Good News! Stories from Space Picked up by ITSP Magazine!

This news has been a few months in the making, but with the final preparations underway, I feel like it’s time to announce it! In a few weeks, I will be launching my podcast series – Stories from Space – with the Intersection Of Technology, Cybersecurity, And Society Podcast (ITSP), a highly-respected channel that hosts multiple shows. Each of these is dedicated to exploring the past, the present, and the future of humanity’s relationship with technology and the profound effects it can have on our society.

Almost Done!

Almost Done!

Hey all! I have more in the way of novel-writing news. For starters, The Cronian Incident is now just a few chapters short of completion. After over a year of writing, editing, and back and forth with my prospective-publisher, the novel is just about finished. All told, it is now 31 chapters long and just over 85,000 words in length. I anticipate it will be about 100,000 by the time its finished, though I have been known to exceed estimates in the past!

And as per my agreement with my publisher, I have begun working on its sequel. Apparently, publishers like to know the people they sign have more books in them. And they prefer to release sequels within a few months of the first book, to ensure that any buzz they generate with the first release can be capitalized on. Lucky for me I had plans for a second and third novel before my publisher and I started talking, not to mention some spin offs.

So here’s the commercial description for the proposed sequel (i.e. what you’d read on the back of the dust jacket), as well as a rundown on some other ideas I’m working on:

The Jovian Manifesto:

The Solar System is in the midst of a crisis. In the Jovian and Cronian systems, the populations are up in arms, thanks to an inflammatory document that has appeared on the local nets. Known as “The Jovian Manifesto”, this document details how a powerful faction in the Inner Solar System conspired to seize control over the moons of Callisto and Titan and forcibly alter them. Behind the leak is a mysterious personality known only as Clio, who is threatening to release all the details unless the guilty parties come forward.

Back on Venus, a former analyst named Valéria Gallego is called before the Solar Assembly to investigate the Manifesto and its author. In this, she is assisted by Kadera, an infiltration specialist who can get in and out of any location in the Solar System. If they can determine its authenticity, perhaps they can prevent open conflict. But if not, the Inner Worlds may have no choice but to send armed forces to the Outer Worlds to ensure peace and stability.

Meanwhile, a string of violent acts has threatened to bring things ever closer to the brink. For Gallego and all those who are seeking the truth, time is running out…

Luna Invictus:

Now this is a book that doesn’t come with a commercial description, just a general one. But it is set in the same universe as The Cronian Incident and The Jovian Manifesto. Here’s what I am thinking. Basically, I wanted to do a story set on the Moon, ca. the 22nd century, when the Moon is now effectively colonized,,,

Between the European Space Agency (ESA), NASA, the Russians (Roscosmos), India (the ISRO), and China (CNSA), the lunar surface now has multiple permanent settlements. Whereas the ESA and NASA have established themselves at the southern polar region – in a domed settlement in the Shackleton Crater – and the Chinese have established a colony in the northern polar region, the Russians and Indians have claimed the mid-latitudes, where stable lava tubes have allowed for the creation of underground cities.

And on the “Dark Side” of the Moon – that is to say, the side looking away from Earth – are a series of installations known as the Unrestricted Zones. It is here that all kinds of weird research, development and experiments take place. Nanotechnology, biotechnology, quantum computing, and man-machine interface – anything goes in these places! Ever since the explosion in learning that took place during the previous century, places all over Earth and the Moon have become dedicated to pursuing technological progress and integration without restriction.

And it is here that a young man named Frankling Houte is seeking to go. Years ago, his sister – named Constant Houte – chose to undergo a procedure where her organic brain would be augmented by merging it with quantum components. But after all contact ceased, he is determined to find her and return her home. But whereas Franklin fancies himself a brave rescuer, it is his sister who will come to save him.

