033-Mars_Rotation.jpgMars' Rotation and Orbit Dynamics129 visiteMars rotation around its pole causes a signature in the data with a daily minimum, when the Lander is closest to the Earth. Changes in such a daily signature may reveal information about the interior of Mars, through its effect on Mars' precession and nutation.
The signature is also sensitive to variations in Mars' Rotation Rate, as the mass of the atmosphere increases and decreases along with the Polar Caps increase and decrease (obviously the Polar Caps increase during the Martian Fall and Winter and then, due to the higher heating of the Planet - and subsequent evaporation phoenomena - they decrease in Spring and Summer).
Long term signatures in the range to the Lander are caused by asteroids perturbing Mars' orbit; an analysis of these perturbations may allow us to also determinate the masses of these asteroids.

APOLLO 11 AS 11-39-5741.jpgAS 11-39-5741 - A flare?176 visiteUna possibile Anomalia: lungo il filo dell'orizzonte, leggermente a Sn dell'ombra del LM, sembra "accendersi"una luce. Istintivamente, analizzando la foto, abbiamo pensato ad un "outgassing" (una delle possibili cause dei cosiddetti TLP o Transient Lunar Phoenomena) o alla presenza di un oggetto metallico in lontananza. In realtà si tratta di un difetto della pellicola, causato da over-processing dell'immagine. Nel frame originale e non compresso, la "flare" non esiste.

C-La Condamine Crater 00.jpgRays of light through "La Condamine Crater" (1)124 visiteNel novero dei cosiddetti TLP (ovvero Transient Lunar Phoenomena) ci sono anche - secondo alcune Scuole di Pensiero - i cosiddetti "Raggi di Luce" i quali, in situazioni di Sole radente (ovviamente con riferimento ai luoghi Lunari coinvolti ed a prescindersi dalla posizione dell'Osservatore Terrestre), si "intrufolano" - se ci passate questa espressione - attraverso i cracks delle murate (rims) di alcuni crateri e, nel farlo, disegnano inusuali - e temporanee, appunto - strisce di luce sul fondo dei crateri stessi.
Quello che Vi proponiamo in questa sequenza è (sembra essere) proprio uno di questi casi.
Per onestà intellettuale, però, pur proponendoVi questa sequenza e pur rispettando profondamente il lavoro dell'Astronomo Robert Spellman, noi riteniamo che questo tipo di fenomenologia, sebbene curiosamente interessante e suggestiva nelle visioni telescopiche della Luna, NON HA nulla a che spartire con la Famiglia Classica dei TLP.

Chaotic_Terrain-Aram_Chaos-R2200155-04.jpgThe "Many Faces" of Aram Chaos (5 - EDM n. 4 - Original NASA/MGS/MSSS b/w Frame)64 visiteUn punto focale - e che ci vede in perfetta sintonìa con il Dr Skipper - attiene l'orrenda manipolazione distorsiva (o "tampering") che viene fatta sulle immagini MGS (o meglio: su tutte le immagini in arrivo dallo Spazio).
Una manipolazione sulle cui reali origini e motivazioni non vale davvero la pena parlarne ora e qui.
"The accumulative evidence that I've seen indicates that the suspicious rounded and oval mounts possibly represents at least indirectly different life equally dependent on this surface water resource but which adopted a different survival strategy. They do not locate on slopes or grades but in more level terrain shallow water pools or where the ground is extra water saturated for a sustained period and then form these large elevated forms. Their plentiful numbers here in Aram Chaos but smaller size relative to some that I've seen may suggest that the shrinking water conditions in Aram Chaos is a relatively more recent phenomena as opposed to a even more ancient scenario"

Enceladus-PIA10573.jpgCrescent Enceladus (Natural Colors; credits: Lunar Explorer Italia)53 visiteCaption NASA:"Sunrise uncovers both old and new Enceladus in this image from the Cassini Spacecraft. The lit side of the moon faces Saturn in this view of the Trailing Hemisphere. Old craters still pockmark the Northern Hemisphere while more recent geologic activity has swept them away in the South. North is on the right (Dx) in this image.
Mountain Ranges, a.k.a. "Dorsae", undulate across the moon's surface near the Equator.
From this high northern viewing angle, the South Pole's fascinating "Tiger Stripe Area" lies just out of view. Sulci, a.k.a. "furrows", in that area, are the sources of icy plumes being studied by Cassini scientists.
(See also PIA07800 and PIA09761).
Also near the Tiger Stripes are rift segments that resemble the zigzag patterns seen on Earth of sea-floor spreading from upwelling magma. See PIA11138 for a comparison of the phenomena.
Like outstretched fingers, the Samarkand Sulci reach from the West toward the North Pole, clearing their path of craters and slicing some in half.
This Natural Colors mosaic combines narrow-angle camera images obtained through UltraViolet, Green, and near-InfraRed camera filters. The images were acquired on Dec. 2, 2008 at a distance of approx. 124.000 Km (such as about 77.000 miles) from Enceladus and at a Sun-Enceladus-Spacecraft, or Phase, Angle of 116°.
Image scale is roughly 742 meters (2430 feet) per pixel".MareKromium

Gullies-Hellas_Planitia-MGS~2.jpgGullies in Hellas Planitia (Absolute Natural Colors; credits for the additional process. and color.: Dr G. Barca - Lunexit Team)53 visiteCaption NASA originale:"This MGS-MOC image shows neighboring networks of gullies in the NorthWestern wall of a South, middle-latitude, crater West of Hellas Planitia. The faint crisscrossing streaks, also observed on the wall of the crater, are evidence of passing Dust Devils, a common phenomena in this Region.
The gullies might have formed by erosion caused by running water, mixed with debris".

