Commercial Launch Demand to Private Microgravity Habitats at Low Earth Orbit

A 2018 Pew Research poll suggest that 42% of Americans would be interested in traveling into space. But, so far, only seven super wealthy individuals have been able to do so with their own private funds. Multimillionaire Dennis Tito was the first tourist to travel into space to the ISS. Billionaire Charles Simonyi was the first space tourist to pay for  two trips to the ISS.

The Russian space agency has charged these super wealthy individuals between $20 million to $40 million to travel to the ISS. And because of the extraordinarily high cost of space travel,  space tourism has been exclusively for the super wealthy.

Bigelow Aerospace is currently offering tickets to the ISS for $52 million each for a one to two month stay at the International Space Station. 

There are over 2100 billionaires on Earth. 52,000 people in the world who are worth over $100 million with 15,000 of those individuals living in the US alone. So there are at least 52,000 people on Earth who could afford to travel to a space and to a space station at current prices.

Companies like Bigelow Aerospace have also been developing their own private space habitats that they hope to deploy some time during the next decade. And  NASA has recently presented space habitat concepts from several private space companies including Blue Origin and Lockheed Martin. 

$50 million seems close to the current rate for training, transporting, housing, and feeding a space tourist.  Optimally, you want to protect your customers health, so ten days in space should prevent any noticeable anatomical or physiological health effects. The ten days would include the launch days to the private space station and the return to the Earth's surface. That should give a tourist 8 full days inside of a private space station.  The pre-launch experience should also include astronaut training with maybe a few hyperbolic flights aboard a jumbo jet to test the individuals reaction to brief periods of microgravity and dynamic flight situations.

Once inside of the orbiting space habitat, a paying tourist should be given spacious-- private quarters-- for sleeping, bathing, communicating with friends and family back on Earth and watching network and cable television programs or videos and movies on a private wide screen monitor. 

A large microgravity recreational area should also be available for guest. And the recreational area should be at least as spacious as the accommodations  experienced by astronauts aboard the old 6.6 meter in diameter Skylab facility. Notional habitats derived from the New Glenn upper stage (7 meters in diameter), Bigelow's Olympus: BA-2100 (12.6 meters in diameter), and SLS propellant tank technology derived habitats (8.4 meters in diameter) should provide spacious environments for microgravity recreational activities.

At least three FlexCraft EVA tours should be available so that guest can experience moving about in space while experiencing spectacular view of the Earth and external views of the  space habitat where they have been residing. FlexCraft would give tourist the advantage of quick and convenient access to space without the need for several hours of pre-breathing oxygen in order to prevent decompression sickness (the bends).  Flexcraft can be flown in space by the tourist or tele-operated by personal on the ground or authorized personal inside of the space habitat. Manipulation arms could also be removed from FlexCraft vehicles that are utilized for tourist.

The commercial spacecraft pilots could serve as the onsite guest service agents for the tourist they've taken up to the space habitat. Robots operated by personal on Earth could be used by the space habitat owners to assist the pilots and their guest-- even on FlexCraft EVAs. 

If the polls are correct then their should be at least  6300 super wealthy Americans who desire to travel to a space station-- and can afford to do so. And if there is a similar statistical desire  world wide, then there should be  at least  22,000 super wealthy people who want to travel into space-- and can afford to do so.

Annually, if just 10% of the super wealthy who desired to travel into space (2200 people)-- did so-- that would require 440 to 550 private commercial launches every year. In 2018, there were only 111 successful space launches with only four them being crew launches. So space tourism should create dramatic increase in the launch rate accompanied by substantial reductions in launch cost. But even if it were only 1%, that would require 44 to 55 private commercial launches every year.

But what if there was a national or even an international lotto system that could allow private individuals to risk an American dollar for a chance to travel into space? What if  42% of adult Americans risked $5 a year, on average, for a chance to travel into space through a Space Lotto system?  That would generate approximately $1.2 billion a year for crew launches. And that would be enough money to send 24 average Jane's and Joe's into space every year (5 to 6 additional crew launches).

But you could add even more incentive for Americans to purchase Space Lotto tickets if winners were given a monetary prize of $250,000 (less than 1% of the cost for the round trip ticket to space). Winners could be given $125,000 initially for their time off from work for astronaut training and traveling into space. An additional $125,000 would be given to them once they returned from space.

 If 42% of the world's adult population were willing to participate in Space Lotto system with a similar financial reward but only risked $2 per year, that would still generate $5 billion a year. That could purchase enough tickets for 100 winners per year (20 to 25 additional crew launches).

Optimally, a single private space habitat might be able to accommodate 36 tourist flights per year for a 10 day stay. Ten habitats would be required to accommodate 360 flights per year. So, obviously, there would also be a significant launch demand just to deploy the private habitats needed to accommodate potential tourist.
