The skies are very earthlike when they are not red from dust. There's no way that 6 millibars of atmospheric pressure will make such a bright blue sky. NASA has NOT been forthright with us concerning the real conditions of Mars, including atmosphere, life and water. The bright blue skies of Mars belie the 6 millibar atm. pressure Big Lie that NASA has been peddling.


Xuxalina: I was wondering if you can back this up with proof, including the science behind the statements..of couse accusing NASA of lying is another gratuitous statement somewhat hard to demonstrate, but maybe you could try..

Why is the sky blue? sounds like a simple question, but when you find various explanations it obviously isn't. Miles Mathis as usual has his own theories which involve his own version of the photon which solve more problems of light and colour than any other that I have come across. http://milesmathis.com/sky.html

It may help to return to his "updates" and follow a few of his papers on various aspects of light before dismissing his blue sky theory out of hand. As a very competent artist and polymath he has no doubt put much thought into colour in all its forms.

Martian weather reports show extreme atmo pressure swings

Unread postby viscount aero » Sat Oct 06, 2012 4:15 pm

Latest from NASA cites "resonance" as phenomenon behind the atmospheric pressure differentials:

Professor says NASA's Martian weather reports show extreme pressure swings:
Honolulu, HI (SPX) Sep 27, 2012

excerpt from:
http://www.marsdaily.com/reports/Profes ... s_999.html

Curiosity, the NASA rover that landed on Mars last month, is sending us remarkable weather observations from the Martian surface that are attracting interest from scientists. "From a weather point of view, Mars is the most 'Earth-like' of the other planets in our solar system, and many features of the weather there are similar to Earth," says Kevin Hamilton, a pioneer in the area of computer modeling of the Martian atmosphere.

Hamilton, who is Director of UH Manoa's International Pacific Research Center and a Professor of Meteorology, noted that Curiosity is the fifth 'Weather Station' on Mars. Over the last 35 years, a total of four NASA probes had reached the Martian surface and returned weather data.

"These earlier observations had shown a large daily cycle in temperature and air pressure on Mars. The atmospheric temperature near the surface of Mars generally varies by more than 37C (100F) between day and night because of the overall thinner Martian atmosphere and lack of oceans and their moderating influence," says Hamilton.

"The exciting new result from Curiosity is a regular and truly enormous swing in atmospheric pressure through each day. Measurements on Earth show a daily swing in pressure of only about one-tenth of 1% of the mean pressure, whereas Curiosity is measuring swings of almost 10% of the daily average pressure.

"We observe such a relative pressure change on Earth only with the passage of an extremely strong hurricane. At the Curiosity site on Mars, this enormous pressure swing occurs regularly every day!"

Martian Auroras
Aug 19, 2009

Mars has no global magnetic field, so the fortuitous discovery of an aurora event near the south pole surprised astronomers.
Terrestrial auroras are thought to be generated when the Earth’s magnetic field deflects solar wind particles to the magnetic poles. The particles are somehow accelerated along magnetic field lines, and when the lines dive toward the surface, the particles collide with atoms in the atmosphere, causing the atoms to emit light.

Indications of thousands of aurora events turned up in a review of space probe data. Reviewers constructed a map of occurrences and found that they clustered around the margins of magnetic patches on the surface. The patches are thought to be crustal rocks that have preserved magnetic fields acquired from an ancient global field that has decayed. Why they occur almost entirely in the southern hemisphere is not understood.

Theorists speculate that the solar magnetic field lines, which are thought to be “frozen” into the solar wind, “break” and reconnect to the crustal field lines, “flinging” electrons to high energies. It’s “a physical process still not understood.”

Astronomers might begin to understand if they did some homework in the pages of the plasma science journals. Magnetic field lines are symbolic representations of what in reality is a continuous measure of magnetic force. The lines are a convention to indicate the direction of the force at each point in space, and their spacing indicates the strength. But the lines, being imaginary constructs, cannot “freeze” or break or reconnect or “fling” anything. Attributing actions to imaginary constructs is a lazy excuse for failing to describe actual mechanisms that, in this case, have already been described by others.

Charged particles streaming in the same direction as the magnetic field constitute “field aligned currents,” or Birkeland currents, named after the Norwegian scientist who, in the late 19th century, first proposed their existence as the cause of auroras. Birkeland currents generate “double layers” along their paths as the current fluctuates. Double layers are regions of electrostatic charge separation maintained by the forces in the current. Strong electric fields build up between the layers, and charged particles that flow into these regions are accelerated to high energies.

