Story and mosaics updated[/caption]

NASA’s most scientifically powerful rover ever dispatched to the Red Planet, Curiosity, is celebrating her 2nd anniversary on Mars since the dramatic touchdown inside Gale Crater on Aug. 6, 2012, EDT (Aug. 5, 2012, PDT) while simultaneously approaching a bedrock unit that for the first time is actually part of the humongous mountain she will soon scale and is the primary science destination of the mission.

Mount Sharp is a layered mountain that dominates most of Gale Crater and towers 3.4 miles (5.5 kilometers) into the Martian sky and is taller than Mount Rainier.

Aug. 6, 2014 marks ‘2 Years on Mars’ and Sol 711 for Curiosity in an area called “Hidden Valley.”

“Getting to Mount Sharp is the next big step for Curiosity and we expect that in the Fall of this year,” Dr. Jim Green, NASA’s Director of Planetary Sciences at NASA Headquarters, Washington, DC, told me in an interview making the 2nd anniversary.

The 1 ton rover is equipped with 10 state-of-the-art science instruments and searching for signs of life.

The mysterious mountain is so huge that outcrops of bedrock extend several miles out from its base and Curiosity is now within striking distance of reaching the area the rover team calls “Pahrump Hills.”

Scientists anticipate that the outcrops at “Pahrump Hills” offer a preview of a geological unit that is part of the base of Mount Sharp for the first time since landing rather than still belonging to the floor of Gale Crater.

“We’re coming to our first taste of a geological unit that’s part of the base of the mountain rather than the floor of the crater,” said Curiosity Project Scientist John Grotzinger of the California Institute of Technology, Pasadena, in a statement.

“We will cross a major terrain boundary.”

Since “Pahrump Hills” is less than one-third of a mile (500 meters) from Curiosity she should arrive soon.

In late July 2014, the rover arrived in an area of sandy terrain called “Hidden Valley” which is on the planned route ahead leading to “Pahrump Hills” and easily traversable with few of the sharp edged rocks that have caused significant damage to the rovers six aluminum wheels.

The sedimentary layers in the lower slopes of Mount Sharp have been Curiosity’s long-term science destination.

They are the principal reason why the science team specifically chose Gale Crater as the primary landing site based on high resolution spectral observations collected by NASA’s powerful Mars Reconnaissance Orbiter (MRO) indicating the presence of deposits of clay-bearing sedimentary rocks.

Curiosity’s goal all along has been to determine whether Mars ever offered environmental conditions favorable for microbial life. Finding clay bearing minerals. or phyllosilicates, in Martian rocks is the key to fulfilling its major objective.

The team expected to find the clay bearing minerals only in the sedimentary layers at the lower reaches of Mount Sharp.

Soon after landing, the team spotted some rather interesting looking outcrops barely a half mile away from the touchdown zone at a spot dubbed ‘Yellowknife Bay” and decided to take a detour towards it to investigate.

Well the scientists won the bet and struck scientific gold barely six months after landing when they drilled into a rock outcrop named “John Klein” at “Yellowknife Bay” and unexpectedly discovered the clay bearing minerals on the crater floor.

Yellowknife Bay was found to be an ancient lakebed where liquid water flowed on Mars surface billions of years ago.

The discovery of phyllosilicates in the 1st drill sample during the spring of 2013 meant that Curiosity had rather remarkably already fulfilled its primary goal of finding a habitable zone during its first year of operations!

The rock analysis “yielded evidence of a lakebed environment billions of years ago that offered fresh water, all of the key elemental ingredients for life, and a chemical source of energy for microbes, if any existed there,” according to NASA.

Curiosity accomplished Historic 1st drilling into Martian rock at John Klein outcrop on Feb 8, 2013 (Sol 182) and discovered a habitable zone, shown in this context mosaic view of the Yellowknife Bay basin taken on Jan. 26 (Sol 169).

“Before landing, we expected that we would need to drive much farther before answering that habitability question,” said Curiosity Project Scientist John Grotzinger of the California Institute of Technology, Pasadena. “We were able to take advantage of landing very close to an ancient streambed and lake. Now we want to learn more about how environmental conditions on Mars evolved, and we know where to go to do that.”

During the rovers second Earth year on the Red Planet, Curiosity has been driving as fast as possible towards a safe entry point to the slopes of Mount Sharp. The desired destination for the car sized rover is now about 2 miles (3 kilometers) southwest of its current location.

