Victory in the heights

Soaring above 50 miles high in a beauty of a vessel, the age of space tourism began. The Unity-22 flight by Virgin Galactic, with a British pilot and British passengers, opens a new era, not just for multi-millionaires who can afford the experience, but for options for spaceflight in general.

Yes, Blue Origin will be coming along later, and their New Shepard is a most brilliant machine, but it does not swoop out across the sky and glide home with the elegance of a swallow, as Branson’s did. Virgin Galactic has built an aeroplane to space.

It was a very Branson occasion. The flight was short, the presentation glitzy, with a rock band plying for the crowds, whoops and cheers, and a presentation reminding us of all the other Virgin-branded endeavours Richard Branson is leading – including his investment in Elon Musk’s hyperloop.

For those who have followed the career of Burt Rutan, Spaceship Two, of which Unity is the one flying example at them moment, is unmistakably his: it has his familiar curves all over it and crowns a most remarkable life of aircraft design. (That said, he has not stopped, even in retirement.)

It shows us how things have changed. This is not the X-15 rocket-plane, with a pilot cramped inside a cabin barely big enough to move his arms, fighting to keep control of a wayward machine – Unity has a passenger cabin with comfy seats, lounge room, yet it flies as high and as fast as the X-15.

Up until now, we have always had astronauts who were carefully chosen men, the best pilots entrusted with the fasted aircraft, young and trained to the peak of fitness, as they had to be so as endure being confined in a narrow box, to endure the crushing forces of blast-off on a converted ICBM, and to keep exact control of a tumbling capsule. Now we have Richard Branson, fit perhaps but 70 years old, stepping from the spacecraft at the end without showing any discomfort. That is a great achievement.

Jeff Bezos will be taking an eighty year-old lady, a veteran pilot: that too shows how far rocketry has come.

The key element of both Spaceship Two and New Shepard is 100% reusability. Spaceship Two is a spaceplane and New Shepard a vertical rocket, two very different concepts. There is room for each, and for SpaceX, which will take passengers even into orbit. The idea of a spaceplane is to use up the fuel in the ascent, and then glide back to Earth empty, while for a reusable rocket there are no wings, which reduces friction but requires the vessel to keep much of the propellant ready to relight the engines for a controlled descent.

Space for everyone is in reach. There has been talk of taking Tom Cruise to the International Space Station just to film a scene for a Mission Impossible film: that would have been inconceivable before Elon Musk made it a reality.

Will Virgin Galactic put paying passengers into orbit? They have put satellites into orbit. After yesterday, it is only a matter of time before customers are taken on orbital flights, and whether they will beat Blue Origin I do not know.

The years ahead of us will be exciting.

One thought on “Victory in the heights”

  1. After the governor, colonial government was broken down into two main divisions: the council and the assembly. The council was essentially the governor’s cabinet, often composed of prominent individuals within the colony, such as the head of the militia or the attorney general. The governor appointed these men, although the appointments were often subject to approval from Parliament. The assembly was composed of elected, property-owning men whose official goal was to ensure that colonial law conformed to English law. The colonial assemblies approved new taxes and the colonial budgets. However, many of these assemblies saw it as their duty to check the power of the governor and ensure that he did not take too much power within colonial government. Unlike Parliament, most of the men who were elected to an assembly came from local districts, with their constituency able to hold their elected officials accountable to promises made. An elected assembly was an offshoot of the idea of civic duty, the notion that men had a responsibility to support and uphold the government through voting, paying taxes, and service in the militia. Americans firmly accepted the idea of a social contract, the idea that government was put in place by the people. Philosophers such as Thomas Hobbes and John Locke pioneered this idea, and there is evidence to suggest that these writers influenced the colonists. While in practice elites controlled colonial politics, in theory many colonists believed in the notion of equality before the law and opposed special treatment for any members of colonial society.
