When we do make a manned mission to Mars, it seems so strange to have a craft just floating all the way to Mars seeing as it takes so long. I assume that we'll have some way of making the trip quicker? (ex: I heard of solar sails using lasers to slowly increase velocity)

Mars rover discovers geological mystery


08:55 AEST Sat Sep 15 2012




NASA's Opportunity rover, older brother to the Curiosity rover that landed on Mars last month, has made a new discovery that geologists find both puzzling and exciting, the US space agency said on Friday.
Opportunity, which has been on the Red Planet since 2004, has come across an outcrop of tiny spheres - up to around an eighth of an inch (three millimetres) in diameter - the likes of which scientists have never seen before.
"This is one of the most extraordinary pictures from the whole mission," said Opportunity's principal investigator, Steve Squyres of Cornell University in Ithaca, New York.
"We never have seen such a dense accumulation of spherules in a rock outcrop on Mars," he added, in a statement.
At first glance, the researchers thought the objects resembled iron-rich spheres, nicknamed "blueberries", discovered near the Opportunity landing site.
The so-called Martian blueberries are formed when minerals separate from water and become hard masses inside sedimentary blocks - they're part of the evidence Mars used to be wet.
Do you think there could be life on Mars? Have your say below.
But closer investigation revealed the new discoveries are "different in concentration. They are different in structure. They are different in composition. They are different in distribution", Squyres said.
"It's going to take a while to work this out, so the thing to do now is keep an open mind and let the rocks do the talking."
Opportunity found the spheres at an outcrop called Kirkwood, in the Cape York segment of Endeavour Crater's western rim.
Although Opportunity's prime mission was completed more than eight years ago, the rover has continued on "bonus" missions since then.
Fellow Mars rover Spirit, also launched in the summer of 2003, continued working until March 2010.
The most recent Mars lander, Curiosity, is on a two-year quest to explore Mars geology. The $US2.5 billion ($A2.38 billion) robot is currently in the Gale crater, trundling towards Mount Sharp.

Either Nuclear Engines (Which I doubt the UN would allow) or if a lot of money was put into developing ion engines.

I'm not even sure there's money in the UK budget or for NASA to help develop this.
But I'd prefer a manned crew option, instead of unmanned and having a passenger module in the cargo bay.

Driving and Moon-Watching

Wed, 19 Sep 2012 02:12:20 AM UTC+1000


On Sol 42 (Sept. 17, 2012), Curiosity drove about 105 feet (32 meters), toward the east-southeast, bringing the mission's total driving distance to about 850 feet (259 meters). The Dynamic Albedo of Neutrons (DAN) instrument was used at two stops during the drive to check for hydrogen in the soil beneath the rover.

During this sol, the rover used its Mast Camera to observe Mars' two moons, Phobos and Deimos, as each passed in front of the sun.

Curiosity continues to work in good health. Sol 42, in Mars local mean solar time at Gale Crater, ends at 11:12 a.m. Sept. 18, PDT.

'Jake Matijevic' Contact Target for Curiosity

The drive by NASA's Mars rover Curiosity during the mission's 43rd Martian day, or sol, (Sept. 19, 2012) ended with this rock about 8 feet (2.5 meters) in front of the rover. The rock is about 10 inches (25 centimeters) tall and 16 inches (40 centimeters) wide. The rover team has assessed it as a suitable target for the first use of Curiosity's contact instruments on a rock. The image was taken by the left Navigation camera (Navcam) at the end of the drive.

On the Road to Glenelg

This mosaic from the Mast Camera on NASA's Curiosity rover shows the view looking toward the "Glenelg" area, where three different terrain types come together. All three types are observed from orbit with the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. By driving there, Curiosity will be able to explore them.
One of the three terrain types is light-toned with well-developed layering, which likely records deposits of sedimentary materials. There are also black bands that run through the area and might constitute additional layers that alternate with the light-toned layers. The black bands are not easily seen from orbit and are on the order of about 3.3-feet (1-meter) thick. Both of these layer types are important science targets.

Curiosity's Rock-Contact Science Begins

This image shows the robotic arm of NASA's Mars rover Curiosity with the first rock touched by an instrument on the arm. The rover's right Navigation Camera (Navcam) took this image during the 46th Martian day, or sol, of the mission (Sept. 22, 2012). On that sol, the rover placed the Alpha Particle X-Ray Spectrometer (APXS) instrument onto the rock to assess what chemical elements were present in the rock. The rock is named "Jake Matijevic" in commemoration of influential Mars-rover engineer Jacob Matijevic (1947-2012).

