The Arkyd 100: Crowdfunding Space Exploraiton

ARKYD-in-SpacePlanetary Resources made quite the impression last year when they announced their plans to begin prospecting near-Earth asteroids with in the intention of mining them in the near future. Alongside such companies as SpaceX and Golden Spike, they are part of a constellations of private interests looking to establish commercial space travel and tourism. But their latest proposal goes a step further, bringing crowdfunding and the realm of space exploration together.

That’s the idea behind a Kickstarter campaign that the company began to raise money for a crowdfunded space telescope. Known as the Arkyd 100, the company claims that this new telescope will provide unprecedented public access to space and place the most advanced exploration technology into the hands of students, scientists and a new generation of citizen explorers.

asteroid_miningTo make their campaign successful, they need to raise $1 million in Kickstarter pledges by the end of June 2013. Once the telescope is up and running, it will allow them to better map the asteroid belt, thus assisting them in finding the rocks they want to mine for precious metals and trace elements. And with public financial backers making it happen, anyone pledging money will be able to own a piece of the prospector!

During a webcast on May 28th to announce the Kickstarter campaign, Chris Lewicki, President and Chief Engineer for Planetary Resources, gave a rundown on the details of the telescope. And interestingly enough, the Planetary Resources’ technical team that designed it also worked on every recent U.S. Mars lander and rover. So if you do choose to invest, you will do so with the knowledge that the same people who helped build the Opportunity and Curiosity rovers are behind this project. If that doesn’t inspire investor confidence, I don’t know what will!

ARKYD-Space-SelfieA wide array of scientists, space enthusiasts and even Bill Nye the Science Guy have voiced their support for Planetary Resources’ new public space telescope. And those who invest will have the chance of recouping certain rewards, depending on how much they choose to pledge. Those pledging the minimum donation of $25 will receive the “Your Face in Space” benefit, where you will have you picture placed on the Arkyd and receive a picture of said photo the telescope with Earth in the background. Higher pledges will provide access to the telescope for students and researchers worldwide.

After less than 2 hours into their campaign, Planetary Resources had raised over $100,000. And as of this article’s writing, just one day shy of a week, the campaign has reached $710,945 of their $1 million goal, and they still have 27 days left. I guess people want a piece of this project. And who can blame them, since it is a scientific and historic first!

Opportunity Finds Evidence of Life!

opportunityThe Opportunity Rover is at it again! A little over a week ago, it set the record for longest distance traveled by a vehicle on another planet. Well it seems that NASA’s longest-running rover wasn’t finished hogging the limelight just yet. Yes, after ten years of service on what was originally planned to be a three-month journey, Opportunity struck gold by discovering the strongest evidence to date for an environment favorable to ancient Martian biology.

It began just two weeks ago, when Opportunity conducted an analysis of a new rock target named “Esperance”. According to a statement released by NASA, the rover confirmed that the rock target was composed of a “clay that had been intensely altered by relatively neutral pH water – representing the most favorable conditions for biology that Opportunity has yet seen in the rock histories it has encountered.”

Opportunity-Sol-3309_Aa_Ken-Kremer-580x288The process involved Opportunity using it still-functioning Rock Abrasion Tool (RAT) to expose the interior of Esperance and then examine it with its microscopic camera and X-Ray spectrometer, both of which that are mounted at the end of her nearly 1 meter (3 foot) long robotic arm. Inside, it found a rock surface loaded with clay minerals that was clearly formed with the help of flowing liquid water.

The robot made the discovery at the conclusion of a 20 month long science expedition circling around a low ridge called “Cape York”, a region of great important to Mars scientists. Scott McLennan of Stony Brook University, a long-term planner for Opportunity’s science team, explained why:

What’s so special about Esperance is that there was enough water not only for reactions that produced clay minerals, but also enough to flush out ions set loose by those reactions, so that Opportunity can clearly see the alteration.

opportunity_esperanceEsperance is unlike any rock previously investigated by Opportunity, containing far more aluminum and silica which is indicative of clay minerals and lower levels of calcium and iron. Most, but not all of the rocks inspected to date by Opportunity were formed in an environment of highly acidic water that is extremely harsh to most life forms. Clay minerals typically form in potentially drinkable, neutral water that is not extremely acidic or basic.

