Curiosity Snaps Stunning One of a Kind Belly Selfie At Buckskin Mountain Base Drill Site

This low-angle self-portrait of NASA’s Curiosity Mars rover shows the vehicle at the site from which it reached down to drill into a rock target called “Buckskin.” The MAHLI camera on Curiosity’s robotic arm took multiple images on Aug. 5, 2015, that were stitched together into this selfie.

NASA’s Curiosity rover has snapped a stunningly beautiful, one of a kind ‘belly selfie’ amidst the painstaking ‘Buckskin’ drill campaign at the Martian mountain base marking the third anniversary since her touchdown on the Red Planet.

The unique self portrait was taken from a low-angle for the first time and shows the six wheeled rover at work collecting her seventh drilled sample at the ‘Buckskin’ rock target earlier this month in the “Marias Pass” area of lower Mount Sharp.

‘Buckskin’ is also unique in a fabulously scientifically way because the rover discovered a new type of Martian rock that’s surprisingly rich in silica – and unlike any other targets found before.

The low camera angle is what enables the awesome Buckskin belly selfie. It’s a distinctively dramatic view and actually stitched from 92 images captured by the Mars Hand Lens Imager (MAHLI) on Aug. 5, 2015, or Sol 1065 of the mission.

The high resolution MAHLI color camera is located on the end of the 7 foot-long (2.1 meter-long) robotic arm.

Indeed the car-sized rover has taken spectacular selfies several times before during her three year long trek across the Martian surface, since the August 2012 landing inside Mars’ Gale Crater. But for those past selfies the MAHLI camera was hoisted higher to give the perspective of looking somewhat downward and showing the rovers top deck and trio of sample inlet ports.

In this case, the rover team specifically commanded Curiosity to position “the camera lower in relation to the rover body than for any previous full self-portrait of Curiosity,” said NASA officials.

Two patches of gray colored powdered rock material drilled from Buckskin are visible in the selfie scene, in front of the rover.

“The patch closer to the rover is where the sample-handling mechanism on Curiosity’s robotic arm dumped collected material that did not pass through a sieve in the mechanism. Sieved sample material was delivered to laboratory instruments inside the rover. The patch farther in front of the rover, roughly triangular in shape, shows where fresh tailings spread downhill from the drilling process.”

Prior selfies were taken at the “Rocknest” (http://photojournal.jpl.nasa.gov/catalog/PIA16468), “John Klein” (http://photojournal.jpl.nasa.gov/catalog/PIA16937), “Windjana” (http://photojournal.jpl.nasa.gov/catalog/PIA18390) and “Mojave” drill sites.

Basically in the Sol 1065 belly selfie at “Buckskin” we see the underbelly of the rover and all six wheels along with a complete self portrait.

On several prior occasions, MAHLI was used to image just the underbelly and wheels to aid in inspecting the wheels to look for signs of damage inflicted by sharp-edged Martian rocks poking holes in the aluminum wheels.

Each wheel measures 20 inches (50 centimeters) in diameter and about 16 inches (40 centimeters) wide. And the MAHLI monitoring images have shown the effects of increasing wear and tear that ultimately forced the rover drivers to alter Curiosity’s driving route on the crater floor in favor of smoother and less rocky terrain imparting less damage to the critical wheels.

If you take a close look at the new selfie up top, you’ll see a small rock stuck onto Curiosity’s left middle wheel (on the right in this head-on view). The rock was seen also in prior wheel monitoring images taken three weeks ago.

“The selfie at Buckskin does not include the rover’s robotic arm beyond a portion of the upper arm held nearly vertical from the shoulder joint. With the wrist motions and turret rotations used in pointing the camera for the component images, the arm was positioned out of the shot in the frames or portions of frames used in this mosaic,” according to officials.

The drilling campaign into “Buckskin” was successfully conducted on Sol 1060 (July 30, 2015) at the bright toned “Lion” outcrop to a full depth of about 2.6 inches (6.5 centimeters) and approximately 1.6 cm (0.63 inch) diameter.

India’s space agency has released a spectacular new batch of images taken by everyone’s favorite MOM – the Mars Orbiter Mission – the nation’s first probe ever dispatched to the Red Planet and which achieved orbit nearly a year ago.

The Indian Space Research Organization (ISRO) has published a beautiful gallery of images featuring a steep and stunning Martian canyon and the landing site of NASA’s Curiosity Mars Science Laboratory rover, and more.

The lead image was taken over the Ophir Chasma canyon on the Martian surface by the Mars Colour Camera aboard India’s Mars Orbiter Mission.

Ophir Chasma is a canyon in the Coprates quadrangle located at 4° south latitude and 72.5° west longitude. It is part of the Valles Marineris – the ‘Grand Canyon of Mars’ – and the largest known canyon in the Solar System.

