For the past two and a half years, the Curiosity Rover has been trekking across the surface of Mars, searching for clues as to what the planet looked like many eons ago. In addition to drilling, scanning, and occasionally taking breathtaking photos, it has also been monitoring data on the planet’s limited atmosphere, hoping to learn more about its composition and surface temperatures.

And according to the latest data obtained by the rover and processed by the Mars Science Laboratory (MSL), temperatures in the Gale Crater can reach a daytime high of -8 °C (17.6 °F). Meanwhile, here on Earth, cities in the northern US like Chicago and Buffalo were experiencing temperatures in the vicinity of -16 to -20 °C (2 to -4 °F). This means that, some parts of the United States are presently experiencing temperatures that are colder than on Mars!

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.

Buzz Aldrin: Let’s Go to Mars!

Apollo11_Aldrin1This past weekend was the 45th anniversary of the Moon Landing. To mark that occasion, NASA mounted the @ReliveApollo11 twitter campaign, where it recreated every moment of the historic mission by broadcasting updates in “real-time”. In addition to commemorating the greatest moment in space exploration, and one of the greatest moments in history, it also served to draw attention to new efforts that are underway.

Perhaps the greatest of these is one being led by Buzz Aldrin, a living-legend and an ambassador for current and future space missions. For decades now, Aldrin has been acting as a sort of elder statesman lobbying for the exploration of the cosmos. And most recently, he has come out in favor of a mission that is even grander and bolder than the one that saw him set foot on the Moon: putting people on Mars.

mars_spaceXmissionIt’s no secret that NASA has a manned mission planned for 2030. But with space exploration once again garnering the spotlight – thanks in no small part to commercial space companies like SpaceX and Virgin Galactic – Aldrin is pushing for something even more ambitious. Echoing ideas like Mars One, his plan calls for the colonization of Mars by astronauts who would never return to Earth.

To be sure, the spry 84 year-old has been rather busy in the past few years. After going through a very public divorce with his wife 0f 23 years in January of last year, he spent the past few months conducting a publicity blitz on behalf of the 45th anniversary of Apollo 11. In between all that, he has also made several appearances and done interviews in which he stressed the importance of the Martian colonization project.

Mars_OneA few months ago, Aldrin wrote an op-ed piece for Fast Company about innovation and the need for cooperation to make a new generation of space exploration a reality. During a more recent interview, which took place amidst the ongoing crisis in the Ukraine, he once again stressed the importance of cooperation between the United States, Russia, China, and their respective space programs.

As he told Fast Company in the interview:

I think that any historical migration of human beings to establish a permanent presence on another planet requires cooperation from the world together. That can’t be done by America competing with China… Just getting our people back up there is really expensive! We don’t compete but we can do other things close by with robots, which have improved tremendously over the past 45 years (since Apollo 11). You and I haven’t improved all that much, but robots have. We can work together with other nations in design, construction, and making habitats on both the near side and far side of Mars. Then when we eventually have designs, we’ll have the capacity to actually build them.

SLS_launchSimilarly, Aldrin took part in live Google Hangout with Space.com’s managing editor Tariq Malik and executive producer Dave Brody. This took place just eight days before the 25th anniversary of the Landing. During the broadcast, he discussed his experiences as an astronaut, the future of lunar exploration, future missions to Mars and beyond, and even took questions via chatwindow on Google+’s webpage.

At this juncture, its not clear how a colonization mission to Mars would be mounted. While Mars One is certainly interested in the concept, they (much like Inspiration Mars) do not have the necessary funding or all the technical know-how to make things a reality just yet. A possible solution to this could be a partnership program between NASA, the ESA, China, Russia, and other space agencies.

terraformingSuch ideas did inform Kim Stanley Robinson’s seminal novel Red Mars, where an international crew flew to the Red Planet and established the first human settlement that begins the terraforming process. But if international cooperation proves too difficult, perhaps a collaboration between commercial space agencies and federal ones could work. I can see it now: the Elon Musk Martian Dome; the Richard Branson Habitat; or the Gates colony…

With that in mind, I think we should all issue a prayer for international peace and cooperation! And in the meantime, be sure to check out the video of the Google Hangout below. And if you’re interested in reading up on Aldrin’s ideas for a mission to Mars, check out his book, Mission to Mars: My Vision for Space Exploration, which is was published by National Geographic and is available at Amazon or through his website.

