Space Station Crew Locked Themselves As Russia Tested Anti-satellite Missile

The United States expressed its concerns over the space debris generated from Russia's anti-satellite missile test on November 15. After the test, NASA advised the seven-member crew of the International space station to lock themselves in their docked spaceship capsules for two hours. ''We'll continue monitoring the debris in the coming days and beyond to ensure the safety of our crew in orbit,'' said Bill Nelson, NASA chief.
