NASA’s nearly decade old Opportunity Mars rover is sailing swiftly on a southerly course towards her first true mountain climbing destination – named “Solander Point” – in search of further evidence of habitable environments with the chemical ingredients necessary to sustain Martian life forms.

At Solander Point, researchers have already spotted deep stacks of ancient rocks transformed by flowing liquid water eons ago. It is located along the western rim of huge Endeavour Crater.

“Right now the rover team is discussing the best way to approach and drive up Solander,” Ray Arvidson told Universe Today. Arvidson is the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo.

Solander Point may harbor clay minerals in the rock stacks indicative of a past Martian habitable zone.

“One idea is to drive part way up Solander from the west side of the rim, turn left and then drive down the steeper north facing slopes with the stratographic sections,” Arvidson told me.

“That way we don’t have to drive up the relatively steeper slopes. The rover can drive up rocky surfaces inclined about 12 to 15 degrees.”

“We want to go through the stratographic sections on the north facing sections.”

The science team hopes that by scaling Solander, Opportunity will build on her recent historic discovery of a habitable environment at a rock called “Esperance” that possesses a cache of phyllosilicate clay minerals.

These aluminum rich clay minerals typically form in neutral, drinkable water that is not extremely acidic or basic and therefore could support a path to potential Martian microbes.

“Esperance ranks as one of my personal Top 5 discoveries of the mission,” said Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for NASA’s rover mission at a recent media briefing.

Using high resolution CRISM spectral data collected from Mars orbit, the rover was specifically directed to Esperance, Arvidson explained. The rock was found about a kilometer back on Matijevic Hill at ‘Cape York’, a rather low hilly segment of the western rim of giant Endeavour crater which spans 14 miles (22 km) across.

‘Solander Point’ offers roughly about a 10 times taller stack of geological layering compared to ‘Cape York.’ Both areas are raised segments of the western rim of Endeavour Crater.

The team is working now to obtain the same type of high resolution spectral evidence for phyllosilicate clay minerals at Solander as they had at Cape York to aid in targeting Opportunity to the most promising outcrops, Arvidson explained.

Opportunity is snapping ever more spectacular imagery of Solander Point and the eroded rim of Endeavour Crater as she approaches closer every passing Sol, or Martian Day. See our original photo mosaics herein by Marco Di Lorenzo and Ken Kremer.

The long lived robot arrived at the edge of Endeavour crater in mid-2011 and will spend her remaining life driving around the scientifically rich crater rim segments.

On June 21, 2013, Opportunity marked five Martian years on Mars since landing on Jan 24, 2004 with a mere 90 day (Sol) ‘warranty’.

This week Opportunity’s total driving distance exceeded 23 miles (37 kilometers).

The solar powered robot remains in excellent health and the life giving solar arrays are producing plenty of electrical power at the moment.

Solander Point also offers northerly tilled slopes that will maximize the power generation during Opportunity’s upcoming 6th Martian winter .

The rover handlers want Opportunity to reach Solander’s slopes by August, before winter’s onset.

As ot today (tosol) Opportunity has trekked about halfway from Cape York to Solander Point – tip to tip.

On the opposite side of Mars at Gale Crater, Opportunity’s younger sister rover Curiosity also discovered clay minerals and a habitable environment originating from a time when the Red Planet was far warmer and wetter billions of years ago.

NASA’s newly produced and absolutely spectacular panorama from the Curiosity mega rover offers armchair explorers back on Earth a mammoth 1.3 billion pixels worth of Mars in all its colorful glory.

And everyone can move back and forth around the interactive panorama and zoom in – with special embedded tools- to your hearts delight in exquisite detail at the ‘Rocknest’ site where the rover spent her first extended science stay in late 2012.

This extra special Rocknest panorama is the first NASA- produced view comprising more than a billion pixels from the surface of the Red Planet.

It offers a full 360 degree panoramic view around the rover encompassing breathtaking vistas of Mount Sharp and the eerie rim of Gale Crater, some 20 miles distant.

Mount Sharp rises 3.4 miles (5.5 km) high and is the target destination. The team hopes Curiosity will arrive at the base of Mount Sharp perhaps late this year or early in 2014.

The ‘Rocknest’ scene was assembled from nearly 900 raw images snapped by three different cameras among the 17 total that Curiosity uses as she trundles across the crater floor in search of the ingredients of life.

The panorama was created by Bob Deen of the Multi-Mission Image Processing Laboratory at NASA’s Jet Propulsion Laboratory, Pasadena, Calif, where the mission is managed on a daily basis.

“It gives a sense of place and really shows off the cameras’ capabilities,” said Deen in a statement. “You can see the context and also zoom in to see very fine details.”

“Rocknest” was a windblown ripple of sand dunes that Curiosity drove to after departing from the touchdown site at ‘Bradbury Landing’ and thoroughly investigated in October and November 2012.

It was at ‘Rocknest’ where the six wheeled rover famously deployed her robotic arm to scoop into the Martian dirt for the very first time and then delivered those first grains to the duo of analytical chemistry labs inside her belly that lie at the heart of Curiosity’s science mission.