Mission to Europa: NASA now Taking Suggestions

europa_moon_IoJupiter’s moon of Europa has been the subject of much speculation and intrigue ever since it was first discovered by Galileo in 1610. In addition to having visible sources of (frozen) surface water and a tenuous oxygen atmosphere, it is also believed to boast interior oceans that could very well support life. As evidence for this mounts, plans to explore Europa using robot landers, miners, submersibles, or even manned missions have been floated by various sources.

However, it was this past December when astronomers announced that water plumes erupting 161 kilometers (100 miles) high from the moon’s icy south pole that things really took a turn. It was the best evidence to date that Europa, heated internally by the powerful tidal forces generated by Jupiter’s gravity, has a deep subsurface ocean. In part because of this, NASA recently issued a Request for Information (RFI) to science and engineering communities for ideas for a mission to the enigmatic moon. Any ideas need to address fundamental questions about the subsurface ocean and the search for life beyond Earth.

europa-lander-2This is not the first time that NASA has toyed with the idea of investigating the Jovian moon for signs of life. Last summer, an article by NASA scientists was published in the peer-reviewed journal Astrobiology, which was entitled “Science Potential from a Europa Lander“. This article set out their research goals in more detail, and speculated how they might be practically achieved. At the time, the article indicated NASA’s ongoing interest, but this latest call for public participation shows that the idea is being taken more seriously.

This is positive news considering that NASA’s planned JIMO mission – Jupiter Icy Moon Orbiter, which was cancelled in 2005 – would be taking place by this time next year. Originally slated for launch between May and January of 2015/16, the mission involved sending a probe to Jupiter by 2021, which would then deploy landers to Callisto, Ganymede, Io and Europa for a series of 30 day studies. At the end of the mission in 2025, the vehicle would be parked in a stable orbit around Europa.

JIMO_Europa_Lander_MissionJohn Grunsfeld, associate administrator for the NASA Science Mission Directorate, had the following to say in a recent press release:

This is an opportunity to hear from those creative teams that have ideas on how we can achieve the most science at minimum cost… Europa is one of the most interesting sites in our solar system in the search for life beyond Earth. The drive to explore Europa has stimulated not only scientific interest but also the ingenuity of engineers and scientists with innovative concepts.

By opening the mission up to public input, it also appears that NASA is acknowledging the nature of space travel in the modern age. As has demonstrated with Chris Hadfield’s mission aboard the ISS, the Curiosity rover, as well as private ventures such as Mars One, Inspiration Mars, and Objective Europa  – the future of space exploration and scientific study will involve a degree of social media and public participation never before seen.

europa_reportThe RFI’s focus is for concepts for a mission that costs less than $1 billion, but will cover five key scientific objectives that are necessary to improve our understanding of this potentially habitable moon. Primarily, the mission will need to:

  1. Characterize the extent of the ocean and its relation to the deeper interior
  2. Characterize the ice shell and any subsurface water, including their heterogeneity, and the nature of surface-ice-ocean exchange
  3. Determine global surface, compositions and chemistry, especially as related to habitability
  4. Understand the formation of surface features, including sites of recent or current activity, identify and characterize candidate sites for future detailed exploration
  5. Understand Europa’s space environment and interaction with the magnetosphere.