These findings amount to the discovery of an environment in which life could have thrived, which amounts to a scientific home run for the senior rover. As Prof. Steve Squyres of Cornell University, the mission’s principal scientific investigator, put it:

Water that moved through fractures during this rock’s history would have provided more favorable conditions for biology than any other wet environment recorded in rocks Opportunity has seen.

What’s next for Opportunity? Well, now that she’s finished at Cape York, Opportunity has set sail for her next crater destination at “Solander Point”, an area about 2.2 km (1.4 miles) south of the Cape. Eventually, she will continue further south to a rim segment named “Cape Tribulation” which holds huge caches of clay minerals. Along the way, there’s likely to be plenty more evidence of what Mars looked like many millions of years ago.

You know, with all this Opportunity-related news coming in, I’m beginning to wonder what Curiosity is up to. While it’s nice to see her partner-in-crime breaking records and turning up such important finds, I do wonder if Curiosity is likely to feel a little left out. At this rate, one might think a game of one-upmanship could break out between the rovers teams!

The Future is Here: The Real-Life Tricorder

medical_tricorderIt was only a matter of time, I guess. But we really should have known that with all the improvements being made in biometrics and biotechnology – giving patients and doctors the means to monitor their vitals, blood pressure, glucose levels and the like with tiny devices – and all the talk of how it looked like something out of science fiction that it wouldn’t be long before someone took it upon themselves to build a device right out of Star Trek.

It’s known as a the Scanadu Scout, a non-invasive medical device that is capable of measuring your vitals simply by being held up to your temple for a mere 10 seconds. The people responsible for its creation are a startup named Scanadu, a group of research and medtech enthusiasts who are based at the NASA Ames Research Center. For the past two years, they have been seeking to create the world’s first handheld medical scanner, and with the production of the Scout, they have their prototype!

scanaduAll told, the device is able to track pulse transit time (to measure blood pressure), temperature, ECG, oximetry, heart rate, and the breathing rate of a patient or subject. A 10 second scan of a person’s temple yields data that has a 99% accuracy rate, which can then be transmitted automatically via Bluetooth to the user’s smartphone, tablet or mobile device.

The device has since been upgraded from its original version and runs at a rate of 32 bits (up from the original 8). And interestingly enough, the Scouts now runs on Micrium, the operation system that NASA uses for Mars sample analysis on the Curiosity rover. The upgrade became necessary when Scanadu co-founder Walter De Brouwer, decided to add an extra feature: the ability to remotely trigger new algorithms and plug in new sensors (like a spectrometer).

medtechOne would think that working with NASA is effecting his thinking. But as Brouwer points out, the more information the machine is capable of collecting, the better is will be at monitoring your health:

If we find new algorithms to find relationships between several readings, we can use more of the sensors than we would first activate. If you know a couple of the variables, you could statistically predict that something is going to happen. The more data we have, the more we can also predict, because we’re using data mining at the same time as statistics.

One of the Scout’s cornerstone algorithms, for example, allows it to read blood pressure without the inflating cuff that we’ve all come to know and find so uncomfortable. In the future, Scanadu could discover an algorithm that connects, age, weight, blood pressure, and heart rate with some other variable, and then be able to make recommendations.

2009_world_subdivisions_flu_pandemicEveryone who pre-orders a Scout has their data sent to a cloud service, where Scanadu will collect it in a big file for the FDA. Anyone who opts-in will also gain access to the data of other users who have also elected to share their vitals. Brouwer explains that this is part of the products early mission to test the parameters of information sharing and cloud-medical computing:

It’s going to be a consumer product in the future, but right now we are positioning it as a research tool so that it can be used to finalize the design and collect data to eventually gain regulatory approval. In the end, you have to prove how people are going to use the device, how many times a day, and how they are going to react to the information.

In the future, De Brouwer imagines this kind of shared information could be used for population scanning, kind of like Google Flu Trends does, except with data being provided directly from individuals. The focus will also be much more local, with people using the Scout’s stats to able to see if their child, who suddenly has flu symptoms, is alone of ir other kids at their school are also sick. Pandemics and the outbreaks of fatal diseases could also be tracked in the same way and people forewarned.

medical-technologyNaturally, this raises some additional questions. With it now possible to share and communicate medical information so easily between devices, from people to their doctors, and stored within databases of varying accessibility, there is the ongoing issue of privacy. If in fact medical information can be actively shared in real-time or with the touch of a button, how hard will it be for third parties to gain access to them?

