At this point, the only things Mars One is likely to get into orbit are the wheels coming off of the bus
More background on the Mars One story.
From CTV News:
From NBC:
And (better late than never) from NPR:
From CTV News:
The Dutch non-profit group behind the project recently announced that it was pushing back the planned launch to 2027, due to a lack of funds for a robotic mission that was scheduled to precede the first human launch. The aim of the robotic mission is to test out the technologies required for human survival on Mars.
From NBC:
The Dutch-based Mars One venture is closing in on choosing its crews for one-way trips to the Red Planet, but will they be all dressed up in spacesuits with no place to go? Over the past week, there's been a string of reports that highlight the huge challenges facing Mars One.
Space News reports that the project's leaders haven't followed up on concept studies for robotic missions aimed at sending a lander and an orbiter to Mars in 2018. The Daily Mail says Mars One's deal with Endemol's global TV production team has fizzled out. Meanwhile, the Guardian quotes one of Mars One's initial supporters, astronomer Gerard 't Hooft, as saying the mission "will take quite a bit longer and be quite a bit more expensive" than advertised.
And (better late than never) from NPR:
Still, a Dutch venture called Mars One has captured the public's imagination with its plan to colonize Mars by 2025. Bas Lansdorp, the group's CEO, says they've been featured in major media outlets like CNN and the New York Times. "We've been on NPR — I think twice already," Lansdorp says.
...
"For some reason that I really cannot explain, I wanted to go to Mars and build a new human settlement there," he says.
Lansdorp believes the voyage will likely pay for itself because it will be a media spectacle. Everyone in the world will want to watch the whole adventure, he says. Mars One is planning a reality TV show with sponsorships and advertising.
"We expect it's worth up to 10 Olympic Games' [worth] of media revenue, which is $45 billion," says Lansdorp.
Of course, sponsors of the Olympics can be pretty confident that their games will happen. When asked how he responds to skeptics who say that Mars One is basically just a website and a marketing plan, Lansdorp says, "I think that the people who say that really haven't paid attention to what we've achieved already."
Lots of people applied to be part of the Mars One astronaut corps — paying a fee to do so. And the group has commissioned a couple of studies from established aerospace companies.
The Mars One plan calls for first sending out a small robotic lander in 2018. Lansdorp says he can do this more cheaply than NASA. But missions like that typically cost hundreds of millions of dollars. When told that it didn't sound like he'd raised anything like that amount of money, Lansdorp replied that "we don't need that kind of money yet because we're not yet building the actual lander. But these are the kinds of investments that we're currently in negotiation for."
How much has he raised? He won't say.

Rocket Boosters
Still collecting notes on the big Mars One post (see here, here and here).
One aspect of the story that I probably haven't spent enough time on is boosterism. As we try to reconstruct the journalistic wreckage of the collapsing story , it's essential to keep in mind the role that reporters' and commentators' attitude toward manned space exploration played. This is a story told, analyzed, and even critiqued largely by people who wanted it to be true.
Generally this attitude expressed itself in a "don't ask, don't tell" variant of confirmation bias: reporters for the most part simply did not go looking for details that would contradict the narrative. Occasionally, though, this lapsed into deliberate exaggeration, which brings us to Nobel Prize winning physicist, Dr. Gerard ‘t Hooft.
Dr. 't Hooft was an early and vocal advocate for the program (officially designated an "ambassador"). Here's an excerpt from his statement on the Mars One site:
[emphasis added]
That was 2013. Late in 2014, bad news started breaking rapidly, most notably an extraordinarily damning analysis from students at MIT. That report appears to have been a trigger for this shift in tone [emphasis added].
There was little chance of raising six billion dollars through sponsorships and reality shows;
There was even less chance of setting up a colony on that budget, let alone in the next ten years;
Even if the project could reach Mars, the technology is nowhere near where it would need to be to sustain the colonists.
T’Hooft probably didn't know much about television and the intricacies of entertainment accounting and it seems likely that he initially took the word the Mars One people about the state of the habitat technology, but when it came to budget and schedule, t’Hooft knew he was misleading people, even if he believed it was for a good causee.

Dr. 't Hooft was an early and vocal advocate for the program (officially designated an "ambassador"). Here's an excerpt from his statement on the Mars One site:
"Mars One is an extraordinarily daring initiative by people with vision and imagination. All confronted with it will, like I did, respond with skepticism: This will never work. NASA has had ideas like this on the books for decades, American President Bush wanted to launch a manned Mars mission too, and it never happened. Too costly, too complicated, and too chancy, even for NASA!Perhaps even more telling is this 2013 interview from New Scientist reprinted here by Slate.
