Jan. 18, 2011— -- In a poignantly personal interview with ABC News' Diane Sawyer, astronaut Capt. Mark Kelly opens up about his wife Gabrielle Giffords' recovery and the Tucson shooting that injured her and killed six people.

Kelly, who has been photographed by his wife's hospital bed holding her hand, said there is a habit of hers that has convinced him that she recognizes him.

"If I hold her hand, she'll play with my wedding ring," he said. "She'll move it up and down my finger. She'll take it off. ... She'll put it on her own finger. She'll move it to her thumb. And then she can put it back on my finger.

"The reason why I know that that means she recognizes me is because she's done that before. She'll do that if we're sitting in a restaurant. She'll do the same exact movements," he said.

Kelly was struck by Giffords' progress again when "she stuck her hand up on the side of my face" and began giving him a neck massage.

"She spent 10 minutes rubbing my neck and I keep telling her, 'Gabby, you're in the ICU. You know, you don't need to be doing this," he said with a chuckle.

Kelly added, "I'm pretty sure she wouldn't do that to somebody else. And she's looking me in the eye."

Today's hopeful emotions are a world away from what was going through his mind a little more than a week ago when Kelly was in Houston and got a phone call from one of his wife's staffers, telling him his "Gabby" had been shot. He had spoken to his wife 30 minutes before.

"I picked up the phone and she says, 'I don't know how to tell you about this, but I just received a call ... and Gabby's been shot,'" Kelly told Sawyer. "I said, 'Well, that's, you know, that's not possible. Are you sure?'"

With no other information, Kelly ended the conversation and hung up his cell phone. He had to look at the phone's call history to make sure he hadn't imagined the news. He told his children -- Giffords' stepdaughters -- and then called Giffords' parents and his own. Then, there was one thought in his head.

"[I] quickly had to figure out how I'm going to get there very, you know, very fast," Kelly said.