Transverse:

This story will take place entirely in a generation ship that is making its way towards the nearby star system. Within the confines of this self-contained world, thousands of humans have committed to waiting and working for generations as their massive ship – the Traverse Velocity, which in astronomical terms refers to the speed at which a star moves perpendicular to our line of sight – transports them to an Earth-like world outside of our Solar System.

The location of that world is up for grabs at the moment, mainly because new discoveries are being made all the time. Did you hear about the latest exoplanet discovery, located about 39 light years away and already said to be the “best place to look for signs of life beyond the Solar System”? Between that and new findings that claims how previous discoveries are not likely to be habitable after all, I’ve decided to leave the destination blank until I actually start writing it!

But of course, no story would be complete without some intrigue and big ol’ inciting event! And the way I see it, things begin to go awry when the Captain and crew get notification that one of the passengers has awakened from cryosleep prematurely and disappeared into the ship. Shortly thereafter, one of the crew is found dead in what appears to be a sabotage attempt gone wrong. A ship-wide search begins to find the culprit while the atmosphere quickly devolves into one of paranoia and suspicion.

To make matter worse, the crew becomes aware of another ship that is threatening to catch up and overtake them. It seems that another faction from the Solar System, which was also intent on settling (insert exoplanet here) is now trying to get their ahead of them. What began as a journey to a new world, characterized by hopes and dreams, has become a race to lay claim to a planet. And it appears that the planet may have inhabitants of its own, ones which are not interested in welcoming the intruders.

New Movie Trailer: The Martian

the_martianThe latest trailer for the The Martian has just hit cyberspace! And as you can see, its quite the doozy. Based on the novel by Andy Weir, The Martian tells the story of Mark Watney – a botanist and space engineer who is part of a manned mission to Mars. When an unexpected storm strikes in the course of that mission, Watney is lost during evacuation and presumed dead.

However, the crew soon learns that Watney survived the storm and has been living on the planet ever since. With a return mission expected to take years before it can reach him, NASA must struggle with a terrible dilemma – risk the lives of many astronauts to save one, or let Watney die alone on a distant planet?

I will definitely seeing this movie, but not before I read the original novel! And I can proudly say that after learning about this movie, I ordered a copy of the book a few weeks back and it now sits on my nightstand. I still got finish a few things before getting to it, but I plan to have it read before the movie comes out in October. There is no way in hell I’ll be waiting for this movie to come out on DVD or Netflix!

Aerospace Travel: Los Angeles to Tokyo in One Hour

spaceshiptwo_flightGiven my busy schedule of late, some stories have been sitting in my stack for some time and I haven’t been able to write about them. But one’s like this are too cool to pass up, so here’s a belated acknowledgement. It seems that Virgin Galactic, having now demonstrated its ability to conduct aerospace tourism, has decided to enter into phase two of its plans for the future: aerospace travel!

In the scenario they are proposing, their planes would fly customers from Los Angeles to Tokyo, and the transit would take one hour. The takeoff system would be similar to the midair launch the company uses now with the SpaceShipTwo. Basically, a large plane flies the spacecraft off the ground, drops it in midair, a hybrid rocket engine ignites, and the spacecraft ascends into lower orbit.

spaceshiptwo-2nd-flight-2A system like this would allow patrons to fly from the West Coast to Japan in an hour, or from the United Kingdom to Australia in two hours. This is according to statements made by Virgin Galactic’s CEO, George Whitesides, back in September at a company event at New York City’s Museum of Natural History:

You can imagine a SpaceShipThree or a SpaceShipFour going outside the atmosphere, then coming back down outside an urban area and landing. We don’t have to accept the status quo. We can imagine a vehicle using liquid oxygen or liquid hydrogen to get us across the Pacific in an hour. You could do that.

For those following Branson’s exploits, this announcement should come as no surprise. For years, he has been attempting to create a supersonic airline of his own. But when a paradigm-shifting idea like “point-to-point suborbital space transportation” becomes possible, he began to sets his sights a little higher (so to speak).

