SpaceX Aims To Put Man On Mars In 10-20 Years

As to who is going to pay for that rocket remains the question. I, too, am skeptical that commercial spaceflight is going to expand significantly such that a purely commercial venture to Mars will happen within the next decade or two. Here are some sources of commercial spaceflight revenue at the moment:

      • Communications - Already a very mature segment of spaceflight, telecommunications satellites of various flavors are perhaps the one sure business case for spaceflight. SpaceX already has the contract for the next generation of Iridium satellites, and other companies are currently in negotiations with them.
      • Reconnaissance - While it seems odd that such satellites are used for commercial purposes, it is something that is legitimately being used. The last Falcon 1 launch carried a survey satellite for Indonesia, and there are other commercial companies who sell survey images (like Google Earth) for various commercial activities. This is on top of military payloads from the National Reconnaissance Office or even weather satellites put up by NOAA.
      • Scientific Payloads - SpaceX and other commercial spaceflight companies are now getting cheap enough that more modest research proposals are affordable. More importantly, it is a pent-up demand for scientific research in space because getting space on the Shuttle has been almost impossible for so long. There are private research foundations who can and likely will be involved in purchasing space on various launches in the future. Iridium is taking advantage of this by offering space on their satellites for scientific payloads, as is SpaceX with their DragonLab vehicle that is scheduled to go up some time next year or in 2013. Rather than waiting a decade just to get a "slot" for a launch, researchers in space can finally get multiple opportunities to fly in the same year and do multiple iterations on the scientific research. This is going to be huge and may be the bulk of commercial spaceflight revenue for the next decade.
      • Tourism - This is the unpredictable wildcard for commercial spaceflight. Of all of the various applications that has a proven track record, it is tourism that will respond better with reduced launch costs. Virgin Galactic is but the first of many companies already taking deposits on spaceflight, and Space Adventures has been flying people in space for several years now. The market for space tourism is still quite small, but people like Robert Bigelow are betting a huge sum of money thinking it will become very big.

      Technically, SpaceX is required by law to declare a profit off of the Falcon rockets due to the fact that they have taken deposits and that the rockets they have in the production queue are at certain stages of delivery. This is similar to other companies that produce "durable goods" and items that require significant capital investment, so it isn't unique to SpaceX. As a result, SpaceX has been in the black for a couple of years now and is indeed making a profit. That flights have been happening only makes that work out all that much more.

      What hurts me the most is to see things like the OTRAG and the Constogea get killed strictly for political reasons. Constogea in particular was killed by none other than the Space Shuttle program, where NASA at the time published a payload price schedule for commercial loads that simply was a pure fabricated lie of the worst kind. Not only could NASA not meet that price point (as if NASA was a commercial entity unto themselves.... they fancied themselves at the time as a space version of the Post Office Department), but they simply didn't even fly more than a couple commercial payloads and then in turn canceled that program entirely when the Challenger blew up.

      If you want to see something really horrid, I'd suggest reading up on the Telstar satellites put up by AT&T. AT&T paid an extra premium for the launch of that satellite and had to get special authorization from Congress in the form of a law that explicitly gave permission for just that one launch. Here was a company flowing with money and wanting to take advantage of going into space, yet because the satellite wasn't invented by or built with engineers from NASA or the Department of Defense, they had to jump through extra hurdles just to get it into space. Once the satellite actually got up into space and then proven to be a profitable business (telecommunications satellites), what did Congress do to thank AT&T for their investment in this area? They granted a monopoly to one of AT&T's competitors and by law killed the space technology division at AT&T (since they couldn't really send anything up into space any more).

      I could go on as there have been many other attempts to get real private commercial spaceflight to happen. MIRcorp was another example of some very forward thinking that was killed by the U.S. government.... and quite recently too. Unless you have provided prostitutes, generous campaign contributions, and brought key congressmen out to very fancy restaurants (and of course offered them a speaking fee as well as purchasing copies of their autobiography), you simply won't get a successful business running in space.

      This dismal situation changed a little bit with the Ansari X-Prize, where at last commercial spaceflight could prove they could make something to at least go into space without NASA or for that matter any government financing. Many said it couldn't be done. The key is to prove them wrong and show that people can go into space on their own dime if you can keep the government out of their hair.

      The most significant event in the past decade for spaceflight was the passage of the Commercial Spaceflight Act that established the FAA-AST as the government agency with the authority to regulate commercial spaceflight activities in America. Until that happened, nobody could legally go into space even if they wanted to without a congressional commission. After that happened, finally a private citizen could do stuff in space. I get that you need to prove you aren't going to fly your rockets into the Empire State Building or do something else equally stupid that could really hurt others, but the red tape reduction has really made a difference.

      Terminal velocity is the speed at which acceleration caused by gravity is equal to the deceleration effect caused by air resistance (which increases as speed increases). In a vacuum, terminal velocity would be close to the speed of light (and the object's mass would increase a lot before then, which would increase the acceleration).

