NASA’s Opportunity mars rover now holds the off-Earth roving distance record after accruing 25 miles of driving. Given that the rover has been roaming the Red Planet for over a decade, that’s a travel speed of roughly 2.5 miles per year, and it’s one to be proud of.
“Opportunity has driven farther than any other wheeled vehicle on another world,” said Mars Exploration Rover Project Manager John Callas, from NASA’s Jet Propulsion Laboratory in a NASA press release. “This is so remarkable considering Opportunity was intended to drive about one kilometer and was never designed for distance. But what is really important is not how many miles the rover has racked up, but how much exploration and discovery we have accomplished over that distance.”
The previous record was held by the Soviet Union’s Lunokhod 2 rover, which landed on the moon in 1973. It drove about 24.2 miles in less than five months, according to calculations recently made using images from NASA’s Lunar Reconnaissance Orbiter.
“The Lunokhod missions still stand as two signature accomplishments of what I think of as the first golden age of planetary exploration, the 1960s and ’70s,” said Steve Squyres from Cornell University, and principal investigator for NASA’s twin Mars rovers. “We’re in a second golden age now, and what we’ve tried to do on Mars with Spirit and Opportunity has been very much inspired by the accomplishments of the Lunokhod team on the moon so many years ago. It has been a real honor to follow in their historical wheel tracks.”

A drive of 157 feet on July 27 put Opportunity’s odometer at 25.01 miles. The rover is currently headed southward along the western rim of Endeavour crater: a site that is continuing to yield evidence of ancient environments with less acidic water than those examined at Opportunity’s landing site.
If the rover can continue to operate for another 25.2 miles — the distance of a marathon — it will approach the next major investigation site: a valley, which scientists have dubbed “Marathon Valley.” Observations from spacecraft in orbit suggest that the valley is composed of a stack of layered sediments, offering a glimpse at the Red Planet’s changing geologic history.
Opportunity has continued to rove, gather scientific observations, and report back to Earth for over 40 times its designed lifespan. Now every additional mile reached will set the record for the longest off-Earth roving distance.
NASA’s decade old Opportunity rover has reached a long sought after region of aluminum-rich clay mineral outcrops at a new Endeavour crater ridge now “named ‘Pillinger Point’ after Colin Pillinger the Principal Investigator for the [British] Beagle 2 Mars lander”, Prof. Ray Arvidson, Deputy Principal Investigator for the rover, told Universe Today exclusively. See above the spectacular panoramic view from ‘Pillinger Point’ – where ancient water once flowed billions of year ago.
The Beagle 2 lander was built to search for signs of life on Mars.
The Mars Exploration Rover (MER) team named the noteworthy ridge in honor of Prof. Colin Pillinger – a British planetary scientist at the Open University in Milton Keynes, who passed away at the age of 70 on May 7, 2014.
‘Pillinger Point’ is a scientifically bountiful place possessing both clay mineral outcrops and mineral veins where “waters came up through the cracks”, Arvidson explained to me.
Since water is a prerequisite for life as we know it, this is a truly fitting tribute to name Opportunity’s current exploration site ‘Pillinger Point’ after Prof. Pillinger.
See our new photo mosaic above captured by Opportunity peering out from ‘Pillinger Point’ ridge on June 5, 2014 (Sol 3684) and showing a panoramic view around the eroded mountain ridge and into vast Endeavour crater.
The gigantic crater spans 14 miles (22 kilometers) in diameter.
See below our Opportunity 10 Year traverse map showing the location of Pillinger Point along the segmented rim of Endeavour crater.