But look and listen to this proposal properly! Problems are there to be solved. What is being put forward here is achievable! Here we have an enterprise that is financed exclusively by private firms, not the taxpayer’s dime. Rather than political mumbo-jumbo, we have real discussion with the general public. Only people who, like myself, are inspired by the project can contribute if they want. It will certainly be a spectacle worth watching. And, naturally, one thing stands front and centre: the technical feasibility.
...
This is when you ask me: aren’t you a scientist? What does science gain from this? Well, there are also scientific Mars missions. They cost a fraction of what this project will allocate. They are all robotic missions, but in the end science will be guaranteed to gain a great deal from human presence on various celestial bodies in our solar system. Universities don’t have the money for that. National governments have immediate priorities elsewhere. This project seems to me to be the only way to fulfill dreams of mankind’s expansion into space. It sounds like an amazingly fascinating experiment. Let’s get started!"
[emphasis added]
Govert Schilling: How did you get involved with a project that sells one-way tickets to Mars?In addition to the previously mentioned desire to believe which runs palpably through these statements, there are a couple of other aspects that should be noted. The first is the dissatisfaction with the pace of government-fund manned exploration. The second is the note of doubt that creeps in among the cheer-leading when the subject of budget and schedule comes up.
Gerard 't Hooft: The concept fits in with my own ideas about human exploration of space, which I described in my book, Playing with Planets. In fact, the co-founder and general director of Mars One, Bas Lansdorp, once attended one of my lectures. When he asked me to become an ambassador for Mars One, my first reaction was that it will take much longer and cost much more than they currently envision. However, after learning more about the research they had carried out, I became convinced that human flights to Mars could become a reality within 10 years. So in the end, I said yes.
...
GS: Wouldn't you prefer to be involved in a more scientific mission?
GtH: In a sense, this is a scientific project. There are many scientific questions that need to be addressed, and I am sure there will be plenty of scientific spin-offs, too. A lot of technological research on all aspects of the mission has already been carried out, and many of the major problems have been identified. One of the toughest problems is the radiation environment in interplanetary space. Then there needs to be research into the design of the space suits, the choice of the best location for the outpost on Mars, and the availability of water on the planet, in the form of ice. The plan is to grow food in greenhouses with artificial lighting, powered by efficient solar cells—this will involve a lot of interesting research. The most exciting question might be whether the whole idea is feasible at all. I welcome suggestions and queries from fellow scientists.
GS: How do you feel about being associated with a project funded by reality TV shows? Might you live to regret it?
GtH: Well, if people blame me for it, I have brought it on myself. However, this is the world we live in today—governments are not prepared to finance projects like Mars One, so the money has to come from some other source, and if it is a TV show like Big Brother or X Factor, then so be it.
Then again, I would rather not be involved with the TV show itself. And yes, at times I have asked myself what I have got myself into. After all, it does sound like a crazy plan. But so far, it is still fun, everything is still on track, and there do not appear to be any major obstacles. So I would tell my critics to let the facts speak for themselves.
GS: Would you encourage younger scientists to get involved?
GtH: It would not surprise me if it takes Mars One more than 10 years to put the first humans on Mars, and I can imagine it will cost more than the $6 billion currently envisioned. I have always been careful about those claims. If the project fails, my reputation may sustain some damage, but I am pretty sure I will survive that. Younger scientists, with their careers ahead of them, might run a bigger risk in that respect. Then again, I do not see how it could be held against you if you were to take part in technological design studies or in addressing various scientific issues.
That was 2013. Late in 2014, bad news started breaking rapidly, most notably an extraordinarily damning analysis from students at MIT. That report appears to have been a trigger for this shift in tone [emphasis added].
The budget and timeline for plans by a Dutch organisation to colonise Mars are highly unrealistic, one of the project’s most eminent supporters has suggested.Later
Gerard ’t Hooft, a Dutch Nobel laureate and ambassador for Mars One, said he did not believe the mission could take off by 2024 as planned.
“It will take quite a bit longer and be quite a bit more expensive. When they first asked me to be involved I told them ‘you have to put a zero after everything’,” he said, implying that a launch date 100 years from now with a budget of tens of billions of dollars would be an achievable goal. But, ’t Hooft added, “People don’t want something 100 years from now.”
A recent analysis by a team at the Massachusetts Institute of Technology (MIT) identified crucial flaws with Mars One’s published plans and predicted that even if the astronauts got to the surface unscathed, the first person would suffocate within 68 days because of a lack of equipment to balance oxygen levels effectively.Just to review, all three major stages of the Mars One proposal have turned out to be fatally flawed:
T’Hooft, of Utrecht University, said he was concerned by the findings. “I understand the scepticism very well. People from outside will say ‘wait a minute, you have to be careful with what you’re doing and what you’re claiming’. Maybe there’s a need to reassess,” he said.
