A Yonkers man watched his astronaut son take a spacewalk Sunday.

The spacewalk was the third and final for Col. Ron Garan Jr. The 46-year-old Discovery specialist is in the midst of 14-day mission at the international space station.

Ron Garan Sr. watched a live stream of his son's walk on a computer. Garan says the idea of his son drifting through space made him nervous.

"I'm a little anxious today," he said. "I can't wait till he finishes up his spacewalk. It's a little dangerous."

Garan Jr., a Yonkers native, dreamed of becoming an astronaut ever since watching the first moon landing as a 7-year-old. He got his opportunity for a space flight on a mission full of tasks involving a Japanese science lab called Kibo.

The lab is roughly the size of a school bus and the largest ever addition to the station.

The astronaut was also able to phone home Saturday from outer space. His father expressed great pride in his son as both an astronaut and a man.

"I'm very proud of my son for his accomplishments as an astronaut, but I'm also proud of the character that he has," said Garan. "He's a wonderful human being."
