The Mars One organization released this announcement on Tuesday:78,000 sign up for one-way mission to MarsAmersfoort, 7th May 2013 – Just two weeks into the nineteen week application period, more than seventy-eight thousand people have applied to the Mars One astronaut selection program in the hope of becoming a Mars settler in 2023.
Mars One has received applications from over 120 countries. Most applications come from USA (17324), followed by China (10241), United Kingdom (3581), Russia, Mexico, Brazil, Canada, Colombia, Argentina and India.
Bas Lansdorp, Mars One Co-Founder and CEO said: “With seventy-eight thousand applications in two weeks, this is turning out to be the most desired job in history. These numbers put us right on track for our goal of half a million applicants.”
“Mars One is a mission representing all humanity and its true spirit will be justified only if people from the entire world are represented. I’m proud that this is exactly what we see happening,” he said.
As part of the application every applicant is required to explain his/her motivation behind their decision go to Mars in an one minute video. Many applicants are choosing to publish this video on the Mars One website. These are openly accessible on applicants.mars-one.com.
“Applicants we have received come from a very wide range of personalities, professions and ages. This is significant because what we are looking for is not restricted to a particular background. From Round 1 we will take forward the most committed, creative, resilient and motivated applicants,” said Dr. Norbert Kraft, Mars One Chief Medical Officer.
Mars One will continue to receive online applications until August 31st 2013. From all the applicants in Round 1, regional reviewers will select around 50-100 candidates for Round 2 in each of the 300 geographic regions in the world that Mars One has identified.
Four rounds make the selection process, which will come to an end in 2015; Mars One will then employ 28-40 candidates, who will train for around 7 years. Finally an audience vote will elect one of groups in training to be the envoys of humanity to Mars.
I’m not surprised most of the applicants are from the U.S., but the number of applicants from China does a little bit.
Maybe it shouldn’t though, the Chinese maybe looking for lebensraum ( elbow room ), what with over a billion people and all.
Mars might be an appealing bit of real estate to them.
From Centauri Dreams:
Existential risks, as discussed here yesterday, seem to be all around us, from the dangers of large impactors to technologies running out of control and super-volcanoes that can cripple our civilization. We humans tend to defer thinking on large-scale risks while tightly focusing on personal risk. Even the recent events near Chelyabinsk, while highlighting the potential danger of falling objects, also produced a lot of fatalistic commentary, on the lines of ‘if it’s going to happen, there’s nothing we can do about it.’ Some media outlets did better than others with this.
Risk to individuals is understandably more vivid. When Apollo 8 left Earth orbit for the Moon in 1968, the sense of danger was palpable. After all, these astronauts were leaving an orbital regime that we were beginning to understand and were, by the hour, widening the distance between themselves and our planet. But even Apollo 8 operated within a sequenced framework of events. Through Mercury to Gemini and Apollo, we were building technologies one step at a time that all led to a common goal. No one denied the dangers faced by every crew that eventually went to the Moon, but technologies were being tested and refined as the missions continued.
Inspiration Mars is proposing something that on balance feels different. As described in yesterday’s news conference (see Millionaire plans to send couple to Mars in 2018. Is that realistic? for more), the mission would be a flyby, using a free return trajectory rather than braking into Martian orbit. The trip would last 501 days and would be undertaken by a man and a woman, probably a middle-aged married couple. Jonathan Clark, formerly of NASA and now chief medical officer for Inspiration Mars, addresses the question of risk head-on: “The real issue here is understanding the risk in an informed capacity – the crew would understand that, the team supporting them would understand that.” Multi-millionaire Dennis Tito, a one-time space tourist who heads up Inspiration Mars, says the mission will launch in 2018.
Image: A manned Mars flyby may just be doable. But is the 2018 date pushing us too hard? Image credit: NASA/JPL.
We’ll hear still more about all this when the results of a mission-feasibility study are presented next weekend at the 2013 IEEE Aerospace Conference in Montana. Given the questions raised by pushing a schedule this tightly, there will be much to consider. Do we have time to create a reliable spacecraft that can offer not only 600 cubic feet of living space but another 600 for cargo, presumably a SpaceX Dragon capsule mated to a Bigelow inflatable module? Are we ready to expose a crew to interplanetary radiation hazards without further experience with the needed shielding strategies? And what of the heat shield and its ability to protect the crew during high-speed re-entry at velocities in the range of 50,000 kilometers per hour?
For that matter, what about Falcon Heavy, the launch vehicle discussed in the feasibility analysis Inspiration Mars has produced for the conference? This is a rocket that has yet to fly.