The image was captured on July 19, 2015 from an altitude of 1857 kilometers (1154 miles). It has with a resolution of 96 meters.

The steep walled Ophir Chasma canyon contains many layers and the floors contain large deposits of layered materials, perhaps even sulfates.

Ophir Chasma is about 317 kilometers long and about 8 to 10 kilometers deep located near the center of Valles Marineris – see map below.

Valles Marineris stretches over 4,000 km (2,500 mi) across the Red Planet, is as much as 600 km wide and measures as much as 10 kilometers (6 mi) deep. It is nearly as wide as the United States.

Here’s an illuminating and magnificent 3D portrayal of Ophir Chasma created by Indian scientists that gives a sense of the canyons scale, sheer walls and cliffs and depth:

The newest images were snapped after the spacecraft exited the communications blackout encountered by all of Earth’s invasion fleet of Red Planet orbiters and rovers during the recent conjunction period when Mars was behind the sun during much of June.

See the prior image release from ISRO in my MOM story – here.

Here’s a wider view of Valles Marineris showing Ophir Chasma in a previously published MOM image from ISRO.

ISRO also released a delightful new image of Gale Crater and the surrounding vicinity.

Gale Crater is the landing site of NASA’s Curiosity rover. MOM took the image from an altitude of 9004 kilometers.

Gale Crater is home to humongous Mount Sharp, a mountain that rises 5.5 kilometers (3.4 miles) from the crater floor and is easily visible in the photo from MOM. The crater is 154 kilometers (96 mi) wide.

Curiosity is currently exploring the foothills of Mount Sharp around the top of the image – which shows a rather different perspective from what we’ve seen from prior familiar orbital imagery snapped by several NASA and ESA orbiters.

The 1 ton rover recently celebrated the 3rd anniversary since its nailbiting touchdown inside Gale crater. And the new wider angle image from MOM gives a fabulous sense of exactly why a highly precise landing was essential – otherwise it would have been doomed.

Curiosity recently drilled into the “Buckskin” target at an outcrop at the foothills of Mount Sharp. See the mountain in our ground level mosaic from the crater floor. And its kind of neat to actually imagine Curiosity sitting there while perusing MOM’s photo.

MOM’s goal is to study Mars atmosphere, surface environments, morphology, and mineralogy with a 15 kg (33 lb) suite of five indigenously built science instruments. It is also sniffing for methane, a potential marker for biological activity.

The Indian probe arrived just after NASA’s MAVEN Mars orbiter, the first mission specifically targeted to study Mars tenuous upper atmosphere and the escape rates of atmospheric constituents.

MOM swoops around Mars in a highly elliptical orbit whose nearest point to the planet (periapsis) is at about 421 km and farthest point (apoapsis) at about 76,000 km, according to ISRO.

It takes MOM about 3.2 Earth days or 72 hours to orbit the Red Planet.

MOM was launched on Nov. 5, 2013 from India’s spaceport at the Satish Dhawan Space Centre, Sriharikota, atop the nations indigenous four stage Polar Satellite Launch Vehicle (PSLV) which placed the probe into its initial Earth parking orbit.

The $73 million MOM mission was expected to last at least six months. In March, ISRO extended the mission duration for another six months since its healthy, the five science instruments are operating fine and it has sufficient fuel reserves.

Including MOM, Earth’s invasion fleet at the Red Planet numbers a total of seven spacecraft comprising five orbiters from NASA, ESA and ISRO as well as the sister pair of mobile surface rovers from NASA – Curiosity and Opportunity.

Story updated[/caption]

NASA’s Curiosity Mars Science Laboratory (MSL) rover has successfully drilled into the first high silica rock target on Mars after recently discovering this new type of rock that’s unlike any found before – as she is about to mark the 3rd anniversary since the hair-raising touchdown on the Red Planet.

The SUV-sized rover bored a full depth hole into a Mars outcrop at a target dubbed “Buckskin” as commanded by the mission team over the weekend, after first conducting a mini drill test to assess the safety of the intended drill campaign to sample the alien rock interior beneath the Martian crater floor.

“This morning, the MSL operations team was very happy to see that drilling into Buckskin was successful!” said Ken Herkenhoff, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

Confirmation of the success of the full depth drilling into “Buckskin” on Sol 1060 at the bright toned “Lion” outcrop came later after receipt of new high resolution images from the rover showing the approximately 1.6 cm (0.63 inch) diameter bore hole next to the initial mini hole test, along with the indicative residue of grey colored tailings from the Martian subsurface seen distributed around the new hole.

“Successful drilling at Buckskin!” added team member Professor John Bridges of the University of Leicester, England, in an update.

“Like the other drill holes this is showing how thin red Mars is,” Bridges elaborated.

Beneath a thin veneer of rusty red colored iron oxide, the Red Planet is remarkably grey as demonstrated by Curiosity’s prior drilling campaigns.