‘Driving, Driving, Driving’ is indeed the rover teams mantra.

To date, Curiosity’s odometer totals over 5.5 miles (9.0 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 174,000 images.

Curiosity still has about another 2 miles (3 kilometers) to go to reach the entry way at a gap in the treacherous sand dunes at the foothills of Mount Sharp sometime later this year.

And NASA is moving forward with future Red Planet missions when it recently announced the selection of 7 instruments chosen to fly aboard the Mars 2020 rover, the agency’s next rover going to Mars that will search for signs of ancient life as well as carry a technology demonstration that will help pave the way for ‘Humans to Mars’ in the 2030s. Read my story – here.

Coincidentally, ESA’s Rosetta comet hunting spacecraft arrived in orbit at its destination Comet 67P after a 10 year voyage on the same day as Curiosity’s 2 Earth year anniversary.

Sparks Fly on Mars as Curiosity Laser Blasts Red Planet Rock – Photos/Video

Curiosity has zapped hundreds of Red Planet rocks with her powerful laser blaster during her lifetime and has now caught the sparks flying for the first time as they happened – as seen in new photos and video above and below released this week by NASA.

As the NASA rover’s million watt Chemistry and Camera (ChemCam) instrument fired multiple laser shots at a rock fortuitously named “Nova” the team commanded her arm-mounted Mars Hand Lens Imager (MAHLI) high resolution imaging camera to try and capture the action as it occurred, for the first time. And they succeeded.

Curiosity blasted the baseball sized “Nova” rock target over 100 times on July 12, 2014, or Sol 687.

Since the nail biting touchdown nearly two years ago on Aug. 5, 2012 inside Gale Crater, ChemCam has aimed the laser instrument at more than 600 rock or soil targets and fired more than 150,000 laser shots.

Here’s a NASA/JPL video showing the laser flash:

Video Caption: The sparks that appear on the baseball-sized rock (starting at :17) result from the laser of the ChemCam instrument on NASA’s Curiosity Mars rover hitting the rock. Credit: NASA/JPL-Caltech/MSSS

ChemCam is used to determine the composition of Martian rocks and soils at a distance of up to 25 feet (8 meters) yielding preliminary data for the scientists and engineers to decide if a target warrants up close investigation and in rare cases sampling and drilling activities.

ChemCam works through a process called laser-induced breakdown spectroscopy. The laser hits a target with pulses to generate sparks, whose spectra provide information about which chemical elements are in the target.

Successive laser shots are fired in sequence to gradually blast away thin layers of material. Each shot exposes a slightly deeper layer for examination by the ChemCam spectrometer.

As Curiosity fired deeper into “Nova” it showed an increasing concentration of aluminum as the sequential laser blasts penetrated through the uninteresting dust on the rock’s surface. Silicon and sodium were also detected.

“This is so exciting! The ChemCam laser has fired more than 150,000 times on Mars, but this is the first time we see the plasma plume that is created,” said ChemCam Deputy Principal Investigator Sylvestre Maurice, at the Research Institute in Astrophysics and Planetology, of France’s National Center for Scientific Research and the University of Toulouse, France, in a statement.

“Each time the laser hits a target, the plasma light is caught and analyzed by ChemCam’s spectrometers. What the new images add is confirmation that the size and shape of the spark are what we anticipated under Martian conditions.”

A Martian target rock called "Nova," shown here, displayed an increasing concentration of aluminum as a series of laser shots from NASA's Curiosity Mars rover penetrated through dust on the rock's surface. This pattern is typical of many rocks examined with the rover's laser-firing ChemCam.

The SUZ sized rover is driving as swiftly as possible to the base of Mount Sharp which dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

During Year 1 on Mars, Earth’s emissary has already accomplished her primary objective of discovering a habitable zone on the Red Planet that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

To date, Curiosity’s odometer totals over 5.1 miles (8.4 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 166,000 images.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the treacherous sand dunes at the foothills of Mount Sharp sometime later this year.

Rock On! Curiosity Spots a Heavy Metal Meteorite

2-meter wide iron meteorite dubbed "Lebanon," as imaged by Curiosity's ChemCam and Mastcam on May 25, 2014

Talk about heavy metal! This shiny, lumpy rock spotted by NASA’s Curiosity rover is likely made mostly of iron — and came from outer space! It’s an iron meteorite, similar to ones found in years past by Curiosity’s forerunners Spirit and Opportunity, but is considerably larger than any of the ones the MER rovers came across… in fact, at 2 meters (6.5 feet) wide this may very well be the biggest meteorite ever discovered on Mars!

