023-Mars_Water-2.jpgWhere is the "Water" of Mars? (Equatorial and Middle Latitude Regions)57 visiteA Neutron Spectrometer on the Mars Odyssey Spacecraft measures the abundances of neutrons of various energies emitted from Mars' Surface.
The ratio of low- to high-energy neutrons is a sensitive test of water abundances within a meter of Mars' surface.
There is LOTS of water. No one had expected any where near this much water near the Martian Surface.
All this is BETTER described in a press release from the Los Alamos National Laboratory, home of the Neutron Spectrometer and the scientists who run it (http://www.lanl.gov/news/releases/archive/03-101.shtml). MareKromium

Enceladus-5-CASSINI-big.jpgOver and Above... (natural colors; credits: Lunexit)57 visiteCaption NASA:"What does the surface of Saturn's ice-spewing moon Enceladus look like? To help find out, the robotic Cassini Spacecraft now orbiting Saturn was sent soaring past the cryovolcanic moon and even right through one of Enceladus' ice plumes.
Cassini closed to about 52 Km during its closest encounter to date. The above unprocessed image was taken looking down from the North, from about 30.000 Km away. Visible are at least two types of terrain.
The first type of terrain has more craters than occur near Enceladus' South Pole.
The other type of terrain has few craters but many ridges and grooves that may have been created by surface-shifting tectonic activity.
Exogeologists are currently poring over this and other Cassini images from last Wednesday's flyby to better understand the moon's patch-work surface, its unusual ice-geysers, and its potential to support life. Cassini is scheduled to fly by Enceladus at least 9 more times, including an even closer pass of just 25 Km in October 2008".MareKromium

SOL524-2P172890954EFFAC00P2438L7M1-1.jpgExtremely unusual "Boulder" - Sol 524 (context frame; credits: Dr Gianluigi Barca57 visiteIl particolare evinto dal Dr Gianlui Barca in questo frame Spirit è di quelli che lasciano, se non altro - e come minimo -, piuttosto sorpresi: che la Natura si sbizzarrisca, infatti, attraverso la creazione di rilievi le cui forme, tavolta, sono incredibili ed inarrivabili anche per l'Immaginazione del più surreale e fantasioso degli Artisti è un fatto. Ma qui, su Marte (e lo diciamo scherzosamente come ovvio...), sembra proprio che si stia esagerando: andate a guardare l'extra-detail mgnf che segue...
Nota: per quanto attiene qualche nostra nota preliminare sul bizzarro macigno in oggetto (e scritta nel Giugno 2005), Vi rinviamo ai nostri primi (e sommari) commenti che potrete leggere nel quadro intitolato 'A "lonely, big and unusually-shaped" Boulder - Sol 524'.MareKromium

Enceladus-Cassini_big.jpgIs there "Life" underneath Enceladus?!?57 visiteCaption NASA:"Could life exist beneath Enceladus?
A recent flyby of Saturn's icy moon has bolstered this fascinating idea. Two years ago, images from the Cassini Spacecraft led astronomers to the undeniable conclusion that Saturn's moon Enceladus was spewing fountains of gas and ice crystals through cracks in its surface (the "Tiger Stripes").
Last month (February 2008), Cassini dove through some of these plumes and determined that they contained Water Vapor laced with small amounts of Methane as well as simple and complex organic molecules. Surprisingly, the plumes of Enceladus appear similar in make-up to many comets.
What's more, the temperature and density of the plumes indicate they might have originated from a warmer source - possibly a liquid source - beneath the surface.
A liquid water sea containing organic molecules is a good place to look for life.
Pictured above is a vertically exaggerated close-up of some long, venting Tiger Stripes. The computer composite was generated from images and shadows taken during the recent Cassini flyby.
Nine more flybys of Enceladus by Cassini are planned".MareKromium

Janus-PIA09871.jpgJanus and Saturn (natural colors; credits: Lunexit)57 visiteCaption NASA:"The Cassini Spacecraft provides a window on the awesome scale of the Saturn System, with the Giant Planet dominating one of its smaller satellites.
Orbiting here, just outside the Main Ring System, is Janus.
This view looks toward the unilluminated side of the Rings from about 16° above the Ring-Plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 13, 2008. The view was obtained at a distance of approx. 1,6 MKM (about 1 MMs) from Janus and approx. 1,8 MKM (about 1,1 MMs) from Saturn.
Image scale is roughly 10 Km (about 6 miles) per pixel on Janus".MareKromium
