A Canadian team competing to win the $10 million X-Prize announced that they had completed a major milestone on their entrant, the Canadian Arrow. The team performed a successful test burn of their prototype engine and believe it will now work in actual flight – a main engine test could happen as early as August. Twenty one teams from 5 countries are competing for the X-Prize, which will award $10 million to the first group able to launch a three-person rocket twice in two weeks to an altitude of 100 km.