The upsides are clear: a society where health information is easily accessible is likely to avoid outbreaks of infectious disease and be able to contain pandemics with greater ease. But on the flip side, hackers are likely to find ways to access and abuse this information, since it will be in a public place where people can get at it. And naturally, there are plenty of people who will feel squeamish or downright terrified about the FDA having access to up-to-the-moment medical info on them.

It’s the age of cloud computing, wireless communications, and information sharing my friends. And much as people feel guarded about their personal information now, this is likely to take on extra dimensions when their personal medical info is added to the mix. Not a simple or comfortable subject.

But while I’ve still got you’re here, no doubt contemplating the future of medicine, take a look at this video of the Scanadu Scout in action:

News From Space: Opportunity Hits New Record!

opportunityWith the Curiosity Rover blazing a trail across Mars to find evidence of what the planet once looked like, people often forget about it’s venerable predecessor – the Opportunity Rover. Luckily, Opportunity recently broke a record that put it back in the public eye and into the history books. After nine years into what was initially meant to be a 90 day mission, Opportunity smashed yet another space milestone this week by establishing a new distance driving record.

On Thursday, May 16, the Opportunity rover drove another 80 meters (263 feet) on the Martian surface, bringing her total odometry since landing on the 24th of January, 2004 to 35.760 kilometers (22.220 miles). This effectively put her ahead of the 40 year old driving record set by the Apollo 17 astronauts Eugene Cernan and Harrison Schmitt back in December of 1972.

Apollo_17_lunar-rover-577x580On that mission, Cernan and Schmitt performed America’s final lunar landing mission and drove their Lunar Roving Vehicle (LRV-3) a total of 35.744 kilometers (22.210 miles) over the course of three days on the moon’s surface at the Taurus-Littrow lunar valley. And interestingly enough, Cernan was a very good sport about his record being broken. In a statement made at NASA’s Goddard Space Flight Center in Greenbelt, Md, he said:

The record we established with a roving vehicle was made to be broken, and I’m excited and proud to be able to pass the torch to Opportunity.

And since Opportunity still has plenty of juice left, it is now eying the ‘Solar System World Record’ for driving distance on another world, a record that is currently held by the Soviet Union’s remote-controlled Lunokhod 2 rover. In 1973, Lunokhod 2 traveled 37 kilometers (23 miles) on the surface of Earth’s nearest neighbor. With Opportunity setting course for her next crater rim destination, named “Solander Point”, she is likely to overtake Lunokhod 2’s record in short order!

Opportunity-Route-Map_Sol-3309_Ken-Kremer-580x336Thereafter, Opportunity will rack up ever more distance as the rover continues driving further south to a spot called “Cape Tribulation”. This point is believed to hold caches of clay minerals that formed eons ego when liquid water flowed across this region of the Red Planet. In so doing, Opportunity will not only establish a new record that will last for years to come, it will also be obtaining data that will assist in Curiosity’s own efforts to determine what life was like on Mars in the past.

Far greater than this record-breaking news is the fact that Opportunity has lasted so far beyond her design lifetime, 37 times longer in fact than her initial 3 month “warranty”.

And be sure to check out the full list of record holders for “out-of-this-world” driving, below:

News from the Red Planet: Mars’ Bygone Atmosphere

??????In this latest video update from the Mars Science Laboratory team, Ashwin Vasavada, the mission’s Deputy Project Scientist, discusses the recent findings by the Curiosity Rover. As always, these include ongoing studies of Mars atmosphere, in addition to soil and rock analysis, to determine what the Martian landscape may have looked like millions of years ago.

And in its latest research breakthrough, the rover has determined that Mars doesn’t have the same atmosphere it used to. Relying on its microwave oven-sized Sample Analysis at Mars (SAM) instrument, the rover analyzed a sample of Martian air early in April, and the results that came back provided the most precise measurements ever made of in the Martian atmosphere.

SolarConjunctionWhat it noticed in particular was the isotopes of Argon, a basic element that is present in Earth’s atmosphere, Jupiter’s and even the Sun. In Mars case, the mix of light and heavy Argon – two different isotopes of the element – is heavier than in all the other cases. What this suggests is that the Martian atmosphere has thinned over the course of the past few million years.