      My point is that every time the object goes from the low portal to the high portal, it is gaining gravitational potential energy. If it fell at terminal velocity for a long time, then the air resistance would cause it to heat up. This energy has to come from somewhere and the most likely place is the ambient energy (temperature) at one end of the portal. When you go from a high portal to a low portal, there is a net energy loss. When you go from a low portal to a high portal, there is a net energy gain. If you're only travelling a few vertical metres, then this energy change is only going to raise (or lower) the air / wall temperature by a fraction of a degree, and will be unnoticeable.

      What makes Mars so nasty is that it has an atmosphere which has to be dealt with (heat shields are necessary, and aerobraking is useful to consider), but at the same time it is so thin that it can't be relied upon to really help you out at the most critical time of landing like it does here on the Earth or on Venus and Titan. Essentially it is very easy to either burn up or go smack onto the surface, and has an entirely different engineering realm in terms of being able to successfully land or take off from the surface of Mars. So far, nothing has ever been able to take off from the surface of Mars and return back to the Earth, shy of a very large meteor that dislodged whatever it is that made it to the Earth.

The first project to implement a time-sharing system was initiated by John McCarthy in late 1957, on a modified IBM 704, and later on an additionally modified IBM 7090 computer. Although he left to work on Project MAC and other projects, one of the results of the project, known as the Compatible Time-Sharing System or CTSS, was demonstrated in November 1961. CTSS has a good claim to be the first time-sharing system and remained in use until 1973. Another contender for the first demonstrated time-sharing system was PLATO II, created by Donald Bitzer at a public demonstration at Robert Allerton Park near the University of Illinois in early 1961. Bitzer has long said that the PLATO project would have gotten the patent on time-sharing if only the University of Illinois had known how to process patent applications faster, but at the time university patents were so few and far between, they took a long time to be submitted. The first commercially successful time-sharing system was the Dartmouth Time Sharing System."

In the 1950s it was ten years (which is why Project Sherwood was highly classified - they expected fusion power would be a big national security asset in the near future. By the 1970s it was 25 years. Now, a full 60 years since fusion power research started, it is roughly estimated that the first prototype power plant might start operation in 50 years or so. The successful full operation of Iter, which will be necessary to design this prototype is 20 years away even though it is under construction now.

    But it is very questionable whether magnetic confinement D-T fusion power will work at all - for reasons having nothing to do with reaching the necessary plasma parameters, which is the focus of all current research efforts. I count three reasons - two of which are related to the breeding blanket.

    First, the breeding blanket is a huge complex structure that has such stringent design requirements no one can demonstrate that is possible to build one (it has to have effectively no parasitic neutron absorption), it has been observed that more important than the current fusion plasma research, a project as big as Iter should be started simply to develop a viable blanket system, or prove it cannot be done.

    Second, the breeding blanket capital costs (counting only the raw materials) alone will make fusion power much more expensive than fission power, which is currently crippled by its high capital costs.

    Third, a magnetic confinement fusion plant houses a multi-gigawatt power source inside a huge container cooled internally to near absolute zero. The problem of extracting this heat successfully and productively is another enormous unsolved engineering problem being kicked down the road.

    A non-viable D-T power plant might be a stepping stone, a century or so from now, to a viable He-3 fueled plant (because it makes the breeding blanket problem go away).

The actual energy cost of getting to orbit (8.7 kWh/kg) runs about $1/kg at typical retail electric rates. An efficient transportation system would run something like 4 times the bare energy cost, which works out to about the cost of UPS shipping or ground beef.

    Keep in mind that Moore's law works for chips because a 50% drop in price can increase sales by 500% (more or less.... follow me on this point for a moment). Back in about 1950, the total number of computers being manufactured could fit on one hand, and there was a famous economist who honestly predicted that the total number of computers needed world-wide was just five. Considering the applications at the time, that was actually a fair estimate and you could even name off the customers (U.S. Army, Census Bureau, IRS, a consortium of banks, and one for Europe).

    Gordon Moore himself gave a talk at a conference about microprocessors about 1970 where the discussion was about the number of microprocessors that might be needed world-wide. They did realize at the time the number was a bit more than five, but based upon growth trends they tried to predict how many microprocessors might be manufactured by the year 2000. They came up with something close to about 10 billion CPUs.... and then somebody gave a remark that would imply there would be a microprocessor for every doorknob in all the hotels of the world... making a joke. A subsequent conference by many of the same people happened in 2000.... and sure enough there were microprocessors in every doorknob of the hotel where the conference was being held... and those really weren't remarkable by that time. This has happened because the demand for those processors is almost insatiable and as the price drops many new applications can be found to use those processors. There are now legitimate applications (RFID tags, for instance) where having a microprocessor for 10 cents is still too expensive.... so cheaper processors are being made where every can of Coca-Cola could conceivably have a microprocessor.

    Bringing this to spaceflight, the issue is how can you find some markets for spaceflight where a 50% drop in the price to orbit will give you more than a 100% increase in flights? So far, the opposite has been happening, where a 50% drop in price only gets you a 10%-20% increase in customers. That is a horrible position to be in unless you are also stealing customers (as SpaceX is doing) from other launcher companies due to you being a new entrant in the market.