Io-PIA00491.jpgIo: five views of the one and the same53 visiteFive color views of Jupiter's moon Io, as seen by NASA's Galileo spacecraft camera, were taken between the 25th and the 29th of June, 1996 Universal Time. The color is a composite of the red, green, and violet filters of the on board imaging system with the brightness of the violet bandpass increased to provide better color discrimination. The full disk images were intended for color mapping of Io's surface and for comparison to Voyager images. Where images overlap several features can be seen to change in relative brightness, perhaps due to unusual light scattering behavior or active phenomena. The crescent images were intended primarily for color imaging of active volcanic plumes on the bright limb and these images showed that the Voyager-era Loki plumes were no longer active and revealed a new plume at Ra Patera. The smallest features which can be discerned in the 5 views range from 9 to 23 kilometers and provide our best look at Io since the 1979 Voyager flybys. Sub-spacecraft longitudes on Io (from upper left to lower right) are 69, 338, 264, 211, and 221 W. North is to the top.
Launched in October 1989, Galileo entered orbit around Jupiter on December 7, 1995. The spacecraft's mission is to conduct detailed studies of the giant planet, its largest moons and the Jovian magnetic environment.

Japetus-PIA06171_modest.jpgLandslide on Japetus52 visiteCaption NASA originale:"A spectacular landslide within the low-brightness region of Japetus's surface known as Cassini Regio. The landslide material appears to have collapsed from a scarp 15 Km high that forms the rim of an ancient 600 Km impact basin. Unconsolidated rubble from the landslide extends halfway across a conspicuous, 120-Km diameter flat-floored impact crater that lies just inside the basin scarp. Landslides are common geological phenomena on many planetary bodies, including Earth and Mars. The appearance of this landslide on an icy satellite with low-brightness cratered terrain is reminiscent of landslide features that were observed during NASA's Galileo mission on the Jovian satellite Callisto. The fact that the Japetus landslide traveled many kilometers from the basin scarp could indicate that the surface material is very fine-grained and perhaps was fluffed by mechanical forces that allowed the landslide debris to flow extended distances".

Jupiter-02.jpgInternal Heat Drives Jupiter's Giant Storm Eruption (IR + VL)52 visiteDetailed analysis of two continent-sized storms that erupted in Jupiter's Atmosphere in March 2007 shows that Jupiter's internal heat plays a significant role in generating atmospheric disturbances. Understanding this outbreak could be the key to unlock the mysteries buried in the deep Jovian Atmosphere, say astronomers.
Understanding these phenomena is important for Earth's meteorology where storms are present everywhere and jet streams dominate the atmospheric circulation. Jupiter is a natural laboratory where atmospheric scientists study the nature and interplay of the intense jets and severe atmospheric phenomena.
An international team coordinated by Agustin Sánchez-Lavega from the Universidad del País Vasco in Spain presents its findings about this event in the January 24 issue of the journal Nature.
The team monitored the new eruption of cloud activity and its evolution with an unprecedented resolution using NASA's HST, the NASA Infrared Telescope Facility in Hawaii, and telescopes in the Canary Islands (Spain).
A network of smaller telescopes around the world also supported these observations.
According to the analysis, the bright plumes were storm systems triggered in Jupiter's deep water clouds that moved upward in the atmosphere vigorously and injected a fresh mixture of ammonia ice and water about 20 miles (30 Km) above the visible clouds. The storms moved in the peak of a jet stream in Jupiter's Atmosphere at 375 mph (600 Km/hour). Models of the disturbance indicate that the jet stream extends deep in the buried atmosphere of Jupiter, more than 60 miles (approx. 100 Km) below the cloud tops where most sunlight is absorbed.MareKromium

Jupiter-Red_Spot-BJ.jpgJupiter's Great Red Spot from Voyager 1 (Credit: NASA, JPL; Digital processing: Dr Björn Jónsson - IAAA)105 visiteCaption NASA:"It is a hurricane twice the size of the Earth. It has been raging at least as long as telescopes could see it, and shows no signs of slowing. It is Jupiter's Great Red Spot, the largest swirling storm system in the Solar System.
Like most astronomical phenomena, the Great Red Spot was neither predicted nor immediately understood after its discovery. Still today, details of how and why the Great Red Spot changes its shape, size, and color remain mysterious. A better understanding of the weather on Jupiter may help contribute to the better understanding of weather here on Earth.
The above image is a recently completed digital enhancement of an image of Jupiter taken in 1979 by the Voyager 1 Spacecraft as it zoomed by the Solar System's largest planet.
At about 117 AU from Earth, Voyager 1 is currently the most distant human made object in the Universe and expected to leave the entire Solar Heliosheath any time now".MareKromium
