However, orbital space tourism is a relatively low-volume niche market at the moment, with uncertain prospects. The more routine (or perhaps even despised) it becomes, the less it is [[a world worth talking about]], which is a precondition for any real economic opportunity. It currently depends on transportation and accommodation shared among space-faring super-powers with sometimes-difficult relations. CATS must be enabled by some new market that increases launch demand significantly, and the world's rich and highly adventurous are not likely to do that. Project Persephone aims to explore the recreational possibilities that orbit might offer to "the rest of us" who are earthbound, as well as what sort of economic opportunities those recreations could open up for people in the developing world.

Most users of comsat services consider them reasonably priced.  However, that's because those users can (by definition) afford them. Even if one considers satellite communications a kind of "access to space", it is not cheap for the world's poor.  In 1994, MCI executive [=Greg LeVert=] notoriously claimed that half the world had yet to place a phone call.  [^[[http://en.wikipedia.org/wiki/Clay_Shirky | Clay Shirky]], [[http://www.shirky.com/writings/half_the_world_old.html | Half the World]], June 30, 2002^] That was probably not true even then, but the number of phoneless world citizens might still be as high as 25% as of 2010.  In places like southern Somalia, a satellite TV broadcast of a soccer game in Europe is more likely to be seen in a movie theater than at home. People there can afford some recreational "access to space" in some expanded sense, though it will be only occasional, temporary, shared, one-way, and indirect.

Although [[Project Persephone]] will help make comsat-mediated access cheaper, at least as a side benefit of promoting space development in general, that's not the Project's main direction. Wherever terrestrial communications options are cheaper than orbital ones, it will use them. Communicating ''through'' a piece of equipment in orbit will not, in itself, promote space development very much. For one thing, cheaper terrestrial substitutes continue to make inroads on the communications market. For another, improvements in comsat technology are reducing the amount of electronics to be orbited, which (all other things being equal) reduces launch demand and therefore helps to keep launch costs high.

Consider what might be called "U-Turn Space Access" -- [[satellite communications | communications satellite]].  Is a satellite TV dish antenna providing "access to space"?  Yes, albeit one-way and indirectly.  It provides access, through space (as a communications medium), to a resource in space: the satellite.  What about a long-distance call that goes through a satellite link?  Insofar as it actually causes something to happen (however briefly) in the satellite itself, and must provide real-time (two-way) response, it's somewhat more direct.  But it's also more expensive because of that.

Since [[http://en.wikipedia.org/wiki/Dennis_Tito | Dennis Tito]]'s landmark voyage to [[ISS]] on a Soyuz in 2001, [[orbital space tourism]] has stoked hopes for a significant recreational market for orbital adventures. [[http://en.wikipedia.org/wiki/Anousheh_Ansari | Anousheh Ansari]]'s major contribution to the [[http://en.wikipedia.org/wiki/Ansari_X_Prize | X Prize]] purse pushed the idea of [[suborbital space tourism]] toward realization. For the foreseeable future, however, such recreations will not be affordable for any but the richest citizens of developed nations. The prospects for the less wealthy to get a chance to work in space, to cover the costs of transportation to orbit and a life in flight, are hardly better.  Progress in space robotics (both [[telebots | teleoperated]] and autonomous) might even mean that opportunities for astronautical and mission-specialist careers will begin to dwindle. If economies of scale are the solution to high launch costs, the problem of how to get higher scale is not likely to be solved by sending more people.

Geosynchronous orbital slots probably come closest to our ordinary sense of a "place" beyond Earth, short of going to a planet. Such slots are akin to property, as they are directly above places on Earth, and have legal assignees. If the area around the equator can be considered a single (circular) "place", low equatorial orbits might also be considered "places in space", since spacecraft in those orbits fly over that terrestrial band.

If you define "access" as going to space, or putting things there, ''cheaper'' access would be a more realistic way to express the goal. Some launches look cheap, but looks can deceive.