Mars Rover Makes Huge New Discovery


NASA Rover Finds Old Streambed on Martian Surface

(Click on picture to enlarge)
Posted Image

PASADENA, Calif. -- NASA's Curiosity rover mission has found evidence a stream once ran vigorously across the area on Mars where the rover is driving. There is earlier evidence for the presence of water on Mars, but this evidence -- images of rocks containing ancient streambed gravels -- is the first of its kind.

Scientists are studying the images of stones cemented into a layer of conglomerate rock. The sizes and shapes of stones offer clues to the speed and distance of a long-ago stream's flow.

"From the size of gravels it carried, we can interpret the water was moving about 3 feet per second, with a depth somewhere between ankle and hip deep," said Curiosity science co-investigator William Dietrich of the University of California, Berkeley. "Plenty of papers have been written about channels on Mars with many different hypotheses about the flows in them. This is the first time we're actually seeing water-transported gravel on Mars. This is a transition from speculation about the size of streambed material to direct observation of it."

The finding site lies between the north rim of Gale Crater and the base of Mount Sharp, a mountain inside the crater. Earlier imaging of the region from Mars orbit allows for additional interpretation of the gravel-bearing conglomerate. The imagery shows an alluvial fan of material washed down from the rim, streaked by many apparent channels, sitting uphill of the new finds.

The rounded shape of some stones in the conglomerate indicates long-distance transport from above the rim, where a channel named Peace Vallis feeds into the alluvial fan. The abundance of channels in the fan between the rim and conglomerate suggests flows continued or repeated over a long time, not just once or for a few years.

The discovery comes from examining two outcrops, called "Hottah" and "Link," with the telephoto capability of Curiosity's mast camera during the first 40 days after landing. Those observations followed up on earlier hints from another outcrop, which was exposed by thruster exhaust as Curiosity, the Mars Science Laboratory Project's rover, touched down.

"Hottah looks like someone jack-hammered up a slab of city sidewalk, but it's really a tilted block of an ancient streambed," said Mars Science Laboratory Project Scientist John Grotzinger of the California Institute of Technology in Pasadena.

The gravels in conglomerates at both outcrops range in size from a grain of sand to a golf ball. Some are angular, but many are rounded.

"The shapes tell you they were transported and the sizes tell you they couldn't be transported by wind. They were transported by water flow," said Curiosity science co-investigator Rebecca Williams of the Planetary Science Institute in Tucson, Ariz.

The science team may use Curiosity to learn the elemental composition of the material, which holds the conglomerate together, revealing more characteristics of the wet environment that formed these deposits. The stones in the conglomerate provide a sampling from above the crater rim, so the team may also examine several of them to learn about broader regional geology.

The slope of Mount Sharp in Gale Crater remains the rover's main destination. Clay and sulfate minerals detected there from orbit can be good preservers of carbon-based organic chemicals that are potential ingredients for life.

"A long-flowing stream can be a habitable environment," said Grotzinger. "It is not our top choice as an environment for preservation of organics, though. We're still going to Mount Sharp, but this is insurance that we have already found our first potentially habitable environment."

Link to a Watery Past

Posted Image

In this image from NASA's Curiosity rover, a rock outcrop called Link pops out from a Martian surface that is elsewhere blanketed by reddish-brown dust. The fractured Link outcrop has blocks of exposed, clean surfaces. Rounded gravel fragments, or clasts, up to a couple inches (few centimeters) in size are in a matrix of white material. Many gravel-sized rocks have eroded out of the outcrop onto the surface, particularly in the left portion of the frame. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Water transport is the only process capable of producing the rounded shape of clasts of this size.

The Link outcrop was imaged with the 100-millimeter Mast Camera on Sept. 2, 2012, which was the 27th sol, or Martian day of operations.

The name Link is derived from a significant rock formation in the Northwest Territories of Canada, where there is also a lake with the same name.

Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain.

Rock Outcrops on Mars and Earth

Posted Image

This set of images compares the Link outcrop of rocks on Mars (left) with similar rocks seen on Earth (right). The image of Link, obtained by NASA's Curiosity rover, shows rounded gravel fragments, or clasts, up to a couple inches (few centimeters), within the rock outcrop. Erosion of the outcrop results in gravel clasts that fall onto the ground, creating the gravel pile at left. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. A typical Earth example of sedimentary conglomerate formed of gravel fragments in a stream is shown on the right.