Click the image for a supermetallicious high-resolution version from JPL’s Planetary Photojournal.

Original raw Mastcam (right) image of Lebanon and Lebanon B from Sol 640 (NASA/JPL-Caltech/MSSS)

The picture above was made by combining high-resolution circular images (outlined in white) acquired with the Remote Micro-Imager (RMI) of Curiosity’s ChemCam instrument with color and context from the rover’s Mastcam. The images were taken on mission Sol 640 (May 25, 2014) and have been adjusted to simulate more Earth-like illumination.

Dubbed “Lebanon,” the large meteorite has a smaller fragment lying alongside it, named “Lebanon B.”

While iron meteorites are fairly common on Earth, on Mars they are by far the most common types of meteorites that have been discovered — if just for the sheer fact that they are highly resistant to erosion.*

*Note: that isn’t to say iron meteorites can’t be eroded; on the contrary, much of their signature surface sheen and pitted texture comes from various erosion processes. See a related study from J. W. Ashley et al. here.

Fancy a little Mars in your daily life? You need go no further than the excellent raw image archive that NASA generously provides on its website, showing the view from the Opportunity and Curiosity rovers as they make their way on the surface.

Opportunity is rolling along in its eleventh year of operations, busily exploring the west rim of Endeavour Crater. Below the jump is a stunning stitch-together of some of its latest images from space tweep Stu Atkinson, who runs a lovely blog called Road to Endeavour about the rover’s adventures. NASA also has an official blog that was last updated July 1.

The Curiosity rover is in Gale Crater near the Martian equator, heading towards Mount Sharp as NASA picks paths that are the softest for its damaged wheels. Panorama maker Andrew Bodrov recently put together a new 360-degree view of Curiosity’s mastcam, which encompasses 137 images taken on Sol 673. You can see that below the jump as well.

Curiosity Captured from Orbit Crossing Landing Ellipse Boundary – Martian Scenery from Above and Below

This June 27, 2014, image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows NASA's Curiosity Mars rover on the rover's landing-ellipse boundary, which is superimposed on the image. The 12-mile-wide ellipse was mapped as safe terrain for its 2012 landing inside Gale Crater. Image Credit: NASA/JPL-Caltech/Univ. of Arizona

NASA has now released a breathtaking high resolution image of the rover Curiosity captured from Mars orbit coincidentally coinciding with her crossing the targeted landing ellipse just days after she marked ‘1 Martian Year’ on the Red Planet in search of the chemical ingredients necessary to support alien microbial life forms.

The orbital image was taken on June 27 (Sol 672) by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO) and clearly shows the rover and wheel tracks at the end of the drive that Sol, or Martian day.

You can simultaneously experience the Martian eye view of Curiosity from above and below by checking out our Sol 672 ground level photo mosaic – below. It’s assembled from raw images taken by the mast mounted navigation camera (Navcam) showing the rovers wheel tracks and distant rim of the Gale Crater landing site.

The six wheeled robot drove about 269 feet (82 meters) on June 27 traversing to the boundary of her targeted landing ellipse in safe terrain – approximately 4 miles wide and 12 miles long (7 kilometers by 20 kilometers) – for the first time since touchdown on Mars nearly two years ago on August 5, 2012 inside Gale Crater.

Curiosity celebrated another Martian milestone anniversary on June 24 (Sol 669) – 1 Martian Year on Mars!

A Martian year is equivalent to 687 Earth days, or nearly two Earth years.

To date, Curiosity’s odometer totals over 5.1 miles (8.4 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 165,000 images.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the treacherous sand dunes at the foothills of Mount Sharp sometime later this year.

Trekking Mars – Curiosity Roves Outside Landing Ellipse!

Trekking Mars – NASA’s intrepid robot Curiosity is roving rapidly across the sandy ripples of the Red Planet in her quest to reach mysterious Mount Sharp and just drove outside her landing ellipse!

The six wheeled rover marked a major milestone on Sol 672, June 27, 2014, by traversing beyond her targeted landing ellipse for the first time since touchdown on Mars nearly two years ago on August 5, 2012.