In the longer run, however, enhancing the benefits of space access, and particularly increasing the benefits of personal involvement, will depend on making physical access cheaper. This will almost certainly require a fairly dramatic increase in the demand for such access -- i.e., making space launch cheaper through economies of scale, both in vehicle/payload manufacturing and in launch operations. Rocket launch is not something that can divided so finely, however. Each launch is an event, and often a big one. It has been repeatedly argued, in fact, that bigger is better, at least for rocket launch.[^See, for example, John Jurist, Sam Dinkin, David Livingston, [[http://www.transterrestrial.com/archives/When%20Physics%20Economics%20and%20Reality%20Collide.pdf | "When Physics, Economics and Reality Collide: The Challenge of Cheap Orbital Access]]", American Institute of Aeronautics and Astronautics, AIAA-2005-6620 (Sept 2005)^]

Space is different things to different people.

Counterintuitive "long-way-around" orbital dynamics means that if you want to [[http://en.wikipedia.org/wiki/Orbital_inclination_change | change orbital planes]], but still stay at the same altitude, it makes sense to first go further up, then change direction, then fly back down (which, also somewhat counterintuitively, means expending as much energy as used on the way up.)

Consider a broad definition of "access" that includes access to benefits -- even for beneficiaries who don't necessarily realize that the benefits are coming from orbit. One way to reduce space access costs per person (a very indirect way, and not personally very involving for most beneficiaries) is to divide these conventional benefits more finely and distribute them more widely -- as is often the case for [[http://en.wikipedia.org/wiki/Remote_sensing | remote sensing]] missions. There is a Project Persephone effort that follows this strategy, specifically by first focusing on the humanitarian benefits of remote-sensing satellites in low equatorial orbits, potentially yielding lessons for the design of satellite missions in other orbits. This effort is very much in line with the Project's goal of [[meeting the SPEC]].

Consider a broad definition of "access" that includes access to benefits -- even for beneficiaries who don't realize that the benefits are coming from orbit. One way to reduce space access costs per person (a very indirect way, and not personally very involving for most beneficiaries) is to divide these conventional benefits more finely and distribute them more widely -- as is often the case for [[http://en.wikipedia.org/wiki/Remote_sensing | remote sensing]] missions.

to make going to space cheap, but rather to make space ''more'' accessible, ''more'' affordable, to produce more value, for more people, for the large amount of money spent.

[[Project Persephone]] aims to bring the benefits of space development to more people, particularly people in some of the poorer places in the world. Making space access cheaper per person can help. One way to do this is to divide the conventional benefits more finely and distribute them more widely. There is a Project Persephone effort taking that approach, specifically by first concentrating somewhat narrowly on the humanitarian benefits of remote-sensing and communications satellites in [[LEO | low Earth orbit]] around the equator, to see if the lessons learned from those missions might extent to the design of similar satellites in other orbits.

Making space access cheaper in the long run, however, will depend
on making physical access cheaper. This will almost certainly require an increase in the demand for physical access to space -- i.e., cheaper space launch through economies of scale in manufacturing and launch operations. Rocket launch is not something that can divided so finely, however. It has been repeatedly argued that bigger is better, at least for rocket launch.[^John Jurist, Sam Dinkin, David Livingston, [[http://www.transterrestrial.com/archives/When%20Physics%20Economics%20and%20Reality%20Collide.pdf | "When Physics, Economics and Reality Collide: The Challenge of Cheap Orbital Access]]", American Institute of Aeronautics and Astronautics, AIAA-2005-6620 (Sept 2005)^]

To clarify matters, let's be sure we understand the range of meanings for "cheap" and for "access". These will depend, after all, on where you stand and what you want. For that matter, regarding space as a single place is conceptually suspect. For example, changing orbits can be very expensive. And different orbits have different uses. Using a larger rocket to get to space more cheaply may limit the choice of orbits you can reach.