Deen assembled the color product using 850 raw images from the 100 mm telephoto camera of Curiosity’s Mast Camera instrument, supplemented with 21 more from the Mastcam’s wider-angle 34 mm camera.

In order to take in the rover itself, the view also included 25 black-and-white raw images from the Navigation Camera on the Mast.

All the images were taken between Oct. 5 and Nov. 16, 2012 while the rover was stationary at Rocknest.

Because the images were captured over many days and at different times of day, the lighting and atmospheric clarity varies – especially in distant views to the crater rim.

Since landing on August 6, 2012, Curiosity has already accomplished her primary goal of finding a habitable zone at Gale Crater with an environment that could once of supported Martian microbial life – at the current worksite at ‘Yellowknife Bay.’

The 1 ton robot is equipped with 10 state-of-the-art science instruments with research capabilities that far surpass any prior landed mission and is in the middle of the 2-year primary mission to the Red Planet.

Meanwhile, Curiosity’s older sister rover Opportunity has also discovered clay minerals and a habitable zone on the opposite side of the Red Planet – details here.

Curiosity Gets Set for Epic Drive after Laser Blasting Mars Watery Secrets

Ten months after her breathtaking touchdown on the Red Planet, NASA’s Curiosity rover is nearly set to embark on an epic drive like no other in space history to the slopes of mysterious Mount Sharp – looming supreme inside Gale Crater and the primary mission objective.

But not before the robot completes a few last critical science tasks to more fully illuminate the potential for the origin of Martian microbes in the habitable zone discovered at the work-site of her first penetrations into Mars water altered surface.

The rover science team has chosen a trio of final targets to investigate around the shallow basin of Yellowknife Bay, that resembles a dried out lakebed, where Curiosity has toiled for the past six months, drilled twice into the mudstone outcrops at ‘John Klein’ and ‘Cumberland’ and repeatedly fired her powerful science laser.

Curiosity will revisit a pair of intriguing outcrops named ‘Point Lake’ and ‘Shaler’ that the rover briefly investigated before arriving at ‘John Klein’, said Joy Crisp of JPL, Curiosity’s deputy project scientist, at a media briefing.

“Shaler might be a river deposit. Point Lake might be volcanic or sedimentary. A closer look at them could give us better understanding of how the rocks we sampled with the drill fit into the history of how the environment changed.”

Curiosity will employ nearly all her science instruments to study the outcrops – except the drill.

“It’s highly unlikely to drill at ‘Point Lake’ and ‘Shaler’ because we want to get driving,” Crisp told Universe Today.

“We might drill somewhere along the way to Mount Sharp depending on whether we find something compelling.”

Researchers will also use the DAN (Dynamic Albedo of Neutrons) instrument to look for traces of mineral bound water – in the form of hydrogen – at the boundary between bedrock areas of mudstone and sandstone.

Thereafter, Curiosity’s handlers will command the 1 ton behemoth to begin the drive to the lower reaches of Mount Sharp which lies about 6 miles (10 kilometers) distant – as the Martian crow flies.

Mount Sharp rises about 3.4 miles (5.5 km) from the center of Gale Crater. It’s taller than Mount Ranier in Washington State.

Billions of years of Mars geologic history are preserved in the sedimentary layers of Mount Sharp – along with potential signatures of the chemical ingredients of life.

“The drive will start in a few weeks,” said Curiosity Project Manager Jim Erickson of NASA’s Jet Propulsion Laboratory, Pasadena, Calif. at the briefing.

But the team will be on the lookout for targets of opportunity along the way.

“We are on a mission of exploration. If we come across scientifically interesting areas, we are going to stop and examine them before continuing the journey,” Erikson added.

“If we pass something amazing and compelling we might turn around and drive back,” Crisp added.

It could take nearly a year to arrive at Mount Sharp. And Curiosity must pass through a potentially treacherous dune field to get there – see NASA JPL route map above.

“We are looking for the best path though,” said Erickson.

NASA chose Gale as the landing site specifically to dispatch Curiosity to investigate the sedimentary layers of Mount Sharp because it exhibited signatures of clay minerals that form in neutral water and that could possibly support the origin and evolution of simple Martian life forms, past or present.

“We have a real desire to get to Mount Sharp because there we see variations in the mineralogy as we go up from the base to higher levels and a change in the record of the environment,” said Crisp.

Analysis of the initial gray colored, powdery ‘John Klein’ sample by Curiosity’s pair of onboard chemistry labs – SAM & Chemin – revealed that this location on Mars was habitable in the past and possesses the key chemical ingredients – such as clay minerals – required to support microbial life forms- thereby successfully accomplishing the key science objective of the mission and making a historic discovery long before even arriving at destination Mount Sharp.

Besides the science measurements, researchers also learned lot about how to operate the complex drilling and sample delivery mechanisms much more efficiently for the second drilled rock sample.

The sieved and pulverized Cumberland sample was delivered in about a quarter of the time compared to the John Klein sample – accomplished at a deliberately measured and cautious pace.

Analysis of the “Cumberland” powder is currently in progress. The goal is to determine how it compares chemically and to confirm the results found at ‘John Klein.’

“No results from Cumberland are available yet,” said Crisp.

