Outlook for low-cost satellite launchers.
SpaceX has made a breakthrough in satellite-launcher technology, with the successful recovery of a first-stage rocket involving a soft landing. SpaceX is challenging other launcher companies with a new business model that promises deep cuts in the cost of gaining access to space. This could transform the economics of space applications in near-Earth orbit communications and other space-based services.
Some of the potential gains of cheap launch vehicles may require the development of more exotic technologies.
Reaction Engines aims to reduce the cost of payload carried directly to low orbit to 1,000 euros (1,090 dollars)/kilogramme, from 22,000.
A viable hypersonic vehicle is unlikely to be available before 2030.