Spaceshiptwo-580x256Naturally, there are a few things that need to be worked out and tested before that’s possible, but it’s entirely within the realm of possibility. In fact, the European Space Agency has been researching the idea and claimed that SpaceShipOne and SpaceShipTwo are the most promising space launch mechanisms they’ve seen to date.

Naturally, there is the nagging question of cost. If aerospace travel does become feasible, who exactly will be able to afford it? So far, Virgin Galactic’s suborbital spaceflight have attracted hundreds of customers, but at a cost of $250,000 per head. It seems unlikely that these same people would pay a quarter of a million dollars just to travel halfway around the world. And some experts maintain that the industry will fail strictly because of the costs involved.

space-trip-klmDerek Webber, is one such person. As the executive director of Spaceport Associates, he wrote a paper in 2008 that explored the idea:

Credible market studies have not been done, or at least published. The optimum technical design has not been established. The ground infrastructure is not in place… Price levels are uncertain. It is not even clear whether such flights are best characterized as tourism or as transportation; whether the passengers would be primarily tourists or business persons on urgent trips.

Nevertheless, these doubts are doing nothing to stem the flow of investment and research being made by aerospace organizations and companies. For years, KLM Royal Dutch Airlines – the national air carrier of the Netherlands – has been developing a rocket-powered sub-orbital craft of its own. California-based XCOR Aerospace also has the Lynx – a hypersonic plane that could fly between New York and Tokyo in just 90 minutes.

XCORReaction Engines Limited is also developing the Skylon hypersonic engine for commercial spacecraft, much in the same way that Boeing and NASA are  developing the X-37B space plane. While these efforts are aimed at creating reusable spacecraft that could deploy satellites and deliver crew and supplies into orbit, they are also laying the groundwork for commercial transportation that takes people into orbit.

Meanwhile, DARPA and the US Marine Corps have been working on developing their own point-to-point rockets for delivering supplies and people for roughly a decade now and the Federal Aviation Administration’s 2010 report noted that:

[the] potential for the rapid global transport of passengers and the fast distribution of goods and services make point-to-point transportation an attractive space technology concept worth exploiting.

So while a price breakdown may be lacking, and the expected costs limiting, the technology is still in its infancy and it seems likely that the future of transportation lies in space. Beyond rapid transit and space tourism, it may very well be how airlines ferry people to and from their destinations in the not-too-distant future.

Latest Articles Over At Universe Today!

center_universe2As the title would suggest, my third and fourth articles have just been published over at Universe Today. First off, let me assure people that I plan to post a link to UT in the near future so I don’t feel the need to do this every time a new article comes out. But since this is still a new experience to me, I naturally feel the need to share whenever a new one is published.

The first of the two, which was published on Monday, deals with a recent determination made about the source of the Moon’s water. This is based on research conducted by scientists over at the National Museum of Natural History in Paris. Back in 2009, India’s Chandrayaa-1 probe conducted a near-infrared survey of the Moon during a flyby that showed signs of surface water.

moon_waterAfter years of speculation that claimed that the surface water – which exists strictly in icy form – was deposited there by meteors and comets, the National Museum team concluded that its actually formed by solar wind interacting with oxygen in the Moon’s surface dust. Quite the odd little occurrence; but then again, even Mercury appears to have icy spots on it’s molten surface.

www.universetoday.com/115215/water-on-the-moon-was-blown-in-by-solar-wind/

The second is about a recent collaboration between NASA and SpaceX. While the latter was testing their Falcon 9 rockets, NASA filmed the performance using Infrared cameras. The information gleamed from this is helping SpaceX to develop their reusable rocket, but will also help NASA to figure out how they will land habitats and heavy equipment on the surface of Mars.

NASA_thermal1Sort of a win-win scenario, one that shows how the public and private sector are working together like never before to make the future of space exploration happen. And it’s another indication of just how serious NASA and its partners are in making a mission to Mars a reality.

Bad New from Mars: First Colonists Doomed!