It’s no wonder astronomers fail to understand: they have reversed cause (electric currents) and effect (magnetic fields), they have denied the existence or downplayed the importance of the electrical processes, and they have asked the wrong questions. The magnetism in the patches is reinforced by, if not entirely generated by, the current channels that enclose the patches. Because a persistent current must be part of a larger circuit, astronomers should be asking why the currents are especially strong in the southern hemisphere, and where do they go. Where’s the rest of the circuit?

The Electric Universe suggests that the answer likely has something to do with the different planetary configuration indicated by the cosmogonic stories of prehistoric peoples. Common themes and images found in ancient cultures around the globe point to electrical interactions between Earth and Mars, in which Earth’s northern polar region and Mars’s southern polar region were swept by an electrical vortex similar to what may be seen today, at much higher energies, in the penumbras of sunspots.

It’s likely that crustal rocks from Earth could be electrically deposited on Mars and heated. If they cooled below the Curie point before the current and its accompanying magnetic field completely decayed, they would retain the magnetism. Since Mars has no global magnetic field in which the spots would appear merely as local deflections, they stand out as foci for aurora events.

The Martian limb (that is, the observed ‘edge’ of the planet) represents a unique window into the complex atmospheric phenomena occurring there. Clouds of ice crystals (CO2 ice or H2O ice) have been observed numerous times by spacecraft and ground-based telescopes, showing that clouds are typically layered and always confined below an altitude of 100 kilometres; suspended dust has also been detected at altitudes up to 60 kilometres during major dust storms1, 2, 3, 4, 5, 6. Highly concentrated and localized patches of auroral emission controlled by magnetic field anomalies in the crust have been observed at an altitude of 130 kilometres7. Here we report the occurrence in March and April 2012 of two bright, extremely high-altitude plumes at the Martian terminator (the day–night boundary) at 200 to 250 kilometres or more above the surface, and thus well into the ionosphere and the exosphere8, 9. They were spotted at a longitude of about 195° west, a latitude of about −45° (at Terra Cimmeria), extended about 500 to 1,000 kilometres in both the north–south and east–west directions, and lasted for about 10 days. The features exhibited day-to-day variability, and were seen at the morning terminator but not at the evening limb, which indicates rapid evolution in less than 10 hours and a cyclic behaviour. We used photometric measurements to explore two possible scenarios and investigate their nature. For particles reflecting solar radiation, clouds of CO2-ice or H2O-ice particles with an effective radius of 0.1 micrometres are favoured over dust. Alternatively, the plume could arise from auroral emission, of a brightness more than 1,000 times that of the Earth’s aurora, over a region with a strong magnetic anomaly where aurorae have previously been detected7. Importantly, both explanations defy our current understanding of Mars’ upper atmosphere.

The researchers related those bursts of atmospheric loss to solar events known as corotating interaction regions (CIRs). CIRs form when regions of fast solar wind encounter slower solar wind, creating a high-pressure pulse. When these CIR pulses pass by Mars, they can drive away particles from Mars's atmosphere.
The authors found that during times when these CIRs occurred, the outflow of atmospheric particles from Mars was about 2.5 times the outflow when these events were not occurring. Furthermore, about one third of the material lost from Mars into space is lost during the impact and passing of CIRs.
The study should help scientists better understand the evolution of Mars's atmosphere.

Professor Mark Lester, Head of the Department of Physics and Astronomy at the University of Leicester said: "The main reason it happens at Mars and not at Earth is the lack of a magnetic field produced by the planet, which protects the atmosphere at Earth.
"One other aspect of this work is that the observations were made during a very quiet period in the eleven year solar cycle and so we would expect the effect of these and other large scale disturbances to be higher at other times in the solar cycle."

Solar Wind-Induced Atmospheric Erosion at Mars: First Results from ASPERA-3 on Mars Express

The Analyzer of Space Plasma and Energetic Atoms (ASPERA) on board the Mars Express spacecraft found that solar wind plasma and accelerated ionospheric ions may be observed all the way down to the Mars Express pericenter of 270 kilometers above the dayside planetary surface. This is very deep in the ionosphere, implying direct exposure of the martian topside atmosphere to solar wind plasma forcing. The low-altitude penetration of solar wind plasma and the energization of ionospheric plasma may be due to solar wind irregularities or perturbations, to magnetic anomalies at Mars, or both

A Sporadic Third Layer in the Ionosphere of Mars

The daytime martian ionosphere has been observed as a two-layer structure with electron densities that peak at altitudes between about 110 and 130 kilometers. The Mars Express Orbiter Radio Science Experiment on the European Mars Express spacecraft observed, in 10 out of 120 electron density profiles, a third ionospheric layer at altitude ranges of 65 to 110 kilometers, where electron densities, on average, peaked at 0.8 x 1010 per cubic meter. Such a layer has been predicted to be permanent and continuous. Its origin has been attributed to ablation of meteors and charge exchange of magnesium and iron. Our observations imply that this layer is present sporadically and locally.

