5 years after a heart throbbing Martian touchdown, Curiosity is climbing Vera Rubin Ridge in search of “aqueous minerals” and “clays” for clues to possible past life while capturing “truly breathtaking” vistas of humongous Mount Sharp – her primary destination – and the stark eroded rim of the Gale Crater landing zone from ever higher elevations, NASA scientists tell Universe Today in a new mission update.
You can catch a glimpse of what its like to see NASA’s Curiosity Mars rover simultaneously high overhead from orbit and trundling down low across the Red Planet’s rocky surface as she climbs the breathtaking terrain of Mount Sharp – as seen in new images from NASA we have stitched together into a mosaic view; showing the perspective views above.

Since it landed on August 6th, 2012, the Curiosity rover has spent a total of 1644 Sols (or 1689 Earth days) on Mars. And as of March 2017, it has traveled almost 16 km (~10 mi) across the planet and climbed almost a fifth of a kilometer (0.124 mi) in elevation. Spending that kind of […]
Tis a season of incredible wind driven activity on Mars like few before witnessed by our human emissaries ! Its summer on the Red Planet and the talented scientists directing NASA’s Curiosity rover have targeted the robots cameras so proficiently that they have efficiently spotted a multitude of ‘Dust Devils’ racing across the surface of Gale Crater.
Using data obtained from rock samples since 2011, one of Curiosity’s science teams has deduced that ancient Mars did not have enough carbon dioxide to maintain liquid water

Since it first landed on the surface of Mars on August 6th, 2012, the science team behind the Curiosity rover has conducted some crucial experiments. In the course of collecting rock samples, testing the air, and searching for organic molecules, the rover has revealed some very impressive things about Mars’ past.
After months of exploring the slopes around Mount Sharp, which sits in the ancient lake basin known as the Gale Crater, the rover team has been drilling into the formation see what’s hidden beneath. And with drill samples now obtained from Mount Sharp’s lower levels, the Curiosity team hopes to learn a great deal more about the planet’s ancient history.
For years, scientists have understood that Mount Sharp is essentially a giant mound of sedimentary deposits that were deposited by water billions of years ago. These sediment layers are believed to have been laid down over the course of 2 billion years, and most likely came into contact with the water that filled the crater 3.3. to 3.8 billion years ago.
As Ashwin Vasavada, the Deputy Project Scientist of the Curiosity mission at JPL, explained to Universe Today via email:
“Aeolis Mons, known informally as Mount Sharp, is the central mountain within Gale crater where Curiosity landed. It was chosen as Curiosity’s landing site because the mountain and the nearby plains have evidence for ancient liquid water in the form of channels and debris fans, as well as minerals that form when liquid water interacts with rock. Furthermore, the layers within lower Mount Sharp change in mineralogy in a way that indicates that they may record the drying out of Mars: lower and older layers indicate more water, while higher and younger layers indicate less.“
The drilling began late on Wednesday, Sept. 24th, when Curiosity’s hammering drill bore about 6.7 cm (2.6 inches) into Mount Sharp and collected a powdered-rock sample. Data and images of the drill sample were then received on the following morning (Thursday, Sept. 25th) at NASA’s Jet Propulsion Laboratory in Pasadena, California.
With drill samples now obtained from the lower level of Mount Sharp, Curiosity will soon deposit them into a scoop in the rover’s arm. While there, the rock powder will be examined to see if it is safe and of proper quality to be analyzed by Curiosity’s internal laboratory instruments, which will determine its chemical and mineralogical properties.
And once that analysis is complete, the Curiosity team hopes to make some more major discoveries of the region, the ultimate purpose of which is to determine if life could have existed in the Gale Crater during its warmer, wetter past. As Vasavada explained:
“Now that water-rich ancient environments have been discovered and studied on the plains and in the lowest layers of Mount Sharp, the team in drilling additional samples from progressively higher and younger layers to see how the ancient environment changed over time.
“The team also is searching for additional evidence of organic molecules that would help them understand whether the raw ingredients of life were present and how they degrade over time. The degradation is important to understand for the M2020 Mars rover mission that will search for signatures of ancient microbial life.”
Since September 11th, 2014, Curiosity has been exploring the slopes of Mount Sharp. As of Sept. 19th, 2016, the rover arrived at a area called “Pahrump Hills,” a basalt rock outcropping located in the lower region of Mount Sharp (known as the Murray Formation).
