"Tanking Test" Still Set For Wednesday
At NASA's Kennedy
Space Center in Florida, repairs are nearing completion on the
plate that attaches a gaseous hydrogen vent line to space shuttle
Endeavour's external fuel tank. The new, two-piece seals were
installed and tightened Friday, new washers were installed Sunday
and the vent line has been reattached to the Ground Umbilical
Carrier Plate. Monday, the vent line bolts were tightened and the
line tested for leaks using helium at ambient temperatures.
The repairs will be verified Wednesday when Endeavour's external
tank is filled with liquid hydrogen and liquid oxygen. The tanking
test will start at 0700 EDT and last about three hours, followed by
a news conference to discuss the results. Both events will be shown
live on NASA TV.
Endeavour's airlock was closed and checked for leaks Friday.
Replacement spacesuit batteries will be stored in the orbiter's
middeck for flight. The next launch attempt for Endeavour is
targeted for July 11 at 1939.
Endeavour's STS-127 astronauts conducted an integrated entry
simulation Monday in the motion based simulator at NASA's Johnson
Space Center in Houston.