One of those "anti-science" EU believers would probably say it's an electric dust devil lofting the dust off the surface—thus explaining the "aurora" on the bottom and the dust on the top.

Meanwhile, a mainstream astronomer would probably say a micro black hole collided with Mars creating the UV light show and plume of dust.

It is very interesting though that the aurora is in the northern hemisphere.

MAVEN's Imaging Ultraviolet Spectrograph (IUVS) observed what scientists have named "Christmas lights." For five days just before Dec. 25, MAVEN saw a bright ultraviolet auroral glow spanning Mars' northern hemisphere. Aurora, known on Earth as northern or southern lights, are caused by energetic particles like electrons crashing down into the atmosphere and causing the gas to glow.

Image

"What's especially surprising about the aurora we saw is how deep in the atmosphere it occurs - much deeper than at Earth or elsewhere on Mars,” said Arnaud Stiepen, IUVS team member at the University of Colorado. “The electrons producing it must be really energetic."

The source of the energetic particles appears to be the sun. MAVEN's Solar Energetic Particle instrument detected a huge surge in energetic electrons at the onset of the aurora. Billions of years ago, Mars lost a global protective magnetic field like Earth has, so solar particles can directly strike the atmosphere. The electrons producing the aurora have about 100 times more energy than you get from a spark of house current, so they can penetrate deeply in the atmosphere.


and the dust has some odd things as well:

The presence of the dust at orbital altitudes from about 93 miles (150 kilometers) to 190 miles (300 kilometers) above the surface was not predicted. Although the source and composition of the dust are unknown, there is no hazard to MAVEN and other spacecraft orbiting Mars.

"If the dust originates from the atmosphere, this suggests we are missing some fundamental process in the Martian atmosphere," said Laila Andersson of the University of Colorado's Laboratory for Atmospherics and Space Physics (CU LASP), Boulder, Colorado.

The cloud was detected by the spacecraft’s Langmuir Probe and Waves (LPW) instrument, and has been present the whole time MAVEN has been in operation. It is unknown if the cloud is a temporary phenomenon or something long lasting. The cloud density is greatest at lower altitudes. However, even in the densest areas it is still very thin. So far, no indication of its presence has been seen in observations from any of the other MAVEN instruments.

Possible sources for the observed dust include dust wafted up (?) from the atmosphere; dust coming from Phobos and Deimos, the two moons of Mars; dust moving in the solar wind away from the sun; or debris orbiting the sun from comets. However, no known process on Mars can explain the appearance of dust in the observed locations from any of these sources.
http://www.nasa.gov/press/2015/march/nasa-spacecraft-detects-aurora-and-mysterious-dust-cloud-around-mars/

Of course nasa press releases and containing commentary have to be taken as they are.
But at Nature it is quite the same, imagine the shock.

NASA's MAVEN spacecraft has discovered a dust cloud billowing over Mars, up to [color=#FF0000]1,000 kilometres above the planet's surface[/color]. The dust does not threaten spacecraft orbiting the red planet, but the unexpected finding poses big challenges to atmospheric researchers, who are trying to explain where the cloud came from.

The spacecraft arrived at Mars last September to fly through and study the planet's upper atmosphere. One of its instruments, called the Langmuir Probe and Wave instrument, measures the densities and temperatures of electrons. It has picked up small whiffs of plasma that form when dust hits the spacecraft and vaporizes, says Jakosky. Similar tiny impacts have been measured elsewhere in the Solar System by other spacecraft, such as the Voyager and Cassini probes, but have never previously been found at Mars.

The dust seems to be concentrated between about 150 and 500 kilometres above the Martian surface, and there is more on the day side, the hemisphere lit by the Sun, than on the night side of Mars. It has been seen ever since the spacecraft arrived at Mars, so it is not related to Comet Siding Spring, which whizzed past the planet in October and dumped a load of fresh dust in the Martian atmosphere.

Jasper Halekas, a space physicist at the University of Iowa in Iowa City, says that the MAVEN findings are already rewriting what scientists know about the magnetic realms around Mars. “It's not your grandfather's magnetosphere,” he says.
http://www.nature.com/news/mystery-dust-cloud-and-aurora-spotted-on-mars-1.17152

So we had patchy aurora's near magnetic areas in the southern hemisphere, but now also in the
magnetically deficient northern hemisphere. And at lower altitudes as well, but because the particles are
so energetic?
And what about the dust blob seen by Hubble? And those famous hazy skies of Mars seen on the images
of Mars landers?
Allthough maybe, remembering the stark red images from the first landers and comparing
those with images today, I might have an idea where all that dust in space came from.
Maybe it is camera-shy dust. :roll:
