CAPE CANAVERAL, Fla. (AP) - Two science teachers who have spent
the past five years under NASA's tutelage are about to graduate
with high-flying honors.
The space shuttle flight Wednesday night of Joseph Acaba and
Richard Arnold II will mark the first time two former teachers have
rocketed into space together.
The flight on shuttle Discovery was delayed a month because of
concerns about hydrogen gas valves in the engine compartment.
After extra tests, NASA deemed the spacecraft safe to fly.
Discovery's astronauts arrived at the launch site Sunday
afternoon and thanked everyone who helped resolve the valve issue.
The countdown clocks began ticking four hours later.