Pillinger Point is situated south of Solander Point and Murray Ridge along the western rim of Endeavour in a region with caches of clay minerals indicative of an ancient Martian habitable zone.
For the past several months, the six wheeled robot has been trekking southwards from Solander towards the exposures of aluminum-rich clays – now named Pillinger Point- detected from orbit by the CRISM spectrometer aboard NASA’s powerful Martian ‘Spysat’ – the Mars Reconnaissance Orbiter (MRO) – while gathering context data at rock outcrops along the winding way.
“We are about 3/5 of the way along the outcrops that show an Al-OH [aluminum-hydroxl] montmorillonite [clay mineral] signature at 2.2 micrometers from CRISM along track oversampled data,” Arvidson told me.
“We have another ~160 meters to go before reaching a break in the outcrops and a broad valley.”
The rover mission scientists ultimate goal is travel even further south to ‘Cape Tribulation’ which holds a motherlode of the ‘phyllosilicate’ clay minerals based on extensive CRISM measurements accomplished earlier at Arvidson’s direction.
“The idea is to characterize the outcrops as we go and then once we reach the valley travel quickly to Cape Tribulation and the smectite valley, which is still ~2 km to the south of the present rover location,” Arvidson explained.
Mars Express and Beagle 2 were launched in 2003, the same year as NASA’s twin rovers Spirit and Opportunity, on their interplanetary voyages to help unlock the mysteries of Mars potential for supporting microbial life forms.
Pillinger was the driving force behind the British built Beagle 2 lander which flew to the Red Planet piggybacked on ESA’s Mars Express orbiter. Unfortunately Beagle 2 vanished without a trace after being deployed from the orbiter on Dec. 19, 2003 with an expected air bag assisted landing on Christmas Day, Dec. 25, 2003.
In an obituary by the BBC, Dr David Parker, the chief executive of the UK Space Agency, said that Prof. Pillinger had played a critical role in raising the profile of the British space programme and had inspired “young people to dream big dreams”.

During his distinguished career Pillinger also analyzed lunar rock samples from NASA’s Apollo moon landing missions and worked on ESA’s Rosetta mission.
“It’s important to note that Colin’s contribution to planetary science goes back to working on Moon samples from Apollo, as well as his work on meteorites,” Dr Parker told the BBC.
Today, June 16, marks Opportunity’s 3696th Sol or Martian Day roving Mars – compared to a warranty of just 90 Sols.
So far she has snapped over 193,400 amazing images on the first overland expedition across the Red Planet.
Her total odometry stands at over 24.51 miles (39.44 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

NASA’s incredibly long lived Opportunity rover has driven to the ridgeline of a Martian mountain and captured spectacular panoramic vistas peering down into the vast expanse of huge Endeavour crater and out along the jagged rim segments leading to her next target – which scientists believe holds minerals indicative of a habitable zone. See mosaic views above and below.
Since departing the world famous ‘Jelly Doughnut’ rock by the summit of ‘Solander Point’ in February, Opportunity has spent the past several months driving south and exploring intriguing rock outcrops on ‘Murray Ridge’ located along the eroded western rim of Endeavour Crater.
The renowned robot is now exploring a region of outcrops atop the rims ridge that’s a possible site harboring deposits of hydrated clay minerals, formed in the ancient past when Mars was warmer and wetter.
The ten year oldRed Planet rover first reached the rim of Endeavour Crater in August 2011. She has captured numerous sweeping gorgeous vistas during her first of its kind expedition on the surface of another planet by an alien probe from Earth.
Read my earlier story detailing the top 10 discoveries from twin sisters Spirit and Opportunity according to Deputy Principal Investigator Prof. Ray Arvidson – here.
The gigantic crater spans 14 miles (22 kilometers) in diameter.
So there is endless enthralling terrain to investigate – for at least another 10 years!
The floor of Endeavour crater is filled with dark sand, brighter dust, and, in the distance, dusty haze, says NASA.
This vista of the Endeavour Crater rim was acquired by NASA’s Mars Exploration Rover Opportunity’s panoramic camera on April 18, 2014, from the southern end of “Murray Ridge” on the western rim of the crater. In mid-May, the rover approached the dark outcrops on the flank of the hill at right. The high peak in the distance on the right is informally named “Cape Tribulation” and is about 1.2 miles (2 kilometers) to the south of Opportunity’s position when this view was recorded Credit: NASA/JPL-Caltech/Cornell Univ./Arizona State Univ.
Opportunity’s goal all the while has been to doggedly trek southwards towards exposures of aluminum-rich clays detected from orbit by NASA’s powerful Martian ‘Spysat’ – the Mars Reconnaissance Orbiter (MRO) – while gathering context data at rock outcrops at Murray Ridge along the winding way.
These aluminum-rich clay minerals, or phyllosilicates, likely formed billions of years ago in flowing liquid neutral water which is more conducive to life, compared to more acidic environments explored earlier in the mission, and is therefore potentially indicative of a Martian habitable zone and a scientific goldmine.
The science and engineering team has used the high resolution MRO spectral and imaging data to more efficiently direct Opportunity southwards along the Endeavour crater rim and towards the biggest caches of the clay minerals – which were detected at a mountainous rim segment called ‘Cape Tribulation’ and which is seen in the panoramic vistas.
Although Cape Tribulation still lies some 1.2 miles (2 kilometers) further south, the rover has just arrived at a region which the team believes shows the first signatures of the clay minerals.