The robot used the powerful million watt ChemCam laser to blast into the Cumberland drill hole and gray tailings scattered on the surface to glean as much insight and measurements of the chemical composition and transformation by water as possible before departing.

Curiosity has just arrived at “Point Lake’. Stay tuned for my next Curiosity story.

Meanwhile, Curiosity’s older sister rover Opportunity has likewise discovered clay minerals and a habitable zone on the opposite side of the Red Planet – details here.

Opportunity Rover Discovers Martian Habitable Zone Favorable for Pre-biotic Chemistry

Opportunity captures a panoramic view of the road ahead to the raised rim of Solander Point (at left) which is some 0.8 mile (1.3 km) away. Arrival is targeted for August. It features a thick strata of ancient rocks which may harbor clay minerals indicative of a habitable zone and northerly tilted slopes to maximize power generation from the solar panels during upcoming 6th winter season at Endeavour crater rim.

On the cusp of the 10th anniversary since launching to the Red Planet, NASA’s long lived Opportunity rover has discovered a habitable zone on Mars that once coursed with ‘drinkable water’ and possesses the chemical ingredients necessary to support a path to potential Martian microbes.

At a rock called “Esperance”, Opportunity found a cache of phyllosilicate clay minerals that typically form in neutral, drinkable water that is not extremely acidic or basic.

The finding ranks as “One of my personal Top 5 discoveries of the mission,” said Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for NASA’s rover mission at a media briefing.

And despite her advancing age Opportunity remains healthy after surviving in excess of an incredible 3333 Sols, or days, trekking across the alien and ever harsh Martian crater plains.

Furthermore the intrepid robot just sat sail on a southerly course for a new destination called “Solander Point” where researches hope to find more even evidence of habitable environments since they already spotted deeper stakes of ancient rocks transformed by water eons ago. See our current photo mosaics showing Solander Point as Opportunity roves across the crater floor – above and below by Marco Di Lorenzo and Ken Kremer.

After weeks of trying, the rover deployed the robotic arm to drill at a sweet spot inside “Esperance” and collected convincing X-Ray spectroscopic data in the area she just investigated in May 2013 around the eroded rim of giant Endeavour Crater.

“Esperance is rich in clay minerals and shows powerful evidence of water alteration,” Squyres elaborated.

“This is the most powerful evidence we found for neutral pH water.”

“Clay minerals only tend to form at a more neutral pH. This is water you could drink,” Squyres gushed.

These finding represent the most favorable conditions for biology that Opportunity has yet seen in the rock histories it has encountered after nearly a decade roving the Red Planet.

“This is water that was much more favorable for things like pre-biotic chemistry – the kind of chemistry that could lead to the origin of life,” Squyres stated.

Esperance is unlike any rock previously investigated by Opportunity; rich in aluminum, which is strongly indicative of clay minerals, perhaps like montmorillonite.

Most rocks inspected to date by Opportunity were formed in an environment of highly acidic water that is extremely harsh to most life forms.

“If you look at all of the water-related discoveries that have been made by Opportunity, the vast majority of them point to water that was a very low pH – it was acid,” Squyres explained.

Esperance was found on ‘Cape York’, a hilly segment of the western rim of Endeavour crater which spans 14 miles (22 km) across. The robot arrived at the edge of Endeavour crater in mid-2011 and will spend her remaining life driving around the scientifically rich crater rim segments.

The pale rock in the upper center of this image, about the size of a human forearm, includes a target called "Esperance," which was inspected by NASA's Mars Exploration Rover Opportunity. Data from the rover's alpha particle X-ray spectrometer (APXS) indicate that Esperance's composition is higher in aluminum and silica, and lower in calcium and iron, than other rocks Opportunity has examined in more than nine years on Mars. Preliminary interpretation points to clay mineral content due to intensive alteration by water.

NASA’s new Curiosity rover also recently discovered clay minerals and a habitable environment at Gale Crater – on the other side of Mars – stemming from a time when Mars was warmer and wetter billions of years ago.

Over time Mars became the cold and dry place it is today. Scientists hope the rovers provide clues to Mars dramatic transformation.

The solar powered rover is now driving as quick as possible to reach the northerly tilled slopes of ‘Solander Point’ in August, before the onset of the next Martian winter.

‘Solander Point’ offers a much taller stack of geological layering than ‘Cape York.’ Both areas are raised segments of the western rim of Endeavour Crater.

“There’s a lot to explore there. In effect, it’s a whole new mission,” said Ray Arvidson, the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo.

Opportunity and her twin “Spirit” were launched to Mars on planned 90 day missions.

Both rovers have far exceeded everyone’s wildest expectations. Spirit endured more than 6 years inside Gusev Crater until succumbing to the bone chilling Martian winter in 2011.

Opportunity has lasted more than 37 times beyond the three month “warranty”.

“This is like your car not lasting 200,000 miles, or even a million miles. You’re talking about a car that lasts 2 million miles without an oil change,” Callas said. “At this point, how long Opportunity lasts is anyone’s guess.”

“Remember, the rover continues to operate in a very hostile environment, where we have extreme temperature changes every day, and the rover could have a catastrophic failure at anytime,” said John Callas, of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., project manager for the Mars Exploration Rover Project.