“On yestersol’s drive [June 27], I left my landing ellipse—the 20×25 km area I targeted for landing,” Curiosity tweeted across interplanetary space.

See our new Sol 672 photo mosaic above showing Curiosity’s glorious view marking this major achievement just days ago.

Since switching paths to smoother, sandier terrain with less sharp edged rocks, Curiosity continues rolling across the floor of her Gale Crater landing site, pausing occasionally for potentially dicey dunes.

“After traversing 82 meters the rover stopped because it determined that it was slipping too much,” wrote mission scientist Ken Herkenhoff in an update.

“Coincidentally, the rover stopped right on the landing ellipse, a major mission milestone!”

“The vehicle was designed to be able to traverse far enough to drive out of the region defined by the uncertainty in the landing location, and has now achieved that laudable goal,” Herkenhoff confirmed.

The SUV sized rover automatically stopped when it encountered soft sand and sensed that it wasn’t making enough progress. It’s been programmed with this built in safety check to avoid being trapped in a quagmire of quicksand.

Earlier last week, Curiosity celebrated another milestone anniversary on June 24 (Sol 669) – 1 Martian Year on Mars!

A Martian year is equivalent to 687 Earth days, or nearly two Earth years.

See our Sol 669 photo mosaic marking 1 Mars Year on Mars – above.

So there’s no stopping Curiosity on her way to Mount Sharp, which dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

Driving, Driving, Driving – that’s Curiosity’s number one priority as she traverses across the surface of Gale Crater towards towering Mount Sharp on an expedition in search of the chemical ingredients of life that could support Martian microbes if they ever existed.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

To date, Curiosity’s odometer totals over 5.1 miles (8.4 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 162,000 images.

NASA’s Curiosity rover celebrated a milestone anniversary today, June 24 – 1 Martian Year on Mars!

A Martian year is equivalent to 687 Earth days, or nearly two Earth years.

NASA marked the illustrious achievement with the release of a new ‘selfie’ captured recently while drilling deep into the Red Planet to unlock the secrets of Mars hidden past eons ago when the planet was far warmer and wetter and more conducive to the origin of life.

Curiosity’s new self-portrait was taken at the ‘Windjana’ Drilling Site in April and May 2014 using the Mars Hand Lens Imager (MAHLI) camera at the end of the robotic arm.

As of today the 1 ton rover has been exploring the alien surface for a full Martian year since her nail biting touchdown inside Gale Crater on Aug. 5, 2012 – using the unprecedented sky crane maneuver which culminated in a rocket assisted touchdown astride a humongous mountain named Mount Sharp.

Mount Sharp dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

During Mars Year 1 on Mars, Earth’s metallic emissary has already accomplished her primary objective of discovering a habitable zone on the Red Planet that contains the chemical ingredients necessary to support microbial life in the ancient past.

During 2013, Curiosity conducted the first two drill campaigns at the ‘John Klein’ and ‘Cumberland’ outcrop targets inside Yellowknife Bay. They were both mudstone rock outcrops and the interiors were markedly different in color and much lighter compared to the new drill site at ‘Windjana’ into a slab of red, sandstone rock.

The fresh bore hole was drilled into the “Windjana” rock outcrop on May 5, 2014, Sol 621, at the base of Mount Remarkable at a science stopping point called “The Kimberley Waypoint.”

It was 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.5 centimeters) deep and resulted in a mound of dark grey colored drill tailings piled around.

Windjana lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay.

Curiosity has successfully delivered pulverized and sieved samples from all three drill sites to the pair of onboard miniaturized chemistry labs; the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars instrument (SAM) – for chemical and compositional analysis.

It was through the results of the SAM and CheMin analysis and the discovery of clay minerals that the science team was able to determine that this area on the floor of Gale Crater is a habitable zone.

“Windjana has more magnetite than previous samples we’ve analyzed,” said David Blake, principal investigator for Curiosity’s Chemistry and Mineralogy (CheMin) instrument at NASA’s Ames Research Center, Moffett Field, California, in a statement.

“A key question is whether this magnetite is a component of the original basalt or resulted from later processes, such as would happen in water-soaked basaltic sediments. The answer is important to our understanding of habitability and the nature of the early-Mars environment.”

Chemical analysis and further sample deliveries are in progress as NASA’s rover is ‘on the go’ to simultaneously maximize movement and research activities.