No, this doesn’t feel much like Apollo 8. It really feels closer to the early days of aviation, when attention converged on crossing the Atlantic non-stop and pilots like Rene Fonck, Richard Byrd, Charles Nungesser and Charles Lindbergh queued up for the attempt. As with Inspiration Mars, these were privately funded attempts, in this case designed to win the Orteig Prize ($25,000), though for the pilots involved it was the accomplishment more than the paycheck that mattered. Given the problems of engine reliability at the time, it took a breakthrough technology — the Wright J-5C Whirlwind engine — to get Lindbergh and subsequent flights across.
Inspiration Mars is looking to sell media rights and sponsorships as part of the fund-raising package for the upcoming mission, which is already being heavily backed by Tito. I’m wondering if there is a breakthrough technology equivalent to the J-5C to help this mission along, because everything I read about it makes it appear suicidal. The 2018 date is forced by a favorable alignment between Mars and the Earth that will not recur until 2031, so the haste is understandable. The idea is just the kind of daring, improbable stunt that fires the imagination and forces sudden changes in perspective, and of course I wish it well. But count me a serious skeptic on the question of whether this mission will be ready to fly on the appointed date.
And if it’s not? I like the realism in the concluding remarks of the feasibility study:
A manned Mars free-return mission is a useful precursor mission to other planned Mars missions. It will develop and demonstrate many critical technologies and capabilities needed for manned Mars orbit and landing missions. The technology and other capabilities needed for this mission are needed for any future manned Mars missions. Investments in pursuing this development now would not be wasted even if this mission were to miss its launch date.
Exactly so, and there would be much development in the interim. The study goes on:
Although the next opportunity after this mission wouldn’t be for about another 13 years, any subsequent manned Mars mission would benefit from the ECLSS [Environmental Control and Life Support System], TPS [Thermal Protection System], and other preparation done for this mission. In fact, often by developing technology early lessons are learned that can reduce overall program costs. Working on this mission will also be a means to train the skilled workforce needed for the future manned Mars missions.
These are all good reasons for proceeding, leaving the 2018 date as a high-risk, long-shot option. While Inspiration Mars talks to potential partners in the aerospace industry and moves ahead with an eye on adapting near-Earth technologies for the mission, a whiff of the old space race is in the air. “If we don’t fly in 2018, the next low-hanging fruit is in ’31. We’d better have our crew trained to recognize other flags,” Tito is saying. “They’re going to be out there.”
In 1968, faced with a deadline within the decade, NASA had to make a decision on risk that was monumental — Dennis Tito reminded us at the news conference that Apollo 8 came only a year after the first test launch of the Saturn 5. Can 2018 become as tangible a deadline as 1970 was for a nation obsessed with a Moon landing before that year? If so, the technologies just might be ready, and someone is going to have to make a white-knuckle decision about the lives of two astronauts. If Inspiration Mars can get us to that point, that decision won’t come easy, but whoever makes it may want to keep the words of Seneca in mind: “It is not because things are difficult that we dare not venture. It is because we dare not venture that they are difficult.”
There are a lot of nay-sayers out yonder decrying Tito’s idea as suicidal and a waste of money. But as recently as a couple of months ago questionnaires were sent out asking for volunteers to sign up for a one way trip to Mars (Mars One), even if there’s a better than even chance of dying at any moment of it.
The results were astounding.
Tito’s idea of sending an older married couple is nothing short of public opinion genius and if successful, could be the format of any future Mars colonization efforts.
Not to mention the technologies needed for the crossing.
From Centauri Dreams:
Tim Folger and Les Johnson (NASA MSFC) stood last summer in front of a nuclear rocket at Marshall Space Flight Center in Huntsville, Alabama. Johnson’s work in advanced propulsion concepts is well known to Centauri Dreams readers, but what he was talking to Folger about in an article for National Geographic was an older technology. NERVA, once conceived as part of the propulsion package that would send astronauts to Mars, had in its day the mantle of the next logical step beyond chemical propulsion. A snip from the story:
Johnson looks wistfully at the 40,000-pound engine in front of us… “If we’re going to send people to Mars, this should be considered again,” Johnson says. “You would only need half the propellant of a conventional rocket.” NASA is now designing a conventional rocket to replace the Saturn V, which was retired in 1973, not long after the last manned moon landing. It hasn’t decided where the new rocket will go. The NERVA project ended in 1973 too, without a flight test. Since then, during the space shuttle era, humans haven’t ventured more than 400 miles from Earth.
