CAPE CANAVERAL, Fla. (AP) - Astronauts are carrying out the last
spacewalk of this mission to finish a clean and lube job that they
began a week ago at the international space station.
Spacewalkers Stephen Bowen and Shane Kimbrough will wrap up work on a jammed solar-wing rotary joint and, as a precaution, squirt
extra grease on another joint that is working.
Just before Monday's spacewalk began, NASA added a 16th day to
space shuttle Endeavour's mission.
Managers want to give the astronauts more time to fix a machine that's supposed to turn urine into drinking water.
As the spacewalk is going on, astronauts inside will work on the machine.
The water recycling equipment was delivered by Endeavour.
