured by the Pioneers at their
nearest approaches to Jupiter: 0.185 Gauss for Pioneer
10 and 1.135 Gauss for the closer in Pioneer 11 [93].
Also, there is an upper limit to the charge that a spacecraft
can hold. For the Pioneers that limit produced an
upper bound on the Lorentz acceleration at closest approach
to Jupiter of 20 × 10^−8 cm/s2 [87]. With the
interplanetary field being so much lower than at Jupiter,
we conclude that the electro-magnetic force on the Pioneer
spacecraft in the outer solar system is at worst on
the order of 10^−12 cm/s2, completely negligible [94].
Similarly, the magnetic torques acting on the spacecraft
were about a factor of 10^−5 times smaller than
those acting on Earth satellites, where they are a concern.
Therefore, for the Pioneers any observed changes
in spacecraft spin cannot be caused by magnetic torques....

Rosetta spacecraft to observe gravity boost anamoly
A release yesterday from the European Space Agency (ESA) notes that their comet-chasing probe, Rosetta, will swing by the Earth to get a gravity boost en route to its targeted comet. A number of spacecraft NEAR; Galileo) utilizing this maneuver have exhibited unexplainable anomalous velocity changes, apparently, and scientists cannot yet explain why. Such changes range from no change to as much as 13 mm/s. They have ruled out "atmospheric drag" as a reason (duh! drag decelerates as it extracts orbital energy) but apparently cannot substitute anything else to account for the departures from their predicted acceleration during the probe-Earth interaction. These fall into the larger category of unexplainable velocity anomalies, including the Pioneer perturbations which were completely unexpected, as well.
[color=#0040FF]http://www.esa.int/SPECI ... ml[/color]
Perhaps EU scientists could link gravity with E/M phenomena to explain these things. Perhaps Miles Mathis's ideas on the unified field would account for these tiny differentials based on the spacecraft's and Earth's gravity/charge balances at various distances apart. There seems to be some reference to altitude above Earth during these slingshot maneuvers, but the altitudes are not given for all such passes. Do these probes gather or discharge electric charge during their voyages elsewhere before returning to the Earth environment for their gravity boost, and could this factor in? Do scientists consider every conceivable angle in their search for an answer? -and don't forget the always mysterious influence of Dark Things, too.

Of course they don't! Between compartmentalization and 'accepted dogma' it's rare to hear of a discovery even making it to the light of day. Just look at the discoveries of Birkeland, Alfven, Jeurgens, and others brought the Electric Universe into being by breaking through the intedisciplinary walls and looking at the quandaries of one science with the eyes of another.Do scientists consider every conceivable angle in their search for an answer?

Re: Rosetta spacecraft to observe gravity boost anamoly
I think there's another element that needs to be factored into this too: Training. That Doctorate in Whatever demands a LOT of rigorous intellectual training/IN-doctrin-ation - the basis of which, begins in the cradle for almost everyone. Subject a person to enough focused and guided training, be it science, politics or religion, and they will begin to exhibit signs of a hypnotic state. There are concepts that they are simply unaware of because they lie outside of their intellectual entrainment, their hypnosis, their world-view. And, more often than not, attempting to bring such alien concepts into view is tantamount to trying to convince a hypnotized person who thinks he's eating a big, juicy, red apple, that he's actually eating an onion. At best, you wouldn't be taken seriously. At worst, you wouldn't even be heard.mharratsc wrote:JJohnson said:Of course they don't!

I'm convinced that the reason so many scientists today aren't finding real answers (answers that are just waiting to be found) is simply because they keep asking the wrong questions. . . over and over and over. . .
It's all about perception.

Re: Rosetta spacecraft to observe gravity boost anamoly
Mike - yeah, I see this all the time and just cringe. Sometimes I write corrections or EU observation, but that goes the way of Halton Arp's career in the U.S., doesn't it? Android means man-like and hence the predisposition to typos!!
SJ - That's why I call them ortho-docs! They are all forced by training into the same mold so that they can advance along the deepening wagon ruts only. Increasingly, even when observing, they are only trying to do something a teensy different (but never too different) to fill in the chinks and prop things up and get accepted for publication. Consistency is ever the hobgoblin of small minds... Which is precisely why I enjoy and fit in with the viewpoints, generally, of the PC/EU folks. Fresh ideas and viewpoints argued in multiple forums by skeptical but open and critically enquiring minds.

How far up is the ISS?
And how far does the plasma field reach into space?

So here we have NASA finally investigating the process that Kristian Birkeland put forth over one hundred years ago... and not a damn bit of it is making it to popular media, at least that I've seen at any rate. :\
