--------------------------------------------------------

Spacewalk to last at least six hours 
Liftoff of space shuttle 'Endeavour' from Launch Pad at NASA's Kennedy
Space Center in Florida Two astronauts aboard the U.S. space shuttle
Endeavour are on the final spacewalk of their mission, to continue work
on the International Space Station. The exercise is the fifth spacewalk
of Endeavour's mission.  Monday's work schedule for astronauts Chris
Cassidy and Tom Marshburn includes fixing insulation on a robot arm and
installing television cameras.   This final spacewalk is expected to
last six-and-a-half hours. Endeavour lifted off July 15 for a more than
two-week mission to help complete the space station.  The mission became
a little more complicated Saturday, when a space station air purifier
popped a circuit breaker and shut down.  Controllers managed to get it
working again in manual mode.  NASA plans to send a backup air purifier
during the next shuttle mission, scheduled for August. If all goes as
scheduled, Endeavour will leave the space station Tuesday and land at !
 Kennedy Space Center in Florida on Friday.