He added that the “proper thing” would be for Mars One to publish its own analysis to demonstrate that their own more favourable projections about life on the Red Planet were sound.
Despite being sceptical about the details, t’Hooft said he still supported the project’s overall goals. “Let them be optimistic and see how far they get,” he said.
There was little chance of raising six billion dollars through sponsorships and reality shows;
There was even less chance of setting up a colony on that budget, let alone in the next ten years;
Even if the project could reach Mars, the technology is nowhere near where it would need to be to sustain the colonists.
T’Hooft probably didn't know much about television and the intricacies of entertainment accounting and it seems likely that he initially took the word the Mars One people about the state of the habitat technology, but when it came to budget and schedule, t’Hooft knew he was misleading people, even if he believed it was for a good causee.

First class tickets for ships that have sailed
[A quick side note. Bob Chipman, a film critic and pop culture historian whose work I enjoy and which I cited recently is no longer with the Escapist. If you want to keep up with his work, you can check out his blog here.]
The following is a nice example of putting popular culture in a business context. It also relates to an ongoing discussion I've been having with Joseph.
Joseph and I were discussing this very point about collectibles a few weeks ago as part of a larger conversation about investments and compensation, specifically cases where people made decisions in the hope of events repeating despite the fact that they were almost certainly a one time payoffs.
Growing up in Arkansas my go-to example is the Walmart millionaire box boy. Years before the stock took off, Sam Walton's wife convinced him to start a program that rewarded employees with either stock or stock options. When the boom came, a number of long-term employees found themselves very well compensated. As a result, virtually everyone in the area either knew someone or knew someone who knew someone who had become a millionaire from working a fairly low-wage job at Walmart.
These stories floated around for decades. They helped enourmously with morale and recruitment. People will tolerate a great deal for the possibility of a multimillion dollar payday down the road, but of course the boom was a one time event. By the time that people heard about the multimillionaire box boys, the last one of these had already been minted.
Joseph and I both saw a similar phenomenon working for you high-growth company in the early part of the millennium. The corporate folklore was filled with examples of people who had either gotten tremendous payouts from stock options or who had gone from the bottom to the top ranks of the company with shocking speed . Interns and secretaries who had become millionaires and vice presidents in the space of a few years.
For the most part, these anecdotes were true but that was largely beside the point. A few years earlier the company had been a start up now it was a major corporation. The career path and compensation associated with that particular transition were huge but there was no way they could be replicated once the company had arrived.
Of course, these stories didn't just spread by themselves. The companies in question did their best to make sure their employees knew that in the past there have been big pay offs . The result was a kind of false compensation. "We are not saying that your menial job here will lead to great wealth and position, but it has happened before." It is probably not a coincidence that Walmart's increasing labor problems seem to have picked up steam as the legends of millionaire cashiers faded.

Annals of unintended consequences
This is Joseph.
One issue with high stakes tests, regardless of who they are evaluating, is that there is a huge advantage to be gained by cheating. Transparency and social norms are usually the big tools here.
However, when it goes wrong, it can go very, very wrong.
Just one more thing to consider with educational testing.

Enhanced prototype demonstrations
I've spilled a lot of pixels criticizing tech reporters both for a lack of skepticism and historical perspective, so I highly recommend this article by Peter Baida which shows that the tendency to confuse good PR for innovation goes back to the very beginnings of American manufacturing.
Eli Whitney’s Other Talent
Though it took him a long while to master the art of musket making, Whitney was quick to master the art of obtaining extensions from government authorities. Part of his technique was to insist upon the revolutionary nature of the production methods he was developing. As early as July 1799, he explained to worried officials that his factory would embody a “new principle” of manufacturing: “One of my primary objects,” he wrote to Secretary of the Treasury Oliver Wolcott, “is to form the tools so the tools themselves shall fashion the work and give to every part its just proportion—which when once accomplished, will give expedition, uniformity, and exactness to the whole....In short, the tools which I contemplate are similar to an engraving on a copper plate from which may be taken a great number of impressions perceptibly alike.”
This is a description, and an elegant one, of the principle of “interchangeable parts.” If machine tools make parts of a weapon (or other product) so “perceptibly alike” that broken parts can be replaced without special fitting, then the parts are said to be interchangeable.