The hole was bored to a full depth of about 2.6 inches (6.5 centimeters) using the percussion drill on the terminus of the 7 foot-long (2.1 meter-long) robotic arm.

Buckskin was “chosen because this sedimentary horizon has some very high silica enrichments,” Bridges explains.

The findings of elevated levels of silicon as well as hydrogen were derived from data collected by Curiosity’s laser-firing Chemistry & Camera (ChemCam) and Dynamic Albedo of Neutrons (DAN) instruments on certain local area rocks.

Silica is a rock-forming compound containing silicon and oxygen, commonly found on Earth as quartz.

“High levels of silica could indicate ideal conditions for preserving ancient organic material, if present, so the science team wants to take a closer look,” say mission team officials.

See the rover at work reaching out with her robotic arm and drilling into Buckskin, as illustrated in our new mosaics of mastcam and navcam camera raw images created by the image processing team of Ken Kremer and Marco Di Lorenzo (above and below).

“Buckskin” sits at the base of Mount Sharp, a huge layered mountain that dominates the center of the 96 mile-wide (154 kilometers-wide) Gale Crater landing site.

Exploring the sedimentary layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, is the primary destination and goal of the rovers long term scientific expedition on the Red Planet.

The silica enrichment “may have occurred as the Gale sediments were altered by subsurface fluids after burial. As the basaltic composition was altered (as we saw from the clay and Fe oxide at Yellowknife Bay) ultimately a lot of silica is released which can be precipitated at horizons like this,” explains Bridges.

The Curiosity Mars Science Laboratory (MSL) rover safely touched down on the crater floor on August 5, 2012 following the unprecedented and nail-biting sky crane maneuver that delivered her with pinpoint precision to a landing site nearby Mount Sharp inside Gale Crater.

The goal of the drilling is to provide geologic context for Curiosity’s long term climb up the mountains sedimentary layers by collecting samples to assess the habitability of the Red Planet over billions of years of time.

So the plan was for the robot to process and pulverize the samples for eventual delivery to the onboard pair of miniaturized chemistry labs located inside her belly – SAM and CheMin. Tiny samples are fed to a trio of inlet ports on the rover deck through the sieved filters.

Images are taken to document and assess the entire sample collection and delivery process.

After gathering the Buckskin sample, a portion was transferred to the robots scoop for inspection.

Then the first portion was successfully fed into CheMin for inorganic elemental analysis over the weekend.

“The activities planned for last weekend completed successfully, including sample dropoff to CheMin and analysis of the minerals present,” Herkenhoff confirmed.

The one ton robots next steps involve “dumping the portion of the drill sample that has not been sieved and Mastcam, ChemCam, MAHLI, and APXS observations of the dump pile. ChemCam and Mastcam will also observe nearby targets “Martz” and “Mountain Home.” MAHLI will image the drill hole, tailings and CheMin inlet at night using its LEDs for illumination.”

After completing these science activities, the six wheeled rover will move on to the next exciting destination.

“It’s been a great couple of weeks at the Lion outcrop, but it’s time to move on,” says Lauren Edgar, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in the latest mission update from today, August 4, Sol 1065.

“After a successful investigation that included observations by almost every science instrument, we’re getting ready to drive away tomorrow. That means that today (and tomorrow before we drive) is the last call for science observations.”

For about the past two months, the six wheeled robot has been driving around and exploring a geological contact zone named “Marias Pass” – an area on lower Mount Sharp, by examining the rocks and outcrops with her suite of state-of-the-art science instruments.

“Marias Pass” is a geological context zone where two rock types overlap – pale mudstone meets darker sandstone.

The prior hole was drilled at Telegraph Peak on Feb. 24, 2015, on Sol 908.

Curiosity Discovers Mars Rock Like None Before, Sets Drill Campaign

On the eve of the 3rd anniversary since her nail biting touchdown inside Gale Crater, NASA’s car sized Curiosity Mars Science Laboratory (MSL) rover has discovered a new type of Martian rock that’s surprisingly rich in silica – and unlike any other targets found before.

Excited by this new science finding on Mars, Curiosity’s handlers are now gearing the robot up for her next full drill campaign today, July 31 (Sol 1060) into a rock target called “Buckskin” – which lies at the base of Mount Sharp, the huge layered mountain that is the primary science target of this Mars rover mission.

“The team selected the “Buckskin” target to drill,” says Lauren Edgar, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

“It’s another exciting day on Mars!”

See the rover at work reaching out with her robotic arm and drilling into Buckskin, as illustrated in our new mosaics of navcam camera images created by the image processing team of Ken Kremer and Marco Di Lorenzo (above and below). Also featured at Alive Universe Images – here.

The goal is to provide geologic context for her long term expedition up the mountains sedimentary layers to study the habitability of the Red Planet over eons of time.