“The rover is exploring the region of aluminum-hydroxyl clay minerals seen from orbit,” said NASA in a mission update.
The six wheeled robot will utilize her mast mounted cameras and arm mounted microscopic imager (MI) and APXS spectrometer to gather images and measurements to unlock the mysteries of Mars ability to support life – past or present.
“The more we explore Mars, the more interesting it becomes. These latest findings present yet another kind of gift that just happens to coincide with Opportunity’s 10th anniversary on Mars,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program.
“We’re finding more places where Mars reveals a warmer and wetter planet in its history. This gives us greater incentive to continue seeking evidence of past life on Mars.”

And Opportunity is now power-rich following a series of fortuitous wind cleaning events that substantially cleared the dust off the power generating solar wing arrays.
The solar array energy production has reached 761 watt-hours compared to about 900 watt-hours at landing in 2004 and only about 270 watt-hours just before Christmastime in December 2013.
“Solar panels [are] cleanest since about sol 1600 [September 2008],” says mission science team member Larry Crumpler.
More power means more work time and more bonus science studies and data return.
So the robot survived magnificently through her 6th harsh Martian winter with plenty of science rich targets planned ahead during the southern hemisphere Martian spring and summer.

“Tea, Earl Grey, hot.” Who doesn’t remember that famous command by Captain Picard’s of TV’s “Star Trek: The Next Generation”? While no one’s yet invented a replicator that can brew a cup of tea out of thin air, scientists have taken in step in that direction by creating an amazing replica of a Martian meteorite using a 3D printer.
Without the fuss and expense of a sample retrieving mission to Mars, NASA scientists now have a realistic, true to life facsimile of the ‘Block Island’ meteorite discovered by the Opportunity Rover in 2009. Block Island, an iron-nickel meteorite similar to those found at Meteor Crater in Arizona, is the largest meteorite found on the Red Planet.

Measuring about two feet (60 cm) across, it’s about the size of picnic cooler and weighs an estimated 1,000 pounds. The replica’s made of plastic – you could tote it around like a … picnic cooler.
Analysis of Block Island’s composition using the rover’s alpha particle X-ray spectrometer confirmed that it’s rich in iron and nickel. Scientists based the design of the plastic meteorite on detailed measurements and stereo images taken by Opportunity’s panoramic camera.

The rover made a 360-degree study of the meteorite five years ago taking measurements and many stereo images. But because Opportunity couldn’t see every square inch of the rock, the missing data created holes in the computer model, making it a poor candidate for 3D printing.
Last summer, scientists got around that problem by filling in the missing data and building small scale models of Block Island. To build the life-sized rock, they created depth meshes of the meteorite’s surface from six positions, then combined them into a three-dimensional digital model, according to researcher Kris Capraro of NASA’s Jet Propulsion Laboratory.

The printer built the meteorite from ABS plastic, the same material used in Lego bricks, with cord the width of the plastic line in your weed-whacker. One small problem remained before the replica could be executed – it was too big to fit in the printer’s building space. So researchers broke up the computer model of the meteorite into 11 sections. Printing took 305 hours and 36 minutes.

