Arizona Congresswoman Gabrielle Giffords made her first public appearance Monday in Houston, as she continues her remarkable recovery from the bullet wound she got at a January public event in Tucson.

Giffords attended an award ceremony for her husband, astronaut Mark Kelly, at Space Center Houston, the visitor center next door to the Johnson Space Center.  Kelly received the Spaceflight Medal, which NASA presents to space shuttle astronauts who return safely from their missions.

Giffords arrived in a wheelchair to a standing ovation from a crowd of hundreds.  She and Kelly held hands for most of the event, but she stood up to hug and kiss her husband when he received his medal.

Giffords was released from TIRR Memorial Hermann Hospital in Houston on June 15 after months of recovery from her bullet wound.  She now lives at home with her husband outside Houston, and gets continued TIRR treatment as an outpatient.

Writing on his Facebook Page, Mark Kelly reveals he has retired from NASA and the Navy so he can be with his wife full time and help her recover.

It's also reported that Kelly and Giffords are collaborating with a professional biographer on a joint memoir to tell the story of their lives together before and after the shooting.
