SPACE SHUTTLE DISCOVERY'S ENGINE VALVE TO BE REPLACED
Admiral Richard H. Truly, NASA associate administrator for
space flight, and his management council today decided to proceed
with changing out the hydrogen bleed valve on Discovery's main
engine 2 prior to the flight readiness firing (FRF).
A new target date for the FRF will not be set until the
changeout process gets underway. However, based on what is
currently known, it appears that the FRF may occur as early as
late next week.
Truly indicated, "We are opting for a procedure which will
give us additional confidence to move forward to the FRF. I am
very pleased with the efforts of the teams who did the
troubleshooting on this situation and also with those who took us
through our recent countdown simulation activities."