Data from Curiosity’s “laser-firing Chemistry & Camera (ChemCam) and Dynamic Albedo of Neutrons (DAN), show elevated amounts of silicon and hydrogen, respectively,” in certain local area rocks, according to the team.

Silica is a rock-forming compound containing silicon and oxygen, commonly found on Earth as quartz.

“High levels of silica could indicate ideal conditions for preserving ancient organic material, if present, so the science team wants to take a closer look.”

Therefore the team scouted targets suitable for in depth analysis and sample drilling and chose “Buckskin”.

“Buckskin” is located among some high-silica and hydrogen enriched targets at a bright outcrop named “Lion.”

An initial test bore operation was conducted first to confirm whether that it was indeed safe to drill into “Buckskin” and cause no harm to the rover before committing to the entire operation.

The bore hole is about 1.6 cm (0.63 inch) in diameter.

“This test will drill a small hole in the rock to help determine whether it is safe to go ahead with the full hole,” elaborated Ryan Anderson, planetary scientist at the USGS Astrogeology Science Center and an MSL science team member.

So it was only after the team received back new high resolution imagery last night from the arm-mounted MAHLI camera which confirmed the success of the mini-drill operation, that the “GO” was given for a full depth drill campaign. MAHLI is short for Mars Hand Lens Imager.

“We successfully completed a mini drilling test yesterday (shown in the MAHLI image). That means that today we’re going for the FULL drill hole” Edgar confirmed.

“GO for Drilling.”

So it’s a busy day ahead on the Red Planet, including lots of imaging along the way to document and confirm that the drilling operation proceeds safely and as planned.

“First we’ll acquire MAHLI images of the intended drill site, then we’ll drill, and then we’ll acquire more MAHLI images after drilling,” Edgar explains.

“The plan also includes Navcam imaging of the workspace, and Mastcam imaging of the target and drill bit. In addition to drilling, we’re getting CheMin ready to receive sample in an upcoming plan. Fingers crossed!” Surface observations with the arm-mounted Alpha Particle X-ray Spectrometer (APXS) instrument are also planned.

If all goes well, the robot will process and pulverize the samples for eventual delivery to the onboard pair of miniaturized chemistry labs located inside her belly – SAM and CheMin. Tiny samples will be fed to the inlet ports on the rover deck through the sieved filters.

Meanwhile the team is studying a nearby rock outcrop called “Ch-paa-qn” which means “shining peak” in the native Salish language of northern Montana.”

Anderson says the target is a bright patch on a nearby outcrop. Via active and passive observations with the mast-mounted ChemCam laser and Mastcam multispectral imager, the purpose is to determine if “Ch-paa-qn” is comprised of calcium sulfate like other white veins visible nearby, or perhaps it’s something else entirely.

A rock fragment dubbed "Lamoose" is shown in this picture taken by the Mars Hand Lens Imager (MAHLI) on NASA's Curiosity rover. Like other nearby rocks in a portion of the "Marias Pass" area of Mt. Sharp, Mars, it has unusually high concentrations of silica. The high silica was first detected in the area by the Chemistry & Camera (ChemCam) laser spectrometer. This rock was targeted for follow-up study by the MAHLI and the arm-mounted Alpha Particle X-ray Spectrometer (APXS).

Before arriving by the “Lion” outcrop last week, Curiosity was investigating another outcrop area nearby, the high-silica target dubbed “Elk” with the ChemCam instrument, while scouting around the “Marias Pass” area in search of tasty science targets for in-depth analysis.

Sometimes the data subsequently returned and analyzed is so extraordinary, that the team decides on a return trip to a spot previously departed. Such was the case with “Elk” and the rover was commanded to do a U-turn to acquire more precious data.

“One never knows what to expect on Mars, but the Elk target was interesting enough to go back and investigate,” said Roger Wiens, the principal investigator of the ChemCam instrument from the Los Alamos National Laboratory in New Mexico.

Soon, ChemCam will have fired on its 1,000th target. Overall the laser blaster has been fired more than 260,000 times since Curiosity landed inside the nearly 100 mile wide Gale Crater on Mars on Aug. 6, 2012, alongside Mount Sharp.

“ChemCam acts like eyes and ears of the rover for nearby objects,” said Wiens.

“Marias Pass” is a geological context zone where two rock types overlap – pale mudstone meets darker sandstone.

The rover spotted a very curious outcrop named “Missoula.”

“We found an outcrop named Missoula where the two rock types came together, but it was quite small and close to the ground. We used the robotic arm to capture a dog’s-eye view with the MAHLI camera, getting our nose right in there,” said Ashwin Vasavada, the mission’s project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

White mineral veins, possibly comprised of calcium sulfate, filled the fractures by depositing the mineral from running groundwater.

“Such clues help scientists understand the possible timing of geological events,” says the team.