The sections were assembled and then painted to match the real rock. Said Capraro: “it’s the next best thing to bringing back real Martian rock samples back to Earth.”
Scientists hope someday to use 3D printing to not only replicate more Mars rocks but terrains across the solar system.
The Opportunity rover on Mars has gotten a 70% boost in power over the past few weeks. A good portion of that comes from the fact that its springtime in Mars’ southern hemisphere where Oppy now sits along the western rim of Endeavour Crater and so the Sun is now shining longer and higher in the sky. But also, several recent gusts of wind – or perhaps small dust devils – have cleaned much of the dust off the rover’s solar panels.
The rover team reported that between Sols 3605 and 3606 (March 15 and March 16, 2014), there was a dust cleaning event that resulted in about a 10% improvement in power production to 574 watt-hours, and then another cleaning event this week has put the power output to 615 watt-hours.
See a self-portrait that Opportunity took of its solar panels back in January to compare with the image above of how much cleaner the solar panels are now.

Of course, this is not the first time a wind cleaning event has dusted off the solar panels — in fact it has happened several times (see here, here, and here) which is one of the reasons for the longevity of the solar-powered rovers.
I love these self-images the rovers can take, and below is a great recent image the rover took of its own shadow, in the late-afternoon Sun. The image was taken by the rover’s rear hazard avoidance camera.

The image was taken looking eastward shortly before sunset on Sol 3,609 (March 20, 2014). The rover’s shadow falls across a slope called the McClure-Beverlin Escarpment on the western rim of Endeavour Crater, where Opportunity is investigating rock layers for evidence about ancient environments. The scene includes a glimpse into the distance across the 14-mile-wide (22-kilometer-wide) crater.

The team directing the epic trek of NASA’s Curiosity rover across the floor of Gale Crater has adopted new driving strategies and a new way forward in response to the unexpected wheel damage caused by driving over fields of rough edged Red Planet rocks in recent months.
This week, engineers directed dune buggy Curiosity to drive backwards for a lengthy distance over the Martian surface for the first time since landing.
The SUV sized vehicle apparently passed the reverse driving feasibility test with flying colors and is now well on the way to the exciting journey ahead aiming for the sedimentary layers at the base of towering Mount Sharp – the primary mission destination – which reaches 3.4 miles (5.5 km) into the Martian sky and possesses water altered minerals.
“We wanted to have backwards driving in our validated toolkit because there will be parts of our route that will be more challenging,” said Curiosity Project Manager Jim Erickson of NASA’s Jet Propulsion Laboratory, Pasadena, Calif, in a statement.
On Tuesday, Feb. 18, Curiosity not only drove in reverse, but the 329 feet (100.3 meters) distance covered marked her farthest one-day advance in over three months.
And she is also now roving over the much sought after smoother Martian terrain, as hoped, when the team decided to alter the traverse route based on high resolution imaging observations collected by the telescopic camera on NASA’s Mars Reconnaissance Orbiter (MRO) circling overhead.
The goal is to minimize wear and tear on the 20 inch diameter wheels.

Engineers were forced to devise new driving techniques and consider a new route forward after the aluminum wheels accumulated significant punctures and rips during the past few months of driving over fields strewn with sharp edged Martian rocks.
“We have changed our focus to look at the big picture for getting to the slopes of Mount Sharp, assessing different potential routes and different entry points to the destination area,” Erickson said.
“No route will be perfect; we need to figure out the best of the imperfect ones.”
But to reach the smooth terrain and the science rich targets located on the pathway ahead, the six wheeled rover first had to pass through a gateway known as the ‘Dingo Gap’ sand dune.

“Moonlight Valley” is the name of the breathtaking new locale beyond Dingo, Curiosity Principal Investigator John Grotzinger, of Caltech, told Universe Today.
Curiosity crossed through the 3 foot (1 meter) tall Dingo Gap sand dune with ease on Feb. 9 and roved on to targets in the “Moonlight Valley” and the region beyond.
“Moonlight Valley has got lots of veins cutting through it,” Grotzinger told me.
“We’re seeing recessive bedrock.”