I’m looking forward to getting back to Huntsville and seeing Les, as well as a number of other friends in the interstellar community, at the 2nd Tennessee Valley Interstellar Workshop, coming up this February, where it may be that NERVA will have a place in the discussion of how we go about building a system-spanning civilization. You’ll want to give Folger’s article a look for comments not only from Les but Freeman Dyson and Andreas Tziolas (from the Icarus team), as well as Elon Musk, the 100 Year Starship’s Mae Jemison, and NASA’s Mason Peck.
Image: NERVA nuclear rocket being tested. (Smithsonian Institution Photo No. 75-13750).
In fact, there are a number of issues presented here that I’ll want to get back to later, but I can’t cover the rest of the story today. I’m all but out the door for a brief but intense period of Tau Zero work that will leave me no time to keep up regular posts here or even to moderate comments. More about this later, and more about Folger’s essay as well, and please bear with me through the temporary slowdown. Things should get back to normal by mid-day Thursday.
Speaking of NERVA, though, I’ll leave you with an interesting petition Gregory Benford alerted me to with regard to the development of nuclear thermal rockets, one that calls for an effort to:
Harness the full intellectual and industrial strength of our universities, national laboratories and private enterprise to rapidly develop and deploy a nuclear thermal rocket (NTR) adaptable to both manned and un-manned space missions. A NTR (which would only operate in outer space) will jump-start our manned space exploration program by reducing inner solar system flight times from months to weeks. This is not new technology; NTRs were tested in the 1960s (President Kennedy was a guest at one test). The physics and engineering are sound. In addition to inspiring young Americans to careers in science, technology, engineering and mathematics, a working NTR will herald a speedy and economical expansion of the human presence in the cosmos.
Going significantly beyond the Moon demands advances in propulsion of the kind that nuclear thermal rockets can deliver. Getting NERVA concepts out of mothballs and updating them with modern materials are necessary steps as we push out into the Solar System.
Going to Mars does require a serious upgrade to nuclear rocket technology, but somehow I don’t think the taxpaying public will go for funding research by the government, especially in this era of deficits and flat budgets.
This kind of research will probably be taken up by the private sector, perhaps with some seed money from the government, but only if there’s an economic need to exploit the resources of the Solar System, including planetary bodies like Mars.
It would be nice for such research like NERVA could be funded for the future of Mankind, but unfortunately that’s not how the world is set up now.
One can only hope.
Stanford researchers in collaboration with NASA JPL and MIT have designed a robotic platform that involves a mother spacecraft deploying one or several spiked, roughly spherical rovers to the Martian moon Phobos.
Measuring about half a meter wide, each rover would hop, tumble and bound across the cratered, lopsided moon, relaying information about its origins, as well as its soil and other surface materials.
Developed by Marco Pavone, an assistant professor in Stanford’s Department of Aeronautics and Astronautics, the Phobos Surveyor, a coffee-table-sized vehicle flanked by two umbrella-shaped solar panels, would orbit around Phobos throughout the mission. The researchers have already constructed a prototype.
The Surveyor would release only one hedgehog at a time. Together, the mothership and hedgehogs would work together to determine the hedgehog’s position and orientation. Using this information, they would map a trajectory, which the mother craft would then command the hedgehog to travel.
In turn, the spiky explorers would relay scientific measurements back to the Phobos Surveyor, which would forward the data to researchers on Earth. Based on their analysis of the data, the scientists would direct the mothership to the next hedgehog deployment site.
An entire mission would last two to three years. Just flying to Phobos would take the Surveyor about two years. Then the initial reconnaissance phase, during which the Surveyor would map the terrain, would last a few months. The mothership would release each of the five or six hedgehogs several days apart, allowing scientists enough time to decide where to release the next hedgehog.
For many decisions, Pavone’s system renders human control unnecessary. “It’s the next level of autonomy in space,” he said.
The synergy between the Phobos Surveyor and the hedgehogs would also be reflected in their sharing of scientific roles. The Surveyor would take large-scale measurements, while the hedgehogs would gather more detailed data. For example, the Surveyor might use a gamma ray or neutron detector to measure the concentration of various chemical elements and compounds on the surface, while the hedgehogs might use microscopes to measure the fine crevices and fissures lining the terrain.
Although scientists could use the platform to explore any of the solar system’s smaller members, including comets and asteroids, Pavone has designed it with the Martian moon Phobos in mind.
An analysis of Phobos’ soil composition could uncover clues about the moon’s origin. Scientists have yet to agree on whether Phobos is an asteroid captured by the gravity of Mars or a piece of Mars that an asteroid impact flung into orbit. This could have deep implications for our current understanding of the origin and evolution of the solar system, Pavone said.
