Houston ChronicleCAPE CANAVERAL, Fla. -- Two more of NASA's classroom teachers turned astronauts have been assigned to their first spaceflights.
Ricky Arnold and Joe Acaba, who left teaching posts three years ago to join NASA's astronaut corps, are among seven astronauts assigned to the same assembly mission to the international space station. Scheduled for the fall of 2008, the mission will deliver the last of four solar power modules to the orbital outpost.
Their assignment, announced on Friday, comes of the heels of NASA astronaut Barbara Morgan's August shuttle flight. Morgan, who served as the backup to NASA's teacher-in-space Christa McAuliffe, flew after a 21-year wait. McAuliffe was among seven astronauts that perhished in the 1986 Challenger explosion.
Morgan,who resumed her teaching duties in McCall, Idaho, after the tragedy, was invited by NASA to train as a professional astronaut in 1998. A half-dozen years later, the space agency selected three more teachers to train for spaceflight.
