Gladys Roscoe enjoys using technology to stay in touch with family, but the 93-year-old grandmother recently received a phone call like no other.

Col. Eric Boe took a break from his job piloting the space shuttle Discovery to call his "nana" from outer space.

The Discovery took its final lift off Monday and will return to earth for good on Thursday.

Although she often thinks about her grandson's safety, Roscoe said she didn't tell him that in heir brief phone conversation.

"I worry about him, but his father said 'Don't tell him that because he's been wanting to do this ever since he was a little boy,'" she said. "Say a little prayer -- that I did."

Roscoe attended the launch of the shuttle and plans to be there when it lands.

Boe tried to contact his nana from space during a previous mission, but he had to settle for an answering machine.

Roscoe missed the call because she was out square dancing.