To confirm Phobos’ origins, Pavone’s group plans to deploy most of the hybrids near Stickney Crater. Besides providing a gravity “sweet spot” where the mother craft can stably hover between Mars and Phobos, the crater also exposes the moon’s inner layers.
A human mission to Mars presents hefty challenges, mainly associated with the planet’s high gravity, which heightens the risk of crashing during takeoffs and landings. The large amounts of fuel needed to overcome Mars’ strong pull during takeoffs could also make missions prohibitively expensive.
But Phobos’ gravity is a thousand times weaker than on Mars. If Phobos did indeed originate from the red planet, scientists could study Mars without the dangers and costs associated with its high gravity simply by sending astronauts to Phobos. They could study the moon itself or use it as a base station to operate a robot located on Mars. The moon could also serve as a site to test technologies for potential use in a human mission to the planet.
“It’s a piece of technology that’s needed before any more expensive type of exploration is considered,” Pavone said of the spacecraft-rover hybrid. “Before sampling we need to know where to land. We need to deploy rovers to acquire info about the surface.”
These probes could be precursors to a sample return mission. A promising area to dig determined beforehand would cut down on cost and wear and tear.
But these rovers could be used on their own for private industry, such as Google Maps in order to give ( and sell ) accurate virtual reality tours to Millenials who wish to sit in their livingrooms and explore Mars safely.
A true pre-Singularity technology.
From New Scientist:
You needn’t fry on Mars. Readings from NASA’s Curiosity rover suggest radiation levels on the Red Planet are about the same as those in low Earth orbit, where astronauts hang out for months on the International Space Station. A Mars visit would still be dangerous though, due to the years-long return trip.
Unlike Earth, Mars has no magnetosphere shielding it from solar and galactic radiation. But it does have a thin atmosphere, and readings from two of Curiosity’s instruments suggest this provides some protection.
“This is the first ever measurement of the radiation environment on any planet other than Earth,” Curiosity team member Don Hassler said at a press briefing on 15 November. “Astronauts can live in this environment.”
The rover’s weather station recorded evidence of what is known as a thermal tide on Mars. Sunlight heats the planet’s atmosphere on the side facing the sun, causing it to expand upwards and triggering a decrease in air pressure. But things chill quickly on the other side, so that the atmosphere deflates and becomes denser.
As Mars rotates, the bulge of heated air travels with the “day” side from east to west. Curiosity feels this effect as changes in air pressure over the course of a Martian day, rover scientist Claire Newman of Ashima Research in California said during the briefing.
At the same time, the rover’s radiation monitor saw daily dips in charged particles that match the increases in air pressure that come with a denser atmosphere. “The atmosphere is acting as a shield to radiation,” Hassler said.
The scientists were not ready to put numbers to the daily radiation dose people would experience on Mars. But the overall levels are lower than those the spacecraft carrying Curiosity recorded during its interplanetary flight, and about what astronauts see on the ISS.
“It’s roughly what we were expecting,” astrobiologist Lewis Dartnell of University College London told New Scientist.
The biggest threat to Mars voyagers would be the cumulative radiation exposure during the long trip. NASA estimates that a return human mission to Mars would take three years. During that time astronauts might receive more than seven times the radiation dose they get during six months on the ISS.
Building up radiation exposure increases the risk of developing various cancers, so NASA has set limits on how much total radiation astronauts can experience over the course of their careers. Figuring out the exact risk on Mars is crucial to understanding the total dose a human mission would face and whether it is within safe limits, Hassler said.
Solar flares would also be a problem. On Earth these eruptions of charged particles from the sun are largely deflected by the magnetosphere. But Mars enjoys no such protection, and since Curiosity has yet to see a flare, it is unclear how much shielding the thin atmosphere would provide. ‘
Dartnell suggests that a base or colony on Mars could be built underground to avoid surface radiation. Or, with enough advance warning, astronauts could retreat to protective shelters during a flare. But is all that trouble worth it just to send humans where robots already thrive?
“An astronaut or geologist that’s trained in science that has a brain and a pair of hands and pair of eyes with a rock hammer can do a lot more on the surface on Mars before breakfast than a robot can do in weeks,” says Dartnell.
Well, I guess I stand corrected on my blog post yesterday about human destroying radiation on the Martian surface yesterday!
This is a good thing, if one is a supporter of human based spaceflight and colonization, but one must remember the financial cost of such an endeavor, despite of the discovery that the Martian atmosphere can turn away radiation to a manageable level.
