Pioneer, Rosetta, Galileo, NIR and Cassini experienced unplanned extra acceleration as they passed by planets. Now a scientist claims to have discovered the reason for this
On December 8, 90, something strange happened to the Galileo spacecraft when it crossed the Earth on its way to Jupiter. While the team was checking the spacecraft's speed data, suddenly there was a jump of 4 mm per second in its speed. No one gave much thought to this - another mm or less does not add or subtract in planetary terms.
On January 23, 98, the same phenomenon occurred in NASA's Nir spacecraft when it hovered above the Earth. This time the jump was 13 mm per hour. A year after that, Cassini's speed jumped by 0.11 mm/s. The speed of the Rosetta spacecraft also jumped by 2 mm/s in 2005 when approaching the Earth, so the scientists started asking questions.
No one knows what caused these jumps, but a new study by Magic McCulloch, an astrophysicist from England, claims that Unro radiation is to blame. The Unro effect theory holds that accelerating bodies experience a type of electromagnetic radiation. At very low acceleration, the wavelength is greater than the dimensions of the universe (a phenomenon known as the Hubble distance).
A small acceleration will produce waves that will not affect the bone. However, the accelerated body (for example Galileo which was accelerated by the Earth's gravity during its approach flight in 1990, and which was smaller than the Hubble distance) undergoes a certain threshold acceleration, the Unro radiation will decrease the wavelength by an amount smaller than the Hubble distance, and cause a small, but measurable increase of the speed. Unro radiation was discovered in 1976 by Bill Unro from the University of British Columbia - according to which an observer who is in acceleration will observe blackbody radiation while an observer who is not moving from his position will not observe a particle.
McCulloch says his idea can be tested in low-acceleration experiments by creating an invisibility cloak to make the object invisible to unro radiation, so it won't experience the acceleration normally.

One more thing for Judah:
The following sentence also appears in the description on Wikipedia:
The effect is so small that it could be a statistical anomaly caused by differences in the way data was collected over the lifetime of the probes.
From this sentence it is possible to conclude (which was quite expected) that the conclusion about the tauta was obtained from speed measurements made from time to time and not from a point measurement of tauta.
The meaning of this fact is that the description of a "permanent yaw" that continues all the time is only one of the conclusions that can be drawn from the measurements that also agree with a series of yaw events.
I am not saying that the second option is better.
I'm just saying that this may be the conclusion reached by the authors of the article.
To Judah:
Actually saying precise things may help.
You should try it more.
The description you just gave really seems different from the effect described.
I don't know if this means that the authors of the article were wrong or that they know something that is not written in Wikipedia.
Of course, this does not correct what you said before, but it at least fits with your claim (the one that talks about the Pioneer effect - not the one that discredits the defamation)
In Pioneer's anomaly, it is a constant motion. Below is a quote:
When all known forces acting on the spacecraft are taken into consideration, a very small but unexplained force remains. It causes a constant sunward acceleration of (8.74 ± 1.33) × 10^-10 m/s2 for both spacecraft.

The previous comment was mine - sorry for the omission
Yehuda:
I do not claim that the phenomena are the same because I do not know the explanation for any of them, although if I read the research after the article I might know.
In any case, the quotes you provided do not prove your point.
In what you quoted from wikipedia about Pioneer, it does not say about permanent damage. Know that even a one-time change in speed (acceleration or deceleration) will create a continuous change in trajectory. Not least, changes that repeat and occur from time to time when you approach this or that planet.
In other words - according to the quotes you brought this could definitely be the same phenomenon.
By the way, even if the quotes proved the claim of the difference between the phenomena, it would not change the fact that your previous response was based on taking things out of context or, in other words, trying to convince in unfair ways.
This attempt will not be erased by any further citation - the only course you can take in relation to it (if you want to protect people's opinion of your integrity) is by way of apology.
sounds interesting.
From Wikipedia in English:
The Pioneer anomaly or Pioneer effect is the observed deviation from expectations of the trajectories of various unmanned spacecraft visiting the outer solar system, notably Pioneer 10 and Pioneer 11.
For those interested in further explanation
http://en.wikipedia.org/wiki/Pioneer_anomaly#_note-1
However
The flyby anomaly is an unexpected energy increase during Earth flybys of satellites. This has been observed as an anomalous shift in the S-Band and X-Band Doppler data which translates to a significant velocity increase of a few mm/s at perigee. So far, no conventional mechanism could be found as being responsible for this effect.
For those interested in further explanation
http://en.wikipedia.org/wiki/Flyby_anomaly
In other words, we are talking about two different phenomena, one - the Pioneer anomaly that affects spacecraft in their distant movement in the extreme solar system, the order of magnitude of about a hundred astronomical units from the sun, and it is about an unexplained continuous flight, and the other that is discussed in this article, The flyby anomaly, that happens in the vicinity of the Earth And also other planets, and you talk about inexplicable acceleration.
These are two different phenomena that are also treated as different in Wikipedia.
The title of the article on the science website based on the original article in Universe Today may be misleading.
Now that I have explained myself, I hope I have proven my scientific and intellectual integrity.
On second thought, I really don't care, for my part, that all the "good souls" think what they want.
Have a pleasant Shabbat rest for all the Nemes, and may the Kinneret climb already in cm.

"At very low acceleration, the wavelength is greater than the dimensions of the universe (a phenomenon known as the Hubble distance)."
Which wave is it about? Do you mean Gal de Bruy? And do I know the dimensions of the universe? There is still no definitive answer about its shape, so how is it possible that we know its dimensions?
Yehuda:
Those who read beyond the headlines see that Universe Today also wrote content and that this content contains the sentence Also known as the Pioneer effect. Why did you take the title out of context? Do you think this is an honest act?
Deceleration and acceleration are basically the same thing and the difference between them depends on the system from which the body is viewed.
I don't claim that I trust the article - to do this you really have to work and go into the details but a decent person does the same thing also to disqualify.
The Pioneer Anomaly according to Wikipedia:
The Pioneer Anomaly, or Pioneer Effect, is an unexpected deviation of several probes visiting the outer solar system, mainly Pioneer 10 and 11, from the trajectory predicted by the theory of relativity. End quote.
Here we are talking about a different kind of anomaly affecting spaceships in transit near the planets.
Here it is an inexplicable push while in the Pioneer anomaly it is an inexplicable urge.
The title of the article in Universe Today also talks about
A Possible Answer to Flyby Anomalies
And not about the Pioneer anomaly, although even there the anomaly is mentioned as an unexplained movement.
So the Pioneer anomaly still remains unexplained