This data conclusively confirms another long-held suspicion by scientists, that Mars did indeed have an atmosphere capable of supporting life. Alongside the voluminous evidence obtained by Curiosity for the existence of water, we now know that Mars may have supported life at one time, and that it did not always have the arid, cold climate it now does. More good news for those looking to build a case for settling there one day…

solarConjunction02Check out the video below to hear Ashwin Vasavada speak about these latest findings, including the Solar Conjunction which kept them from communicating with the Rover until today. Now that the conjunction has ended, we can expect plenty more updates and interesting finds from the rover. Who knows? Maybe even some evidence about the existence of a Martian civilization.

Don’t be looking at me like that! It could happen…

News From Space: The NASA-Funded Fusion Rocket

fusion-rocket-university-of-washington-640x353NASA scientists have been saying for some time that they plan to send a manned mission to Mars by 2030. At the same time, space adventurist Dennis Tito and his company Inspiration Mars want to send a couple on a flyby of the Red Planet in 2018. With such ambitions fueling investment and technological innovation, its little wonder why people feel we are embarking on the new era of space exploration.

However, there is one sizable problem when it comes to make the Mars transit, which is the wait time. In terms of Tito’s proposed flyby, a trip to Mars when it is in alignment with Earth would take a total 501 days. As for NASA’s round-trip excursions for the future, using current technology it would take just over four years. That’s quite the long haul, and as you can imagine, that longer transit time has an exponential effect on the budgets involved!

Mars_landerBut what if it were possible to cut that one-way trip down to just 30 days. That’s the question behind the new fusion rocket design being developed at the University of Washington and being funded by NASA. Led by John Slough, this team have spent the last few years developing and testing each of the various stages of the concept and is now bringing the isolated tests together to produce an actual fusion rocket.

The challenge here is to create a fusion process that generates more power than it requires to get the fusion reaction started, a problem which, despite billions of dollars of research, has eluded some of the world’s finest scientists for more than 60 years. However, researchers continue to bang their head on this proverbial wall since fusion alone – with its immense energy density – appears to be the way of overcoming the biggest barrier to space travel, which is fuel weight and expense.

spacecraft_marsUltimately, the UW fusion rocket design relies on some rather simple but ingenious features to accomplish its ends. In essence, it involves a combustion chamber containing rings made of lithium and a pellet of deuterium-tritium – a hydrogen isotope that is usually used as the fuel in fusion reactions. When the pellet is in the right place, flowing through the combustion chamber towards the exhaust, a huge magnetic field is triggered, causing the metal rings to slam closed around the pellet of fuel.

These rings then implode with such pressure that the fuel compresses into fusion, causing a massive explosion that ejects the metal rings out of the rocket and at 108,000 km/h (67,000 mph) and generating thrust. This reaction would be repeated every 10 seconds, eventually accelerating the rocket to somewhere around 320,000 km/h (200,000 mph) — about 10 times the speed of Curiosity as it hurtled through space from Earth to Mars.

NASA_fusionchamberHowever, things still remain very much in the R&D phase for the fusion rocket. While the team has tested out the imploding metal rings, they have yet to insert the deuterium-tritium fuel and propel a super-heated ionized lump of metal out the back at over 100,000 kilometers and hour. That is the next – and obviously a very, very – big step.

But in the end, success will be measured when it comes to two basic criteria: It must work reliably and, most importantly, it must be capable of generating more thermal energy than the electrical energy required to start the fusion reaction. And as already mentioned, this is the biggest challenge facing the team as it is something that’s never been done before.

However, most scientific minds agree that within 20 years at least, fusion power will be possible, and the frontiers it will open will be vast and wonderful. Not only will we be able to fully and completely lick the problem of clean energy and emissions, we will have rockets capable of taking us to Mars and beyond in record time. Deep space flight will finally become a possibility, and we may even begin considering sending ships to Alpha Centauri, Bernard’s Star and (fingers crossed!) Gliese 581!

News From Space: MESSENGER and Mercury

messengerWith Curiosity’s ongoing research and manned missions being planned for Mars by 2030, it seems that the other planets of the Solar System are being sadly neglected these days. Thankfully, the MESSENGER spacecraft, which has been conducting flyby’s of Mercury since 2008 and orbiting it since 2011, is there to remind us of just how interesting and amazing the planet closest to our sun truly is.

And in recent weeks, there has been a conjunction of interesting news stories about Earth’s scorched and pockmarked cousin. The first came in March 22nd when it was revealed that of the many, many pictures taken by the satellite (over 150,000 and counting), some captured a different side of Mercury, one which isn’t so rugged and scorched.

