At a news conference on Friday, Kelly declined to discuss details of his wife’s condition. But he said he was planning on her being at Florida’s Kennedy Space Center for the targeted April 19 launch of Endeavour’s two-week mission, NASA’s last scheduled shuttle flight.
“She’s made progress every day,” Kelly said. “I have every intention that she’ll be there for the launch. I’ve already talked to her doctors about it. There really shouldn’t be any reason why she can’t go to the launch.”
Giffords is undergoing six hours a day of speech, occupational and physical therapy, Kelly said.
“She’s got very busy days,” Kelly said. “I started to think about my mission, my crew, the fact that I’ve been training for it for nearly a year and a half and considering a bunch of other factors, including what Gabrielle would want me to do and what her parents and her family and my family would like, I ultimately made the decision that I would like to return and command (the Endeavour) mission.”