An annotated version of the image highlights a piece of gravel that is about 0.4 inches (1 centimeter) across. It was selected as an example of coarse size and rounded shape. Rounded grains (of any size) occur by abrasion in sediment transport, by wind or water, when the grains bounce against each other. Gravel fragments are too large to be transported by wind. At this size, scientists know the rounding occurred in water transport in a stream.

The name Link is derived from a significant rock formation in the Northwest Territories of Canada, where there is also a lake with the same name.

Scientists enhanced the color in the Mars image to show the scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain.

Curiosity's Roadside Discoveries

Posted Image

This map shows the path on Mars of NASA's Curiosity rover toward Glenelg, an area where three terrains of scientific interest converge. Arrows mark geological features encountered so far that led to the discovery of what appears to be an ancient Martian streambed. The first site, dubbed Goulburn, is an area where the thrusters from the rover's descent stage blasted away a layer of loose material, exposing bedrock underneath. Goulburn gave scientists a hint that water might have transported the pebbly sandstone material making up the outcrop. The second feature, a naturally exposed rock outcrop named Link, stood out to the science team for its embedded, rounded gravel pieces. Such rounded shapes are strong evidence of water transport. The final feature, another naturally exposed rock outcrop named Hottah, offered the most compelling evidence yet of an ancient stream, as it contains abundant rounded pebbles. The grain sizes are also an important part of the evidence for water: the rounded pebbles, which are up to 1.6 inches (4 centimeters) in size, are too large to have been transported by wind.

The image used for the map is from an observation of the landing site by the High Resolution Imaging Science Experiment (HiRISE) instrument on NASA's Mars Reconnaissance Orbiter.

Where Water Flowed Downslope

Posted Image

This image shows the topography, with shading added, around the area where NASA's Curiosity rover landed on Aug. 5 PDT (Aug. 6 EDT). Higher elevations are colored in red, with cooler colors indicating transitions downslope to lower elevations. The black oval indicates the targeted landing area for the rover known as the "landing ellipse," and the cross shows where the rover actually landed.

An alluvial fan, or fan-shaped deposit where debris spreads out downslope, has been highlighted in lighter colors for better viewing. On Earth, alluvial fans often are formed by water flowing downslope. New observations from Curiosity of rounded pebbles embedded with rocky outcrops provide concrete evidence that water did flow in this region on Mars, creating the alluvial fan. Water carrying the pebbly material is thought to have streamed downslope extending the alluvial fan, at least occasionally, to where the rover now sits studying its ancient history.

Elevation data were obtained from stereo processing of images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

That's so cool. I think it's case closed on there being water on Mars in the past at this point. If there's evidence of life on Mars, it's bound to be in a stream region like that.

The exciting thing, is that one would assume that finding life in a river bed or somewhere that water flowed would make it a no-brainer to look for evidence of life....BUT, NASA scientists are even more excited about the layers at the base of Mt. Sharp even with the knowledge of this river bed.....which makes me excited because they seem to have had their confidence boosted even moreso after coming across the direct evidence of flowing water on Mars.

I can't wait for them to actually get there and start analyzing with MAHLI, the close up hi-res colour camera, and its other lab instruments.

I'm waiting for the day they announce that they believe that they've found evidence of current or past life on Mars. What an absolutely mind-blowing day that'll be.

WOW Astronomy is one of the things that just absolutely fascinates me. Water on Mars is a huge breakthrough. It could tell us if there was life on Mars at any point and it could cave the way to other things. A huge dream of mine, (though unlikely to be achieved as I'm near-sighted and I heard you have to have 20-20 vision to go on space exploration) is to go to Mars one day.

Yeah, I'd imagine there'd be a much wider range of geological strata available to sample at the final destination. If they do find evidence of life, it'd undoubtedly be one of the biggest discoveries in human history. Either possibility of Martian life sharing a common origin with its brethren on Earth or emerging independently is mindblowing.

I couldn't think of a bigger discovery tbh.

And IF it developed separately.....then wow at those implications of the capability of the universe supporting life, let alone this solar system.....but if we share the same DNA, then just as much wow as well, but in another way, in answering the age old question about how life started on earth.....although, it'd be a bit unsatisfying because it would simply shift the question to Mars, from Earth...but still would be an amazing piece of knowledge for us to absorb.

Ugh, I hate that I love this stuff so much and I my need for answers naow. ;)

I couldn't think of a bigger discovery tbh.