India’s first ever robotic explorer to the Red Planet, the Mars Orbiter Mission, more affectionately known as MOM, has captured an absolutely dazzling array of images of the fourth rock from the Sun.

The Indian Space Research Organization (ISRO), India’s space agency, has recently published a beautiful gallery of images featuring a variety of picturesque Martian canyons, volcanoes, craters, moons and more.

We’ve gathered a collection here of MOM’s newest imagery snapped by the probes Mars Color Camera (MCC) for the enjoyment of Martian fans worldwide.

The spectacular 3D view of the Arsia Mons volcano, shown above, was “created by draping the MCC image on topography of the region derived from the Mars Orbiter Laser Altimeter (MOLA), one of five instruments on board NASA’s Mars Global Surveyor (MGS) spacecraft.

The Arsia Mons image was taken from Mars orbit on 1 April 2015 at a spatial resolution of 556 meters from an altitude of 10707 km. Volcanic deposits can be seen located at the flanks of the Mons, according to ISRO.

The view of Pital crater below was released in late May and taken on 23 April 2015. Pital is a 40 km wide impact crater located in the Ophir Planum region of Mars and the image shows a chain of small impact craters. It is located in the eastern part of Valles Marineris region, says an ISRO description. MCC took the image from an altitude of 808 km.

It is an odd shaped crater, neither circular nor elliptical in shape, possibly due to “regional fracture in the W-E trending fracture zone.”

Valles Marineris stretches over 4,000 km (2,500 mi) across the Red Planet , is as much as 600 km wide and measures as much as 7 kilometers (4 mi) deep.

For context here’s a previously taken global image of the red planet from MOM showing Valles Marinaris and Arsia Mons, which belongs to the Tharsis Bulge trio of shield volcanoes. They are both near the Martian equator.

Valles Marineris is often called the “Grand Canyon of Mars.” It spans about as wide as the entire United States.

MOM is India’s first deep space voyager to explore beyond the confines of her home planets influence and successfully arrived at the Red Planet after the “history creating” orbital insertion maneuver on Sept. 23/24, 2014 following a ten month journey from Earth.
MOM swoops around Mars in a highly elliptical orbit whose nearest point to the planet (periapsis) is at about 421 km and farthest point (apoapsis) at about 76,000 km, according to ISRO.

It takes MOM about 3.2 Earth days or 72 hours to orbit the Red Planet.

And with a communications blackout between Mars and Earth imminent as a result of natures solar conjunction, it’s the perfect time to catch up on all things Martian.

Solar conjunctions occur periodically between Mars and Earth about every 26 months, when the two planets line up basically in a straight line geometry with the sun in between as the two planets travel in their sun-centered orbits.

Since Mars will be located behind the Sun for most of June, communications with all the Terran spacecraft at the planet is diminished to nonexistent.

“MOM faces a communication outage during June 8-25,” according to The Hindu.

Normal science operations resume thereafter.

“Fuel on the spacecraft is not an issue,” ISRO Satellite Centre Director M. Annadurai told The Hindu.

The Martian Curiosity celebrates 1000 Sols on Mars!

Marking the occasion with utter glee, the car sized robot snapped a cool mosaic view (above) looking back to 1000 Sols of high impact exploration and discovery on the Red Planet, showing her wheel tracks leading back through valley dunes from the foothills of humongous Mount Sharp and across the alien surface floor and out to the distant rim of the Gale Crater landing site she descended to nearly three years ago in August 2012.

“A thousand thanks to the best team a rover could have. Celebrating 1,000 sols. Here’s to the Martian days ahead!” the robot tweeted.

But at 1K sols she’s not content to just bask in the Martian sunshine during the history making event. Rather, she is as always hard at work, reaching out with the high tech robotic arm and inspecting intriguing rock outcrops spread out all around her.

Check out Curiosity’s current workspace, looking back and hard at work in our new photo mosaics herein created by the imaging team of Marco Di Lorenzo and Ken Kremer. They are also featured at NBC News – here – and Alive Space Images (in Italian) – here and here.

The raw images for the look back mosaic were taken after she arrived at her current location on Martian Sol 997, or Earth’s Day May 28, 2015.

The Curiosity Mars Science Laboratory (MSL) rover officially celebrated 1000 Martian Sols on May 31, 2015 since she safely touched down on the crater floor on August 5, 2012 following the nail-biting and unprecedented sky crane maneuver that delivered her with pinpoint precision to a landing site nearby Mount Sharp.

“An MSL landmark day. We have reached 1000 sols on Mars. Looking back the remarkable thing is how few serious problems there have been,” says team member Professor John Bridges of the University of Leicester, England, in an update.

Exploring the sedimentary layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, form the primary destination and goal of her scientific expedition.