But perhaps Elon Musk can get his initial wish of landing an automated green-house on Mars? That would would be a good test to see if organics can grow there with few harmful mutations?

NASA’s plucky Mars Exploration Rover Opportunity has thrived for nearly a decade traversing the plains of Meridiani Planum despite the continuous bombardment of sterilizing cosmic and solar radiation from charged particles thanks to her radiation hardened innards. How about humans? What fate awaits them on a bold and likely year’s long expedition to the endlessly extreme and drastically harsh environment on the surface of the radiation drenched Red Planet – if one ever gets off the ground here on Earth? How much shielding would people need? Answering these questions is one of the key quests ahead for NASA’s SUV sized Curiosity Mars rover – now 100 Sols, or Martian days, into her 2 year long primary mission phase. Preliminary data looks promising. Curiosity survived the 8 month interplanetary journey and the unprecedented sky crane rocket powered descent maneuver to touch down safely inside Gale Crater beside the towering layered foothills of 3 mi. (5.5 km) high Mount Sharp on Aug. 6, 2012. Now she is tasked with assessing whether Mars and Gale Crater ever offered a habitable environment for microbial life forms – past or present. Characterizing the naturally occurring radiation levels stemming from galactic cosmic rays and the sun will address the habitability question for both microbes and astronauts. Radiation can destroy near-surface organic molecules.

Researchers are using Curiosity’s state-of-the-art Radiation Assessment Detector (RAD) instrument to monitor high-energy radiation on a daily basis and help determine the potential for real life health risks posed to future human explorers on the Martian surface. “The atmosphere provides a level of shielding, and so charged-particle radiation is less when the atmosphere is thicker,” said RAD Principal Investigator Don Hassler of the Southwest Research Institute in Boulder, Colo. See the data graphs. “Absolutely, the astronauts can live in this environment. It’s not so different from what astronauts might experience on the International Space Station. The real question is if you add up the total contribution to the astronaut’s total dose on a Mars mission can you stay within your career limits as you accumulate those numbers. Over time we will get those numbers,” Hassler explained. The initial RAD data from the first two months on the surface was revealed at a media briefing for reporters on Thursday, Nov. 15 and shows that radiation is somewhat lower on Mars surface compared to the space environment due to shielding from the thin Martian atmosphere. RAD hasn’t detected any large solar flares yet from the surface. “That will be very important,” said Hassler. “If there was a massive solar flare that could have an acute effect which could cause vomiting and potentially jeopardize the mission of a spacesuited astronaut.” “Overall, Mars’ atmosphere reduces the radiation dose compared to what we saw during the cruise to Mars by a factor of about two.” RAD was operating and already taking radiation measurements during the spacecraft’s interplanetary cruise to compare with the new data points now being collected on the floor of Gale Crater.

Mars atmospheric pressure is a bit less than 1% of Earth’s. It varies somewhat in relation to atmospheric cycles dependent on temperature and the freeze-thaw cycle of the polar ice caps and the resulting daily thermal tides. “We see a daily variation in the radiation dose measured on the surface which is anti-correlated with the pressure of the atmosphere. Mars atmosphere is acting as a shield for the radiation. As the atmosphere gets thicker that provides more of a shield. Therefore we see a dip in the radiation dose by about 3 to 5%, every day,” said Hassler. There are also seasonal changes in radiation levels as Mars moves through space. The RAD team is still refining the radiation data points. “There’s calibrations and characterizations that we’re finalizing to get those numbers precise. We’re working on that. And we’re hoping to release that at the AGU [American Geophysical Union] meeting in December.”

This article epitomizes the battle between the sending humans to explore space and the artificial life-form/machine crowds.
I can truly understand the human exploration groups – they are the folks I grew up with during the Gemini/Apollo/Moon-landing eras and I will forever regard those folks as heroes and pioneers.
But as a late middle-aged adult who has followed the Space Age for the past 50 years I see the writing on the wall – economics are determining the course of spaceflight into the Solar System and Universe. And machine explorers are definitely more economical than human ones, especially in the foreseeable future.
I remain hopeful however that individuals like James Cameron and Elon Musk will find economical ways to colonize Mars and eventually nearby planets within 4 – 6 light-years.
Hey, if the Marianas Trench can be explored by folks like Cameron, so can Mars and Alpha Centauri Bb!
From Wired Science:
When a man tells you about the time he planned to put a vegetable garden on Mars, you worry about his mental state. But if that same man has since launched multiple rockets that are actually capable of reaching Mars—sending them into orbit, Bond-style, from a tiny island in the Pacific—you need to find another diagnosis. That’s the thing about extreme entrepreneurialism: There’s a fine line between madness and genius, and you need a little bit of both to really change the world.