Since passing through the Dingo Gap gateway, Curiosity has traveled another 937 feet (285.5 meters) for a total mission odometry of 3.24 miles (5.21 kilometers) since the nail biting landing on Aug. 6, 2012.
“After we got over the dune, we began driving in terrain that looks like what we expected based on the orbital data. There are fewer sharp rocks, many of them are loose, and in most places there’s a little bit of sand cushioning the vehicle,” Erickson said.

Curiosity’s near term goal is to reach her next science waypoint, named Kimberly (formerly called KMS-9) which lies about two-thirds of a mile (about 1.1 kilometers) ahead.
Kimberly is of interest to the science team because it sits at an the intersection of different rock layers.
The 1 ton robot may be directed to drill into another rock at Kimberly.
If approved, Kimberly would be her first since drilling operation since boring into Cumberland rock target last spring and since departing the Yellowknife Bay region in July 2013 where she discovered a habitable zone.

To date Curiosity’s odometer stands at 5.2 kilometers and she has taken over 118,000 images. The robot has about another 5 km to go to reach the foothills of Mount Sharp.

NASA’s renowned Mars rover Opportunity has been spied anew in a fabulous new photo captured just days ago by NASA’s ‘Spy in the Sky’ orbiter circling overhead the Red Planet. See Opportunity from above and below – from today’s location. See orbital view above – just released today.
The highly detailed image was freshly taken on Feb. 14 (Valentine’s Day 2014) by the telescopic High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO) as the decade old Opportunity was investigating the tasty alien terrain on ‘Murray Ridge’ – nearby the celebrated ‘jelly doughnut’ rock by the summit of Solander Point. See surface views below.
The fabulous orbital image shows not only rover Opportunity at her location today, but also the breathtaking landscape around the robots current location as well as some of the wheel tracks created by the Martian mountaineer as she climbed from the plains below up to near the peak of Solander Point.
The scene is narrowly focused on a spot barely one-quarter mile (400 meters) wide.
Murray Ridge and Solander Point lie at the western rim of a vast crater named Endeavour that spans some 22 kilometers (14 miles) in diameter.
Here is the corresponding Martian surface view snapped by Opportunity on Feb. 16, 2014 (looking back and down to Endeavour crater), while she’s being imaged from Mars orbit on Feb. 14, 2014:

Endeavour is an impact scar created billions of years ago. See our 10 Year Opportunity traverse map below.
And believe it or not, that infamous ‘jelly doughnut’ rock was actually the impetus for this new imaging campaign by NASA’s MRO Martian ‘Spysat.’
To help solve the mystery of the origin of the shiny 1.5 inches wide (4 centimeters) ‘jelly doughnut’ rock, dubbed ‘Pinnacle Island’, the science team decided to enlist the unparalleled capabilities of the HiRISE camera and imaging team in pursuit of answers.

‘Pinnacle Island’ had suddenly appeared out of nowhere in a set of before/after pictures taken by Opportunity’s cameras on Jan, 8, 2014 (Sol 3540), whereas that exact same spot had been vacant of debris in photos taken barely 4 days earlier. And the rover hadn’t budged a single millimeter.
So the HiRISE research team was called in to plan a new high resolution observation of the ‘Murray Ridge’ area and gather clues about the rocky riddle.
The purpose was to “check the remote possibility that a fresh impact by an object from space might have excavated a crater near Opportunity and thrown this rock to its new location”- now known as Pinnacle Island, said NASA in a statement.
Well, no fresh crater impacting site was found in the new image.
“We see no obvious signs of a very recent crater in our image, but a careful comparison to prior images might reveal subtle changes,” wrote HiRISE principal investigator Alfred McEwen in a description today.