Messenger_smooth1The pictures in question were of a natural depression located northeast of the Rachmaninoff basin, where the walls, floor and upper surfaces appear to be smooth and irregularly shaped. What’s more, the  velvety texture observed is the result of widespread layering of fine particles. Scientists at NASA deduced from this that, unlike many features on Mercury’s  ancient surface, this rimless depression wasn’t caused by an impact from above but rather explosively escaping lava from below.

In short, the depression was caused by an explosive volcanic event, which left a hole in the surface roughly 36 km (22 miles) across at its widest. It is surrounded by a smooth blanket of high-reflectance material, explosively ejected volcanic particles from a pyroclastic eruption, that spread over the surface like snow. And thanks to Mercury’s lack of atmosphere, the event was perfectly preserved.

Messenger_smooth2

Other similar vents have been found on Mercury before, like the heart-shaped depression observed in the Caloris basin (seen above). Here too, the smooth, bright surface material was a telltale sign of a volcanic outburst, as were the rimless, irregular shapes of the vents. However, this is the first time such a surface feature has been captured in such high-definition.

And then just three days later, on March 25th to be exact, Mercury began to experience its greatest elongation from the Sun for the year of 2013. In astronomy, this refers to the angle between the Sun and the planet, with Earth as the reference point. When a planet is at its greatest elongation, it is farthest from the Sun as viewed from Earth, so its view is also best at that point.

Mercury_31-03-13_0630What this means is that for the remainder of the month, Mercury will be in prime position to be observed in the night sky, for anyone living in the Northern Hemisphere that is. Given its position relative to the Sun and us, the best time to observe it would be during hours of dusk when the stars are still visible. And, in a twist which that may hold cosmic significance for some, people are advised to pay special attention during the morning of Easter Day, when the shining “star” will be most visible low in the dawn sky.

And then just three days ago, a very interesting announcement was made. It seems that with MESSENGERS ongoing surveys of the Hermian surface, nine new craters have been identified and are being given names. On March 26th, the International Astronomical Union (IAU) approved the proposed names, which were selected in honor of deceased writers, artists and musicians following the convention established by the IAU for naming features on the innermost world.

crater_names

The announcement came after MESSENGER put the finishing touches on mapping the surface of Mercury earlier this month. A good majority of these features were established at Mercury’s southern polar region, one of the last areas of the planet to be mapped by the satellite. And after a submission and review process, the IAU decided on the following names of the new craters:

Donelaitis, named after 18th century Lithuanian poet Kristijonas Donelaitis, author of The Seasons and other tales and fables.

Petofi, named after 19th century Hungarian poet Sandor Petofi, who wrote Nemzeti dal which inspired the Hungarian Revolution of 1848.

Roerich, named after early 20th century Russian philosopher and artist Nicholas Roerich, who created the Roerich Pact of 1935 which asserted the neutrality of scientific, cultural and educational institutions during time of war.

Hurley, named after the 20th century Australian photographer James Francis Hurley, who traveled to Antarctica and served with Australian forces in both World Wars.

Lovecraft, named after 20th century American author H.P. Lovecraft, a pioneer in horror, fantasy and science fiction.

Alver, named after 20th century Estonian author Betti Alver who wrote the 1927 novel Mistress in the Wind.

Flaiano, named after 20th century Italian novelist and screenwriter Ennio Flaiano who was a pioneer Italian cinema and contemporary of Federico Fellini.

Pahinui, named after mid-20th century Hawaiian musician Charles Phillip Kahahawai Pahinui, influential slack-key guitar player and part of the “Hawaiian Renaissance” of island culture in the 1970’s.

L’Engle, named after American author Madeleine L’Engle, who wrote the young adult novels An Acceptable Time, A Swiftly Tilting Planet & A Wind in the Door. L’Engle passed away in 2007.

Crater_names_August2012-580x376The campaign to name Mercury’s surface features has been ongoing since MESSENGER performed its first flyby in January of 2008. Some may recall that in August of last year, a similar process took place for the nine craters identified on Mercury’s North Pole. Of these, the names of similarly great literary, artistic and scientific contributors were selected, not the least of which was Mr. J RR Tolkien himself, author of Lord of the Rings and The Hobbit!

