BBC: A revolutionary UK space plane design was recently evaluated by the European Space Agency. In their report, the agency’s experts concluded that “no technical or economic impediments have been identified” that would prevent the project from going forward. Skylon is a proposed hybrid reusable aircraft that would do the job of a big rocket but operate like an airliner, taking off and landing at a conventional runway, writes Jonathan Amos for the BBC. The aircraft would use a combined-cycle, air-breathing jet engine to reach orbit with only a single state. Whereas the price for launching a kilogram of payload into geostationary orbit is currently more than $15 000, Skylon could bring that down to less than $1000, claims its manufacturer, Reaction Engines Limited.