Mars_exploreWith the exploration of Mars continuing apace and a manned missions looming, there has been an explosion of interest in the idea of one day settling the planet. As the non-profit organization known as Mars One can attest, many people are  interested in becoming part of a mission to colonize the Red Planet. In fact, when they first went public, some 200,000 people signed on to become part of the experience.

The fact that the trip would be one-way and that the  plans for getting them there did not yet exist was not an deterrent. But if a recent study from MIT is to be believed, those who choose to go will and have the experience televised will be in for a rather harsh experience. According to a feasibility study produced by researchers at the Institute, the plan has potentially deadly and astronomically expensive flaws.

mars_revelationspaceAfter analyzing the Mars One mission plan, the MIT research group found that the first astronaut would suffocate after 68 days. The other astronauts would die from a combination of starvation, dehydration, or incineration in an oxygen-rich atmosphere. The analysis also concludes that 15 Falcon Heavy launches – costing around $4.5 billion – would be needed to support the first four Mars One crew.

The technology underpinning the mission is rather nebulous; and indeed, that’s where the aerospace researchers at MIT find a number of potentially catastrophic faults. While the technology to set up a colony on Mars does technically exist, most of it is at a very low technology readiness level (TRL) and untested in a Mars-like environment. And the prediction that things will be worked out with time and crowdfunding does not appear to be sufficient.

Mars_one2Mars One will rely heavily on life support and in-situ resource utilization (ISRU) – squeezing water from Martian soil and oxygen from the atmosphere. But these technologies are still a long way off large-scale, industrial use by a nascent human colony on Mars. NASA’s next Mars rover will have an ISRU unit that will make oxygen from the Red Planet’s atmosphere of CO2 – but that rover isn’t scheduled to launch until 2020, just two years before the planned launch of Mars One.

Originally, Mars One’s sign-up list included some 200,000 candidates. That number has now been whittled down to 705 – a fairly even mix of men and women from all over the world, but mostly the US. Several teams of four astronauts (two men, two women) will now be assembled, and training will begin. The current plan is to send a SpaceX Falcon Heavy rocket carrying the first team of four to Mars in 2022 – just eight years from now. 

spaceX-falcon9The whole thing will be televised as a reality TV show, an instrinsic part of the plan since much of the funding is expected to come from media sponsors and advertisers. In the interim, a number of precursor missions – supplies, life-support units, living units, and supply units – will be sent to Mars ahead of the human colonizers. More colonists will be sent fairly rapidly thereafter, with 20 settlers expected by 2033.

The new feasibility study was led by Sydney Do, a PhD candidate at the Massachusetts Institute of Technology who has done similar studies on other space missions. Do and his team ran a computer simulation based on publicly available information about the Mars One plan and the kinds of technologies it would rely on. The researchers entered data about the crew’s age, weight and activities to find out how much food, oxygen and water they would need.

Mars_GreenhouseThey took into account information from Mars One, such as its plan that “food from Earth will only serve as emergency rations” and the astronauts will mainly eat fresh food they grow themselves. The simulation monitored conditions in the Mars One habitat over 26 months – the amount of time between spaceships from Earth that would resupply them – or until the death of a crew member, whichever came first.

The results of their study were presented in a paper at the International Astronomic Union conference in Toronto last month. They suggest that serious changes would need to be made to the plan, which would either call for the astronauts to grow all their plants in a unit isolated from the astronauts’ living space to prevent pressure buildup in the habitats, or import all food from Earth instead of growing it on Mars.

mars_one2The researchers recommend the latter, as importing all the necessary food along with the first wave of colonists (not including the costs of development, operations, communications, and power systems) would cost $4.5 billion and require 15 Falcon 9 Heavy Rockets to transport it. Comparatively, flying all the equipment needed for the astronauts to grow their own food indefinitely which cost roughly $6.3 billion.

