WEST ORANGE - A New Jersey school has changed its name to honor identical twin brothers and former students who went into space.

Retired astronauts Scott and Mark Kelly were on hand as the Pleasantdale Elementary School in West Orange became the Kelly Elementary School during a ceremony on Thursday.

The 52-year-old brothers grew up in the town and went through the public school system before becoming Navy pilots and NASA astronauts.

Scott retired in March, shortly after completing a 340-day mission at the International Space Station, the longest single spaceflight by an American. Scott has spent 520 days in space over four missions, also a U.S. record.

Mark flew four missions on the space shuttle, commanding NASA's next-to-last shuttle flight in 2011 and then retiring. He is married to former U.S. Rep. Gabrielle Giffords.