All entrepreneurs have an aptitude for risk, but more important than that is their capacity for self-delusion. Indeed, psychological investigations have found that entrepreneurs aren’t more risk-tolerant than non-entrepreneurs. They just have an extraordinary ability to believe in their own visions, so much so that they think what they’re embarking on isn’t really that risky. They’re wrong, of course, but without the ability to be so wrong—to willfully ignore all those naysayers and all that evidence to the contrary—no one would possess the necessary audacity to start something radically new.
I have never met an entrepreneur who fits this model more than Elon Musk. All of the entrepreneurs I admire most—Musk, Jeff Bezos, Reed Hastings, Jack Dorsey, Sergey Brin and Larry Page, Bill Gates, Steve Jobs, and a few others—have sought not just to build great companies but to take on problems that really matter. Yet even in this class of universe-denters, Musk stands out. After cofounding a series of Internet companies, including PayPal, the South African transplant could simply have retired to enjoy his riches. Instead he decided to disrupt the most difficult-to-master industries in the world. At 41 he is reinventing the car with Tesla, which is building all-electric vehicles in a Detroit-scale factory. (Wired profiled this venture in issue 18.10.) He is transforming energy with SolarCity, a startup that leases solar-power systems to homeowners.
And he is leading the private space race with SpaceX, which is poised to replace the space shuttle and usher us into an interplanetary age. Since Musk founded the company in 2002, it has developed a series of next-generation rockets that can deliver payloads to space for a fraction of the price of legacy rockets. In 2010 SpaceX became the first private company to launch a spacecraft into orbit and bring it back; in 2012 it sent a craft to berth successfully with the International Space Station.
It’s no wonder the character of Tony Stark in Iron Man, played by Robert Downey Jr., was modeled on Musk: This is superhero-grade stuff. I sat down with him at Tesla’s Fremont, California, factory to discuss how cheaper and (eventually) reusable rockets might someday put humans on Mars.
Chris Anderson: You’re not a rocket scientist by training. You’re not a space engineer.
Elon Musk: That’s true. My background educationally is physics and economics, and I grew up in sort of an engineering environment—my father is an electromechanical engineer. And so there were lots of engineery things around me. When I asked for an explanation, I got the true explanation of how things work. I also did things like make model rockets, and in South Africa there were no premade rockets: I had to go to the chemist and get the ingredients for rocket fuel, mix it, put it in a pipe.
Anderson: But then you became an Internet entrepreneur.
Musk: I never had a job where I made anything physical. I cofounded two Internet software companies, Zip2 and PayPal. So it took me a few years to kind of learn rocket science, if you will.
Anderson: How were you drawn to space as your next venture?
Musk: In 2002, once it became clear that PayPal was going to get sold, I was having a conversation with a friend of mine, the entrepreneur Adeo Ressi, who was actually my college housemate. I’d been staying at his home for the weekend, and we were coming back on a rainy day, stuck in traffic on the Long Island Expressway. He was asking me what I would do after PayPal. And I said, well, I’d always been really interested in space, but I didn’t think there was anything I could do as an individual. But, I went on, it seemed clear that we would send people to Mars. Suddenly I began to wonder why it hadn’t happened already. Later I went to the NASA website so I could see the schedule of when we’re supposed to go. [Laughs.]
Anderson: And of course there was nothing.
Musk: At first I thought, jeez, maybe I’m just looking in the wrong place! Why was there no plan, no schedule? There was nothing. It seemed crazy.
Anderson: NASA doesn’t have the budget for that anymore.
Musk: Since 1989, when a study estimated that a manned mission would cost $500 billion, the subject has been toxic. Politicians didn’t want a high-priced federal program like that to be used as a political weapon against them.
Anderson: Their opponents would call it a boondoggle.
Musk: But the United States is a nation of explorers. America is the spirit of human exploration distilled.
Anderson: We all leaped into the unknown to get here.

Few people change the course of human history and less realize that witnessing that change is important. Mainstream science is slow to change and it takes a hard-headed individual to fight against it.
Musk is such an individual and it will be interesting to see him outsmart ignorant public and political forces to achieve his stated goal of making mankind a multi-planetary species.
It will be fun to watch!

From Technology Review:
Two high-profile entrepreneurs say they want to put a DNA sequencing machine on the surface of Mars in a bid to prove the existence of extraterrestrial life.
In what could become a race for the first extraterrestrial genome, researcher J. Craig Venter said Tuesday that his Maryland academic institute and his company, Synthetic Genomics, would develop a machine capable of sequencing and beaming back DNA data from the planet.