For
the foreseeable future, recreational space travel will not be affordable for any but the richest citizens of developed nations. The prospects for the less wealthy to get a chance to work in space, to cover transportation and housing costs, are hardly better.  Progress in space robotics (both [[telebots | teleoperated]] and autonomous) might even mean that opportunities for astronautical and mission-specialist careers will dwindle.

Although [[Project Persephone]] will work to make comsat-mediated access cheaper, at least as a side benefit of promoting space development in general, that's not the Project's main direction.  Wherever terrestrial communications options are cheaper than orbital ones, it will use them.  Communicating ''through'' a piece of equipment in orbit will not, in itself, promote space development very much.  Cheaper terrestrial substitutes continue to make inroads on the communications market, for one thing.  For another, improvements in comsat technology are reducing the amount of comsat equipment to be orbited, which (all other things being equal) reduces launch demand and therefore keeps launch costs high.

Although
[[Project Persephone]] will work to make this kind of comsat-mediate U-turn Access to Space more affordable, at least as a side benefit, that's not the Project's main direction.  In fact, wherever terrestrial communications options are cheaper than orbital ones, it will use them.  Communicating ''through'' a piece of equipment in orbit will not, in itself, promote space development very much.  Cheaper terrestrial substitutes continue to make inroads on the communications market, for one thing.  For another, improvements in comsat technology are reducing the amount of comsat equipment to be orbited, which (all other things being equal) reduces launch demand and therefore keeps launch costs high.

No, if anything

''Cheaper'' access would be a more realistic way to express the goal.  For most people on Earth, going into space will probably never be affordable as a recreation.  Progress in robotics (both [[telebots | teleoperated]] and autonomous) will probably mean that working in space to cover transportation and housing costs in space will be only for the very few (and very skilled) who must be actually be present.  Rather, the CATS challenge is to make space ''more'' accessible, ''more'' affordable, to produce more value, for more people, for the large amount of money spent.

"Cheap" is also relative to one's purchasing power.
  Consider what might be called "U-Turn Space Access" -- satellite communications.  Is a satellite TV dish antenna "access to space"?  Yes, albeit one-way and indirectly.  It provides access, through space, to an orbital resource.  What about a long-distance call that goes through a satellite link?  Insofar as it actually causes something to happen (however briefly) in the satellite itself, and must provide real-time response, it's somewhat more direct, but it's also more expensive because of that.

Most users of comsat services consider them pretty cheap
.  However, that's because those users can afford them.  Even if one considers satellite communications a kind of "access to space", it is not cheap for the world's poor.  In 1994, MCI executive Greg LeVert said that half the world had yet to place a phone call.  [^http://www.shirky.com/writings/half_the_world_old.html^]  That's probably not true anymore (assuming it was true even then), but it might still be as high as 25% as of 2010.  In a places like southern Somalia, a satellite broadcast of a soccer game taking place in Europe is more likely to be seen in a movie theater than anywhere else.  They can usually afford only occasional, temporary, shared, one-way, indirect access to space.

Although [[Project Persephone]] will work to make this kind of comsat-mediated access cheaper, at least as a side benefit
of promoting space development in general, that's not the Project's main direction.  Wherever terrestrial communications options are cheaper than orbital ones, it will use them.  Communicating ''through'' a piece of equipment in orbit will not, in itself, promote space development very much.  Cheaper terrestrial substitutes continue to make inroads on the communications market, for one thing.  For another, improvements in comsat technology are reducing the amount of comsat equipment to be orbited, which (all other things being equal) reduces launch demand and therefore keeps launch costs high.

