Having Rep. Gabrielle Giffords (D-Ariz.) at the launch of her husband's space shuttle flight is symbolic of the "triumph of good over evil," NASA Administrator Charles Bolden said on Monday.

"It will be incredibly special to have Gabby at launch because, to me, it represents the triumph of good over evil," Bolden said at a Senate Appropriations Committee. "So I think it's incredible for the country if she's able to make it."

"I wear a bracelet for Gabby because she's a personal friend," he said while fighting back tears.

Giffords's husband, Capt. Mark Kelly, is slated to command the the Space Shuttle Endeavour's final flight.

The congresswoman, who suffered a gunshot wound to the head during a shooting rampage in January, is recovering at TIRR Memorial Hermann Hospital in Houston. Last week her office said she would attend the launch, scheduled for April 29, if her doctors OK it.

Her doctors have said that Giffords continues to recover and is increasingly regaining movement ability and requires comparably less assistance.