Although Europa has been visited by spacecraft and imaged distantly by Hubble, more detailed research is necessary to understand the complexities of this moon and its potential for life. NASA’s Galileo spacecraft, launched in 1989 was the only mission to visit Europa, passing close by the moon fewer than a dozen times. Ergo, if we’re ever to determine conclusively whether or not life exists there, we’re going to have to put boots (robotic or human) onto the surface and start digging!

News From Mars: New Impact Crater and Landslides

Mars_impact_craterThe Mars Reconnaissance Orbiter, which has been in operation around Mars since March of 2006, has provided ongoing observation of the planet. Because of this, scientists and astronomers have been able to keep track of changes on the surface ever since. This new impact crater, which was formed by a recent meteor impact, is just the latest example.

The image was taken by the Orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera on Nov. 19, 2013. Since that time, NASA scientists have been working to enhance the image and rendering it in false color so the fresh crater appears.The resulting image shows the stunning 30-meter-wide crater with a rayed blast zone and far-flung secondary material surrounding.

Mars_Reconnaissance_OrbiterResearchers used HiRISE to examine this site because the orbiter’s Context Camera had revealed a change in appearance here between observations in July 2010 and May 2012, when the impact was thought to have occurred. After examining the impact site, scientists estimate the impact and resulting explosion threw debris as far as 15 kilometers in distance.

Before-and-after imaging that brackets appearance dates of fresh craters on Mars has indicated that impacts producing craters at least 12.8 feet (3.9 meters) in diameter occur at a rate exceeding 200 per year globally. But most of those are much smaller than this new one, and leave scars are as dramatic in appearance. This latest impact was definitely one for the history books.

Mars_dunesSpeaking of dramatic, these recent releases from the HiRISE laboratory captured some truly magnificent activity, which included a series of avalanches and defrosting dunes on the surface. Snow, dust and wind are combining to make the incredible images that were captured. The raw images appear in black and white (as the snowy dunes pictured above).

The colorized versions, as show below, indicate the presence of snow, ice and red surface dust. These latest pictures, perhaps more than any previous, illustrate the awe and wonder the Red Planet holds. And as humanity’s contact and involvement with the planet and continues, they remind us that nothing from that world is to be taken for granted.

mars_avalanche mars_avalanche1 mars_avalanche2 mars_avalanche3And as we get closer to 2030, when a manned mission is scheduled to take place – not to mention private missions that aim to put colonists there by 2023 – chance encounters with the surface like this are certain to inspire excitement and anticipation. Right now, these events and surface features are being watched from above or by rovers on the surface.

But someday soon, people will be standing on the surface and looking upon it with their own eyes. Their feet will be crushing into red sand, romping through Martian snow and ice, and standing in the middle of craters and looking up at Olympus Mons. What will they be thinking as they do it? We can only wonder and hope that we’ll be able to share it with them…

News From Space: Mars Needs Money!

Mars_OneRemember Mars One, the Netherlands-based nonprofit that began seeking recruits for a one-way trip to the Red Planet during the summer of 2012? Well, it turns out the company is looking to take the next step towards its goal of establishing a human settlement on Mars by 2023. Basically, they are looking to raise the funds to get the ball rolling on the eventual manned mission.

Towards this end, they have started a crowdfunding campaign through Indiegogo – and in partnership with Lockheed Martin – to raise the money for some concept studies, which will test the lander and a satellite that will conduct a demonstration mission in just four years time. The lander is based on Lockheed’s design for the NASA lander successfully used on Mars in 2007 (pictured below).

Mars-One-2018-LanderTheir campaign is seeking to raise $400,000, which will cover the costs of the concept studies, and is a mere drop in the bucket compared to the $6 billion the team estimates will be necessary to get humans to Mars. However, most of that money is expected to come from media broadcasting rights as citizen astronauts are selected and, if all goes as planned, start living on the Martian surface.