“So every day is a gift.”

Human Voyages to Mars Pose Higher Cancer Risks

NASA astronauts exploring Mars on future missions starting perhaps in the 2030’s will require protection from long term exposure to the cancer causing space radiation environment. Credit: NASA.

New measurements of the energetic space radiation environment present in interplanetary space taken by NASA’s Curiosity rover confirm what has long been suspected – that lengthy years long voyages by astronauts to deep space destinations like Mars will expose the crews to high levels of radiation that – left unchecked – would be harmful to their health and increase their chances of developing fatal cancers.

Although the data confirm what scientists had suspected, it’s equally important to state that the space radiation data are not ‘show stoppers” for human deep space voyages to the Red Planet and other destinations because there are a multitude of counter measures- like increased shielding and more powerful propulsion – that NASA and the world’s space agencies can and must implement to reduce and mitigate the dangerous health effects of radiation on human travelers.

The new radiation data was released at a NASA media briefing on May 30 and published in the journal Science on May 31.

Indeed the new measurements collected by Curiosity’s Radiation Assessment Detector (RAD) instrument during her 253-day, 560-million- kilometer journey enroute to the Red Planet in 2011 and 2012 will provide important insights to allow NASA to start designing systems for safely conducting future human missions to Mars.

“NASA wants to send astronauts to Mars in the 2030’s,” Chris Moore, NASA’s deputy director of Advanced Exploration Systems NASA HQ, said to reporters at the media briefing.

“The Human Spaceflight and Planetary Science Divisions at NASA are working together to get the data needed for human astronauts. RAD is perfect to collect the data for that,” said Moore.

The RAD data indicate that astronauts would be exposed to radiation levels that would exceed the career limit levels set by NASA during a more than year long voyage to Mars and back using current propulsion systems, said Eddie Semones, spaceflight radiation health officer at the Johnson Space Center.

This graph compares the radiation dose equivalent for several types of experiences, including a calculation for a trip from Earth to Mars based on measurements made by the Radiation Assessment Detector (RAD) instrument shielded inside NASA's Mars Science Laboratory spacecraft during the flight from Earth to Mars in 2011 and 2012. The data show that during a typical 6 month cruise to Mars the astronaut crews would be exposed to more than 3 times the typical 6 month exposure of astronauts aboard the ISS. The scale is logarithmic; each labeled value is 10 times greater than the next lowest one. The "dose equivalent" units are millisieverts.

NASA’s Humans to Mars planning follows initiatives outlined by President Obama.

“As this nation strives to reach an asteroid and Mars in our lifetimes, we’re working to solve every puzzle nature poses to keep astronauts safe so they can explore the unknown and return home,” said William Gerstenmaier, NASA’s associate administrator for human exploration and operations in Washington, in a statement.

The International Space Station already in low Earth orbit and the Orion crew capsule under development will serve as very useful platforms to conduct real life experiments on resolving the health risks posed by long term exposure to space radiation.

“We learn more about the human body’s ability to adapt to space every day aboard the International Space Station, said Gerstenmaier. “As we build the Orion spacecraft and Space Launch System rocket to carry and shelter us in deep space, we’ll continue to make the advances we need in life sciences to reduce risks for our explorers. Curiosity’s RAD instrument is giving us critical data we need so that we humans, like the rover, can dare mighty things to reach the Red Planet.”

RAD was the first instrument to collect radiation measurements during the cruise phase to the Red Planet. It is mounted on the top deck of the Curiosity rover.

“Although RAD’s objective is to characterize the radiation environment on the surface of Mars, it’s also good for the cruise phase,” Don Hassler, RAD Principal Investigator at the Southwest Research Institute (SWRI) told reporters.

“Since Orion and MSL are similar sized RAD is ideal for collecting the data.”

Hassler explained that RAD measures two types of radiation that pose health risks to astronauts. First, the steady stream of low dose galactic cosmic rays (GCRs), and second the short-term and unpredictable exposures to solar energetic particles (SEPs) arising from solar flares and coronal mass ejections (CME’s).

Radiation exposure is known to increase a person’s risk of suffering fatal cancer.

Exposure is measured in units of Sievert (Sv) or milliSievert (one one-thousandth Sv). Being exposed to a dose of 1 Sievert (Sv) over time results in a five percent increased risk of developing cancer.

NASA’s current regulations limit the potential for increased cancer risk to 3 percent for astronauts currently working on the ISS in low-Earth orbit.

RAD determined that the Curiosity rover was exposed to an average of 1.8 milliSieverts per day during the 8.5 month cruise to Mars, due mostly to Galactic Cosmic Rays, said Cary Zeitlin, SWRI Principal Scientist for MSL,at the briefing. “Solar particles only accounted for about 3 to 5 percent of that.”

During a typical 6 month cruise to Mars the astronaut crews would be exposed to 330 millisieverts. That is more than 3 times the typical 6 month exposure of astronauts aboard the ISS which amounts to about 100 millisieverts. See graphic above.

“The 360 day interplanetary round trip exposure would be 660 millisieverts based on chemical propulsion methods,” Zeitlin told Universe Today. “A 500 day mission would increase that to 900 millisieverts.”

