TECHNOLOGY: Virgin Galactic-The First Commercial Spaceflight Company at a Glance



TECHNOLOGY: Virgin Galactic-The First Commercial Spaceflight Company at a glance 
By Jorge Jefferds November 7, 2014 

On October 31st, at 10.51am PST, Spaceship Two crashed to Earth after experiencing an in-flight anomaly. The flight was the first test of Spaceship Two with new plastic-based fuel, replacing the original—a rubber-based solid fuel that had not met expectations. The crash caused one fatality and one serious injury.

When we all heard these news, we didn’t become surprised at all, just thinking it was one of the many unsuccessful launches NASA performed.  However, the accident affected a different sector of the space industry; this time, Virgin Galactic, the pioneer company in commercial spaceflights.

Founded in 2004, the first and most important mission was to design and manufacture a privately funded vehicle that could deliver the weight of three people (including one actual person) to suborbital space.

The vehicle had to be 80 percent reusable and fly twice within a two--week period. Spaceship One was born to fulfill the initial tests in 2004. With this success, the Virgin Group licensed Mojave Aerospace Venture’s technology and invested in the development of a second-generation vehicle for commercial purposes. Currently, for Tourism Experiences, the spaceline owns and operates a space system consisting of two vehicles, Spaceship Two and White Knight Two.

The planned trajectory would achieve a suborbital journey with a short period of weightlessness. Carried to about 16 kilometers, or 52000 ft, by the 'buddy' aircraft, White Knight II, after separation the vehicle would continue to over 100 km (the Karman line, a common definition of where “space” begins). The time from liftoff of the White Knight booster carrying Spaceship Two until the touchdown of the spacecraft after the suborbital flight would be about 2.5 hours.


Spaceship Two, Virgin Galactic’s primary space vehicle, is designed to reach an altitude that exceeds NASA’s definition of space and earns the potential customers official astronaut status. Passengers will experience the unique thrills of spaceflight, enjoying the opportunity to leave their seats to float in zero--gravity for six minutes.

Looking out through twelve large windows, passengers will take in astounding views of space and of the Earth below, stretching approximately 1,000 miles in every direction. Prior to the flight, passengers will go through three days of preparation, medical checks and bonding with their flight crew–all of which is included in the Price of the space ticket.

A Virgin Galactic suborbital flight for an individual costs $250,000. To date, the company has received more than $89 million in deposits and sales from approximately 700 individuals (20% more than the total number of people who have ever gone to space). Among them, famous people like Stephen Hawking, Tom Hanks, Lady Gaga, Ashton Kutcher, Katy Perry, Brad Pitt, and Angelina Jolie, already made their reservations.

In Addition to a Virgin Galactic direct reservations facility, a specialist network of Virgin Galactic Accredited Space Agents has been set up around the world to provide a localized reservation service.

Virgin Galactic will also market Spaceship Two for suborbital space science missions and market White Knight Two for “small satellite” launch services. It had planned to initiate RFPs for the satellite business in early 2010, but flights had not materialized as of 2014.

Private space flights for the rich are far from being completed, but they will not become another unsolved failure. On the contrary, As George Whitesides, Virgin Galactic’s chief executive, pointed out in an interview that took place before the crash, there have been around 100 space-launch vehicles in history. A handful of rocket planes, though, of which only two (the Space Shuttle and the X-15) have flown in space with anyone on board. New technology is always tricky to master; new rocket technology can be some of the trickiest of all.