As has been stated many times over, Mars One is an evolving idea that seeks to make something historic happen. A future, larger crowdfunding campaign will allow universities to compete to send a full experiment to Mars on the 2018 mission, which will be unmanned. Mars One hopes to send four human colonists to the planet by 2025, selected from a pool of more than 200,000 people who have already applied.

mars_one1And as Hans Lansdorp, CEO of Mars One recently said, this crowdfunding campaign is important to the team to get more people involved. Not only does the project require public interest and participation in order for it to become a reality, Lansdorp and his colleagues also want it to be as international and inclusive as possible:

We really see this as a break with the history of space exploration, and especially Mars exploration, because in this mission anyone can participate in some way… For the U.S., Mars exploration is pretty common. But all of Asia has never sent an experiment to Mars. Now, suddenly we allow anyone, everywhere in the world, to send something to Mars. That’s a complete break with Mars exploration in the past.

Naturally, there are plenty of issues that need to be worked out before anything real can happen, and plenty of naysayers who emphasize the stumbling blocks in sending a manned mission to Mars. These include, but are not restricted to, radiation, microgravity, technological limitations, and the sheer amount of time involved.

mars_one2Despite all that, Lansdorp and the Mars One team remain committed and dedicated to their goal, and have been taking on all challengers with their usual combination of optimism and entrepreneurial spirit. And they firmly believe that given time, all of these hurdles will be negotiable. What’s more, they’ve convinced more than a few critics of the validity of the mission:

If we have some time to talk to people and explain the details of our plan, and as long as they’re commenting on their own field of expertise, I’ve never met someone who could not be convinced that this is possible. It will be very difficult of course–there are thousands of hurdles on the road between now and landing on Mars–but there are no hurdles that we can identify that we cannot take.

As of the penning of this article, the Mars One campaign has been open since December 10th and has raised $209,677 of its $400,000 goal, with 18 more days to go. And there are certainly no shortage of volunteers, as the company is currently processing applications from 150,000 people. So even if it can’t happen by the proposed date, it is clear that they have grabbed the world’s attention.

And in the meantime, enjoy these videos of the proposed Mars One lander design (which will take place in the 2018 demo mission) and the company’s latest promotional video:

News from Space: Curiosity Finds Water!

curiosity_drillsGood news (and bad) from the Red Planet! According to NASA, an examination of the fine-grained soil particles extracted by Curiosity, scientists have concluded that roughly 2 percent of Martian surface soil is made up of water. Though they did not find any traces of organic particles, this latest find confirms that water not only used to exist on the surface of the planet, but can still be found within.

These results bode well for future manned missions to Mars, wherein astronauts could mine the soil for water and study it to advance their understanding of Mars’ history. The findings, which were published today in the journal Science are part of a five-paper segment that began back in August of 2012 and is dedicated to Curiosity’s ongoing mission.

curiosity_drilling2Laurie Leshin, dean of the School Science at Rensselaer Polytechnic Institute and lead author of the paper, said in a NASA press release:

One of the most exciting results from this very first solid sample ingested by Curiosity is the high percentage of water in the soil.

These tests were conducted using the rover’s Sample Analysis at Mars (SAM), a collection of instruments that includes a gas chromatograph, a mass spectrometer, and a tunable laser spectrometer. The first soil samples were collected back in February when the rover used its drill tool for the first time and created a series of holes that were a little over 6 centimeters (2.5 inches) deep and collected the fine dust that resulted.

SAM_NASAOnce placed into the SAM assembly, the samples were heated to 835 degrees Celsius (1,535 degrees Fahrenheit). The gases that were released – which included significant portions of carbon dioxide, oxygen, and sulfur compounds – were then analyzed. The Mars Science Laboratory (MSL) also noticed that quantities of gaseous carbonite were found, which would suggests the presence of water in the Martian soil.

These positive findings were quite welcome, especially in light of the disheartening news last week that Curiosity has yet to crack the methane mystery. Back in 2003, scientists observed methane plumes coming from the planet, a strong indicator of microbial life, which sent scientific and professional interest in finding life on the red planet soaring.

