World sends words of sorrow as US mourns shuttle crew
The world's other major space power, Russia, sent its condolences to Washington, but yesterday went ahead with the launch of a cargo rocket carrying food and fuel to the International Space Station (ISS).
The seven members of Columbia's crew had "given their lives to conquering the dangers of space in the name of peace, science and progress of civilisation", Russian President Vladimir Putin said of Saturday's tragedy.
