Former X Prize Rivals Announce Partnership

Two former rocketeer rivals are teaming up to develop privately-built spacecraft, officials with both groups said Friday. Canada's London, Ontario-based firm PlanetSpace and the Romanian aerospace company ARCA - both past competitors in the $10 million Ansari X Prize contest for suborbital spaceflight - are pooling their expertise or a joint space project. While some details of the partnership remain under wraps, the collaboration will likely include the sharing of technology and other resources, PlanetSpace officials said.
