Giffords' husband Kelly to lead space shuttle mission

The husband of the US congresswoman injured in an Arizona gun attack will lead one of the final space shuttle missions in April, Nasa has said.

Gabrielle Giffords' husband Mark Kelly will resume training as Endeavour's commander on Monday.

Ms Giffords is having rehabilitation therapy in Houston after being shot in the head in January.

Mr Kelly refused to go into details about his wife's condition but told reporters she is "improving every day...much quicker than the doctors expected".