In the meantime, as I reported here a few days ago the mystery was solved at last by the rover team after Opportunity drove a short distance away from the ‘jelly doughnut’ rock and snapped some ‘look back’ photographs to document the ‘mysterious scene’ for further scrutiny.
It turns out that the six wheeled Opportunity unknowingly ‘created’ the mystery herself when she drove over a larger rock, crushing and breaking it apart with the force from the wheels and her hefty 400 pound (185 kg) mass.
“Once we moved Opportunity a short distance, after inspecting Pinnacle Island, we could see directly uphill an overturned rock that has the same unusual appearance,” said Opportunity Deputy Principal Investigator Ray Arvidson of Washington University in St. Louis, in a NASA statement.
“Murray Ridge” and the Solander Point mountaintop are of great scientific interest because the region is riven with outcrops of minerals, including clay minerals, that likely formed in flowing liquid neutral water conducive to life – potentially a scientific goldmine.
Today, Feb 19, marks Opportunity’s 3582nd Sol or Martian Day roving Mars. She is healthy with plenty of power.
So far she has snapped over 188,800 amazing images on the first overland expedition across the Red Planet.
Her total odometry stands at over 24.07 miles (38.73 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

India’s maiden Mars explorer, the Mars Orbiter Mission or MOM, celebrated 100 days speeding through space this past week, racing outwards on its historic journey to the Red Planet.
After streaking through space for some ten and a half months, the 1,350 kilogram (2,980 pound) MOM probe will rendezvous with the Red Planet on September 24, 2014 – where she will study the atmosphere and sniff for signals of methane.
Feb. 12, 2014 marked ‘100 Days of MOM’ since the picture perfect blast off on Nov. 5, 2013 from India’s spaceport at the Satish Dhawan Space Centre, Sriharikota, atop the nations indigenous Polar Satellite Launch Vehicle (PSLV) which placed the probe into its initial Earth parking orbit.

A series of six subsequent orbit raising maneuvers ultimately culminated with the liquid fueled main engine firing on Dec. 1, 2013 for the Trans Mars Injection(TMI) maneuver that successfully placed MOM on a heliocentric elliptical trajectory to the Red Planet.
The TMI, affectionately dubbed ‘The mother of all slingshots’ finally provided the craft with sufficient thrust to achieve escape velocity and blast free of the Earth’s sphere of influence forever and begin her nearly yearlong momentous voyage to Mars.
The first of four in flight Trajectory Correction Maneuvers, TCM-1, was conducted by firing the 22 Newton Thrusters for a duration of 40.5 seconds on December 11, 2013. A trio of additional TCM firings are planned around April 2014, August 2014 and September 2014.

MOM was designed and developed by the Indian Space Research Organization’s (ISRO) at a cost of $69 Million and marks India’s inaugural foray into interplanetary flight.
During the first 100 days, the probe has traveled about 190 million kilometers and has a little less than 500 million kilometers and 205 days to go during her journey of some 680 million kilometers (400 million miles) overall.
A health check on February 6, 2014 confirmed that the 15 kg (33 lb) science payload comprising five Indian built instruments was turned “ON” and is operating well.
MOM is currently some 16 million km distant from Earth and one way radio signals take approximately 55 seconds.
“The round trip time is almost 2 minutes for a communication signal to go to MOM and come back, about the same time mom takes to make noodles!” ISRO noted humorously in a Facebook mission posting.
“Keep going MOM!”
MOM’s first Trajectory Correction Manoeuver in Baiju Raj’s imagination.
Following the ten month cruise through space the orbital insertion engine will fire for the do or die burn on September 24, 2014 placing MOM into an 377 km x 80,000 km elliptical orbit around Mars.
MOM is not alone in the frigid vacuum of space. She is joined by NASA’s MAVEN orbiter in pursuit of Mars.
MOM will reach Mars vicinity just two days after the arrival MAVEN on Sept. 22, 2014.
To date MAVEN has flown over 137 million miles (221 million km) of its total 442 million miles (712 million km) path to Mars.
If all continues to goes well, India will join an elite club of only four who have launched probes that successfully investigated the Red Planet from orbit or the surface – following the Soviet Union, the United States and the European Space Agency (ESA).
Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.
Together, MOM and MAVEN will fortify Earth’s invasion fleet at Mars. They join 3 current orbiters from NASA and ESA as well as NASA’s pair of sister surface rovers – Curiosity and Opportunity.
Although they were developed independently and have different suites of scientific instruments, the MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist told Universe Today.
“We have had some discussions with their science team, and there are some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.
“At the point where we [MAVEN and MOM] are both in orbit collecting data we do plan to collaborate and work together with the data jointly,” Jakosky said.
Stay tuned here for Ken’s continuing MOM, Opportunity, Curiosity, Chang’e-3, LADEE, MAVEN, Mars rover and more planetary and human spaceflight news.
The mystery of the world famous “Jelly Doughnut” rock on Mars has at last been solved by diligent mission scientists toiling away in dank research labs on Earth.
The “Jelly Doughnut” rock achieved worldwide fame, or better yet infamy, when it suddenly appeared out of nowhere in pictures taken by NASA’s renowned Red Planet rover Opportunity in January.
And the answer is – well it’s not heretofore undetected Martian beings or even rocks falling from the sky.
Rather its ‘Alien Space Invaders’ – in some sense at least.
And that ‘Alien Space Invader’ is from – Earth! And her name is – Opportunity!
Indeed sister rover Curiosity may have unwittingly pointed to the culprit and helped resolve the riddle when she snapped a brand new photo of Earth – home planet to Opportunity and Curiosity and all their makers! See the evidence for yourselves – lurking here!
It turns out that the six wheeled Opportunity unknowingly ‘created’ the mystery herself when she drove over a larger rock, crushing it with the force from the wheels and her 400 pound (185 kg) mass.
Fragments were sent hurtling across the summit of the north facing Solander Point mountain top, where she is currently climbing up ‘Murray Ridge’ along the western rim of a vast crater named Endeavour that spans some 22 kilometers (14 miles) in diameter. See traverse map below.
One piece unwittingly rolled downhill.
That rock fragment – now dubbed ‘Pinnacle Island’ – suddenly appeared in pictures taken by Opportunity’s cameras on Jan, 8, 2014 (Sol 3540).

