Back to work Monday for Congresswoman Gabrielle Giffords' husband.  Astronaut Mark Kelly resumed training for his planned space shuttle mission in April.

Kelly and his five crew-mates are slated to launch aboard Endeavour on April 19 for a two-week mission to the International Space Station. 

Kelly said it wasn't an easy decision to go back to work.

He expects his wife to be at the launch.