By comparison, the average annual exposure for a typical person in the US from all radiation sources is less than 10 millisieverts.

The Earth’s magnetic field provides partial radiation shielding for the ISS astronauts living in low-Earth orbit.

“In terms of accumulated dose, it’s like getting a whole-body CT scan once every five or six days,” says Zeitlin.

And that round trip dose of 660 millisieverts doesn’t even include the astronauts surface stay on Mars – which would significantly raise the total exposure count. But luckily for the crew the surface radiation is less.

“The radiation environment on the surface of Mars is about half that in deep space since its modified by the atmosphere,” Hassler told Universe Today. “We will publish the surface data in a few months.”

NASA will need to decide whether to reassess the acceptable career limits for astronauts exposure to radiation from galactic cosmic rays and solar particle events during long duration deep space journeys.

Boeing Commercial Space Taxi and Atlas V Launcher Move Closer to Blastoff

The next time that American astronauts launch to space from American soil it will surely be aboard one of the new commercially built “space taxis” currently under development by a trio of American aerospace firms – Boeing, SpaceX and Sierra Nevada Corp – enabled by seed money from NASA’s Commercial Crew Program (CCP).

Boeing has moved considerably closer towards regaining America’s lost capability to launch humans to space when the firm’s privately built CST-100 crew capsule achieved two key new milestones on the path to blastoff from Florida’s Space Coast.

The CST-100 capsule is designed to carry a crew of up to 7 astronauts on missions to low-Earth orbit (LEO) and the International Space Station (ISS) around the middle of this decade.

Boeing’s crew transporter will fly to space atop the venerable Atlas V rocket built by United Launch Alliance (ULA) from Launch Complex 41 on Cape Canaveral Air Force Station in Florida.

The Boeing and ULA teams recently completed the first wind tunnel tests of a 7 percent scale model of the integrated capsule and Atlas V rocket (photo above) as well as thrust tests of the modified Centaur upper stage.

The work is being done under the auspices of NASA’s Commercial Crew Integrated Capability (CCiCap) initiative, intended to make commercial human spaceflight services available for both US government and commercial customers, such as the proposed Bigelow Aerospace mini space station.

Since its maiden liftoff in 2002, the ULA Atlas V rocket has flawlessly launched numerous multi-billion dollar NASA planetary science missions like the Curiosity Mars rover, Juno Jupiter orbiter and New Horizons mission to Pluto as well as a plethora of top secret Air Force spy satellites.

But the two stage Atlas V has never before been used to launch humans to space – therefore necessitating rigorous testing and upgrades to qualify the entire vehicle and both stages to meet stringent human rating requirements.

“The Centaur has a long and storied past of launching the agency’s most successful spacecraft to other worlds,” said Ed Mango, NASA’s CCP manager at the agency’s Kennedy Space Center in Florida. “Because it has never been used for human spaceflight before, these tests are critical to ensuring a smooth and safe performance for the crew members who will be riding atop the human-rated Atlas V.”

The combined scale model CST-100 capsule and complete Atlas V rocket were evaluated for two months of testing this spring inside an 11- foot diameter transonic wind tunnel at NASA’s Ames Research Center in Moffett Field, Calif.

“The CST-100 and Atlas V, connected with the launch vehicle adaptor, performed exactly as expected and confirmed our expectations of how they will perform together in flight,” said John Mulholland, Boeing vice president and program manager for Commercial Programs.

Testing of the Centaur stage centered on characterizing the flow of liquid oxygen from the oxygen tank through the liquid oxygen-feed duct line into the pair of RL-10 engines where the propellant is mixed with liquid hydrogen and burned to create thrust to propel the CST-100 into orbit.

Boeing is aiming for an initial three day manned orbital test flight of the CST-100 during 2016, says Mulholland.

But that date is dependent on funding from NASA and could easily be delayed by the ongoing sequester which has slashed NASA’s and all Federal budgets.

Chris Ferguson, the commander of the final shuttle flight (STS-135) by Atlantis, is leading Boeing’s flight test effort.

Boeing has leased one of NASA’s Orbiter Processing Facility hangers (OPF-3) at the Kennedy Space Center (KSC) for the manufacturing and assembly of its CST-100 spacecraft.

Mulholland told me previously that Boeing will ‘cut metal’ soon. “Our first piece of flight design hardware will be delivered to KSC and OPF-3 around mid 2013.”

NASA’s CCP program is fostering the development of the CST-100 as well as the SpaceX Dragon and Sierra Nevada Dream Chaser to replace the crew capability of NASA’s space shuttle orbiters.

The Atlas V will also serve as the launcher for the Sierra Nevada Dream Chaser space taxi.

Since the forced retirement of NASA’s shuttle fleet in 2011, US and partner astronauts have been 100% reliant on the Russians to hitch a ride to the ISS aboard the Soyuz capsules – at a price tag exceeding $60 Million per seat.

Simultaneously on a parallel track NASA is developing the Orion crew capsule and SLS heavy lift booster to send humans to the Moon and deep space destinations including Asteroids and Mars.