On Sept. 22nd, the rover completed mini-drill test to make sure the rock was suitable for drilling. This took place in an area known as “Confidence Hills”, which proved to be soft enough to obtain rock samples. This was the second mini-drill test since last month, the previous one having found that the rock was not stable enough for drilling.
Looking forward, the team plans to drill regularly as the rover climbs higher and higher along Mount Sharp, in the process accessing progressively younger layers of rock. In so doing, they will be able to create a comprehensive picture of how Mars evolved over time to become the dry and cold landscape it is today.
The team will also continue to use the rovers instruments to monitor the modern environment, including the weather and composition of the atmosphere to get a better picture of the planet’s meteorology today. Needless to say, this is not the last “taste” Curiosity will get of good ol’ Aeolis Mons!

Our beyond magnificent Curiosity rover has just finished her latest drilling campaign – at the target called “Quela” – into the simply unfathomable alien landscapes she is currently exploring at the “Murray Buttes” region of lower Mount Sharp. And it’s all in a Sols (or Martian Days’s) work for our intrepid Curiosity!
The “Murray Buttes” region is just chock full of the most stunning panoramic vistas that NASA’s Curiosity Mars Science Laboratory rover has come upon to date.
They fill the latest incredible chapter in her thus far four year long quest to trek many miles (km) from the Bradbury landing site along the floor of Gale Crater to reach the base region of humongous Mount Sharp.
And these adventures are just a prelude to the even more glorious vistas she’ll investigate from now on – as she climbs higher and higher on an expedition to thoroughly examine the mountains sedimentary layers and unravel billions and billions of years of Mars geologic and climatic history.
Drilling holes into Mars during the Red Planet trek and carefully analyzing the pulverized samples with the rovers pair of miniaturized chemistry laboratories (SAM and CheMin) is the route to the answer of how and why Mars changes for a warmer and wetter planet in the ancient past to the cold, dry and desolate world we see today.
The rock target named “Quella” is located at the base of one of the buttes dubbed “Murray Butte number 12,” according to that latest mission update from Prof. John Bridges, a Curiosity rover science team member from the University of Leicester, England.
It took two tries to get the drilling done due to a technical issue, but all went well in the end and it was well worth the effort at a place never before explored by an emissary from Earth.
“The drill (successful at second attempt) is at Quela.”
The full depth drilling was completed on Sol 1464, Sept. 18, 2016 as confirmed by imaging. And that immediately provided valuable insight into climate change on Mars.
“You can see how red and oxidised the tailings are, suggesting changing environmental conditions as we progress through the Mt. Sharp foothills,” Bridges explained in the mission update.
To give you the context of the of the Murray Buttes region and the drilling at Quela, the image processing team of Ken Kremer and Marco Di Lorenzo has begun stitching together wide angle mosaic landscape views and up close views of the drilling using raw images from a variety of the cameras at Curiosity’s disposal.
The next step after boring into Quela were to “sieve the new sample, dump the unsieved fraction, and drop some of the sieved sample into CheMin,” says Ken Herkenhoff, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.
“But first, ChemCam will acquire passive spectra of the Quela drill tailings and use its laser to measure the chemistry of the wall of the new drill hole and of bedrock targets “Camaxilo” and “Okakarara.” Right Mastcam images of these targets are also planned.”
“After sunset, MAHLI will use its LEDs to take images of the drill hole from various angles and of the CheMin inlet to confirm that the sample was successfully delivered. Finally, the APXS will be placed over the drill tailings for an overnight integration.”
The rover had approached the butte from the south side several sols earlier to get in place, plan for the drilling, take imagery to document stratigraphy and make compositional observations with the ChemCam laser instrument.
Sol after Sol the daily imagery transmitted back to eager researchers on Earth reveala spectacularly layered Martian rock formations in such exquisite detail that they look and feel just like America’s desert Southwest landscapes.
“These are the landforms that dominate the landscape at this point in the traverse – The Murray Buttes,” says Bridges.
What are the Murray Buttes?
“These are formed by a cap of hard aeolian rock that has been partially eroded back, overlying the Murray mudstone.”
Ascending and diligently exploring the sedimentary lower 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.
Three years ago, the team informally named the Murray Buttes site to honor Caltech planetary scientist Bruce Murray (1931-2013), a former director of NASA’s Jet Propulsion Laboratory, Pasadena, California. JPL manages the Curiosity mission for NASA.
As of today, Sol 1470, September 24, 2016, Curiosity has driven over 7.9 miles (12.7 kilometers) since its August 2012 landing inside Gale Crater, and taken over 355,000 amazing images.

