Russia has denied that a missile test that destroyed an orbiting satellite endangered the crew on the International Space Station (ISS). U.S. officials said Monday the missile hit an old Russian satellite, which burst into more than a thousand pieces. They said this debris thrown into orbit at about 28,000 kilometers per hour could cause major damage to the ISS. The American space agency NASA said all seven members of the ISS crew were directed to seek safety in their spaceship capsules for two hours. The crew includes four American astronauts, a German astronaut and two Russian cosmonauts.