Curiosity Drills 2nd Hole into Ancient Mars Rocks Searching for the Ingredients of Life

NASA’s Curiosity rover has just successfully bored inside ancient rocks on Mars for only the 2nd time since her nail biting landing in August 2012 inside Gale Crater as she searches for the ingredients of life.

On Sunday, May 20, the rover drilled about 2.6 inches (6.6 centimeters) deep into a target named “Cumberland” to collect powdery samples from the rock’s interior that hold the secrets to the history of water and habitability on the Red Planet.

“Cumberland” is literally just a stone’s throw away from the first drill target named “John Klein” where Curiosity bored the historic first drill hole on an alien world three months ago in February.

NASA's Mars rover Curiosity drilled into this rock target, "Cumberland," during the 279th Martian day, or sol, of the rover's work on Mars (May 19, 2013) and collected a powdered sample of material from the rock's interior. Analysis of the Cumberland sample using laboratory instruments inside Curiosity will check results from "John Klein," the first rock on Mars from which a sample was ever collected and analyzed. The two rocks have similar appearance and lie about nine feet (2.75 meters) apart.

Analysis of the gray colored, powdery “John Klein” sample by Curiosity’s pair of onboard chemistry labs – SAM & Chemin – revealed that this location on Mars was habitable in the past and possesses the key chemical ingredients required to support microbial life forms – thereby successfully accomplishing the key science objective of the mission and making a historic discovery.

The Cumberland powder will be fed into SAM and Chemin shortly through a trio of inlet ports on the rover deck.

‘Cumberland’ lies about nine feet (2.75 meters) west of ‘John Klein’. Both targets are inside the shallow depression named ‘Yellowknife Bay’ where Curiosity has been exploring since late 2012.

The six wheeled NASA robot arrived at Cumberland just last week on May 14 (Sol 274) after a pair of short drives.

The science team directed Curiosity to drill into ‘Cumberland’ to determine if it possesses the same ingredients found at “John Klein” and whether the habitable environment here is widespread and how long it existed in Mars’ history.

“We’ll drill another hole [at Cumberland] to confirm what we found in the John Klein hole,” said John Grotzinger to Universe Today. Grotzinger, of the California Institute of Technology in Pasadena, Calif., leads NASA’s Curiosity Mars Science Laboratory mission.

“The favorable conditions included the key elemental ingredients for life, an energy gradient that could be exploited by microbes, and water that was not harshly acidic or briny,” NASA said in a statement.

‘Cumberland’ and ‘John Klein’ are patches of flat-lying bedrock shot through with pale colored hydrated mineral veins composed of calcium sulfate and featuring a bumpy surface texture inside the ‘Yellowknife Bay’ basin that resembles a dried out lake bed.

“We have found a habitable environment [at John Klein] which is so benign and supportive of life that probably if this water was around, and you had been on the planet, you would have been able to drink it,” said Grotzinger.

Curiosity will remain at Cumberland for several weeks to fully characterize the area and then continue exploring several additional outcrops in and around Yellowknife Bay.

“After that we’re likely to begin the trek to Mt. Sharp, though we’ll stop quickly to look at a few outcrops that we passed by on the way into Yellowknife Bay,” Grotzinger told me.

One stop is likely to include the ‘Shaler’ outcrop of cross-bedding that was briefly inspected on the way in.

Thereafter the 1 ton rover will resume her epic trek to the lower reaches of mysterious Mount Sharp, the 3.5 mile (5.5 km) high layered mountain that dominates her landing site and is the ultimate driving goal inside Gale Crater.

Drill, Baby, Drill! – How Does Curiosity ‘Do It’

Video Caption: This JPL video shows the complicated choreography to get drill samples to Curiosity’s instruments as she prepares for 2nd drilling at “Cumberland.” See where “Cumberland” is located in our panoramic photo mosaic below.

It’s time at last for “Drill, Baby, Drill!” – Martian Style.

Ever wonder how Curiosity “Does It”

Well, check out this enlightening and cool new NASA video for an exquisitely detailed demonstration of just how Curiosity shakes, rattles and rolls on the Red Planet and swallows that mysterious Martian powder.

“Shake, shake, shake… shake that sample. See how I move drilled rock to analytical instruments,” tweeted Curiosity to millions of fans.

Get set to witness Martian gyrations like you’ve never seen before.

After a pair of short but swift moves this past week, NASA’s Curiosity rover is finally in position to bore into the Red Planet’s alien surface for the second time – at a target called “Cumberland.”

See where “Cumberland” is located in our panoramic photo mosaic below.

“Two short drives & 3.8 meters later, I’m zeroing in on my second Mars drilling target,” tweeted Curiosity.

These were Curiosity’s first drives since arriving at the “John Klein” outcrop in mid- January 2013 where she carried out the historic first ever interplanetary drilling by a robot on another world.

For the past few days the robot has snapped a series of close up images of “Cumberland” with the high resolution MAHLI camera on the “hand” of the dextrous robotic arm.

And now that Curiosity has switched to the B-side computer, the rover has switched over to an back up set of never before used cameras on the mast head, which appear to be functioning perfectly.

