Saying there are "encouraging signs every day," the husband of Rep. Gabrielle Giffords (D-Ariz.) wrote Tuesday that the congresswoman is making a robust recovery since being shot in the head during a rampage in Tucson, Ariz., that left six dead and 13 wounded.
In a Facebook posting
on the one-month anniversary of the shooting, Navy Capt. Mark Kelly told supporters, "Your prayers are being heard."
Doctors say Giffords is recovering "at lightning speed considering her injury but they aren't kidding when they say this is a marathon process," Kelly, a NASA astronaut, continued in his post.
"Gabby's appetite is back and – even though it's hospital food – she's enjoying three meals a day," he wrote. "We can't thank you enough for the heartfelt show of support that has come in from all around Arizona and the nation."
He did not offer specifics of Giffords' injuries or her recovery.
The suspect in the shooting, 22-year-old Jared Loughner, has pleaded not guilty to charges that he tried to kill the congresswoman and two of her aides Jan. 8 outside a Tucson supermarket. Prosecutors are expected to file more charges, including murder, ahead of Loughner's trial in Phoenix.
"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," Kelly wrote.
, Kelly announced that he would command the Space Shuttle Endeavour when it takes off for a two-week orbital mission in mid-April.