Though Whitney spoke of adopting a “new principle” in his factory, not even his most ardent defenders credit him with discovering the principle of interchangeable parts. Years before Whitney contracted to manufacture muskets, a Frenchman, HonorĂ© Blanc, was making musket firing mechanisms (“locks”) on the interchangeable system. Thomas Jefferson saw a demonstration of Blanc’s work in 1785: “He presented me with the parts of fifty locks taken to pieces, and arranged in compartments. I put several together myself, taking pieces at hazzard as they came to hand, and they fitted in a most perfect manner.”
If Whitney did not introduce the principle of interchangeable parts, might he not have been the first American to make practical use of the principle? Modern researchers have tested the Whitney firearms that survive, with results that astonished those who had grown up believing the Whitney legend. The tests showed that, in some respects, the parts of Whitney’s firearms were not even approximately interchangeable. Moreover, many parts of Whitney’s muskets are engraved with special marks—marks that would only be necessary if the manufacturer had failed to achieve interchangeability.
These discoveries raise another question. An episode that figures prominently in the Whitney legend is a demonstration that he made in Washington in January 1801 before an audience that included President Adams and Presidentelect Jefferson. “Mr. Whitney,” Jefferson later wrote to James Monroe, “has invented moulds and machines for making all the pieces of his locks so exactly equal, that...the hundred locks may be put together as well by taking the first pieces which come to hand.”
In view of the deficiencies of the firearms that survive, how are we to explain the demonstration of 1801? Merritt Roe Smith, one of our foremost authorities on the history of arms manufacture, concludes that only one explanation makes sense: “Whitney must have staged his famous 1801 demonstration with specimens specially prepared for the occasion....it appears that Whitney purposely duped government authorities...[and] encouraged the notion that he had successfully developed a system for producing uniform parts.”
...
So far, so bad, but there’s more! “By his tenacity he so perfected the manufacture of arms that with the subsequent adoption of his system...the government saved $25,000 annually”—so says the Dictionary of American Biography, which goes on to give Whitney credit (as do Nevins and Mirksy) for an invention of exceptional importance in the history of manufacturing: “Of the various machines designed and used by Whitney only one is known to exist. This is a plain milling machine which was built prior to 1818, and is believed to be the first successful machine of its kind ever made.”
It’s bad enough to discover that you can’t count on the things you learned in the seventh grade, but you know you’re really in trouble when you realize that you can’t count on the Dictionary of American Biography. In “Eli Whitney and the Milling Machine,” published in the Smithsonian Journal of History in 1966, Edward A. Battison concludes: “There is no evidence that Whitney developed or used a true milling machine.” The so-called Whitney machine of 1818 seems actually to have been made after Whitney’s death in 1825. The first true milling machine was made not by Whitney, Battison suggests, but by Robert Johnson of Middletown, Connecticut.

Elmo Keep's other must-read on Mars One
I don't have time today to do more than post a few quotes, but it's definitely something you should read if you've been following this story.
Mars One Finalist Explains Exactly How It‘s Ripping Off Supporters
But eventually Joseph — who is actually Dr. Joseph Roche, an assistant professor at Trinity College’s School of Education in Dublin, with a Ph.D. in physics and astrophysics — found himself on the group’s shortlist of 100 candidates all willing to undertake the theoretical journey. And that’s when he started talking to me about the big problems he was seeing with Mars One.
It was difficult for him to break his silence, but he was spurred into speaking out by the uncritical news coverage. Many basic assumptions about the project remain unchallenged. Most egregiously, many media outlets continue to report that Mars One received applications from 200,000 people who would be happy to die on another planet — when the number it actually received was 2,761.
...
“When you join the ‘Mars One Community,’ which happens automatically if you applied as a candidate, they start giving you points,” Roche explained to me in an email. “You get points for getting through each round of the selection process (but just an arbitrary number of points, not anything to do with ranking), and then the only way to get more points is to buy merchandise from Mars One or to donate money to them.”
“Community members” can redeem points by purchasing merchandise like T-shirts, hoodies, and posters, as well as through gifts and donations: The group also solicits larger investment from its supporters. Others have been encouraged to help the group make financial gains on flurries of media interest. In February, finalists received a list of “tips and tricks” for dealing with press requests, which included this: “If you are offered payment for an interview then feel free to accept it. We do kindly ask for you to donate 75% of your profit to Mars One.” [Bold in original.]
...
So, here are the facts as we understand them: Mars One has almost no money. Mars One has no contracts with private aerospace suppliers who are building technology for future deep-space missions. Mars One has no TV production partner. Mars One has no publicly known investment partnerships with major brands. Mars One has no plans for a training facility where its candidates would prepare themselves. Mars One’s candidates have been vetted by a single person, in a 10-minute Skype interview.

