The husband of Rep. Gabrielle Giffords (D-Ariz.) said the congresswoman is recovering quickly from her gunshot wound and will soon mourn with the other victims of the January attack.  

"I want the families of all the other victims and the entire Tucson community to know that Gabrielle will soon stand by your side to mourn this tragedy and learn how we can heal," astronaut and Navy Capt. Mark Kelly, the husband of Giffords, wrote in a Facebook post Tuesday.

Kelly said Giffords is recovering quickly from the shot she took to the head during the attack in Tucson, Ariz., that left six dead and 13 wounded. The suspect in the shooting, Jared Lee Loughner, was indicted by a federal grand jury and will be put on trial in Phoenix.

"It is hard to believe that only one month has passed since Gabrielle was shot," Kelly wrote. "The doctors say she is recovering at lightning speed considering her injury but they aren’t kidding when they say this is a marathon process."

But Kelly is still optimistic.

"Gabby’s appetite is back and – even though it’s hospital food – she’s enjoying three meals a day," Kelly continued in the post. "We can’t thank you enough for the heartfelt show of support that has come in from all around Arizona and the nation."

Last week, Kelly announced that he would fly a space shuttle mission that he's slated to command later this month. He had stopped training for the mission to be with Giffords after she was shot. He resumed training on Monday.