It’s no secret that the MESSENGER spacecraft has been a boon for scientists. Not only has it allowed for the complete mapping of the planet Mercury and provided an endless stream of high resolution photos for scientists to pour over, it has also contributed to a greater understanding of what our Solar System looked like when it was still in early formation.

Given all this, it is somewhat sad that MESSENGER is due to stand down at the end of the month, and that the next mission to Mercury won’t be until 2022 with the planned arrival of the joint ESA/JAXA BepiColombo mission. But of course, we can expect plenty of revelations and stories to emerge from all the scientific data collected on this latest trip. And I’m sure Mars will be more than willing to provide ample entertainment until 2022 comes to pass!

While we’re waiting, be sure to check out this informative video of MESSENGER’s contributions over the past few years:

Life-Giving Elements Found on Mars!

Curiosity_drillingsCuriosity has just finished analyzing the samples collected from its first drilling operation at the John Klein rock formation in Yellowknife Bay. And what it found confirms what scientists have suspected about the Red Planet for some time. Contained within grey the dust collected from the rock’s interior, the rover discovered some of the key chemical ingredients necessary for life to have thrived on early Mars billions of years ago.

After running the two aspirin-sized samples through its two analytical chemistry labs (SAM and CheMin), the Mars Science Laboratory was able to identify the presence of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus in the sample – all of which are essential constituents for life as we know it based on organic molecules.

Curiosity_chemWhat’s more, according to David Blake – the principal investigator for the CheMin instrument – a large portion of the sample was made up of clay minerals, which in itself is telling. The combined presence of these basic elements and abundant phyllosilicate clay minerals indicate that the area was once home to a fresh water environment, one where Martian microbes could once have thrived in the distant past.

By confirming this, the Curiosity Rover has officially met one of its most important research goals – proving that all the elements necessary for life to flourish were once present on Mars. And when you consider that the Curiosity team was not expecting to find evidence of phyllosilicate minerals in the Gale Crater, the find was an especial delight. Based on spectral observations conducted from orbit, phyllosilicates were only expected to be found in the lower reaches of Mount Sharp, which is Curiosity’s ultimate destination.

Curiosity-Sol-169_5C1b_Ken-KremerSo what’s next for Curiosity? According to John Grotzinger, the Principal Investigator for the Mars Science Laboratory, Curiosity will remain in the Yellowknife Bay area for several additional weeks or months to fully characterize the area. The rover will also conduct at least one more drilling campaign to try and replicate the results, check for organic molecules and search for new discoveries.

More News from Mars… Lots More!

marsIt’s a good thing I’ve come down with a cold and have little to do but sit at my computer. Because in the last week, some very interesting news stories have been piling up that just scream for recognition. And wouldn’t you know it, more than a few have to do with our big red neighbor Mars, that world many human beings will one day think of as home.

The first story comes to us from the Siding Spring Observatory in New South Wales, where noted astronomer Robert McNaught recently sighted an new comet. From his observations, the icy interloper appeared to have originated in the Oort Cloud – a hypothetical cloud surrounding the solar system and containing billions of icy planetesimals that were cast out from our Solar System billions of years ago.

Mars_A1_Latest_2014After news of the discovery was released, the astronomers at the Catalina Sky Survey in Arizona looked back over their observations to find “prerecovery” images of the comet dating back to Dec. 8, 2012. These observations placed the orbital trajectory of the comet – now known as C/2013 A1 – through the orbit of Mars on Oct. 19, 2014. This means, in essence, that this comet could very well strike the Red Planet late next year.

Luckily, NASA’s Jet Propulsion Laboratory has run the calculations and indicated that their close approach data suggests the comet is most likely to make a close pass of the Martian surface. And by close, they mean at roughly 0.0007 AU, or approximately 100,000 kilometers (63,000 miles) from the Martian surface. So in all likelihood, Curiosity and Opportunity will be safe from a serious impact that could turn them into scrap metal!

But of course, predicting its exact trajectory at this time is subject to guess work, and ongoing observations will be needed. No doubt, the predictions will be refined a the next 20 months go by, and we’ll know for sure if this comet plans to miss Mars completely, or slam head-on into the surface at 200,000 km/h (126,000 mph).