The six wheeled robot and her team of handlers back on Earth, are eeking out every last drop of science before she and all of Earth’s entire Martian invasion fleet enter solar conjunction, when Mars is behind the sun and little or no communications will be possible for most of the month of June. Activities will be limited per safety protocols.

“However, there is one issue even Curiosity can’t avoid – Conjunction. For much of June, Mars will be obscured from Earth by the Sun. Few science operations,” explains Bridges.

NASA’s long-lived Opportunity rover labors on the opposite side of Mars.

After a short drive Curiosity arrived at her current location at “Marias Pass” on Sol 997, where she will stay stationary during the conjunction period out of an abundance of caution.

“A short bump on Sol 997 put Curiosity in a great position to investigate a few different rock units in Marias Pass, using the instruments on the rover’s arm,” wrote MSL and USGS mission scientist Ken Herkenhoff in an update.

She also reached within an eyelash of 10.6 kilometers (6.6 mi) of total driving.

“The 2.5 m drive brings our total odometry to 10,599 m,” noted Herkenoff.

Along the way she discovered the chemical ingredient minerals necessary to support life, as well as low levels of some organic molecules and some traces of methane, and and ample evidence for lakes and streams of liquid water.

“Curiosity is now parked for the next few weeks. But we are parked in front of a beautiful outcrop that shows the contact between the underlying Pahrump unit and the overlying Stimson unit.”

Our arm photo mosaic herein shows the seven foot (2 m) long robotic arm and its APXS spectrometer deployed at the target called “Ronan”, which is part of the overlying Stimson outcrop unit.

The rover is also using the ChemCam, MastCam and MAHLI cameras and spectrometers and other instruments to characterize the outcrop and its texture and composition in detail.

The robotic arm will be stowed during the June conjunction period.

Curiosity arrived at the Pahrump Hills at the base of Mount Sharp back in September 2014. Since then she has conducted an intensive investigation of the rocks and a trio of drilling operations to elucidate how this area fits in context with Mount Sharp and the habitable region discovered on the crater floor at Yellowknife Bay back in the spring of 2013.

In recent weeks, Curiosity has been driving up hills with slopes of as much as 21 degrees, higher than ever before, on an exciting journey endeavoring to slowly ascend up to the lower layers of Mount Sharp.

The current Martian outcrop area under investigation is a place where two distinctive geologic types of bedrock meet and where pale rock meets darker overlying rock.

“Such contacts can reveal clues about how the environmental conditions that produced one type of rock were related to the conditions that produced the other,” says NASA.

“The rover science team wants to examine an outcrop that contains the contact between the pale rock unit the mission analyzed lower on Mount Sharp and a darker, bedded rock unit that the mission has not yet examined up close.”

The team is also scouting around for the presence of mineral veins, like those recently discovered at the “Garden City” outcrop, that formed in the past during periods of flowing liquid water that could be favorable for microbial life forms if they ever existed.

Because there’s a plethora of treacherous dunes, the team has had to monitor operations carefully and alter the route on occasion to maintain safe operations.

Curiosity 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.

As of today, Sol 1001, June 1, 2015, she has taken over 246,000 amazing images.

NASA’s Journey to Mars Ramps Up with InSight, Key Tests Pave Path to 2016 Lander Launch

As part of a series of deployment tests, the spacecraft was commanded to deploy its solar arrays in the clean room to test and verify the exact process that it will use on the surface of Mars.

NASA’s ‘Journey to Mars’ is ramping up significantly with ‘InSight’ – as the agency’s next Red Planet lander has now been assembled into its flight configuration and begun a comprehensive series of rigorous and critical environmental stress tests that will pave the path to launch in 2016 on a mission to unlock the riddles of the Martian core.

The countdown clock is ticking relentlessly and in less than nine months time, NASA’s InSight Mars lander is slated to blastoff in March 2016.

InSight, which stands for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport, is a stationary lander. It will join NASA’s surface science exploration fleet currently comprising of the Curiosity and Opportunity missions which by contrast are mobile rovers.

But before it will even be allowed to get to the launch pad, the Red Planet explorer must first prove its mettle and show that it can operate in and survive the harsh and unforgiving rigors of the space environment via a battery of prelaunch tests. That’s an absolute requirement in order for it to successfully carry out its unprecedented mission to investigate Mars deep interior structure.

InSight’s purpose is to elucidate the nature of the Martian core, measure heat flow and sense for “Marsquakes.” These completely new research findings will radically advance our understanding of the early history of all rocky planets, including Earth and could reveal how they formed and evolved.

“Today, our robotic scientific explorers are paving the way, making great progress on the journey to Mars,” said Jim Green, director of NASA’s Planetary Science Division at the agency’s headquarters in Washington, in a statement.

“Together, humans and robotics will pioneer Mars and the solar system.”

The launch window for InSight opens on March 4 and runs through March 30, 2016.