Since that time, no traces of methane have been found, and it was hoped that Curiosity would finally locate it. However, the lack of methane thus far indicates that the rover has little chance of finding existing microbial life on the planet. But the existence of water in such great quantities in the surface soil brings scientists one step closer to piecing together the planet’s past potential for harboring life.

Curiosity_drillingsPaul Mahaffy, a lead investigator for SAM at NASA’s Goddard Space Flight Center, had this to say:

This work not only demonstrates that SAM is working beautifully on Mars, but also shows how SAM fits into Curiosity’s powerful and comprehensive suite of scientific instruments… By combining analyses of water and other volatiles from SAM with mineralogical, chemical, and geological data from Curiosity’s other instruments, we have the most comprehensive information ever obtained on Martian surface fines. These data greatly advance our understanding surface processes and the action of water on Mars.

Given the renewed interest of late in manned missions to Mars – from nonprofit organizations like Mars One, privatized transportation companies like SpaceX, and the unofficial plans to mount a manned mission to Mars by 2030 by NASA – these findings are reassuring. In addition to providing fuel for hydrogen fuel cells for a return craft, subsurface water will be a boon for settlers and terraformers down the road.

mars-one-brian-versteegLeshin confirmed a cubic foot of soil, as opposed to the tiny sample Curiosity analyzed, could yield nearly 2 pints of condensation when heated. So volunteers who are planning on signing up with Mars One, pack your buckets and stoves and be prepared to do a lot of condensing! And perhaps we can expect “moisture farms” to become the norm on a colonized Mars of the future.

News From Space: Manned Europa Mission!

europa-landerWith so much attention focused on Mars in recent years, the other planets of the Solar System have a hard time getting noticed. But lately, Europa has found itself the subject of some interest. In addition to NASA proposing to send a lander there in the near future, a private space organization is thinking of mounting a manned mission to the Jovian moon in search of knowledge and extra-terrestrial life.

This organization is known as Objective Europa, a group made up of  volunteer scientists, conceptual artists, and social-media experts. At the moment, they exist only on the internet. But with time and financial backing, they hope to form a volunteer corps of settlers that would make a one-way trip to Europa and settle the planet while they researched it.

europa-lander-2Inspired by the recent missions to Mars, Objective Europa also believes a mission to this moon would be worthwhile since it is a far better candidate for extra-terrestrial life. Mars, though it is thought to have once hosted life, is a barren and dry world in its present state. Though many are holding out for the discovery of organic particles in the near future, the likelihood of finding any complex organisms larger than a microbe remains extremely low.

Not surprisingly, their group has attracted some big-name celebrities. This includes Kristian von Bengtson, a Danish architect and co-founder of Copenhagen Suborbitals, a nonprofit focused on launching humans into space. Then there’s Michele Faragalli, a rover mobility specialist for a NASA private contractor. Scientist and diver Pierre-Yves Cousteau, son of legendary explorer Jacques Cousteau, is also on the team as an ambassador for the group.

europa_reportCurrently, the group is in Phase 1 of their plan, which is geared towards the gathering of ideas. Towards this end, they have opened up a variety of research topics for discussion on their website. These include investigating the feasibility of a manned mission versus a robotic mission, launch vehicle studies, and cost analysis.Future phases would involve raising funds, and prototyping and testing technology.

What’s more, while they have not yet stated outright how they plan to fund the mission, it seems likely at this point that crowdfunding and sponsorship will come into play. As the goal statement reads on their site:

“Our purpose is to establish the foundation for and carry out a crewed mission to Jovian ice moon Europa through international crowd-research and participation.”

mars-one-brian-versteegIf this is beginning to sound a little bit like Mars One – a similar space organization looking to send volunteers to Mars – then chances are you’ve been paying attention! In terms of their purpose, objectives, and the fact that the trips they are planning would be a one-way, the two organizations are very similar. But even more interesting is what these and other space organizations like them represent.

