Musk Jab at Rival Shows U.S. Space Reliance on Russia

Two companies vying with SpaceX for a NASA commercial crew program – Boeing(BA:US) and Sparks, Nevada-based Sierra Nevada Corp. – - may also find themselves relying on Russian engines, because of their plans to use Atlas V rockets, said Marcia Smith, a former director of the space studies board at the National Research Council and now editor of Arlington, Virginia-based spacepolicyonline.com. Even so, mutual dependencies in space may make this one area that’s immune to disagreements on the ground. “The Russians are making money off these sales,” said Marco Caceres of the Fairfax, Virginia-based Teal Group. “It would make sense from a political standpoint to snub us, but from a financial standpoint, it’s not so good.”