And that exact same spot had been vacant of debris in photos taken barely 4 days earlier – during which time the rover didn’t move a single millimeter.
Pinnacle Island measures only about 1.5 inches wide (4 centimeters) with a noticeable white rim and red center – hence its jelly doughnut nickname.
The Martian riddle was finally resolved when Opportunity roved a tiny stretch and took some look back photographs to document the ‘mysterious scene’ for further scrutiny.
“Once we moved Opportunity a short distance, after inspecting Pinnacle Island, we could see directly uphill an overturned rock that has the same unusual appearance,” said Opportunity Deputy Principal Investigator Ray Arvidson of Washington University in St. Louis, in a NASA statement.
“We drove over it. We can see the track. That’s where Pinnacle Island came from.”
New pictures showed another fragment of the rock – dubbed ‘Stuart Island’ – eerily similar in appearance to the ‘Pinnacle Island’ doughnut.

To gather some up-close clues before driving away, the rover deployed its robotic arm to investigate ‘Pinnacle Island’ with her microscopic imager and APXS mineral mapping spectrometer.
The results revealed high levels of the elements manganese and sulfur “suggesting these water-soluble ingredients were concentrated in the rock by the action of water,” says NASA.
“This may have happened just beneath the surface relatively recently,” Arvidson noted, “or it may have happened deeper below ground longer ago and then, by serendipity, erosion stripped away material above it and made it accessible to our wheels.”

Continuing wheel damage from hoards of sharp edged Martian rocks are forcing engineers to seek a smoother pathway forward – potentially through a treacherous dune field – for NASA’s Curiosity rover on the jagged rock strewn road to Mount Sharp, her primary science destination.
Ever since rover engineers noticed holes and tears to the robots six aluminum wheels this past fall and winter 2013, the team has been photographing the wheels much more frequently and carefully assessing their condition. See our mosaics above and below.
Curiosity’s handlers are now considering diverting the SUV-sized robot to an alternate path crossing into a dune field and the valley beyond that entails traversing through much smoother Martian terrain to reach a highly desirable and nearby science destination called “KMS-9.”
Newly received images taken by the robot only on Friday, Jan. 31, reveal a very significant ragged looking puncture at least 2 to 3 inches (5 to 8 cm) in length and a inch or so (3 cm) wide that’s bent back to the inside of the left front wheel.