Another Mars One update
I'm chipping away at a longer piece on Mars One, which means I'll be recycling some of my notes...
Mars One Suspends Work on Robotic Missions by Jeff Foust — February 18, 2015Another area of concern was funding. The original plan was wildly ambitious, requiring Olympic-level profits from a proposed reality show, but the company had managed to line up an experienced partner to produce the show. Now even that is in question.
WASHINGTON — A private organization that recently selected finalists for one-way human missions to Mars in the mid-2020s has quietly suspended work on a pair of robotic missions, putting into question plans to launch those spacecraft in 2018.
Mars One, a Dutch-based nonprofit organization, announced in December 2013 it was starting work on two robotic missions it planned to launch in 2018 as precursors to its human expeditions to Mars. One spacecraft would orbit Mars and serve as a communications relay, while the other would be a lander to test technologies planned for later crewed missions.
At that time, Mars One announced it had selected Lockheed Martin to begin work on the lander mission and Surrey Satellite Technology Ltd. (SSTL) to start work on the orbiter. Mars One awarded contracts to each company to perform concept studies of the planned missions.
“These missions are the first step in Mars One’s overall plan of establishing a permanent human settlement on Mars,” Bas Landsorp, Mars One chief executive and co-founder, said in a December 2013 press conference here announcing the missions. “We believe we are in very good shape to make this happen.”
However, both companies confirmed with SpaceNews that, since the completion of those study contracts, they have not received additional contracts from Mars One to continue work on those missions.
“SSTL delivered the concept study for the Mars One communications system last year,” SSTL spokeswoman Joelle Sykes said Feb. 16. “There are no follow-on activities underway at the moment.”
“Lockheed Martin has concluded the initial contract with Mars One in which we performed mission formulation studies and developed payload interface specifications to support the selection of a payload suite for the 2018 Mars robotic lander,” the company said in a statement Feb. 17. “We continue to maintain an open channel of communications with Mars One and await initiation of the next phase of the program.”
...
Those plans, though, may depend on the progress Mars One makes on its robotic missions, and there time is of the essence. Lockheed Martin noted in its statement that its proposed Mars One lander is based on a “very mature” design used on NASA’s Phoenix Mars Lander mission launched in 2007 and the InSight lander it is building for launch in March 2016.
Despite that heritage, the company said, “we would have to start construction very soon to launch an InSight clone in the 2018 window.”
No more 'Big Brother' on the red planet: Endemol axes plans for reality TV show that would record life of Mars One explorers - but a documentary will still be made
By SARAH GRIFFITHS and JONATHAN O'CALLAGHAN, 23 February 2015
Last week Mars One announced a list of 100 people who will train on Earth for a one-way mission to the red planet in 2025.
But the venture's accompanying reality TV show - which was to be made by the makers of Big Brother to document their training and new lives on the red planet - has been shelved after the companies were 'unable to reach an agreement on details', MailOnline has learned.
Instead, Mars One is working with a new production company to record the colonists' progress.
It is unclear whether the breakdown in communications may blow a hole in Mars One's already tight $6 billion (£4 billion) budget because TV rights were expected to help finance the majority of the mission.
So far less than $760,000 (£496,000) has been donated to cover the estimated total cost, and time is of the essence.
However, Bas Lansdorp, co-founder and CEO of Mars One, told MailOnline that the idea of a television programme providing a hefty chunk of funding was a 'big misconception'.
'Media exposure is one of our business cases. Funding for the mission will come mostly from equity investors,' he said.
'The return on their investment will come when the first crew leaves or even when it lands: that's when the revenues from the media exposure are much larger than the cost of the mission.'
He said the documentary will 'involve more people in our adventure,' but declined to name the production company that will make the programme.
Initially, there were plans for Endemol to make a reality TV programme documenting the selection process and training of the colonists.
It was to be made by Endemol-owned Darlow Smithson Productions (DSP) and was dubbed 'Big Brother on Mars'.
But DSP told MailOnline: ‘DSP and Mars One were unable reach agreement on the details of the contract and DSP is no longer involved in the project.
'We wish Bas and the team all the very best.’
It is unclear when the decision was made, although Endemol originally said that the first installments of the TV show would air in early 2015.
Lansdorp also told MailOnline: 'We have ended our cooperation with Endemol because we could not reach agreement on the details of the contract.
'We have contracted a new production company that will produce the documentary series for us.
'They have already produced the trailer on our Youtube channel and progress is good.'

The Mars conversation I'd like to be having
As a bit of an antidote for all the accumulated bile of the last few Mars One posts, I'd like to recommend this IEEE paper from Ian McNab. I'll admit it lost me on the curves a few times, but on the whole it's remarkably readable.
