This article describes a launch vehicle development roadmap that uses only proven technology and that could lead to a thousand-fold reduction in the cost of sending people to orbit within about 15 years. It could reduce the cost of the first lunar base by very approximately ten times. This would clearly revolutionise spaceflight and create a new space age. The roadmap involves a combination of full reusability, aeroplane-like vehicle design and high traffic levels, especially from space tourism, to provide economies of scale. This line of development could have started some fifty years ago, and the failure to do this has led to a corporate groupthink that is probably now the biggest obstacle to progress.
