The three crew members at the International Space Station were today said to be grieving after they were told about the Columbia disaster by a Nasa official.

Charred human remains have been found among the debris from the stricken space shuttle Columbia.

One focus of attention in the investigation into the tragic loss of the space shuttle Columbia is possible damage to its protective thermal tiles on the left wing from a flying piece of debris during lift-off on January 16.