The problem is how to sustain, and increase, the demand for putting things in space.  Having wealthy customers for [[orbital space tourism]] right now is helpful -- it redistributes wealth in a way that sustains and promotes space development, and helps make it cheaper for others coming along later.  But orbital space tourism is a somewhat uncertain, relatively low-volume niche market for the foreseeable future, not least because it currently depends on government space transportation and accommodation shared among space-faring super-powers with difficult relations.  CATS can only be made possible by a new market that increases launch demand significantly

!!! Facing Inescapable Realities

->''We can judge our progress by the courage of our questions and the depth of our answers, our willingness to embrace what is true rather than what feels good'' - Carl Sagan

Project Persephone's agenda grows out of several conclusions about what it will take to bring space access costs down to Earth: future space applications must meet the criteria of ''being commercially attractive'', ''involving a large user base'', ''fostering (but not requiring) human presence in space'', and ''being environmentally sustainable''.  In more detail:

* '''Be commercially attractive'''

-> Only some new, growing market will increase launch rates.  Higher launch rates are key to fostering the economies of scale (in production and operation) required to spur investment in lower-cost, higher-volume space launch infrastructure.  [[Orbital space tourism]] remains a recreation for the few who are motivated enough go through astronaut training, brave enough to take the trip, and rich enough to afford it.  It has been hosted so far only via governmental space programs (Russian manned launch, [ISS]].)  The market for [[suborbital flight]] looks promising, but remains somewhat speculative; if successful, it may whet appetites for orbital tourism, but the technologies involved for suborbital flight do not go far toward solving the much more difficult problem of low-cost ''orbital'' space access.  Something new is needed.  And it has to be popular.

* '''Involve a large user base'''

-> This may be a prerequisite for being commercially attractive.  Enthusiasm for space development is naturally limited when only a very few can experience the rewards of participating directly.  Expansion of activities in orbit must compel the attention of a large user base consisting of individuals, teams and organizations with relatively small budgets, limited time and energy, and limited skills and qualifications.  Popular activities must be designed that allow people on Earth to visibly make things happen in space; to do things on Earth that enable present and future space activities, including more manned space travel in the long run; and to communicate effectively and enjoyably about what they are doing, what they have accomplished, and what they want to do next.

* '''Foster -- but don't require -- human presence in space'''

-> Launching human beings into orbit and returning them safely to Earth will entail very high costs for the foreseeable future.  Yet, public and private investment in this adventure proceeds apace.  Future activities should (among other goals) be oriented toward making space more habitable for human beings in the long run; adventurous manned space programs (both governmental and private sector) should be not be denigrated.  However, no work should be undertaken by the organization if the activity ''requires'' sponsoring human presence in space.

* '''Be environmentally sustainable'''

-> Space is not the ultimate environmental escape hatch; rhetoric aimed at selling space access that way is easily seen as alarmist, and sometimes seen as transparently elitist, since the lifeboat would necessarily only be for the few.  Activities should therefor minimize the degree of environmental degradation necessary for success, and should emphasize long-term (multi-century) improvements in living standards globally.  They should improve, in the near- and medium-term, the living standards and ecosystems of localities that host activities, especially those in developing nations.  Sustainability includes minimizing pollution of the orbital environment with debris, which poses hazards to other useful (and environmentally important) space activities.

Realistically, access to space will probably never be cheap.  The challenge is to make it more accessible.  Is a satellite TV dish antenna "access to space"?  How about a long-distance call that goes through a satellite link?  Even this kind of "ATS" is not "C", for the world's poor.  Someone once said, "half the world has yet to place a phone call."  That's probably not true anymore, but it might still be as high as one-third.

Although [[Project Persephone]]
will work to make that sort of communicative Access to Space more affordable, at least as a side benefit, that's not the Project's main direction.  In fact, where terrestrial communications options are cheaper, it will use them.  Communicating ''through'' a piece of equipment in orbit will not, in itself, promote space development very much.  Cheaper terrestrial substitutes continue to make inroads, for one thing, and improvements in comsat technology are reducing the amount of equipment to be orbited, all other things being equal.

No, if anything, the problem is how to sustain, and increase, the demand for equipment in orbit.  Rich customers going on space adventures now is good -- it redistributes wealth in a way that sustains and promotes space development, and helps make it cheaper for others coming along later