The lower reaches of Mount Sharp are the rovers ultimate goal because the sedimentary layers are believed to hold caches of water altered minerals based on high resolution measurements obtained by the CRISM spectrometer aboard NASA’s powerful Martian ‘Spysat’ – the Mars Reconnaissance Orbiter (MRO) – soaring overhead.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

Driving, Driving, Driving – Curiosity’s Top Priority on the Road to Mysterious Mount Sharp

Driving, Driving, Driving – that’s the number one priority for NASA’s rover Curiosity as she traverses across the floor of Gale Crater towards towering Mount Sharp on an expedition in search of the chemical ingredients of life that could support Martian microbes if they ever existed.

See our photo mosaics above and below showing the 1 ton rover trundling across the alien terrain of Mars – our Solar Systems most Earth-like planet and leaving behind dramatic wheel tracks in her wake.

“The top priority for MSL continues to be the traverse toward the base of Mt. Sharp,” wrote science team member Ken Herkenhoff in a mission update.

Curiosity has been on the move since mid-May after successfully completing her 3rd Martian drill campaign at a science stopping point called “The Kimberley” where she bored a fresh hole into the ‘Windjama’ rock target on May 5, Sol 621 at the base of Mount Remarkable.

“Progress has been good since leaving The Kimberley,” Herkenhoff added.

Investigating mysterious Mount Sharp is why Gale Crater was chosen as the landing site because the mountain holds clues to the habitability of the Red Planet.

Mars was far wetter and warmer – and more conducive to the origin of life – billions of years ago.

The six-wheeled rover has been traveling with all deliberate speed to get to the mountain with minimal science along the way.

“[Curiosity conducted] a 129-meter drive on Sol 662 (June 17),” says Herkenhoff.

“We successfully planned a rapid traverse sol last week, in which scientific observations are limited in favor of maximizing drive distance.”

Curiosity is driving on a path towards the ‘Murray Buttes’ – which lies across the dark and potentially treacherous dunes on the right side of Mount Sharp as seen in our photo mosaic above from Sol 651.

She will eventually ascend the mountain at the ‘Murray Buttes’ after the team locates a spot to carefully cross the sand dunes.

The fresh hole drilled into “Windjana” was 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.5 centimeters) deep and resulted in a mound of dark grey colored drill tailings piled around. It looked different from the initial two holes drilled at Yellowknife Bay in the spring of 2013.

Windjana was a cold red slab of enticing bumpy textures of Martian sandstone located at the base of ‘Mount Remarkable’ within the “The Kimberley Waypoint” region.

The first two drill campaigns involved boring into mudstone outcrops at Yellowknife Bay.

Windjana lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay.

Curiosity then successfully delivered pulverized and sieved samples to the pair of onboard miniaturized chemistry labs; the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars instrument (SAM) – for chemical and compositional analysis.

Chemical analysis and further sample deliveries are in progress as NASA’s rover is ‘on the go’ to simultaneously maximize movement and research activities.

The science and engineering team has deliberately altered the robots path towards the foothills of Mount Sharp which reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Ranier.

The team decided to follow a new path to the mountain with smoother terrain after sharp edged rocks caused significant damage in the form of dents and holes to the robots 20 inch wide aluminum wheels.

The wheel punctures happened faster than expected in 2013 and earlier this year.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

To date, Curiosity’s odometer totals over 7.9 kilometers (4.9 miles) since landing inside Gale Crater on Mars in August 2012. She has taken over 159,000 images.

Stay tuned here for Ken’s continuing Curiosity, Opportunity, Orion, SpaceX, Boeing, Orbital Sciences, commercial space, MAVEN, MOM, Mars and more planetary and human spaceflight news.

Curiosity Captures Mercury from Mars

Image of the Sun as seen from Mars by Curiosity. Mercury is the circled dark spot.

NASA’s Curiosity rover may be busy exploring the rugged and rocky interior of Gale Crater, but it does get a chance to skygaze on occasion. And while looking at the Sun on June 3, 2014 (mission Sol 649) the rover’s Mastcam spotted another member of our Solar System: tiny Mercury, flitting across the Sun’s face.

Silhouetted against the bright disk of the Sun, Mercury barely appears as a hazy blur in the filtered Mastcam images. But it was moving relatively quickly during the transit, passing the darker smudges of two Earth-sized sunspots over the course of several hours.