“Curiosity is now using the new pair of navigation cameras associated with the B-side computer,” said Curiosity science team member Kimberly Lichtenberg to Universe Today.

The rover also evaluated the potential drill site with the ChemCAM and APXS instruments to confirm whether ‘Cumberland’ is indeed a worthy target for the time consuming process to collect the drill tailings for delivery to the duo of miniaturized chemistry labs named SAM and Chemin inside her belly

As outlined in the video, the robot engages in an incredibly complex procedure to collect the drill bit tailings and then move and pulverize them through the chambers of the CHIMRA sample system on the tool turret for processing, filtering and delivery for in situ analysis that could take weeks to complete.

This patch of bedrock, called "Cumberland," has been selected as the second target for drilling by NASA's Mars rover Curiosity. The rover has the capability to collect powdered material from inside the target rock and analyze that powder with laboratory instruments.

The state-of-the-art SAM and Chemin chemistry labs test aspirin sized quantities of the carefully sieved powder for the presence of organic molecules – the building blocks of life – and determine the inorganic chemical composition.

The science team wants to know how ‘Cumberland’ stacks up compared to ‘John Klein’, inside the shallow depression named ‘Yellowknife Bay’ where Curiosity has been exploring since late 2012.

“We’ll drill another hole to confirm what we found in the John Klein hole,” said John Grotzinger to Universe Today. Grotzinger, of the California Institute of Technology in Pasadena, Calif., leads NASA’s Curiosity Mars Science Laboratory mission.

‘Cumberland’ and ‘John Klein’ are patches of flat-lying bedrock shot through with pale colored hydrated mineral veins composed of calcium sulfate hydrated and a bumpy surface texture at her current location inside the ‘Yellowknife Bay’ basin that resembles a dried out lake bed.

“The bumpiness is due to erosion-resistant nodules within the rock, which have been identified as concretions resulting from the action of mineral-laden water,” according to NASA.

At Yellowknife Bay, Curiosity found evidence for an ancient habitable environment that could possibly have supported simple Martian microbial life forms eons ago when the Red Planet was warmer and wetter.

Analysis of the gray colored rocky Martian powder at ‘John Klein’ revealed that the fine-grained, sedimentary mudstone rock possesses significant amounts of phyllosilicate clay minerals; indicating the flow of nearly neutral liquid water and a habitat friendly to the possible origin of microbes.

Curiosity is expected to drill and swallow the ‘Cumberland’ powder at any moment if all goes well, a team member told Universe Today.

Curiosity Reaches Out with Martian Handshake and Contemplates New Drilling at Habitable Site

NASA’s Curiosity rover reaches out in ‘handshake’ like gesture to welcome the end of solar conjunction and resumption of contact with Earth. This mosaic of images was snapped by Curiosity on Sol 262 (May 2, 2013) and shows her flexing the robotic arm with dramatic scenery of Mount Sharp in the background.

NASA’s Curiosity rover has reached out in a Martian ‘handshake’ like gesture welcoming the end of solar conjunction that marks the resumption of contact with her handlers back on Earth – evidenced in a new photo mosaic of images captured as the robot and her human handlers contemplate a short traverse to a 2nd drilling target in the next few days.

“We’ll move a small bit and then drill another hole,” said John Grotzinger to Universe Today. Grotzinger, of the California Institute of Technology in Pasadena, Calif., leads NASA’s Curiosity Mars Science Laboratory mission.

The rover science team and Grotzinger have selected that 2nd drill location and are itching to send the rover on her way to the bumpy spot called “Cumberland.”

Cumberland lies about nine feet (2.75 meters) west of the “John Klein’ outcrop where Curiosity conducted humanity’s first ever interplanetary drilling on the alien Martian surface in February 2013.

“We’ll confirm what we found in the John Klein hole,” Grotzinger told me.

Curiosity discovered a habitable zone at the John Klein drill site.

After pulverizing and carefully sifting the John Klein drill tailings, a powered, aspirin sized portion of the gray rock was fed into a trio of inlet ports atop the rovers deck and analyzed by Curiosity’s duo of miniaturized chemistry labs named SAM and Chemin inside her belly to check for the presence of organic molecules and determine the inorganic chemical composition.

‘Cumberland’ and ‘John Klein’ are patches of flat-lying bedrock shot through with pale colored calcium sulfate hydrated mineral veins and a bumpy surface texture at her current location inside the ‘Yellowknife Bay’ basin.

“The bumpiness is due to erosion-resistant nodules within the rock, which have been identified as concretions resulting from the action of mineral-laden water,” NASA said in a statement.

Curiosity snapped high resolution color images of Cumberland on Sol 192 (Feb. 19, 2013) as part of the ongoing data collection campaign to put Yellowknife Bay into scientific context and search for future drill targets.

The John Klein bore hole (drilled on Feb 8, 2013, Sol 182) is visible in our new photo mosaic above created by myself and my imaging partner Marco Di Lorenzo. It was stitched from a ‘Martian baker’s dozen’ of raw images captured on May 2 (Sol 262). and shows the hand-like tool turret positioned above the first pair of drill holes.