InSight will launch atop a United Launch Alliance (ULA) Atlas V rocket from Vandenberg Air Force Base, California.

InSight counts as NASA’s first ever interplanetary mission to launch from California.

The car sized probe will touch down near the Martian equator about six months later in the fall of 2016.

The prime contractor for InSight is Lockheed Martin Space Systems in Denver, Co and the engineering and technical team recently finished assembling the lander into its final configuration.

So now the time has begun to start the shakedown that literally involve “shaking and baking and zapping” the spacecraft to prove its ready and able to meet the March 2016 launch deadline.

During the next seven months of environmental testing at Lockheed’s Denver facility, “the lander will be exposed to extreme temperatures, vacuum conditions of nearly zero air pressure simulating interplanetary space, and a battery of other tests.”

“The assembly of InSight went very well and now it’s time to see how it performs,” said Stu Spath, InSight program manager at Lockheed Martin Space Systems, Denver, in a statement.

“The environmental testing regimen is designed to wring out any issues with the spacecraft so we can resolve them while it’s here on Earth. This phase takes nearly as long as assembly, but we want to make sure we deliver a vehicle to NASA that will perform as expected in extreme environments.”

The first test involves “a thermal vacuum test in the spacecraft’s “cruise” configuration, which will be used during its seven-month journey to Mars. In the cruise configuration, the lander is stowed inside an aeroshell capsule and the spacecraft’s cruise stage – for power, communications, course corrections and other functions on the way to Mars — is fastened to the capsule.”

After the vacuum test, InSight will be subjected to a series of tests simulating the vibrations of launch, separation and deployment shock, as well as checking for electronic interference between different parts of the spacecraft and compatibility testing.

Finally, a second thermal vacuum test will expose the probe “to the temperatures and atmospheric pressures it will experience as it operates on the Martian surface.”

The $425 million InSight mission is expected to operate for about two years on the Martian surface.

InSight is an international science mission and a near duplicate of NASA’s successful Phoenix Mars landing spacecraft, Bruce Banerdt, InSight Principal Investigator of NASA’s Jet Propulsion Laboratory (JPL), Pasadena, California, told Universe Today.

“InSight is essentially built from scratch, but nearly build-to-print from the Phoenix design,” Banerdt, of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena , Calif, told me. The team can keep costs down by re-using the blueprints pioneered by Phoenix instead of creating an entirely new spacecraft.

It is funded by NASA’s Discovery Program as well as several European national space agency’s and countries. Germany and France are providing InSight’s two main science instruments; HP3 and SEIS through the Deutsches Zentrum für Luft- und Raumfahrt. or German Aerospace Center (DLR) and the Centre National d’Etudes Spatiales (CNES).

“The seismometer (SEIS, stands for Seismic Experiment for Interior Structure) is from France (built by CNES and IPGP) and the heat flow probe (HP3, stands for Heat Flow and Physical Properties Probe) is from Germany (built by DLR),” Banerdt explained.

SEIS and HP3 are stationed on the lander deck. They will each be picked up and deployed by a robotic arm similar to that flown on Phoenix with some modifications.

Catch a ‘Conjunction Triple Play’ on February 20th as the Moon Meets Venus & Mars

The Moon passes Mars and Venus last month... this week's pass is much closer! (Photo by Author).

Fear not, the chill of late February. This Friday gives lovers of the sky a reason to brave the cold and look westward for a spectacular close triple conjunction of the planets Mars, Venus and the waxing crescent Moon.

This week’s New Moon is auspicious for several reasons. We discussed the vagaries of the Black Moon of February 2015 last week, and the lunacy surrounding the proliferation of the perigee supermoon. And Happy ‘Year of the Goat’ as reckoned on the Chinese luni-solar calendar, as this week’s New Moon marks the start of the Chinese New Year on February 19^th. Or do you say Ram or Sheep? Technical timing for the New Moon is on Wednesday, February 18^th at 23:47 UT/6:47 PM EST, marking the start of lunation 1140. The next New Moon on March 20^th sees the start of the first of two eclipse seasons for 2015, with a total solar eclipse for the high Arctic. More on that next month!

Feel like visiting a dwarf planet today? How about a comet or the planet Mars? Luckily for us, there are sentinels across the Solar System bringing us incredible images, allowing us to browse the photos and follow in the footsteps of these machines. And yes, there are even a few lucky humans taking pictures above Earth as well.

Below — not necessarily in any order — are some of the best space photos of 2014. You’ll catch glimpses of Pluto and Ceres (big destinations of 2015) and of course Comet 67P/Churyumov–Gerasimenko (for a mission that began close-up operations in 2014 and will continue next year.) Enjoy!

It seems a lot of the space stories of this year involve spacecraft making journeys: bouncing across a comet, or making their way to Mars. Private companies also figure prominently, both in terms of successes and prominent failures.