From the introduction:
Let's think about the question of why so many reputable news organizations are devoting so much coverage to Mars One and so little to other, better aerospace stories such as this one.
What do I mean by better?
For starters, this is a credible proposal from a well-established authority published in an IEEE journal, and, based on my experience, it's an idea that other engineers in the field are not willing to dismiss out of hand; they may not consider it practical, but they do take it seriously. (For example, JPL was looking into using orbiting railguns to launch small interplanetary probes as far back as 1988.)
And we really are talking about a game-changer here. If McNab's estimates hold up, we're talking about reducing launch costs by considerably more than an order of magnitude. Even if we factor in the need to use traditional rockets for people and other delicate cargo, that cost reduction is still enough to shift the underlying economics of all space-based enterprises, ranging from asteroid mining to tourism to, yes, interplanetary colonies.
Finally, rail guns are cool. All Mars One has to offer is cheesy artist conceptions. With railguns you get video like this:
This is, of course, just one example. There are any number of fascinating stories about aerospace research. Why do they go unnoticed while Mars One continues to make the cut? Here are my guesses:
1. Bullshit does not count against you. As Elmo Keep spelled out in painful detail, every aspect of this story collapses under inspection, but even after Keep's expose, the stories kept coming;
2. People love a bargain (i.e. there's a sucker born every minute). I've noticed a number of cases recently where an unrealistically low price seems to make proposals more newsworthy (this example jumps to mind);
3. Everybody loves a messiah (even a Galtian one). Entrepreneurs and market forces are also easy pitches these days, while stories of public action and collective sacrifice fall out of favor. Of course, even in the Sixties, space was a tough sell (even as we were sending men to the moon, people were suggesting that the money would have been better spent down here), but now even the suggestion that we as a society would take on something expensive and challenging seems oddly quaint.
From the introduction:
In the past 40 years, mankind has ventured into space using well-established rocket technology involving liquid fuels and/or solid propellants. This approach has the advantage for astronauts and fragile payloads that the rocket starts slowly from the surface of the Earth with its full fuel load, and, as the fuel is burned off, the altitude and speed increase. In addition to minimizing the aerodynamic and aerothermal loads, this provides relatively modest accelerations—maximum values of a few “gees” are used for human passengers. Because only a small fraction of the initial mass reaches orbit, rockets of substantial size are required to place tens of tons into near-Earth orbit. Offsetting these remarkable successes is the very high cost of burning chemical fuel with a modest efficiency in a rocket engine to get out of the Earth’s gravitational well. Present estimates are that it costs $20 000 to get one kilogram of material into orbit. Unless alternatives can be found, it seems likely that mankind’s ventures into space will be limited to a few adventures that can only be undertaken by wealthy nations—the science-fiction writer’s dream of colonizing the planets and stars may be unaffordable.
Proposed solutions fall into four general categories: better rocket propellants; the space elevator; gun launch from the Earth’s surface; and laser launch. Although these options will not be discussed in detail, a few comments are appropriate. First, there appear to be no acceptable alternative rocket propellants that can offer substantial improvements compared with present choices. Second, although the space elevator seems to have great promise as a concept for the future, its practical realization awaits the development of a material that is strong enough to be able to carry its own weight (and that of the payloads it will lift) from the Earth’s surface to geosynchronous orbit. Third, estimates indicate that to launch payloads of less than a ton with a laser would require multigigawatt lasers far larger than any presently in existence
[Having concluded that gun launches are currently the most viable option, McNab starts drilling down into the details.]
...
If the launcher is sufficiently long, the acceleration can be reduced to a level that is compatible with present component technology, although the acceleration forces will not allow people or fragile payloads to be launched with feasible launcher lengths. Guns may therefore be limited to launching robust packages such as food, water, fuel, and replaceable components. This may be an important support function for the International Space Station (ISS) or other missionsI don't want to get into whether or not we should be spending more on space exploration, and I certainly don't want to argue the merits of this proposal (that topic would take me out of my depth almost immediately). For now, I want to stay meta and discuss the discussion.
A disadvantage of gun launch is that the launch package has to leave the gun barrel at a very high velocity ( 7500 m/s) through the Earth’s atmosphere, leading to a very high aerothermal load on the projectile. The reentry vehicle community has successfully developed techniques to overcome this situation (when traveling in the reverse direction), and it seems possible that similar techniques can resolve this problem, either through the use of refractory or ablative nose materials or by evaporative cooling techniques. The mass of coolant required for this appears to be acceptable, as discussed below. The second concern for a gun is the size of the package that can be launched. Unless a very large gun can be built, the payload launched into orbit per launch will be a few hundred kilograms, which will require a large number of launches per year. For example, to provide 500 tons/year to orbit would require 2000 launches/year—a little over five per day on average. An infrastructure in space for handling this traffic and distributing the payloads will have to be created. Issues to be addressed will include decisions on handling or recycling the nonpayload components that reach orbit.