On top of all that, Do and his research staff have concluded that the project will not be sustainable financially. While Mars One says each subsequent manned mission will cost $4 billion, Do’s study found that each mission would cost more than the one before, due to the increasing number of spare parts and other supplies needed to support an increasing number of people.

mars_roverNaturally, Mars One replied that they are not deterred by the study. CEO and co-founder Bas Landorp – who helped develop the mission design – said the plan was based on the company’s own studies and feedback from engineers at aerospace companies that make space systems, such as Paragon Space Development and Lockheed Martin. He added that he and his people are “very confident that our budgets, timelines and requirements are feasible”.

In any case, the study does not claim that the plan is bogus, just that it may be overreaching slightly. It’s not unreasonable to think that Mars One could get people to Mars, but the prospects for gradually building a self-sustaining colony is a bit farfetched right now. Clearly, more time is needed to further develop the requisite technologies and study the Martian environment before we start sending people to live there.

Mars_simulationOh well, people can dream can’t they? But the research and development are taking place. And at this point, it’s a foregone conclusion that a manned mission to Mars will be happening, along with additional robot missions. These will help lay the groundwork for eventual settlement. It’s only a question of when that could happen…

News from Space: We’re Going to Mars!

marsAs part of their desire to once again conduct launches into space from US soil, NASA recently awarded commercial space contracts worth $6.8 billion to Boeing and SpaceX. But beyond restoring indigenous spaceflight capability, NASA’s long-term aim is clearly getting a manned mission to Mars by 2030. And in assigning the necessary money to the companies and visionaries willing to help make it happen, they just might succeed.

As per the agreement, Boeing will receive $4.2 billion to finance the completion of the CST-100 spacecraft, and for up to six launches. Meanwhile, SpaceX is receiving $2.6 billion for its manned Dragon V2 capsule, and for up to six launches. NASA expressed excitement its collaboration with both companies, as it frees the agency up for bigger projects — such the development of its own Space Launch System (SLS).

elon-musk-on-mars-curiosity-self-640x353One person who is sure to be excited about all this is Elon Musk, SpaceX founder, CEO, and  private space visionary. With this big infusion of cash, he has apparently decided that it’s time to bring his plans for Mars forward. Ever since 2007, Musk has indicated a desire to see his company mount a manned mission to Mars, and now he may finally have the resources and clout to make it happen.

These plans include flying astronauts to Mars by 2026, almost a decade before NASA thinks it will. By late 2012, he even spoke about building a Mars Colony with a population in the tens of thousands, most likely established sometime during the 2020’s. As of this past year, he has also revealed details about a Mars Colonial Transporter (MCT), an interplanetary taxi that would be capable of ferrying 100 people at a time to the surface.

Fan art concept of the MCT
Fan concept art of the MCT

And then in February of this year, SpaceX began developing the MCT’s engines. Known as the Raptor, this new breed of large engine reportedly has six times the thrust of the Merlin engines that power the second stage of the Falcon 9 rocket. Now that the company has the financial resources to dream big, perhaps the MCT might move from the development stage to prototype creation.

And there is certainly no shortage of desire when it comes to sending people to the Red Planet. Together with Mars Society president Robert Zubrin, and Mars One co-founder Bas Lansdorp, crowdfunded organizations are also on board for a manned mission. The case for settling it, which Musk himself endorses, is a good one – namely, that planting the seed of humanity on other worlds is the best way to ensure its survival. 

Earth_Mars_ComparisonAnd as Musk has stated many times now, a manned mission Mars is the reason there is a SpaceX. Back in 2001, while perusing NASA’s website, he was perturbed to find that the space agency had nothing in the way of plans for a mission to Mars. And the best time to go is probably in about 15 or 20 years, since Mars will be at its closes to Earth by then – some 58 million kilometers (36 million miles).

During this window of opportunity, the travel time between Earth and Mars will be measured in terms of months rather than years. This makes it the opportune time to send the first wave of manned spacecraft, be they two-way missions involving research crews, or one-way missions involving permanent settlers. Surprisingly, there’s no shortage of people willing to volunteer for the latter.