These are Universe Today’s picks for the top space stories of the year. Disagree? Think we forgot something? Let us know in the comments.

10. End of Venus Express

This month saw the end of Venus Express’ eight-year mission at the planet, which happened after the spacecraft made a daring plunge into part of the atmosphere to learn more about its properties. The spacecraft survived the aerobraking maneuvers, but ran out of fuel after a few engine burns to raise it higher. Soon it will plunge into the atmosphere for good. But it was a productive mission overall, with discoveries ranging from a slowing rotation to mysterious “glories”.

9. Continued discoveries by Curiosity and Opportunity

Methane? Organics? Water? Mars appears to have had these substances in abundance over its history. Continued work from the Curiosity rover — passing its second Earth year on Mars — found methane fluctuating in Gale Crater, and the first confirmed discovery of organics on the Martian surface. Opportunity is almost 11 years into its mission and battling memory problems, but the rover is still on the move (passing 41 kilometers) to an area that could be full of clay.

8. Siding Spring at Mars and the level of study of the comet by other missions at Mars

We had a rare opportunity to watch a comet make a grazing pass by Mars, not close enough to pose significant danger to spacecraft, but definitely close enough to affect its atmosphere! Siding Spring caught everyone’s attention throughout the year, and did not disappoint. The numerous spacecraft at the Red Planet caught glimpses, including from the surface and from orbit. It likely created a meteor shower and could alter the Martian atmosphere forever.

7. Kepler K2

The Kepler space telescope lost the second of its four pointing devices last year, requiring a major rethink for the veteran planet hunter. The solution was a new mission called K2 that uses the pressure of the Sun to maintain the spacecraft’s direction, although it has to flip every 83 days or so to a new location to avoid the star’s glare. It’s not as precise as before, but with the mission approved we now know for sure K2 can locate exoplanets. The first confirmed one is a super-Earth.

6. MAVEN at Mars

Where did the Martian atmosphere go? Why was it so thick in the past, allowing water to flow on the surface, and so thin right now? The prevailing theory is that the Sun’s pressure on the Martian atmosphere pushed lighter isotopes (such as that of hydrogen) away from the planet, leaving heavier isotopes behind. NASA is now investigating this in more detail with MAVEN (Mars Atmosphere and Volatile Evolution), which arrived at the planet this fall.

5. India’s MOM

India made history this year as only the third entity to successfully reach the Red Planet (after the United States and Europe). While updates from the Mars Orbiter Mission have been slow in recent weeks, we know for sure that it observed Siding Spring at Mars and it has been diligently taking pictures of the Red Planet, such as this one of the Solar System’s largest volcano and a huge canyon on Mars.

4. Accidents by Virgin and Orbital

In one sobering week in October, the dangers of space travel were again made clear after incidents affected Virgin Galactic and Orbital Sciences. Virgin lost a pilot and seriously injured another when something went seriously awry during a flight test. Investigators have so far determined that the re-entry system turned on prematurely, but more details are being determined. Orbital meanwhile suffered the catastrophic loss of one of its Antares rockets, perhaps due to Soviet-era-designed engines, but the company is looking at other ways to fulfill its NASA contractual obligations to send cargo to the International Space Station.

3. SpaceX rocket landing attempts

SpaceX is attempting a daunting technological feat, which is bringing back its rocket first stages for re-use. The company is hoping that this will cut down on the costs of launch in the long term, but this technological innovation will take some time. The Falcon 9 rocket stage that made it back to the ocean in July was deemed a success, although the force of the landing broke it apart. Next, SpaceX is trying to place its rocket on an ocean platform.

2. Orion flight

NASA’s spacecraft for deep space exploration (Orion) successfully finished its first major uncrewed test this month, when it rode into orbit, made a high-speed re-entry and successfully splashed down in the ocean. But it’s going to be a while before Orion flies again, likely in 2017 or even 2018. NASA hopes to put a crew on this spacecraft type in the 2020s, potentially for trips to the Moon, an asteroid or (more distantly) Mars.

1. Rosetta

New Rosetta mission findings do not exclude comets as a source of water in and on the Earth's crust but does indicate comets were a minor contribution. A four-image mosaic comprises images taken by Rosetta’s navigation camera on 7 December from a distance of 19.7 km from the centre of Comet 67P/Churyumov-Gerasimenko.

It’s been an exciting year for the Rosetta mission. First it woke up from a lengthy hibernation, then it discovered that Comet 67P/Churyumov-Gerasimenko looks a bit like a rubber duckie, and then it got up close and released the Philae lander. The soft touchdown did not go as planned, to say the least, as the spacecraft bounced for two hours and then came to rest in a spot without a lot of sunlight. While Philae hibernates and controllers hope it wakes up again in a few months, however, science results are already showing intriguing things. For example, water delivered to Earth likely came mostly from other sources than comets.
