CAPE CANAVERAL, Fla. - The commander of the International Space Station says his brother will announce soon whether he'll blast off aboard shuttle Endeavour in April.
In an interview Wednesday with The Associated Press, Scott Kelly said his brother Mark is holding up well. He said his sister-in-law, wounded Congresswoman Gabrielle Giffords, is improving every day in rehab in Houston.
Scott and Mark Kelly are identical twins. Both are NASA astronauts.
Scott Kelly says their Navy background as high-performance pilots enables them to put their personal lives aside, when necessary, and focus on the job at hand. Scott says he'll support his brother's decision.
Mark Kelly is the commander of Endeavour's final flight. For now, another astronaut is substituting for him during training.