Separately, Jonathan Rothberg, founder of Ion Torrent, a DNA sequencing company, is collaborating on an effort to equip his company’s “Personal Genome Machine” for a similar task.
“We want to make sure an Ion Torrent goes to Mars,” Rothberg told Technology Review.
Although neither team yet has a berth on Mars rocket, their plans reflect the belief that the simplest way to prove there is life on Mars is to send a DNA sequencing machine.
“There will be DNA life forms there,” Venter predicted Tuesday in New York, where he was speaking at the Wired Health Conference.
Venter said researchers working with him have already begun tests at a Mars-like site in the Mojave Desert. Their goal, he said, is to demonstrate a machine capable of autonomously isolating microbes from soil, sequencing their DNA, and then transmitting the information to a remote computer, as would be required on an unmanned Mars mission. (Hear his comments in this video, starting at 00:11:01.) Heather Kowalski, a spokeswoman for Venter, confirmed the existence of the project but said the prototype system was “not yet 100 percent robotic.”
Meanwhile, Rothberg’s Personal Genome Machine is being adapted for Martian conditions as part of a NASA-funded project at Harvard and MIT called SET-G, or “the search for extraterrestrial genomes.”
Christopher Carr, an MIT research scientist involved in the effort, says his lab is working to shrink Ion Torrent’s machine from 30 kilograms down to just three kilograms so that it can fit on a NASA rover. Other tests, already conducted, have determined how well the device can withstand the heavy radiation it would encounter on the way to Mars.
NASA, whose Curiosity rover landed on Mars in August, won’t send another rover mission to the planet before at least 2018 (see “The Mars Rover Curiosity Marks a Technological Triumph“), and there’s no guarantee a DNA sequencing device would go aboard. “The hard thing about getting to Mars is hitting the NASA specifications,” says George Church, a Harvard University researcher and a senior member of the SET-G team. “[Venter] isn’t ahead of anyone else.”
Venter has a great idea here, but it reminds me of a certain movie in which sequencing alien DNA wasn’t such a great plan.
Early today the Mars Rover ‘Curiosity’ using an untried, esoteric landing system, landed on Mars safely.
There was much bally-hoo over this system, but luck was on NASA’s side this time (50% of Mars landings fail). Now Curiosity begins it’s exploration of the Gale Crater in order to find evidence of past life, or conditions that supported it.
PASADENA, Calif. — NASA’s most advanced Mars rover Curiosity has landed on the Red Planet. The one-ton rover, hanging by ropes from a rocket backpack, touched down onto Mars Sunday to end a 36-week flight and begin a two-year investigation.
The Mars Science Laboratory (MSL) spacecraft that carried Curiosity succeeded in every step of the most complex landing ever attempted on Mars, including the final severing of the bridle cords and flyaway maneuver of the rocket backpack.
“Today, the wheels of Curiosity have begun to blaze the trail for human footprints on Mars. Curiosity, the most sophisticated rover ever built, is now on the surface of the Red Planet, where it will seek to answer age-old questions about whether life ever existed on Mars — or if the planet can sustain life in the future,” said NASA Administrator Charles Bolden. “This is an amazing achievement, made possible by a team of scientists and engineers from around the world and led by the extraordinary men and women of NASA and our Jet Propulsion Laboratory. President Obama has laid out a bold vision for sending humans to Mars in the mid-2030′s, and today’s landing marks a significant step toward achieving this goal.”
Curiosity landed at 10:32 p.m. Aug. 5, PDT, (1:32 a.m. EDT Aug. 6) near the foot of a mountain three miles tall and 96 miles in diameter inside Gale Crater. During a nearly two-year prime mission, the rover will investigate whether the region ever offered conditions favorable for microbial life.
“The Seven Minutes of Terror has turned into the Seven Minutes of Triumph,” said NASA Associate Administrator for Science John Grunsfeld. “My immense joy in the success of this mission is matched only by overwhelming pride I feel for the women and men of the mission’s team.”
Curiosity returned its first view of Mars, a wide-angle scene of rocky ground near the front of the rover. More images are anticipated in the next several days as the mission blends observations of the landing site with activities to configure the rover for work and check the performance of its instruments and mechanisms.
“Our Curiosity is talking to us from the surface of Mars,” said MSL Project Manager Peter Theisinger of NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “The landing takes us past the most hazardous moments for this project, and begins a new and exciting mission to pursue its scientific objectives.”