Let's think about the question of why so many reputable news organizations are devoting so much coverage to Mars One and so little to other, better aerospace stories such as this one.
What do I mean by better?
For starters, this is a credible proposal from a well-established authority published in an IEEE journal, and, based on my experience, it's an idea that other engineers in the field are not willing to dismiss out of hand; they may not consider it practical, but they do take it seriously. (For example, JPL was looking into using orbiting railguns to launch small interplanetary probes as far back as 1988.)
And we really are talking about a game-changer here. If McNab's estimates hold up, we're talking about reducing launch costs by considerably more than an order of magnitude. Even if we factor in the need to use traditional rockets for people and other delicate cargo, that cost reduction is still enough to shift the underlying economics of all space-based enterprises, ranging from asteroid mining to tourism to, yes, interplanetary colonies.
Finally, rail guns are cool. All Mars One has to offer is cheesy artist conceptions. With railguns you get video like this:
This is, of course, just one example. There are any number of fascinating stories about aerospace research. Why do they go unnoticed while Mars One continues to make the cut? Here are my guesses:
1. Bullshit does not count against you. As Elmo Keep spelled out in painful detail, every aspect of this story collapses under inspection, but even after Keep's expose, the stories kept coming;
2. People love a bargain (i.e. there's a sucker born every minute). I've noticed a number of cases recently where an unrealistically low price seems to make proposals more newsworthy (this example jumps to mind);
3. Everybody loves a messiah (even a Galtian one). Entrepreneurs and market forces are also easy pitches these days, while stories of public action and collective sacrifice fall out of favor. Of course, even in the Sixties, space was a tough sell (even as we were sending men to the moon, people were suggesting that the money would have been better spent down here), but now even the suggestion that we as a society would take on something expensive and challenging seems oddly quaint.

Corporate PR vs. Beat Sweetening -- different but not that different
Brad DeLong recently provided an interesting complement to our ongoing flack-n-hacks thread (which Andrew just joined). Just to review, we were talking about how PR firms (the 'flacks' in question) provide leads, leg-work and even finished copy in exchange for favorable coverage. DeLong uses this embarrassing Politico puff piece of Stephen Moore to examine the way journalists trade favorable coverage for access and scoops (which is, more or less, Politico's unofficial mission statement).
This piece is what my old next-door office neighbor Jack DeVore, then Treasury Secretary Lloyd Bentsen's Assistant Secretary for Public Relations, called a "beat sweetener": the point of such an article is not to inform the article's readers about some person regarded as either being influential or typical in an interesting way, but rather to burnish the reputation of the subject. As such, it omits key parts of the story and so misleads the readers in the interest of achieving that goal. The hope is that the subject of the article will at some future point then open up and preferentially dish to the reporter who has done him the favor of burnishing his reputation.
...
That is it. No observations about publishing the wrong numbers. No observations about how Stephen Moore has been a huge backer of Sam Brownback's Kansas tax-cut state revenue disaster. Nothing about how Herman Cain' 9-9-9 plan blew up in his face because no analyst who could add could get it to work arithmetically no matter how many thumbs they put on these scale. No critical quotes from anybody about the quality of Stephen Moore's analytical work--which would have been the easiest thing in the world to get. In fact, no positive quotes at all from any economist about Stephen Moore as an economist or an analyst.
...
So the message I get from this is that there is, still, an enormous need for publications and platforms that will call a spade a goddam shovel, afflict the comfortable, entertain-along-with-informing rather than entertain-instead-of-informing, and be trusted information intermediaries in which the words on the page are there to inform you about what is what rather than to mislead you in the hope that those in whose interest you have been misled will at some point in the future dish the writer a scoop.

More on the rise of PR
Living in North Hollywood, one gets plenty of notice of the upcoming Emmy season. Perhaps even more then with the Oscars, this award show is preceded by a blanketing of the neighborhood in "For your consideration" billboards. You can get a rough but reasonable idea of who is spending what by looking at how many billboards you see for different shows and different networks.
Per show, at least, there seems to be a huge disparity between Netflix originals and virtually everybody else. Billboards for House of Cards or Orange Is the New Black are all over the place. By contrast, I don't recall seeing an Emmy ad for Orphan Black or Justified or even the Good Wife. On this per show basis, it would certainly appear that the Emmy-season outdoor advertising budget for Netflix is many times larger than that of its nearest competitor.