Our new Sol 262 mosaic illustrates that Curiosity is again fully functional and flexing the miracle arm following a relaxing month long period of ‘Spring Break’ when there was no two- way communication with Earth during April’s solar conjunction.

The Sol 262 photo mosaic was originally featured at NBC News by Cosmic Log science editor Alan Boyle who likened it to a future Martian handshake in this cleverly titled story; “Curiosity’s ‘hand’ outstretched on Mars: Will humans ever shake it?”

See below our Sol 169 panoramic context view of Curiosity inside Yellowknife Bay collecting spectroscopic science measurements at the John Klein outcrop.

Curiosity found that the fine-grained, sedimentary mudstone rock at the John Klein worksite inside the shallow depression known as Yellowknife Bay possesses significant amounts of phyllosilicate clay minerals; indicating the flow of nearly neutral liquid water and a habitat friendly to the possible origin of simple Martian microbial life forms eons ago.

Grotzinger also explained to Universe Today that Curiosity will soon to more capable than ever before.

“We’ll spend the next few sols transitioning over to new flight software that gives the rover additional capabilities’” said Grotzinger.

“Then we’ll spend some time testing out the science instruments on the B-side rover compute element – that we booted to before conjunction.”

Curiosity will spend a month or more at the Cumberland site to collect and completely analyze the drill tailings.

Then she’ll resume her epic trek to mysterious Mount Sharp, the 3.5 mile (5 km) high mountain that dominates her landing site and is her ultimate driving inside Gale Crater according to Grotzinger.

“After that [Cumberland] we’re likely to begin the trek to Mt. Sharp, though we’ll stop quickly to look at a few outcrops that we passed by on the way into Yellowknife Bay,” Grotzinger explained to Universe Today.

The Shaler outcrop passed by on the path into Yellowknife Bay is high on the list of stops during the year long journey to Mount Sharp, says Grotzinger. Read more details about Shaler in a new BBC story by Jonathan Amos – here – featuring our Shaler outcrop mosaic.

This map shows the location of "Cumberland," the second rock-drilling target for NASA's Mars rover Curiosity, in relation to the rover's first drilling target, "John Klein," within the southwestern lobe of a shallow depression called "Yellowknife Bay." Cumberland, like John Klein, is a patch of flat-lying bedrock with pale veins and bumpy surface texture. The bumpiness is due to erosion-resistant nodules within the rock, which have been identified as concretions resulting from the action of mineral-laden water.

Do you want to go to Mars?

Well here’s your chance to get connected for a double barreled dose of Red Planet adventure courtesy of MAVEN – NASA’s next ‘Mission to Mars’ which is due to liftoff this November from the Florida Space Coast.

For a limited time only, NASA is offering the general public two cool ways to get involved and ‘Go to Mars’ aboard a DVD flying on the solar winged MAVEN (Mars Atmosphere and Volatile Evolution) orbiter.

You can send your name and a short poetic message to Mars via the ‘Going to Mars’ campaign being managed by the University of Colorado at Boulder’s Laboratory for Atmospheric and Space Physics (CU/LASP).

“Anybody on planet Earth is welcome to participate!” says NASA.

“The Going to Mars campaign offers people worldwide a way to make a personal connection to space, space exploration, and science in general, and share in our excitement about the MAVEN mission,” said Stephanie Renfrow, lead for the MAVEN Education and Public Outreach program at CU/LASP.

Signing up to send your name is easy. Simply click on the MAVEN mission website – here.

Everyone who submits their name will be included on a DVD that will be attached to the winged orbiter. And you can print out a beautiful certificate of participation emblazoned with your name!

Over 1 million folks signed up to send their names to Mars with NASA’s Curiosity rover. So they are all riding along as Curiosity continues making ground breaking science discoveries and already found habitats that could support potential Martian microbes.

Writing the haiku poem will require thought, inspiration and creativity and involves a public contest – because only 3 poems will be selected and sent to Mars. The public will vote for the three winning entries.

Haiku’s are three line poems. The rules state that “the first and last lines must have exactly five syllables each and the middle line must have exactly seven syllables. All messages must be original and not plagiarized in any way.”

The complete contest rules are found at the mission website – here:

This is a simple way for kids and adults alike to participate in humanity’s exploration of the Red Planet. And it’s also a great STEM activity for educators and school kids of all ages before this year’s school season comes to a close.

“This new campaign is a great opportunity to reach the next generation of explorers and excite them about science, technology, engineering and math,” said Bruce Jakosky, MAVEN principal investigator from CU/LASP. “I look forward to sharing our science with the worldwide community as MAVEN begins to piece together what happened to the Red Planet’s atmosphere.”

MAVEN is slated to blast off atop an Atlas V rocket from Cape Canaveral Florida on Nov. 18, 2013. It will join NASA’s armada of four robotic spacecraft when it arrives at Mars during 2014.

MAVEN is the first spacecraft devoted to exploring and understanding the Martian upper atmosphere. The spacecraft will investigate how the loss of Mars’ atmosphere to space determined the history of water on the surface.

But don’t dawdle- the deadline for submissions is July 1.

So, sign up to ‘Go to Mars’ – and do it NOW!

Juice up your inner poet and post your ‘Haiku’ here – if you dare