And IF it developed separately.....then wow at those implications of the capability of the universe supporting life, let alone this solar system.....but if we share the same DNA, then just as much wow as well, but in another way, in answering the age old question about how life started on earth.....although, it'd be a bit unsatisfying because it would simply shift the question to Mars, from Earth...but still would be an amazing piece of knowledge for us to absorb.

Ugh, I hate that I love this stuff so much and I my need for answers naow. ;)


While this is new evidence of water flowing on mars ,it is not the first , the mars reconnaissance orbiter had taken images of past water flows on mars a year ago <_<

I believe we are placing limits on the existence of life apart from us in the universe when we presume it is similiar to life as we know it .
what if other life is not carbon based ?
you are right , this is the question that fascinates me the most , and the one i would like to see an answer in the affirmative before i die

Not so moist Mars: Clays may come from lava, not lakesHunting for Martians may be a tougher task than predicted. Clays, long thought to be a sure sign of a warmer and wetter past on the Red Planet, could merely signal earlier volcanic activity – which would have made some regions on Mars less favourable for life.
Clay layers found across Mars suggest that during the Noachian period, from about 4.2 billion to 3.5 billion years ago, the planet was warm enough to host liquid water – necessary for life as we know it.
Scientists thought Mars clays could have formed in one of two ways: through soil interacting with standing water on the surface, or from water bubbling up from below via hydrothermal vents.
"Both of those would have created habitats that would have supported microbes," says study co-author Bethany Ehlmann of the California Institute of Technology in Pasadena. "On Earth, microbes would have been thriving away, enjoying themselves."
Thick history

But a new analysis of Martian meteorites hints that some clays may not have formed the way we think.
Alain Meunier of the University of Poitiers in France has found that some Mars minerals from the Noachian period are a good chemical match to clays at the Mururoa Atoll in French Polynesia, which formed from cooling of water-rich lava.
What's more, these ancient Martian clays can be up to hundreds of metres thick, which is more likely to be associated with lava flows than soil interacting with water.
"Such a result would imply that early Mars may not have been as habitable as previously thought at the time when Earth's life was taking hold," wrote Brian Hynek of the University of Colorado in Boulder, who was not involved in the new work, in an accompanying commentary.
Tastes of lava

One way to confirm where Mars clays came from is to check the soil texture with a high-resolution microscope.
"Under each of those scenarios, there are particular characteristics of texture," Ehlmann says.
NASA's Curiosity rover has spent about a month in Gale Crater near the Martian equator, which holds a wealth of clay minerals. Curiosity has an onboard microscope, but it's not quite good enough to make the distinction.
Another option would be to do chemical analyses and look for certain rare-earth elements. But that would require a mission capable of returning pristine samples to Earth.
Still, Ehlmann is not worried about Curiosity's chances of finding clays made by liquid water. Gale Crater's morphology – the fact that "it was a big deep hole in the ground" – fits better with the theory that it was a lake, not a volcano.
"I think Gale is a different flavour of Mars," Ehlmann says. "If we wanted to test out this hypothesis, we'd head elsewhere."

In a way you're right, however, this is the first direct evidence of flowing water, confirming the previous evidence as you kindly put up about previous 'water flow' imaging from space. The other evidence was open to possibly other explanations like magma flow from volcanoes, even if that was a remote chance with some of the images.

Confirmation is key, and that's the what we received, and that's the really awesome part. There's no doubt now.

Well, Einstein's discoveries of relativity and mass and energy being interchangeable would be at least on the same level, IMO.

Personally, I'd find the possibility of hypothetical life on Mars having an independent origin to be the more exciting possiblity. If life can arise independently at least twice in the same solar system, what does that say about its prevalence in the rest of the universe? That being said, finding out that our lineage began on another planet would be amazing in its own right.

Wonder how the various religions will adapt if we discover life on another planet.

They will rationalise it so it fits in their belief system , thats what so many human being's do.

But I wonder if the Theory of Relativity had the same implications for the average person, and therefore the larger population as the simple but profound knowledge that 'we are not alone'.

Somehow that seems to have a resonance that perhaps Relativity may not. I think everyone on the planet at one time in their lives will ask, "Are we alone out here?"....but i'm not sure if everyone will ask or think to ask about how measurements of various quantities are relative to the velocities of observers, or how energy is related to mass. ;)

I don't knock the profundity of ToR though....not in the least.