In an age when private space travel and exploration are beginning in earnest, crowdfunded, volunteer groups are emerging with the common goal of making things happen ahead of anyone else’s schedule. Whereas space was once the exclusive province of government-sanctioned and funded agencies, now the public is stepping in to assume a measure of control.

And thanks to new media and communications, the money, talent, and energy needed are all available. It’s just a matter of bringing them all together!

100,000 People Want to Go to Mars, And Not Come Back

MarsOneEver since they announced their plan to establish a colony on Mars by 2022, Mars One has been flooded by applicants eager to set foot on a new planet and make it their home. In fact, according to a recent story by CNN Tech, over 100,000 people have volunteered for the mission, knowing full well that it would be a one-way trip and their stay on the Red Planet would be permanent.

Anyone who is 18 years of age or older can apply, and the fee runs anywhere from $15 to $38, depending on your nationality and the gross domestic product of your country. Ultimately, only 40 people will be selected this year, and only two couples will be sent ahead with the first mission. This mission is slated to leave by September of 2022 and land on Mars by April of 2023, with another group of four to be sent two years later.

There is also a very large number of people who are still working on their profile, so either they have decided not to pay the application fee, or they are still making their video or they’re still filling out the questionnaire or their resume. So the people that you can see online are only the ones that have finished and who have set their profiles as public.

In terms of what the selectees will do once the project is up and running, the website offers a basic rundown. First, the volunteer astronauts will undergo a required eight-year training in a secluded location, where they will learn how to repair habitat structures, grow vegetables in confined spaces and address “both routine and serious medical issues such as dental upkeep, muscle tears and bone fractures.”

After eight missions, more than 44,000 pounds of supplies and 40 people will have arrived and the capsules themselves will be formed into the settler’s habitat.

Two things Earth won’t be sending is water and oxygen, since the settlers will be manufacturing these themselves. According to Lansdrop, these will be manufactured on Mars:

We will evaporate it and condense it back into its liquid state. From the water we can make hydrogen and oxygen, and we will use the oxygen for a breathing atmosphere inside the habitat. This will be prepared by the rovers autonomously before the humans arrive.

In addition, there are experts who say that the risks are too high given the distance and exposure to radiation involved. A round-trip journey to Mars could expose astronauts to the maximum amount of radiation allowed in a career under current NASA standards. While Mars One does not negate this issue, they have yet to indicate how they intend to keep their astronauts shielded from the harmful cosmic rays.

What’s more, Lansdrop has said repeatedly that the project will be funded by sponsors and media that will pay for broadcasting rights of shows and movies documenting everything from the astronauts’ training on Earth to their deployment and colonization of Mars.

Basically, they intend for the entire process to be a worldwide media event, a massive reality TV show, with the necessary advances and funding worked out as time goes on. Right now, all they are looking for is volunteers so that corporate and media sponsors understand just how serious this is and that the willingness to go is there. No telling if that will be enough, but it is a start.

The Inspiration Mars Foundation is another such private venture, which is seeking to send a couple on a 501-day, round-trip journey aboard a space craft that will take then to Mars and back in 2018 without ever touching down on the surface.

Here too, the issue of funding, the technology involved, and the problem of radiation shielding are all being considered and ironed out in an ongoing manner, with some rather interesting possibilities being considered (such as using human feces and waste plumbing to shield the astronauts from radiation!)

spacecraft_marsUltimately, it seems that certain private ventures are not willing to wait for NASA’s planned 2030 excursion to Mars before general settlement and terraforming can begin. And though it may prove unfeasibly by the time frames being proposed, the excitement and desire to make things happen sooner than projected are understandable.

And as Lansdorp explains, much of the project has to do with telling a story, perhaps the greatest ever told:

What we want to do is tell the story to the world. When humans go to Mars, when they settle on Mars and build a new Earth, a new planet. This is one of the most exciting things that ever happened, and we want to share the story with the entire world.