    This is precisely why many have suggested that SpaceX may eventually raise prices for launches, because the market will bear the price. If they raise prices 100% and only lose 20% of their customers in the process.... what do they have to lose? That is precisely what Boeing, Lockheed-Martin, and the other traditional launcher groups have been doing for some time. Putting a communications satellite into orbit that costs billions of dollars to manufacture in the first place can easily afford to spend a quarter of a billion on launching costs.... so they don't care if they spend a little more as long as the rocket is reliable or at least covered by insurance if it fails. This is also why launch costs until recently have been increasing much faster than inflation.

    If we can find some markets for spaceflight (space tourism BTW is one of those markets) where the number of customers increases substantially with even a modest drop in price, a launcher company can make of the loss of profits through volume sales and thus make more profit. That is generally true for many other industries of which computers is particularly true, but hasn't been the case for spaceflight.

    I am still undecided if the economic case is prevalent for spaceflight to become much cheaper, and space tourism by itself isn't sufficient to make it happen. Scientific research in space gets it much closer to closing the business case, but not quite.

Which by the way the report on the WB-8 testing is due at the end of this month, to get funding for WB-8.1 http://en.wikipedia.org/wiki/Polywell

    I'd even go so far as to say if the Polywell doesn't pan out, we're screwed for fusion power. I have very little confidence in a multi-decade multi-billion dollar boondoggle political showboat project

    that's wrong, even in the center of the Sun each cubic meter of material produces energy on the order of a candle, that's how very hard H-H fusion is to do and how rarely it occurs under the most extreme of conditions of pressure and density. We'll never use H-H fusion, it's only for stars. What we have done is D-T fusion at huge energy loss.

    I think the cost per pound is several orders of magnitude cheaper than you are suggesting, but I admit it is still very expensive to pull something from the Moon and bring it to the Earth. The question there is in terms of how cheap can you make a bulk good transportation system (you don't have to worry about squishing something organic, so you can be rough with it) that can make it to the Earth.

    He3 prices right now, on the open market from terrestrial sources, are about $4,000 per gram, or about $100,000 per ounce. That at least is a legitimate target for a business case and if you can get the transportation costs cheaper than that price including extraction costs. That is why it is something being talked about specifically as a profitable venture for a mining operation. Even at that price, there are organizations and businesses who will pay that kind of price for the substance, so it isn't completely out of the question. That is the price if it is used as a refrigerant.

    If practical controlled fusion reactors ever get produced, it is possible that the value of He3 could soar to millions of dollars per ounce essentially closing the business case completely simply due to increased demand. Yes, it is something that is practical, and I'm pointing out an existing application that does not require fusion to even work and still can at least be marginally profitable even if you extract it on the Moon and bring it to the Earth in relatively modest quantities.

    Fusion power won't give you enough specific impulse to get to the stars on a reasonable amount of fuel and within a reasonable time.

    Assume a target speed of 0.1c, and an exhaust velocity of 1000 km/s for a fusion rocket, then you get a fuel/payload ratio of 1/exp(-30000/1000) = 10 trillion, and it will take a lifetime to reach the nearest star.

    So, you'll have to fly much slower, so 0.01c, which will bring the fuel/payload ratio down to a more manageable factor of 20. Of course, you'll want to slow down when you get there, which means a total delta-v of 0.02c, and your fuel/payload ratio goes back up to 400, and your travel time is measured in centuries for the nearest star.

    Assuming that the trip would be one way is a bit much. I doubt it would be allowed to happen at all, not least because it would become an open-ended and mission that could easily cost billions more than first projected if things go wrong an a rescue or emergency re-supply mission is required. There will have to be some collaboration with various space agencies too (for experience if nothing else) and I doubt they would go along with a one-way trip.

    So they need to develop a lander that is capable of taking off again and returning to a service module. Gravity on Mars is much higher than on earth and there is a thin atmosphere, so much more fuel and bigger engines are required, and the lander will have to be of heavier and more durable construction.

    Most of these benefits can be obtained by mining asteroids. The downside is that they're (mostly) further away ; the upside is that they're not at the bottom of a significant gravity well. As an additional upside, we'd get practice at moving and/or manipulating asteroids. We don't know when we'll need that hands-on experience, but it's a certainty that one day our species will really need to know how to move asteroids.

    Once we've got the issues of radiation protection, long-term power supplies (i.e., nuclear) and living in and maintaining a truly closed ecology solved ... the only thing between us and the stars is the psychology of building and manning generation ships. Suspended animation techniques might help there but they're not essential, so if they remain fiction that's not a show stopper.

    A thousand-year long exploration expedition to Alpha Centauri might sound incredible today, but such a project would look very different to a family returning from a 10-year mining contract in the Kuiper Belt.

    It's very unlikely that we're the only life in the universe, and I think that it's unlikely that we're the only intelligent life in the universe (but out of deference to Conway Morris, I do have to entertain the idea) ; but the galaxy could be ours before our species is a half-million generations old. (Actually, we'd speciate, I'm almost certain ; whether deliberately by genetic engineering or incidentally by founder-effect and drift is moot ; probably both.)