Confirmation of Curiosity’s successful landing came in communications relayed by NASA’s Mars Odyssey orbiter and received by the Canberra, Australia, antenna station of NASA’s Deep Space Network.
Curiosity carries 10 science instruments with a total mass 15 times as large as the science payloads on the Mars rovers Spirit and Opportunity. Some of the tools are the first of their kind on Mars, such as a laser-firing instrument for checking elemental composition of rocks from a distance. The rover will use a drill and scoop at the end of its robotic arm to gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into analytical laboratory instruments inside the rover.
To handle this science toolkit, Curiosity is twice as long and five times as heavy as Spirit or Opportunity. The Gale Crater landing site places the rover within driving distance of layers of the crater’s interior mountain. Observations from orbit have identified clay and sulfate minerals in the lower layers, indicating a wet history.
The mission is managed by JPL for NASA’s Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL. JPL is a division of the California Institute of Technology in Pasadena.
All in all, this is a feather in the cap of mainstream science and technology. Too bad we can’t get the benefit of full tech trickle down from the military-industrial-complex!

Calling up visions of the old Mars Radio Detector of 1924, the Square Kilometer Array ( SKA ) is a proposed technological marvel that will be able to detect alien radio signals and radars up to 50 light-years away:
If there are space invaders out there, it won’t be long before they can no longer stage a sneak attack, thanks to a project to build the most sensitive radio telescope ever — one that’s the size of a continent. Known as The Square Kilometer Array (SKA), it will explore the universe, identify any potential alien threats to our planet and hopefully answer some fundamental questions from astronomers. Its thousands of receptors, spaced roughly one kilometer apart, will be linked across an entire continent. They’ll be arranged in five spiral arms like a galaxy, 3,000 50-foot-wide dishes that extend out from a central core at least 1,860 miles (3,000 kilometers) — about the distance from New York City to Albuquerque, N.M. The board of directors behind the telescope met for the first time in late January to kick off the project. Their first decision: where to house such a beast. After all, if it’s located in Australia, the antennas could span the entire continent. If it’s in South Africa, another location being considered, they would stretch to the Indian Ocean islands. Optical telescopes can reveal only so much of the universe. The SKA’s radio telescopes, on the other hand, pick up radio-frequency signals unobscured by, say, cosmic dust. They will survey the sky 10,000 times faster than any other telescope and with 50 times the sensitivity and 100 times the survey speed of current imaging instruments. Among the SKA’s missions: finding an answer to the question, “Are we alone?” From a defense perspective, that’s a coy way of asking whether there are aliens out there with the capacity and appetite to attack us. The SKA will be able to detect very weak extraterrestrial signals and search for complex molecules, the building blocks of life. Many new planets outside our solar system have been discovered in recent years, but it’s not clear whether they host life.
The search for extraterrestrial transmission has been underway for a long time, but the SKA’s sensitivity will provide a key advantage. For the first time, it will even be possible to detect the relatively weak signals of televisions and radars from nearby stars. Spying such an artificial transmission from a planet around a star would be a pretty good clue that we’re not in this by ourselves.
The SKA will also look at how galaxies evolve and investigate the nature of dark energy. By mapping out the cosmic distribution of hydrogen, it will study the expansion of the universe after the Big Bang. Such a map will also allow researchers to track young galaxies. How were stars born and black holes formed? The SKA will study the very first ones, as well as stars and galaxies that shaped the development of the universe. It will even be able to detect black holes forming during the Dark Ages. SKA will also take on Einstein. The board of directors speculate that it may challenge the theory of general relativity and probe the nature of gravity. Initial construction is due in 2016, and the SKA is expected to be fully operational by 2024. By 2019, well before the full array is completed, the team expects some exciting science results will be achievable. All that science won’t come cheap, of course. The SKA is expected to cost approximately $2.36 billion. But those bucks buy an awful lot of power: The SKA’s central computer will have the processing power of approximately 1 billion PCs, and it will produce enough raw data to fill 15 million 64GB iPods every day. The SKA dishes will produce 10 times as much data the world’s Internet traffic. In fact, one of the largest design challenges was how to relay the huge amount of data across such large distances. The solution: Enough optical fiber to wrap twice around the Earth — and take the Earth’s defense to an entirely different scale.
The chances of finding another technological civilization at our level of tech within fifty light-years is pretty remote, but the kidnappers of Betty and Barney Hill are from Zeta Reticuli supposedly and that double star system is 37 light-years away.
I’m not sure what we’re going to do if we find ” space invaders ”, but I’m sure our military-congressional-industrial-complex will find a way to empty the pockets of the taxpayer to pay for the damn thing.
