    The Skylon design omits infrastructure such as booster rockets and external fuel tanks, which should keep the cost of the project down in comparison with traditional spacecraft. Additionally, the craft will take off and land on a conventional runway, avoiding the expense of dedicated launch facilities.

    Once it has completed its mission, Skylon can re-enter the Earth's atmosphere and land like a traditional aeroplane. Ths means it can be prepared for another mission within a short time frame.

    Re-entry occurs approximately 10km higher than the space shuttle. The temperature on re-entry is kept down to 1100 Kelvin (K) by dynamically controlling the trajectory based on feedback from external surfaces.

    "Skylon differs from other spaceplane configurations in several key respects," the ESA said in its report. "Apart from the unique propulsion system, the main difference is an aerodynamic configuration that comprises a definite wing plus body. This was selected because it proved to be more optimum in terms of weight, lift and volume than the more fashionable blended bodies frequently portrayed for spaceplanes."

    The ESA's assessment was made up of two parts. The first was a series of visits made by the ESA to review the designs and witness critical component testing. The second was the system requirement review — which took place in September 2010 — during which more than 100 international aerospace experts reviewed the technical and economic feasibility of the plans.

    The next phase of testing will conclude in 2012. This will involve working trials of some aspects of the technology, including a demonstration of the pre-cooled engine with frost control air intake, as well as a re-assessment of the implementation and operational issues of the Sabre system.