Unfortunately, the fields of rough Red Planet rocks have not been a blessing to the 1 ton behemoth.
See our new underbelly mosaic view of Curiosity’s holy wheels (above and below) snapped on Jan. 31, (Sol 529), that’s aimed at the interior and which vividly shows the extent of the injury to the 20 inch diameter wheel.

The rate of wheel damage has picked up dramatically as the driving pace accelerated across the rugged, rock filled Martian terrain over the past six months and put over 4.89 kilometers (3.04 mi.) on the odometer to date since the nailbiting August 2012 landing.
The mega robot is now standing at the edge of the dune field by the picturesque entrance known as the “Dingo Gap” after driving another 865 feet (264.7 meters) during January 2014.
You can see the increased damage resulting from the past months drive by comparing the new Sol 529 view with our underbelly mosaic from Sol 490 in December 2013.

However, the dune cutting across “Dingo Gap” measures about 3 feet (1 meter) in height.
Look at this 3-D “Dingo Gap” mosaic view from NASA and you can judge for yourself the choices the team faces.
Curiosity’s 3-D View Past Tall Dune at edge of ‘Dingo Gap’
This stereo mosaic of images from the Navigation Camera (Navcam) on Curiosity shows the terrain to the west from the rover’s position on Sol 528 (Jan. 30, 2014). The scene appears three dimensional when viewed through red-blue glasses with the red lens on the left. The view was taken just after Curiosity had arrived at the eastern edge of a location called “Dingo Gap.” A dune across the gap is about 3 feet (1 meter) high in the middle and tapered at south (left) and north (right) ends onto low scarps on either side of the gap. The rover team is evaluating possible driving routes on the other side before a decision whether the cross the gap. Credit: NASA/JPL-Caltech
So the team is evaluating whether that’s safe to bridge because they don’t want to get stuck in a hidden sand trap like the one that ultimately led to Spirit’s demise a few years back.
“The decision hasn’t been made yet, but it is prudent to go check,” said Jim Erickson of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., project manager for Curiosity, in a NASA statement.

“We’ll take a peek over the dune into the valley immediately to the west to see whether the terrain looks as good as the analysis of orbital images implies,” Erickson added, based on orbital images snapped by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO) circling overhead.
The team is also testing an array of different driving techniques to minimize the accumulation of wheel punctures, such as driving backwards or using only four of the six wheels to reduce the force of the wheels pushing against jagged rocks.
The “Dingo Gap” could offer a safer gateway to “KMS-9” along the journey of the rovers southwestwardly route to breathtaking foothills of Mount Sharp.

Dingo Gap lies between two low scarps and that is tapered off at both sides to the north and south.
KMS-9 is a potentially science rich target where the team hopes to conduct the first rock drilling operations since departing the Yellowknife Bay quadrant in July 2013.
The candidate drilling site lies only about half a mile (800 meters) away as the martian crow flies and features geology that’s appealing to the science team. But the roving routes under consideration are all much farther in actual distance.
“At KMS-9, we see three terrain types exposed and a relatively dust-free surface,” said science team collaborator Katie Stack of the California Institute of Technology, Pasadena.
Curiosity has already accomplished her primary goal of discovering a habitable zone on Mars that could support Martian microbes if they ever existed.
NASA’s rover Curiosity uncovered evidence that an ancient Martian lake had the right chemical ingredients, including clay minerals that could have sustained microbial life forms for long periods of time – and that these habitable conditions persisted on the Red Planet until a more recent epoch than previously thought.
As a result, the science team has shifted the missions focus to include the search for organic molecules – the building blocks of life as we know it – which may be preserved in the sedimentary rock layers of Mount Sharp.
“Really what we’re doing is turning the corner from a mission that is dedicated to the search for habitable environments to a mission that is now dedicated to the search for that subset of habitable environments which also preserves organic carbon,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology in Pasadena, said recently at the Dec. 2013 annual meeting of the American Geophysical Union (AGU).
Meanwhile, NASA’s Opportunity rover is exploring clay mineral outcrops by the summit of Solander Point on the opposite side of the Mars at the start of her 2nd Decade investigating the Red Planets mysteries.
