The US SpaceDev company has successfully test fired its new orbital Manoeuvring and Transfer Vehicle (MTV) engine.

There will be three MTV models, weighing 25kg (55lb), 50kg and 100kg designed to perform on-orbit rendezvous for inspection, repair and refuelling. The larger version will be used for supply missions to the International Space Station.

The MTV programme is part funded by the National Reconnaissance Office and the US Air Force.