Mars_one1When Mars One posted its signup list for their proposed mission (which is slated for 2025), they quickly drew over 200,000 applicants. And this was in spite of the fact that the most pertinent details, like how they are going to get them there, remained unresolved. Inspiration Mars, which seeks to send a couple on a round trip to Mars by 2021, is similarly receiving plenty of interest despite that they are still years away from figuring out all the angles.

In short, there is no shortage of people or companies eager to send a crewed spaceship to Mars, and federal agencies aren’t the only ones with the resources to dream big anymore. And it seems that the technology is keeping pace with interest and providing the means. With the necessary funding now secured, at least for the time being, it looks like the dream may finally be within our grasp.

Though it has yet to become a reality, it looks like the first Martians will actually come from Earth.

First Article Published at Universe Today!

bigelow-expandable-activity-moduleHey all! Just wanted to let people know, my first article for Universe Today just went public. The subject of the article was the Bigelow Expandable Activity Module, a new type of space habitat that is being shipped to the ISS next year. Researching and writing the article itself was not unusual for me. It’s pretty much what I do here every single day. However, the real fun came in speaking to NASA and Bigelow Aerospace themselves via phone and email.

Interviewing the people behind big ideas and technological innovation is something a humble blogger like myself doesn’t get to do!  While I’ve really enjoyed talking to luminaries like Andraka and Makosinski in the past, this was a first for me. Looking forward to doing more of it in the near future!

In any case, follow the link below to check it out and don’t forget to comment and Like us on Facebook… no pressure 😉

News from Space: “Life” Molecules Detected in Space!

SagitariusB2The secret to the creation to life in our universe appears to be seeding – the proper elements in the right mix in the right places to form the right kind of molecules. Only then can these molecules evolve chemically into more and more complex structures, thus following a general pathway toward biology. The pathway for life as we know it starts with carbon, but one which is specific organized and structured.

Recently, a team of astronomers  at the ALMA Observatory reported the discovery of this very element while probing distant galaxies. What they found was not just interstellar carbon, but a form of carbon with a branched structure. The discovery was made in the gaseous-star forming region known as Sagittarius B2 – a giant molecular cloud of gas and dust that is located about 390 light years from the center of the Milky Way.

radio-wave-dishesSimple carbon chains aren’t particularly unusual in the cosmos, but complex carbon is a different matter. It is what the researchers, based at Cornell University and the Max Planck Institute, describe as finding a molecular needle in a cosmic haystack. The actual molecule in question is isopropyl cyanide, and it was discerned thanks to the miracle known as radio astronomy.

Within clouds of interstellar dust and gas, elements find themselves shielded from the harsh radiation of open space and are, thus, free to form into more complex arrangements. These molecules don’t just sit there, but instead move around within their cloud-homes and bump into each other. The result of this activity are radio signals which can be detected light-years away – in this case, by radio telescopes here on Earth.

MaxPlanckIns_radiowavepulseEvery molecule has a different radio signal, so it’s possible to pick apart the contents of interstellar junk by examining a cloud’s frequency spectra. NASA, via the Ames Research Center, even maintains a radio-emission frequency database to aid in the tracking of polycyclic aromatic hydrocarbons, a form of molecule thought to contain much of the universe’s carbon stockpiles.

The branching carbon structure of isopropyle cyanide is of particular interest because it’s thought that this arrangement is a step on the way to the production of amino acids, the building blocks of proteins, and hence organic life. The discovery gives weight to the increasingly popular notion that life, or at least many of the key steps leading toward life, actually occurs off-planet.

alien-worldLife on Earth may have been well on its way while the planet was still just space dust waiting to come together into our rock-home. What’s more, the molecules discovered by the ALMA team probably aren’t alone.  As the authors, led by astronomer Arnaud Belloche, wrote:

[Isopropyle cyanide’s] detection therefore bodes well for the presence in the [interstellar medium] (ISM) of amino acids, for which such side-chain structure is a key characteristic… This detection suggests that branched carbon-chain molecules may be generally abundant in the [interstellar medium].

