UK spaceplane shoots for 2020 flight test ....


An Oxfordshire company's bid to transform transportation to orbit with a radical air-breathing rocket engine it claims will be capable of driving airline-style operations with a runway take-off and landing reusable spaceplane got a shot in the arm last week in the form of £60 million ($91 million) from the UK government.

The key to SABRE - Synergetic Air-Breathing Rocket Engine - is a heat exchanger, essentially a radiator made of many hundreds of kilometres of 1mm tubing, which is capable of liquidising oxygen from intake air by boiling off tanked liquid hydrogen and, critically, not frosting up in the process.

Le ambizioni spaziali britanniche messe in ombra dall'annuncio del finanziamento al progetto SABRE ....


UK Space Conference: Air-breathing rocket takes the headlines but it is the size of UK space ambition that is the most breathtaking ....


The big announcement of the conference was made by the UK Government, via its Science minister David Willetts MP.

It is to fund the next phase of the development of Reaction Engines' SABRE air-breathing rocket engine to the tune of £60 million ($91 million).

Willetts himself continues to hope that ESA will continue to support the Reaction Engines project and provide actual funding for the engine prototype building phase.

Willetts jestfully noted to ESA's head Jean-Jacques Dordaine to that while Ariane rockets were the present, Skylon was the future.

Government to invest £60 million in world’s first air-breathing rocket engine ....


Through the UK Space Agency, the Government is set to invest £60 million in the development of the SABRE - a British-designed rocket engine which could revolutionise the fields of propulsion and launcher technology, and significantly reduce the costs of accessing space.

ESA asks Reaction Engines to study Skylon as Europe’s next generation launch vehicle ....

While the French and Germans continue to bicker over the final configuration of Ariane 6 even though it has been officially set, the European Space Agency is now looking beyond that rocket.

DARPA To Start Reusable Launch Vehicle Program ....


DARPA is about to start a program to develop a reusable first stage that could be used to launch medium-sized satellites for as little as $5 million each.

Speaking at the AIAA Space 2013 conference here Sept. 12, Pam Melroy, deputy director of DARPA’s Tactical Technology Office, said the agency would release a Broad Agency Announcement in the next few weeks for a program called Experimental Spaceplane, or XS-1.

An industry day for the program is planned for early October.