I don't want to get into the question of whether or not this is a good business decision on the part of Netflix and I certainly don't want to open the topic of which awards were deserved. Instead, I want to tie this into the previous post on the rise of PR and the decline of journalism.
I read any number of pieces about how winning Emmys meant that Netflix had "arrived." As far as I can remember, none of these articles mentioned the disproportionate level of marketing it took to win these awards. Of course, omitting context is a common sin, particularly when the details undercut the standard narrative (adherence to the standard narrative is pretty much the prime directive of modern journalism), but there is an added layer of conflict of interest here.
The practice of letting interested parties research stories and even write copy is as old as typesetting, but there is reason to believe things have gotten much worse. What was once an occasional lapse now appears to be the norm.
Modern journalism is now basically row upon row of glass houses. Stone-throwers have become decidedly unpopular (check out the NYT's attitude toward Nate Silver). Even if a reporter wasn't beholden to some publicist, he or she would still face considerable pressure from colleagues and editors not to make a big deal of these questionable relationships.
I realize I seem to pick on Netflix a lot, but I really don't have a serious problem with the company. My problem is with the way today's journalists cover business, neglecting due diligence, allowing conventional wisdom to outweigh facts, and letting companies write their own version of reality.
Netflix just happens to be a great example.

A premature diagnosis of cost disease?
After cuts in state funding, the most popular theory to explain the rapid increase in college tuition seems to be cost disease:
If this post by Paul Campos of Lawyers, Guns and Money is accurate, the theory is even more at variance with the facts that I thought. ( Campos also has some interesting things to say about the drop in state funding explanation.)
Baumol's cost disease (also known as the Baumol Effect) is a phenomenon described by William J. Baumol and William G. Bowen in the 1960s.[1] It involves a rise of salaries in jobs that have experienced no increase of labor productivity in response to rising salaries in other jobs which did experience such labor productivity growth. This seemingly goes against the theory in classical economics that wages are closely tied to labor productivity changes.I've never felt entirely comfortable with the way this explanation fits (or fails to fit) the data. It always seemed to me that the tremendous increase in very low-priced adjunct labor would more than balance out the flat productivity gains.
If this post by Paul Campos of Lawyers, Guns and Money is accurate, the theory is even more at variance with the facts that I thought. ( Campos also has some interesting things to say about the drop in state funding explanation.)
Everyone is aware that the cost of going to college has skyrocketed since [fill in any date going back to the middle of the last century]. Why has this happened? This post is about one possible explanation, that turns out not to have any validity at all: increases in faculty salaries. In fact, over the past 40+ years, average salaries for college and university faculty have dropped dramatically.
Salaries have increased, sometimes substantially, for a tiny favored slice of academia, made up of tenured professors at elite institutions, some professional school faculty (business, law, medicine), and most especially faculty who have moved into the higher echelons of university administration. Such examples merely emphasize the extent to which the economics of the New Gilded Age have infiltrated the academic world: the one percent are doing fabulously well, and the ten percenters are doing fine, while the wretched refuse of our teeming shores will adjunct for food.
Numbers:
Average salary for all full-time faculty in degree-granting post-secondary institutions (this category includes instructors and lecturers, as well as all ranks of professors) in constant 2012-13 dollars:
1970: $74,019
2012: $77,301
These figures, of course, give a very incomplete picture of the economic circumstances of the actual teaching faculty in America’s institutions of higher education.
One of the more astonishing statistics regarding the economics of our colleges and universities is that, despite the fantastic increase in the cost of attending them, there are now on a per-student basis far fewer full-time faculty employed by these institutions than was the case 40 years ago. Specifically, in 1970 nearly 80% of all faculty were full-time; by 2011, more part-time than full-time faculty were employed by American institutions of higher learning (note that the former category does not include graduate students who teach).
While comprehensive salary figures for part-time faculty aren’t available, it’s clear that their salaries are on average vastly lower than those of full-time faculty (and of course when it comes to who does the bulk of the actual teaching at many schools, the designations “full-time” and “part-time” have a distinctly Orwellian flavor). If we assume that “pat-time” faculty earn one-third as much as their full-time counterparts — and this seems improbably optimistic, given that the average compensation for part-time faculty for teaching a three-credit course is around $2,700 — that would mean that in 1970 average salaries for college and university faculty were nearly 30% higher, in real dollars, than they are today.
This an astonishing figure, given that, in the last 40 years, tuition at private colleges has more than tripled, while resident tuition at public institutions has nearly quadrupled.