The discovery follows a general progression in recent years adding more and more life-ingredients to our picture of the ISM. A 2011 study revealed that complex organic matter should be created in large volumes from stars, while a 2012 report study found that conditions within the ISM are uniquely suited to the creation of increasingly complex molecules, “step[s] along the path toward amino acids and nucleotides, the raw materials of proteins and DNA, respectively.”

sugar-in-space-molecules_58724_990x742Also in 2012, astronomers working for ALMA found basic sugar molecules hanging out in the gas cloud around IRAS 16293-2422 – a young star located some 400 light-years from Earth. The particular form, glycoaldehyde, is thought to be a key component of the reaction behind the creation of DNA. Indeed, more and more, the universe is looking less and less like a harsh environment in which life must struggle to emerge, to a life factory.

News from Mars: Mysterious Martian Ball Found!

Mars_ballThe rocky surface of Mars has turned up some rather interestingly-shaped objects in the past. First there was the Martian rat, followed shortly thereafter by the Martian donut; and very recently, the Martian thighbone. And in this latest case, the Curiosity rover has spotted what appears to be a perfectly-round ball. Even more interesting is the fact that this sphere may be yet another indication of Mars’ watery past.

The rock ball was photographed on Sept. 11 – on Sol 746 of the rover’s mission on Mars – while Curiosity was exploring the Gale Crater. One of Curiosity’s cameras captured several images of the centimeter-wide ball as part of the stream of photographs was taking. The scientists working at the Mars Science Laboratory based at NASA’s Jet Propulsion Laboratory (JPL), immediately began to examine it for indications of what it could be.

mars-selfie-01-140501As Ian O’Neill of Discovery News, who spoke with NASA after the discovery, wrote:

According to MSL scientists based at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif., the ball isn’t as big as it looks — it’s approximately one centimeter wide. Their explanation is that it is most likely something known as a “concretion”… and they were created during sedimentary rock formation when Mars was abundant in liquid water many millions of years ago.

Curiosity has already found evidence of water at a dig site in Yellowknife Bay, which took place shortly after it landed in the Gale Crater two years ago. In addition, this is not the first time a Mars rover has found rocky spheres while examining the surface. In 2004, NASA’s Opportunity rover photographed a group of tiny balls made of a ferrous mineral called hematite. Opportunity photographed still more spheres, of a different composition, eight years later.

mars-blueberriesThe spheres likely formed through a process called “concretion”, where minerals precipitate within sedimentary rock, often into oval or spherical shapes. When the rock erodes due to wind or water, it leaves the balls of minerals behind and exposed. If in fact concretion caused the Mars spheres, then they would be evidence there was once water on the planet. However, some scientists believe the rock balls might be leftover from meteorites that broke up in the Martian atmosphere.

Curiosity is now at the base of Mount Sharp (Aeolis Mons) – The 5.6 km-high (3.5 mile) mountain in the center of Gale Crater – scientists are excited to commence the rover’s main science goal. This will consists of more drilling into layered rock and examining the powder so scientist can gain an idea about how habitable the Red Planet was throughout its ancient history, and whether or not it may have been able to support microbial life.

MarsCuriosityTrek_20140911_AMission managers will need to be careful as the rover has battered wheels from rougher terrain than expected. Because of this, the rover will slowly climb the slope of Mount Sharp driving backwards, so as to minimize the chance of any further damage. The Mars Reconnaissance Orbiter (MRO) will also be on hand to help, photographing the route from above to find the smoothest routes.

Despite the wear and tear that the little rover has experienced in its two years on the Martian surface, it has discovered some amazing things and NASA scientists anticipate that it will accomplish much more in the course of its operational history. And as it carried on with its mission to decode the secrets of Mars, we can expect it will find lots more interesting rocks – spherical, rat-shaped, ringed, femur-like, or otherwise.