It’s the first time Mercury has ever been imaged from Mars, and also the first time we’ve observed a planet transiting our Sun from another world besides our own.

Watch an animation of the transit below:

Because the sunspots move along with the rotation of the Sun (and the Sun rotates once avery 25 days around its equator) Mercury makes a fast pass as it travels along on one of its 88-day-long years.

Watch an HD version of the event here.

In reality this was no chance spotting, but rather a carefully calculated observation using the Mastcam’s right 100mm telephoto lens and neutral density filter, which is used to routinely image the Sun in order to measure the dustiness of the Martian atmosphere.

“This is a nod to the relevance of planetary transits to the history of astronomy on Earth. Observations of Venus transits were used to measure the size of the solar system, and Mercury transits were used to measure the size of the sun.”

– Mark Lemmon, Texas A&M University, member of the Mastcan science team

The next chance for Curiosity to spot Mercury will come in April 2015 and, if the rover is still operating by then — perhaps with some upgrades by future human visitors? — it may capture Earth similarly passing across the Sun in November of 2084.

Curiosity Captures Stunning New Mount Sharp Panorama ‘On The Go’

Story updated[/caption]

Within the past Martian day on Friday, June 6, NASA’s rover Curiosity captured a stunning new panorama of towering Mount Sharp and the treacherous sand dunes below which she must safely traverse before reaching the mountains foothills – while ‘On The Go’ to her primary destination.

See our brand new Mount Sharp photo mosaic above – taken coincidentally by humanity’s emissary on Mars on the 70th anniversary of D-Day on Earth.

Basically she’s eating desiccated dirt while running a Martian marathon.

Having said ‘Goodbye Kimberley’ after drilling her third bore hole deep into a cold red slab of enticing bumpy textures of Martian sandstone in the name of science, our intrepid mega rover Curiosity is trundling along with all deliberate speed towards the inviting slopes of sedimentary rocks at the base of mysterious Mount Sharp which hold clues to the habitability of the Red Planet.

The sedimentary layers of Mount Sharp, which reaches 3.4 miles (5.5 km) into the Martian sky, is the six wheeled robots ultimate destination inside Gale Crater because it holds caches of water altered minerals.

Such minerals could possibly mark locations that sustained potential Martian microbial life forms, past or present, if they ever existed.

Mars was far wetter and warmer – and more conducive to the origin of life – billions of years ago.

The 1 ton robot is driving on a path towards the Murray Buttes which lies across the dunes on the right side of Mount Sharp as seen in our photo mosaic above, with wheel tracks on the left side.

She will eventually ascend the mountain at the ‘Murray Buttes’ after crossing the sand dunes.

Curiosity still has roughly another 4 kilometers of driving to go to reach the foothills of Mount Sharp sometime later this year.

Approximately four weeks ago, Curiosity successfully completed her 3rd drilling campaign since landing at the science waypoint region called “The Kimberley” on May 5, Sol 621, into the ‘Windjana’ rock target at the base of a 16 foot tall ( 5 Meter) hill called Mount Remarkable.

The fresh hole drilled into “Windjana” was 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.5 centimeters) deep and resulted in a mound of dark grey colored drill tailings piled around. It looked different from the initial holes drilled at Yellowknife Bay in the spring of 2013.

Windjana lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay.

Before departing, Curiosity blasted the hole multiple times with her million watt laser on the Mast mounted Chemistry and Camera (ChemCam) instrument , leaving no doubt of her capabilities or intentions.

And she completed an up close examination of the texture and composition of ‘Windjana’ with the MAHLI camera and spectrometers at the end of her 7-foot-long (2 meter) arm to glean every last drop of science before moving on.

“Windjana” is named after a gorge in Western Australia.

While ‘On the Go’ to Mount Sharp, the rover is keeping busy with science activities by investigating the newly cored Martian material.

“Inside Curiosity we continue to analyse the Kimberley samples with CheMin and SAM,” wrote mission team member John Bridges in an update.

To date, Curiosity’s odometer totals 3.8 miles (6.1 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 154,000 images.

Stay tuned here for Ken’s continuing Curiosity, Opportunity, Orion, SpaceX, Boeing, Orbital Sciences, commercial space, MAVEN, MOM, Mars and more planetary and human spaceflight news.
