PASADENA – NASA-funded lunar research has yielded evidence of water locked in mineral grains on the surface of the moon from an unknown source deep beneath the surface. Using data from NASA’s Moon Mineralogy Mapper (M3) instrument aboard the Indian Space Research Organization’s Chandrayaan-1 spacecraft, scientists remotely detected magmatic water, or water that originates from deep within the moon’s interior, on the surface of the moon.

The findings, published Aug. 25 in Nature Geoscience, represent the first detection of this form of water from lunar orbit. Earlier studies had shown the existence of magmatic water in lunar samples returned during NASA’s Apollo program.

M3 imaged the lunar impact crater Bullialdus, which lies near the lunar equator. Scientists were interested in studying this area because they could better quantify the amount of water inside the rocks due to the crater’s location and the type of rocks it held. The central peak of the crater is made up of a type of rock that forms deep within the lunar crust and mantle when magma is trapped underground.

Pebbly Rocks Testify to Old Streambed On Mars


May 30, 2013 — Detailed analysis and review have borne out researchers’ initial interpretation of pebble-containing slabs that NASA’s Mars rover Curiosity investigated last year: They are part of an ancient streambed.

 

NASA’s Curiosity rover found evidence for an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here, which the science team has named “Hottah” after Hottah Lake in Canada’s Northwest Territories. It may look like a broken sidewalk, but this geological feature on Mars is actually exposed bedrock made up of smaller fragments cemented together, or what geologists call a sedimentary conglomerate. Scientists theorize that the bedrock was disrupted in the past, giving it the titled angle, most likely via impacts from meteorites. (Credit: NASA/JPL-Caltech/MSSS)

The rocks are the first ever found on Mars that contain streambed gravels. The sizes and shapes of the gravels embedded in these conglomerate rocks — from the size of sand particles to the size of golf balls — enabled researchers to calculate the depth and speed of the water that once flowed at this location.

“We completed more rigorous quantification of the outcrops to characterize the size distribution and roundness of the pebbles and sand that make up these conglomerates,” said Rebecca Williams of the Planetary Science Institute, Tucson, Ariz., lead author of a report about them in the journal Science this week. “We ended up with a calculation in the same range as our initial estimate last fall. At a minimum, the stream was flowing at a speed equivalent to a walking pace — a meter, or three feet, per second — and it was ankle-deep to hip-deep.”

Mars Orbiter Reveals Evidence Of Underground Lakes – And Possibly Life

January 22, 2013 Leave a comment

A new photograph of Mars suggests that huge lakes of liquid water might lie underneath the Red Planet’s surface.

The find has raised hopes that life may have once existed on the planet – and might even still be there.

Nasa said that the image “adds to an increasingly complex picture” of our nearest neighbouring planet.

Researchers analysed data from the Mars Reconnaissance Orbiter spacecraft as it looked down on the floor of the McLaughlin Crater, which is 57 miles in diameter and over 1.4 miles deep.

The picture showed that the crater was once deep enough to let underground water flow into its interior.

Large water reservoirs at the dawn of stellar birth

Large water reservoirs at the dawn of stellar birth

It is surrounded by many other clouds of gas and dust of varying density. The Taurus Molecular Cloud is about 450 light-years from Earth and is the nearest large region of star formation.

ESA’s Herschel space observatory has discovered enough water vapour to fill Earth’s oceans more than 2000 times over, in a gas and dust cloud that is on the verge of collapsing into a new Sun-like star.

Stars form within cold, dark clouds of gas and dust – ‘pre-stellar cores’ – that contain all the ingredients to make solar systems like our own.

Water, essential to life on Earth, has previously been detected outside of our Solar System as gas and ice coated onto tiny dust grains near sites of active star formation, and in proto-planetary discs capable of forming alien planetary systems.

The new Herschel observations of a cold pre- in the constellation of Taurus known as Lynds 1544 are the first detection of water vapour in a molecular cloud on the verge of star formation.

More than 2000 Earth oceans-worth of water vapour were detected, liberated from icy dust grains by high-energy cosmic rays passing through the cloud.

Mars rover Curiosity finds evidence of ancient fast-moving streams on surface of red planet

September 28, 2012 Leave a comment

The Nasa rover Curiosity has beamed pictures back from the red planet that appear to show the remnants of an ancient stream which once ‘ran vigorously’ on the surface of Mars.

The discovery of bedrock and pebbles, which appear to indicate there was once fast moving water on the planet, was described by the mission’s chief scientist as ‘exciting’.

Pebbles, that appear to have been rounded off by water, have offered the most convincing evidence yet that there was water on the surface of Mars.

The visual evidence is presented here in two sampling blocks representing the better of the discoveries. In the first block you’ll see quite a few different bodies of water in a liquid state with some of these surrounded by the bonus of very conventional looking forests. The second block is all about samples of large form forest life Mars style none of which are by official consensus suppose to exist at all on this world.

Remember that the Mars surface is officially suppose to be completely dry and devoid of life. Further, the atmosphere is suppose to be 95.35% carbon dioxide (CO2) with only a very tiny .03% of water vapor and super hard frozen to the tune of as much as –220º Fahrenheit or –140º Celsius. In other words it would be a race as to whether an unprotected Earth human out in the open there would be speedily killed by too much poisonous CO2 gas by many times over or quickly frozen to death.

Note that, even though all of the following evidence is in the official science data and available there for verification, you have never heard a peep out of NASA or JPL as to its existence. So this amounts to the hidden Mars that it appears someone in control does not wish you and I to know about or at least also ignore. Also note that I have added a slight bit of false color to these online images to increase clarity and the viewing comfort level. In any case, the high drama visual evidence is as follows.

Researchers Estimate Ice Content of Crater at Moon’s South Pole


ScienceDaily (June 20, 2012) — NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft has returned data that indicate ice may make up as much as 22 percent of the surface material in a crater located on the moon’s south pole.

The team of NASA and university scientists using laser light from LRO’s laser altimeter examined the floor of Shackleton crater. They found the crater’s floor is brighter than those of other nearby craters, which is consistent with the presence of small amounts of ice. This information will help researchers understand crater formation and study other uncharted areas of the moon. The findings are published in Thursday’s edition of the journal Nature.

“The brightness measurements have been puzzling us since two summers ago,” said Gregory Neumann of NASA’s Goddard Space Flight Center in Greenbelt, Md., a co-author on the paper. “While the distribution of brightness was not exactly what we had expected, practically every measurement related to ice and other volatile compounds on the moon is surprising, given the cosmically cold temperatures inside its polar craters.”
