The Stars: Our Destination

Vacations in space and time

Forty years ago it was “one small step for man, one giant leap for mankind.” Now it is a small step for anyone who dares.
For the last four decades, space flight has been neglected as a primary conduit to human evolution. Popular opinion sees space flight as a sidebar to human development. Even NASA, with their use of aging, decrepit and obsolete shuttles, appears to believe the same. But fear not, for our savior has arrived in the form of a virgin. Well, the Virgin Galactic program that is. Virgin has taken the initiative in commercializing space

The dream of everyday space flight has been around a long time. But, while science fiction has been escalating in the last decade with advanced computer-generated graphics, society has largely forgotten actual space exploration. In the mid-20th century, the United States and the former Soviet Union were feverishly involved in pushing space exploration. It seemed that, like in Star Trek, space exploration was best executed by the government.
In the 1980s, NASA began to launch shuttles that took off from and landed on Earth more than once. These shuttles cut down on the cost of development. The down side of the shuttle, however, was they offered no progression. The need to develop new models was minimal.
Since then, however, the idea of international cooperation has inspired multiple governments to join together and build the International Space Station. Bent on scientific discovery rather than territorial expansion, the station has ended much of the exploration being done by governments. The weight of exploration is now left to the private sector. With little room being left on Earth to expand empires, corporations like Virgin have seized the opportunity to expand their market into space. It offers free expansion as no one currently owns space.
Further initiative came from the Ansari X prize. It inspired innovators and dreamers to build the first commercial sub-orbital space craft. Many competitors strove to reach the goal and win the prize: $10 million. It was a company named Scaled Composites, founded by Burt Rutan, that eventually designed the winner. Named SpaceShipOne, it flew at an altitude of more than 100 kilometres. The design of SpaceShipOne is simple and efficient, which makes it significantly less expensive than NASA’s fuel-guzzling shuttles.
SpaceShipOne uses a form of biofuel. The fuel is practical enough to allow the ship to reach sub-orbit, but requires less than half of what a normal shuttle does. To achieve optimal efficiency, Scaled Composites attached the SpaceShipOne to WhiteKnightOne, an aircraft. Instead of launching from the ground, ShipShipOne launches after becoming airborne. This technique allows for even more efficiency.
The ship’s efficiency was what drew Virgin’s Sir Richard Branson. The company was inspired to begin its own attempts at building a commercially viable passenger space craft. Based on the SpaceShipOne’s design, SpaceShipTwo has become Virgin Galactic’s platform for allowing private citizens to visit space.
“It was Stephen Hawking who first got me thinking about this issue when he explained clearly and concisely to the BBC that mankind had no option but to get to space as quickly as possible and start doing things up there that we have been doing on planet Earth, but in a much more efficient manner,” Branson said at SpaceShipTwo’s unveiling.
Branson seemed sincere when he said that space flight is essential to human development. Without prospects of commercial success, however, Virgin Galactic would be unable to justify their investment to stockholders.
That profit requirement means a ticket to space does not come cheap. Current pricing places the cost of a ticket at $200,000 US a seat. The ticket will buy tourists a several minute journey at sub-orbital altitudes.
Though the initial price of a ticket will prove far out of reach for most consumers, it is expected to incrementally decrease as the program continues to pick up speed. After a few years and a few hundred people, the price of a ticket will most likely go down to $20,000 US a piece.
There are others, however, who are finding a way around paying the hefty fee. A British businessman was able to exchange two million Air Miles points for a ticket aboard one of the first flights. However, for the majority of people, $20,000 is far too expensive, even if it is to witness something as spectacular as seeing planet Earth from space. 
Yet Branson sees this as just the beginning of better things to come for the industry.
“With the end of the oil era approaching and climate change progressing faster than most models have been predicting, the utilization of space is essential not only for communications but also for the logistics of survival through things such as weather satellites, agricultural monitoring, GPS and climate science.”
Not only would space be a reasonable way to guarantee survival of the species, it would also guarantee optimal profit should Virgin Galactic hold a monopoly on commercial space flight. However, without a profit, there would be no motivation for space tourism in the first place.
Several companies, such as Rocketplane Limited, Space Adventures and EADS Astrium, have announced their intention to be commercial spaceflight agencies. There is no doubt that in the future, spaceflight will become a standard of travel.
For Virgin Galactic, however, tourism is just the beginning. The company will most likely expand from tourism to a more lucrative industry like transportation from one side of the Earth to the other. Instead of taking a day to travel to Japan, a spaceship capable of holding up to 100 passengers could cut that time significantly.
The advantages of commercial space flight are numerous. Its ability to push innovation is already taking the place of NASA. Government will always play a role to some degree, but ventures such as asteroid mining, solar energy collectors and colonization will be ideal for corporations to invest their time and money into because of the potential for maximum profit.
Although governments could plan and build environments on other planets to house humans, it would be capitalism that forces the economy and infrastructure. What drives people to exotic places is not just a sense of adventure but, like with any new frontier, the possibility of discovering a better life with better job opportunities. Those jobs will be provided by companies like Virgin.
Relatively speaking, there are still more than enough complications prolonging spaceflight developments. While interplanetary exploration is accepted as a future prospect for mankind, interstellar spaceflight is a bit more complicated with the vast gaps between stars. It would currently take centuries to get to the nearest star systems using the most powerful propulsion methods currently available. Though most of us will not be able to see the interstellar steps, we will be alive to see the first true steps of space exploration.