The post Drilling at Unfathomable Alien Landscapes – All in a Sols (Day’s) Work for Curiosity appeared first on Universe Today.
KENNEDY SPACE CENTER VISITOR COMPLEX, FL- Think a Holodeck adventure on Star Trek guided by real life Apollo 11 moonwalker Buzz Aldrin and you’ll get a really good idea of what’s in store for you as you explore the surface of Mars like never before in the immersive new ‘Destination Mars’ interactive holographic exhibit opening to the public today, Monday, Sept.19.
The new exhibit was formally opened for business during a very special ribbon cutting ceremony featuring Buzz Aldrin as the star attraction – deftly maneuvering the huge ceremonial scissors during an in depth media preview and briefing on Sunday, Sept. 18, 2016, including Universe Today.
The fabulous new ‘Destination Mars’ limited engagement exhibit magically transports you to the surface of the Red Planet via Microsoft HoloLens technology.
It literally allows you to ‘Walk on Mars’ using real imagery taken by NASA’s Mars Curiosity rover and explore the alien terrain, just like real life scientists on a geology research expedition.
“Technology like HoloLens leads us once again toward exploration,” Aldrin said during the Sept. 18 media preview. “It’s my hope that experiences like “Destination: Mars” will continue to inspire us to explore.”
Destination Mars was jointly developed by NASA’s Jet Propulsion Laboratory – which manages the Curiosity rover mission for NASA, and Microsoft HoloLens.
Buzz was ably assisted at the grand ribbon cutting ceremony by Bob Cabana, former shuttle commander and current Kennedy Space Center Director, Therrin Protze, chief operating officer of the visitor complex, Kudo Tsunoda of Microsoft, and Jeff Norris of NASA’s Jet Propulsion Laboratory in Pasadena, California.
The experience is housed in a pop-up theater that only runs for the next three and a half months, until New Years Day, January 1, 2017.
Before entering the theater, you will be fitted with specially adjusted HoloLens headsets individually tailored to your eyes.
The entire ‘Destination Mars’ experience only lasts barely 8 minutes.
So, if you a lucky enough to get a ticket inside you’ll need to take advantage of every precious second to scan around from left and right and back, and top to bottom. Be sure to check out Mount Sharp and the rim of Gale Crater.
You’ll even be able to find a real drill hole that Curiosity bored into the Red Planet at Yellowknife Bay about six months after the nailbiting landing in August 2012.
During your experience you will be guided by Buzz and Curiosity rover driver Erisa Hines of JPL. They will lead you to areas of Mars where the science team has made many breakthrough discoveries such as that liquid water once flowed on the floor of Curiosity’s Gale Crater landing site.
The scenes come to life based on imagery combining the Mastcam color cameras and the black and white navcam cameras, Jeff Norris of NASA’s Jet Propulsion Laboratory in Pasadena, California, told Universe Today in an interview.
Among the surface features visited is Yellowknife Bay where Curiosity conducted the first interplanetary drilling and sampling on another planet in our Solar System. The sample were subsequently fed to and analyzed by the pair of miniaturized chemistry labs – SAM and CheMin – inside the rovers belly.
They also guide viewers to “a tantalizing glimpse of a future Martian colony.”
“The technology that accomplishes this is called “mixed reality,” where virtual elements are merged with the user’s actual environment, creating a world in which real and virtual objects can interact, “ according to a NASA description.
“The public experience developed out of a JPL-designed tool called OnSight. Using the HoloLens headset, scientists across the world can explore geographic features on Mars and even plan future routes for the Curiosity rover.”
Curiosity is currently exploring the spectacular looking buttes in the Murray Buttes region in lower Mount Sharp. Read my recent update here.
Be sure to pay attention or your discovery walk on Mars will be over before you know it. Personally, as a Mars lover and Mars mosaic maker I was thrilled by the 3 D reality and I was ready for more.
This limited availability, timed experience is available on a first-come, first-served basis. Reservations must be made the day of at the Destination: Mars reservation counter, says the KSC Visitor Complex.
You can get more information or book a visit to Kennedy Space Center Visitor Complex, by clicking on the website link:
Be sure to visit this spectacular holographic exhibit before it closes on New Year’s Day 2017 because it is only showing at KSCVC.
There are no plans to book it at other venues, Norris told me.
As of today, Sol 1465, September 19, 2016, Curiosity has driven over 7.9 miles (12.7 kilometers) since its August 2012 landing inside Gale Crater, and taken over 354,000 amazing images.