Mars_curiosity_drillingThe second bit of news comes to us from the good-ole Curiosity Rover! Roughly four weeks after conducting the first drilling operation into the Martian surface, the Rover ate its first sample of the grey dust that resulted. The delivery of the two aspiring-sized tablets of dust took place on Feb. 22nd and 23rd respectively after the robotic arm delivered them into the rover’s Chemistry and Mineralogy (CheMin) and Sample Analysis at Mars (SAM) laboratories for analysis. Results expected in two weeks!

Among other things, the results from the analysis are expected to give clues as to what the color change between the red surface and the grey interior means. One theory is that it might be related to different oxidations states of iron that could potentially inform us about the habitability of Mars inside the rover’s Gale Crater landing site.

Living-Mars.2At the same time, the Mars Science Laboratory team expects to find further evidence of what life was like in previous geological eras. The Curiosity team believes that the area inside the Gale Crater, known as Yellowknife Bay, experienced repeated exposure to flowing liquid water long ago when Mars was warmer and wetter – and therefore was potentially more hospitable to the possible evolution of life.

The rover will likely remain in the John Klein area for a month or more to obtain a more complete scientific characterization of the area which has seen repeated episodes of flowing water. Eventually, the six-wheeled mega rover will set off on a year long trek to her main destination: the sedimentary layers at the lower reaches of the  5 km (3 mile) high mountain named Mount Sharp.

mars_hieroglyphsAnd last, but not least by any stretch of the imagination, is the discovery of “hieroglyphs” on the Martian surface. While they might appear like ancient glyphs to the untrained eye, they are in fact evidence of past subsurface water. The images were caught by the HiRISE camera on the Mars Reconnaissance Orbiter as it passed the surface area known as Amazonis Planitia.

Known as ‘rootless cones,’ these geological features are the result of an explosive interaction of lava with ground ice or water contained within the regolith beneath the flow. Vaporization of the water or ice when the hot lava comes in contact causes an explosive expansion of the water vapor, causing the lava to shoot upward, creating what appears to be a button hole on the surface.

rootlessConesIn the past, Mars scientists have used geological patterns on Earth to make sense of similar ones found on Mars. For example, when the Curiosity Rover discovered veins of hydrated calcium in the rock surface in the Gale Crater, they compared them to similar patterns found in Egypt to determine that they were the result of long-term exposure to water flows. In this case, the rootless cones found in Amazonis Planitia are comparable to those found in Iceland’s Laki Lava Flow (as seen above).

According to Colin Dunas, from the US Geological Survey, the cones are rather large and most likely very old:

“The cones are on the order of a hundred meters across and ten meters high. The age of these specific cones isn’t known. They are on a mid- to late-Amazonian geologic unit, which means that they are young by Martian standards but could be as much as a few hundred million to over a billion years old.”

terraformingOnly time will tell if any subsurface water is still there, and hence usable by future teams of terraformers and settlers. According to Dundas, the odds are not so good of that being the case. Given the surface depth at which the ice was found, not to mention that at the low latitude at which it was found (22 degrees north), shallow ground ice is unstable. Dundas added that since ice stability varies as the obliquity changes, it’s even possible that ice has come and gone repeatedly since the lava erupted.

Too bad. That could have come in really handy for hydroponics, fuel cells, and even restoring surface water to the planet. Guess future generations of Martians will just have to look for their ground and irrigation water elsewhere, huh? Just another challenge of converting the Red Planet to a green one, I guess 😉

Stay tuned for more news Mars. As it stands, there’s plenty to be had! Stick around!

Interactive Panorama of Curiosity!

Curiosity_selfportraitThe credit goes to photographer Andrew Bodrov for creating this new and stunning  interactive self-portrait of the Curiosity Rover. Relying on several recent images taken at the “John Klein” drilling sight, he was able to create a full 360-degree panorama. What’s more, the picture is interactive, giving viewers the option of clicking, zooming, and surveying the entire “John Klein” drilling sight.

The mosaic stretches about 30,000 pixels width and includes the self-portrait, which consists of 66 different images (seen above) taken by the rover’s Mars Hand Lens Imager (MAHLI) during the 177th Martian sol, of Curiosity’s work on Mars (Feb. 3, 2013 here on Earth), along with 113 images taken on Sol 170 and an additional 17 images taken on Sol 176.

curiosity_sol-177-1The full and non-interactive photo appears above. If you look closely, you can see the drill holes directly beneath the rover. In addition, the shiny protuberance which was noticed earlier this month. And if you pan around the sky, you get a look at what a typical Martian day looks like, at least in Yellowknife Bay.
